Defect Deconvolution using 4th Order Statistics for Ultrasonic Nondestructive Testing
(
IEEE
, 2007 , Conference Paper)
Classification of defects using ultrasonic nondestructive testing (NDT) is primarily done in the field of industrial materials to provide useful information in order to assist in making administrative decisions in terms ...
The State of Qatar Informative Web Portal
(
IEEE
, 2008 , Conference Paper)
This paper describes the electronic government project in the state of Qatar known as Qatar Central Government Portal (Hukoomi e-Gov). It highlights the main online services that are offered to Qataris citizens and residents. ...
Performance enhancement of relay-assisted communications via binary feedback
(
IEEE
, 2004 , Conference Paper)
This paper proposes a modified two-hop wireless communication system and studies its performance. The modified system has a reliable feedback channel that carries a binary signal from the receiver to inform the transmitter ...
Iterative learning control for variable frequency drives
(
IEEE
, 2008 , Conference Paper)
Variable Frequency Drives (VFD) are subject to various types of disturbances especially cyclical ones. These periodic disturbances are difficult to compensate by conventional controllers. Repetitive control can only ...
Effects of Post and Early Selection on SEC Based Transmit Diversity Systems with Linear Power Loading
(
IEEE
, 2008 , Conference Paper)
Switch and examine combing (SEC) diversity scheme provides a lowest-complexity closed-loop transmit diversity solution. Furthermore, by probing sequentially available branches with different power loading levels, the SEC ...
Fuzzy mapping of human heuristics for defect classification in gas pipelines using ultrasonic NDE
(
IEEE
, 2007 , Conference Paper)
This paper presents a methodology for classifying the common defects in steel pipelines for transporting petroleum and gas. Usually, the nondestructive evaluation (NDE) experts in the industry judges the defect type by ...

(
IEEE
, 2008 , Conference Paper)
This research aims at to assess the impact of natural hazards on the human activities and development planning held along the eastern coastal stretch of the Gulf of Suez. Change detection technique was used in combined ...
Chip-Level Modulated BPPM Fiber-Optic Code Division Multiple Access
(
IEEE
, 2009 , Conference Paper)
Chip-Level Modulated Binary Pulse Position Modulation (CLM-BPPM) is proposed as a modulation scheme for Fiber-Optic Code Division Multiple Access (FO-CDMA) systems using Optical Orthogonal Code (OOC) for time domain signal ...
Ion beam modification of surface properties of polyethylene
(
Elsevier
, 2003 , Conference Paper)
Improvement of polymer tribological properties is an essential issue for their application when used as parts of machines or artificial human joints. Ion implantation is a very promising technique in this respect. This ...
Wireless application deploying cell broadcast, and bulk SMS/MMS
(
International Business Information Management Association, IBIMA
, 2009 , Conference Paper)
Cell broadcast is a mobile technology that allows messages to be broadcast to all mobile handsets and similar devices within a designated geographical area. The broadcast range can be varied, from a single cell to the ...
