Autonomous corrosion detection in gas pipelines: A hybrid-fuzzy classifier approach using ultrasonic nondestructive evaluation protocols
(
IEEE
, 2009 , Article)
In this paper, a customized classifier is presented for the industry-practiced nondestructive evaluation (NDE) protocols using a hybrid-fuzzy inference system (FIS) to classify the corrosion and distinguish it from the ...
Operational modeling of multistream heat exchangers with phase changes
(
Wiley Subscription Services, Inc., A Wiley Company
, 2009 , Article)
Multistream heat exchangers (MSHE) enable the simultaneous exchange of heat among multiple streams, and are preferred in cryogenic processes such as air separation and LNG. Most MSHEs are complex; proprietary and involve ...
A Resolver Angle Estimator Based on Its Excitation Signal
(
IEEE
, 2009 , Article)
A resolver generates a pair of signals proportional to the sine and cosine of the angular position of its shaft. A new low-cost method for converting the amplitudes of these sine/cosine transducer signals into a measure ...

(
جامعة الأزهر - كلية أصول الدين و الدعوة بالزقازيق
, 2009 , Article)
تسهم الخدمات التطوعية بدور كبير في بناء كثير من الحضارات و المجتمعات على مر العصور. حيث انها لا تمثل مهنة وبصفتها عملاً خالياً من الربح يقوم به مجموعة من الأفراد من اجل الغير. وتأخذ أشكالا وانماطاً متعددة منها الذاتية ومنها ...
Attracting High Achieving Secondary Students through Early Admission Call-Up in an American Style College in Lebanon: A Comparison with American Colleges
(
National Association for College Admission Counseling
, 2009 , Article)
An early admission call-up was used to attract high-achieving students to a private university in Lebanon. The callup,
which is essentially an offer of admission before the student takes any formal steps, was administered ...
Complex-impedance response of an Ag/TeO2-V2O5/Ag structure
(
Elsevier
, 2009 , Article)
The ac conductivity of glass samples of composition 50 mol% TeO2 and 50 mol% V2O5 has been analyzed. The samples were prepared by the usual melt-quench method. The electrical conductance and capacitance were measured over ...
A simulated annealing technique for multi-objective simulation optimization
(
Elsevier
, 2009 , Article)
In this paper, we present a simulated annealing algorithm for solving multi-objective simulation optimization problems. The algorithm is based on the idea of simulated annealing with constant temperature, and uses a rule ...
Efficient Channel Allocation Scheme with Triangle Communication
(
IEEE
, 2009 , Article)
Radio is a valuable resource for wireless/mobile communication systems. In this paper, we present an efficient algorithm using a novel triangle communication model to synchronize processes effectively by searching for free ...
Controlling Error Propagation in Network-Coded Cooperative Wireless Systems
(
IEEE
, 2009 , Article)
In cooperative communications, error propagation at relays degrades the diversity order of the system. To combat that effect, it has been suggested to implement a reliability threshold at the relay to control error ...
Quality assurance considerations in chemical analysis
(
John Wiley & Sons, Ltd.
, 2009 , Article)
Quality Assurance (QA) for an analytical laboratory is an essential tool to ensure good comparability of data. In order to achieve this purpose, processes are monitored and performance problems are systematically solved. ...
