Research ArticleOpen accessIn the keywordsInvestigating Effects of Water Conditioning on the Adhesion Properties of Crack SealantAhmed Lamarre, Elham H. Fini, Taher M. Abu-LebdehThis paper investigates the effect of water exposure on three different crack sealants commonly used in cold, moderate and hot climates. It is hypothesized that water penetrates into the interface between crack sealant and substrates causing progressive adhesion failure and that the rate of failure varies depending on the sealant’s surface chemistry as relates to its interaction with water molecules … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 14 Mar 2016 · 8,778 accessesView PDFCite
Research ArticleOpen accessIn the keywordsRobust Electronic Differential Controller for an Electric VehicleA. Ravi, Sankaran PalaniThis study presents an efficient and robust control scheme of electronic differential system for an electric vehicle. The proposed system consists of two Brushless DC motors (BLDC) that ensure the drive of the two back driving wheels of an electric vehicle. Electronic Differential Controller (EDC) ensures the maximum torque and it can control both the driving wheel independently to turn … …American Journal of Applied Sciences, Vol. 10, Issue 11 · 10 Sep 2013 · 7,793 accessesView PDFCite
Research ArticleOpen accessIn the keywordsCorrelation Between Dispersion and Mean Toassess Healthcare Servicee FficiencyRamalingam ShanmugamMotivation for this research work started while helping a hospital administrator to assess whether patient oriented activity duration, X≥0 is reflecting the service’s efficiency? Higher value of the sample mean duration, X implies lesser productivity in the hospital and more healthcare cost. Likewise, larger value of sample dispersion, sx2 in the service durations is an indicator of lesser reliability and … …Current Research in Biostatistics, Vol. 2, Issue 2 · 30 Aug 2012 · 6,873 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAbsolute Flux Comparison of Magnetospheric ParticlesMiah M. AdelProblem statement: The calculation of magnetospheric particle flux by dividing the particle count rate by the instrument geometric factor does not take into account the anisotropic pitch angle distribution function. A comparison of particle fluxes measured by different instruments fail to lead to the right comparison. To circumvent the omission of anisotropy of the pitch angle distribution and to make … …Physics International, Vol. 3, Issue 1 · 26 Mar 2012 · 7,674 accessesView PDFCite
Research ArticleOpen accessIn the keywordsTransient Response of a Novel Displacement Transducer for Magnetic Levitation SystemMrunal Deshpande, Badrilal MathurProblem statement: In magnetic levitation system, position sensors are used to obtain a voltage proportional to the position of the suspended object. This is an essential feedback signal for stabilizing the system. These sensors make the system clumsy and prone to failures. To eliminate any physical attachment on the levitated object for the purpose of measuring its displacement, a novel … …American Journal of Applied Sciences, Vol. 8, Issue 11 · 5 Oct 2011 · 7,235 accessesView PDFCite
