Research ArticleOpen accessIn the abstractFailure Diagnosis on Discrete Event SystemsSihem Kechida, Nasr Eddine DebbacheThe modern technology advances to a point where it is possible and extensively desirable to improve reliability and the technical process safety. This is achieved by computer implanted FDI procedures (Fault Detection and Isolation). However, the malfunction of actuators, sensors and of the process components, as well as erroneous actions of human operators can have some disastrous consequences in high … …American Journal of Applied Sciences, Vol. 2, Issue 11 · 30 Nov 2005 · 6,889 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Analysis of Credit Scoring for Agricultural Loans in ThailandVisit Limsombunchai, Christopher Gan, Minsoo LeeLoan contract performance determines the profitability and stability of the financial institutions and screening the loan applications is a key process in minimizing credit risk. Before making any credit decisions, credit analysis (the assessment of the financial history and financial backgrounds of the borrowers) should be completed as part of the screening process. A good credit risk assessment assists financial … …American Journal of Applied Sciences, Vol. 2, Issue 8 · 31 Aug 2005 · 7,622 accessesView PDFCite
Research ArticleOpen accessIn the abstractOPTIMIZING AN ALUMINUM EXTRUSION PROCESSMohammed Ali HajeehMinimizing the amount of scrap generated in an aluminum extrusion process. An optimizing model is constructed in order to select the best cutting patterns of aluminum logs and billets of various sizes and shapes. The model applied to real data obtained from an existing extrusion factory in Kuwait. Results from using the suggested model provided substantial reductions in the amount … …Journal of Mathematics and Statistics, Vol. 9, Issue 2 · 23 Apr 2013 · 7,635 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnergy Consumption and Environmental Implications of Wired Access NetworksSlavisa Aleksic, Ana LovricProblem statement: Wired broadband Internet access can be realized using various technologies, configurations and protocols. It is widely deployed and able to provide both high data rates and high reliability. These features are of strong importance for many advanced applications. Since the number of broadband subscribers worldwide grows exponentially, the power efficiency of access networks becomes increasingly important. Approach: The … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 4 · 18 Jan 2012 · 8,767 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Impact of Air Pollution on Human Health: Focusing on the Rudnyi Altay Industrial AreaVitaliy G. Salnikov, Marat A. KaratayevProblem statement: Air pollution in Kazakhstan is significant environmental problem. The air pollution level of cities and industrial centers remains rather high. The highest level of air pollution is registered in Ridder, Ust-Kamenogorsk, Almaty, Zyryanovsk, Aktau, Atyrau, Shymkent, Taraz, Petropavlovsk and Temirtau. The enterprises of the Rudnyi Altay, Pavlodar Oblast and enterprises of oil and gas complex in West-Kazakhstan, Atyrau … …American Journal of Environmental Sciences, Vol. 7, Issue 3 · 21 Jul 2011 · 10,451 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Determinants of Deprivation in Jordan: Empirical StudyMohammed Issa ShahateetThe objective of this study was to determine and explain the factors that affect deprivation in Jordan. To do so, this study constructs and tests a model that determines the factors, which affect deprivation. It employs an econometric analysis to examine the relationship between some main socioeconomic variables and the status of deprivation in Jordan. It looks at how changes … …Journal of Social Sciences, Vol. 3, Issue 1 · 31 Mar 2007 · 7,598 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization of Substrate-Borne Vibrational Signals of Euschistus servus (Heteroptera: Pentatomidae)Brittany Lampson, Young Han, Ahmad Khalilian et al.Problem Statement: Stink bugs were not major pests of cotton in the southeastern United States until cotton varieties containing Bacillus thuringiensis (Bt) transgenes came into common use, enabling reductions in insecticide applications against highly destructive lepidopteran pests. To maintain the benefits of reduced insecticide applications, it would be advantageous to detect and target isolated populations of stink bugs before they … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 1 · 31 Mar 2010 · 8,275 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnti-Diabetic Activity of a Fraction from Cissus verticillata and Tyramine, its Main Bioactive Constituent, in Alloxan-Induced Diabetic RatsCleide de Sousa Lino, Thiago de P. Sales, Patrícia B. Gomes et al.Cissus verticillata (syn. C. sycioides, fam. Vitaceae) is a medicinal plant popularly used in Brazil, for the treatment of diabetes mellitus. The anti-diabetic activity of a fraction from leaves of Cissus verticilllata (MSF, methanol soluble fraction), as well as that of tyramine (TYR) were investigated, in the model of alloxan-induced diabetes, in male Wistar rats. The biochemical parameters studied were: … …American Journal of Pharmacology and Toxicology, Vol. 2, Issue 4 · 31 Dec 2007 · 8,628 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordDesigning of PID Controller for Discrete Time Linear System Using Balanced Approach Reduced Order ModelC.S. Ravichandran, S. Subha Rani, T. ManikandanModeling physical systems usually results in complex high-order dynamic models. It is often desirable to approximate these models by simpler models with reduced order. This study deals with the design of discrete time linear system using a balanced approach reduced order model. The reduced order model retains the desired state variable which contains a significant contribution. A PID controller is … …American Journal of Applied Sciences, Vol. 4, Issue 3 · 31 Mar 2007 · 7,132 accessesView PDFCite
