Title:
Smart ZV and the Innovation Cycle
Abstract
Everyone dreams of being an inventor. To create something new that did not exist before and in the process, add value to the company. But how does it actually happen? Is it really as simple as a light bulb coming on in someone’s head with a new novel idea? Patrick Flanders will share his experience with the development of new instrumentation and control devices that demonstrated success had more to do with struggle than inspiration. Without the struggle, the inspiration was not possible. He describes the process as the Innovation Cycle. It demonstrates how we all can experience the excitement of innovation if we are willing to move from the comfort zone of tried and proven solutions.

Title
1: Analytical Techniques for the Design and Performance Evaluation
of Diversity Systems over Fading Channels
Abstract 1
Many of the current and emerging wireless communication technologies and systems make use of some form of diversity combining to combat the fading and shadowing effects induced by the harsh, complex, and dynamic channel. In designing such systems to achieve a specified quality of service, one is also faced with the practical reality of satisfying a predetermined degree of complexity. Thus, although the optimum (from a performance standpoint) diversity combining techniques such as maximal-ratio combining (MRC) (for coherent systems) and equal gain combining (EGC) (for non-coherent and differentially-coherent systems) are well-known, one often opts in favor of a less complex scheme at a sacrifice in performance.
In this tutorial a wide variety of receiver, transmitter, and MIMO diversity combining schemes are outlined and compared from a performance and complexity standpoint. The analytical tools used to obtain the performance of these systems are also be presented and discussed. The mathematical formalism is illustrated by various parametric performance curves that can help researchers and design engineers to perform trade-off studies among various diversity combining schemes so as to determine the most suitable choice in the face of their available constraints. The tutorial concludes with discussions of combining in diversity rich environments which is a recent application that has seen a great deal of interest and progress over the last couple of years.

Title
2: Extreme Bandwidth Communications: Opportunities, Challenges, and
Some Solutions
Abstract 2
The tremendous improvement of wireless communication technologies lead to a growing demand for a variety of applications with super-high data rate requirement. However, it is very difficult to deploy these new services in the currently crowded frequency bands. Hence, it is natural to consider the utilization of some unused wideband frequency bands. As such solutions are being currently developed to support 2 to 5 Gbits/sec applications on the millimeter
(mm) band (57~64 GHz). In addition the demand for much higher data rate is expected to increase in order to meet the extreme bandwidths requirements of Ultra High Definition TV broadcasting, 3D image transmission, inter vehicle communications, and super-high speed WLAN.
It is threfore natural to start thinking of the design of communications systems for the 10 to 40 GBits/sec services which are thought to be realizable over the unused Tera Hertz (THz) band (i.e; sub-mm (< 1mm) spectrum beyond 100 GHz).
This talk goes over the potential offered by 60 GHz (mm) and THz (sub-mm) communications and then summarizes the main challenges that need to be overcome before such systems can be deployed. The talk finally concludes with a summary of some of the low-complexity solutions explored in the presenter research group to support super-high data rate in these high bands.
Dr. Mohamed Slim Alouini was born in Tunisia in 1969. He received the Diplome d'Ingenieur from the École Nationale Supérieure des Télécommunications, Paris, France, and the Diplome d'Etudes Approfondies (D.E.A.) in Electronics from the Université Pierre et Marie Curie, both in 1993.

He also received the Habilitation Degree from the Université Pierre et Marie Curie in 2003.
Dr. Mohamed-Slim Alouini started his academic career at the department of Electrical and Computer Engineering of the University of Minnesota in 1998. In 2005, he joined the Electrical and Computer Engineering Dept. at Texas A&M University in Qatar, where his research interests included statistical characterization and modeling of fading channels, performance analysis of diversity combining techniques, MIMO and multi-hop/cooperative communications systems, capacity and outage analysis of multiuser wireless systems subject to interference or jamming, and design and performance evaluation of multi-resolution, hierarchical, and adaptive modulation schemes.
Starting from June 2009, Dr. Alouini has been appointed Professor of Electrical Engineering in the Division of Physical and Chemical Sciences and Engineering at KAUST, Saudi Arabia.
He will be responsible for research and teaching in communication theory and applied probability.

Title:
Electrohydrodynamic
flow in wire-duct Electrostatic Precipitators
Abstract
Preliminary results of a numerical
and experimental analysis of the electrohydrodynamic (EHD) flow associated with wire-duct electrostatic precipitators is presented. The finite element method (FEM) and a modified method of characteristics are combined to solve the governing equations. In addition, an experimental set-up that represents a WDEP has been designed and fabricated. The experimental set-up makes it possible to vary the number and diameter of wires, wires-to-wire spacing and wire-to plate spacing as well as the flow speed. Comparing the present computed results with previously obtained experimental and calculated values tests the effectiveness of this approach. The agreement with previous experimental and computed results is found to be satisfactory

Title:
Are
Microwave Ovens not (not Safe)?!
Abstract
While few people would dispute
the convenience of microwave ovens, consumers are sometimes concerned about the
safety of microwaves and effect of their radiations. Radiation leakage not only
possesses a hazard to the human health but also interfere with the ISM
(industrial, scientific, and medical) band. WiFi, Bluetooth, in addition to
some cordless phones are among the important technologies that could be
directly impacted by microwave oven radiation. Industrial plants are among the
affected sectors.
While there are mature
standards to control the emission and leakage of microwave ovens, the
performance of commercial microwave ovens is questionable?!
The objective of this
presentation is NOT to encourage/discourage the use of microwave ovens but
rather to increase the awareness by illustrating the variation of radiation
leakage under different conditions. Examined scenarios include:

Title:
Nondestructive Testing from Black Smith Profession to Advanced High Tech Profession
Abstract
Considerable advancement in research and development in the last few decades has enabled non-destructive testing (NDT) to change from a ‘‘Black Smith’’ profession to an advanced multidisciplinary High Tech. engineering profession. This has led to cost effective solutions of many challenging problems. Pipelines for instance, can now be screened without disturbing the production using intelligent tools such as pigging, guided wave ultrasound, phased arrays, etc. In addition, the existence of cheap computing capabilities has led to the development of NDT techniques that are now becoming operator independent.
In this seminar, I will give an overview of NDT techniques since “the Stone time” and propagate it through time until today’s latest state of the art instrumentations and methods. I will also brief the opportunities and benefits one gets in working in such a challenging field.

Title:
Monitoring of Arc Welding
using Laser and Diode Illumination Sources: a Novel Approach
Abstract
A revolutionary low-cost vision system is presented based on the use of a low-cost laser diode to illuminate the weld area in the presence of an intense arc. The design features and the specification of the different components that make up the system are detailed. A combination of optical filtering, short pulse laser diode illumination and fast-shuttering imaging techniques along with precise synchronisation and very accurate triggering methods has enabled high quality images of the weld area irrespective of the presence of intense arc brightness and the usage of a low-cost CMOS camera. It has been found that laser diodes provide an extremely efficient and economic alternative illumination system to the bulky and expensive laser systems usually adopted. Some high power laser diodes can produce a pulsed output power of up to 210W, which means that a cluster of just a few laser diodes will produce enough peak power to illuminate the weld pool. Laser diodes have a narrow spectral width, hence we have used a narrow band pass filter to cut most of the arc light allowing only light from the laser diodes to pass through to the camera. It is also shown that lasers are much powerful illumination sources and produce high quality images. However, they are expensive and bulky to use.

Title:
Joint Probing and Scheduling in Wireless
Communications Systems
Abstract
With the huge demand for high speed packet access
applications and due to the scarcity of the available spectrum new advance and
robust techniques that help utilize the bandwidth efficiently and provide high
bit-rates are being investigated extensively by researchers. One technique that
has the capability of supporting such applications is multiuser diversity
(MUDiv), where the fading of channels is exploited. Assume that a reasonably
large number of users are actively transmitting/receiving packets in a given
cell, and they experience independent time-varying fading conditions. By
transmitting data to only the instantaneous ”on-peak” user, opportunistic
scheduling (OS) can efficiently utilize the wireless resources and thus
dramatically improve the overall system throughput. It has been shown that the
total capacity (uplink and downlink) can be maximized by picking the user with
the best channel to transmit. In multiuser wireless system, in order to
schedule the best user, in terms of channel quality, the network scheduler
probes each user, requesting his instantaneous signal-to-noise ratio (SNR).
While this method leads to the best user, it will result a high delay
scheduling process and an inefficient usage of the spectrum resources. In this
work we study joint probing and scheduling algorithms for opportunistic
spectrum access. The work was conducted while visiting the

Title:
Design of Expanded Constellations for PAPR
Reduction in OFDM Systems
Abstract
The demand for wireless channel and high data rate is
increasing. However, such channel under such requirement is very harsh and
causes multipath fading resulting in inter-symbol-interference (ISI). One of
the best solution employed in such environment is orthogonal frequency division
multiplexing (OFDM) system. However, OFDM systems suffer from the high peak to
average power ratio (PAPR) causing inefficient usage of the high power
amplifier (HPA). There are many techniques used to reduce the high PAPR. These
techniques trade off complexity, data rate, signal power, and bit error rate
(BER) to reduce the high PAPR of the transmitted OFDM signal.
In this seminar we introduce OFDM systems. Its advantages, applications, and problems are highlighted. Then, we propose a new method for PAPR reduction in OFDM systems. The method benefits from a novel constellation design and an innovative utilization of erasure codes. The complementary cumulative distribution function (CCDF) of the modified OFDM signals shows PAPR reduction in the range of 5 dB at a clipping probability of 10-4 over the original OFDM signals.
