（来源：http://www.sciencedirect.com/）1. 1. 标题：High temperature long term stability of SiC Schottky diodes • Article 出处：Microelectronics Reliability, Volume 51, Issue 9-11, September 2011, Pages 1778-1782作者：Testa, A.; De Caro, S.; Russo, S.; Patti, D.; Torrisi, L. 摘要：Reliability of Silicon Carbide (SiC) power devices is still an open problem, preventing a wider application of such a promising technology. Moreover, specific reliability assessment procedures must be developed for SiC devices, as they are designed to work at temperatures well beyond those of standard Silicon devices. A detailed investigation about the reliability of 600 V, 6 A Silicon Carbide Schottky diodes is accomplished along this paper. It is based on an extensive set of high temperature reverse bias endurance tests, performed on devices featuring different packages. Only small forward voltage drop and reverse current drifts have been recorded after a 1000 h long test, confirming the parametric stability and the reliability level reached by last generation SiC Schottky diodes. Moreover, devices assembled in TO220 package without flame retardant components in the molding compound performed better than devices assembled in other TO220 packages, or assembled in hermetic TO3 package, pointing out the role played by the interface between the green molding compound and the top passivation layer in the long term parametric stability.

2. 标题：Synthesis of graphene-based nanosheets via chemical reduction of exfoliated graphite oxide • Article 出处：Carbon, Volume 45, Issue 7, June 2007, Pages 1558-1565作者：Stankovich, S.; Dikin, D.A.; Piner, R.D.; Kohlhaas, K.A.; Kleinhammes, A.; Jia, Y.; Wu, Y.; Nguyen, S.T.; Ruoff, R.S. 摘 要 ： Reduction of a colloidal suspension of exfoliated graphene oxide sheets in water with hydrazine hydrate results in their aggregation and subsequent formation of a high-surface-area carbon material which consists of thin graphene-based sheets. The reduced material was characterized by elemental analysis, thermo-gravimetric analysis, scanning electron microscopy, X-ray photoelectron spectroscopy, NMR spectroscopy, Raman spectroscopy, and by electrical conductivity measurements.

have been widely used experimentally for numerous in vivo applications such as magnetic resonance imaging contrast enhancement, tissue repair, immunoassay, detoxification of biological fluids, hyperthermia, drug delivery and in cell separation, etc. All these biomedical and bioengineering applications require that these nanoparticles have high magnetization values and size smaller than 100 nm with overall narrow particle size distribution, so that the particles have uniform physical and chemical properties. In addition, these applications need special surface coating of the magnetic particles, which has to be not only non-toxic and biocompatible but also allow a targetable delivery with particle localization in a specific area. To this end, most work in this field has been done in improving the biocompatibility of the materials, but only a few scientific investigations and developments have been carried out in improving the quality of magnetic particles, their size distribution, their shape and surface in addition to characterizing them to get a protocol for the quality control of these particles. Nature of surface coatings and their subsequent geometric arrangement on the nanoparticles determine not only the overall size of the colloid but also play a significant role in biokinetics and biodistribution of nanoparticles in the body. The types of specific coating, or derivatization, for these nanoparticles depend on the end application and should be chosen by keeping a particular application in mind, whether it be aimed at inflammation response or anti-cancer agents. Magnetic nanoparticles can bind to drugs, proteins, enzymes, antibodies, or nucleotides and can be directed to an organ, tissue, or tumour using an external magnetic field or can be heated in alternating magnetic fields for use in hyperthermia. This review discusses the synthetic chemistry, fluid stabilization and surface modification of superparamagnetic iron oxide nanoparticles, as well as their use for above biomedical applications.

Graphene and its derivatives are being studied in nearly every field of science and engineering. Recent progress has shown that the graphene-based materials can have a profound impact on electronic and optoelectronic devices, chemical sensors, nanocomposites and energy storage. The aim of this review article is to provide a comprehensive scientific progress of graphene to date and evaluate its future perspective. Various synthesis processes of single layer graphene, graphene nanoribbons, chemically derived graphene, and graphene-based polymer and nano particle composites are reviewed. Their structural, thermal, optical, and electrical properties were also discussed along with their potential applications. The article concludes with a brief discussion on the impact of graphene and related materials on the environment, its toxicological effects and its future prospects in this rapidly emerging field.

摘要：This paper reviews recent advances in the modification of graphene and the fabrication of graphene-based polymer nanocomposites. Recently, graphene has attracted both academic and industrial interest because it can produce a dramatic improvement in properties at very low filler content. The modification of graphene/graphene oxide and the utilization of these materials in the fabrication of nanocomposites with different polymer matrixes have been explored. Different organic polymers have been used to fabricate graphene filled polymer nanocomposites by a range of methods. In the case of modified graphene-based polymer nanocomposites, the percolation threshold can be achieved at a very lower filler loading. Herein, the structure, preparation and properties of polymer/graphene nanocomposites are discussed in general along with detailed examples drawn from the scientific literature.

6. 标题：Lithium batteries: Status, prospects and future • Review article 出处：Journal of Power Sources, Volume 195, Issue 9, May 2010, Pages 2419-2430作者：Scrosati, B.; Garche, J. 摘要：Lithium batteries are characterized by high specific energy, high efficiency and long life. These unique properties have made lithium batteries the power sources of choice for the consumer electronics market with a production of the order of billions of units per year. These batteries are also expected to find a prominent role as ideal electrochemical storage systems in renewable energy plants, as well as power systems for sustainable vehicles, such as hybrid and electric vehicles. However, scaling up the lithium battery technology for these applications is still problematic since issues such as safety, costs, wide operational temperature and materials availability, are still to be resolved. This review focuses first on the present status of lithium battery technology, then on its near future development and finally it examines important new directions aimed at achieving quantum jumps in energy and power content.

7. 标题：Surface modification of inorganic nanoparticles for development of organic-inorganic nanocomposites-A review • Review article 出处：Progress in Polymer Science, Volume 38, Issue 8, August 2013, Pages 1232-1261作者：Kango, S.; Kalia, S.; Celli, A.; Njuguna, J.; Habibi, Y.; Kumar, R. 摘 要 ： Nanoparticles and nanocomposites are used in a wide range of applications in various fields, such as medicine, textiles, cosmetics, agriculture, optics, food packaging, optoelectronic devices, semiconductor devices, aerospace, construction and catalysis. Nanoparticles can be incorporated into polymeric nanocomposites. Polymeric nanocomposites consisting of inorganic nanoparticles and organic polymers represent a new class of materials that exhibit improved performance compared to their microparticle counterparts. It is therefore expected that they will advance the field of engineering applications. Incorporation of inorganic nanoparticles into a polymer matrix can significantly affect the properties of the matrix. The resulting composite might exhibit improved thermal, mechanical, rheological, electrical, catalytic, fire retardancy and optical properties. The properties of polymer composites depend on the type of nanoparticles that are incorporated, their size and shape, their concentration and their interactions with the polymer matrix. The main problem with polymer nanocomposites is the prevention of particle aggregation. It is difficult to produce monodispersed nanoparticles in a polymer matrix because nanoparticles agglomerate due to their specific surface area and volume effects. This problem can be overcome by modification of the surface of the inorganic particles. The modification improves the interfacial

interactions between the inorganic particles and the polymer matrix. There are two ways to modify the surface of inorganic particles. The first is accomplished through surface absorption or reaction with small molecules, such as silane coupling agents, and the second method is based on grafting polymeric molecules through covalent bonding to the hydroxyl groups existing on the particles. The advantage of the second procedure over the first lies in the fact that the polymer-grafted particles can be designed with the desired properties through a proper selection of the species of the grafting monomers and the choice of grafting conditions.

8. 标题：The surface science of titanium dioxide • Review article 出处：Surface Science Reports, Volume 48, Issue 5-8, January 2003, Pages 53-229作者：Diebold, U. 摘要：Titanium dioxide is the most investigated single-crystalline system in the surface science of metal oxides, and the literature on rutile (1 1 0), (1 0 0), (0 0 1), and anatase surfaces is reviewed. This paper starts with a summary of the wide variety of technical fields where TiO2 is of importance. The bulk structure and bulk defects (as far as relevant to the surface properties) are briefly reviewed. Rules to predict stable oxide surfaces are exemplified on rutile (1 1 0). The surface structure of rutile (1 1 0) is discussed in some detail. Theoretically predicted and experimentally determined relaxations of surface geometries are compared, and defects (step edge orientations, point and line defects, impurities, surface manifestations of crystallographic shear planes—CSPs) are discussed, as well as the image contrast in scanning tunneling microscopy (STM). The controversy about the correct model for the (1×2) reconstruction appears to be settled. Different surface preparation methods, such as reoxidation of reduced crystals, can cause a drastic effect on surface geometries and morphology, and recommendations for preparing different TiO2(1 1 0) surfaces are given. The structure of the TiO2(1 0 0)-(1×1) surface is discussed and the proposed models for the (1×3) reconstruction are critically reviewed. Very recent results on anatase (1 0 0) and (1 0 1) surfaces are included.The electronic structure of stoichiometric TiO2 surfaces is now well understood. Surface defects can be detected with a variety of surface spectroscopies. The vibrational structure is dominated by strong Fuchs–Kliewer phonons, and high-resolution electron energy loss spectra often need to be deconvoluted in order to render useful information about adsorbed molecules.The growth of metals (Li, Na, K, Cs, Ca, Al, Ti, V, Nb, Cr, Mo, Mn, Fe, Co, Rh, Ir, Ni, Pd, Pt, Cu, Ag, Au) as well as some metal oxides on TiO2 is reviewed. The tendency to ‘wet’ the overlayer, the growth morphology, the epitaxial relationship, and the strength of the interfacial oxidation/reduction reaction all follow clear trends across the periodic table, with the reactivity of the overlayer metal towards oxygen being the most decisive factor. Alkali atoms form ordered superstructures at low coverages. Recent progress in understanding the surface structure of metals in the ‘strong-metal support interaction’ (SMSI) state is summarized.Literature is reviewed on the adsorption and reaction of a wide variety of inorganic molecules (H2, O2, H2O, CO, CO2, N2, NH3, NOx, sulfur- and halogen-containing molecules, rare gases) as well as organic molecules (carboxylic acids, alcohols, aldehydes and ketones, alkynes, pyridine and its derivates, silanes, methyl halides). The application of TiO2-based systems in photo-active devices is discussed, and the results on UHV-based photocatalytic studies are summarized.The review ends with a brief conclusion and outlook of TiO2-based surface science for the future.

9. 标 题 ： A review on polymer nanofibers by electrospinning and their applications in nanocomposites • Article 出处：Composites Science and Technology, Volume 63, Issue 15, November 2003, Pages 2223-2253作者：Huang, Z.-M.; Zhang, Y.-Z.; Kotaki, M.; Ramakrishna, S. 摘 要 ： Electrospinning has been recognized as an efficient technique for the fabrication of polymer nanofibers. Various polymers have been successfully electrospun into ultrafine fibers in recent years mostly in solvent solution and some in melt form. Potential applications based on such fibers specifically their use as reinforcement in nanocomposite development have been realized. In this paper, a comprehensive review is presented on the researches and developments related to electrospun polymer nanofibers including processing, structure and property characterization, applications, and modeling and simulations. Information of those polymers together with their processing conditions for electrospinning of ultrafine fibers has been summarized in the paper. Other issues regarding the technology limitations, research challenges, and future trends are also discussed.

10. 标题：TiO"2 photocatalysis and related surface phenomena • Review article 出处：Surface Science Reports, Volume 63, Issue 12, December 2008, Pages 515-582作者：Fujishima, A.; Zhang, X.; Tryk, D.A. 摘要：The field of photocatalysis can be traced back more than 80 years to early observations of the chalking of titania-based paints and to studies of the darkening of metal oxides in contact with organic compounds in sunlight. During the past 20 years, it has become an extremely well researched field due to practical interest in air and water remediation, self-cleaning surfaces, and self-sterilizing surfaces. During the same period, there has also been a strong effort to use photocatalysis for light-assisted production of hydrogen. The fundamental aspects of photocatalysis on the most studied photocatalyst, titania, are still being actively researched and have recently become quite well understood. The mechanisms by which certain types of organic compounds are decomposed completely to carbon dioxide and water, for example, have been delineated. However, certain aspects, such as the photo-induced wetting phenomenon, remain controversial, with some groups maintaining that the effect is a simple one in which organic contaminants are decomposed, while other groups maintain that there are additional effects in which the intrinsic surface properties are modified by light. During the past several years, powerful tools such as surface spectroscopic techniques and scanning probe techniques performed on single crystals in ultra-high vacuum, and ultrafast pulsed laser spectroscopic techniques have been brought to bear on these problems, and new insights have become possible. Quantum chemical calculations have also provided new insights. New materials have recently been developed based on titania, and the sensitivity to visible light has improved. The new information available is staggering, but we hope to offer an overview of some of the recent highlights, as well as to review some of the origins and indicate some possible new directions.

engineering research. A number of biodegradable and bioresorbable materials, as well as scaffold designs, have been experimentally and/or clinically studied. Ideally, a scaffold should have the following characteristics: (i) three-dimensional and highly porous with an interconnected pore network for cell growth and flow transport of nutrients and metabolic waste; (ii) biocompatible and bioresorbable with a controllable degradation and resorption rate to match cell/tissue growth in vitro and/or in vivo; (iii) suitable surface chemistry for cell attachment, proliferation, and differentation and (iv) mechanical properties to match those of the tissues at the site of implantation. This paper reviews research on the tissue engineering of bone and cartilage from the polymeric scaffold point of view.

12. 标 题 ： Carbon nanotube-polymer composites: Chemistry, processing, mechanical and electrical properties • Review article 出处：Progress in Polymer Science, Volume 35, Issue 3, March 2010, Pages 357-401作者：Spitalsky, Z.; Tasis, D.; Papagelis, K.; Galiotis, C. 摘 要 ： Carbon nanotubes have long been recognized as the stiffest and strongest man-made material known to date. In addition, their high electrical conductivity has roused interest in the area of electrical appliances and communication related applications. However, due to their miniscule size, the excellent properties of these nanostructures can only be exploited if they are homogeneously embedded into light-weight matrices as those offered by a whole series of engineering polymers. We review the present state of polymer nanocomposites research in which the fillers are carbon nanotubes. In order to enhance their chemical affinity to engineering polymer matrices, chemical modification of the graphitic sidewalls and tips is necessary. In this review, an extended account of the various chemical strategies for grafting polymers onto carbon nanotubes and the manufacturing of carbon nanotube/polymer nanocomposites is given. The mechanical and electrical properties to date of a whole range of nanocomposites of various carbon nanotube contents are also reviewed in an attempt to facilitate progress in this emerging area.

It has become of great interest not only as an underutilized resource, but also as a new functional material of high potential in various fields, and recent progress in chitin chemistry is quite noteworthy. The purpose of this review is to take a closer look at chitin and chitosan applications. Based on current research and existing products, some new and futuristic approaches in this fascinating area are thoroughly discussed.

15. 标题：Hydrogels for tissue engineering: scaffold design variables and applications出处：Biomaterials, Volume 24, Issue 24, November 2003, Pages 4337-4351作者：Drury, J.L.; Mooney, D.J. 摘要：Polymer scaffolds have many different functions in the field of tissue engineering. They are applied as space filling agents, as delivery vehicles for bioactive molecules, and as three-dimensional structures that organize cells and present stimuli to direct the formation of a desired tissue. Much of the success of scaffolds in these roles hinges on finding an appropriate material to address the critical physical, mass transport, and biological design variables inherent to each application. Hydrogels are an appealing scaffold material because they are structurally similar to the extracellular matrix of many tissues, can often be processed under relatively mild conditions, and may be delivered in a minimally invasive manner. Consequently, hydrogels have been utilized as scaffold materials for drug and growth factor delivery, engineering tissue replacements, and a variety of other applications.

16. 标题：Graphene and graphene oxide as new nanocarriers for drug delivery applications 出处：Acta Biomaterialia, Volume 9, Issue 12, December 2013, Pages 9243-9257作者：Liu, J.; Cui, L.; Losic, D. 摘 要 ： The biomedical applications of graphene-based materials, including drug delivery, have grown rapidly in the past few years. Graphene and graphene oxide have been extensively explored as some of the most promising biomaterials for biomedical applications due to their unique properties: two-dimensional planar structure, large surface area, chemical and mechanical stability, superb conductivity and good biocompatibility. These properties result in promising applications for the design of advanced drug delivery systems and delivery of a broad range of therapeutics. In this review we present an overview of recent advances in this field of research. We briefly describe current methods for the surface modification of graphene-based nanocarriers, their biocompatibility and toxicity, followed by a summary of the most appealing examples demonstrated for the delivery of anti-cancer drugs and genes. Additionally, new drug delivery concepts based on controlling mechanisms, including targeting and stimulation with pH, chemical interactions, thermal, photo- and magnetic induction, are discussed. Finally the review is summarized, with a brief conclusion of future prospects and challenges in this field.

Various nanoparticulate systems, general synthesis and encapsulation process, control release and improvement of therapeutic value of nanoencapsulated drugs are covered in this review. We have highlighted the impact of nanoencapsulation of various disease related drugs on biodegradable nanoparticles such as PLGA, PLA, chitosan, gelatin, polycaprolactone and poly-alkyl-cyanoacrylates.

18. 标题：Polymer nanoparticles: Preparation techniques and size-control parameters Progress in 出处：Polymer Science, Volume 36, Issue 7, July 2011, Pages 887-913作者：Rao, J.P.; Geckeler, K.E. 摘要：Polymer nanoparticles have attracted the interest of many research groups and have been utilized in an increasing number of fields during the last decades. Generally, two main strategies are employed for their preparation: the dispersion of preformed polymers and the polymerization of monomers. Various techniques can be used to produce polymer nanoparticles, such as solvent evaporation, salting-out, dialysis, supercritical fluid technology, micro-emulsion, mini-emulsion, surfactant-free emulsion, and interfacial polymerization. The choice of method depends on a number of factors, such as, particle size, particle size distribution, area of application, etc. This review covers the general description of the preparation of polymer nanoparticles and the detailed description of the crucial parameters involved in techniques designed to obtain the desired properties.

19. 标题：Bio-nanocomposites for food packaging applications • Review article 出处：Progress in Polymer Science, Volume 38, Issue 10-11, October 2013, Pages 1629-1652作者：Rhim, J.W.; Park, H.M.; Ha, C.S. 摘 要 ： There is growing interest in developing bio-based polymers and innovative process technologies that can reduce the dependence on fossil fuel and move to a sustainable materials basis. Bio-nanocomposites open an opportunity for the use of new, high performance, light weight green nanocomposite materials making them to replace conventional non-biodegradable petroleum-based plastic packaging materials.

So far, the most studied bio-nanocomposites suitable for packaging applications are starch and cellulose derivatives, polylactic acid (PLA), polycaprolactone (PCL), poly(butylene succinate) (PBS) and polyhydroxybutyrate (PHB). The most promising nanoscale fillers are layered silicate nanoclays such as montmorillonite and kaolinite. In food packaging, a major emphasis is on the development of high barrier properties against the diffusion of oxygen, carbon dioxide, flavor compounds, and water vapor.

Moreover, several nanostructures can be useful to provide active and/or smart properties to food packaging systems, as exemplified by antimicrobial properties, oxygen scavenging ability, enzyme immobilization, or indication of the degree of exposure to some detrimental factors such as

8

inadequate temperatures or oxygen levels. Challenges remain in increasing the compatibility between clays and polymers and reaching complete dispersion of nanoparticles.

This review focuses on the enhancement of packaging performance of the green materials as well as their biodegradability, antimicrobial properties, and mechanical and thermal properties for food packaging application. The preparation, characterization and application of biopolymer-based nanocomposites with organic layered silicate and other fillers, and their application in the food packaging sector are also discussed.

20. 标题：Recent developments in cathode materials for lithium ion batteries • Review article 出处：Journal of Power Sources, Volume 195, Issue 4, February 2010, Pages 939-954作者：Fergus, J.W. 摘 要 ： One of the challenges for improving the performance of lithium ion batteries to meet increasingly demanding requirements for energy storage is the development of suitable cathode materials. Cathode materials must be able to accept and release lithium ions repeatedly (for recharging) and quickly (for high current). Transition metal oxides based on the α-NaFeO2, spinel and olivine structures have shown promise, but improvements are needed to reduce cost and extend effective lifetime. In this paper, recent developments in cathode materials for lithium ion batteries are reviewed. This includes comparison of the performance characteristics of the promising cathode materials and approaches for improving their performances.

21. 标题：Biocomposites reinforced with natural fibers: 2000-2010 • Review article 出处：Progress in Polymer Science, Volume 37, Issue 11, November 2012, Pages 1552-1596作者：Faruk, O.; Bledzki, A.K.; Fink, H.P.; Sain, M. 摘 要 ： Due to environment and sustainability issues, this century has witnessed remarkable achievements in green technology in the field of materials science through the development of biocomposites. The development of high-performance materials made from natural resources is increasing worldwide. The greatest challenge in working with natural fiber reinforced plastic composites is their large variation in properties and characteristics. A biocomposite's properties are influenced by a number of variables, including the fiber type, environmental conditions (where the plant fibers are sourced), processing methods, and any modification of the fiber. It is also known that recently there has been a surge of interest in the industrial applications of composites containing biofibers reinforced with biopolymers. Biopolymers have seen a tremendous increase in use as a matrix for biofiber reinforced composites. A comprehensive review of literature (from 2000 to 2010) on the mostly readily utilized natural fibers and biopolymers is presented in this paper. The overall characteristics of reinforcing fibers used in biocomposites, including source, type, structure, composition, as well as mechanical properties, will be reviewed. Moreover, the modification methods; physical (corona and plasma treatment) and chemical (silane, alkaline, acetylation, maleated coupling, and enzyme treatment) will be discussed. The most popular matrices in biofiber reinforced composites based on petrochemical and renewable resources will also be addressed. The wide variety of biocomposite processing techniques as well as the factors (moisture content, fiber type and content, coupling agents and their influence on composites properties) affecting these processes will be discussed. Prior to the processing of biocomposites, semi-finished product manufacturing is also vital, which will be illustrated. Processing

9

technologies for biofiber reinforced composites will be discussed based on thermoplastic matrices (compression molding, extrusion, injection molding, LFT-D-method, and thermoforming), and thermosets (resin transfer molding, sheet molding compound). Other implemented processes, i.e., thermoset compression molding and pultrusion and their influence on mechanical performance (tensile, flexural and impact properties) will also be evaluated. Finally, the review will conclude with recent developments and future trends of biocomposites as well as key issues that need to be addressed and resolved.

22. 标题：Fabrication and processing of polymer solar cells: A review of printing and coating techniques • Review article 出处：Solar Energy Materials and Solar Cells, Volume 93, Issue 4, April 2009, Pages 394-412作者：Krebs, F.C. 摘 要 ： Polymer solar cells are reviewed in the context of the processing techniques leading to complete devices. A distinction is made between the film-forming techniques that are used currently such as spincoating, doctor blading and casting and the, from a processing point of view, more desirable film-forming techniques such as slot-die coating, gravure coating, knife-over-edge coating, off-set coating, spray coating and printing techniques such as ink jet printing, pad printing and screen printing. The former are used almost exclusively and are not suited for high-volume production whereas the latter are highly suited, but little explored in the context of polymer solar cells. A further distinction is made between printing and coating when a film is formed. The entire process leading to polymer solar cells is broken down into the individual steps and the available techniques and materials for each step are described with focus on the particular advantages and disadvantages associated with each case.

23. 标题：Organic-inorganic hybrid solar cells: A comparative review • Review article 出处：Solar Energy Materials and Solar Cells, Volume 107, December 2012, Pages 87-111作者：Wright, M.; Uddin, A. 摘要：Organic materials have recently become of great interest for photovoltaic applications, due to their potential to utilise high throughput, solution phase processing, which will lead to low cost electricity production. Hybrid solar cells combine organic and inorganic materials with the aim of utilising the low cost cell production of organic photovoltaics (OPV) as well as obtaining other advantages, such as tuneable absorption spectra, from the inorganic component. Whilst hybrid solar cells have the potential to achieve high power conversion efficiencies (PCE), currently obtained efficiencies are quite low. The design of the inorganic material used as the electron acceptor in hybrid solar cells, particularly the electronic structure, is crucial to the performance of the device. There exists an optimal electronic structure design for an inorganic acceptor. To date, four major material types have been investigated, being cadmium compounds, silicon, metal oxide nanoparticles and low band gap nanoparticles. Currently, Cadmium Sulfide (CdS) quantum dots represent the state of the art, yielding a PCE of greater than 4%. This review compares the electronic structure of these materials with the optimal design components of an inorganic material and also explores possible limitations to the PCE of these devices, such as nanomorphology control and nanoparticle surface chemistry. This report provides the reader with a concise synthesis of the current state of the art for bulk heterojunction organic—inorganic hybrid solar cells. Additionally, it highlights key research areas which require attention to allow for the

10

commercialisation of this technology.

The main sources exploited are two marine crustaceans, shrimp and crabs. Our objective is to appraise the state of the art concerning this polysaccharide: its morphology in the native solid state, methods of identification and characterization and chemical modifications, as well as the difficulties in utilizing and processing it for selected applications. We note the important work of P. Austin, S. Tokura and S. Hirano, who have contributed to the applications development of chitin, especially in fiber form. Then, we discuss chitosan, the most important derivative of chitin, outlining the best techniques to characterize it and the main problems encountered in its utilization. Chitosan, which is soluble in acidic aqueous media, is used in many applications (food, cosmetics, biomedical and pharmaceutical applications). We briefly describe the chemical modifications of chitosan—an area in which a variety of syntheses have been proposed tentatively, but are not yet developed on an industrial scale. This review emphasizes recent papers on the high value-added applications of these materials in medicine and cosmetics.

Degradable polymeric biomaterials are preferred candidates for developing therapeutic devices such as temporary prostheses, three-dimensional porous structures as scaffolds for tissue engineering and as controlled/sustained release drug delivery vehicles. Each of these applications demands materials with specific physical, chemical, biological, biomechanical and degradation properties to provide efficient therapy. Consequently, a wide range of natural or synthetic polymers capable of undergoing degradation by hydrolytic or enzymatic route are being investigated for biomedical applications. This review summarizes the main advances published over the last 15 years, outlining the synthesis, biodegradability and biomedical applications of biodegradable synthetic and natural polymers.

Moreover, specific reliability assessment procedures must be developed for SiC devices, as they are designed to work at temperatures well beyond those of standard Silicon devices. A detailed investigation about the reliability of 600 V, 6 A Silicon Carbide Schottky diodes is accomplished along this paper. It is based on an extensive set of high temperature reverse bias endurance tests, performed on devices featuring different packages. Only small forward voltage drop and reverse current drifts have been recorded after a 1000 h long test, confirming the parametric stability and the reliability level reached by last generation SiC Schottky diodes. Moreover, devices assembled in TO220 package without flame retardant components in the molding compound performed better than devices assembled in other TO220 packages, or assembled in hermetic TO3 package, pointing out the role played by the interface between the green molding compound and the top passivation layer in the long term parametric stability.

2. 标题：Analytical and numerical study of photocurrent transients in organic polymer solar cells 出处：Computer Methods in Applied Mechanics and Engineering, Volume 199, Issue 25-28, May 2010, Pages 1722-1732作者：de Falco, C.; Sacco, R.; Verri, M. 摘要：This article is an attempt to provide a self consistent picture, including existence analysis and numerical solution algorithms, of the mathematical problems arising from modeling photocurrent transients in organic polymer solar cells (OSCs). The mathematical model for OSCs consists of a system of nonlinear diffusion–reaction partial differential equations (PDEs) with electrostatic convection, coupled to a kinetic ordinary differential equation (ODE). We propose a suitable reformulation of the model that allows us to prove the existence of a solution in both stationary and transient conditions and to better highlight the role of exciton dynamics in determining the device turn-on time. For the numerical treatment of the problem, we carry out a temporal semi-discretization using an implicit adaptive method, and the resulting sequence of differential subproblems is linearized using the Newton–Raphson method with inexact evaluation of the Jacobian. Then, we use exponentially fitted finite elements for the spatial discretization, and we carry out a thorough validation of the computational model by extensively investigating the impact of the model parameters on photocurrent transient times.

applications • Review article 出处：Biomaterials, Volume 26, Issue 18, June 2005, Pages 3995-4021作者：Gupta, A.K.; Gupta, M. 摘要：Superparamagnetic iron oxide nanoparticles (SPION) with appropriate surface chemistry have been widely used experimentally for numerous in vivo applications such as magnetic resonance imaging contrast enhancement, tissue repair, immunoassay, detoxification of biological fluids, hyperthermia, drug delivery and in cell separation, etc. All these biomedical and bioengineering applications require that these nanoparticles have high magnetization values and size smaller than 100 nm with overall narrow particle size distribution, so that the particles have uniform physical and chemical properties. In addition, these applications need special surface coating of the magnetic particles, which has to be not only non-toxic and biocompatible but also allow a targetable delivery with particle localization in a specific area. To this end, most work in this field has been done in improving the biocompatibility of the materials, but only a few scientific investigations and developments have been carried out in improving the quality of magnetic particles, their size distribution, their shape and surface in addition to characterizing them to get a protocol for the quality control of these particles. Nature of surface coatings and their subsequent geometric arrangement on the nanoparticles determine not only the overall size of the colloid but also play a significant role in biokinetics and biodistribution of nanoparticles in the body. The types of specific coating, or derivatization, for these nanoparticles depend on the end application and should be chosen by keeping a particular application in mind, whether it be aimed at inflammation response or anti-cancer agents. Magnetic nanoparticles can bind to drugs, proteins, enzymes, antibodies, or nucleotides and can be directed to an organ, tissue, or tumour using an external magnetic field or can be heated in alternating magnetic fields for use in hyperthermia. This review discusses the synthetic chemistry, fluid stabilization and surface modification of superparamagnetic iron oxide nanoparticles, as well as their use for above biomedical applications.

6. 标题：A survey on security issues in service delivery models of cloud computing 出处：Journal of Network and Computer Applications, Volume 34, Issue 1, January 2011, Pages 1-11作者：Subashini, S.; Kavitha, V. 摘要：Cloud computing is a way to increase the capacity or add capabilities dynamically without investing in new infrastructure, training new personnel, or licensing new software. It extends Information Technology’s (IT) existing capabilities. In the last few years, cloud computing has grown from being a promising business concept to one of the fast growing segments of the IT industry. But as more and more information on individuals and companies are placed in the cloud, concerns are beginning to grow about just how safe an environment it is. Despite of all the hype surrounding the cloud, enterprise customers are still reluctant to deploy their business in the cloud. Security is one of the major issues which reduces the growth of cloud computing and complications with data privacy and data protection continue to plague the market. The advent of an advanced model should not negotiate with the required functionalities and capabilities present in the current model. A new model targeting at improving features of an existing model must not risk or threaten other important features of the current model. The architecture of cloud poses such a threat to the security of the existing technologies when deployed in a cloud environment. Cloud service users need to be vigilant in understanding the risks of data breaches in this new environment. In this paper, a survey of the different security risks that pose a threat to the cloud is presented. This paper is a survey more specific to the different security issues that has emanated due to the nature of the service delivery models of a cloud computing system.

The global contribution from buildings towards energy consumption, both residential and commercial, has steadily increased reaching figures between 20% and 40% in developed countries, and has exceeded the other major sectors: industrial and transportation. Growth in population, increasing demand for building services and comfort levels, together with the rise in time spent inside buildings, assure the upward trend in energy demand will continue in the future. For this reason, energy efficiency in buildings is today a prime objective for energy policy at regional, national and international levels. Among building services, the growth in HVAC systems energy use is particularly significant (50% of building consumption and 20% of total consumption in the USA). This paper analyses available information concerning energy consumption in buildings, and particularly related to HVAC systems. Many questions arise: Is the necessary information available? Which are the main building types? What end uses should be considered in the breakdown? Comparisons between different countries are presented

specially for commercial buildings. The case of offices is analysed in deeper detail.

14. 标题：Hydrogels for tissue engineering: scaffold design variables and applications出处：Biomaterials, Volume 24, Issue 24, November 2003, Pages 4337-4351作者：Drury, J.L.; Mooney, D.J. 摘要：Polymer scaffolds have many different functions in the field of tissue engineering. They are applied as space filling agents, as delivery vehicles for bioactive molecules, and as three-dimensional structures that organize cells and present stimuli to direct the formation of a desired tissue. Much of the success of scaffolds in these roles hinges on finding an appropriate material to address the critical physical, mass transport, and biological design variables inherent to each application. Hydrogels are an appealing scaffold material because they are structurally similar to the extracellular matrix of many tissues, can often be processed under relatively mild conditions, and may be delivered in a minimally invasive manner. Consequently, hydrogels have been utilized as scaffold materials for drug and growth factor delivery, engineering tissue replacements, and a variety of other applications.

Research on object recognition algorithms has led to advances in factory and office automation through the creation of optical character recognition systems, assembly-line industrial inspection systems, as well as chip defect identification systems. It has also led to significant advances in medical imaging, defence and biometrics. In this paper we

17

discuss the evolution of computer-based object recognition systems over the last fifty years, and overview the successes and failures of proposed solutions to the problem. We survey the breadth of approaches adopted over the years in attempting to solve the problem, and highlight the important role that active and attentive approaches must play in any solution that bridges the semantic gap in the proposed object representations, while simultaneously leading to efficient learning and inference algorithms. From the earliest systems which dealt with the character recognition problem, to modern visually-guided agents that can purposively search entire rooms for objects, we argue that a common thread of all such systems is their fragility and their inability to generalize as well as the human visual system can. At the same time, however, we demonstrate that the performance of such systems in strictly controlled environments often vastly outperforms the capabilities of the human visual system. We conclude our survey by arguing that the next step in the evolution of object recognition algorithms will require radical and bold steps forward in terms of the object representations, as well as the learning and inference algorithms used.

17. 标题：A vision-based blind spot warning system for daytime and nighttime driver assistance出处：Computers & Electrical Engineering, Volume 39, Issue 3, April 2013, Pages 846-862作者：Wu, B.F.; Huang, H.Y.; Chen, C.J.; Chen, Y.H.; Chang, C.W.; Chen, Y.L. 摘 要 ： This paper proposes an effective blind spot warning system (BSWS) for daytime and nighttime conditions. The proposed BSWS includes camera models of a dynamic calibration and blind spot detection (BSD) algorithms for the daytime and nighttime. Under daytime conditions, the proposed system presents the Horizontal Edge and Shadow Composite Region (HESCR) method to extract the searching region and to acquire the shadow location of the targeted vehicles. Additionally, to detect vehicles at nighttime road scenes, the proposed system extracts bright objects and recognizes the paired headlights of the targeted vehicles for the BSD. The BSWS is implemented on a DSP-based embedded platform. The results of the BSWS are obtained by conducting practical experiments on our camera-assisted car on a highway in Taiwan under both nighttime and daytime conditions. Experimental results show that the proposed BSWS is feasible for vehicle detection and collision warning in various daytime and nighttime road environments.

For this purpose, we improve the contrast at possible locations where there might be a license plate, we propose a filtering method called “region-based” in order to smooth the uniform and background areas of an image, we apply the Sobel operator and morphological filtering to extract the vertical edges and the candidate regions respectively, and finally, we segment the plate region by considering some geometrical features. In fact the novelty and the strength of our license plate detection system is in applying the region-based filtering that decreases the run time and increases the accuracy in the two final stages: morphological filtering and using the geometrical features. The experimental results show that our proposed method achieves appropriate performance in different scenarios. We should mention that our system is reliable because the accuracy is above 92% in average for different scenarios and it is also practical because of the low computational cost.

20. 标 题 ： Improving the embedding efficiency of weight matrix-based steganography for grayscale images • Article 出处：Computers & Electrical Engineering, Volume 39, Issue 3, April 2013, Pages 873-881作者：Fan, L.; Gao, T.; Cao, Y. 摘要：This paper firstly reviews a classical data hiding scheme based on weight matrix, and then indicates the possibility of improving the embedding efficiency and payload of it when it is applied to grayscale images. An improved steganographic scheme is subsequently proposed to not only accomplish the goal of improving the performance, but also remedy a security vulnerability of previous scheme in a special case of fully-embedding pattern by employing random permutation rather than binary matrix exclusive-or operation. Different from two-bit modification in Tseng’s scheme, we use the pixel as the element of embedded block Fi, i.e. [Fi]j,k ∈ [0,255]. We can add or subtract a given value to the SUM arbitrarily by modifying only one pixel, which guarantees the imperceptibility effectively. Additionally, the embedding efficiency and payload of proposed scheme will be both increasing at the same time. The experimental results also demonstrate that the proposed scheme is superior to the previous technique in terms of performance and security.

All their properties have to be tuned to achieve the best anti-infective performance together with safe biocompatibility and appropriate tissue interactions. Innovative technologies are developing new biomaterials and surfaces endowed with anti-infective properties, relying either on antifouling, or bactericidal, or antibiofilm activities. This review aims at thoroughly surveying the numerous classes of antibacterial biomaterials and the underlying strategies behind them.

Bacteria repelling and antiadhesive surfaces, materials with intrinsic antibacterial properties, antibacterial coatings, nanostructured materials, and molecules interfering with bacterial biofilm are considered. Among the new strategies, the use of phages or of antisense peptide nucleic acids are discussed, as well as the possibility to modulate the local immune response by active cytokines. Overall, there is a wealth of technical solutions to contrast the establishment of an implant infection. Many of them exhibit a great potential in preclinical models. The lack of well-structured prospective multicenter clinical trials hinders the achievement of conclusive data on the efficacy and comparative performance of anti-infective biomaterials.

Materials and fabrication routes for three-dimensional (3D) scaffolds with interconnected high porosities suitable for bone tissue engineering are reviewed. Different polymer and ceramic compositions applied and their impact on biodegradability and bioactivity of the scaffolds are discussed, including in vitro and in vivo assessments. The mechanical properties of today's available porous scaffolds are analyzed in detail, revealing insufficient elastic stiffness and compressive strength compared to human bone. Further challenges in scaffold fabrication for tissue engineering such as biomolecules incorporation, surface functionalization and 3D scaffold characterization are discussed, giving possible solution strategies. Stem cell incorporation into scaffolds as a future trend is addressed shortly, highlighting the immense potential for creating next-generation synthetic/living composite biomaterials that feature high adaptiveness to the biological environment.

We reduce the number of needed images to establish the complete 3D objects by combining Wide Baseline Matching and 3D registration algorithm. We reduce the loss of edge and corner information by applying line detection and guided matching in Narrow Baseline Matching. We perform projective reconstruction with a dynamic threshold, and eliminate the ambiguity in Euclidean reconstruction by motion consistency constraint. We propose a fast linear method for motion calculation to recover the motion of key frames with a succinct method to obtain motion vector by solving linear equation set. We adopt a novel display system, which features high refresh rate, large size and high intensity screen, to provide live display of 3D objects.

24. 标 题 ： A robust digital watermarking algorithm in undecimated discrete wavelet transform domain • Article 出处：Computers & Electrical Engineering, Volume 39, Issue 3, April 2013, Pages 893-906作者：Yang, H.y.; Wang, X.y.; Wang, C.p.

摘要：In this paper, a robust digital image watermarking algorithm is proposed based on fuzzy support vector machine (FSVM) correction. The significant bitplane image is extracted from original host, and undecimated discrete wavelet transform (UDWT) is performed on the significant bitplane image. The lowpass subband is divided into small blocks, and digital watermark is embedded into original host by adaptively modulating the selected wavelet coefficients in small blocks. In order to resist geometric distortion attacks, FSVM is utilized to learn geometric distortion parameters by using low order Zernike moments. The watermark extraction is carried out after watermarked image has been synchronized without original host. Simulation also shows outstanding robustness of the proposed algorithm against most common image processing operations and geometric distortions.

25. 标 题 ： Automated two-dimensional K-means clustering algorithm for unsupervised image segmentation • Article 出处：Computers & Electrical Engineering, Volume 39, Issue 3, April 2013, Pages 907-917作者：Yusoff, I.A.; Mat Isa, N.A.; Hasikin, K. 摘要：This paper introduces the Automated Two-Dimensional K-Means (A2DKM) algorithm, a novel unsupervised clustering technique. The proposed technique differs from the conventional clustering techniques because it eliminates the need for users to determine the number of clusters. In addition, A2DKM incorporates local and spatial information of the data into the clustering analysis. A2DKM is qualitatively and quantitatively compared with the conventional clustering algorithms, namely, the K-Means (KM), Fuzzy C-Means (FCM), Moving K-Means (MKM), and Adaptive Fuzzy K-Means (AFKM) algorithms. The A2DKM outperforms these algorithms by producing more homogeneous segmentation results.

There is, however, little knowledge about cellular mm-wave propagation in densely populated indoor and outdoor environments. Obtaining this information is vital for the design and operation of future fifth generation cellular networks that use the mm-wave spectrum. In this paper, we present the motivation for new mm-wave cellular systems, methodology, and hardware for measurements and offer a variety of measurement results that show 28 and 38 GHz frequencies can be used when employing steerable directional antennas at base stations and mobile devices.

Questions such as how many people are inside a building and their locations are essential. In this paper, an online localization and situation awareness system is presented, called Mobile Urban Situation Awareness System (MUSAS), for gathering and maintaining localization information, to form a common operational picture. The MUSAS provides multiple localization services, as well as visualization of other sensor data, in a common frame of reference. The information and common operational picture of the system is conveyed to all parties involved in the operation, the field team, and people in the command post. In this paper, a general system architecture for enabling localization based situation awareness is designed and the MUSAS system solution is presented. The developed subsystem components and forming of the common operational picture are summarized, and the future potential of the system for various scenarios is discussed. In the demonstration, the MUSAS is deployed to an unknown building, in an ad hoc fashion, to provide situation awareness in an urban indoor military operation.

Botnets, well-organized distributed network attacks, consist of a large number of bots that generate huge volumes of spam or launch Distributed Denial of Service (DDoS) attacks on victim hosts. New emerging botnet attacks degrade the status of Internet security further. To address these problems, a practical collaborative network security management system is proposed with an effective collaborative Unified Threat Management (UTM) and traffic probers. A distributed security overlay network with a centralized security center leverages a peer-to-peer communication protocol used in the UTMs collaborative module and connects them virtually to exchange network events and security rules. Security functions for the UTM are retrofitted to share security rules. In this paper, we propose a design and implementation of a cloud-based security center for network security forensic analysis. We propose using cloud storage to keep collected traffic data and then processing it with cloud computing platforms to find the malicious attacks. As a practical example, phishing attack forensic analysis is presented and the required computing and storage resources are evaluated based on real trace data. The cloud-based security center can instruct each collaborative UTM and prober to collect events and raw traffic, send them back for deep analysis, and generate new security rules. These new security rules are enforced by collaborative UTM and the feedback events of such rules are returned to the security center. By this type of close-loop control, the collaborative network security management system can identify and address new distributed attacks more quickly and effectively.

However, it is argued that fundamental differences between laboratory-based and naturalistic human behavior may exist. Thus, it remains unclear how well the current knowledge of human brain function translates into the highly dynamic real world. While some demonstrated successes in real-world neurotechnologies are observed, particularly in the area of brain-computer interaction technologies, innovations and developments to date are limited to a small science and technology community. We posit that advancements in realworld neuroimaging tools for use by a broad-based workforce will dramatically enhance neurotechnology applications that have the potential to radically alter human-system interactions across all aspects of everyday life. We discuss the efforts of a joint government-academic-industry team to take an integrative, interdisciplinary, and multi-aspect approach to translate current technologies into devices that are

23

truly fieldable across a range of environments. Results from initial work, described here, show promise for dramatic advances in the field that will rapidly enhance our ability to assess brain activity in real-world scenarios.

Cloud services are delivered from data centers located throughout the world. Cloud computing facilitates its consumers by providing virtual resources via internet. General example of cloud services is Google apps, provided by Google and Microsoft SharePoint. The rapid growth in field of “cloud computing” also increases severe security concerns. Security has remained a constant issue for Open Systems and internet, when we are talking about security cloud really suffers. Lack of security is the only hurdle in wide adoption of cloud computing. Cloud computing is surrounded by many security issues like securing data, and examining the utilization of cloud by the cloud computing vendors. The wide acceptance www has raised security risks along with the uncountable benefits, so is the case with cloud computing. The boom in cloud computing has brought lots of security challenges for the consumers and service providers. How the end users of cloud computing know that their information is not having any availability and security issues? Every one poses, Is their information secure? This study aims to identify the most vulnerable security threats in cloud computing, which will enable both end users and vendors to know about the key security threats associated with cloud computing. Our work will enable researchers and security professionals to know about users and vendors concerns and critical analysis about the different security models and tools proposed.

If x is known to be compressible by transform coding with a known transform, and we reconstruct via the nonlinear procedure defined here, the number of measurements n can be dramatically smaller than the size m. Thus, certain natural classes of images with m pixels need only n=O(m1/4log5/2(m)) nonadaptive nonpixel samples for faithful recovery, as opposed to the usual m pixel samples. More specifically, suppose x has a sparse representation in some orthonormal basis (e.g., wavelet, Fourier) or tight frame (e.g., curvelet, Gabor)-so the coefficients belong to an lscrp ball for 0<ples1. The N most important coefficients in that expansion allow reconstruction with lscr2 error O(N1/2-1p/). It is possible to design n=O(Nlog(m)) nonadaptive measurements allowing reconstruction with accuracy comparable to that attainable with direct knowledge of the N most important coefficients. Moreover, a good approximation to those N important coefficients is extracted from

24

the n measurements by solving a linear program-Basis Pursuit in signal processing. The nonadaptive measurements have the character of "random" linear combinations of basis/frame elements. Our results use the notions of optimal recovery, of n-widths, and information-based complexity. We estimate the Gel'fand n-widths of lscrp balls in high-dimensional Euclidean space in the case 0<ples1, and give a criterion identifying near- optimal subspaces for Gel'fand n-widths. We show that "most" subspaces are near-optimal, and show that convex optimization (Basis Pursuit) is a near-optimal way to extract information derived from these near-optimal subspaces

The significance of this work is introducing an agent-based paradigm for constructing software tools and testbeds for cloud resource management. The novel contributions of this work include: 1) developing Cloudle: an agent-based search engine for cloud service discovery, 2) showing that agent-based negotiation mechanisms can be effectively adopted for bolstering cloud service negotiation and cloud commerce, and 3) showing that agent-based cooperative problem-solving techniques can be effectively adopted for automating cloud service composition. Cloudle consists of 1) a service discovery agent that consults a cloud ontology for determining the similarities between providers' service specifications and consumers' service requirements, and 2) multiple cloud crawlers for building its database of services. Cloudle supports three types of reasoning: similarity reasoning, compatibility reasoning, and numerical reasoning. To support cloud commerce, this work devised a complex cloud negotiation mechanism that supports parallel negotiation activities in interrelated markets: a cloud service market between consumer agents and broker agents, and multiple cloud resource markets between broker agents and provider agents. Empirical results show that using the complex cloud negotiation mechanism, agents achieved high utilities and high success rates in negotiating for cloud resources. To automate cloud service composition, agents in this work adopt a focused selection contract net protocol (FSCNP) for dynamically selecting cloud services and use service capability tables (SCTs) to record the list of cloud agents and their services. Empirical results show that using FSCNP and SCTs, agents can successfully compose cloud services by autonomously selecting services.

9.标题：A Computational Approach to Edge Detection作者：Canny, John 出处：Pattern Analysis and Machine Intelligence, IEEE Transactions on Volume: PAMI-8 Issue: 6 Date : Nov. 1986 Page(s): 679 - 698 Digital Object Identifier : 10.1109/TPAMI.1986.4767851 摘 要 ： This paper describes a computational approach to edge detection. The success of the approach depends on the definition of a comprehensive set of goals for the computation of edge points. These goals must be precise enough to delimit the desired behavior of the detector while making minimal assumptions about the form of the solution. We define detection and localization

25

criteria for a class of edges, and present mathematical forms for these criteria as functionals on the operator impulse response. A third criterion is then added to ensure that the detector has only one response to a single edge. We use the criteria in numerical optimization to derive detectors for several common image features, including step edges. On specializing the analysis to step edges, we find that there is a natural uncertainty principle between detection and localization performance, which are the two main goals. With this principle we derive a single operator shape which is optimal at any scale. The optimal detector has a simple approximate implementation in which edges are marked at maxima in gradient magnitude of a Gaussian-smoothed image. We extend this simple detector using operators of several widths to cope with different signal-to-noise ratios in the image. We present a general method, called feature synthesis, for the fine-to-coarse integration of information from operators at different scales. Finally we show that step edge detector performance improves considerably as the operator point spread function is extended along the edge.

Moreover, it is typically crucial to process data on-line as it arrives, both from the point of view of storage costs as well as for rapid adaptation to changing signal characteristics. In this paper, we review both optimal and suboptimal Bayesian algorithms for nonlinear/non-Gaussian tracking problems, with a focus on particle filters. Particle filters are sequential Monte Carlo methods based on point mass (or "particle") representations of probability densities, which can be applied to any state-space model and which generalize the traditional Kalman filtering methods. Several variants of the particle filter such as SIR, ASIR, and RPF are introduced within a generic framework of the sequential importance sampling (SIS) algorithm. These are discussed and compared with the standard EKF through an illustrative example

In order to overcome throughput limitations common to conventional SAR ADCs, several techniques are proposed. First, a flash sub-ADC is utilized to resolve the 5 MSBs quickly prior to SAR sequential decisions of the LSBs. Second, the DAC operation is time-interleaved by a factor of 2, increasing speed while allowing a single comparator to be shared between all DACs. Third, fully on-chip DAC charge redistribution allows the DAC settling time to be improved by more than an order of magnitude compared to conventional techniques. Finally, the ADC is fully self-timed through the use of a replica timer circuit in order to take full advantage

26

of the fast DAC settling and comparator decisions. Despite the increased speed, the ADC consumes only 31.1 mW and occupies a core area of 0.55 mm2.

This paradigm has often been identified with the solutions developed inside the IETF MANET working group, and for this reason it is called the MANET paradigm. However, they do not coincide, and in the last decade they clearly diverged. In this article, we start from the reasons why the MANET paradigm did not have a major impact on computer communications, and we discuss the evolution of the multihop ad hoc networking paradigm by building on the lessons learned from the MANET research. Specifically, we analyze four successful networking paradigms, mesh, sensor, opportunistic, and vehicular networks, that emerged from the MANET world as a more pragmatic application of the multihop ad hoc networking paradigm. We also present the new research directions in the multihop ad hoc networking field: peoplecentric networking, triggered by the increasing penetration of the smartphones in everyday life, which is generating a people-centric revolution in computing and communications.

14.标题：Feature Coding in Image Classification: A Comprehensive Study作者：Yongzhen Huang ; Zifeng Wu ; Liang Wang ; Tieniu Tan 出处：Pattern Analysis and Machine Intelligence, IEEE Transactions on Volume: 36 Issue: 3 Date : March 2014 Page(s): 493 - 506 Digital Object Identifier : 10.1109/TPAMI.2013.113 摘 要 ： Image classification is a hot topic in computer vision and pattern recognition. Feature coding, as a key component of image classification, has been widely studied over the past several years, and a number of coding algorithms have been proposed. However, there is no comprehensive study concerning the connections between different coding methods, especially how they have evolved. In this paper, we first make a survey on various feature coding methods, including their motivations and mathematical representations, and then exploit their relations, based on which a taxonomy is proposed to reveal their evolution. Further, we summarize the main characteristics of current algorithms, each of which is shared by several coding strategies. Finally, we choose several representatives from different kinds of coding approaches and empirically

27

evaluate them with respect to the size of the codebook and the number of training samples on several widely used databases (15-Scenes, Caltech-256, PASCAL VOC07, and SUN397). Experimental findings firmly justify our theoretical analysis, which is expected to benefit both practical applications and future research.

IEEE Computer Society Conference on Volume: 1 Date : 25-25 June 2005 Page(s): 886 - 893 vol. 1 Digital Object Identifier : 10.1109/CVPR.2005.177 摘要：We study the question of feature sets for robust visual object recognition; adopting linear SVM based human detection as a test case. After reviewing existing edge and gradient based descriptors, we show experimentally that grids of histograms of oriented gradient (HOG) descriptors significantly outperform existing feature sets for human detection. We study the influence of each stage of the computation on performance, concluding that fine-scale gradients, fine orientation binning, relatively coarse spatial binning, and high-quality local contrast normalization in overlapping descriptor blocks are all important for good results. The new approach gives near-perfect separation on the original MIT pedestrian database, so we introduce a more challenging dataset containing over 1800 annotated human images with a large range of pose variations and backgrounds.

Baum and T. Petrie (1966) and gives practical details on methods of implementation of the theory along with a description of selected applications of the theory to distinct problems in speech recognition. Results from a number of original sources are combined to provide a single source of acquiring the background required to pursue further this area of research. The author first reviews the theory of discrete Markov chains and shows how the concept of hidden states, where the observation is a probabilistic function of the state, can be used effectively. The theory is illustrated with two simple examples, namely coin-tossing, and the classic balls-in-urns system. Three fundamental problems of HMMs are noted and several practical techniques for solving these problems are given. The various types of HMMs that have been studied, including ergodic as well as left-right models, are described

摘要：This paper presents design techniques for a high power supply rejection (PSR) low drop-out (LDO) regulator. A bulky external capacitor is avoided to make the LDO suitable for system-on-chip (SoC) applications while maintaining the capability to reduce high-frequency supply noise. The paths of the power supply noise to the LDO output are analyzed, and a power supply noise cancellation circuit is developed. The PSR performance is improved by using a replica circuit that tracks the main supply noise under process-voltage-temperature variations and all operating conditions. The effectiveness of the PSR enhancement technique is experimentally verified with an LDO that was fabricated in a 0.18 μm CMOS technology with a power supply of 1.8 V. The active core chip area is 0.14 mm2, and the entire proposed LDO consumes 80 μA of quiescent current during operation mode and 55 μA of quiescent current in standby mode. It has a drop-out voltage of 200 mV when delivering 50 mA to the load. The measured PSR is better than -56 dB up to 4 MHz when delivering a current of 50 mA. Compared to a conventional uncompensated LDO, the proposed architecture presents a PSR improvement of 34 dB and 25 dB at 1 MHz and 4 MHz, respectively.

However, the lack of an open-source metal alternative and the high capital costs and slow throughput of proprietary commercialized metal 3-D printers has severely restricted their deployment. The applications of commercialized metal 3-D printers are limited to only rapid prototyping and expensive finished products. This severely restricts the access of the technology for small and medium enterprises, the developing world and for use in laboratories. This paper reports on the development of a open-source metal 3-D printer. The metal 3-D printer is controlled with an open-source micro-controller and is a combination of a low-cost commercial gas-metal arc welder and a derivative of the Rostock, a deltabot RepRap. The bill of materials, electrical and mechanical design schematics, and basic construction and operating procedures are provided. A preliminary technical analysis of the properties of the 3-D printer and the resultant steel products are performed. The results of printing customized functional metal parts are discussed and conclusions are drawn about the potential for the technology and the future work necessary for the mass distribution of this technology.

In the field of data conversion, standard analog-to-digital converter (ADC) technology implements the usual quantized Shannon representation - the signal is uniformly sampled at or above the

29

Nyquist rate. This article surveys the theory of compressive sampling, also known as compressed sensing or CS, a novel sensing/sampling paradigm that goes against the common wisdom in data acquisition. CS theory asserts that one can recover certain signals and images from far fewer samples or measurements than traditional methods use.

摘要：The use of distributed energy resources is increasingly being pursued as a supplement and an alternative to large conventional central power stations. The specification of a power-electronic interface is subject to requirements related not only to the renewable energy source itself but also to its effects on the power-system operation, especially where the intermittent energy source constitutes a significant part of the total system capacity. In this paper, new trends in power electronics for the integration of wind and photovoltaic (PV) power generators are presented. A review of the appropriate storage-system technology used for the integration of intermittent renewable energy sources is also introduced. Discussions about common and future trends in renewable energy systems based on reliability and maturity of each technology are presented

However, with an explosion of wireless mobile devices and services, there are still some challenges that cannot be accommodated even by 4G, such as the spectrum crisis and high energy consumption. Wireless system designers have been facing the continuously increasing demand for high data rates and mobility required by new wireless applications and therefore have started research on fifth generation wireless systems that are expected to be deployed beyond 2020. In this article, we propose a potential cellular architecture that separates indoor and outdoor scenarios, and discuss various promising technologies for 5G wireless communication systems, such as massive MIMO, energy-efficient communications, cognitive radio networks, and visible light communications. Future challenges facing these potential technologies are also discussed.

This technique is used iteratively to assign these nodes ID numbers ranging from 1 to N. This assignment is anonymous in that the identities received are unknown to the other members of the group. Resistance to collusion among other members is verified in an information theoretic sense when private communication channels are used. This assignment of serial numbers allows more complex data to be shared and has applications to other problems in privacy preserving data mining, collision avoidance in communications and distributed database access. The required computations are distributed without using a trusted central authority. Existing and new algorithms for assigning anonymous IDs are examined with respect to trade-offs between communication and computational requirements. The new algorithms are built on top of a secure sum data mining operation using Newton's identities and Sturm's theorem. An algorithm for distributed solution of

31

certain polynomials over finite fields enhances the scalability of the algorithms. Markov chain representations are used to find statistics on the number of iterations required, and computer algebra gives closed form results for the completion rates.

3. 会议名称：I3D '14—ACM SIGGRAPH Symposium on Interactive 3D Graphics and Games会议时间：March 14 - March 16 2014 会议地点：San Francisco CA USA会议简介： I3D is the leading conference for real time 3D computer graphics and human interaction.2014 marks the 28th year since the first conference. This time we will go to San Francisco, California during March 14th-16th (Friday-Sunday). We invite you to submit papers across the entire range of topics in interaction, interactive 3D graphics, and games.I3D 2014 will be held in San Francisco, California. Additionally, The Game Developers Conference (GDC'14) will be held right after I3D in the Bay Area making it an excellent opportunity to attend both conferences.For 2014, the I3D conference is partnering with the Journal of Computer Graphics Techniques to allow accepted JCGT papers to be presented at I3D and select I3D papers to be published as extended versions in JCGT. This brings together the advantages of a journal and a conference, allowing both considered, detailed exploration of a topic without page limits and public presentation and debate. JCGT and I3D are a good fit for one another, with overlapping communities and a shared focus on practical, robust methods with collaboration between academia and industry.I3D Paper Followup in JCGT: Every paper accepted at I3D will automatically be considered by the I3D committee and JCGT board for subsequent followup in the journal. Authors of papers that are recommended for followup in JCGT will have the opportunity to revise at least 30% of their paper to address the implementation details, limitations, and robustness evaluation emphasized by the journal. At least two of the anonymous I3D reviewers from the original paper will also review for JCGT per paper, providing continuity and accelerating the publication process. The papers selected for this process will be announced at the I3D closing ceremony.JCGT Papers Presented at I3D: The authors of any paper submitted to JCGT before 22 October 2013 who want to present at I3D 2014 should e-mail managing-editor@jcgt.org before 4 December 2013. In the event that there are more authors who wish to take advantage of this opportunity than the schedule can accomodate, we will prioritize speaking slots in the order that e-mails were received. Authors whose papers are under review may request a slot conditional on their paper being accepted. Speakers must register for and attend the conference as would authors presenting papers in the regular I3D program.This partnership is in addition to the partnership I3D has had with the IEEE Transactions on Visualization and Graphics (TVCG) where TVCG papers can be presented at I3D and the best I3D papers will be invited to submit extended versions to appear in a TVCG special issue.

5. 会议名称：MMSys '14会议时间：March 19 - March 21 2014 会议地点：Singapore Singapore会议简介：Background of MMSysThe inaugural MMSys was held in Scottsdale, Arizona on February 22-23, 2010. It's history and creation are detailed below.MMSys HistoryWe believe it is important to have a full, top-tier conference that focuses specifically on multimedia systems research. We want to reach out to those researchers who primarily identify themselves as part of more "traditional" systems communities such as networking, operating systems, databases, and real-time systems but for whom multimedia applications are a driving problem. The conferences in each of these separate systems communities routinely contain tracks and sessions for multimedia-driven research. That our field has been so widely integrated back into these other communities is, in fact, a testament to the success of SIG Multimedia as a community. What was missing, however, was a longitudinal view of multimedia systems research that cut across these traditional system boundaries. While the systems track of our flagship conference ACM Multimedia helps to serve in this role, participation by multimedia systems researchers who are not SIGMM members has not been as strong as we would like. By holding a conference that concentrates on these systems issues, we are hoping to better target the research interests of these communities of researchers. Hopefully we can also inspire them to value and participate in the even broader holistic view that our flagship conference provides.We should note that great care has been taken to plan how MMSys relates to existing conferences and workshops. In particular, the plan is for MMSys to replace MMCN held each January as part of SPIE's Electronic Imaging (EI). While MMCN has served our community well in the past, several severe weaknesses were beginning to take their toll. MMCN is the only EI sub-conference that required full paper submissions and had a competitive acceptance rate. The other EI sub-conferences are abstract-only submissions with reasonably high acceptance rates. Increasingly this became problematic as people familiar with the other sub-conferences assumed that MMCN was also a high-acceptance rate, abstract-only meeting. Junior faculty, in particular, were constantly having to educate tenure review committees about how MMCN was different. Furthermore,

34

MMCN is not indexed by or incorporated into the ACM Digital Library.After having had great success with MMSys in 2010, 2011, and 2012, MMSys has fully established itself and is ready to grow again. In particular, the colocation of MMSys 2012 and the MoVid 2012 workshop proved to be quite successful and the executive committees for both events have agreed to make this association permanent going forward. Furthermore, we are excited to add the NOSSDAV workshop as a permanently co-located event starting in 2013. NOSSDAV (http://www.nossdav.org) is one of the longest running workshops in multimedia computing with an illustrious history of fostering early work-in-progress and exciting "out of the box" ideas and research directions. This constellation of meetings are all sponsored by SIGMM and thus enjoy the benefits of the digital library and access to SIG Services. Each component will retain its own independent program committee and will be published within the digital library as a distinct and separate proceeedings. This will allow each of the three events to retain its focus and culture while providing significant logistical benefits to both organizers and participants.论文提交：http://www.mmsys.org/

题 目 :DEVICE CHARACTERISTICS OF A 10.1% HYDRAZINE-PROCESSED CU2ZNSN(SE,S)4 SOLAR CELL 作者:BARKHOUSE DAR; GUNAWAN O; GOKMEN T; TODOROV TK; MITZI DB 出处:PROG PHOTOVOLTAICS 20 (1): 6-11 JAN 2012 摘要:A power conversion efficiency record of 10.1% was achieved for kesterite absorbers, using a Cu2ZnSn(Se,S)4 thin-film solar cell made by hydrazine-based solution processing. Key device characteristics were compiled, including light/dark JV, quantum efficiency, temperature dependence of Voc and series resistance, photoluminescence, and capacitance spectroscopy, providing important insight into how the devices compare with high-performance Cu(In,Ga)Se2. The record kesterite device was shown to be primarily limited by interface recombination, minority carrier lifetime, and series resistance. The new level of device performance points to the significant promise of the kesterites as an emerging and commercially interesting thin-film technology. Copyright (c) 2011 John Wiley & Sons, Ltd.

These processes are based on the transfer of the oxygen from air to the fuel by means of a solid oxygen-carrier avoiding direct contact between fuel and air for different final purposes. CLC has arisen during last years as a very promising combustion technology for power plants and industrial applications with inherent CO2 capture which avoids the energetic penalty present in other competing technologies. CLR uses the chemical looping cycles for H-2 production with additional advantages if CO2 capture is also considered. The review compiles the main milestones reached during last years in the development of these technologies regarding the use of gaseous or solid fuels, the oxygen-carrier development, the continuous operation experience, and modelling at several scales. Up to 2010, more than 700 different materials based on Ni, Cu, Fe, Mn, Co, as well as other mixed oxides and low cost materials, have been compiled. Especial emphasis has been done in those oxygen-carriers tested under continuous operation in Chemical-Looping prototypes. The total time of operational experience ( approximate to 3500 h) in different CLC units in the size range 0.3-120 kW(th), has allowed to demonstrate the technology and to gain in maturity. To help in the design, optimization, and scale-up of the CLC process, modelling work is also reviewed. Different levels of modelling have been accomplished, including fundamentals of the gas-solid reactions in the oxygen-carriers, modelling of the air-and fuel-reactors, and integration of the CLC systems in the power plant. Considering the great advances reached up to date in a very short period of time, it can be said that CLC and CLR are very promising technologies within the framework of the CO2 capture options.

This is the highest efficiency reported for pure sulfide Cu2ZnSnS4 prepared by any method. Consistent with literature, the optimal composition is Cu-poor and Zn-rich despite the precipitation of secondary phases (e.g., ZnS). Despite a very thin absorber thickness (similar to 600 nm), a reasonably good short-circuit current was obtained. Time-resolved photoluminescence measurements suggest a minority carrier-diffusion length on the order of several hundreds of nanometers and relatively good collection of photo-carriers across the entire absorber thickness.

Our attention is focused on the design of full-and reduced-order filters that guarantee the filtering error system to be asymptotically stable with a prescribed H-infinity performance. Sufficient conditions for the obtained filtering error system are proposed by applying an input-output approach and a two-term approximation method, which is employed to approximate the time-varying delay. The corresponding full-and reduced-order filter design is cast into a convex optimization problem, which can be efficiently solved by standard numerical algorithms. Finally, simulation examples are provided to illustrate the effectiveness of the proposed approaches.

It is well known that carbonaceous support materials suffer from carbon corrosion (oxidation) especially at high potentials over time and thus alternative low-cost, high-performing and non-corrosive electrocatalyst support materials are urgently required. This review highlights the performance and issues associated with a variety of carbon based materials such as carbon nanotubes (CNT), carbon nanofibers (CNF), mesoporous carbon and graphene as well as non-carbonaceous based materials, e.g. titania, indium oxides, alumina, silica and tungsten oxide and carbide, ceria, zirconia nanostructures and conducting polymers catalyst support materials. Comparisons and advantages and disadvantages of the various supports are clearly described in this review. (C) 2012 Elsevier B.V. All rights reserved.

It has been widely applied to signal processing, computer vision, and data mining. Traditional NMF solvers include the multiplicative update rule (MUR), the projected gradient method (PG), the projected nonnegative least squares (PNLS), and the active set method (AS). However, they suffer from one or some of the following three problems: slow convergence rate, numerical instability and nonconvergence. In this paper, we present a new efficient NeNMF solver to simultaneously

45

overcome the aforementioned problems. It applies Nesterov's optimal gradient method to alternatively optimize one factor with another fixed. In particular, at each iteration round, the matrix factor is updated by using the PG method performed on a smartly chosen search point, where the step size is determined by the Lipschitz constant. Since NeNMF does not use the time consuming line search and converges optimally at rate O(1/k(2)) in optimizing each matrix factor, it is superior to MUR and PG in terms of efficiency as well as approximation accuracy. Compared to PNLS and AS that suffer from numerical instability problem in the worst case, NeNMF overcomes this deficiency. In addition, NeNMF can be used to solve L-1-norm, L-2-norm and manifold regularized NMF with the optimal convergence rate. Numerical experiments on both synthetic and real-world datasets show the efficiency of NeNMF for NMF and its variants comparing to representative NMF solvers. Extensive experiments on document clustering suggest the effectiveness of NeNMF.

The aim is to consider the bounded L-2 gain performance in the analysis of sliding mode dynamics, thus to improve the transient performance of the SMC system. Firstly, a delay-dependent bounded real lemma is proposed for the underlying system to be stochastically admissible while achieving the prescribed bounded L-2 gain performance condition. An integral-type switching surface function is designed by taking the singular matrix into account, thus the resulting sliding mode dynamics is a full-order singular Markovian jump time-delay system. Then the sliding mode dynamics is analyzed and the solvability condition for the desired switching surface function is derived. Moreover, an SMC law is synthesized to drive the system trajectories onto the predefined switching surface in a finite time. Finally, a numerical example is provided to illustrate the effectiveness of the proposed techniques. (C) 2012 Elsevier Ltd.

ISS. SI APR 2012 摘 要 :Due to the simplicity of their implementations, least square support vector machine (LS-SVM) and proximal support vector machine (PSVM) have been widely used in binary classification applications. The conventional LS-SVM and PSVM cannot be used in regression and multiclass classification applications directly, although variants of LS-SVM and PSVM have been proposed to handle such cases. This paper shows that both LS-SVM and PSVM can be simplified further and a unified learning framework of LS-SVM, PSVM, and other regularization algorithms referred to extreme learning machine (ELM) can be built. ELM works for the "generalized" single-hidden-layer feedforward networks (SLFNs), but the hidden layer (or called

46

feature mapping) in ELM need not be tuned. Such SLFNs include but are not limited to SVM, polynomial network, and the conventional feedforward neural networks. This paper shows the following: 1) ELM provides a unified learning platform with a widespread type of feature mappings and can be applied in regression and multiclass classification applications directly; 2) from the optimization method point of view, ELM has milder optimization constraints compared to LS-SVM and PSVM; 3) in theory, compared to ELM, LS-SVM and PSVM achieve suboptimal solutions and require higher computational complexity; and 4) in theory, ELM can approximate any target continuous function and classify any disjoint regions. As verified by the simulation results, ELM tends to have better scalability and achieve similar (for regression and binary class cases) or much better (for multiclass cases) generalization performance at much faster learning speed (up to thousands times) than traditional SVM and LS-SVM.

The Takagi-Sugeno (T-S) fuzzy model approach is adapted in this study with the consideration of the sprung and the unsprung mass variation, the actuator delay and fault, and other suspension performances. By the utilization of the parallel-distributed compensation scheme, a reliable fuzzy H-infinity performance analysis criterion is derived for the proposed T-S fuzzy model. Then, a reliable fuzzy H-infinity controller is designed such that the resulting T-S fuzzy system is reliable in the sense that it is asymptotically stable and has the prescribed H-infinity performance under given constraints. The existence condition of the reliable fuzzy H-infinity controller is obtained in terms of linear matrix inequalities (LMIs) Finally, a quarter-vehicle suspension model is used to demonstrate the effectiveness and potential of the proposed design techniques.

作者:SARATHY SM; VRANCKX S; YASUNAGA K; MEHL M; OSSWALD P; METCALFE WK; WESTBROOK CK; PITZ WJ; KOHSE-HOINGHAUS K; FERNANDES RX; CURRAN HJ 出处:COMBUST FLAME 159 (6): 2028-2055 JUN 2012 摘要:Alcohols, such as butanol, are a class of molecules that have been proposed as a bio-derived alternative or blending agent for conventional petroleum derived fuels. The structural isomer in traditional "bio-butanol" fuel is 1-butanol, but newer conversion technologies produce iso-butanol and 2-butanol as fuels. Biological pathways to higher molecular weight alcohols have also been identified. In order to better understand the combustion chemistry of linear and branched alcohols, this study presents a comprehensive chemical kinetic model for all the four isomers of butanol (e.g., 1-, 2-, iso- and tert-butanol). The proposed model includes detailed high-temperature and low-temperature reaction pathways with reaction rates assigned to describe the unique oxidation features of linear and branched alcohols. Experimental validation targets for the model include low pressure premixed flat flame species profiles obtained using molecular beam mass spectrometry (MBMS), premixed laminar flame velocity, rapid compression machine and shock tube ignition delay, and jet-stirred reactor species profiles. The agreement with these various data sets spanning a wide range of temperatures and pressures is reasonably good. The validated chemical kinetic model is used to elucidate the dominant reaction pathways at the various pressures and temperatures studied. At low-temperature conditions, the reaction of 1-hydroxybutyl with O-2 was important in controlling the reactivity of the system, and for correctly predicting C-4 aldehyde profiles in low pressure premixed flames and jet-stirred reactors. Enol-keto isomerization reactions assisted by radicals and formic acid were also found to be important in converting enols to aldehydes and ketones under certain conditions. Structural features of the four different butanol isomers leading to differences in the combustion properties of each isomer are thoroughly discussed. (C) 2011 The Combustion Institute.

Several recent studies have shown that declining rates of evaporative demand are primarily governed by trends in the aerodynamic component (primarily being the combination of the effects of wind speed (u) and atmospheric humidity) and secondarily by changes in the radiative component. A number of these studies also show that declining rates of observed near-surface u (termed 'stilling') is the primary factor contributing to declining rates of evaporative demand. One objective of this paper was to review and synthesise the literature to assess whether stilling is a globally widespread phenomenon. We analysed 148 studies reporting terrestrial u trends from across the globe (with uneven and incomplete spatial distribution and differing periods of measurement) and found that the average trend was -0.014 m s(-1) a(-1) for

48

studies with more than 30 sites observing data for more than 30 years, which confirmed that stilling was widespread. Assuming a linear trend this constitutes a -0.7 m s(-1) change in u over 50 years. A second objective was to confirm the declining rates of evaporative demand by reviewing papers reporting trends in measured pan evaporation (E-pan) and estimated crop reference evapotranspiration (ETo); average trends were -3.19 mm a(-2) (n = 55) and -1.31 mm a(-2) (n = 26), respectively. A third objective was to assess the contribution to evaporative demand trends that the four primary meteorological variables (being u; atmospheric humidity; radiation; and air temperature) made. The results from 36 studies highlighted the importance of u trends. We also quantified the sensitivity of rates of evaporative demand to changes in u and how the relative contributions of the aerodynamic and radiative components change seasonally over the globe. Our review: (i) shows that terrestrial stilling is widespread across the globe; (ii) confirms declining rates of evaporative demand; and (iii) highlights the contribution u has made to these declining evaporative rates. Hence we advocate that assessing evaporative demand trends requires consideration of all four primary meteorological variables (being u, atmospheric humidity, radiation and air temperature). This is particularly relevant for long-term water resource assessment because changes in u exert greater influence on energy-limited water-yielding catchments than water-limited ones.

Based on simulations, we show that the semipolar (20 (2) over bar(1) over bar) orientation exhibits excellent potential for the development of high-efficiency, low-droop light-emitting diodes (LEDs). We then present recent advancements in crystal growth, optical performance, and thermal performance of semipolar (20 (2) over bar(1) over bar) LEDs. Finally, we demonstrate a low-droop, high-efficiency single-quantum-well blue semipolar (20 (2) over bar(1) over bar) LED with an external quantum efficiency of more than 50% at 100 A/cm(2).

Thus wind power forecasting plays a key role in dealing with the challenges of balancing supply and demand in any electricity system, given the uncertainty associated with the wind farm power output. Accurate wind power forecasting reduces the need for additional

49

balancing energy and reserve power to integrate wind power. Wind power forecasting tools enable better dispatch, scheduling and unit commitment of thermal generators, hydro plant and energy storage plant and more competitive market trading as wind power ramps up and down on the grid. This paper presents an in-depth review of the current methods and advances in wind power forecasting and prediction. Firstly, numerical wind prediction methods from global to local scales, ensemble forecasting, upscaling and downscaling processes are discussed. Next the statistical and machine learning approach methods are detailed. Then the techniques used for benchmarking and uncertainty analysis of forecasts are overviewed, and the performance of various approaches over different forecast time horizons is examined. Finally, current research activities, challenges and potential future developments are appraised. (C) 2011 Elsevier Ltd. All rights reserved.

In this hybrid the alpha-MnO2 nanowires are well entangled with MWCNTs. The MWCNTs provide a network for fast electron transport whereas MnO2 nanowires show a fast redox response. Since gain/loss of both electrons and ions can be realized very rapidly at the same time, the hybrid has an excellent rate capability and delivers an energy density of 17.8 Wh kg(-1) at 400W kg(-1), which is maintained almost constant even at 3340W kg(-1) in 0.5 M Li2SO4 aqueous electrolyte. The cycling behavior is very good even in the presence of oxygen. The data present great promise for the hybrid as a practical cathode material for aqueous supercapacitor. (C) 2011 Elsevier B.V.

The time-varying system (target plant) is subject to randomly varying nonlinearities (RVNs) caused by environmental circumstances. The lossy sensor network suffers from quantization errors and successive packet dropouts that are described in a unified framework. Two mutually independent sets of Bernoulli distributed white sequences are introduced to govern the random occurrences of the RVNs and successive packet dropouts. Through available output measurements from not only the individual sensor but also its neighboring sensors according to the given topology, a sufficient condition is established for the desired distributed finite-horizon filter to ensure that the prescribed average filtering performance constraint is satisfied. The solution of the distributed filter gains is characterized by solving a set

50

of recursive linear matrix inequalities. A simulation example is provided to show the effectiveness of the proposed filtering scheme.
