Research ArticleOpen accessIn the abstractRheological Characterization of Sludge Coming from a Wastewater Treatment PlantDaniel Novarino, Ezio Santagata, Davide Dalmazzo, Mariachiara ZanettiProblem statement: The aim of this study was that of studying the rheology of sewage sludge using two different rheological test protocols taken from literature and comparing them in order to evaluate which useful information are given from every protocol. Approach: Two different protocols have been used taking particularly into account the problems connected to sludge heterogeneous composition and to … …American Journal of Environmental Sciences, Vol. 6, Issue 4 · 31 Aug 2010 · 7,365 accessesView PDFCite
Research ArticleOpen accessIn the abstractIndoor Positioning System Using Artificial Neural NetworkHamid Mehmood, Nitin K. Tripathi, Taravudh TipdechoProblem statement: Location knowledge in indoor environment using Indoor Positioning Systems (IPS) has become very useful and popular in recent years. A number of Location Based Services (LBS) have been developed, which are based on IPS, these LBS include asset tracking, inventory management and security based applications. Many next-generation LBS applications such as social networking, local search, advertising and geo-tagging … …Journal of Computer Science, Vol. 6, Issue 10 · 30 Aug 2010 · 8,838 accessesView PDFCite
Research ArticleOpen accessIn the abstractTowards An XML-Based Normalization for Healthcare Data ExchangesI. El Azami, M. M.O. Cherkaoui, C. TahonProblem statement: Most of healthcare data exchanges are textual, poorly structured and often not accessible by clinical professionals. Otherwise, the variety of medical applications and medical standards makes difficult sharing and communicating healthcare data in a highly heterogeneous environment. Approach: XML and related standards (XML schema, XSL) provided an infrastructure that might change the situation. Our aim in this study … …Journal of Computer Science, Vol. 6, Issue 7 · 31 Jul 2010 · 7,402 accessesView PDFCite
Research ArticleOpen accessIn the abstractImmunodeficiency Provides Partial Protection from Bone Loss Induced by Castration and OvariectomyCedo M. Bagi, Edwin Berryman, Nels Hanson et al.Problem Statement: The interaction of osteoblasts and osteoclasts with cells of the immune system has been suggested as a contributing factor in the development of osteoporoses. Evidence from studies in rodents suggests that T cells play a significant role in bone loss following estrogen deficiency. The goal of this study was to investigate whether the lack of functional T cells … …Current Research in Medicine, Vol. 1, Issue 1 · 30 Jun 2010 · 7,074 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Studies about Phonological Deficit Theory in Children with Developmental Dyslexia: ReviewDr. Emrah CaylakProblem statement: Developmental Dyslexia (DD) or Reading Disability (RD) that was part of a larger heterogeneous group of learning disorders and characterized by unexpected problems in academic performance, despite average intelligence. Approach: Current opinions on the biological basis of dyslexia pointed to problems with phonological processing deficits with resulting poor phonemic awareness. Though there was much support for this hypothesis … …Neuroscience International, Vol. 1, Issue 1 · 30 Jun 2010 · 14,966 accessesView PDFCite
Research ArticleOpen accessIn the abstractHomogeneous Bubbles during Jet Impingement QuenchingM. A. Islam, S. F. AhmedProblem statement: Jet impingement quenching has a very effective and large cooling potential and is a very effective means of cooling for many applications. It gives rise to heterogeneous and/or homogeneous nucleation of bubbles, which is yet to be explored. Approach: Analytically investigate the phenomenon that happened during a brief contact of a water jet impinging on a hot surface. … …American Journal of Applied Sciences, Vol. 7, Issue 6 · 30 Jun 2010 · 7,162 accessesView PDFCite
Research ArticleOpen accessIn the abstractObject Based Middleware for Grid ComputingS. Muruganantham, P. K. Srivastha, KhanaaProblem statement: "Grid" computing has emerged as an important new field, distinguished from conventional distributed computing by its focus on large-scale resource sharing, innovative applications and, in some cases, high-performance orientation. The role of middleware is to ease the task of designing, programming and managing distributed applications by providing a simple, consistent and integrated distributed programming environment. Essentially, middleware is … …Journal of Computer Science, Vol. 6, Issue 3 · 31 Mar 2010 · 7,339 accessesView PDFCite
Research ArticleOpen accessIn the abstracte-Learning Management System Using Service Oriented ArchitectureMohammed A. Jabr, Hussein K. Al-OmariProblem statement: Service Oriented Architecture (SOA) defines how to integrate widely disparate applications for a world that is Web based and uses multiple implementation platforms. Using (SOA) one can build durable e-learning contents, regardless of changes or evolutions in technology. This means that new content should be added to existing content without costly redesign, reconfiguration, or recoding. Approach: In this … …Journal of Computer Science, Vol. 6, Issue 3 · 31 Mar 2010 · 9,024 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental Evaluation of Bottleneck Link Utilization with New-Additive Increase Multiplicative Decrease Congestion Avoidance and Control AlgorithmHayder Natiq Jasem, Zuriati Ahmad Zukarnain, Mohamed Othman, Shamala SubramaniamProblem statement: As the Internet becomes increasingly heterogeneous, the issue of congestion control becomes ever more important. And the link utilization is one of the important things in term of congestion avoidance and control mechanisms. And we can define the utilization as simply the throughput divided by the access rate. And also all the developments for the congestion control and … …Journal of Computer Science, Vol. 5, Issue 12 · 31 Dec 2009 · 7,133 accessesView PDFCite
Research ArticleOpen accessIn the abstractLoad Allocation Model for Scheduling Divisible Data Grid ApplicationsMonir Abdullah, Mohamed Othman, Hamidah Ibrahim, Shamala SubramaniamProblem statement: In many data grid applications, data can be decomposed into multiple independent sub-datasets and distributed for parallel execution and analysis. Approach: This property had been successfully employed by using Divisible Load Theory (DLT), which had been proved as a powerful tool for modeling divisible load problems in data-intensive grid. Results: There were some scheduling models had been studied … …Journal of Computer Science, Vol. 5, Issue 10 · 31 Oct 2009 · 6,900 accessesView PDFCite
