Research ArticleOpen accessIn the abstractWeighting Spatial Information in GIS for Copper Mining ExplorationFarhad Hosseinali, Ali Asghar AlesheikhExploration of new mines is vitally important for human life. Geospatial Information Systems (GIS) can be effectively used in the gathering, weighting, analyzing and presenting spatial and attribute information to facilitate the mine exploration process. The success of mine exploration largely depends on: the identification of governing factors, the determination of their impacts and the selection of suitable models to … …American Journal of Applied Sciences, Vol. 5, Issue 9 · 30 Sep 2008 · 8,609 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimulation of Convective Heat-Transfer Coefficient in a Buried ExchangerTaoufik Mnasri, Rached Ben Younès, Maher Raddaoui, Salem ElouraginiThis study presents analytical models allowing to study a forced convection laminar flow in non-established dynamic and thermic regimes. We treated a flow in a bitubular exchanger in permanent thermal contact with a semi-infinite medium, such as the ground. The wall temperature as well as the wall heat flux evolve in the course of time until a quasi-steady mode. The … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 6,903 accessesView PDFCite
Research ArticleOpen accessIn the abstractThree-Phase Shunt Active Power FilterMoleykutty George, Kartik Prasad BasuActive power filters have been widely used for harmonic elimination. The performance of a conventional three-phase shunt Active Power Filter (APF) using Synchronous Detection Method (SDM) has been compared with Nonlinear Autoregressive-Moving Average (NARMA)-L2 based APF. The novelty of this study lies in the application of NARMA-L2 control to generate the amplitude of the reference supply current required by the … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 7,306 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamic Traffic Light Sequence Algorithm Using RFIDKhalid A.S. Al-Khateeb, Jaiz A.Y. Johari, Wajdi F. Al-KhateebProblem statement: Traffic congestion and tidal flow management were recognized as major problems in modern urban areas, which have caused much frustration and loss of man hours. Approach: In order to solve the problem an intelligent RFID traffic control has been developed. It has circumvented or avoided the problems that usually arise with systems such as those, which use image … …Journal of Computer Science, Vol. 4, Issue 7 · 31 Jul 2008 · 21,778 accessesView PDFCite
Research ArticleOpen accessIn the abstractHydrochemical Differentiation of Salinisation Process of the Water in Endoreic Semi-Arid Basin: Case of Rémila Basin, AlgeriaHouha Belgacem, Kherici Nacer, Kachi Slimane, Valles VincentThe aim of this study is to determine and treat a hierarchical basis of the various mechanisms responsible for the space variation of the water quality in a endoreic semi-arid basin. The water chemistry showed a large variability in space and time. The total dissolved solid (TDS) in water increases from upstream to downstream due to the effect of the … …American Journal of Applied Sciences, Vol. 5, Issue 7 · 31 Jul 2008 · 7,310 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Infrastructure Development on Income Generation: A Study on Jamuna Bridge Project in BangladeshShaikh MoniruzzamanThis research is an attempt to examine the impact of infrastructure development on income generation in the north eastern region of Bangladesh which enjoyed a wide range of amenities after the construction of Jamuna Bridge in 1998. The application of 'difference in difference estimator' using the pooled household level income data of the treatment and control area in the pre … …Journal of Social Sciences, Vol. 4, Issue 2 · 30 Jun 2008 · 8,371 accessesView PDFCite
Research ArticleOpen accessIn the abstractVulnerability Assessment of Power System Using Radial Basis Function Neural Network and a New Feature Extraction MethodAhmed M.A. Haidar, Azah Mohamed, Aini HussainVulnerability assessment in power systems is important so as to determine how vulnerable a power system in case of any unforeseen catastrophic events. This paper presents the application of Radial Basis Function Neural Network (RBFNN) for vulnerability assessment of power system incorporating a new proposed feature extraction method named as the Neural Network Weight Extraction (NNWE) for dimensionality reduction of … …American Journal of Applied Sciences, Vol. 5, Issue 6 · 30 Jun 2008 · 7,155 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Teletaction Control System for Detection of Human Pulse Wave with Applications in TeleoperationsJavad Dargahi, Saeed Sokhanvar, Siamak Najarian, Farhad Tabatabai GhomsheThe design of a smart medical tool that can detect the human pulse and transfer its data to a remote location is presented. The resulting control system can be used to detect the pulse wave of human obtained from the wrist area. Fabrication of the tactile sensor and its calibration procedure are discussed as well. Additionally, the design of the … …American Journal of Applied Sciences, Vol. 5, Issue 6 · 30 Jun 2008 · 6,922 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Tactile Sensor for Detection of Skin Surface Morphology and its Application in Telemedicine SystemsRoozbeh Khodambashi, Siamak Najarian, Ali Tavakoli Golpaygani et al.We proposed a new type of tactile sensor that is capable of determining the surface morphology of skin lesions. The sensor consists of a brass cylinder with an axial bore. Three peripheral bobbins were machined in the cylinder around which three coils have been wound. An iron core can easily move inside the bore. One of the coils acts as … …American Journal of Applied Sciences, Vol. 5, Issue 6 · 30 Jun 2008 · 7,263 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeneralized Shortest Path Problem in Uncertain Environment Based on PSOHayder A. Mukhef, Ekhlas M. Farhan, Mohammed R. JassimGeneralized network problems describe situations in which flow can be generated or consumed through arcs. This research considers generalized shortest path problem in stochastic environment in which the changing rate of flow is random. To satisfy the demands of decision makers, three types of models have been formulated to solve the generalized shortest path problem under different decision criteria. The … …Journal of Computer Science, Vol. 4, Issue 4 · 30 Apr 2008 · 6,756 accessesView PDFCite
