On the capacity of cooperative diversity systems with adaptive modulation
(
IEEE
, 2005 , Conference Paper)
In recent years, cooperative diversity systems have gained increased attention in the literature as a new way of combating the effect of signal fading. In this paper, we investigate the performance of these systems when ...
Measuring the quality of earnings
(
Emerald
, 2005 , Article)
Purpose - Although the academic research on the quality of earnings has been improved by presenting different approaches of measurement, there is no agreed-upon generally accepted approach to measure the earning quality. ...

On multistage ranked set sampling for distribution and median estimation
(
Elsevier B.V.
, 2007 , Article)
A variation of ranked set sampling (RSS), multistage RSS (MSRSS), is investigated for the estimation of the distribution function and some of its quantiles, in particular the median. It is shown that this method is ...
Interestingness filtering engine: Mining Bayesian networks for interesting patterns
(
Elsevier Ltd
, 2009 , Article)
In this paper, we present a new measure of interestingness to discover interesting patterns based on the user’s background knowledge, represented by a Bayesian network. The new measure (sensitivity measure) captures the ...

The prevalence of allergic diseases such as asthma, allergic rhinitis and atopic dermatitis have risen at an alarming rate throughout the world in the past 50 years. Sensitization to food (FA) and inhalant allergens (IA) ...
Assessing Quality of Web Based Systems
(
IEEE
, 2008 , Conference Paper)
This paper proposes an assessment model for Web-based systems in terms of non-functional properties of the system. The proposed model consists of two stages: (i) deriving quality metrics using goal-question-metric (GQM) ...
A novel multilevel carrier-based PWM-control method for GTO inverter in low index modulation region
(
IEEE
, 2006 , Article)
Gate turn offs (GTOs) have an inherent minimum ON-OFF time, which is needed for their safe operation. For GTO-based three-level or neutral-point-clamped (NPC) inverters, this minimum ON-OFF pulsewidth limitation results ...
Stemming Versus Light Stemming as Feature Selection Techniques for Arabic Text Categorization
(
IEEE
, 2007 , Conference Paper)
This paper compares and contrasts two feature selection techniques when applied to Arabic corpus; in particular; stemming, and light stemming were employed. With stemming, words are reduced to their stems. With light ...
