Research ArticleOpen accessIn the abstractFriction Forces in O-ring SealingAl-Ghathian, Faisal M.M. Tarawneh, S. MuafagIn the present study the focus was on developing a relationship as practical and convenient option for computing the friction force in O-ring sealing elements as used in the hydraulic and pneumatic equipments. For low-pressure applications, the developed relationship was applied for a different number of O-ring diameters, by investigating the obtained results, a good agreement has been observed for … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 8,465 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Development of a New, Rapid, Amperometric Immunosensor for the Detection of Low Concentrations of Bacteria Part II: Optimization of the System for Escherichia coliEric Carnes, Ebtisam WilkinsThe optimization of a flow-through immunoassay system was conducted to achieve rapid detection of low concentrations of E. coli bacteria. The system includes a new immunosensor that uses newly developed, disposable immunofiltration membranes to yield a system that is sensitive as well as simple. Comparison of the performance of this system with conventional immunoassays demonstrated a significantly shorter time for … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 6,783 accessesView PDFCite
Research ArticleOpen accessIn the abstractPotential of Rice Husk and Rice Husk Ash for Phenol Removal in Aqueous SystemsA. H. Mahvi, A. Maleki, A. EslamiThe potential of rice husk and rice husk ash for phenol adsorption from aqueous solution was studied. Batch kinetics and isotherm studies were carried out under varying experimental conditions of contact time, phenol concentration, adsorbent dose and pH. Adsorption equilibrium of rice husk and rice husk ash was reached within 6 hours for phenolic concentration 150-500 μg/L and 3 hours … …American Journal of Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2004 · 10,177 accessesView PDFCite
Research ArticleOpen accessIn the abstractNumber of Non-Unique Minors (of Various Orders) and Elements in the Calculation of General DeterminantsPatrick Marchisella, Gurudeo Anand TularamProblem statement: Many distinct properties of determinants have been studied and are known, yet a considerable number of properties still need further examination. This study investigates the number of minors (of various orders) and elements of a matrix A contained in the expansion of the general determinant of A, irrespective of the independence, principality and distinctness of such minors and … …Journal of Mathematics and Statistics, Vol. 8, Issue 3 · 13 Oct 2012 · 7,439 accessesView PDFCite
Research ArticleOpen accessIn the abstractPolicy Decisions for a Price Dependent Demand Rate Inventory Model with Progressive Payments SchemeMukesh Kumar, Rajat KumarProblem statement: In this proposed research, we developed an inventory model to formulate an optimal ordering policies for supplier who offers progressive permissible delay periods to the retailer to settle his/her account. We assumed that the annual demand rate as a decreasing function of price with constant rate of deterioration and time-varying holding cost. Shortages in inventory are allowed which … …Journal of Mathematics and Statistics, Vol. 8, Issue 1 · 17 Feb 2012 · 7,053 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Heapify Based Parallel Sorting AlgorithmM. A.A.A. Hija, A. Zabian, S. Qawasmeh, O. H.A.A. HaijaQuick sort is a sorting algorithm whose worst case running time is θ(n2) on an input array of n numbers. It is the best practical for sorting because it has the advantage of sorting in place. Problem statement: Behavior of quick sort is complex, we proposed in-place 2m threads parallel heap sort algorithm which had advantage in sorting in place … …Journal of Computer Science, Vol. 4, Issue 11 · 30 Nov 2008 · 6,769 accessesView PDFCite

Research ArticleOpen accessIn the abstractCombining ANP and TOPSIS Concepts for Evaluation the Performance of Property-Liability Insurance CompaniesHui-Yin Tsai, Bao-Huey Huang, An Siou WangThis is a significant problem for the property-liability insurance industry. The study first uses Modified Delphi Method to sift influence property-liability insurance effects out norms. Moreover, the evaluation weights are determined using Analytic Network Process (ANP). Finally, the technique for ordering preference by similarity to the ideal solution (TOPSIS) constructs performance evaluation model of property-liability insurance companies in Taiwan. This … …Journal of Social Sciences, Vol. 4, Issue 1 · 31 Mar 2008 · 8,208 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordAn Optimal Load Sharing Technique For Grid ComputingD. Ramesh, A. KrishnanProblem statement: Grid and Cloud Computing is the fast growing industry, in which the grid computing shares the resources in the organization in an effective manner. Resource sharing requires more optimized algorithmic structure, otherwise the waiting time and response time are increased and the resource utilization is reduced. Approach: In order to avoid such reduction in the performances of the … …American Journal of Applied Sciences, Vol. 9, Issue 7 · 29 May 2012 · 6,967 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA First-Class Ticket to the Planet Mars, PleaseRelly Victoria Petrescu, Raffaella Aversa, Bilal Akash et al.The paper presents some aspects related to the current stage in the aerospace industry, referring to the current possibilities of moving in space. The main problem that has kept mankind for so many millennia has been the less speed of movement, but also the difficult exit into outer space. For a ship to be able to defeat gravitational forces and … …Journal of Aircraft and Spacecraft Technology, Vol. 1, Issue 4 · 1 Dec 2017 · 7,008 accessesView PDFCite
