Research ArticleOpen accessIn the abstractSpeech Enhancement Algorithm Using Sub band Two Step Decision Directed Approach with Adaptive Weighting factor and Noise Masking ThresholdDeepa Dhanaskodi, Shanmugam ArumugamProblem statement: Speech Enhancement plays an important role in any of the speech processing systems like speech recognition, mobile communication, hearing aid. Approach: In this work, human perceptual auditory masking effect is incorporated into the single channel speech enhancement algorithm. The algorithm is based on a criterion by which the audible noise may be masked rather than being attenuated and … …Journal of Computer Science, Vol. 7, Issue 6 · 14 Jun 2011 · 7,126 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Technique for Quality Evaluation of E-Learning from Developers PerspectiveMajdi Abdellatief, Abu Bakar Md Sultan, Marzanah A. Jabar, Rusli AbdullahProblem statement: E-learning is gaining more acceptance as days pass because it provides learning opportunity any time and in any place. Different people have different preferences in terms of learning style such as reading text, listing audio or video, speaking and communication. To support these different learning preferences, there is need for multiple e-learning delivery methods and teaching techniques. Furthermore, … …American Journal of Economics and Business Administration, Vol. 3, Issue 1 · 31 Jan 2011 · 9,481 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvidence-Based Study on Performance Evaluation of Social Education Institutions with Balanced ScorecardSen-Kuei Liao, Su Fen ChenProblem statement: Based on the concept of Balanced Scorecard (BSC), this study was intended to assist the establishment of performance evaluation system for social education institutions in transforming phase. Approach: An evidence-based analysis was processed to examine the objectivity of the indicators and the weights of key factors of the current performance evaluation. Results: Based on the concept of BSC, … …Journal of Social Sciences, Vol. 6, Issue 3 · 30 Sep 2010 · 7,812 accessesView PDFCite
Research ArticleOpen accessIn the abstractPlasma Bilirubinaemia; A Physiologic Index for Monitoring Cellular Effects of Amalar, Chloroquine, Cotecxin and FansidarE. O. Jimmy, I. F. UsohProblem statement: Antimalaria drugs are highly consumed in Africa due to increase prevalent of malaria attacks. Though the disease is often cured with some antimalarials the physiologic effects of such drugs may not be considered in pharmacologic preparations and in prescriptions. Such non consideration is likely to result in serious health problems which may outweigh the effects of malaria disease … …American Journal of Pharmacology and Toxicology, Vol. 4, Issue 3 · 30 Sep 2009 · 7,541 accessesView PDFCite
Research ArticleOpen accessIn the abstractSensitivity Analysis of an Optimal Access Road Location in HillyForest Area: A GIS ApproachMohd I. Hasmadi, J.C. TaylorThere are various models for establishing the efficient forest road allocation and evaluating optimum density of forest roads network for the transport of timber commodity. Most of them are based on the calculation of common timber transport costs and costs for forest roads. Today, forest road design from traditional method continues to be transformed by remote sensing technology and advancement … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 7,609 accessesView PDFCite
Research ArticleOpen accessIn the abstractData-Driven Forecasting Schemes: Evaluation and ApplicationsJosip Vrbanek Jr, Wilson WangA reliable multi-step predictor is very useful to a wide array of applications to forecast the behavior of dynamic systems. The objective of this paper is to develop a more robust data-driven predictor for time series forecasting. Based on simulation analysis, it is found that multi-step-ahead forecasting schemes based on step inputs perform better than those based on sequential inputs. … …Journal of Computer Science, Vol. 3, Issue 9 · 30 Sep 2007 · 6,565 accessesView PDFCite
Research ArticleOpen accessIn the abstractNeural Networks for Interferences Suppression in DS/CDMA with Rayleigh Fading Channel and Power Control ErrorY. Jabrane, R. Iqdour, B. Ait Essaid et al.The exponential chip weighting waveforms have been designed with the purpose of multiple access interferences (MAI) rejection based on the concept that the optimum despreading sequence in reference emphasizes the transitions in the received spreading signal of interest. The despreading sequence weighted by exponential chip waveforms was determined by only one parameter. The objective of this study, was to introduce … …Journal of Computer Science, Vol. 3, Issue 3 · 31 Mar 2007 · 6,382 accessesView PDFCite
Research ArticleOpen accessIn the abstractLQ-Moments: Application to the Log-Normal distributionAni Shabri, Abdul A. JemainMudolkar and Hutson (1998) extended L-moments to new moment like entitles called LQmoments (LQMOM). The LQMOM are constructed by using functional defining the quick estimators, where the parameters of quick estimator take the values p = 0, α = 1 for the median, p = 1/4, α = 1/4 for the trimean and p = 0.3, α = 1/3 for … …Journal of Mathematics and Statistics, Vol. 2, Issue 3 · 30 Sep 2006 · 6,998 accessesView PDFCite
