In this paper, we present a data-driven method for crowd simulation with holonification model. With this extra module, the accuracy of simulation will increase and it generates more realistic behaviors of agents. First, we show how to use the concept of holon in crowd simulation and how effective it is. For this reason, we use simple rules for holonification. Using real-world data, we model the...

needle insertion is a minimally invasive technique in diagnosing and treating tumors. however, to perform a surgery accurately, the tissue should have minimum amount of displacement during needle insertion so that it reaches the target tissue. therefore, the tissue membrane has to move less to decrease rupturing under the membrane. in this study, the effect of different design parameters on dis...

many health studies were interested to find the association between multiple predictors with a dependent variable. the popular method to analyze these studies was multiple regressions that assumed the predictors were independent. while in practice some predictors may depend on each other and they could not be presented in a regression model simultaneously, as a result the appropriate models suc...

karun river is the largest and most watery river in iran. this river is the longest river which located just inside iran and ahvaz metropolis drinking water supplied from karun river as well (fa.alalam.ir). karun river as the main source of water treatment plants in ahvaz, like most surface waters affected by various contaminants which caused changes in water quality of the river (www.aww.co.ir...

â â â  â â â â â  the aim of this paper is to simulate the effects of some macroeconomic policy tools on production and inflation of iran by the current worldwide financial and real crisis. the theoretical framework of the analysis is based on the so-called ‘imf/world bank integrated model’ which is the synthesis (a merger) of the basic monetary approach of the balance of payments used at t...

   In this paper we propose a simulation study to carry out dynamic analysis of CNTFET-based digital circuit, introducing in the semi-empirical compact model for CNTFETs, already proposed by us, both the quantum capacitance effects and the sub-threshold currents. To verify the validity of the obtained results, a comparison with Wong model was carried out. Our mode...

in this paper, we introduce a hybrid approach based on neural network and optimization teqnique to solve ordinary differential equation. in proposed model we use heyperbolic secont transformation function in hiden layer of neural network part and bfgs teqnique in optimization part. in comparison with existing similar neural networks proposed model provides solutions with high accuracy. numerica...

always allocate man - machine is considered as one of the main concerns of operation planners. utilize an appropriate using of workforce in situations that the operation is dependent on the capabilities of the workforce, can lead to improve the systems efficiency and productivity indicators. since these issues, categories in np-hard problems, so optimization and solving the mathematical model o...
