Research ArticleOpen accessIn the abstractThe Biology of p21Waf1/Cip1 - Review PaperRenald A. Blundellp21WAF1/Cip1 belongs to the Cip/Kip family of cyclin kinase inhibitors (CKI) (p21Waf1/Cip1, p27Kip1, p57Kip1). p21Waf1/Cip1 was first described as a potent and universal inhibitor of cyclin-dependent kinases (Cdks). Two forms of functionally active p21 has been localized and described: a nuclear and a cytoplasmic forms. In this paper the structures of p21 has been described and as well as it … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 1 · 31 Mar 2006 · 7,018 accessesView PDFCite
Research ArticleOpen accessIn the abstractDatComNet: Designing an Intelligent Visual Tool for Teaching Data Communication and Network Information SystemsAbdel B. Salem, Ibrahiem M.M. El Emary, Hussain F. SindiDatComNet is a tutorial tool designed to assist students in understanding the concepts of designing, implementing and managing the data communication networks. It is particularly useful for computer science and computer engineering students in computer communication network courses. The DatComNet interface is written in C++ and clips. The use of Java as the language of implementation provides platform independent access … …Journal of Computer Science, Vol. 2, Issue 2 · 28 Feb 2006 · 6,923 accessesView PDFCite
Research ArticleOpen accessIn the abstractEstimation of the COCOMO Model Parameters Using Genetic Algorithms for NASA Software ProjectsAlaa F. ShetaDefining the project estimated cost, duration and maintenance effort early in the development life cycle is a valuable goal to be achieved for software projects. Many model structures evolved in the literature. These model structures consider modeling software effort as a function of the developed line of code (DLOC). Building such a function helps project managers to accurately allocate the … …Journal of Computer Science, Vol. 2, Issue 2 · 28 Feb 2006 · 9,364 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Online Website for Tutoring and E-Examination of Economic CourseIbrahiem M.M. EL Emary, Jihad A.A. Abu Al SondosThis study aimed to present a novel software tool can be used for online examination and tutorial application of the syllabus of economic course. Also, among the main interests of this paper is to produce a software through it we make sure that students have studied all the concepts of economics. So, the proposed software is structured from two major … …American Journal of Applied Sciences, Vol. 3, Issue 2 · 28 Feb 2006 · 6,808 accessesView PDFCite
Research ArticleOpen accessIn the abstractManaging a High Speed LAN using Distributed Artificial IntelligenceIbrahiem M. M-El-EmaryThis study is concerned with a practical application of distributed artificial intelligence for managing the high data rate bus structured local area computer network that uses deterministic multiple access protocol. In the selected network that is managed using distributed artificial intelligence, the dynamic sharing of the available bandwidth among stations is achieved by forming "train to which each station may … …Journal of Computer Science, Vol. 2, Issue 1 · 31 Jan 2006 · 6,989 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Experimental Study of Petty Corrupt Behaviour in Small Decision Making ProblemsTakemi FujikawaThis research discusses small decision making problems and petty corruption as their practical applications with a structured economic experiment. One of examples of petty corruption considered includes demands for petty bribes by traffic officials followed by police. We examine that it is caused by subjective underweighting of rare events and its objective probabilities. This literature reports results of an experiment, … …American Journal of Applied Sciences, Vol. 2, Issue 13 · 3 Dec 2005 · 8,108 accessesView PDFCite
Research ArticleOpen accessIn the abstractFailure Diagnosis on Discrete Event SystemsSihem Kechida, Nasr Eddine DebbacheThe modern technology advances to a point where it is possible and extensively desirable to improve reliability and the technical process safety. This is achieved by computer implanted FDI procedures (Fault Detection and Isolation). However, the malfunction of actuators, sensors and of the process components, as well as erroneous actions of human operators can have some disastrous consequences in high … …American Journal of Applied Sciences, Vol. 2, Issue 11 · 30 Nov 2005 · 6,889 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of Pulsed Laser Deposition System for the Formation of Web-liked Carbon NanotubesNoorhana Yahya, Beh Hoe Guan, Mansor HashimThis work reports on our earnest effort to develop a pulsed laser ablation deposition system for the production of carbon nanotubes (CNTs). The correct condition such as the pressure, ablation time, power of laser will result in different structures and morphology of the tubes. A T-shaped stainless steel chamber was designed. Nd:YAG laser with 532 nm wavelength, 10.54W output power … …American Journal of Applied Sciences, Vol. 2, Issue 11 · 30 Nov 2005 · 7,037 accessesView PDFCite
Research ArticleOpen accessIn the abstractModeling Load Balancing in Heterogeneous Unstructured P2P SystemsZhi Jun Li, Ming Hong LiaoLoad balancing is a generally concerned problem in peer-to-peer (P2P) systems. Many researches on load balancing in the structured P2P systems have been launched currently, such as Chord or other DHTs. Although the researches on load balancing in unstructured P2P systems are emerged nowadays, the simple mechanisms achieved can only perform effectively in uniform environment. In this study, the influence … …Journal of Computer Science, Vol. 1, Issue 3 · 30 Sep 2005 · 6,785 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimulations of Two-dimensional High Speed Turbulent Compressible Flow in a Diffuser and a Nozzle Blade CascadeK. C. Ng, M. Z. Yusoff, T. F. YusafThis research describes the development of a new structured 2D CFD solver for compressible flow. The high-speed turbulent flow in a diffuser and a cascade of nozzle blade is predicted using standard k-ε turbulence model. The new finite volume CFD solver employs second-order accurate central differencing scheme for spatial discretization and multi-stage Runge-Kutta time integration to solve the set of … …American Journal of Applied Sciences, Vol. 2, Issue 9 · 30 Sep 2005 · 6,552 accessesView PDFCite
