Research ArticleOpen accessIn the abstractSurvival and Mediation Analysis with Correlated FrailtyUsha S Govindarajulu, Mohsin QadriMany studies have focused on mediation effects, but fewer have focused on these in a time-to-event analysis and even fewer have focused on these effects in a survival model with frailty effects. The purpose of this study was to show unique modeling of correlated frailty effects with mediation and to demonstrate their use through simulations as well as on a … …Current Research in Biostatistics, Vol. 9, Issue 1 · 1 Dec 2019 · 13,005 accessesView PDFCite
Research ArticleOpen accessIn the abstractWillingness to Pay for Water Hyacinth Control in NepalUmesh Khatri, Resham Bahadur Thapa-Parajuli, Uttam PaudelWater Hyacinth (WH) has become a growing problem across Asia, specifically in Nepal. Infestations of this weed have reached critical proportions in freshwater bodies, causing environmental, economic, agricultural and social problems. These problems have corresponding monetary values. This study elicits the willingness of visitors and local people to control WH in the Phewa Lake in Nepal. Considering three scenarios encircling … …American Journal of Environmental Sciences, Vol. 14, Issue 5 · 14 Nov 2018 · 8,189 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Better Approach to Ontology Integration using Clustering Through Global Similarity MeasureAshwin Makwana, Amit GanatraKnowledge representation is a crucial area of work in the intelligent system, especially in query answering system development. Ontology is used to represent shared knowledge of a particular domain for query answering system. Domain-specific ontology can be designed and developed by many groups and researchers, because of which there is heterogeneity in the knowledgebase. Ontology integration or merging is necessary … …Journal of Computer Science, Vol. 14, Issue 6 · 25 Jun 2018 · 8,227 accessesView PDFCite
Review ArticleOpen accessIn the abstractReview on Apiary Management and Antimicrobial Compounds as Alternative Prevention or Treatment for Honeybee DiseasesChanpen Chanchao, Marko Stoić, Mikio Yoshiyama, Kiyoshi KimuraHoneybees are important in terms of pollinators and bee products. However, honeybee colonies keep declining due to colony collapse disorder, loss of food sources, environmental deterioration, pesticide exposure and various diseases, as well as the interaction of these causes. Pathogenic infections are high because there is an antagonistic coevolution between host and pathogen/parasite, which leads to a reciprocal adaptation, as … …OnLine Journal of Biological Sciences, Vol. 18, Issue 1 · 15 Jan 2018 · 7,738 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Hybrid Method for Network Anomaly Detection Based on Traffic Prediction and Change Point DetectionMouhammd AlkasassbehIn recent years, computer networks have become more and more advanced in terms of size, applications, complexity and level of heterogeneity. Moreover, availability and performance are important issues for end users. New types of cyber-attacks that can affect and damage network performance and availability are constantly emerging and some threats, such as Distributed Denial of Service (DDoS) attacks, can be … …Journal of Computer Science, Vol. 14, Issue 2 · 3 Jan 2018 · 8,404 accessesView PDFCite
Research ArticleOpen accessIn the abstractENHANCED LOAD BALANCING STRATEGY IN HETEROGENEOUS PEER-TO-PEER NETWORKSP. Murugesan, A. ShanmugamExisting P2P systems provide a Duty Cycle Data Appropriation (DCDA) Technique allocate objects based on ranking among “peer nodes” in a method that result in various nodes containing times as numerous objects as the standard node. Further disparity might effect owing to non-uniform allocation of objects in the identifier break and a high amount of heterogeneity in objective loads and … …Journal of Computer Science, Vol. 9, Issue 9 · 6 Aug 2013 · 6,429 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdaptable Service Component Interface Framework in Pervasive ComputingR. Vasanthi, R. S.D. WahidabanuProblem statement: Pervasive computing refers to visionary new ways of applying Information and Communication Technologies (ICT) to our daily lives. Interoperability among pervasive networked systems, in particular accounting for the heterogeneity of protocols from the application down to the middleware layer, which is mandatory for today's and even more for tomorrow's open and highly heterogeneous networks. Approach: The high demand … …Journal of Computer Science, Vol. 8, Issue 6 · 15 Mar 2012 · 6,969 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of The Biological Integrity of The Native Vegetative Community In A Surface Flow Constructed Wetland Treating Industrial Park ContaminantsC. C. Galbrand, A. M. Snow, Abdel E. Ghaly, R. CôtéA study was conducted to evaluate the biological integrity of a constructed wetland receiving landfill leachate and stormwater runoff from the Burnside Industrial Park, Dartmouth, Nova Scotia. The biological integrity of the constructed wetland was tested in the second growing season using vegetative community monitoring. The metrics analyzed were species diversity, species heterogeneity (dominance) and exotic/invasive species abundance. There was … …OnLine Journal of Biological Sciences, Vol. 7, Issue 1 · 31 Dec 2007 · 6,998 accessesView PDFCite
Research ArticleOpen accessIn the abstractTask Load Balancing Strategy for Grid ComputingB. Yagoubi, Y. SlimaniWorkload and resource management are two essential functions provided at the service level of the Grid software infrastructure. To improve the global throughput of these environments, effective and efficient load balancing algorithms are fundamentally important. Most strategies were developed in mind, assuming homogeneous set of resources linked with homogeneous and fast networks. However for computational Grids we must address main … …Journal of Computer Science, Vol. 3, Issue 3 · 31 Mar 2007 · 7,605 accessesView PDFCite
Research ArticleOpen accessIn the abstractSegmentation of Exudates via Color-based K-means Clustering and Statistical-based ThresholdingAtef Zaki Ghalwash, Aliaa Abdel-Halim Youssif, Ali Mohamed Nabil AllamThis paper provides a novel approach for the problem of detecting the yellowish lesions in the eye fundus images, such as hard and soft exudates, in a fully-automated manner. To solve this problem of segmenting exudates automatically, the fundus image was first converted into the L*a*b* color space to decouple the chromaticity information of the image. Next, the fundus image … …Journal of Computer Science, Vol. 13, Issue 10 · 14 Oct 2017 · 7,725 accessesView PDFCite
