Research ArticleOpen accessIn the abstractFuel Injection Pressure Effect on Performance of Direct Injection Diesel Engines Based on ExperimentRosli Abu Bakar, Semin, Abdul Rahim IsmailFuel injection pressures in diesel engine plays an important role for engine performance obtaining treatment of combustion. The present diesel engines such as fuel direct injection, the pressures can be increased about 100 -200 Mpa bar in fuel pump injection system. The experimental investigated effects of fuel injection pressure on engine performance. Experiments have been performed on a diesel engine … …American Journal of Applied Sciences, Vol. 5, Issue 3 · 31 Mar 2008 · 8,877 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproving Quality of Clustering using Cellular Automata for Information retrievalP. K. Sree, G. V.S. Raju, I. R. Babu, S. V. RajuClustering has been widely applied to Information Retrieval (IR) on the grounds of its potential improved effectiveness over inverted file search. Clustering is a mostly unsupervised procedure and the majority of the clustering algorithms depend on certain assumptions in order to define the subgroups present in a data set .A clustering quality measure is a function that, given a data … …Journal of Computer Science, Vol. 4, Issue 2 · 28 Feb 2008 · 7,033 accessesView PDFCite
Research ArticleOpen accessIn the abstractAFLPs in Warmblood Sporting Horses: Genetic Correlation with Height at the WithersV. Sanchez, C. Lemus, A. Inchaustegui et al.The Mexican army produces Warmblood horses for jumping proposes. However, breeding is based on phenotype and stallions are selected stepwise until the end of growth, representing a high care and maintenance cost. In this work using 64 selective primer combinations and AFLP technology we identified specific molecular markers related with height at the withers measurements of Warmblood horses. AFLPs generated … …American Journal of Infectious Diseases, Vol. 3, Issue 2 · 30 Jun 2007 · 6,753 accessesView PDFCite
Research ArticleOpen accessIn the abstractHigh Concentrations of Glucose can Activate or Inhibit Human Erythrocyte Aminolevulinate Dehydratase in vitro Depending Exposure TimeJ. C. Soares, D. Gabriel, V. Folmer et al.Hyperglycemia can cause oxidative stress and inactivate susceptible enzymes. In the present investigation we examined whether short-term incubations (24 or 48 h) with high concentrations of glucose (10-200 mmol L-1) inhibit ALA-D from human erythrocytes. Incubations of erythrocytes for 24 h with glucose (10 up to 40 mmol L-1) resulted in an increase of δ-ALA-D activity (P<0,001). Incubations of erythrocytes … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 4 · 31 Dec 2006 · 6,686 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Compressing Ultrasonic Data Algorithm Based on WaveletsMounir Hergli, Jamel Baili, Faouzi Bouslama, Kamel BesbesIn this paper, we propose a novel and effective algorithm for compressing large volumes of data recorded in underwater applications, using a laboratory designed experimental setup. This data represents samples of ultrasonic signals acquired at different geometric positions of a water tank. The proposed algorithm was based on Wavelets and consists of two processing phases including a prefiltering stage using … …American Journal of Applied Sciences, Vol. 2, Issue 12 · 31 Dec 2005 · 7,000 accessesView PDFCite
Research ArticleOpen accessIn the abstractFinite Difference Solution for Precooling Process of Fish PackagesK. A. Abbas, F. A. Ansari, A. S. Mokhtar et al.The present work aims at finding an optimized finite difference scheme for the solution of problems involving pure convection heat transfer in slab shaped fresh water fish pieces. A generalized mathematical model was written in dimensionless form and an optimized scheme of the solutions was worked out. A fully explicit finite difference scheme, an implicit finite difference scheme and different … …American Journal of Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2004 · 6,901 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordOptimal Control Techniques for the Role of Antiretroviral Therapy (ART) Abuse in HIV/AIDS Treatment DynamicsBassey Echeng Bassey, Adagba Odey HenryFrom the studies of HIV/AIDS transmission and treatment dynamicsusing mathematical modeling, literature reviews have shown that attention hadnot been given to the behavioral attitude of screen-aware infectives not readyto receive treatment, HIV-aware infectives that initiated treatment buttruncated only to resume treatment later (therapy abuse) and those onconsistent treatment protocols. Moreso, following the non-outright eradicationof the deadly HI-virus, recommendations have been … …Journal of Mathematics and Statistics, Vol. 18, Issue 1 · 24 Nov 2022 · 5,819 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordNon-business E-Commerce in Malaysia: An Investigation of Key AdoptionOswald Aisat Igau, Abdul Wahid Mohd Kassim, Sulaiman Tahajuddin et al.Problem statement: Non-business EC is a relatively new research niche in the general e-commerce stream. Application of e-commerce by profit oriented organization already become bread and butter but still limited applied in non-business sectors such as academic institutions (as in the present study), non-profit organizations, religious organizations and government agencies. Nowadays e-commerce becomes crucially essential in reducing their expenses and … …American Journal of Economics and Business Administration, Vol. 3, Issue 1 · 31 Jan 2011 · 8,842 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA Neuro Fuzzy Technique for Process Grain Scheduling of Parallel JobsS. V. Sudha, K. ThanushkodiProblem statement: We present development of neural network based fuzzy inference system for scheduling of parallel Jobs with the help of a real life workload data. The performance evaluation of a parallel system mainly depends on how the processes are co scheduled? Various co scheduling techniques available are First Come First Served, Gang Scheduling, Flexible Co Scheduling and Agile Algorithm … …Journal of Computer Science, Vol. 7, Issue 8 · 14 Jul 2011 · 6,457 accessesView PDFCite
