Research ArticleOpen accessIn the abstractA Drives and Control Integrated Time-Domain Dynamic Analysis and Modeling Approach Applied To Ultra-Precision Machine ToolsTianjian Li, Shijin Chen, Haijun Zhang, Kai ChengProblem statement: Machines dynamic performance depends not only upon the mechanical structure and components but also the drives and control system. However, the design of the machines is still at the nascent stage by working on an individual machine basis, hence lacks generic scientific approach and design guideline. Approach: Using computer models integrated drives and control system to predict the … …Current Research in Nanotechnology, Vol. 2, Issue 1 · 29 Jul 2011 · 8,094 accessesView PDFCite
Research ArticleOpen accessIn the abstractBioengineering Assessment on Sloppy GroundMu'azu Mohammed Abdullahi, Nazri Bn Ali, Kamarudin Bn Haj AhmedProblem statement: Soft engineering solution of sloppy surface utilizes mechanical and hydrological effects of vegetation. The hydrological effects driven by transpiration, induces an increase in matric suction and consequently tension also increase along with the decrease of moisture. Therefore once the horizontal stress of the soil exceeds the limit of tensile strain of the soil cracks occurs. Approach: The negative … …American Journal of Environmental Sciences, Vol. 6, Issue 4 · 31 Aug 2010 · 7,246 accessesView PDFCite
Research ArticleOpen accessIn the abstractWireless Communication with a Microprocessor Based Ultrasonic Meter for Flow MeasurementsMahmoud Z. IskandaraniProblem statement: Although the traditional metering system and method for controlling flow is generally safe, reliable and robust, it does suffer certain drawbacks, such as limited accuracy and the ability to implement complex reactive rate designs. Hence, there is a need for a circuit and method of increasing metering accuracy, as well as the position control accuracy for variable flow … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 7,590 accessesView PDFCite
Research ArticleOpen accessIn the abstractNumerical Analysis of Pressure Pulses in the Jerk Fuel Injection SystemsR. A. Baker, T. FirozComputer software has been developed and described in the present study of thorough parametric analysis and design of a mechanical diesel fuel injection system. The method is based on the numerical solution of one dimensional, unsteady, incompressible flow equations through the fuel pipe along with appropriate initial condition, pump end boundary condition and nozzle end boundary condition. Method of characteristics … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 7,161 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Characteristic of two Cultivars of Winter Common Wheat (Triticum Aestivum L.) Cultivated in the Southeast of Kazakhstan using the Drip Irrigation TechnologyZhanar Muratovna Yeraliyeva, Meruyert Sakenovna Kurmanbayeva, Karina Khamidovna Makhmudova et al.The purpose of our research was studying the indicators of grain quality, productivity and analysis of anatomical stem structure during the full maturity of two cultivars of winter common wheat. Novelty of work consists in carrying out such a research using a local standard cultivar Almaly and a new cultivar SWW 2/127 grown using the drip irrigation technology. Researches were … …OnLine Journal of Biological Sciences, Vol. 17, Issue 2 · 30 May 2017 · 7,269 accessesView PDFCite
Research ArticleOpen accessIn the abstractHybrid Ceramo-Polymeric Nanocomposite for Biomimetic Scaffolds Design and PreparationRaffaella Aversa, Relly Victoria V. Petrescu, Roberto Sorrentino et al.Biomimetics, biomechanics and tissue engineering are three multidisciplinary fields that have been contemplated in this research to attain the objective of improving prosthetic implants reliability. Since testing and mathematical methods are closely interlaced, a promising approach seemed to be the combination of in vitro and in vivo experiments with computer simulations (in silico). An innovative biomimetics and biomechanics approach and … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 30 Nov 2016 · 8,276 accessesView PDFCite
Research ArticleOpen accessIn the abstractESTIMATIONS OF TOTAL MASS AND ENERGY OF THE OBSERVABLE UNIVERSEDimitar ValevThe recent astronomical observations indicate that the expanding universe is homogeneous, isotropic and asymptotically flat. The Euclidean geometry of the universe enables to determine the total gravitational and kinetic energy of the universe by Newtonian gravity in a flat space. By means of dimensional analysis, we have found the mass of the observable universe close to the Hoyle-Carvalho formula M∼c3/(GH). … …Physics International, Vol. 5, Issue 1 · 21 Mar 2014 · 17,715 accessesView PDFCite
Research ArticleOpen accessIn the abstractComputer Machine Vision Inspection on Printed Circuit Boards Flux DefectsAng TeohOng, Zulkifilie Bin Ibrahim, Suzaimah RamliThe new visual inspection systems techniques using real time machine vision replace the human visual manual inspection on PCB flux defects, which brings harmful effects on the board which may come in the form of corrosion and can cause harm to the assembly. In short, it brings improvement in Printed Circuit Boards (PCB) production quality, principally concerning the acceptance or … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 3 · 28 Aug 2013 · 7,958 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Investigation of Factors Influencing Design Team Attributes in Green BuildingsMohamed S. Elforgani, Ismail RahmatProblem statement: Buildings contribute significantly global environmental problems. Better design can minimize these impacts. Design Green Building (DGB) aims to reduce buildings' impact on the environment. However, the green design performance depends on design team attributes. In addition, the Governance System (GS) and Client Quality (CQ) as external factors have influence on Design Team Attributes (DTA) of green building. Approach: … …American Journal of Applied Sciences, Vol. 7, Issue 7 · 31 Jul 2010 · 7,968 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimulation of Vegetative Induced Deformation in an Unsaturated SoilNazri Bn Ali, Mu’azu Mohammed AbdullahiProblem statement: Tree root water-uptake increases soil strength by increasing the soil matric suction due to pore pressure dissipation in a soil mass, inducing increases in vertical total stress or water extraction, the effective stress to which the soil strata is subjected to may also increase. This causes volume change which might be detrimental to geotechnical structures and shallow foundation. … …American Journal of Environmental Sciences, Vol. 6, Issue 2 · 30 Apr 2010 · 7,139 accessesView PDFCite
