Preliminary notes A research was conducted, for the paper, in two countries in the South-Eastern Europe region, at multiple pedestrian crossing locations in order to determine the value of motorist yield rate (MYR). The data gathered at 32 locations were used to define a mathematical model for MYR depending on location characteristics and vehicular and pedestrian traffic flow characteristics. U...

  In order to quantitatively evaluate the sediment yield in ungauged basins, it is necessary to use empirical models. The EPM model, as a model which is using in Iran, has sometimes been evaluated. Most evaluations have often been conducted by using river's sediment information and direct measurements of dam reservoir sedimentation have been less used, while the sediment measurement method on r...

This paper describes a new manufacturing yield model for submicron VLSI circuits. This model attempts to handle process induced differences between IC layout and actual IC topography. The presented model focuses on the random nature of over and under etching phenomenon. The relevance of the new yield model in submicron domain is analyzed. Examples of yield calculations using the proposed model ...

using crop simulation models is an efficient complement to experimental research. crop models can also be helpful with respect to decision-making in sustainable farming system. this study was done to estimate genetic coefficients and evaluate performanced dssat in prediction of development, growth and yield in wheat. data from various field experiments for four wheat cultivars koohdasht, shirou...

This paper considers a multi-objective portfolio selection problem imposed by gaining of portfolio, divided yield and risk control in an ambiguous investment environment, in which the return and risk are characterized by probabilistic numbers. Based on the theory of possibility, a new multi-objective portfolio optimization model with gaining of portfolio, divided yield and risk control is propo...

introduction: limited water resources and its salinity uptrend has caused reducing water and soil quality and consequently reducing the crop production. thus, use of saline water is the management strategies to decrease drought and water crisis. furthermore, simulation models are valuable tools for improving on-farm water management and study about the effects of water quality and quantity on c...

Much effort has been devoted to the synthesis of gold nanoparticles with different shapes, including the zero-dimensional nanospheres, one dimensional nanorods, and two-dimensional nanoplates. Compared to zero or one dimensional nanostructures, the synthesis of two-dimensional nanostructures in high yield has always been more involved, often requiring complex and timeconsuming steps such as mor...

Modeling plant response to salinity and nitrogen deficiency is very important for estimating optimum yield in arid and semi-arid regions. For this purpose, the models of Leibig-Sprengel (LS) and Mitscherlich-Baule (MB) originally proposed to explain plant response to nutrients only were modified to evaluate plant yield response to combined nitrogen and salinity stress conditions. Afterwards, in...
