Research ArticleOpen accessIn the abstractPathophysiology of Adipocyte Defects and Dyslipidemia in HIV Lipodystrophy: New Evidence from Metabolic and Molecular StudiesAshok Balasubramanyam, Rajagopal V. Sekhar, Farook Jahoor et al.Despite a burgeoning mass of descriptive information regarding the epidemiology, clinical features, body composition changes, hormonal alterations and dyslipidemic patterns in patients with HIV lipodystrophy syndrome (HLS), the specific biochemical pathways that are dysregulated in the condition and the molecular mechanisms that lead to their dysfunction, remain relatively unexplored. In this paper, we review studies that detail the metabolic basis … …American Journal of Infectious Diseases, Vol. 2, Issue 3 · 30 Sep 2006 · 6,611 accessesView PDFCite
Research ArticleOpen accessIn the abstractDFT Based Electrophilicity Index and QSAR study of Phenols as Anti Leukaemia AgentFarhan A. Pasha, Hemant K. Srivastava, Yakoob Beg, Pashupati P. singhDensity Functional reactivity indices based QSAR study of 49 phenol derivatives is presented in this paper. Two different models to describe the anti leukaemia activity of phenols have been made. First QSAR model includes molecular properties like molecular weight (Mw), hardness (η), chemical potential (μ), total energy, and electrophilicity index (ω). Various regression models have been made and regression quality … …American Journal of Immunology, Vol. 2, Issue 1 · 31 Mar 2006 · 7,593 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn Recipe Based Service Composition in Ubiquitous Smart SpacesJunaid A. Chowdary, Seung-Kyu Park, Suk-Kyo HongWe present a recipe based service composition scheme in smart spaces. We discuss real time problems of highly synchronized and user customizable processes with the help of an example. On-the-fly Quality of Service (QoS) shows up as a major issue in such environment. Furthermore the QoS of a dynamically composed service depends upon the aggregate QoS of its developing components. … …Journal of Computer Science, Vol. 2, Issue 1 · 31 Jan 2006 · 6,766 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Design and Implementation of Parallel Digital Library Management SystemYang Yan, Li Jianzhong, Kan ZhongliangAs the number of documents in digital library grows, it becomes increasingly difficult to store, manage the large amount of documents and finding requested relevant documents by users. Parallel Digital Library management System (PDLS) is used for this purpose. PDLS is a general tool for building and managing digital libraries of all kinds of documents to meet user needs. It … …Journal of Computer Science, Vol. 1, Issue 2 · 30 Jun 2005 · 7,286 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordCharacterization of Composite Structure Surface Uniformity using Interval Based Gradient Field Histogram Analysis of Thermographic Images (IGF-HA)Mahmoud Zaki IskandaraniThis paper presents a new approach to composite surface characterization using Image Histogram Analysis as a function of Gradient Field. Image sequences are weighed and combined in order to present a pattern change in the thermal response of a tested composite structure. Reaction Injection Molding samples used and subjected to thermal energy to characterize their surface uniformity and any existing … …Journal of Computer Science, Vol. 14, Issue 6 · 25 May 2018 · 7,977 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA New Bivariate Distribution with Generalized Quadratic Hazard Rate MarginalsAbdelfattah MustafaRecently, Sarhan (2009) introduced a new distribution named generalized quadratic hazard rate distribution. In this study, we define a bivariate Generalized Quadratic Hazard Rate Distribution (BGQHRD). The joint cumulative distribution function and joint survival function are derived in compact forms. Several properties of BGQFRD have been discussed. The conditional probability density function, rth moments and joint and marginal moment generating … …Journal of Mathematics and Statistics, Vol. 12, Issue 4 · 3 Nov 2016 · 6,751 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordBaseline Concentrations of 11 Elements as a Function of Land uses in Surface Soils of the Katangese Copperbelt Area (D.R. Congo)Martin T. Mpinda, Tresor N. Kisimba, Theodore M. Mwamba et al.The Katangese Copperbelt Area (KCA) located south-eastern of D.R. Congo presents high concentration of Metal Trace Elements (MTE) due to a rich natural geochemical background and intense mining activities. However, the lack of data on specific baseline concentrations makes it difficult to assess and monitor the environmental quality of soils in the region. In this study, 11 MTE were measured … …American Journal of Environmental Sciences, Vol. 17, Issue 6 · 3 Jan 2022 · 7,128 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordPerformance Evaluation of Search Engines Using Enhanced Vector Space ModelJitendra Nath Singh, Sanjay K. DwivediVector space model allows computing a continuous degree of similarity between queries and retrieved documents and then ranks the documents in increasing order of cosine (similarity) value. It computes cosine or similarity value using their cosine function. The cosine function computes the similarity value by computing the weight of each term in the documents using a weighting scheme but it … …Journal of Computer Science, Vol. 11, Issue 4 · 24 Jul 2015 · 6,761 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordDEVELOPMENT OF OBSTACLE AVOIDANCE TECHNIQUE IN WEB-BASED GEOGRAPHIC INFORMATION SYSTEM FOR TRAFFIC MANAGEMENT USING OPEN SOURCE SOFTWARENik Mohd Ramli Nik Yusoff, Helmi Zulhaidi Mohd Shafri, Ratnasamy Muniandy, Islam Mohammad WaliThe shortest path routing is one of the well-known network analysis techniques implemented in road management systems. Pg Routing as an extension of Postgre SQL/Post GIS database is an open source library that implements the Dijkstra shortest path algorithm. However, the functionality to avoid obstacles in that analysis is still limited. Therefore, this study was conducted to enable obstacle avoidance … …Journal of Computer Science, Vol. 10, Issue 7 · 16 Jun 2014 · 6,933 accessesView PDFCite
