Average ber of multihop communication systems over fading channels
(
IEEE
, 2003 , Conference Paper)
Multihop transmission is a way to attain broader coverage by splitting the communication link from the source to the destination into several, possibly shorter links/hops. This paper presents an expression for the moment ...
Power loading algorithms for SEC diversity schemes
(
IEEE
, 2007 , Conference Paper)
Switch and Examine Combing (SEC) diversity scheme is one of the simplest diversity schemes to combat fading. When the power used for probing the channels in this scheme is fixed, it can be higher than what is actually ...
On hybrid-fuzzy classifier design: An empirical modeling scenario for corrosion detection in gas pipelines
(
IEEE
, 2008 , Conference Paper)
In this paper, a customized Fuzzy Inference System is presented to classify the corrosion and distinguish it from the geometric defects or normal state of the steel pipes used in gas/petroleum industry. The presented ...
Predicting transformers oil parameters
(
IEEE
, 2009 , Conference Paper)
In this paper different configurations of artificial neural networks are applied to predict various transformers oil parameters. The prediction is performed through modeling the relationship between the transformer insulation ...

As the number of mobile phone users is growing, purchasing products and services using mobile phones and other mobile devices are also increasing. The purpose of this study was to provide the status of mobile-commerce in ...
Semantic Map Based Web Search Result Visualization
(
IEEE
, 2007 , Conference Paper)
The problem of information overload has become more pressing with the emergence of the increasingly more popular Internet services. The main information retrieval mechanisms provided by the prevailing Internet Web software ...
A new closed-loop converter for sinusoidal encoders - Preliminary results
(
IEEE
, 2009 , Conference Paper)
Sinusoidal position transducers provide accurate and reliable representation of the mechanical position of their shafts. The sine/cosine transducers signals may be used in open loop or closed loop arrangements for the ...
Digital control for UPS inverters
(
IEEE
, 2003 , Conference Paper)
PWM inverters digital controls with dead-beat re sponse, for UPS applications, are reviewed. To improve the output waveforms of the PWM inverter, several modern control techniques are applied together with the deadbeat ...

A resolver converter based upon a novel open-Loop Technique
(
IEEE
, 2008 , Conference Paper)
The paper presents a novel technique for the determination of the angle from slowly-varying quadrature co-sinusoidal signals produced, for example, by position sensors. In the presented scheme applied to a resolver, the ...
