the objective of this study was to evaluate the ability of ten gcms and three emission scenarios to reproduce the rainfall and temperature parameters in kermanshah, ravansar and west islamabad stations located inside qaresou basin in iran using the average weighting method, over 1989-2008 period. at first, the models output and the scenarios were provided for this period. then, the models valid...
The sensitivity analysis for multi-attribute decision making (MADM) problems is important for two reasons: First, the decision matrix as the source of the results of a decision problem is inaccurate because it sorts the alternatives in each criterion inaccurately. Second, the decision maker may change his opinions in a time period because of changes in the importance of the criteria and in the ...
in this paper, a new numerical method is presented for solvingthe optimal control problems of bang-bang type with free or xed terminaltime. the method is based on bezier polynomials which are presented inany interval as [t0; tf ]. the problems are reduced to a constrained problemswhich can be solved by using lagrangian method. the constraints ofthese problems are terminal state and conditions....
this experiment was conducted to investigate the effect of different levels of saccharomyces cerevisiae cell wall on performance, carcass traits and intestinal morphology in broilers. in this experiment 240 ross- 308 broilers were used in 4 treatments, 5 replicates and 12 bird in each replicate in a completely randomized design for 42 days. the treatments included: 1) control group (without sac...
Unitary air conditioning equipment often receives poor maintenance because there are no diagnostic sensors and the equipment owners have no real understanding of how the system operates. Maintenance is often called for only when the capacity is no longer adequate, which is usually at the time of the greatest need for the system and the busiest service time. Using a simple model of constant heat...
We propose an exact clustering with retiming algorithm to minimize the clock period for sequential circuits. Without moving ip-ops (FF's) by retiming, conventional clustering algorithms can only handle combina-tional parts and therefore cannot achieve the best cycle time. Pan et al. 2] have proposed an optimal algorithm under the unit gate delay model. We propose a more powerful and faster algo...
Introduction & Objective: Women during their lifetime experience a variety of physiological changes that can affect their physiological capacity to perform exercise and induce reduction in achieving the benefits of training. So, finding the best time to perform maximum physical performance is essential. Sports drink consumption can also help to enhance athletic performance. The purpose of thi...
The main purpose of this paper is to analyze the exchange rate volatility in Iran in the time period between 2011/11/27 and 2017/02/25 on a daily basis. As a tradable asset and as an important and effective economic variable, exchange rate plays a decisive role in the economy of a country. In a successful economic management, the modeling and prediction of the exchange rate volatility is esse...
