Research ArticleOpen accessIn the abstractThe Influence of pH on Nonlinear Refractive Index of Bromophenol BlueF.Z. Henari, K.G. CulliganProblem statement: Bromophenol blue is a pH indicator, a kind of chemical that changes colour when pH goes up or down over a narrow linear dynamic range of 3.0-4.6 pH units. Therefore a good approach must be taken to extend the linear response of the indicator in order to have simple calibration and precise measurements of PH sensors. The purpose … …Physics International, Vol. 1, Issue 1 · 31 Mar 2010 · 15,956 accessesView PDFCite
Research ArticleOpen accessIn the abstractHyperspectral Remote Sensing for Tropical Rain ForestKamaruzaman Jusoff, Kasawani IbrahimProblem statement: Sensing, mapping and monitoring the rain forest in forested regions of the world, particularly the tropics, has attracted a great deal of attention in recent years as deforestation and forest degradation account for up to 30% of anthropogenic carbon emissions and are now included in climate change negotiations. Approach: We reviewed the potential for air and spaceborne hyperspectral … …American Journal of Applied Sciences, Vol. 6, Issue 12 · 31 Dec 2009 · 8,581 accessesView PDFCite

Kamel, Rosli BesarData glove is a new dimension in the field of virtual reality environments, initially designed to satisfy the stringent requirements of modern motion capture and animation professionals. In this study we try to shift the implementation of data glove from motion animation towards signature verification problem, making use of the offered multiple degrees of freedom for each finger and for … …American Journal of Applied Sciences, Vol. 6, Issue 2 · 28 Feb 2009 · 7,152 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntelligent OkiKoSenPBX1 Security Patrol Robot via Network and Map-Based Route PlanningMbaïtiga ZacharieProblem statement: With an increased demand for security and limited numbers of trained security personnel, some security mangers have a lot of ground to police and limited staff to cover it. To compensate for shortages of security staff and to reduce the stress of security managers, we have developed an intelligent patrol robot system called "OkiKoSenPBX1". The system integrates a … …Journal of Computer Science, Vol. 5, Issue 1 · 31 Jan 2009 · 7,418 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of Suspended Sediments Concentration in Surface Waters, Using Modis ImagesMobasheri Mohammad RezaRemote sensing from air-borne and space-borne sensors have proved to be a useful method for Suspended Sediment Concentration (SSC) estimation as it provides an instantaneous and synoptic view of suspended sediments that would otherwise be unavailable. The reason for the success of remote sensing in such surveys is the strong positive relationship that exists between SSC and remotely sensed water … …American Journal of Applied Sciences, Vol. 5, Issue 7 · 31 Jul 2008 · 7,011 accessesView PDFCite
Research ArticleOpen accessIn the abstractTime-Marching Method for Computations of High-Speed Compressible Flow on Structured and Unstructured GridK.C. Ng, M.Z. Yusoff, K. Munisamy et al.The development of Computational Fluid Dynamics (CFD) compressible codes for 2D structured quadrilateral grid and 3D unstructured hexahedral grid is described. The high-speed flow in a nozzle blade cascade is predicted numerically by solving the 2D/3D Euler Equations in a coupled manner. The new finite volume CFD solvers employ second-order accurate central differencing scheme for spatial discretization and multi-stage Runge-Kutta … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 2 · 30 Jun 2008 · 7,354 accessesView PDFCite
