Research ArticleOpen accessIn the keywordsAn Automatic Collocation Extraction from Arabic CorpusAbdulgabbar Mohammad Saif, Mohd J.A. AzizProblem statement: The identification of collocations is very important part in natural language processing applications that require some degree of semantic interpretation such as, machine translation, information retrieval and text summarization. Because of the complexities of Arabic, the collocations undergo some variations such as, morphological, graphical, syntactic variation that constitutes the difficulties of identifying the collocation. Approach: We used the … …Journal of Computer Science, Vol. 7, Issue 1 · 16 Dec 2010 · 8,281 accessesView PDFCite
Research ArticleOpen accessIn the keywordsIntroduction to the Besov Spaces and Triebel-Lizorkin Spaces for Hermite and Laguerre expansions and some applicationsA. Iris, P. LopezWe introduced new definitions of Besov spaces and Triebel-Lizorkin spaces associated with multidimensional Hermite expansions and multidimensional Laguerre expansions. We showed that the set of p-integrable functions is a Triebel-Lizorkin space with respect to the Gaussian measure and similarly, with respect to the probabilistic Gamma measure. Also, we showed that the Gaussian Sobolev spaces and Laguerre Sobolev spaces are Triebel-Lizorkin … …Journal of Mathematics and Statistics, Vol. 1, Issue 3 · 30 Sep 2005 · 7,580 accessesView PDFCite
Research ArticleOpen accessIn the keywordsCOMPARATIVE STUDY OF K-MEANS AND K-MEANS++ CLUSTERING ALGORITHMS ON CRIME DOMAINBashar Aubaidan, Masnizah Mohd, Mohammed AlbaredThis study presents the results of an experimental study of two document clustering techniques which are k-means and k-means++. In particular, we compare the two main approaches in crime document clustering. The drawback of k-means is that the user needs to define the centroid point. This becomes more critical when dealing with document clustering because each center point represented by … …Journal of Computer Science, Vol. 10, Issue 7 · 19 Feb 2014 · 7,762 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAUTOMATIC TEXT EXTRACTION FROM COMPLEX COLORED IMAGES USING GAMMA CORRECTION METHODG. Gayathri Devi, C. P. SumathiThe aim of this study is to propose a new methodology for text region extraction and non text region removal from complex background colored images. This study presents a new approach based on Gamma correction by determining a gamma value for enhancing the foreground details in an image. The approach also uses gray level co-occurrence matrices, texture measures, threshold concepts. … …Journal of Computer Science, Vol. 10, Issue 4 · 24 Dec 2013 · 6,679 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSHAPE RETRIEVAL THROUGH MAHALANOBIS DISTANCE WITH SHORTEST AUGMENTING PATH ALGORITHMS. Muruganathan, N. Devarajan, D. Chitra, T. ManigandanShape matching and object recognition plays an vital role in the computer vision. The shape matching is difficult in case of the real world images like mpeg database images since the real world images has the internal and external contours. The Mahalanobis distance based shape context approach is proposed to measure similarity between shapes and exploit it for shape retrieval. … …Journal of Computer Science, Vol. 10, Issue 4 · 3 Dec 2013 · 6,856 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAccreditation of Emergency Department at a Teaching Hospital in Tehran University of Medical Sciences in 2010Fereshteh Farzianpour, Roholah Askari, Amin Torabipoor Hamedani et al.Problem statement: Considering the importance of emergency departments in healthcare system and the high mortality rate of patients referred to these departments, it is crucial to provide quality services in emergency departments. Accreditation is a systematic process for improving quality of care and it enables managers to assess and evaluate the healthcare system. Accreditation of an organization provides an obvious … …American Journal of Economics and Business Administration, Vol. 3, Issue 3 · 20 Sep 2011 · 8,278 accessesView PDFCite
Research ArticleOpen accessIn the keywordsComparative Study of Antibacterial Susceptibility Patterns of the Bacteria Isolated from Patients' Blood Samples over Two PeriodsAziz Japoni, Mehdi Kalani, Abdolvahab Alborzi et al.Problem statement: Due to continuous changes in the frequencies and antibacterial susceptibility patterns of nosocomial pathogens, periodical surveillance of these fluctuations could help the clinicians to treat hospitalized patients more efficiently whenever empirical therapies need to be considered. This study was conducted to compare the prevalence of the bacteria recovered from bloodstream samples by Bactec 9240, over the two periods … …American Journal of Infectious Diseases, Vol. 7, Issue 1 · 27 Apr 2011 · 8,158 accessesView PDFCite
Research ArticleOpen accessIn the keywordsContext Disambiguation Based Semantic Web Search for Effective Information RetrievalM. Barathi, S. ValliProblem statement: Search queries are short and ambiguous and are insufficient for specifying precise user needs. To overcome this problem, some search engines suggest terms that are semantically related to the submitted queries, so that users can choose from the suggestions based on their information needs. Approach: In this study, we introduce an effective approach that captures the user’s specific … …Journal of Computer Science, Vol. 7, Issue 4 · 4 Apr 2011 · 6,879 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAnalysis of a Two Unit Standby Oil Delivering System with a Provision of Switching Over to another System at Need to Increase the AvailabilityUpasana Sharma, Rekha, Gulshan TanejaProblem statement: The study deals with a standby system consisting of two units. Initially one unit is operative and the other is standby. When both the units are failed then there is a provision of switching over to the other similar system. This practical situation may be observed in an oil refinery plant. Real data on failure and repair rates … …Journal of Mathematics and Statistics, Vol. 7, Issue 1 · 31 Jan 2011 · 7,107 accessesView PDFCite
Research ArticleOpen accessIn the keywordsOn Calculating the Hougaard Measure of Skewness in a Nonlinear Regression Model with Two ParametersS. A. EL-ShehawyProblem statement: This study presented an alternative computational algorithm for determining the values of the Hougaard measure of skewness as a nonlinearity measure in a Nonlinear Regression model (NLR-model) with two parameters. Approach: These values indicated a degree of a nonlinear behavior in the estimator of the parameter in a NLR-model. Results: We applied the suggested algorithm on an example … …Journal of Mathematics and Statistics, Vol. 5, Issue 4 · 31 Dec 2009 · 7,159 accessesView PDFCite
