Research ArticleOpen accessEvery word in the titleSmart Card Identification Management Over A Distributed Database ModelOlatubosun OlabodeProblem statement: An effective national identification system is a necessity in any national government for the proper implementation and execution of its governmental policies and duties. Approach: Such data can be held in a database relation in a distributed database environment. Till date, The Nigerian government is yet to have an effective and efficient National Identification Management System despite the … …Journal of Computer Science, Vol. 7, Issue 12 · 15 Oct 2011 · 6,864 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMoments of Order Statistics from Nonidentically Distributed Three Parameters Beta typeI and Erlang Truncated Exponential VariablesA. A. Jamjoom, Z. A. AL-SaiaryProblem statement: Moments of order statistics of independent non-identically distributed (INID) random variables is not an easy subject to deal with for continuous distributions. One is forced to use messy algebraic calculations (whether one uses permanents or not). This was the motivation behind this study. In this study the moments of order statistics arising from independent nonidentically distributed three parameters … …Journal of Mathematics and Statistics, Vol. 6, Issue 4 · 31 Dec 2010 · 7,373 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleProgrammable System on Chip Distributed Communication and Control Approach for Human Adaptive Mechanical SystemAhmad ‘Athif Mohd Faudzi, Koichi SuzumoriProblem statement: Communication and control are two main components in any Mechatronics system. They can be designed either by centralized or decentralized approach. Both approaches can be chosen based on application designed and specific requirements of the designer. In this study, decentralized or normally called distributed approach was selected to solved communication and control of a human adaptive mechanical system … …Journal of Computer Science, Vol. 6, Issue 8 · 31 Aug 2010 · 6,733 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleData Replication Using Read-One-Write-All Monitoring Synchronization Transaction System in Distributed EnvironmentNoraziah Ahmad, Ahmed N. Abdalla, Roslina Mohd SidekNowadays, the demand of transmitted information over networks increase rapidly and the demand for steady bandwidth seems to be out of control. Particularly organizations need to provide updated data to users that might be geographically remote and handling a vast amount of requested data distributed in multiple sites. Problem statement: Replication in distributed environment has become increasingly popular due to … …Journal of Computer Science, Vol. 6, Issue 10 · 30 Jul 2010 · 7,048 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleLoad Balancing of Distributed Systems Based on Multiple Ant Colonies OptimizationAl-Dahoud Ali, Mohamed A. Belal, Moh’d Belal Al-ZoubiProblem statement: Ant Colony Optimization (ACO) provides a meta-heuristic optimization tool and collective intelligence model to several applications such as routing and load balancing. A lot of work found in the literature on using ACO in load balancing. However, as far as our knowledge, there was no work relating load balancing in distributed systems with ACO. Approach: In this study, … …American Journal of Applied Sciences, Vol. 7, Issue 3 · 31 Mar 2010 · 7,209 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAn Optimal Control Approach to Inventory-Production Systems with Weibull Distributed DeteriorationMd. Azizul Baten, Anton Abdulbasah KamilProblem statement: We studied the inventory-production system with two-parameter Weibull distributed deterioration items. Approach: The inventory model was developed as linear optimal control problem and by the Pontryagin maximum principle, the optimal control problem was solved analytically to obtain the optimal solution of the problem. Results: It was then illustrated with the help of an example. By the principle of … …Journal of Mathematics and Statistics, Vol. 5, Issue 3 · 30 Sep 2009 · 7,549 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDistributed Mutual Exclusion Based on Causal OrderingMohamed Naimi, Ousmane ThiareProblem statement: Causality among events, more formally the causal ordering relation, is a powerful tool for analyzing and drawing inferences about distributed systems. The knowledge of the causal ordering relation between processes helps designers and the system itself solve a variety of problems in distributed systems. In distributed algorithms design, such knowledge helped ensure fairness and liveness in distributed algorithms, … …Journal of Computer Science, Vol. 5, Issue 5 · 30 May 2009 · 6,748 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleUtilization of Distributed Architecture Based on Internet GIS for Geomorphologic Data and Environmental Management: Case Study of Damavand Volcano Conic, IranEbrahim Moghimi, Ali Mansourian, Mojgan Zarei Nejad, Mohammad Saber MoghimiDespite the great significance of geomorphologic-environmental data in different disciplines, there are sundry problems in relation to availability, accessibility and their applicability. Primarily the problems dealing with these data were investigated and then technical solutions to remove each of the above problems and how to manage geomorphologic-environmental data were suggested. The solution for availability lies in participation of various organizations … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 7,046 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Dynamic Resource Synchronizer Mutual Exclusion Algorithm for Wired/Wireless Distributed SystemsAhmed Sharieh, Mariam Itriq, Wafa DbabatA mobile host has small memory, relatively slow processor, low power batteries, and communicate over low bandwidth wireless communication links. Existing mutual exclusion algorithms for distributed systems are not enough for mobile systems because of several limitations. In this study, a mutual exclusion algorithm that is more suitable for mobile computer systems is developed. The algorithm tends to minimize the … …American Journal of Applied Sciences, Vol. 5, Issue 7 · 31 Jul 2008 · 7,161 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Novel Distributed Clustering Algorithm for Mobile Ad-hoc NetworksSahar Adabi, Sam Jabbehdari, Amirmasoud Rahmani, Sepideh AdabiThis paper proposed a new Distributed Score Based Clustering Algorithm (DSBCA) for Mobile Ad-hoc Networks (MANETs).In MANETs, select suitable nodes in clusters as cluster heads are so important. The proposed Clustering Algorithm considers the Battery Remaining, Number of Neighbors, Number of Members, and Stability in order to calculate the node's score with a linear algorithm. After each node calculates its … …Journal of Computer Science, Vol. 4, Issue 2 · 28 Feb 2008 · 7,114 accessesView PDFCite
