Research ArticleOpen accessIn the abstractA Particle Swarm Optimization Based Edge Preserving Impulse Noise FilterS. Mohamed Mansoor Roomi, P.L. Muthu Karuppi, P. Rajesh, B. Guru RevathiProblem statement: Image sensors and communication channels often introduce impulse noise in image transmission. The most common filters available to remove such noise are median filter and its variants but the major drawbacks identified with them are blurring of edge detail and low noise suppression. To preserve the sharp and useful information in the image, the filtering algorithms are required … …Journal of Computer Science, Vol. 6, Issue 9 · 30 Sep 2010 · 7,477 accessesView PDFCite
Research ArticleOpen accessIn the abstractSensorization of Robotic Hand Using Optical Three-Axis Tactile Sensor: Evaluation with Grasping and Twisting MotionsHanafiah Yussof, Jiro Wada, Masahiro OhkaProblem statement: Sensitization of robot hand is still remaining as crucial issue since most of robot hand systems nowadays are only capable to grasp a predefined specific object. It is still difficult for robot hand system to realize human-like tactile sensation. Some common problems in robot hand system are low accuracy sensing device, sensors are not robust enough for long … …Journal of Computer Science, Vol. 6, Issue 8 · 31 Aug 2010 · 7,851 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign of a Distributed Control System Using a Personal Computer and Micro Control Units for Humanoid RobotsMitsuhiro Yamano, Akihiro Ochiai, Yuichi Suzukawa et al.Problem statement: Humanoid robots have many motors and sensors and many control methods are used to carry out complicated tasks of the robots. Therefore, efficient control systems are required for the robots. Approach: This study presented a distributed control system using a Personal Computer (PC) and Micro Control Units (MCUs) for humanoid robots. Distributed control systems have the advantages that … …Journal of Computer Science, Vol. 6, Issue 8 · 31 Aug 2010 · 7,531 accessesView PDFCite
Research ArticleOpen accessIn the abstractEdge Tracing Manipulation of Clothes Based on Different Gripper TypesKhairul Salleh Mohamed Sahari, Hiroaki Seki, Yoshitsugu Kamiya, Masatoshi HikizuProblem statement: Edge tracing is considered important for deformable object manipulation in order to spread and reveal the original shape of an object before it can be sorted. It is important in unfolding clothes to reveal its original state during sorting. Tracing in this study context involved tracing the clothes edge, with the robot arm movement based on feedback from … …Journal of Computer Science, Vol. 6, Issue 8 · 31 Aug 2010 · 8,030 accessesView PDFCite
Research ArticleOpen accessIn the abstractEco-Friendly Synthesis of Fucoidan-Stabilized Gold NanoparticlesKriengsak Lirdprapamongkol, Warangkana Warisnoicharoen, Suwicha Soisuwan, Jisnuson SvastiProblem statement: Metallic gold nanoparticles (AuNPs) are widely used in many applications including medical, pharmaceutical, diagnostics and sensors. The chemical synthesis of AuNPs normally requires synthetic materials which might cause the toxicological concerns. The use of naturally occurring materials like fucoidans for successful synthesis of AuNPs is of interests. Approach: Fucoidans as sulfated polysaccharides from marine algae Cladosiphon okamuranus (o-fucoidan) … …American Journal of Applied Sciences, Vol. 7, Issue 8 · 31 Aug 2010 · 9,630 accessesView PDFCite
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
