Research ArticleOpen accessAll words, across the recordA 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 accessAll words, across the recordReservoir Oscillations with Through FlowA.A. KhanThe two-reservoir problem with through flow is a common feature in wastewater treatment plants. The start of the through flow may cause water surface oscillations in the reservoirs and velocity variations in the connecting pipe during the initial unsteady phase that may adversely affect the operation and under certain conditions may cause overtopping of the upstream reservoir. The classical solution … …American Journal of Environmental Sciences, Vol. 3, Issue 1 · 31 Mar 2007 · 7,030 accessesView PDFCite

Mills, A. ElchouemiInformation about the distribution of path-lengths in a Binary Decision Diagrams (BDDs) representing Boolean functions is useful in determining the speed of hardware and software implementations of the circuit represented by these Boolean functions. This study presents expressions produced from an empirical analysis of a representative collection of Boolean functions. The Average Path Length (APL) and the Shortest Path Length … …Journal of Computer Science, Vol. 2, Issue 3 · 31 Mar 2006 · 6,814 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordGroundwater Resources Management in Various Scenarios Using Numerical ModelS. Askari Marnani, M. Chitsazan, Y. Mirzaei, B. JahandidehProblem statement: Iran is an arid country and only small percent of its water demand is met by rainfall. At present, about 55% of Iran's water being supplied by aquifers and 45% from surface water. Population growth, joint with economic development and rapid growth in industry and farming, has caused a vast increase in demand for water in Iran. But … …Current Research in Geoscience, Vol. 1, Issue 1 · 30 Jun 2010 · 13,769 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordAnalysis of Motion of Partial System on Phase Plane and Determination of Stable Cutting RegionsFiras Al Qura'nTurning is one of the most efficient preferred and cutting processes currently known. It was a challenging task for researchers to study the different dynamic properties explores its special dynamical properties, including conditions that insure the stability of the cutting process and the associated nonlinear vibrations. The main goal of this study was to develop and study a simple model, … …American Journal of Applied Sciences, Vol. 4, Issue 1 · 30 Apr 2007 · 6,822 accessesView PDFCite
