Research ArticleOpen accessIn the keywordsFujisaki’s Model of Thai’s Fundamental Frequency Contours with Environmental NoisesSuphattharachai Chomphan, Chutarat ChompunthProblem statement: An important human speech feature is the fundamental frequency (F0) contour which represents the speech prosody. It indicates the naturalness and intelligibility of the speech. Modeling of fundamental frequency contour was an essential procedure in the natural speech processing. In speech communication, environmental noise plays an essential role in damaging the digital communication quality. The study of effects … …American Journal of Applied Sciences, Vol. 9, Issue 8 · 28 Jun 2012 · 7,284 accessesView PDFCite
Research ArticleOpen accessIn the keywordsComparative Performance Evaluation of Routing Algorithms in IEEE 802.15.4 and IEEE 802.11 with Different Ad Hoc Routing ProtocolP. Anitha, C. ChandrasekarProblem statement: Wireless ADHOC networks are self organized dynamic networks can share wireless channel without any established central control standard for IEEE 802.11. Approach: The most common protocols are AODV, DSDV, DSR in ADHOC used to ensure the data transmission among themselves. To meet the need of low power and low cost IEEE 802.15.4 standard was developed for sensor networks. … …Journal of Computer Science, Vol. 7, Issue 5 · 7 May 2011 · 7,409 accessesView PDFCite
Research ArticleOpen accessIn the keywordsBootstrap Method for Dependent Data Structure and Measure of Statistical PrecisionT. O. Olatayo, G. N. Amahia, T. O. ObiladeProblem statement: This article emphasized on the construction of valid inferential procedures for an estimator θ^ as a measure of its statistical precision for dependent data structure. Approach: The truncated geometric bootstrap estimates of standard error and other measures of statistical precision such as bias, coefficient of variation, ratio and root mean square error are considered. Results: We extend it … …Journal of Mathematics and Statistics, Vol. 6, Issue 2 · 30 Jun 2010 · 7,258 accessesView PDFCite
Research ArticleOpen accessIn the keywordsLinear Regression Model Selection Based on Robust Bootstrapping TechniqueHassan S. Uraibi, Habshah Midi, Bashar A. Talib, Jabar H. YousifProblem statement: Bootstrap approach had introduced new advancement in modeling and model evaluation. It was a computer intensive method that can replace theoretical formulation with extensive use of computer. The Ordinary Least Squares (OLS) method often used to estimate the parameters of the regression models in the bootstrap procedure. Unfortunately, many statistics practitioners are not aware of the fact that … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 7,876 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSerological Evaluation of Brucella abortus S99 Lipopolysaccharide Extracted by an Optimized MethodAli Sharifat Salmani, Seyed Davar Siadat, Mohammad Reza Fallahian et al.Problem statement: Brucellosis is a globally found infectious disease and there is no licensed vaccine against human brucellosis. The present study carried-out to evaluate the potency of our modified extracted lipopolysaccharide (LPS) of B. abortus to elicit specific anti-Brucella antibodies in animal model (Rabbit) as a part of a candidate vaccine for brucellosis. Lipopolysaccharide is one of the main virulence … …American Journal of Infectious Diseases, Vol. 5, Issue 1 · 31 Mar 2009 · 9,080 accessesView PDFCite
Research ArticleOpen accessIn the keywordsStudy of Families of Curves in the Euclidian PlanBelaib Lekhmissi, Bouarroudj Nadra, Hocine El HabibNon-standard analysis techniques are more considered in approaching complex mathematical domains. By using some concepts of non-standard analysis methods such as regionalization method, we deal with a family of curves in an Euclidian plan. The solutions of the algebraic equations representing these curves in a plan have an hyperbolic forms. …Journal of Mathematics and Statistics, Vol. 3, Issue 3 · 30 Sep 2007 · 6,834 accessesView PDFCite
Research ArticleOpen accessIn the keywordsComputer Arithmetic Algorithms for Mega-Digit Floating Point Numbers' PrecisionMusbah J. Aqel, Mohammed H. SalehIEEE standard 754 floating point is the most common representation used for floating point numbers, and many computer arithmetic algorithms are developed for basic operations on this standard. In this study, new computer algorithms are proposed to increase the precision range and to solve some problems that are available while using these algorithms. However, these algorithms provide an optional range … …Journal of Computer Science, Vol. 3, Issue 2 · 28 Feb 2007 · 6,649 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAutomatic Identification of Molecules in a Thin-Film Extract Combined with LaserTheodore Guié Toa Bi, Sié Ouattara, Alain ClementThis paper presents the automation of the thin-layer chromatography technique whose separation and identification of molecules present in a mixture are currently done manually and laboriously. We have therefore found an interest in automating this technique. In this part, the method implemented comprises 2 steps. First we proceeded to the segmentation of the spots obtained on the chromatographic plate. We … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 4 · 14 Nov 2018 · 7,089 accessesView PDFCite
Research ArticleOpen accessIn the keywordsMuon Anomalous Magnetic Moment in a SU(4) ⊗ U(1)N Model Without Exotic Electric ChargesDiego CogolloWe study an electroweak gauge extension of the standard model, so called 3-4-1 model, which does not contain exotic electric charges and it is anomaly free. We discuss phenomenological constraints of the model and compute all the corrections to the muon magnetic moment. Mainly, we discuss different mass regimes and their impact on this correction, deriving for the first time … …Physics International, Vol. 6, Issue 1 · 13 Sep 2015 · 7,687 accessesView PDFCite
Research ArticleOpen accessIn the keywordsRapid Real Time PCR Based Detection of Cell Count in Case of Urinary Tract InfectionPoulomi Nandy, Ashoke Ranjan Thakur, Shaon Ray ChaudhuriMicrobial identification and antimicrobial susceptibility testing methods currently used in clinical microbiology laboratories require at least two to three days because they rely on the growth and isolation of micro-organisms. This long, but necessary, delay has enormous consequences on prophylactic usage of antimicrobial drugs. This study was an attempt to reduce this detection time span. Taq Man Real Time PCR … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 2 · 22 Jun 2013 · 8,214 accessesView PDFCite
