Research ArticleOpen accessAll words, across the recordDynamic Reliability Analysis of Steel Moment Frames Using Monte Carlo TechniqueMajid Mahjoor Lotf AabadiDesigning of structures is the function of operation of them. However, operation of the structures depends on different uncertainties. In practical cases, uncertain parameters are simplified and formulated to certain parameters which are implemented in the designing approach. In this investigation, different structural parameters which bear with uncertainties including loading conditions, strength of materials and geometry of the structural elements … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 2 · 17 Jun 2019 · 7,681 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordNumerical Study on the Influence of Fault on the Seepage and Stress Field of FormationYongxiang Zheng, Jianjun Liu, Bohu Zhang, Yue SunIn the process of water injection in oil field, the fault will affect the seepage field and stress field of the formation, which leads to the deformation and destruction of the formation. Therefore, more casing damage wells are found around the fault. In order to study the influence of fault on the formation in the process of water injection, a … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 1 · 9 Feb 2017 · 7,344 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordVHDL Modeling, Simulation and Prototyping of a Novel Arbitrary Signal Generation SystemS. A. Abbasi, A. R.M. Alamoud, J.M. Al ShahraniProblem statement: Arbitrary signal generators play an important role in many applications. Several different techniques utilizing both analog and digital approaches are being used for the generation of periodic signals. However, all of them suffer from many drawbacks. In this study, we present modeling, simulation and prototyping of a novel periodic arbitrary signal generation system using FPGAs. The proposed system … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 5 Nov 2010 · 7,755 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordFlow Simulation in Engine Cylinder with Spring MeshM.H. Shojaeefard, A.R. NoorpoorThis investigation presents results from numerical simulation of the air flow in Spark Ignition Engine (SI engine) cylinder. Accurate modeling of the flow in cylinder is a key part of successful combustion simulation. The most usual numerical method in Computational Fluid Dynamics (CFD) is finite volume. In this investigation an important, common fluid flow patterns in CFD simulations, namely, Tumble … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 7,061 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordWind Speed Simulation Using WaveletsA. H. Siddiqi, S. Khan, S. RehmanMost of the renewable energy sources have direct or indirect link with the sun. Wind is also a form of solar energy. It is initiated by uneven heating of the atmospheric air by the sun, affected from the topography and surface roughness of the earth's surface and rotation of the earth. The earth's terrain, water surfaces and vegetation cover modifies … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 7,546 accessesView PDFCite

Research ArticleOpen accessAll words, across the recordUniform Twister Plane GeneratorAleksei F. Deon, Yulian A. MenyaevRandom plane generators may use various types of the random number algorithms to create multidimensional planes. At the same time, the discrete Descartes random planes have to be uniform. The matter is that using the concept of the uncontrolled random generation may lead to a result of weak quality due to initial sequences having either insufficient uniformity or skipping of … …Journal of Computer Science, Vol. 14, Issue 2 · 26 Feb 2018 · 11,514 accessesView PDFCite
