Research ArticleOpen accessIn the abstractModeling 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 · 10,131 accessesView PDFCite
Research ArticleOpen accessIn the abstractDairy Heifer Rearing in Hot Arid Zone: An Economic AssessmentM. A. Razzaque, S. A. Mohammed, T. Al-MutawaProblem statement: Economic losses due to high mortality in young calves born in hot arid zone including Kuwait and a high cost of rearing are the main constraints to this region. Therefore, dairy producers have to depend on importation of pregnant heifers for herd replacement. Research data on cost of heifer rearing from their weaning to first lactation were lacking. … …American Journal of Applied Sciences, Vol. 7, Issue 4 · 30 Apr 2010 · 7,547 accessesView PDFCite
Research ArticleOpen accessIn the abstractGreen Methodologies to Test Hydrocarbon ReservoirsFrancesca Verga, Vera RoccaProblem statement: The definition and the economic viability of the best development strategy of a hydrocarbon reservoir mainly depend on the quantity and type of fluids and on the well productivity. Well testing, consisting in producing hydrocarbon to the surface while measuring the pressure variations induced in the reservoir, has been used for decades to determine the fluid nature and … …American Journal of Environmental Sciences, Vol. 6, Issue 1 · 28 Feb 2010 · 7,643 accessesView PDFCite
Research ArticleOpen accessIn the abstractDistributed Real Time Architecture for Data Placement in Wireless Sensor NetworksSanjeev Gupta, Mayank DaveProblem statement: Application scenarios of Wireless Sensor Networks (WSN) create interesting design challenges since the sensor nodes used to collect and communicate data may fail suddenly and unpredictably. The issue of real-time and reliable data delivery is extremely important for taking effective decisions in WSN. Approach: In this study we proposed architecture for reliable and real-time approach for data placement … …Journal of Computer Science, Vol. 5, Issue 12 · 31 Dec 2009 · 6,638 accessesView PDFCite
Research ArticleOpen accessIn the abstractTowards the Development of Speaker-Dependent and Speaker-Independent Hidden Markov Model-Based Thai Speech SynthesisSuphattharachai ChomphanProblem statement: Tone distortion in Thai languages can deteriorate not only the intelligibility of speech but also its naturalness. Therefore, the correctness of tone must be carefully taken into account in continuous speech synthesis. The preliminary work confronted this problem when applying HMM-based speech synthesis to Thai. Approach: This study presented a study on speaker-dependent and speaker-independent Hidden Markov Model … …Journal of Computer Science, Vol. 5, Issue 12 · 31 Dec 2009 · 6,928 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Cost Effective and User Friendly Approach to Design Wireline Formation TestsClara Bertolini, Giuseppe Tripaldi, Elena Manassero et al.Problem statement: Wireline formation testing (also named Mini-DSTs) are gaining more and more popularity as a possible alternative to conventional well testing especially where there are major environmental and economical constraints. The increased offshore exploration activity, which often implies highly risky and huge operational costs, makes the conventional well testing less attractive in favor of other technologies that can provide … …American Journal of Environmental Sciences, Vol. 5, Issue 6 · 31 Dec 2009 · 6,669 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproving Performance of Replacement Heifers in Hot Arid Environment Under Intensive ManagementM. A. Razzaque, S. A. Mohammed, T. Al- Mutawa, M. BedairProblem statement: Imported Holstein Friesian dairy cattle are exposed to hot arid climate in feedlot management in Kuwait. Desert climate is extreme reaching high 45-50°C in summer and low -4ºC in winter at day and night respectively. High calf mortality, poor reproduction and milk yields were main constraints to viable dairying. The objectives of this study were to assess the … …American Journal of Animal and Veterinary Sciences, Vol. 4, Issue 4 · 31 Dec 2009 · 6,986 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Performance Study of Reactive Multicast Routing Protocols in Virtual Class Room Using Mobile Ad Hoc NetworkS. Vijayaragavan, K. Duraiswamy, B. Kalaavathi, S. MadhaviProblem statement: A great deal of excitement has recently propelled Mobile Learning to the forefront of educational technology. The exponential growth of mobile technology in the recent years, increase in the availability of high-bandwidth network, advances in wireless technologies and popularity of handheld devices, have opened up new accessibility opportunities for education. Approach: Virtual class room using MANET had been … …Journal of Computer Science, Vol. 5, Issue 11 · 30 Nov 2009 · 6,879 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Simulation Model Estimates of the Intercropping Advantage of an Immature-Rubber, Banana and Pineapple SystemMohamadu Boyie Jalloh, Wan Sulaiman Wan Harun, Jamal Talib et al.Problem statement: Intercropping has been shown to have many advantages but it is fallacious to conclude it is always a better cropping system. Little is known about a new double-hedgerow intercropping of rubber, banana and pineapple in relation to its effects on growth and yield of the component crops when compared to their monocrops. Simulation modeling offers a cheaper and … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 3 · 30 Sep 2009 · 9,005 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalyzing the Effects of Water and Agriculture Policy Strategies: An Iranian experienceReza Moghaddasi, Ali Bakhshi, Mahmood Daneshvar KakhkiProblem statement: Because of growing demand for water resources, increasing cost of supplying water and overdraft of underground waters, economists suggest water pricing policy to improve water allocation efficiency in Iran. While due to political risk, economic and cultural concerns, government tends to reject that advice. This study addressed questions of what policy alternatives to water pricing could be used … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 3 · 30 Sep 2009 · 8,308 accessesView PDFCite
