Research ArticleOpen accessIn the abstractAn Efficient Bayesian Nearest Neighbor Search Using Marginal Object Weight Ranking Scheme in Spatial DatabasesK. Balasaravanan, K. DuraiswamyProblem statement: A database that is optimized to store and query data that is related to objects in space, including points, lines and polygons is called spatial database. Identifying nearest neighbor object search is a vital part of spatial database. Many nearest neighbor search techniques such as Authenticated Multi-step NN (AMNN), Superseding Nearest Neighbor (SNN) search, Bayesian Nearest Neighbor (BNN) … …Journal of Computer Science, Vol. 8, Issue 8 · 30 Jul 2012 · 7,155 accessesView PDFCite
Research ArticleOpen accessIn the abstractEmpirical Performance Metrics Study of Execution of Database Queries in Implementation of Web ServicesK. Velmurugan, M. A. Maluk MohamedProblem statement: Web services are increasingly being deployed in business applications, due to its unique features such as flexibility, interoperability and other features. Most of the business applications involve extensive use of database operations for data management in back end. Further business applications demand very high level of performance from software solutions and it is a continual and never-ending process. … …Journal of Computer Science, Vol. 8, Issue 8 · 30 Jul 2012 · 6,740 accessesView PDFCite
Research ArticleOpen accessIn the abstractContent Based Medical Image Retrieval with Texture Content Using Gray Level Co-occurrence Matrix and K-Means Clustering AlgorithmsB. Ramamurthy, K. R. ChandranProblem statement: Recently, there has been a huge progress in collection of varied image databases in the form of digital. Most of the users found it difficult to search and retrieve required images in large collections. In order to provide an effective and efficient search engine tool, the system has been implemented. In image retrieval system, there is no methodologies … …Journal of Computer Science, Vol. 8, Issue 7 · 24 May 2012 · 7,452 accessesView PDFCite
Research ArticleOpen accessIn the abstractContent Based Image Retrieval of Ultrasound Liver Diseases Based on Hybrid ApproachR. Suganya, S. RajaramProblem statement: In the past few years, immense improvement was obtained in the field of Content-Based Image Retrieval (CBIR). Nevertheless, existing systems still fail when applied to medical image databases. Simple feature-extraction algorithms that operate on the entire image for characterization of color, texture, or shape cannot be related to the descriptive semantics of medical knowledge that is extracted from … …American Journal of Applied Sciences, Vol. 9, Issue 6 · 24 Mar 2012 · 7,648 accessesView PDFCite
Research ArticleOpen accessIn the abstractVideo Retrieval using Histogram and Sift Combined with Graph-based Image SegmentationTran Quang Anh, Pham Bao, Tran Thuong Khanh et al.Problem statement: Content-Based Video Retrieval (CBVR) is still an open hard problem because of the semantic gap between low-level features and high-level features, largeness of database, keyframe’s content, choosing feature.In this study we introduce a new approach for this problem based on Scale-Invariant Feature Transform (SIFT) feature, a new metric and an object retrieval method. Conclusion/Recommendations: Our algorithm is built … …Journal of Computer Science, Vol. 8, Issue 6 · 15 Mar 2012 · 7,020 accessesView PDFCite
Research ArticleOpen accessIn the abstractSupport Vector Machine Based Red Palm Weevil (Rynchophorus Ferrugineous, Olivier) Recognition SystemGhulam Mubashar Hassan, Saleh Mufleh Al-SaqerProblem statement: Red palm weevil (Rynchophorus Ferrugineous, Oliveir) is an insect which threatens the existence of palm trees. The proposed research is to develop a RPW identification system using Support Vector Machine method. The problem is to extract image features from an image and using SVM to find out the existence of RPW in an image. Approach: Images are snapped … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 1 · 24 Jan 2012 · 7,737 accessesView PDFCite
Research ArticleOpen accessIn the abstractRetrieval Optimization Technique for Tuple Timestamp Historical Relation Temporal Data ModelSami M. Halawani, Ibrahim AlBidewi, Ab Rahman Ahmad, Nashwan A. Al-RomemaProblem statement: In the field of database technology, Recoding time related data are referred to as temporal databases. Conventional relational databases are queried using the underlying constructs of SQL which are translated into Relational Algebra (RA). Relational Algebra (RA) is the writing of logical expressions that uses a set of relational operators to perform operations on specific relation(s) and returns … …Journal of Computer Science, Vol. 8, Issue 2 · 9 Dec 2011 · 7,378 accessesView PDFCite
Research ArticleOpen accessIn the abstractFirst Token Algorithm for Searching Compound Terms Using Thesaurus DatabaseYousef Abuzir, Thabit SabbahProblem statement: Searching text materials is the one of the most important operations that carried out by search engines either on web or desktop applications, searching algorithms are required sometimes to find a specific word into a text, others to find a multi word term (pattern matching) into a text. Searching for term into a thesaurus database can be carried … …Journal of Computer Science, Vol. 8, Issue 1 · 28 Oct 2011 · 7,950 accessesView PDFCite
Research ArticleOpen accessIn the abstractSmart Card Identification Management Over A Distributed Database ModelOlatubosun OlabodeProblem statement: An effective national identification system is a necessity in any national government for the proper implementation and execution of its governmental policies and duties. Approach: Such data can be held in a database relation in a distributed database environment. Till date, The Nigerian government is yet to have an effective and efficient National Identification Management System despite the … …Journal of Computer Science, Vol. 7, Issue 12 · 15 Oct 2011 · 6,868 accessesView PDFCite
Research ArticleOpen accessIn the abstractFrontal Arabic Fricative Consonants Characteristics among Primary School Children: Spectral Density Function ApproachNurul Ashikin Abdul-Kadir, Rubita SudirmanProblem statement: Arabic speech recognition system is un-developed until today. By using people of non-Arab nationality, the set of frontal fricative of Arabic consonants are study as the earlier step to develop the recognition system for Malaysian. As most of the developed Arabic speech recognition system for Malaysian are rarely found. Approach: The characteristic of each of the phonemes were … …Journal of Computer Science, Vol. 7, Issue 10 · 9 Aug 2011 · 7,178 accessesView PDFCite
