Research ArticleOpen accessIn the abstractFragment-based Visual Tracking with Multiple RepresentationsJunqiu Wang, Yasushi YagiWe present a fragment-based tracking algorithm that considers appearance information characterized by a non-parametric distribution and spatial information described by a parametric representation. We segment an input object into several fragments based on the appearance similarity and spatial distribution. Spatial distribution and appearance are important for distinguishing different fragments. We employee such information for separating an object from its background: … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 2 · 5 Jan 2016 · 7,894 accessesView PDFCite
Research ArticleOpen accessIn the abstractLocal Climate Trends and Farmers’ Perceptions in Southern Tigray, Northern EthiopiaM. G. Abrha, S. SimhadriThis study aimed to investigate changes in local climate, farmers’ perception to the change and factors affecting perception of farmers to climate change. For trend analysis, we gathered station based rainfall records for the period 1978-2012, while for perception analysis survey was carried out. 600 farming households were randomly selected from four districts using a multi-stage sampling method. Nonparametric analysis … …American Journal of Environmental Sciences, Vol. 11, Issue 4 · 8 Oct 2015 · 7,926 accessesView PDFCite
Research ArticleOpen accessIn the abstractA MATHEMATICAL ANALYSIS OF THE INCLUSION OF INSTITUTIONAL BETTING FUNDS INTO STOCK MARKET: THE CASE OF TECHNICAL AND FUNDAMENTAL PAYOFF MODELS IN HORSERACE BETTINGCraig George Leslie Hopf, Gurudeo Anand TularamHorserace win and place returns have yet to be considered seriously as portfolio inputs in financial trading markets. However there exist technical and fundamental stochastic models of parametric and nonparametric distribution that appear to optimize expected returns from win and place investing in the horserace wagering market. In this study, a complex number optimization technique is introduced and applied to … …Journal of Mathematics and Statistics, Vol. 10, Issue 3 · 23 Aug 2014 · 6,794 accessesView PDFCite
Research ArticleOpen accessIn the abstractSUPER RESOLUTION FOR EGYPTSAT-1 IMAGES WITH ERRATIC SHIFTA. H. Nasr, Gh.S. El-Tawel, A. K. HelmyThe key point of the Super-Resolution (SR) process is the accurate registration of the low resolution images, i.e., accurate measuring of the fixed shift between them, to obtain high resolution image. Due to certain malfunction, some Egyptsat-1 images have inconsistent sub-pixel shift. Therefore, in this study we propose a methodology to use this kind of shift for reconstructing a SR … …Journal of Computer Science, Vol. 10, Issue 7 · 17 Jun 2014 · 6,945 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Bisphenol a on Passive Avoidance Performance in Male RatsMahnaz Taherianfard, Bita Geramizadeh, Mehrzad Banihashemi et al.Bisphenol A (BPA) is used to manufacture polycarbonate plastic products in resins lining metal cans, in dental sealants and in blends with other types of plastic products. In sharp contrast, there are many published studies that BPA has a wide range of significant adverse effects including structural and neurochemical changes throughout the brain associated with behavioral changes, such as hyperactivity, … …Current Research in Medicine, Vol. 4, Issue 2 · 10 Dec 2013 · 7,225 accessesView PDFCite
Research ArticleOpen accessIn the abstractTREND ANALYSIS OF MONTHLY RAINFALL DATA IN CENTRAL ZONETelemu KassileProper trend analysis of rainfall data is necessary for social and economic planning especially in the tropics where rainfall is a major limiting factor for crop production. In spite of the growing number of studies on climatic variables including rainfall in recent years, in the context of Tanzania little is known as to whether or not the observed time trend … …Journal of Mathematics and Statistics, Vol. 9, Issue 1 · 15 Mar 2013 · 7,945 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesigning of Child Growth Chart Based on Multi-Response Local Polynomial ModelingNur Chamidah, I. Nyoman Budiantara, Sony Sunaryo, Ismaini ZainProblem statements: Anthropometry measures used to measure physical children growth are not onlyweight but also height and head circumference. In this study we develop the estimation of multi-response localpolynomial regression and apply it to design growth chart for children up to five years old based on three responsevariables i.e., weight, height and head circumference. Approach: Based on local polynomial estimator, … …Journal of Mathematics and Statistics, Vol. 8, Issue 3 · 4 Sep 2012 · 7,510 accessesView PDFCite
Research ArticleOpen accessIn the abstractUsing Multi-Scale Filtering to Initialize a Background Extraction ModelS. H. Davarpanah, Fatimah Khalid, N. A. Lili et al.Problem statement: Probability-based methods which usually work based on the saved history of each pixel are utilized severally in extracting a background image for moving detection systems. Probability-based methods suffer from a lack of information when the system first begins to work. The model should be initialized using an alternative accurate method. Approach: The use of a nonparametric filtering to … …Journal of Computer Science, Vol. 8, Issue 7 · 24 May 2012 · 7,279 accessesView PDFCite
Research ArticleOpen accessIn the abstractHeart Rate Variability Analysis in Different Age and Pathological ConditionsM.E.S. Chelladurai, N. KumaravelProblem statement: Heart Rate Variability (HRV) has been used as a measure of mortality primarily with patients who had undergone cardiac surgery. The analysis of Heart Rate Variability (HRV) demands specific capabilities which are not provided either by parametric or nonparametric conventional estimation methods. The Empirical Mode Decomposition (EMD) adaptively estimates the Intrinsic Mode Functions (IMFs) of nonlinear nonstationary signals. … …Journal of Computer Science, Vol. 7, Issue 10 · 4 Aug 2011 · 6,822 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Intraarticular Tramadol Administration on Biochemical and Cytological Properties of Equine Synovial Fluid: Comparison with LidocaineAlireza Raayat Jahromi, Abutorab Tabatabaei Naeini, Saeed NazifiProblem statement: Diagnostic and therapeutic arthroscopic surgeries are procedures performed quite frequently in equine practice; and are considered to cause some degree of postoperative pain. The aim of the present study was to evaluate the equine synovial fluid biochemical and cytological changes following intra-articular administration of tramadol as a potential analgesic. Approach: Six adult healthy donkeys were selected after clinical … …American Journal of Pharmacology and Toxicology, Vol. 6, Issue 1 · 14 Jun 2011 · 7,519 accessesView PDFCite
