Research ArticleOpen accessIn the abstractDesign of Flywheel with a Moving HoleJihad Said AddasiA special apparatus has been designed to study linear, circular, and rotational motions. This apparatus consists of a flywheel, rotating in horizontal plane by the mean of a hanging mass. This flywheel carries a hole, which can be moved on a radial rail. This hole can be fixed at desired distance from the flywheel axis. Putting a metallic sphere on … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 6,890 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Successful Industrial Academic Cooperation, Development of Closed-cell Metallic FoamsSheng-Chung Tzeng, Chu-Wei Lin, Wei-Ping MaThis investigation proposes a successful case of industrial-academic cooperation between the Chienkuo Technology University and J. King Aluminum Inc. This study was proposed by the rotating machinery and heat transfer laboratory. They studied the optimal heat transfer and structural strength of closed-cell aluminum porous material. The cooperation involved the exchange of technical skills; the determination of policies and methods for … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 6,892 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpectrometric Methods Used to Determine Heavy Metals and Total Cyanides in Accidental Polluted SoilsA. Mihaly-Cozmuta, L. Mihal Cozmuta, V. Viman et al.The study presents the level of soil pollution in the area adjacent to three sedimentation ponds as a result of an environmental accident. Soil samples from various sites have been collected and analyzed to determine the concentration of heavy metals (Cu, Pb, Zn) and total cyanides. The analysis methods used were ICP-AES for heavy metals and the colorimetric for total … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 6,912 accessesView PDFCite
Research ArticleOpen accessIn the abstractExtending UML-RT for Control System ModelingQimin Gao, L. J. Brown, L. F. CapretzThere is a growing interest in adopting object technologies for the development of real-time control systems. Several commercial tools, currently available, provide object-oriented modeling and design support for real-time control systems. While these products provide many useful facilities, such as visualization tools and automatic code generation, they are all weak in addressing the central characteristic of real-time control systems design, … …American Journal of Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2004 · 6,746 accessesView PDFCite
Research ArticleOpen accessIn the abstractFourier Series With Spectral and Wave Number DecompositionJung-Hua Chou, Raylin WuIn this study, the generic nature of Fourier series is pointed out and the requirement of dimensional homogeneity for physical systems is emphasized. By suitable application of non-dimensional variables, both time versus frequency and spatial versus wave number decomposition of Fourier series are included properly to put the physics involved into the right physical meanings. Furthermore, the high frequency noise … …American Journal of Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2004 · 7,253 accessesView PDFCite
