Research ArticleOpen accessEvery word in the titleThe Effect of Bone Properties due to Skeletal Diseases on Stability of Cementless Hip StemsMohammed Rafiq Abdul Kadir, Nazri KamsahProblem statement: There are two types of implant fixation in hip joint replacement-cemented and cementless. The cemented types are, in general, more popular due to concerns of possible inability of cementless implants achieving maximum primary stability for bone integration. The concern is more significant in cases where there are major losses of cancellous bone stock and thinning of the trabeculae … …American Journal of Applied Sciences, Vol. 6, Issue 12 · 31 Dec 2009 · 7,171 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDesign of UPFC Controller Using Modified Bilinear Equation for Improving Transient StabilityMajid Nayeripour, Taher NiknamBased on the use of the modified bilinear equation for the unified power flow controller (UPFC), this paper proposes a new control strategy to improve the transient stability of power system. This control strategy is applied to shunt and series inverters of UPFC as the modulating signals at the operating point. This input signals are such that the derivative of … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 6,640 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Application of Multi-Agent Technology on Transient Stability Assessment of Iraqi Super Grid NetworkAfaneen A. Abood, Ahmed N. Abdalla, Shant K. AvakianThe aim of this research is improving the Iraqi control center's capabilities for monitoring and controlling the electrical network by adopting the properties of multi-agent technology to enhance power system transient stability. The idea was demonstrated by two agent's strategy, the first agent is a prediction one that will predict power system instability by a transient stability program using the … …American Journal of Applied Sciences, Vol. 5, Issue 11 · 30 Nov 2008 · 7,325 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePolitical Stability and Economic Growth in AsiaMuhammad Younis, Xu Xiao Lin, Yahya Sharahili, Santhirasegaram SelvarathinamThis study investigates the effects of various factors of political instability on economic growth in selected ten Asian economies during 1990-2005. Our empirical findings show a close relationship between political stability and economic growth. We have analyzed the data by using ordinary least squire econometrics methods, which conclude that 32.35 scores increasing of index of political stability leads to one … …American Journal of Applied Sciences, Vol. 5, Issue 3 · 31 Mar 2008 · 8,559 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleLinks between Dynamic Physical Systems and Operator Theory Issues Concerning Energy Balances and StabilityM. D.L. SenThis study relates the properties of operators with the well- known concepts of positive realness and passivity properties in dynamic systems and their associate transfer functions. Those concepts together with very close related ones are first examined from a physical point of view. Then, they are related to hyper-stability and properties of transfer functions while the hyper-stability theorem is revisited … …American Journal of Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2004 · 6,827 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMethodology to Analyze the Stability of Bench Marks Applied for Settling Measurements of Buildings FoundationAndréa de Seixas, José Roberto de SeixasIn this work, one type of vertical bench mark is presented for the realization of the Vertical Local Geodetic Network for the control and analysis of settling foundation elements. The revision of the previous norm NBR 6122/96 to the current norm NBR 6122/2010, contributed in Brazil to the obligation of the services of measurement of settlings in buildings with more … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 1 · 18 Mar 2020 · 7,150 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAsymptotic Stability of Unicycle-Like Robots: The Bessel’s ControllerAndrés G. GarcíaAsymptotic stability of unicycle-like robots proved to be involved due to Brockett's condition. By using a smooth, time-invariant controller constructed out of Bessel’s functions, in this paper unicycle-like robots are uniformly-exponentially stabilized to the origin. The pure feedback controller obtained provides closed-form trajectories with the possibility of a simple and feasible (hardware) non-linear observer construction from posture angle measurements solely. … …Journal of Mechatronics and Robotics, Vol. 4, Issue 1 · 17 Jan 2020 · 7,308 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFractional Reserve Banking and Price Stability: Evidence from Gulf Cooperation Council (GCC) CountriesOsman Sayid Hassan Musse, Abdelghani Echchabi, Hassanuddeen Abdul AzizThis study aims at investigating the possible influence of the current money creation process applied by the commercial banks through the fractional reserve system on the overall prices stability in the Gulf Cooperation Council (GCC) countries. The study uses yearly data spanning from 2008 through 2013 for Qatar, Kuwait, Oman, Saudi Arabia and United Arab Emirates and applies panel regression … …American Journal of Economics and Business Administration, Vol. 7, Issue 3 · 11 Aug 2015 · 7,098 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleINFLUENCE OF ELECTRON BEAM TREATMENT ON THE CRYSTALLIZATION AND THERMAL STABILITY OF LDPE/EPDM BLENDSBhuwanesh Kumar Sharma, Subhendu Ray Chowdhury, P. A. Mahanwar, K. S.S. SarmaThe effect of blend composition and Electron Beam (EB) irradiation on the crystallization and thermal behavior of Low Density Polyethylene (LDPE)/Ethylene-Propylene-Diene elastomer (EPDM) blends had been studied. Melting temperatures were found to remain unchanged upon variation of blend composition as well as irradiation dose. But the degree of crystallinity and Tc (crystallization temperature) were decreased with increase in EPDM content … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 3 · 17 Nov 2014 · 7,049 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCOMPARATIVE STUDY OF DIFFERENT KALMAN FILTER IMPLEMENTATIONS IN POWER SYSTEM STABILITYH. H. Goh, C. W. Tai, Q. S. Chua et al.Voltage stability and voltage collapse issues have in recent years begun to constitute an unpleasant warning to the operational security of power systems. Many techniques have been investigated in order to predict the point of voltage collapse. However, there are still several restrictions due to the insufficiency of current system state information. Accompanied by the commencement of the Phasor Measurement … …American Journal of Applied Sciences, Vol. 11, Issue 8 · 29 May 2014 · 7,197 accessesView PDFCite
