Research ArticleOpen accessIn the abstractConstrained Probabilistic Lost Sales Inventory System with Normal Distribution and Varying Order CostHala, A. Fergany, Mona, F. EL-WakeelThis study derives the probabilistic lost sales inventory system when the order cost is a function of the order quantity. Our objective is to minimize the expected annual total cost under a restriction on the expected annual holding cost when the lead-time demand follows the normal distribution by using the Lagrangian method. Then a published special case is deduced and … …Journal of Mathematics and Statistics, Vol. 2, Issue 1 · 31 Mar 2006 · 7,198 accessesView PDFCite
Research ArticleOpen accessIn the abstractConstrained Single Period Stochastic Uniform Inventory Model With Continuous Distributions of Demand and Varying Holding CostHala A. Fergany, M. E. El-SaadaniThis paper derives the single period stochastic inventory model with continuous distributions of demand and the holding unit cost is a function of the purchased (ordered) quantity. The objective is to find the optimal purchased quantity which minimizes the expected total cost for the period under a restriction on the expected varying holding cost when the demand during the period … …Journal of Mathematics and Statistics, Vol. 2, Issue 1 · 31 Mar 2006 · 7,159 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign of a Neural Networks Classifier for Face DetectionF. Smach, M. Atri, J. Mitéran, M. AbidFace detection and recognition has many applications in a variety of fields such as security system, videoconferencing and identification. Face classification is currently implemented in software. A hardware implementation allows real-time processing, but has higher cost and time to-market. The objective of this work was to implement a classifier based on neural networks MLP (Multi-layer Perception) for face detection. The … …Journal of Computer Science, Vol. 2, Issue 3 · 31 Mar 2006 · 6,887 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Dynamic Weight Assignment Approach for Index TermsKamel E. Haouam, Farhi MarirCurrently in the development of Informational Retrieval (IR) systems, a set of keywords represents the semantics of a text document and after assigning weights to the set of keywords, they are used for indexing, searching and retrieval purposes. The current approaches for assigning weights are provided by an IR model that is used by an IR system. The main objective … …Journal of Computer Science, Vol. 2, Issue 3 · 31 Mar 2006 · 6,945 accessesView PDFCite
Research ArticleOpen accessIn the abstractNon-dominated Sorting Genetic Algorithms for Heterogeneous Embedded System DesignA. K. Rath, S. N. DehuriThe design of complex embedded systems involves the simultaneous optimization of several conflicting and competing objectives. Instead of a single global optimal solution, there exist a set of Pareto optimal solutions. In this study we have used a multi-objective evolutionary optimization algorithms called non-dominated sorting genetic algorithm (NSGA), which will suit to the requirements of designing a complex heterogeneous embedded … …Journal of Computer Science, Vol. 2, Issue 3 · 31 Mar 2006 · 6,694 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Development of A New, Rapid, Amperometric Immunosensor for the Detection of Low Concentrations of Bacteria Part I: Design of the Detection System and ApplicationsEric Carnes, Ebtisam WilkinsA portable, flow-through amperometric immunoassay system utilizing a newly designed immunosensor has been developed for the detection of bacteria. A sandwich scheme of immunoassay involving two stages of immunoreaction was employed using Escherichia coli as a model. E. coli antibodies were immobilized on Toray carbon paper to create a disposable immunofiltration membrane. Detection of the bacteria was achieved through the … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2006 · 6,365 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpact Analysis of Irrigation Projects: an Application of Contingent Valuation MethodAnastasios MichailidisWater supply in rural and urban areas is an issue of primary concern, especially in developing countries. The objective of this study is to estimate some socioeconomic and environmental values of three irrigation lakes, constructed at Panagitsa village (Region of Central Macedonia, Prefecture of Pella). The study area is characterized, especially during the summer session, of limited water supply for … …American Journal of Agricultural and Biological Sciences, Vol. 1, Issue 1 · 31 Mar 2006 · 7,824 accessesView PDFCite

Research ArticleOpen accessIn the abstractHow Serious Regional Economic Inequality in Jordan? Evidence from Two National Household SurveysMohammed Issa ShahateetThe objective of this study is to measure and explain the extent of regional economic inequalities in Jordan. To do so, this study uses the raw data of two national household surveys on expenditure and income that covers 5,971 and 11,153 households in 1997 and 2002, respectively. As a check on the empirical results, the study applies four measures of … …American Journal of Applied Sciences, Vol. 3, Issue 2 · 28 Feb 2006 · 7,216 accessesView PDFCite
Research ArticleOpen accessIn the abstractLaser Beam Analysis Using Image ProcessingYas A. AlsultannyThe laser beam profiles captured by CCD camera processed and analyzed by using 2D- graphic and displayed on the monitor. The analysis of the He-Ne profiles and laser diode profiles are presented. The results showed that the He-Ne laser emits a pure Gaussian beam, whereas the diode laser emits an elliptical beam shape. The laser beam profile analysis developed to … …Journal of Computer Science, Vol. 2, Issue 1 · 31 Jan 2006 · 7,526 accessesView PDFCite
