Research ArticleOpen accessIn the abstractAn Application of Combined Model for Tehran Metropolitan Area Incorporating Captive Travel BehaviorShahriar A. Zargari, Morteza Araghi, Kouros MohammadianTo overcome deficiencies of the sequential transportation planning approach, this research applies a Combined Trip Distribution and Assignment Model (CTDAM) for the simultaneous prediction. The proposed combined model can itself be reformulated as an Equivalent Minimization Problem (EMP). When applying the Evans algorithm to the EMP, the CTDAM is expected to be usable in a realistic application. The objective of … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 7,855 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Fuzzy Mathematical Programming Approach to DEA ModelsA. Azadeh, S.F. Ghaderi, Z. Javaheri, M. SaberiEvaluating the performance of activities or organizations by traditional Data Envelopment Analysis (DEA) as efficiency frontier analysis models requires crisp input/output data. However, in real-world problems inputs and outputs are often imprecise. This study develops DEA models using imprecise data represented by fuzzy sets. An important outcome of assessing relative efficiencies within a group of Decision Making Units (DMUs) in … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 7,223 accessesView PDFCite
Research ArticleOpen accessIn the abstractAsymptotic Confidence Limits for a Repairable System with Standbys Subject to Switching FailuresJau-Chuan Ke, Ssu-Lang LeeThis paper studies system performance measures and asymptotic confidence limits for the mean time to failure, steady-state availability, steady-state failure frequency of a repairable system which two primary units, two standby units, and one repair facility when switching to standbys may fail. …American Journal of Applied Sciences, Vol. 4, Issue 11 · 30 Nov 2007 · 6,922 accessesView PDFCite

Research ArticleOpen accessAll words, across the recordEngaging People who Drive Execution and Organizational PerformanceOlogbo C. Andrew, Saudah SofianProblem statement: The construct of employee engagement had gained much reputation in recent years among reputable management and human resources consulting firms. Though there is an increasing contributions of few academic research on the construct of employee engagement yet there is a shortage of academic studies on the construct. This gap had made the construct an interesting area of research. … …American Journal of Economics and Business Administration, Vol. 3, Issue 3 · 3 Nov 2011 · 8,259 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEfficiency and Forecast Performance of Commodity Futures MarketsBernardina Algieri, Matthias KalkuhlThe present study empirically investigates market efficiency and the potential factors of inefficiency in the main non-energy commodity futures markets: maize, soybeans and wheat. With efficient markets, futures prices can be used as commodity price forecasts, with inefficient markets futures prices are not able to predict spot prices. Technically, exploring the drivers of inefficiency means to assess the determinants of … …American Journal of Economics and Business Administration, Vol. 11, Issue 1 · 10 Jun 2019 · 8,375 accessesView PDFCite

HughesProblem statement: In most countries of the world where there are legislation or guidelines pertaining to the commercial farming of domestic swine, figures are quoted for minimum space allocation for various ages and life stages of the animals. These figures are generally based on professional judgment and are in common usage, but there is a growing trend and an expectation … …American Journal of Animal and Veterinary Sciences, Vol. 7, Issue 2 · 4 Jun 2012 · 8,787 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordImportance of blood gas measurements in perinatal asphyxia and alternatives to restore the acid base balance status to improve the newborn performanceH. Orozco-Gregorio, D. Mota-Rojas, M. Alonso-Spilsbury et al.Prolonged or intermittent asphyxia in utero and during farrowing weakens piglets and renders them less capable of adaptation to extrauterine life. Piglets with lesser viability at birth have increased blood pCO2 and blood lactic acid concentrations and decreased blood pH. Moreover, the ability to thermoregulate during an acute cold stress is inversely related to umbilical blood lactate concentrations. Blood gas … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 3 · 30 Sep 2007 · 7,631 accessesView PDFCite
