Research ArticleOpen accessIn the abstractNew Analysis for The FGM Thick Cylinders Under Combined Pressure and Temperature LoadingK. Abrinia, H. Naee, F. Sadeghi, F. DjavanroodiAn analytical solution for computing the radial and circumferential stresses in a FGM thick cylindrical vessel under the influence of internal pressure and temperature is presented in this paper. It has been assumed that the modulus of elasticity and thermal coefficient of expansion were varying through thickness of the FGM material according to a power law relationship. Nevertheless the value … …American Journal of Applied Sciences, Vol. 5, Issue 7 · 31 Jul 2008 · 7,123 accessesView PDFCite
Research ArticleOpen accessIn the abstractPitch Angle Control of Variable Speed Wind TurbineYousif El-TousThe aim of this study is to design a simple controller to maximize the extracted energy of wind turbines. In this study the pitch angle control of variable speed wind turbine is investigated. In particular, it concentrates on the extraction of maximum available energy, reduction of torque and output power variations, which gives stresses in the gearbox and mechanical structure. … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 2 · 30 Jun 2008 · 8,735 accessesView PDFCite
Research ArticleOpen accessIn the abstractTrace Metal Mercury Levels in Residential Homes in KuwaitL. AL-Awadi, A. R. Khan, R. Al-KandariKuwait is an oil rich state on the northeastern corner of Arabian Peninsula and has faced the unprecedented man made environmental disaster in early 1991 of igniting over 600 oil wells those continually burnt for a period of over six months. The use of crude and heavy fuel oil in the power generating facilities has aggravated the pollution due to … …American Journal of Environmental Sciences, Vol. 4, Issue 1 · 29 Feb 2008 · 6,827 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment on Biocides Bioaccumulation in Mullet Liza klunzingeri in Kuwaiti Waters, off the Arabian GulfA.H. Bu-Olayan, B. V. ThomasBiocides, such as formaldehyde (HCHO), sodium hypochlorite (NaOCl) and glutaraldehyde (C5H8O2) that are commonly used in thermal, desalination and power plants and industries were tested on the commercially important mullet fish, Liza klunzingeri to determine the environmental contamination in the stressed ecosystem of Kuwait Bay sites. Multi-factor Probit analysis toxicity tests (96 h) on L. klunzingeri showed the lowest observed … …American Journal of Environmental Sciences, Vol. 2, Issue 3 · 30 Sep 2006 · 6,768 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA BIVARIATE PROBABILITY MODEL TO IDENTIFY "HONESTY" VERSUS "CHEATING" IN ECONOMIC SURVEYS: XENOPHOBIA IS ILLUSTRATEDRamalingam ShanmugamMaking successful policies for manufacturing or globalized business sectors require "honest" answers by the respondents in the surveys. When some respondents cheat in their answers to the questions in a survey for a variety of reasons, the survey results become useless. Currently, there is no appropriate probability model to address this phenomenon "cheating" in a survey. An efficient methodology is … …American Journal of Economics and Business Administration, Vol. 6, Issue 1 · 18 Jun 2014 · 6,849 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordModern Propulsions for the Aerospace IndustryRelly Victoria Virgil Petrescu, Raffaella Aversa, Antonio Apicella, Florian Ion Tiberiu PetrescuThis paper aims to contribute to the study of propulsion systems for modern aerospace vehicles with the obvious aim of improving them and to give them the ability to move much faster and easier in any direction, for a very long time, going through huge distances without the need of fuel refueling, as is the case with conventional, chemical propulsion. … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 12 May 2018 · 7,995 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordFrequency, Substance and Procedural Shortcomings of State Level Impeachment Campaigns in an Emerging Federal DemocracyIbraheem Oladipo MuheebNigeria’s 1999 Constitution encompasses separation of powers and checks and balances. It enjoins institutional autonomy in specific spheres, and systemic mutual inter-dependence of the legislature, executive and judiciary. The legislature has unfettered right to be self-regulatory including intra-institutional changes in leadership. Such right must be exercised responsibly and in conformity with the Constitution. Erring executive official could be impeached by … …Journal of Social Sciences, Vol. 12, Issue 2 · 17 Jun 2016 · 8,461 accessesView PDFCite

WahidabanuProblem statement: Since the advent of IC and VLSI technology, the demand for high-speed devices and equipment is growing very rapidly. Every individual researcher is marching towards the dream of achieving it. The role of a design engineer is becoming more challenging. As per Moore’s law, the packing density doubles every eighteen months. This is possible only by scaling down … …Journal of Computer Science, Vol. 8, Issue 4 · 1 Feb 2012 · 7,103 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordField Programmable Gate Array -Based System-on-Chip for Real-Time Power Process ControlAhmed Karim Ben Salem, Slim Ben Othman, Slim Ben SaoudProblem Statement: Nowadays Real-Time (RT) embedded control applications require not just higher performance but more flexibility as well without increasing cost and resources. Approach: In this study we presented a promising co-design and implementation of control solution. We developed flexible solution using software control algorithms coupled with an embedded RT kernel on powerful embedded processor cores, combined with reconfigurable logic … …American Journal of Applied Sciences, Vol. 7, Issue 1 · 31 Jan 2010 · 7,455 accessesView PDFCite
EditorialOpen accessAll words, across the recordAre we Able to Harness the Immunomodulatory Power of Cytokines for Novel Autoimmune Disease Treatments?Giuseppe Nocentini, Graziella Migliorati, Carlo RiccardiSince the end of the 1970s, interleukin 2 (IL-2) has been known as a key player in T cell expansion/activation (Watson et al., 1980). In the late 1980s, some groups used IL-2 to stimulate the immune systems of tumour patients (Jacobs et al., 1986). The idea seemed brilliant and several attempts were made, but the results were disappointing (Lim et … …American Journal of Pharmacology and Toxicology, Vol. 10, Issue 2 · 22 Oct 2015 · 7,625 accessesView PDFCite
