Background: Mothers’ delivery is one of the most common hospitalization factors throughout the world and it’s modeling can explain distribution and effective factors on rising and decreasing of it. The objective of the present study was a suitable modeling for mother hospitalization time and comparing it with different models. Materials & Methods: Present study is an observational and cross-s...

in this paper we consider the problem of delay-dependent robusth1 control for uncertain fuzzy systems with time-varying delay. the takagi–sugeno (t–s) fuzzy model is used to describe such systems. time-delay isassumed to have lower and upper bounds. based on the lyapunov-krasovskiifunctional method, a sufficient condition for the existence of a robust $h_{infty}$controller is obtained. the fuzz...

This paper considers a time dependent(the travel time is not constant throughout the day) pollution routing problem (TDPRP), which aids the decision makers in minimizing travel time, toll cost and emitted pollution cost.  In complexity of urban areas most of the time one point is accessible from another with more than one edge. In contrast to previous TDPRP models, which are designed with only ...

the aim of this study was to investigate the factors affecting timely repayment of agricultural loans in fars province. the necessary data was obtained from agricultural bank as well as through 163 questionnaires, filled out in fars-province. the farmers were divided in to timely repayment and defaulter groups while standard tobit model being used for the study. the dependent variable in this m...

in this work we investigate the thermal entanglement between two-level atoms and photons in a nonlinear cavity. we consider intensity-dependent couplings and calculate the negativity, as a measure of atom-photonentanglement. the cavity is assumed to be at a temperature t, so that all number of photons, and at the same time, both atomic states, with definite probabilities, are present. we then d...
