Research ArticleOpen accessEvery word in the titleDetermining the Impact of Darkness on Highway Traffic Shockwave PropagationParameswary Sundara, Othman Che Puan, Mohammad Rosli HaininDuring darkness visibility diminishes resulting in reduced sight distances and drivers are subjected to anxiety that may give way to anger and frustration. However, the study is concerned with traffic shockwave propagation that could be associated with darkness on highways. Based on the hypothesis that darkness may induce temporary traffic shockwave propagation in the presence of substantial traffic volume, darkness … …American Journal of Applied Sciences, Vol. 10, Issue 9 · 24 Aug 2013 · 7,071 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleGeneralization of Dijkstra’s Algorithm for Extraction of Shortest Paths in Directed MultigraphsBashir Alam, Siddhartha Sankar Biswas, M. N. DojaThe classical Dijkstra’s algorithm to find the shortest path in graphs is not applicable to multigraphs. In this study the authors generalize the classical Dijkstra’s algorithm to make it applicable to directed multigraphs. The modified algorithm is called by Generalized Dijkstra’s algorithm or GD Algorithm (GDA in short). The GDA outputs the shortest paths and the corresponding min cost. It … …Journal of Computer Science, Vol. 9, Issue 3 · 29 Apr 2013 · 7,466 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleHybridization of Genetic Algorithm with Parallel Implementation of Simulated Annealing for Job Shop SchedulingThamilselvan Rakkiannan, Balasubramanie PalanisamyProblem statement: The Job Shop Scheduling Problem (JSSP) is observed as one of the most difficult NP-hard, combinatorial problem. The problem consists of determining the most efficient schedule for jobs that are processed on several machines. Approach: In this study Genetic Algorithm (GA) is integrated with the parallel version of Simulated Annealing Algorithm (SA) is applied to the job shop … …American Journal of Applied Sciences, Vol. 9, Issue 10 · 25 Aug 2012 · 7,056 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleShot Detection Using Genetic Edge Histogram and Object Based Video Retrieval Using Multiple FeaturesR. Kanagavalli, K. DuraiswamyAs the usage of multimedia data increasing rapidly, how to get the video data we need efficiently become so important. Recent advances in multimedia technologies allow the capture and storage of video data with relatively inexpensive computers. Problem Statement: However, without appropriate search techniques all these data are hardly usable. Users want to query the content instead of the raw … …Journal of Computer Science, Vol. 8, Issue 8 · 3 Aug 2012 · 6,853 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDynamic Route Shortening and Route Repairing Mechanism for Mobile Ad Hoc NetworksS. Revathi, T. R. RangaswamyProblem statement: Ad hoc Networks are wireless networks without any fixed infrastructure. The network topology changes frequently and unpredictably due to the random movement of the nodes. The Ad Hoc on Demand Distant Vector Routing (AODV) protocol works in a dynamic fashion, by establishing a route on demand and continues that route until it breaks. Due to the changing network … …Journal of Computer Science, Vol. 8, Issue 8 · 11 Jul 2012 · 7,068 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMobile Phone and Short Message Service Appropriation, Usage and Behavioral Issues among University StudentsVimala Balakrishnan, Huck-Soo LooProblem statement: This study aims to explore mobile phone and Short Message Service (SMS) usage among urbanized Malaysian youth. Uses and Gratification theory was used to explore mobile phone purchasing factors, reasons to use mobile phone and SMS, usage pattern and behavioral issues related to mobile phone and SMS. Structured questionnaire surveys and 24 h diaries were distributed to 417 … …Journal of Social Sciences, Vol. 8, Issue 3 · 9 May 2012 · 8,403 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSome Effects of Alternative Foreign Currency Translation Methodologies on two Short-Term Liquidity RatiosPaul E. HoltThis study focused on two short-term liquidity ratios, the current ratio and inventory turnover and attempted to identify, in terms of empirical properties, if and in what ways foreign currency translation methodologies generate different results. Fifty companies’ accounts were translated from U.S. dollars to U.K. pounds. Post-translation Spearman rank correlation coefficients were extremely high for all methodology pairs, but t … …American Journal of Economics and Business Administration, Vol. 3, Issue 4 · 8 Mar 2012 · 7,484 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleIntegration of Genetic Algorithm with Tabu Search for Job Shop Scheduling with Unordered Subsequence Exchange CrossoverR. Thamilselvan, P. BalasubramanieProblem statement: The problem of scheduling n jobs on m machines with each job having specific machine route has been researched over the decade. The Job Shop Scheduling (JSS) is one of the hardest combinatorial optimization problems. Each resource can process at most one job at a time. Approach: This study proposes a new approach to solve a Job Shop … …Journal of Computer Science, Vol. 8, Issue 5 · 24 Feb 2012 · 6,650 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Real Time Practical Approach for Multi Objective Job Shop Scheduling Using Fuzzy Logic ApproachR. Ramkumar, A. Tamilarasi, T. DeviMulti objective Job Shop scheduling is a difficult task in both theoretical and practical solving issues. Problem statement: In the present scenario the modern Engineering and Industrial manufacturing units are facing lot of problems in many aspects such as machining time, raw material movement, man power requirement, electricity demand and customer satisfaction. Approach: A triangular fuzzy membership function is used … …Journal of Computer Science, Vol. 8, Issue 4 · 14 Feb 2012 · 6,258 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Effect of Thyristor Controlled Series Capacitor on Transient Stability of Single Machine Infinite Bus System with the Exact Short Transmission Line ModelPrechanon KumkratugProblem statement: It is becoming increasingly important to fully utilize the existing transmission system assets due to environmental legislation, rights-of-way issues, costs of construction and deregulation policies that were introduced in recent years. The Thyristor Controlled Series Capacitor (TCSC) has been proposed for better control power flow and dynamic performance. The exact short transmission line model consists of the resistance … …American Journal of Applied Sciences, Vol. 9, Issue 3 · 2 Feb 2012 · 7,466 accessesView PDFCite
