Research ArticleOpen accessEvery word in the titleModeling Heterogeneity in Phase II Clinical TrialsChristopher N. Barnes, Shesh N. RaiProblem statement: The common assumption in non-randomized Phase II clinical trials is a homogeneous population with homogeneous response. This assumption is at odds with many trials today; a heterogeneous response due to the existence of subgroups. Approach: In order to examine the effects of heterogeneity on the trial outcome, a systematic platform is developed to quantify the range and classes … …Current Research in Biostatistics, Vol. 1, Issue 1 · 30 Jun 2010 · 10,127 accessesView PDFCite
Research ArticleOpen accessIn the keywordsHeterogeneities and Intra Sand-Body Compartmentalization in Late Oligocene Delta-Front Deposit, Niger Delta, NigeriaRaphael Oaikhena Oyanyan, Michael Ndubuisi OtiThis paper presents the study of the heterogeneity in lithofacies, porosity, permeability, mineral grain density, pore-throats sizes and hydraulic rock types and the intra sand-body compartmentalization in cored delta-front deposit of Greater Ughelli depobelt of Niger Delta. Sedimentological study of core samples results in the identification of nine lithofacies and the interpretation of environments of deposition as mainly proximal and … …Current Research in Geoscience, Vol. 6, Issue 1 · 28 Mar 2016 · 8,090 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSedimentology and Ichnology of Late Oligocene Delta Front Reservoir Sandstone Deposit, Greater Ughelli Depobelt, Niger DeltaRaphael Oaikhena Oyanyan, Michael Ndubuisi OtiSedimentological and ichnological study of cored reservoir sands correlated with wireline logs between two wells, 0.8 km distance apart along dip direction, enabled vertical and cross sectional facies variability assessment aimed at determining intra sand-body continuity in longitudinal or down-dip direction; and sub-environments of deposition and factors that controlled depositional processes. Ten lithofacies described 62 meters cores of the reservoir … …Current Research in Geoscience, Vol. 5, Issue 1 · 30 Jul 2015 · 7,829 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSEMANTIC CONFLICTS DETECTION OF HETEROGENEOUS MESSAGES OF WEB SERVICES: CHALLENGES AND SOLUTIONWan Nurhayati Wan Ab. Rahman, Rodziah Atan, Abdul Azim Abdul Ghani, Ibrahim Ahmed Al-BaltahService Oriented Architecture (SOA) is a new design style that has promised to alleviate the semantic interoperability problem between Web services. Exchanging the messages seamlessly between heterogeneous Web services is required but, it is still difficult due to data heterogeneity. As a result, a noticeable number of works has been proposed with the aim of solving this problem, but yet, … …Journal of Computer Science, Vol. 10, Issue 8 · 22 Mar 2014 · 7,720 accessesView PDFCite
Research ArticleOpen accessIn the keywordsENERGY EFFICIENT AND INTERFERENCE AWARE PROVISIONING IN VIRTUALIZED SERVER CLUSTER ENVIRONMENTMohan Raj Velayudhan Kumar, Shriram RaghunathanIT service providers, employ server virtualization as a main building block to improve system utilization, improve system manageability, reduce operational costs which includes energy consumption driving economies of scale with shared resources. Virtualization enables co-locating and efficient assignments of virtual servers within the bounds of limited number of heterogeneous physical servers, with Virtual Machines (VM) sharing the limited physical server … …Journal of Computer Science, Vol. 10, Issue 1 · 12 Nov 2013 · 6,692 accessesView PDFCite
Research ArticleOpen accessIn the keywordsNumerical Modeling of Periodic Pumping Tests in Wells Penetrating a Heterogeneous AquiferPeter A. Fokker, Joerg Renner, Francesca VergaThis study investigated how to utilize multiple frequency components of pressure data from periodic pulse tests to estimate the intra-well permeability and compressibility distribution and also the presence of heterogeneities in a real field case. Periodic well testing is a technique in which injection or production pulses of a fluid are applied to a well in a periodic fashion. One … …American Journal of Environmental Sciences, Vol. 9, Issue 1 · 13 Jan 2013 · 7,990 accessesView PDFCite
Research ArticleOpen accessIn the keywordsModeling Load Balancing in Heterogeneous Unstructured P2P SystemsZhi Jun Li, Ming Hong LiaoLoad balancing is a generally concerned problem in peer-to-peer (P2P) systems. Many researches on load balancing in the structured P2P systems have been launched currently, such as Chord or other DHTs. Although the researches on load balancing in unstructured P2P systems are emerged nowadays, the simple mechanisms achieved can only perform effectively in uniform environment. In this study, the influence … …Journal of Computer Science, Vol. 1, Issue 3 · 30 Sep 2005 · 6,783 accessesView PDFCite
Research ArticleOpen accessIn the keywordsOntoJob Query Processor: An Ontology Driven Query Processing Method in Jobology Information SystemRanjna Jain, Neelam DuhanThere are a large numbers of jobsites/job portals that provide information about employment on the internet. These websites facilitate employers to post job lists. Job seekers go through those job posts and apply for the same. But, due to the availability of dozens of job portals, job seekers are unable to concentrate on the efforts to see the best outcomes. … …Journal of Computer Science, Vol. 16, Issue 5 · 11 Jan 2021 · 6,419 accessesView PDFCite
Research ArticleOpen accessIn the keywordsUSING MOBILE AGENTS FOR LOAD BALANCING IN PEER-TO-PEER SYSTEMS HOSTING VIRTUAL SERVERSVijayaKumar G. Dhas, S. Saibharath, V. Rhymend UthariarajThis study proposes a novel load-balancing algorithm for managing virtual servers in a Peer-To-Peer (P2P) system through mobile agents. The proposed algorithm is implemented in a fully decentralized manner for a structured P2P system. It uses mobile agents and is independent of the geometry of the P2P auxiliary networks. The load-balancing algorithm effectively reduces the load imbalance of the system … …Journal of Computer Science, Vol. 10, Issue 6 · 27 Jan 2014 · 6,353 accessesView PDFCite
Research ArticleOpen accessIn the abstractHybrid Fog Resource Provisioning and Resource Allocation using MKFCM and FPANagarjun E, Dharamendra Chouhan, Dilip Kumar SMThe expansion of Internet of Things (IoT) deployments has motivated the Fog Computing (FC) paradigm, which brings mobile-edge and cloud resources together under a single model. Allocating and provisioning application tasks across such environments poses challenges due to constrained resource capabilities, heterogeneity, mobility, network hierarchy, and unpredictability. This paper addresses the need for additional computing devices that prioritize delay-sensitive applications … …Journal of Computer Science, Vol. 22, Issue 10 · 6 Oct 2026 · 462 accessesView PDFCite
