Research ArticleOpen accessIn the abstractWind Load Effects on Manufactured Home FoundationsRamesh K. Dhungana, Taher M. Abu-Lebdeh, Ellie H. FiniProblem statement: Manufactured homes are susceptible to hurricane damage. Each year, significant losses, in terms of fatalities and property damage, are reported. There is always a prevalent concern about lateral load resistance capacity of tie-down system of manufactured homes when subjected to windstorms. This study is performed to determine the effects of hurricane wind on manufactured homes’ foundations. Approach: A … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 4 · 25 Jan 2012 · 8,333 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigation of Abutment Displacement of a Full Height Integral Bridges in Dense Granule BackfillM. H. Alizadeh, A.R. Khalim Rashid, Zamri Chik, S. M. MirhosseinyProblem statement: In this study, the behavior of abutment wall in full height frame integral abutment bridges was investigated. It was seen that the effect of backfill soil resistance on behavior of abutment wall movement is mostly neglected in previous studies. In this research, the final bridge superstructure displacement under temperature-induced forces was formulated. In addition, according to the final … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 30 Nov 2010 · 8,357 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Approach in Design and Operating Principle of Silicone Tactile SensorBakri Ali, Rozaini Othman, Rasdi Deraman, Muhammad Azmi AyubProblem statement: Research and development in tactile sensor are escalating due to the fact that advanced robot needs to interact with surrounding environments which is very complex, dynamic, uncontrolled and difficult to perceive reliably. Recent research has been focusing in development of new tactile sensor that takes advantage of advances in materials, Micro-Electromechanical Systems (MEMS) and semiconductor technology. To date, … …Journal of Computer Science, Vol. 6, Issue 8 · 31 Aug 2010 · 7,353 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of a Wall Climbing RobotSurachai PanichProblem statement: The problem of a wall climbing robot is holding on the wall. This is challenge for researchers. There are many factors, which effect in holding, all forces, robot movement and mechanical design. Approach: This study proposed movement step design for wall-climbing robot. In design the robot use pneumatic system as main unit to move on the wall. The … …Journal of Computer Science, Vol. 6, Issue 10 · 10 Aug 2010 · 7,861 accessesView PDFCite
Research ArticleOpen accessIn the abstractInteraction of Soil Static and Dynamic Stiffness and Buried Pipeline Under Harmonic VibrationAlireza Mirza Goltabar Roshan, Hossein Khalilpasha, Mohsen GhorbaniProblem statement: When earthquake is occur, many damages were occurred in pipelines that San Francisco (1906) and Manson (1908), Kobe (Japan) and ate are samples of this topic. So many researchers studied on the pipelines and dynamic forces. Approach: Determine static and dynamic performance parameters of the pipeline and the surrounding soil such as static stiffness, dynamic stiffness, damping and … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 7,733 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment and Evaluation of Tractors and Tillage Implements Instrumentation SystemS. A. Al-Suhaibani, A. A. Al-Janobi, Y. N. Al-MajhadiProblem statement: Field machines contribute a major portion of the total cost of crop production. Proper selection and matching of farm machinery is essential in order to reduce the cost of crop production. Performance data for tractors and implements are, therefore, essential for farm machinery operators and manufacturers alike. The aim of this study was to develop and evaluate an … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 8,313 accessesView PDFCite
