Chair's Message This is my last contribution to the departmental newsletter as department chair. It has been an exciting 13 years since I came to Denton and assumed leadership of the department. During that time the electronics, manufacturing, and nuclear programs were accredited. In addition, the mechanical design program converted to mechanical engineering technology and received accreditation. Recently, the construction program was reinstated to accommodate industry demands with accreditation a goal in the next three years.

The graduate program has evolved into the leading program in the country for engineering technology. Students complete a project or thesis solving very sophisticated applications problems mostly sponsored by industry. Cooperating with the College of Business masters degrees in technology management are offered. In addition, students may complete a joint degree program resulting in both a BSET and MBA.

I have worked for two presidents, three provosts and five deans. The department has been in two colleges and in two physical locations. What has not changed has been the support and hard work of the faculty and staff. The progress made in the past thirteen years would not have been possible without their effort and dedication.

The programs have fully transitioned from industrial technology in the College of Arts and Sciences to engineering technology in the College of Engineering. Facilities are vastly improved from a building on the main campus with over 300 drafting tables, upholstery equipment, woodworking laboratories and two computers, to a modern facility in the Research Park occupying a 55000 sq. ft. wing of the Engineering Research Park. Hundreds of computers interconnected through local and internet networking, contemporary design software, numerically controlled manufacturing equipment, state of the art structures research facilities, materials analysis and electronics testing and system development equipment are now the stock and trade of the program.

The achievements of the graduates are impressive. Some have gone on to graduate school and advanced degrees in engineering or business. Some are enjoying success in industry utilizing the skills and knowledge gained in an applications oriented curriculum to move ahead in their fields. Graduates from the accredited programs may become registered professional engineers in Texas.

The major focus now needs to shift to expectations of faculty performance. Still in progress is the transition from faculty primarily engaged in teaching classes to faculty also engaged in the practice of engineering through externally funded grants and projects. All new faculty members are required to hold the PhD in engineering with some industrial experience. Professional registration is expected. Full participation in the area of scholarly activity is required for tenure and promotion. An existing cadre of faculty are meeting that challenge and will establish new models for engineering technology faculty nationally.

The next chair will have an opportunity to lead the department to even greater levels than present. I wish him/her and the faculty well as they take the department and programs to new levels for engineering technology. I am proud of the accomplishments experienced by the department thus far, and look forward to observing its continuing development as a national leader in engineering technology and applications engineering.

To paraphrase an old general, old department chairs never die, they just fade away!

Propagation Analysis of a 900 MHz Short Path Spread Spectrum

Centralized Traffic Signal Control System

This thesis research reports the propagation analysis and modeling of a 900 MHz, short path, spread spectrum, centralized traffic signal control system. The traffic signal controls at intersections in the City of Denton, Texas were examined.

Eleven sites were constructed and signal strengths from the selected sites monitored. Analysis was performed for the large city, urban, small city, semi-rural, and rural forms of the Okumura-Hata model. The statistical data analysis shows that Okumura-Hata's Suburban and Semi-rural models can be used to predict signal strength for the City of Denton's 900 MHz spread spectrum, traffic signal control system.

derivative (DNA base) deposited between gold electrodes. The electrodes are lithographically designed on a GaN substrate separated by a distance. The electrical and optical properties of such wide-bandgap semiconductor based biomaterial systems were studied and evaluated for their potential application as detectors. The current-voltage characteristics, Photocurrent Spectroscopy and Photo-luminescence of the resulting device were measured in order to study the semiconducting properties of such devices. The measurement of the photocurrent spectroscopy also provided estimates of the bandgap of the guanosine derivative.

FEM of Nanoindentation on Micro- and Nano-crystalline Ni: Analysis of

Factors Affecting Hardness and Modulus Values

Raja Mahesh Pothapragada

Nanoindentation is a widely used technique to measure the mechanical properties of films with thickness ranging from nanometers to micrometers. A much better understanding of the contact mechanics is obtained mostly through finite element modeling.

Indentation experiments were conducted and pileup was calculated by directly measuring the dimensions of the residual impression by AFM techniques. The fundamental material properties affecting pileup are the ratio of the effective modulus to yield stress and the work hardened behavior. Two separate cases of work hardening rates were considered; one with no work hardening rates and the other with a linear work hardening rate.

When pileup occurs the contact area is greater than that predicted by the experimental methods and both the hardness and modulus are overestimated. Tip bluntness often leads to the misinterpretation of the Load-displacement data.

Comparison of these simulated results with experimental results demonstrated that the continuum based finite element approach has the capability to determine the load-depth response of an indentation test. The experiments were modeled using the software package Nano SPI that is based on COSMOS/M, a finite element code.

Indoor Propagation Modeling at 2.4 GHz for IEEE 802.11 Networks

Dinesh Tummala

Indoor use of wireless systems poses one of the biggest design challenges. It is difficult to predict the propagation of a radio frequency wave in an indoor environment. To assist in deploying the above systems, characterization of the indoor radio propagation channel is essential. The contributions of this work are two-fold. First, in order to build a model, extensive field strength measurements were carried out inside two different buildings. Then, path loss exponents from Log-distance Path Loss Model and standard deviations from Log-Normal Shadowing, which statistically describe the path loss models for different transmitter receiver separations and scenarios, were determined.

The purpose of this study was to characterize the indoor channel for 802.11 wireless local area networks at 2.4 GHz frequency. This thesis presents a channel model based on measurements conducted in commonly found scenarios in buildings. These scenarios include closed corridor, open corridor, classroom, and computer lab. Path loss equations are determined using Log-distance Path Loss Model and Log-Normal Shadowing. The Chi-square test statistic values for each access point were calculated to prove that the observed fading is a normal distribution at 5% significance level. Finally, the propagation models from the two buildings were compared to validate the generated equations.

TXU Update

Dr. Mitty Plummer

TXU renewed its contract with UNT in December 2005 to deliver courses to power plant personnel at the Comanche Peak Steam Electric Station for the 17th year. The program continues with substantial participation despite a reduced number of employees at the site.

An on-site graduation ceremony is planned for May 2006. This ceremony will possibly include the first graduate from the plant with high honors and two graduates with honors.

Engineering Technology Department Equipped With an

ESEM Dr. Seifollah Nasrazadani

Dr. Nasrazadani acquired an Environmental Scanning Electron Microscope (ESEM) which is capable of imaging wet samples. Conventional SEMs require samples to be fully dried and vacuum compatible that are not desirable for transient processes taking place on the surfaces which need to be investigated. This microscope has nanometer resolution and is expected to greatly enhance Seifollah's research capabilities. This microscope is equipped with hot and cold (Peltier) stages which facilitate morphological examination of nano surfaces at temperatures ranging from subzero to 1500oC.

NUET Industrial Advisory Board Meeting

December 19, 2005

The Nuclear Engineering Technology Industrial Advisory Board met to discuss matters related to ABET accreditation, curriculum revisions based on the upcoming addition of a two hour ethics course, and a reduction in curriculum to 120 hours starting in 2008. The Board decided that most of the reduced hours could be taken from technical electives.

The departmental proposal to increase the senior project to four hours was not approved by the committee and it was strongly suggested that the senior project remain as two hours in the final semester. The remaining two hours would be the College required ethics course.

The Board acknowledged plans for 2006 based on a reduced budget.

ELET Industrial Advisory Board Meeting

November 11, 2005

In addition to the electronics faculty, representatives from the following companies and institutions participated: Texas Instruments, Federal Aviation Administration, Dallas Semiconductor and FreeScale Semiconductor.

Dr. Vijay Vaidyanathan made a presentation on the state of the program. Sixty-percent of the graduates have a 3.0 GPA or higher. Graduate students include 4 theses and 15 non-theses. Computer Engineering uses 5 of our undergraduate and 1 graduate courses and Electrical Engineering uses 3 of our undergraduate courses.

Our students are serving internships with FAA, Littlefuse, Sanmina, Nokia, and Dallas Semiconductor. Recent graduates have been employed with Peterbilt and FAA. We have graduates pursuing advanced degrees at Duke, Penn State, and UTD.

Student presentations were delivered by Nergis Soylemez, Christian Winter, Lonnie Langle and Chris Borne. Faculty members Shuping Wang and Elias Kougianos led open discussions.

An idea was brought forth to have a UNT Day. Invite selected industry representatives to UNT to discuss research interests and capabilities of UNT faculty. Industry reps can present emerging research interests which are at a different level than IAB members who tend to be managers. Have student competition as defined by industry and evaluated by industry reps. Sell what distinguishes UNT ETEC from other technology programs and their students.

A lab tour and Freescale presentation concluded the meeting. The curriculum is on track and proposed changes were viewed favorably by the IAB members.

• A High power, 635 nm laser that can be used for Photodynamic Therapy applications.

• Beam analyzers and power meters that can be used to characterize and profile laser beams for various applications.

New VLSI Laboratory

Dr. Elias Kougianos

Dr. Kougianos is co-founder, along with Dr. Saraju P. Mohanty of the Computer Science and Engineering Department, of the VLSI Design and CAD Laboratory that forms the core of the Computer Engineering and VLSI efforts at the College of Engineering. Since its inception in 2005, two graduate students have successfully defended their master's theses while eight additional students are working on Ph.D.'s and master's projects.

The lab's research centers on low-power VLSI design for nanoscale CMOS architectures for multimedia algorithms and advanced techniques for the design and simulation of low-power, high-performance analog, mixed signal and RF integrated circuits. In little more than a year, the laboratory has attracted international attention with the receipt of the 2005 DAC award, numerous publications by students and researchers, and has participated in several joint research proposals - two of which are under consideration by NSF, one by the Texas ARP and one by Texas Instruments. A major collaborative effort is under way with two universities in Taiwan and is expected to result in additional NSF proposals.

College Awarded $24,000 for Integrated Circuit Design

Oscar Garcia, Founding Dean of the College of Engineering, said this award is an honor from a well-established national conference: the Design Automation Conference. "I would like to congratulate our Engineering Technology faculty member, Elias Kougianos and his student Rahul Allawadhi."

Dr. Kougianos said the one-year, $24,000 graduate scholarship awarded to UNT will allow him and Allawadhi to modify and enhance the original Berkeley code and make it more appropriate for today's high-speed, high-performance integrated circuit designs. "This effort is the starting point for the development of a robust and nationally known research program in the wider area of Electronic Design Automation."

Mr. Allawadhi's project is titled SPICE Modernization. SPICE (Simulation Program with Integrated Circuit Emphasis) has been the main tool used in the design of integrated circuits since its original development at the University of California, Berkeley. Today, practically every integrated circuit design center uses SPICE or one of its commercial variants during the integrated circuit development process. Rahul said he is excited and eager to work on the project under the guidance of Dr. Kougianos and Dr. Saraju Mohanty of Computer Science and Engineering.

Job Well Done!

Congratulations to Administrative Assistant Rebecca Wright for 25 years service to UNT and to Dr. Robert Hayes for 10 years.

Dr. Phillip Foster, Dr. Seifollah Nasrazadani and Mr. Charles Bittle were each awarded a Certificate of Appreciation by the Dean's Office for their activities during Engineering Week.

Surface Plasmon Based Nanophotonic Optical Emitters

Padmarekha Vemuri

Semiconductor materials play a vital role in opto-electronics and high-speed digital circuits for applications in computers and telecommunications. Ultraviolet light emitting diodes (LED) are expected to find numerous applications in diverse field such as biotechnology, medicine, home security and solid-state lighting. Surface plasmons are essentially light waves that are trapped on the surface of the emitting device, because of their interaction with free electrons of the conductor. This research project pursued the design and development of a noble metal photonic system for enhancing the emission property of UV light, for potential use in nanophotonic UV emitters and detectors.

The enhancement of emission was accomplished by depositing layers of different metals, with different thicknesses, on a Gallium Nitride semiconductor surface. The deposition was carried out using sputtering and metal evaporation techniques. Periodic patterns were fabricated on metal films using Focused Ion Beam Lithography. Surface characterization of metal films was performed using X-ray Photoelectron Spectroscopy and Scanning Electron Microscopy. These characterizations included measurement of photoluminescence and electro luminescence, respectively. Statistical analysis was performed using mean separation procedures and student's t-tests to explain the effect of deposition and characterization techniques on light emission. A significant enhancement in light emission was observed using the noble-metal photonic system.

New MFET/MEET Laboratories

The last bastion of Engineering Technology on the UNT main campus was transferred to the Research Park (RP) during the months of July and August, 2005. The new facilities, which nearly double the space formerly available at the old location, have allowed a much more comfortable and safe working environment for students and faculty.

Four new labs were constructed. The General Access Design (GAD) Lab easily accommodates 20 workstations and boasts reserve space for another 16. New computers with 19” LCD displays grace the

GAD lab. A new Fluids Lab was constructed at the east end of the ETEC wing. It includes amenities such as an eyewash station, a sink and cabinet area, and a spacious storage closet. The lab is also plumbed for a laboratory exhaust hood system. Contiguous with the Fluids Lab is the Thermal Sciences Lab, also with similar amenities. The spacious floor plans of these two MEET labs will easily accommodate the Division's increasing enrollment and that projected for the years ahead.

Perhaps the most spectacular new lab is that housing Manufacturing Processes and Mechanical Testing. The facility is designed with minimal interior walls; the two exterior walls are virtually glass, floor to ceiling, and provide beautiful views of the countryside. Hardware/Equipment is clustered by process, e.g., machining, plastics, welding, testing. Clusters are designated by large letters painted on the 12’-high walls. Up to four distinct classes can be conducted simultaneously affording students an opportunity to “look ahead” at what they will be doing in future semesters. The floor plan has the appearance of a “Factory of the Future”; the ceilings are open displaying a multitude of color coded-utilities. Concrete floors are painted battleship gray; corridors are defined by yellow safety lines. An integrated tool crib is utilized by all clusters and students have a small meeting room for their “management teams” in various courses.

The new MFET/MEET labs have become a common tour destination for visitors to the College of Engineering. Come take a look for yourself.

Status of Construction Labs

The first phase of the NUCONSTEEL Structural Testing Lab is complete. New light fixtures have been installed, the electrical wiring is complete and the lab is isolated with cages. An office was built in the new testing lab.

A 12-foot high 16-foot span structural reaction frame was finished in February 2005. The reaction frame is equipped with a MTS 35 kips hydraulic actuator and a hydraulic pump. The reaction frame is capable of conducting full scale bending tests, compression tests, and shear wall tests. Simpson donated an Anchor System for the reaction frame.

A 22-foot high, 30-foot span, 2-ton bridge crane was installed for the construction lab. Four 22-foot deep underground piers were constructed to support the crane.

TXU donated a potable 3-ton crane. The gift was arranged by Mr. Iven Vogelsang, Manager of Electrical Engineering. The crane is the first operational equipment in the lab and is used to construct heavy steel frames for structural testing.

The lab development is entering phase two. A 60-foot long and 20-foot high Truss testing fixture is being built for light gauge steel and wood truss testing. The interior and exterior doors are being enlarged for future passage of trusses.
