Research ArticleOpen accessIn the abstractDesign and Implementation of an Optimal Fuzzy Logic Controller Using Genetic AlgorithmS. Khan, S. F. Abdulazeez, L. W. Adetunji et al.All control systems suffer from problems related to undesirable overshoot, longer settling times and vibrations while going form one state to another state. Most of relevant techniques had been in the form of suggesting modification and improvement in the instrumentation or interfacing part of the control system and the results reported, remain suffering from shortcomings related to hardware parameter dependence … …Journal of Computer Science, Vol. 4, Issue 10 · 31 Oct 2008 · 8,051 accessesView PDFCite
Research ArticleOpen accessIn the abstractFeatures in Tubercular Meningoencephalitis Diagnosis: 18 Childhood CasesP. Di Carlo, D. Cabibi, A. Casuccio et al.The aim of this research is to illustrate clinical and instrumental features of central nervous system tuberculosis (CNS-TB) in childhood in order to allow prompt diagnosis and adequate patient management. TB remains one of the most important communicable diseases and represents a major global health problem. Although pulmonary TB tends to be the most common form of the disease, the … …American Journal of Infectious Diseases, Vol. 4, Issue 3 · 30 Sep 2008 · 6,793 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamic Measurement of Copper (II) Ion Adsorption in Activated Carbon Fixed Bed ColumnsTanokkorn Banjonglaiad, Eric Croiset, Peter Silveston et al.Dynamic experiments were carried out on the adsorption of copper (II) ions in a laboratory packed bed of activated carbon. Both pulse and step change inputs were used. Measurements were reproducible and replicate measurements furnished nearly identical parameters for a heterogeneous model of the activated carbon bed assuming Langmuir adsorption isotherm. The initial concentration of copper (II) ion was 3 … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 6,866 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Storage Time and Temperature on Serum AnalytesAbdoljalal MarjaniInformation on the measured concentration of serum analytes during storage of serum samples is often incomplete and sometimes contradictory. The 10 analytes have not studied in this area in healthy subjects. The aim of present study was designed to determine the effect of storage time and temperature on the laboratory results of 10 analytes in sera from apparently healthy adult … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 8,875 accessesView PDFCite
Research ArticleOpen accessIn the abstractMathematical Sophistication and Differentiated Emotions during Mathematical Problem SolvingBradford D. Allen, James CarifioGeorge Polya, author of Mathematical Discovery and the enduring best seller How to Solve It: A New Aspect of Mathematical Method, claims that more sophisticated people experience more differentiated emotion during mathematical problem solving, a claim that has been untested for nearly fifty years. Using instruments that measure ongoing evaluations and emotion in real time, and traits that reflect mathematical … …Journal of Mathematics and Statistics, Vol. 3, Issue 4 · 31 Dec 2007 · 7,579 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Monitoring of Energy Flow in the Power Transmission and Distribution System Using Grid ComputingC. Senthamarai, A. Krishnan, R. HemalathaGrid Computing is a promising infrastructure and technology that involves the integrated and collaborative use of Computers, networks, databases and scientific instruments owned and managed by multiple organizations. In this context our research primarily aims at developing an application framework for monitoring the Performance of Power Transmission and Distribution System using Grid Computing.

Research ArticleOpen accessIn the abstractHarmonic Elimination of Inverters using Blind Signal SeparationB. Justus Rabi, R. ArumugamHarmonics cause major problems in power system due to non linear loads. With the rapid growth in the utilization of the rectifier for critical loads, e.g. In computer or medical equipment the need for high quality uninterruptible power is increasing. The non-linear current drawn by the rectifier loads distort the output of UPS system. Mainly because of output filter impedance … …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 6,903 accessesView PDFCite
Research ArticleOpen accessIn the abstractIdentification, Characterization and Quantification of Elastomeric/Plastomeric Waste for Sustainable Waste MinimizationKajal Yadav, Sangita, A. ChandraThe present study focuses on the importance of characterization of waste/post consumer polymers. In recent years sophisticated instrumental techniques played an important role in identification and characterization of polymers. Advances in computer techniques have been combined with analytical instruments to give analytical speed, resolution and minimal sample requirements unimagined a few years ago. The present study deals with the development … …American Journal of Environmental Sciences, Vol. 1, Issue 3 · 30 Sep 2005 · 7,058 accessesView PDFCite
