Research ArticleOpen accessIn the abstractSociopolitical Instability and Economic Growth Empirical Evidence from Sri LankaChangsheng Xu, Santhirasegaram Selvarathinam, Wen Xing LiSociopolitical instability severely affects economic growth in short and long run. This study analyzes that sociopolitical instability measured by proxy measure; annual growth rate of tourist arrivals in Sri Lanka during 1960-2005 adversely affects economic growth. Our empirical findings based on ordinary lease square econometric estimation, show that sociopolitical instability negatively and significantly affect economic growth. Reduction of economic growth … …American Journal of Applied Sciences, Vol. 4, Issue 12 · 31 Dec 2007 · 6,881 accessesView PDFCite
Research ArticleOpen accessIn the abstractOpen Circuit Field Distribution and Induced Voltage of a Cylindrical Permanent Magnet Linear GeneratorWijono, Hamzah ArofThis paper deals with the analytical computation of the magnetic field of a cylindrical permanent magnet linear generator. It offers an alternative solution to the magnetic field problem. A new approach to solve Poisson equation using Struve function is introduced and it offers a simple but accurate analytical estimation to the calculation of the open circuit flux density and induced … …American Journal of Applied Sciences, Vol. 4, Issue 11 · 30 Nov 2007 · 7,194 accessesView PDFCite
Research ArticleOpen accessIn the abstractSample Selection Analysis of Wage Equation for Women In Ondo State NigeriaSola Olorunfemi, Olorunsola E. OlowofesoThe study analysis wage equation for women in Ondo State Nigeria, in other to identify the determinant factors of their wages. Data collected from 250 women heads of households through a multi-stage random system technique were analyzed. In order to deal with the zero wage problem associated with those who did not work, various single – equation models were applied. … …Journal of Social Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 7,563 accessesView PDFCite
Research ArticleOpen accessIn the abstractQuality Monitoring Using Principal Component Analysis and Fuzzy Logic Application in Continuous Casting ProcessSalah Bouhouche, Malek Lahreche, Abdelkrim Moussaoui, Jürgen BastThis paper deals with non linear system monitoring, based on a combined use of Principal Components Analysis (PCA) and fuzzy logic to process and quality monitoring. PCA coupled to fuzzy logic was used to estimate the fault or defect according to the dynamic changes in the process inputs-outputs characterized by T2 Hoteling and Squared Prediction Error (SPE). Correlation between the … …American Journal of Applied Sciences, Vol. 4, Issue 9 · 30 Sep 2007 · 7,245 accessesView PDFCite
Research ArticleOpen accessIn the abstractStop Conditions Of BB84 Protocol Via A Depolarizing Channel (Quantum Cryptography)Iyed Ben Slimen, Olfa Trabelsi, Houria Rezig et al.BB84 (Bennett and Brassard 1984) is one of the well known protocols of quantum keys distribution. It is built to allow two interlocutors commonly called Alice and Bob to share two similar binary keys and to detect the eavesdropper presence (the eavesdropper is commonly called Eve). However, Eve presence in a disturbed environment causes errors to the sifted keys and … …Journal of Computer Science, Vol. 3, Issue 6 · 30 Jun 2007 · 7,349 accessesView PDFCite
Research ArticleOpen accessIn the abstractIncome Distribution and Health Status: Econometric Evidence from OECD CountriesVasudeva N.R. MurthyThis research note, using a cross-sectional sample consisting of 27 Organization for Economic Co-operation and Development countries (OECD) for the reference year 2002, empirically examines the relationship between health status as measured by infant mortality and the degree of income inequality, given the effect of certain controlled variables. The empirical findings based on the estimation by robust econometric methods, show … …American Journal of Applied Sciences, Vol. 4, Issue 4 · 30 Apr 2007 · 7,254 accessesView PDFCite
Research ArticleOpen accessIn the abstractBounds Testing Approach to Cointegration: An Examination of Foreign Direct Investment Trade and Growth RelationshipsOteng Abayie Eric Fosu, Frimpong Joseph MagnusThis study examines the long-run impact of foreign direct investment and trade on economic growth in Ghana. Using an augmented aggregate production function (APF) growth model, we apply the bounds testing (ARDL) approach to cointegration which is more appropriate for estimation in small sample studies. The data span for the study is from 1970 to 2002. We found cointegration relations … …American Journal of Applied Sciences, Vol. 3, Issue 11 · 30 Nov 2006 · 9,336 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimal Parameter Tuning in a Predictive Nonlinear Control Method for a Mobile RobotD. Hazry, M. SugisakaThis study contributes to a new optimal parameter tuning in a predictive nonlinear control method for stable trajectory straight line tracking with a non-holonomic mobile robot. In this method, the focus lies in finding the optimal parameter estimation and to predict the path that the mobile robot will follow for stable trajectory straight line tracking system. The stability control contains … …American Journal of Applied Sciences, Vol. 3, Issue 4 · 30 Apr 2006 · 7,090 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdults' Demand for the Internet use in the USA: An Empirical ApproachIsmail H. Genc, Hasan Sahin, Robert W. StoneAcademic literature regarding the factors influencing Internet use is presented. Based on this literature, a theoretical model of the demand for the use of the Internet is developed. The estimation of the demand for Internet use in the U.S. is performed using logit and probit. The model includes explanatory variables such as gender, race, income, age, educational level, marital status, … …Journal of Mathematics and Statistics, Vol. 2, Issue 1 · 31 Mar 2006 · 6,858 accessesView PDFCite
Research ArticleOpen accessIn the abstractRisk Assessment Study for Storage ExplosiveS. Saiful Azhar, M. Abdul Rahman, M. Saari et al.In Malaysia, there has been rapidly increasing usage in amount of explosives due to widely expansion in quarrying and mining industries. The explosives are usually stored in the storage where the safety precaution had given high attention. As the storage of large quantity of explosive can be hazardous to workers and nearby residents in the events of accidental denotation of … …American Journal of Applied Sciences, Vol. 3, Issue 1 · 31 Jan 2006 · 7,102 accessesView PDFCite
