Research ArticleOpen accessIn the abstractWeighted Centroid Modified Simplex and Linear Constrained Response Surface Optimization Methods for the Xbar-R Chart Variable DeterminationPongchanun LuangpaiboonProblem statement: Although economic Xbar-R chart designs do guarantee the minimal operating cost, they typically have poor levels of statistical performance measures. The obvious limitation of the economic design is that the Type I error rate seems to be very high for many situations and will cause a large number of false alarms. This situation leads to an investigation of … …Journal of Computer Science, Vol. 7, Issue 6 · 14 Jun 2011 · 7,115 accessesView PDFCite
Research ArticleOpen accessIn the abstractObject Exploration Using a Three-Axis Tactile Sensing InformationS. C. Abdullah, Jiro Wada, Masahiro Ohka, Hanafiah YussofProblem statement: To advance the robust object recognition of robots, we present an algorithm for object exploration based on three-axis tactile data that is necessary and sufficient for the evaluation of contact phenomena. Approach: The object surface contour is acquired by controlling the finger position so that the normal force, measured by optical three-axis tactile sensors, remains constant as two … …Journal of Computer Science, Vol. 7, Issue 4 · 4 Apr 2011 · 7,313 accessesView PDFCite
Research ArticleOpen accessIn the abstractModeling and Analysis of MRR, EWR and Surface Roughness in EDM Milling through Response Surface MethodologyA.K.M. Asif Iqbal, Ahsan Ali KhanProblem statement: Electrical Discharge Machining (EDM) has grown over the last few decades from a novelty to a mainstream manufacturing process. Though, EDM process is very demanding but the mechanism of the process is complex and far from completely understood. It is difficult to establish a model that can accurately predict the performance by correlating the process parameters. The optimum … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 4 Nov 2010 · 9,606 accessesView PDFCite
Research ArticleOpen accessIn the abstractProgrammable System on Chip Distributed Communication and Control Approach for Human Adaptive Mechanical SystemAhmad ‘Athif Mohd Faudzi, Koichi SuzumoriProblem statement: Communication and control are two main components in any Mechatronics system. They can be designed either by centralized or decentralized approach. Both approaches can be chosen based on application designed and specific requirements of the designer. In this study, decentralized or normally called distributed approach was selected to solved communication and control of a human adaptive mechanical system … …Journal of Computer Science, Vol. 6, Issue 8 · 31 Aug 2010 · 6,733 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Process Parameters on Electrical Discharge Machined Job Surface IntegrityA.K.M. Asif Iqbal, Ahsan Ali KhanProblem statement: Electrical Discharge Machining (EDM) is the most widely used non conventional machining process for removing material from workpiece by means of a series of repeated electric discharges. Electrical Discharge milling (ED-milling) is an emerging technology where a cylindrical tool electrode follows a programmed path in order to obtain the desired shape of a part. During machining of metals … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 8,584 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimization of Cutting Parameters Based on Surface Roughness and Assistance of Workpiece Surface Temperature in Turning ProcessAdeel H. Suhail, N. Ismail, S. V. Wong, N. A. Abdul JalilProblem statement: In machining operation, the quality of surface finish is an important requirement for many turned workpieces. Thus, the choice of optimized cutting parameters is very important for controlling the required surface quality. Approach: The focus of present experimental study is to optimize the cutting parameters using two performance measures, workpiece surface temperature and surface roughness. Optimal cutting parameters … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 12,941 accessesView PDFCite
Research ArticleOpen accessIn the abstractPiecewise Sliding Mode Decoupling Fault Tolerant Control SystemRafi Youssef, Hui PengProblem statement: Proposed method in the present study could deal with fault tolerant control system by using the so called decentralized control theory with decoupling fashion sliding mode control, dealing with subsystems instead of whole system and to the knowledge of the author there is no known computational algorithm for decentralized case, Approach: In this study we present a decoupling … …American Journal of Applied Sciences, Vol. 7, Issue 1 · 31 Jan 2010 · 7,388 accessesView PDFCite
Research ArticleOpen accessIn the abstractRobust Position Controller for a Permanent Magnet Synchronous ActuatorChams-Eddine Feraga, Abdelkrim Moussaoui, Abdallah Bouldjedri, Ali YousfiProblem statement: The present study investigated with the application of a robust control scheme to improve the performance of a simplified indirect field oriented for small power surface mounted Permanent Magnet (PM) synchronous actuators. Approach: The suggested model was implemented using a simplified state feedback with no need to measure the current values to compute the control algorithm. Results: The … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,673 accessesView PDFCite
Research ArticleOpen accessIn the abstractDoes Trichomes on the Plant Epidermic Surface Disturb Ants Locomotion?Danon Clemes Cardoso, Maykon Passos Cristiano, Lenise Cristina Moraes Vilela, Tiago de Arruda MartinsProblem Statement: Many morphological characteristics, both physical and chemical, are used in the defense against herbivores on plants. Trichomes are structures used by plants as physics defense and when associated with glands combine physics and chemistry defense. Many species of ants are herbivores and use leaves and seeds, others ants use Extra Floral Nectars as a food resource, and the … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 1 · 31 Mar 2009 · 9,350 accessesView PDFCite
Research ArticleOpen accessIn the abstractNumerical Investigation of Flow Control by Suction and Injection on a Subsonic AirfoilM. H. Shojaefard, A. R. Noorpoor, A. Avanesians, M. GhaffarpourThis study presents a numerical study concerning flow control by suction and injection. The case studied is the flow field over a subsonic airfoil with four suction and injection slots on the suction side of the airfoil. Five different angles of attack, 0, 5, 10, 13.3 and 20 with the Mach number of 0.15 are studied. Three cases are studied … …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 7,428 accessesView PDFCite
