Research ArticleOpen accessAll words, across the recordResponse Time Optimization for Replica Selection Service in Data GridsHusni H.E. AL-Mistarihi, Chan H. YongProblem Statement: Data Grid architecture provides a scalable infrastructure for grid services in order to manage data files and their corresponding replicas that were distributed across the globe. The grid services are designed to support a variety of data grid applications (jobs) and projects. Replica selection is a high-level service that chooses a replica location from among many distributed replicas … …Journal of Computer Science, Vol. 4, Issue 6 · 30 Jun 2008 · 6,495 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordESTIMATION OF AQUIFER PARAMETERS IN ERHO, NIGERIA USING THE COOPER-JACOB EVALUATION METHODOchuko Anomohanran, Ruth E. Iserhien-EmekemeThe aim of this study was to determine the aquifer parameters in Erho, Nigeria. This was carried out by drilling three test wells and three observation wells in the study location. Water was pumped from the test wells at a constant rate while the drawdown in the observation wells was determined as a function of time. The data obtained were … …American Journal of Environmental Sciences, Vol. 10, Issue 5 · 12 Nov 2014 · 6,910 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordESTIMATIONS OF TOTAL MASS AND ENERGY OF THE OBSERVABLE UNIVERSEDimitar ValevThe recent astronomical observations indicate that the expanding universe is homogeneous, isotropic and asymptotically flat. The Euclidean geometry of the universe enables to determine the total gravitational and kinetic energy of the universe by Newtonian gravity in a flat space. By means of dimensional analysis, we have found the mass of the observable universe close to the Hoyle-Carvalho formula M∼c3/(GH). … …Physics International, Vol. 5, Issue 1 · 21 Mar 2014 · 17,696 accessesView PDF Cite
