Research ArticleOpen accessIn the abstractScheduling of Automated Guided Vehicle and Flexible Jobshop using Jumping Genes Genetic AlgorithmP. Paul Pandian, S. Saravana Sankar, S. G. Ponnambalam, M. Victor RajProblem statement: Now a day’s many researchers try Genetic algorithm based optimization to find near optimal solution for flexible job shop. It is a global search. In Our study in the GA, some changes are made to search locally and globally by adding jumping genes operation. A typical flexible job shop model is considered for this research study. For that … …American Journal of Applied Sciences, Vol. 9, Issue 10 · 25 Aug 2012 · 7,306 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Hydrogen Addition on Diesel Engine Operation and NOx Emission: A Thermodynamic StudyPrateep Chaisermtawan, Sathaporn Chuepeng, Sompop JarungthammachoteProblem statement: The worldwide increasing energy demand and the environmental problem due to greenhouse gas emission, especially produced from fossil fuel combustion, have promoted research work to solve these crises. Diesel engine has proven to be one of the most effective energy conversion systems. It is widely used for power generation, land vehicles and marine power plant. To reduce diesel … …American Journal of Applied Sciences, Vol. 9, Issue 9 · 4 Aug 2012 · 7,767 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntegration 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 accessIn the abstractSecurity Challenges in Multicast Communication for Mobile Ad Hoc NetworkS. Gunasekaran, K. DuraiswamyProblem statement: Multicasting communication network accepted a single message from an application and delivered copies of the message to multiple recipients at different locations. Recently, there has been an explosion of research literature on multicast communication environment. The objective of this study were to contribute the complexity of supporting current multicast applications, (i) the lack of reliable multicast transport mechanisms … …Journal of Computer Science, Vol. 6, Issue 5 · 31 May 2010 · 6,125 accessesView PDFCite
Research ArticleOpen accessIn the abstractReducing the Environmental Impact of Olive Mill WastewaterAwni Khatib, Fathi Aqra, Nader Yaghi et al.Problem Statement: A research was needed to monitor the environmental impact of olive mill wastewater (OMW): production and relative production of olive mill waste. This was achieved by collecting data from 92 local olive mills in order to study the olive production yield, water consumption in olive washing and in oil recovery, wastewater generation relative to olive processed and oil … …American Journal of Environmental Sciences, Vol. 5, Issue 1 · 28 Feb 2009 · 8,043 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimulink Model of Direct Torque Control of Induction MachineH.F. Abdul Wahab, H. SanusiDirect torque control (DTC) is one of the most excellent control strategies of torque control in induction machine. It is considered as an alternative to the field oriented control (FOC) or vector control technique. These two control strategies are different on the operation principle but their objectives are the same. They aim to control effectively the torque and flux. Torque … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 8,865 accessesView PDFCite
Research ArticleOpen accessIn the abstractFrom Flexicurity to FlexicArity? Gendered Perspectives on the Danish modelLise Lotte HansenIn Europe, flexicurity is seen as a way to develop labour markets so they will stay or be more competitive and at the same time secure the European welfare tradition. The Danish welfare society builds on a division of work and co-operation between the labour market and the welfare state. This division and co-operation also applies to the Danish flexicurity … …Journal of Social Sciences, Vol. 3, Issue 2 · 30 Jun 2007 · 8,007 accessesView PDFCite
Research ArticleOpen accessIn the abstractHuman-Robot Interface over the Web Based Intelligent SystemDesa Hazry, Masanori Sugisaka, Taki YujiThis research extends the capability for the new technology platform by Remote Data Inspection System (RDIS) server from Furukawa Co., Ltd. enabling the integration of standard Hypertext Markup Language (HTML) programming and RDIS tag programming to create a user-friendly “point-and-click” web-based control mechanism. The integration allows the users to send commands to mobile robot over the Internet. Web-based control enables … …American Journal of Applied Sciences, Vol. 3, Issue 1 · 31 Aug 2006 · 6,955 accessesView PDFCite
Research ArticleOpen accessIn the abstractSingle-Electron Transistor (SET) Process and Device Simulation Using SYSNOPSYS TCAD ToolsUda Hashim, Amiza RasmiSimulation of semiconductor device fabrication and operation is important to the design and manufacture of integrated circuits because it provides insights into complex phenomena that cannot obtained through experimentation or simple analytic models. Process and device simulation is commonly using for the design of new very large scale integration (VLSI) devices and processes. Simulation programs serves as exploratory tools in … …American Journal of Applied Sciences, Vol. 3, Issue 7 · 31 Jul 2006 · 7,418 accessesView PDFCite
Research ArticleOpen accessIn the abstractMeasurement of Cooling Load-Based Occupant Behavior in Under-Actuated Zones: A Time-Variance ApproachYaddarabullah, Yusuf Maulana Akbar, Aedah Binti Abd Rahman, Amna SaadThis research is dedicated to the enhancement of Heating, Ventilation, and Air-Conditioning (HVAC) systems through an innovative investigation of occupant behavior within under-actuated zones. These zones are strategically positioned to elevate indoor air quality and comfort through the intelligent utilization of HVAC systems. However, accurately measuring the cooling loads within these zones, which are inherently influenced by the presence of … …American Journal of Applied Sciences, Vol. 20, Issue 1 · 11 Dec 2023 · 6,158 accessesView PDFCite
