Research ArticleOpen accessIn the abstractIMMUNOHISTOCHEMICAL ANALYSIS OF UROTHELIAL BLADDER CANCERSKatarina Bevizova, Jan Jakubovsky, Jan Luha et al.Malignant cancers of urinary bladder are the second most common malignancy of the urinary tract and the fourth most common malignancy in general, especially in men. The aim of this study was a retrospective analysis of selected markers (p53, Ki-67 and E-cadherin) of urinary bladder cancers from the Department of Urology in Bratislava, Slovak Republic between years 2007 and 2009. … …OnLine Journal of Biological Sciences, Vol. 13, Issue 2 · 17 Jul 2013 · 7,372 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 · 7,939 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign, Development and Numerical Analysis of Honeycomb Core with Variable Crushing StrengthShabnam Sadeghi Esfahlani, Hassan Shirvani, Ayoub Shirvani et al.A honeycomb core with half-circular cut-away sections at the spine (the adjoining cell walls) is designed and developed and numerically tested under axial dynamic load condition. The parametric study is invoked to identify the effect of various circular cut-away dimensions. In one embodiment a half-circular shaped cuts are removed from the top of the cell where the cell is impacted … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 1 · 15 Jan 2013 · 7,572 accessesView PDFCite
Research ArticleOpen accessIn the abstractMeasures of Explained Variation and the Base-Rate Problem for Logistic RegressionDinesh Sharma, Dan McGee, B.M. Golam KibriaProblem statement: Logistic regression, perhaps the most frequently used regression model after the General Linear Model (GLM), is extensively used in the field of medical science to analyze prognostic factors in studies of dichotomous outcomes. Unlike the GLM, many different proposals have been made to measure the explained variation in logistic regression analysis. One of the limitations of these measures … …Current Research in Biostatistics, Vol. 2, Issue 1 · 25 Feb 2012 · 8,576 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Efficiency Measurement of Parallel Production Systems: A Non-radial Data Envelopment Analysis ModelAli Ashrafi, Azmi Bin Jaafar, Mohd Rizam Abu Bakar, Lai Soon LeeProblem statement: Data Envelopment Analysis (DEA) is a non-parametric technique for measuring the relative efficiency of a set of production systems or Decision Making Units (DMU) that have multiple inputs and outputs. Sometimes, DMUs have a parallel structure, in which systems composed of parallel units work individually; the sum of their own inputs/outputs is the input/output of the system. For … …Journal of Computer Science, Vol. 7, Issue 5 · 7 May 2011 · 9,253 accessesView PDFCite
Research ArticleOpen accessIn the abstractElastic-Plastic Non Linear Behaviors of Suddenly Loaded StructuresAssal Tehseen HusseinProblem statement: The adaptively shifted integration technique was applied to the elasticplastic analysis of framed structures under dynamic loading. Approach: This study used analysis of linear beam element, the reshifting of the of the integration points in the element is conducted in order to attain higher accuracy. Results: In nonlinear finite element analysis by the ASI technique, the highest computational … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 31 Jan 2011 · 8,004 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of Evapotranspiration Variability and Trends in the Arabian PeninsulaMohammad ElNesr, Abdulrahman Alazba, Majed Abu-ZreigProblem statement: Climate variability is receiving much attention recently because it has significant effects on water resources and therefore on the livelihood of society especially in water scarce countries such the Kingdom of Saudi Arabia (KSA). Approach: The aim of this study was to explore changes in the reference evapotranspiration (ETo) using data from 27 weather stations through years 1980-2008 … …American Journal of Environmental Sciences, Vol. 6, Issue 6 · 31 Dec 2010 · 8,005 accessesView PDFCite
Research ArticleOpen accessIn the abstractFinite Element Analysis of Composite Hardened Walls Subjected to Blast LoadsGirum S. UrgessaProblem statement: There is currently no standard design guideline to determine the number of composites needed to retrofit masonry walls in order to withstand a given explosion. Past design approaches were mainly based on simplified single-degree-of-freedom analysis. A finite element analysis was conducted for concrete masonry walls hardened with composites and subjected to short duration blast loads. Approach: The analysis … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 7,266 accessesView PDFCite
Research ArticleOpen accessIn the abstractComputer Aided Geometric Modeling of Twist FiberKeartisak Sriprateep, Adisak PattiyaProblem statement: The objective of this study is to compare the methods for approximating the positions of twist fiber in yarn structures. Computer Aided Design (CAD) is applied using parametric equation, spline curve and NURBS curve. The ideal twist fiber and fiber migration are studied in 3 dimensions. Approach: The fiber positions in yarn structures were measured by trace fiber … …Journal of Computer Science, Vol. 5, Issue 3 · 31 Mar 2009 · 7,342 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Total Productivity PCA Model for Assessment and Improvement of Electrical Manufacturing SystemsAli Azadeh, Farid GhaderiThis study presents a framework for assessment of electrical manufacturing systems based on a total machine productivity approach and multivariate analysis. Furthermore, the total model is developed by Principle Component Analysis (PCA) and validated and verified by Numerical Taxonomy (NT) and non-parametric correlation methods, namely, Spearman correlation experiment and Kendall Tau. To achieve the objectives of this study, a comprehensive … …Journal of Mathematics and Statistics, Vol. 1, Issue 3 · 30 Sep 2005 · 6,270 accessesView PDFCite
