Research ArticleOpen accessIn the abstractA Layout Based Detachment Approach for Extracting Content from WebpagesDeepa Chandran, Anna Saro VijendranEnormous amount of useful information presented in Internet is usually formatted for the web users. But it is a really complex task to extract the relevant data from various web sources. Recently, various approaches for the extraction of data from the webpages were proposed. This study provides a simple but effective approach, named Layout Based Detachment Approach (LBDA). The proposed … …American Journal of Applied Sciences, Vol. 12, Issue 6 · 25 Jul 2015 · 6,345 accessesView PDFCite
EditorialOpen accessIn the abstractData Mining in Time Series: Current Study and Future TrendTan Yan, Liudmila Ulanova, Ye Ouyang, Fengyuan XuTime series represent sequences of data points where usually their order is defined by the time when they were recorded. Thus, virtually any sequential recordings can be stored as time series: Stock prices, weather conditions, physical system parameters change, product quality monitoring, etc. This leads to ubiquity of time series in all scientific and practical fields (Esling and Agon, 2012); … …Journal of Computer Science, Vol. 10, Issue 12 · 26 Jan 2015 · 8,756 accessesView PDFCite
Research ArticleOpen accessIn the abstractA COMBINTORIAL TREE BASED FREQUENT PATTERN MININGN. Yamuna Devi, J. Devi ShreeFrequent pattern mining is a process of extracting frequently occurring itemset patterns from very large data storages. These frequent patterns are used to generate association rules which define the relationship among items. The strength of the relationship can be measured using two different units namely support value and confidence level. Any relationship that satisfies minimum threshold of support value is … …Journal of Computer Science, Vol. 10, Issue 9 · 23 Jun 2014 · 6,804 accessesView PDFCite
Research ArticleOpen accessIn the abstractEFFECTIVE HEURISTIC ALGORITHM FOR DYNAMIC ROUTING AND BANDWIDTH MANAGEMENT UNDER QUALITY OF SERVICE CONSTRAINTS IN MULTISTAGE INTERCONNECTION NETWORKSR. Deepalakshmi, S. RajaramToday, Internet of Things (IoT) has introduced abundant bandwidth consumption and necessities in multimedia communications from online games to video-conferencing applications with the constraint of QoS requirements from time to time. The expected rapid proliferation of services would require performance unprecedented in the currently available best-effort routing algorithms. In, particular, the present routing mechanisms are based on the best-effort paradigm … …American Journal of Applied Sciences, Vol. 11, Issue 3 · 7 Jan 2014 · 7,138 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Efficient Algorithm for Mining Spatially Co-located Moving ObjectsG. Manikandan, S. SrinivasanMining co-location patterns from spatial databases may disclose the types of spatial features which are likely located as neighbors’ in space. Accordingly, we present an algorithm previously for mining spatially co-located moving objects using spatial data mining techniques and Prim’s Algorithm. In the previous technique, the scanning of database to mine the spatial co-location patterns took much computational cost. In … …American Journal of Applied Sciences, Vol. 10, Issue 3 · 2 Mar 2013 · 6,649 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign of Tree Structure in Context Clustering Process of Hidden Markov Model-Based Thai Speech SynthesisSuphattharachai ChomphanProblem statement: In HMM-based Thai speech synthesis, the tone degradation due to the imbalance of training data of all tones. Some distortion of syllable duration is obviously noticeable when the system is trained with a small amount of data. These problems cause the decrement in naturalness and intelligibility of the synthesized speech. Approach: This study proposes an approach to improve … …American Journal of Applied Sciences, Vol. 9, Issue 3 · 14 Jan 2012 · 6,955 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimulation of Vegetative Induced Deformation in an Unsaturated SoilNazri Bn Ali, Mu’azu Mohammed AbdullahiProblem statement: Tree root water-uptake increases soil strength by increasing the soil matric suction due to pore pressure dissipation in a soil mass, inducing increases in vertical total stress or water extraction, the effective stress to which the soil strata is subjected to may also increase. This causes volume change which might be detrimental to geotechnical structures and shallow foundation. … …American Journal of Environmental Sciences, Vol. 6, Issue 2 · 30 Apr 2010 · 7,135 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of Deduced Protein Database Using Variable Bit Binary EncodingB. Parvathavarthini, B. Rajesh Kanna, L. RajeswarideviA large amount of biological data is semi-structured and stored in any one the following file formats such as flat, XML and relational files. These databases must be integrated with the structured data available in relational or object-oriented databases. The sequence matching process is difficult in such file format, because string comparison takes more computation cost and time. To reduce … …Journal of Computer Science, Vol. 4, Issue 6 · 30 Jun 2008 · 6,512 accessesView PDFCite
Research ArticleOpen accessIn the abstractEfficient Physical Organization of R-Trees Using Node ClusteringF. Sagayaraj Francis, P. ThambiduraiR-Tree is a multidimensional indexing structure that forms basis for all the multidimensional indexing structures based on data partitioning. A number of attempts have been made in the past to improve the performance of R-Tree by manipulating the tree parameters and the data parameters. But hardly any attempt had been made to use external parameters such as disk parameters to … …Journal of Computer Science, Vol. 3, Issue 7 · 31 Jul 2007 · 6,627 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Importance of Maintaining a Proper Database on Forest Restoration Program for Orangutans in BorneoRaymond Alfred, Koh Pei Hue, Lee Shan Khee, Rayner AlfredProblem statement: The lowland forest of Sabah is the most important habitat for orangutans and pygmy elephants. This is shown in the WWF-Malaysia’s elephant tracking programme in which satellite-based Global Position System (GPS) collar devices are used to monitor their movement and the range of their habitats, as well as an aerial survey on orangutan’s nest is performed to determine … …American Journal of Environmental Sciences, Vol. 6, Issue 2 · 30 Apr 2010 · 7,910 accessesView PDFCite
