Research ArticleOpen accessEvery word in the titlePERFORMANCE ANALYSIS OF ANTI-COLLISION ENABLED ROBOT USING HYBRID BEACON SCHEDULING APPROACHP. Prabakaran, M. SaravananIn multi-robot environment, when many robots are moving in the same workspace, there is a possibility of their physical collision with themselves as well as with physical objects. In this study, hybrid beacon scheduling protocol is proposed and for avoiding such collisions in robotic mobile environment with low latency and power consumption. The purpose of deploying this protocol is to … …American Journal of Applied Sciences, Vol. 11, Issue 5 · 6 Mar 2014 · 6,449 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA SHORT INTERFERING RNA MOLECULAR BEACON FOR THE ATTENUATION OF MYCOBACTERIAL INFECTIONRemo George, Kathy Nugent, Norman Bolus et al.The ability of the pathogen Mycobacterium Tuberculosis (MTB) to invade and survive within macrophages of granulomas is attributed to the product of the Mammalian Cell Entry (MCE) operon whose gene, mce4A, encodes a cholesterol transporter that transports host lipids into the bacterium that allows the bacterium to survive during chronic infection. Here, we proposed and tested the hypothesis that a … …American Journal of Biochemistry and Biotechnology, Vol. 10, Issue 1 · 4 Mar 2014 · 7,774 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSELECTION OF BEAUVERIA BASSIANA (BALSAMO) VUILLEMIN ISOLATES FOR MANAGEMENT OF MYZUS PERSICAE (SULTZAR) (HOM.: APHIDAE) BASED ON VIRULENCE AND GROWTH RELATED CHARACTERISTICSMohammad S. Al-alawi, Maher ObeidatIsolates of the entomopathogenic fungus Beauveria bassiana originated from Jordan were evaluated for their efficacy against the green peach aphid, Myzus persicae under laboratory and greenhouse conditions. Efficacy evaluation involved testing all isolates at a concentration of 1×107 conidia/mL followed by concentration dependent and greenhouse bioassays for the top virulent isolates. Growth characteristics related to virulence were evaluated for high, … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 1 · 28 Dec 2013 · 7,943 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRobust Positioning of Laser Beams Using Proportional Integral Derivative and Based Observer-Feedback ControlKwabena A. Konadu, Sun Yi, Wonchang Choi, Taher Abu-LebdehHigh-precision positioning of laser beams has been a great challenge in industry due to inevitable existence of noise and disturbance. The work presented in this study addresses this problem by employing two different control strategies: Proportional Integral Derivative (PID) control and state feedback control with an observer. The control strategies are intended to stabilize the position of a laser beam … …American Journal of Applied Sciences, Vol. 10, Issue 4 · 19 Apr 2013 · 6,868 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Use of Swimmer Bars as Shear Reinforcement in Reinforced Concrete BeamMoayyad Al-Nasra, Naem Asha, Abdelqader Najmi, Taher Abu-LebdehThe behavior of reinforced concrete beams at failure by shear is distinctly different from their behavior by bending, which is considered to be unsafe mode of failure. The shear failure of beams is usually sudden without sufficient advanced warning and the diagonal cracks that develop due to excess shear forces are considerably wider than the flexural cracks. The cost and … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 1 · 15 Mar 2013 · 8,134 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDynamic Response of Loads on Viscously Damped Axial Force Rayleigh BeamI. A. Adetunde, Baba SeiduThis research examines the effects of moving loads on viscously damped axial force Rayleigh beam. The authors especially tried to find the effect of the moving mass and moving force in connection with the length of the span of a Rayleigh beam. The authors also examined the effect of the lengths of the beam and of the load. It was … …American Journal of Applied Sciences, Vol. 5, Issue 9 · 13 Aug 2012 · 6,579 accessesView PDFCite

Research ArticleOpen accessEvery word in the titleA Simplified Two-Dimentional Unit Cell Model for Analyzing the Transverse Shear Stiffness of Three-Dimentional Truss-Like Core Sandwich BeamSuphattharachai Chomphan, Manit LeekitwattanaProblem statement: In structural analysis using finite element software, a complex three-dimensional model affects the speed of calculation time. A simplified two-dimensional model should be used for analyzing structural responses to reduce the calculation time. Approach: This study presents a study on the analysis of the transverse shear stiffness of three-dimensional truss-like core sandwich beam using a simplified two-dimensional unit … …American Journal of Applied Sciences, Vol. 9, Issue 2 · 26 Dec 2011 · 7,176 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSungai Mas and OC-EO Glass Beads: A Comparative StudyZuliskandar Ramli, Nik Hassan Shuhaimi Nik Abd. Rahman, Adnan JusohProblem statement: Sungai Mas, Kedah, Malaysia and OC-EO, Vietnam, was two of the Indo-Pacific beads making centre’s in Southeast Asia. The drawn monochrome glass beads or Indo-Pacific beads industry begun in Arikamedu, India since 200BC was identified by Ptolemy as Poduca Emporium, with the presence of a small colony of Roman merchants. Arikamedu was abandoned by the 3rd century and … …Journal of Social Sciences, Vol. 8, Issue 1 · 28 Oct 2011 · 8,491 accessesView PDFCite
