Research ArticleOpen accessIn the abstractAn Alternative Scaling Factor In Broyden's Class Methods for Unconstrained OptimizationMuhammad Fauzi bin Embong, Mustafa bin Mamat, Mohd Rivaie, Ismail bin MohdProblem statement: In order to calculate step size, a suitable line search method can be employed. As the step size usually not exact, the error is unavoidable, thus radically affect quasi-Newton method by as little as 0.1 percent of the step size error. Approach: A suitable scaling factor has to be introduced to overcome this inferiority. Self-scaling Variable Metric algorithms … …Journal of Mathematics and Statistics, Vol. 6, Issue 2 · 2 Jun 2010 · 7,692 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy of Performance Parameters of Threshing Unit in a Single Plant ThresherEzzatollah Askari Asli-Ardeh, Yousef Abbaspour-Gilandeh, Saeid AbbasiProblem statement: The rice is the one of important crop in the word which is cultivated at the extensive area of Iran. Yield of crop is a factor which is investigated in the breading researches. Usually, for threshing of crops at these studies, single plant thresher is used. Approach: In this study, the threshing unit of a type of single … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 2 · 30 Jun 2009 · 8,531 accessesView PDFCite
Research ArticleOpen accessIn the abstractControl Strategy for Discontinuous Conduction Mode Boost Rectifier with Low Total Harmonic Distortion and Improved Dynamic ResponseH.S. AthabDue to its simplicity, the discontinuous conduction mode boost rectifier is potentially the least expensive active line-harmonics reducing circuit. Problem statement: The line current however, shows considerable distortion when the peak input voltage is close to the output voltage, As a result, the input power factor is poor. This study proposes a simple, low-cost method to reduce the line harmonics. … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 7,418 accessesView PDFCite
Research ArticleOpen accessIn the abstractArchitectural Review of Load Balancing Single System ImageB. S. Ahmed, K. Samsudin, A. R. RamliProblem statement: With the growing popularity of clustering application combined with apparent usability, the single system image is in the limelight and actively studied as an alternative solution for computational intensive applications as well as the platform for next evolutionary grid computing era. Approach: Existing researches in this field concentrated on various features of Single System Images like file system … …Journal of Computer Science, Vol. 4, Issue 9 · 30 Sep 2008 · 8,628 accessesView PDFCite
Research ArticleOpen accessIn the abstractSingle Stuck-At Fault Diagnosing Circuit of Reed-Muller Canonical Exclusive-Or Sum of Product Boolean ExpressionsP. N. Neelakantan, A. E. JeyakumarA testable design with a universal test set for single stuck-at zero and stuck-at one faults of Reed-Muller canonical form of Exclusive-OR sum of product logic expressions is proposed. The test circuit detects almost all the single stuck-at faults and needs only simple modifications for variations in the circuit under test. The number of test vectors is also quite small … …Journal of Computer Science, Vol. 2, Issue 7 · 31 Jul 2006 · 6,587 accessesView PDFCite
Research ArticleOpen accessIn the abstractModeling and Simulation of a Novel Switched Reluctance Motor Drive System with Power Factor ImprovementG. Venkatesan, R. Arumugam, M. Vasudevan et al.This study presents a novel Switched Reluctance Motor (SRM) drive system with power factor improvement. Recently, many of the converters with variable speed drives have no input power factor correction circuits. This results in harmonic pollution of the utility supply, which should be avoided. The effect of power factor variation in terms of harmonic content is also analyzed in this … …American Journal of Applied Sciences, Vol. 3, Issue 1 · 31 Jan 2006 · 7,096 accessesView PDFCite
Research ArticleOpen accessIn the abstractAntibiogram-Derived Radial Decision Trees: An Innovative Approach to Susceptibility Data DisplayRocco J. Perla, Paul P. BelliveauHospital antibiograms (ABGMs) are often presented in the form of large 2-factor (single organism vs. single antimicrobial) tables. Presenting susceptibility data in this fashion, although of value, does have limitations relative to drug resistant subpopulations. As the crisis of antimicrobial drug-resistance continues to escalate globally, clinicians need (1) to have access to susceptibility data that, for isolates resistant to first-line … …American Journal of Infectious Diseases, Vol. 1, Issue 2 · 30 Jun 2005 · 6,502 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of Growth Medium for Centella Asiatica Cell Culture Via Response Surface MethodologyRozita Omar, M. A. Abdullah, M. A. Hasan, M. MarziahThe effects of sucrose, Indole-3-Acetic Acid (IAA) and 6-BenzylAminoPurine (BAP) concentrations on cell growth of Centella asiatica cell suspension culture were studied. The concentrations were designed using Central-composite experimental design and regression analysis was carried out to obtain response surface model describing cell growth for prediction of optimum conditions. Only sucrose as a single factor was positively significant for cell … …American Journal of Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2004 · 7,204 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Flow Direction on Vortex Flow Structure, Heat Transfer and Performance Improvement in Tube with V-Discreted BafflesWithada Jedsadaratanachai, Amnart BoonloiNowadays, the compact heat exchanger is used widely like a radiator, evaporator and condenser of air condition system, cooling device of electronic. Extensive studies have been done on the heat transfer characteristics and flow structure for the heat exchanger with longitudinal vortex generators by numerical method. Periodic laminar flow and heat transfer characteristics in a three-Dimensional (3D) isothermal circular tube … …American Journal of Applied Sciences, Vol. 11, Issue 11 · 7 Jan 2015 · 6,714 accessesView PDFCite
Research ArticleOpen accessIn the abstractPolymorphisms in the 5’ Flanking Region and First Exon of Insulin-Like Growth Factor 1 Gene in Southern Populations of BuffaloSaber Khederzadeh, Ahmad YazdanpanahThe Insulin-like Growth Factor 1 (IGF-1) system plays a critical endocrine role controlling nutrient metabolism in animals and it is a group of structurally-related polypeptides that regulate the growth of many types of mammalian cells. In liver, IGF-1 is dynamically regulated by lactation and energy balance. Less is known about the regulation of IGF-1 and IGF-binding protein mRNA in reproductive … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 3 · 21 Sep 2013 · 6,846 accessesView PDFCite
