Research ArticleOpen accessIn the author namesAn Adjustable Sample Size Estimation Model for Usability AssessmentHaidar S. Jabbar, T.V. Gopal, Sattar J. AboudUsability assessment plays a fundamental role in discovering usability problems and the determination of the level of usability for a given software product. One crucial aspect in every usability assessment is the estimation of the sample size desired for a software product. Once we start estimating the sample size needed for a usability assessment, a baffling question comes in mind: … …American Journal of Applied Sciences, Vol. 4, Issue 8 · 31 Aug 2007 · 6,967 accessesView PDFCite
Research ArticleOpen accessIn the author namesA Different Text Attack Algorithm in Integer Factoring Based SchemesMohammed A. AL-Fayoumi, Sattar J. Aboud, Musbah M. AqelText attack in integer factoring based schemes is generally calculated as an intrinsic characteristic of its symmetric attack. In this article, we illustrate that asymmetric integer factoring based schemes are also vulnerable to a text attack. Also, we show that a single message is required to increase a successful text attack versus the Lucas scheme. …Journal of Computer Science, Vol. 3, Issue 6 · 30 Jun 2007 · 6,659 accessesView PDFCite

Research ArticleOpen accessIn the author namesMagnetic Properties and Electrical Resistivity of Zr4+ Substituted Li-Zn FerriteA. A. Sattar, H. M. El-Sayed, W. R. Agami, A. A. GhaniThe effect of Zr-substitution on the physical and magnetic properties of Li0.3+0.5xZn0.4ZrxFe2.3-1.5xO4 ferrites (x=0.0, 0.01, 0.02, 0.03 and 0.05), prepared by the standard ceramic method, has been studied. It is found that the saturation magnetization increases up to x=0.02 and then it decreases. On the other hand, the initial permeability increased while the Curie temperature remained almost constant with increasing … …American Journal of Applied Sciences, Vol. 4, Issue 2 · 28 Feb 2007 · 8,349 accessesView PDFCite
