Research ArticleOpen accessIn the abstractExperimental Investigation Of Polymeric Compound Cross Section SpringsMayas Al-Mahasne, Tareq A. Abu ShreehahThis paper presents an experimental investigation of the characteristic of the compound cross section springs on models made from polymeric materials (organic glass). Two constructive variants of the compound spring sections were specified with the help of criteria of similarity. The criterion of similarity of natural and model springs was determined by the simulation method at particular spring deflection. The … …American Journal of Applied Sciences, Vol. 4, Issue 1 · 30 Apr 2007 · 6,758 accessesView PDFCite
Research ArticleOpen accessIn the abstractDiamond Pressing on the Wear Resistance and the State of Heat Treated Alloy Steel SurfacesUbeidulla Al-QawabehaIn manufacturing processes, surfaces and their properties are as important as the bulk properties of the materials. Surface treatment is an important aspect of all manufacturing processes. It has been used to impart certain physical and mechanical properties, such as appearance, corrosion, friction, wear and fatigue resistance. Widely used methods of finishing treatment that create necessary parts with the given … …American Journal of Applied Sciences, Vol. 4, Issue 3 · 31 Mar 2007 · 7,105 accessesView PDFCite

Research ArticleOpen accessIn the abstractDesign and Implementation of an Adaptive Control for a RobotIraj Hassanzadeh, Abbas Harifi, Farid ArvaniThis research investigates the performance of an adaptive controller for five-bar linkage robot. The proposed controller was entirely independent on the physical specifications of the robot. The controller was examined as the dynamics of the mechanical system varies for various environment conditions, which make it an ambiguous system. In this study, the introduced controller was designed based on the governing … …American Journal of Applied Sciences, Vol. 4, Issue 2 · 28 Feb 2007 · 6,647 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of a Prototype Automated Sorting System for Plastic RecyclingD. A. Wahab, A. Hussain, E. Scavino et al.Automated sorting for plastic recyclables has been seen as the way forward in the plastic recycling industry. Automated sorting provides significant improvements in terms of efficiency and consistency in the sorting process. In the case of macro sorting, which is the most common type of automated sorting, efficiency is determined by the mechanical details of the material handling system as … …American Journal of Applied Sciences, Vol. 3, Issue 7 · 31 Jul 2006 · 8,829 accessesView PDFCite
Research ArticleOpen accessIn the abstractNanocrystalline Powders of Alkaline-Earth Phosphates as Precursors for BioceramicsParhi Purnendu, A. Ramanan, Alok R. RayBone is a nanocomposite made of calcium phosphates and collagen. Collagen has a typical fibrous structure, with diameter ranging from 100 nm to 2 μm. It is suggested that calcium hydroxyapatite, Ca10(PO4)6(OH)2 in the size range 5-50 nm embedded in the collagen framework provides mechanical strength to bone. Among calcium phosphates, apatites are found to be the most suitable for … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 2 · 30 Jun 2006 · 6,546 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesigning Omni-Directional Mobile Robot with Mecanum WheelJefri Efendi Mohd Salih, Mohamed Rizon, Sazali Yaacob et al.This study presents the processes undertaken in the design and development of an intelligent omni-directional mobile robot using four custom-made mecanum wheels. The mecanum wheel developed consists of nine rollers made from delrin. All mecanum wheels are independently powered using four units of precisian gear DC motors and the wheel/motor assemblies were mounted directly to the robot chassis made using … …American Journal of Applied Sciences, Vol. 3, Issue 5 · 31 May 2006 · 9,601 accessesView PDFCite
Research ArticleOpen accessIn the abstractPreparation of Magnetic Paper from Kenaf: Lumen Loading and in situ Synthesis MethodC. H. Chia, S. Zakaria, S. Ahamd et al.Magnetic papers have been successfully prepared from unbleached kenaf (hibiscus cannabinus) kraft pulps via the lumen loading and in situ synthesis process. The lumen loading method allows the magnetic fillers to be introduced into the lumen of fibres and at the same time leaving the external surfaces free from filler, resulting the better inter-fibre bonding and subsequently its papermaking properties … …American Journal of Applied Sciences, Vol. 3, Issue 3 · 31 Mar 2006 · 7,516 accessesView PDFCite
Research ArticleOpen accessIn the abstractAutomated 3D Particle Field Extraction and Tracking System Using Digital in-line HolographyHesham EldeebDigital holography for 3D particle field extraction and tracking is an active research topic. It has a great application in realizing characterization of micro-scale structures in microelectromechanical systems (MEMS) with high resolution and accuracy. In-line configuration is studied in this study as the fundamental structure of a digital holography system. Digital holographic approach, not only eliminates wet chemical processing and … …Journal of Computer Science, Vol. 2, Issue 2 · 28 Feb 2006 · 6,539 accessesView PDFCite
