Research ArticleOpen accessIn the abstractDevelopment of a Prototype Automated Sorting System for Plastic RecyclingD. A. Wahab, A. Hussain, E. Scavino et al.Automated sorting for plastic recyclables has been seen as the way forward in the plastic recycling industry. Automated sorting provides significant improvements in terms of efficiency and consistency in the sorting process. In the case of macro sorting, which is the most common type of automated sorting, efficiency is determined by the mechanical details of the material handling system as … …American Journal of Applied Sciences, Vol. 3, Issue 7 · 31 Jul 2006 · 8,824 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimal Rejuvenation Scheduling of Distributed Computation Based on Dynamic ProgrammingHiroyuki Okamura, Kazuki Iwamoto, Tadashi DohiRecently, a complementary approach to handle transient software failures, called software rejuvenation, is becoming popular as a proactive fault management technique in operational software systems. In this study, we develop the optimal scheduling algorithms to trigger software rejuvenation in distributed computation circumstance. In particular, we focus on two different computation circumstances in terms of detection of failures. Based on the … …Journal of Computer Science, Vol. 2, Issue 6 · 30 Jun 2006 · 6,385 accessesView PDFCite
Research ArticleOpen accessIn the abstractNa,K-ATPase α Subunit-like Immunoreactive Proteins in Human Body FluidsJeng-Hsiung F. PengNa,K-ATPase was recently considered a target for breast cancer treatment since its potent inhibitors ouabain and related digitalis compounds that were reported circulating in body fluids before, were found to possess potent anti-breast cancer activity. Based on this finding, it is hypothesized that Na,K-ATPase derivatives could be circulating in the body and potential candidate biomarkers for early disease detection. Western … …American Journal of Immunology, Vol. 2, Issue 1 · 31 Mar 2006 · 6,892 accessesView PDFCite

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 · 6,918 accessesView PDFCite
Research ArticleOpen accessIn the abstractFault Reconstruction Using Sliding Mode ObserversK. Hakiki, B. Mazari, A. Liazid, S. DjaberIn this study, a nonlinear sliding observer is proposed to explicitly reconstruct fault signals. The novelty lies in the application of the equivalent output injection concept. Previous work in the area of fault detection has used disruption of the sliding motion to detect faults. The aim of the present study was to design a robust observer that slides in the … …American Journal of Applied Sciences, Vol. 3, Issue 1 · 31 Jan 2006 · 6,680 accessesView PDFCite
Research ArticleOpen accessIn the abstractReal-time Optimistic Concurrency Control based on Transaction Finish DegreeHan Qilong, Hao ZhongxiaoConcurrency control is one of the main issues in the studies of real-time database systems. Optimistic concurrency control algorithms have the attractive properties of being non-blocking and deadlock-free. However, they have the problems of late conflict detection and transaction restarts. Although the number of transaction restarts is reduced by dynamic adjustment of serialization order in real-time database systems, they are … …Journal of Computer Science, Vol. 1, Issue 4 · 31 Dec 2005 · 6,688 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Advance Approach to Evaluate the Performance of the TCP NetworksIbrahiem M.M. El Emary, Farouq Al TaweelIn this study, we present a new approach for estimating the performance of the TCP network depending on a mathematical formula which converts the conceptual performance parameter to a valuable one. With respect to TCP network performance, we consider the Random Early Detection (RED) and RED-Based algorithms where both RED and RED-Based follow the Active Queue Management (AQM) approach in … …American Journal of Applied Sciences, Vol. 2, Issue 9 · 30 Sep 2005 · 6,522 accessesView PDFCite
Research ArticleOpen accessIn the abstractInduction of Micronuclei in Mice Lymphocytes Exposed to Microwave and TolueneS. B. Mortazavi, A. Safari, A. Khavanin et al.Increasing applications of microwave radiation are of great concern with regard to public health. Several studies have been conducted detect effects of microwave exposure genetic material leading to negative or questionable results. The Micronucleus (MN) assay which is proved to be a useful method for detection of radiation exposure-induced cytogenetic damage was used in the present study to investigate the … …American Journal of Applied Sciences, Vol. 2, Issue 9 · 30 Sep 2005 · 6,614 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn Analysis and Design of the Enhanced Firewall for Intranet SecurityU. K. Singh, A. K. Ramani, N. S. ChaudhariIntranet often employ an Internet firewall to mitigate risks of system penetration, data theft, data destruction and other security breaches. Conventional Internet firewalls impose an overly simple inside vs. outside model of security that is incompatible with many business practices that require extending limited trust to external entities. Additionally, firewall security perimeters are somewhat weak: they provide no protection from … …Journal of Computer Science, Vol. 1, Issue 2 · 30 Jun 2005 · 6,709 accessesView PDFCite
Research ArticleOpen accessIn the abstractGender Differences in Baseline Levels of Vascular Endothelial Growth Factor in the Plasma of Alaskan Sled DogsScott W. Kemp, Arleigh J. Reynolds, Lawrence K. DuffyAngiogenesis and vasculogenesis are two very important processes in the development and maintenance of mammalian health. In sled dogs, the angiogenic role is to supply and support tissue with ample vasculature, thus providing a route of access for the transportation of essential nutrients, including oxygen and the removal of waste in a sustained fashion.
