Research ArticleOpen accessIn the abstractComparison of Stochastic and Deterministic Methods for Mapping Environmental Noise from Opencast QuarriesDario Lippiello, Guido Alfaro Degan, Mario PinzariAn accurate mapping of the acoustic spatial variability generated by quarrying plants constitutes an important step in the assessment of the environmental compatibility of the extraction site with the surrounding area. This paper refers to the results of a study comparing performances obtained by stochastic and deterministic methods to determine the acoustic climate of the areas surrounding opencast quarries. To … …American Journal of Environmental Sciences, Vol. 12, Issue 2 · 28 Mar 2016 · 7,394 accessesView PDFCite
Research ArticleOpen accessIn the abstractGENDER PREFERENCES FOR ALTERNATIVE ENERGY TRANSPORT WITH FOCUS ON ELECTRIC VEHICLENirupama Prakash, Rashmi Kapoor, Ajay Kapoor, Yashpal MalikTransportation has become an important part of our day to day life. Due to changing lifestyle, frequent travels whether related to work or leisure has become a common phenomenon. Such lifestyle also demands comfortable transport medium and reasonable availability of fuels. As need of vehicle for transportation is rising, it has put pressure of fuel supply, fuel prices and environment … …Journal of Social Sciences, Vol. 10, Issue 3 · 13 Oct 2014 · 8,643 accessesView PDFCite
Research ArticleOpen accessIn the abstractA NOVEL ROBUST AND EFFICIENT TOOL FOR DETECTING HETEROSCEDASTICITYWei Xiong, Maozai TianOne of the greatest values of Quantile Regression (QR) is that it provides a good procedure in the sense that QR could be much more efficient and sometimes arbitrarily more efficient in recovering the mean function than the Least Squares (LS) even when without moment conditions. However, heteroscedasticity definitely causes conditional variances of parametric or nonparametric estimates of mean functions … …Journal of Mathematics and Statistics, Vol. 10, Issue 2 · 21 Mar 2014 · 6,657 accessesView PDFCite
Research ArticleOpen accessIn the abstractDoes Over or Under Dispersion in Inverse Binomial Data Suggest Anything? A Case in Point is the Waiting Time for Both Heart-Lung TransplantsRamalingam ShanmugamThe model is an abstraction of the reality. The selection of the usual inverse binomial as an underlying model for the number of patients waiting in months for heart and lung transplant is questionable because the data exhibit not the required balance between the dispersion and its functional equivalent in terms of the mean but rather an over or under … …Current Research in Biostatistics, Vol. 3, Issue 2 · 29 Jan 2014 · 6,888 accessesView PDFCite
Research ArticleOpen accessIn the abstractMosaic Masonries to Interpret Diagnostic Test ResultsRamalingam ShanmugamCurrently, assessing superiority of a diagnostic test requires cumbersome calculations and confusing interpretations because of nonlinear Receiver Operating Characteristic Curve (ROC). To remedy these difficulties, this article prepares, provides an easier alternate geometric approach. That is, a simple but more effective visual approach with two complementary mosaic masonries are constructed with their properties, superimposed and utilized. First masonry is conditional … …Current Research in Medicine, Vol. 4, Issue 1 · 12 Feb 2013 · 6,854 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Evaluation of Adaptive Filter and Neuro-Fuzzy Filter in Artifacts Removal From Electroencephalogram SignalPaulchamy Balaiah, IlavennilaProblem statement: This study presents an effective method for removing mixed artifacts (EOG-Electro-ocular gram, ECG-Electrocardiogram, EMG-Electromyogram) from the EEG-Electroencephalogram records. The noise sources increases the difficulty in analyzing the EEG and obtaining clinical information. EEG signals are multidimensional, non-stationary (i.e., statistical properties are not invariant in time), time domain biological signals, which are not reproducible. It is supposed to contain … …American Journal of Applied Sciences, Vol. 9, Issue 10 · 15 Aug 2012 · 7,087 accessesView PDFCite
Research ArticleOpen accessIn the abstractTest Anxiety and Foreign Language Reading Anxiety in a Reading-Proficiency TestYa-Chin Tsai, Yi-Chih LiProblem statement: The impact of foreign-language anxiety has been researched with respect to the reading domain; however, how it affects reading proficiency in relation to test anxiety in a test situation is yet to be explored. Approach: This study investigated possible relationships between test anxiety, foreign language reading anxiety and English reading proficiency by using scales published in previous studies. … …Journal of Social Sciences, Vol. 8, Issue 1 · 8 Feb 2012 · 15,184 accessesView PDFCite

Purpose: Modeling the characteristics of personality and motivation of medical student's development following the establishment of an appropriate methodology to act in university physical education lessons by developing and implementing a strategic program included in organization, management and conduct training process-education, the means of … …Journal of Social Sciences, Vol. 7, Issue 4 · 10 Aug 2011 · 8,187 accessesView PDFCite
Research ArticleOpen accessIn the abstractEstimation of Non-Residential Building Energy ConsumptionYongzhi Gao, Weijun Gao, Ji Xuan, Yutaka TonookaProblem statement: China’s energy consumption is increasing with a high-speed in recent years. Especially since building energy consumption caught pubic eyes and became a crucial problem of society, it forced the public to make estimation in order to reduce energy consumption efficiently. However, it is very difficult to analyze a non-residential building accurately due to China’s statistical collection system and … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 3 · 30 Sep 2010 · 8,012 accessesView PDFCite
Research ArticleOpen accessIn the abstractLead Free Solder Joint Thermal Condition in Semiconductor PackagingM. Najib Harif, Allina Nadzri, Kamaruzaman JusoffProblem statement: Solder joints are responsible for both electrical and mechanical connections. Solder does not have adequate ductility to ensure the repeated relative displacements due to the mismatch between expansion coefficients of the chip carrier and the circuit board. Solder material plays a crucial role to provide the necessary electrical and mechanical interconnections in an electronic assembly. Finding a technique … …American Journal of Applied Sciences, Vol. 7, Issue 7 · 31 Jul 2010 · 7,160 accessesView PDFCite
