Research ArticleOpen accessAll words, across the recordMOTIONS STUDY OF A SINGLE CYLINDER HIGH SPEED SPARK IGNITION LINIER ENGINE WITH SPRING SYSTEM AS RETURN CYCLEA. Z.M. Fathallah, Semin, I. M. Ariana, I. GeriantoA single cylinder two stroke spark ignition conventional engine have been modified to linier engine with spring mechanism. Before develop the design of linear engine is necessary to analysis of motion. Although principle of combustion process in combustion chamber is the same in fact the oscillation movement is different. Simulation technique has been adopted to study both linear and conventional … …American Journal of Applied Sciences, Vol. 11, Issue 3 · 17 Jan 2014 · 7,179 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordNitrogen Fixing Legumes in the Plant CommunitiesMohammed A.A. Al-FredanProblems statement: Numerous authors have used energetic to explain the ecological success of N-fixing plants. Legume biodiversity assessment, species dynamics, nitrogen fixation monitoring and environment impact assessment of these ecological events in Al-Hassa Oasis, Saudi Arabia are rare and need to be continuous and more frequent. Approach: Thus the objectives of this study were to analyze legume abundance within and … …American Journal of Environmental Sciences, Vol. 7, Issue 2 · 26 May 2011 · 7,400 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordThe Forces of a Simple Carrier ManipulatorRelly Victoria Virgil Petrescu, Raffaella Aversa, Taher M. Abu-Lebdeh et al.The present paper shows how to analytically determine the forces acting within a simple manipulator. Forces acting within any device or car have an important role because they are the ones that define the real movement of that device, the dynamic movement, movement that is very different from the cinematic imaginable by geometric-kinematic engineering calculations. To know the real movement … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 20 Feb 2018 · 7,224 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA Brief Tour into the History of Gravity: From Emocritus to EinsteinPanagiotis Papaspirou, Xenophon MoussasThe History of Gravity encompasses many different versions of the idea of the Gravitational interaction, which starts already from the Presocratic Atomists, continues to the doctrines of the Platonic and Neoplatonic School and of the Aristotelian School, passes through the works of John Philoponus and John Bouridan and reaches the visions of Johannes Kepler and Galileo Galilei. Then, the major … …Space Science International, Vol. 1, Issue 1 · 20 Jun 2013 · 15,084 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordV-Band Fade Dynamics Characteristics Analysis in Tropical RegionKhairayu Badron, Ahmad Fadzil Ismail, Jafri Din, Ahmad Tharek Abdul RahmanProblem statement: Satellite operations at V-band in tropical and equatorial regions are constrained as a result of attenuation from rain. Approach: Statistics for 20 consecutive months of V-band terrestrial link signal attenuation measurements in Malaysia were presented in this analysis. Such information was considered very pertinent for Earth-space communication link design and can be used for initial groundwork plan for … …American Journal of Applied Sciences, Vol. 7, Issue 8 · 31 Aug 2010 · 7,802 accessesView PDFCite
