Research ArticleOpen accessIn the abstractArtificial Neural Network Based Rotor Capacitive Reactance Control for Energy Efficient Wound Rotor Induction MotorK. Ranjith Kumar, S. Palaniswami, K. Siva KumarProblem statement: The Rotor reactance control by inclusion of external capacitance in the rotor circuit has been in recent research for improving the performances of Wound Rotor Induction Motor (WRIM). The rotor capacitive reactance is adjusted such that for any desired load torque the efficiency of the WRIM is maximized. The rotor external capacitance can be controlled using a dynamic … …Journal of Computer Science, Vol. 8, Issue 7 · 26 May 2012 · 7,166 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Dietary Kaempferia parviflora on Ischemic Brain Injury in the ratWathita Phachonpai, Sinthuporn Maharun, Supaporn Muchimapura et al.Problem statement: Stroke often causes irreversible neuronal damage and related behavioral deficits. The lack of effective and widely applicable pharmacological treatments for ischemic stroke patients may explain a growing interest in traditional plant medicines. We investigated the ability of consuming Kaempferia parviflora extract, a Thai medicinal plant reputed for neuroprotective effects against brain damage, reduced infarct volume and improve neurological … …OnLine Journal of Biological Sciences, Vol. 12, Issue 1 · 20 Mar 2012 · 9,095 accessesView PDFCite
Research ArticleOpen accessIn the abstractTheater Activities for Jung Opera Audience: An Educational UrgencyElita MauleProblem statement: Numerous studies have led researchers to conclude that the socio-demographic profile of the public of classical music appears to be quite generalizable. However, the survey of the opera public, a classical music subgenre that is often associated with theater performances, appears to be much more difficult to quantify and has not yet been the subject of specific investigations … …Journal of Social Sciences, Vol. 8, Issue 2 · 21 Feb 2012 · 8,936 accessesView PDFCite
Research ArticleOpen accessIn the abstractSliding Mode Observer-Based Fault Reconstruction for Uncertain Linear SystemsSlim Dhahri, Faycal Ben Hmida, Anis SellamiProblem statement: Fault reconstruction scheme is different from the majority of Fault Detection and Isolation (FDI) methods described in the literature in the sense that it not only detects and isolates the fault, but provides an estimate of the fault. This approach is very useful for incipient faults and slow drifts, which are very difficult to detect. Also, this approach … …American Journal of Applied Sciences, Vol. 8, Issue 10 · 8 Sep 2011 · 7,354 accessesView PDFCite
Research ArticleOpen accessIn the abstractSome Statistical Solutions and Methods in Evaluation of Efficiency in Sport and Effectiveness in the Phenomenon of Sportsmen' TrainingGheorghe Săvoiu, Ion Iorga, Marian Creţu, Ion MihăilăProblem statement: A general method for evaluation of efficiency in sport and effectiveness in the phenomenon of sportsmen’s training was proposed. Approach: The method of four “E” was a frame method focused on communication and evaluation, where efficiency acquired an essential importance and its variation related to the initial programme, with its time or space details, respectively related to the … …Journal of Social Sciences, Vol. 7, Issue 3 · 18 Jul 2011 · 7,881 accessesView PDFCite
Research ArticleOpen accessIn the abstractContributions Concerning Muscle Training in Professionnal VolleyballNiculescu Mugurel, Niculescu Ionela, Amzăr Elena LuminiţaProblem statement: Complex muscle training, less known to our specialists, has proved that, by complying with all the stages proposed, high level results may be achieved. The performances, weaker and weaker, obtained by the Romanian teams call for measures of optimization and Specific Physical Training (SPT) in accordance to technical -tactical training. Physical training should be individualized and multiplied, under … …Journal of Social Sciences, Vol. 7, Issue 3 · 16 Jul 2011 · 7,315 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhysicochemical and Microbial Caracteristics Performency in Wastewater Treated Under Aerobic ReactorAsma Ben Rajeb, Hamadi Kallali, Neila Saidi et al.Problem statement: The current work study the efficiency of biological wastewater treatment by an aerobic reactor which could be used in small agglomerations. RBC reduced physicochemical and microbiological load of wastewater but values remain above Tunisian standard. Approach: Experiments were conducted on a sand filled PVC column fed with wastewater treated by Rotating Biological Contactor (RBC) at a pulsed rhythm … …American Journal of Environmental Sciences, Vol. 7, Issue 3 · 11 Jul 2011 · 6,681 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of a Dual-Purpose Chemical Applicator for Paddy FieldsMohammed Shu’aibu Abubakar, Desa Ahmad, Othman Jamarei et al.Problem statement: One of the major problems of rice production is the shortage of labor resulting from migration from rural to urban areas, making it very difficult to meet peak demands for paddy production. In most developing countries of Southeast Asia, agricultural mechanization of paddy field operation is mostly carried out using conventional machines. For example in rice production powerintensive … …American Journal of Applied Sciences, Vol. 8, Issue 4 · 18 Apr 2011 · 7,545 accessesView PDFCite
Research ArticleOpen accessIn the abstractReliability Equivalence Factors of a System with m Non-Identical Mixed of LifetimesAbdelfattah Mustafa, Adel A. El-FaheemProblem statement: The aim of this study is to generalize reliability equivalence technique to apply it to a system consists of m independent and non-identical lifetimes distributions, with mixed failure lifetimes f1(t),f2(t),…,fm(t). Approach: We shall improve the system by using some reliability techniques: (i) reducing the failure for some lifetimes; (ii) add hot duplication component; (iii) add cold duplication component; … …American Journal of Applied Sciences, Vol. 8, Issue 3 · 25 Mar 2011 · 7,306 accessesView PDFCite
