Research ArticleOpen accessEvery word in the titleA Comparative Analysis of the Entropy and Transition Point Approach in Representing Index Terms of Literary TextHayati Abd Rahman, Shahrul Azman NoahProblem statement: Concept hierarchy is a hierarchically organized collection of domain concepts. It is particularly useful in many applications such as information retrieval, document browsing and document classification. Approach: One of the important tasks in construction of concept hierarchy is identification of suitable terms with appropriate size of domain vocabulary. Results: One way of achieving such a size is by … …Journal of Computer Science, Vol. 7, Issue 7 · 30 Jun 2011 · 6,678 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleVoltage Oriented Control Applied to a Grid Connected Photovoltaic System with Maximum Power Point Tracking TechniqueRym Marouani, Abdelkader MamiProblem statement: This study presented a grid connected photovoltaic system with voltage oriented control. This system contains the problem of degradation of photovoltaic power with climatic factors and the problem of synchronization of currents to be injected to the grid. Approach: In order to optimize the photovoltaic energy generation, we developed a new maximum power point tracking algorithm and we … …American Journal of Applied Sciences, Vol. 7, Issue 8 · 31 Aug 2010 · 8,698 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleUtilization and Modification of Point Sampling and Line Sampling in the Forestry SurveyDifei ZhangProblem statement: In the practice of conventional point sampling and line sampling methods in the forestry survey, we often encounter problems such as boundary and hole problems. These problems could introduce bias in the results of forest sampling. Proper modifications are needed. Approach: This study developed novel probability computation approaches in the utilization and modification of horizontal point sampling and … …Current Research in Biostatistics, Vol. 1, Issue 1 · 30 Jun 2010 · 7,679 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Fixed Point Theorems in L-Fuzzy Quasi-Metric SpacesReza Saadati, S. Mansour VaezpourAt first we considered the L-fuzzy metric space notation which is useful in modeling some phenomena where it is necessary to study the relationship between two probability functions as well observed in Gregori et al. [A note on intuitionistic fuzzy metric spaces. Chaos, Solitons and Fractals 2006; 28: 902-905]. Then we introduced the concept of fixed point theorem in L-fuzzy … …American Journal of Applied Sciences, Vol. 6, Issue 2 · 28 Feb 2009 · 7,408 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEvaluation of Nitrogen Non-Point Sources in Po River Near TurinGiuseppe Genon, Franco MarcheseThe non-point hydraulic and nitrogen loads in the stretch of Po river upstream and downstream from the city of Turin have been investigated, on the basis of regular data concerning quality and flow rates in the river in different periods of a reference year. The collected data have been organized in terms of hydraulic and mass balances, taking into account … …American Journal of Environmental Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 6,644 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleComputer 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 · 6,651 accessesView PDFCite
Review ArticleOpen accessEvery word in the titleRecent Advances in Point of Care Diagnostic Tools: A ReviewLaura Wessels, Haider RaadGlobally, there is a great need for portable, inexpensive diagnostic tools that can provide quick, accurate results using relatively small sample volumes. Point-Of-Care (POC) measurements of human saliva, sweat and/or blood capable of detecting glucose levels, foreign pathogens such as bacteria, fungi and many different viruses (HIV, Ebola, Influenza, etc.) that use microfluidics and optofluidics are close to commercial availability. … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 28 Nov 2016 · 8,244 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleExploratory Analysis of Rainfall Occurrence in South Sulawesi Region Using Spatial Point ProcessNurtiti Sunusi, Erna Tri Herdiani, Fachrul Nawawi, GiarnoThis paper study the probability of rainfall occurrence in round year in different segment in South Sulawesi region. In this research, rainfall occurrence in round year described by one line which has divided into 12 months. Each one of those months is assumed that the probability of a rainfall follow a homogeneous Poisson distribution. To modeling the rainfall occurrence in … …Journal of Mathematics and Statistics, Vol. 11, Issue 4 · 15 Feb 2016 · 7,453 accessesView PDFCite
