Research ArticleOpen accessIn the abstractImpulse Volt-Time Characteristics of Oil and OIP InsulationS. Venkatesan, S. UsaEstimation of insulation strength of transformer oil and Oil Impregnated Paper (OIP) insulation, which constitutes major portion of insulation in power transformer, is an important task. Also, it is often necessary to evaluate the breakdown strength of oil and OIP under non-standard impulse voltages, since the oil and OIP insulation is subjected to non-standard waveshapes between inter-disc and inter-turn insulation. … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 7,241 accessesView PDFCite
Research ArticleOpen accessIn the abstractProduction of Cellulase from Oil Palm Biomass as Substrate by Solid State BioconversionMd. Z. Alam, Nurdina Muhammad, Mohd E. MahmatSolid state bioconversion (SSB) of lignocellulosic material oil palm biomass (OPB) generated from palm oil industries as waste was conducted by evaluating the enzyme production through filamentous fungus in lab-scale experiment. OPB in the form of empty fruit bunches (EFB) was used as the solid substrate and treated with the fungus Trichoderma harzianum to produce cellulase.

Research ArticleOpen accessIn the abstractMathematical Modeling of Wastewater Oxidation under Microgravity ConditionsBoyun Guo, Donald W. Holder, David S. SchechterVolatile removal assembly (VRA) is a module installed in the International Space Station for removing contaminants (volatile organics) in the wastewater produced by the crew. The VRA contains a slim pack bed reactor to perform catalyst oxidation of the wastewater at elevated pressure and temperature under microgravity conditions. Optimal design of the reactor requires a thorough understanding about how the … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 6,888 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of Ecological Criteria of Noise Control With Application of AbsorbentsM. A. Al-NawaflehThe operation conditions of the industrial equipment, acoustic parameters essentially depend on type of the sound field (free, diffuse or mixed). Besides the effect of the noise control of the machine itself, the field type also important, which in turn depends on the degree and quality of acoustic preparation of the workshop. The criteria is an estimation of applicability broadband … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 6,805 accessesView PDFCite

Research ArticleOpen accessIn the abstractRobust Outlier Detection in Linear RegressionNethal K. Jajo, Xizhi WuNew methodology of robust outlier detection based on Robustly Studentized Robust Residuals (RSRR) examination is well established in linear regression analysis. Two new robust location estimators of linear regression parameters are developed in simple and multiple cases. Based on these robust estimators we obtain RSRR. We used RSRR to derive a new measure of distance to be used in outlier … …American Journal of Applied Sciences, Vol. 1, Issue 2 · 30 Jun 2004 · 6,933 accessesView PDFCite
