Dr. Salah Al-Din Burhan Al Omari

is from Jordan, and was born in the

city of Zarqaa in 1966. He is

married, and a father of three sons

and a daughter, and lives in the

United Arab Emirates in Al Ain

city. He is Associate Professor and

the Chairman of the Department of

Mechanical Engineering at UAEU.

Dr. Salah lived in Zarqaa under the

care of his parents who have

aspired for him to become

successful in his life one day and to

fulfill his goals with complete

satisfaction. Dr. Salah has

explained how reading in his

younger years has affected his

personality and character in a

dramatic way where he had learned

about different majors of literature

and science, and studied the

biographies of the most famous

scientists like Isaac Newton and

Thomas Edison. This was the

reason behind his persistence and

devotion of knowledge and

success. He used to enjoy a

delightful time of reading in the

weekend that had its distinctive

taste of amusement.

Dr. Salah finished his secondary

education at the School of Muaawiya ibn

Abi Sufyan in after which his inclination

to engineering has gradually grew and so

decided to complete his undergraduate

studies at Jordan University of Science

and Technology in northern Jordan

majoring in mechanical engineering

where he received his bachelor's degree

in 1988. Dr. Salah continued his graduate

studies at in the University of Jordan in

the field of heat transfer which lasted

two years and a half. He then moved to

Japan in 1991 to work on some research

and during his stay there he, won a

scholarship to complete his doctoral

studies at the University of Aachen in

Germany which lasted about five years

after which he graduated with a doctorate

in Mechanical Engineering in 1997

majoring in the area of Spray

Combustion. Dr. Salah highlights that the

beautiful memories and times he spent in

Germany are noteworthy and

unforgettable. He mentions a memory

where upon graduation people close to

you and Colleagues at the university

have the habit of making a festive

ceremony of their own, such as

accompanying the graduates across the

city with distinctive ceremonial

uniforms.

Apart from personal matters, the talk

about engineering matters started;

specifically about Mechanical

Engineering at the United Arab

Emirates University. Dr. Salah pointed

out that the Mechanical Engineering

Department at UAEU has its own

honored position compared to other

universities both on the local and

international scale. Also, it is featured

in terms of scientific and academic

research and aspires to always be

distinctive, and to continue

development in many aspects. For

example, the teaching process is

considered to completely elaborate

which gives the chance for students to

receive the knowledge in the best way

they deserve, besides the constant

quest for the development of the

laboratory equipment to ever meet

highest level of excellence possible.

Speaking on the faculty and the

system used in the department, Dr.

Salah praised the effort made by the

existing competencies from whom he

is expecting to further raise the

general level as well as the basis for

the functioning of the educational

process as a whole.

It is considered by Dr. Salah that the

procedures followed at the

Department, supported by the

management of UAEU, is of a high

efficiency and meets global

standards and bear the challenges of

the future with a high-quality output.

Dr. Salah sees that the current

generation is surrounded by

enhanced technologies that can be

exploited in positive ways that allow

them to release the energies of their

mental potential. He stressed on the

importance of using technology in a

helpful way and the significance of

the introduction of technology into

educational processes as long as they

are exploited properly in ways that

benefit us. He also pointed out that

mechanical engineers are very

needed now in unlimited spectrum of

industries including of course the

new industries that opened recently

in UAE dealing with aerospace.

These will open new horizons

especially to mechanical engineers.

Noting that, these industries, in

addition to others, have already

existing supporting partnership with

the Mechanical Engineering

Department at UAEU.

In conclusion, Dr. Salah stated that

mechanical engineering and the other

engineering specialties in the United

Arab Emirates are is major of the

elements of the development taking

place in UAE at the present and will

continue to be so in the future. He also

assures that all the necessary and

modern ingredients are available in

the ME study plan for the students and

it is their duty to consider working for

their country with their full potential

in order to cope up with new trends

and technologies emerging in the

world.

flashes through dialogue:

The Mechanical Engineering is one

of the branches of engineering which

have the potential to open wider

horizons than others.

Credibility in expressing any topic is

compulsory no matter the

consequences.

The workmanship at work is one of

the most important priorities during

the work assigned to me and is a part

of my personality Dr. Salah Said.

Mechanics point of view:

When a person attempts to move,

nerve signals are sent from the brain to

the muscles via Moto neurons, moving

the musculoskeletal system as a

consequence. At this moment, very

weak bio signals can be detected on the

surface of the skin. "HAL" catches

these signals through a sensor attached

on the skin of the wearer. Based on the

signals obtained, the power unit is

controlled to move the joint in unison

with the wearer's muscle movement,

enabling HAL to support the wearer's

daily activities. This is what we call a

'voluntary control system' that provides

movement interpreting the wearer's

intention from the bio signals in

advance of the actual movement.

"HAL" is the world's first cyborg-type

robot controlled by this unique Hybrid

System. "HAL" is expected to be

applied in various fields such as

rehabilitation support and physical

training support in medical field, ADL

support for disabled people, heavy

labor support at factories, and rescue

support at disaster sites, as well as in

the entertainment field.

Hybrid Assistive Limb:

(also known as HAL) is a powered

exoskeleton suit developed by

Japan's Tsukuba University and the

robotics company CYBERDYNE.

It has been designed to support and

expand the physical capabilities of

its users, particularly people with

physical disabilities. There are two

primary versions of the system:

HAL 3, which only provides leg

function, and HAL 5, which is a

full-body exoskeleton for the arms,

legs, and torso. HAL 5 is capable of

allowing the operator to lift and

carry about five times as much

weight as he or she could lift and

carry unaided. 1s

An oscilloscope, previously

called an oscillograph, and

informally known as

a scope, CRO (for cathode-ray

oscilloscope), or DSO (for the

more modern digital storage

oscilloscope), is a type

of electronic test instrument that

allows observation of constantly

varying signal voltages, usually

as a two-dimensional graph of

one or more electrical potential

differences using the vertical

or y-axis, plotted as a function of

time (horizontal or x-axis). Many

signals can be converted to

voltages and displayed this way.

Signals are often periodic and

repeat constantly so that multiple

samples of a signal which is

actually varying with time are

displayed as a steady picture.

Many oscilloscopes (storage

oscilloscopes) can also capture

non-repeating waveforms for a

specified time and show a steady

display of the captured segment.

Oscilloscopes are commonly used

to observe the exact wave

shape of an electrical signal.

Oscilloscopes are usually

calibrated so that voltage and time

can be read as well as possible by

the eye. This allows the

measurement of peak-to-peak

voltage of a waveform, the

frequency of periodic signals, the

time between pulses, the time

taken for a signal to rise to full

amplitude (rise time), and relative

timing of several related signals.

Oscilloscopes are used in the

sciences, medicine, engineering,

and telecommunications industry.

General-purpose instruments are

used for maintenance of

electronic equipment and

laboratory work. Special-purpose

oscilloscopes may be used for

such purposes as analyzing an

automotive ignition system or to

display the waveform of the

heartbeat as an electrocardiogram.

Some computer sound software

allows the sound being listened to

be displayed on the screen as by

an oscilloscope.

Before the advent of digital electronics oscilloscopes

used cathode ray tubes as their display element (hence were

commonly referred to as CROs) and linear amplifiers for signal

processing. More advanced storage oscilloscopes used special

storage CRTs to maintain a steady display of a single brief

signal. CROs were later largely superseded by digital storage

oscilloscopes (DSOs) with thin panel displays, fast analog-to-

digital converters and digital signal processors. DSOs without

integrated displays (sometimes known as digitisers) are available

at lower cost and use a general-purpose digital computer to

process and display waveforms.

As a part of Mechanical

Engineering program’s objectives

and outcomes that were set by

UAE university, we should be able

to use software that will help us in

designing different systems which

will allow us to success in our

future job especially in industries.

ANSYS FLUENT is one of these

important software that thousands

of companies are using nowadays.

It is mainly used to fulfil many

industrial applications like

modelling a flow, turbulence, heat

transfer and reactions. For example,

it allows us to build our physical

system to simulate a desired flow

like the flow over an aircraft wing.

We, as an ASME team, decided to

conduct a workshop in ANSYS

FLUENT software since it is

required to be used in some courses

like Fluid Mechanics and Heat

Transfer and thus it will give a big

benefit for the students who are

taking these courses or even

graduation projects students.

The workshop was held on

Tuesday 24th September 2013

from 7:00 to 9:00 pm in

measurements lab in E6 building.

It was decided to be given by me

and I chose to explain an example

of how to simulate a flow between

two parallel plates starting from

building the geometry, choosing

the mesh, preparing the setup and

finally ending with getting many

results as numbers, contours and

plots. There were about 40

students who attended the

workshop;. It was the first time for

me to be an instructor for this

number of students but I enjoyed

it and it was done successfully. In

my opinion, the main demerit of

having a big number of students is

exceeding the scheduled time for

the workshop due to the difficulty

of controlling them and it will take

more time to follow up with the

students one by one to make sure

that they have done all the steps in

a right way. In general, students

who attended the workshop said

that they gained a big benefit from

it and heat transfer course students

suggested to have more advanced

workshop that may satisfy their

needs more.

One of the most remarkable events since the beginning of the current semester was

the Mechanical Engineering sports day, held at UAEU Maqam sports complex.

From organizing point of view, me as being held responsible for the event faced no

trouble managing anything, it all went smooth contacting all the responsible parties.

The day started off at 7 o’clock in the afternoon, gathering all the students by the

soccer court. Batches were divided according to their interest whether soccer,

tennis or table tennis. However, soccer as usual attracts the most number of

students; we had 6 teams, each team consists of 6 members. Teams’ names entered

a draw and teams competed, until we had two final teams fighting for the first

place. Besides this, we had 10 table tennis players and 3 tennis players. After three

hours of continuous effort, it was time to chill with the faculty members and my

colleagues, where delicious food and beverages were served for everyone while

exchanging conversations. At the end, I’d like to thank all my ASME mates who

shared in organizing this wonderful event, and special thanks to Dr. Mohamed

Hamdan, the ASME supervisor. In addition to this, ASME appreciates the presence

of all who showed up, whether from the faculty members or ME students. And on

the behalf of my team, we promise you with more such great events, and looking

forward for the honor of everyone’s presence.

System Dynamics Lab is one of the main courses in Mechanical

Engineering. The lab aims to provide students with a full understanding

and detailed hands-on skills of dynamic systems analysis and control

implementation. The lab consists of two main experiments based on

representative thermal, fluid, and mechanical systems. The Goal of

Experiment 1 (ball-in-tube) is to find the relationship between the

actuator input and the process output in the form of transfer function. It

is the relationship between blower input voltage and ball height. We

learned how to derive the differential equations, how to linearize the

nonlinear equations and how to convert them to Laplace transformed

equations. In this experiment, we used a MATLAB program to deal with

the transformed equations. We used (cftool) and we learned in details

about fitting and smooth data fitting.

In this experiment it was a very interesting one where we learned many

things that we in fluid lecture memorize but really we did not know what

it is in real life, and that why the labs lectures are very important since

they really show you the laws physically in front of you and also give us

the chance to be scientist to validate laws that are well known. Let’s get

back to our experiment where the main reason behind it was Measure

velocity distribution in a pipe and that was the first objective I mean for

part a of the experiment where as for the second part was about Measure

the pressure drop in a circular tube at different Re. Measure the pressure

drop in the entrancer egion and the laminar and turbulent flow. Compare

the results with available experimental results. And below a images

taken while doing the experiment.

The first experiment we have run in

the design and manufacturing lab was

about “ball joints”. Many of human

body joints can be classified as ball

joints, for example, the knee joints.

The purpose of a ball joint is to act as

a pivot. It gives a wide range of

rotation. Ball joints work with the

suspension to allow the car to navigate

the road smoothly. Without them you

would have a very bumpy ride. In the

lab, the experiment was divided into

three sections. Firstly, a traditional

method using “lathe machine” was

used to produce a ball joint. All

students tried this themselves taking

into accounts all the safety

requirements. Our instructor Dr. Basel

believes that students should interact

with the machines and equipments and

they should try something with their

hands to feel the real engineering.

Actually, all students were interested

in doing that and they noticed how

using this method takes very much

time.

Secondly, students were asked to

design a tool that could help us

producing a ball joint using a lathe

machine. The best design will be

manufactured later on. Finally, we

moved to a more modern machine

“NCC machine” to see how

producing a ball joint could be much

easier than before. NCC machine is a

numerically controlled machine that

does many operations like turning

and milling. By the help of the lab

engineer, we learnt how to use this

machine to produce a ball joint and

also we realized the importance of

the new technology in

manufacturing. Surely, new

technology and programmed

machines make our life easier.

Thanks the human’s brain!!
