conclusions the findings of this study indicated that the economic burden of tbis was high in fatal accidents in fars province so that it was equivalent to 0.00011% of iran’s gross domestic product (gdp) in 2013. therefore, more attention has to be paid to the rules to prevent the fatal accidents. results deaths resulting from tbis due to traffic accidents in shiraz imposed 6.2 billion rials (5...

We analyze the impact of public health policy on spread a disease using version SIR model that includes vital statistics, waning immunity, and vaccination. This is rich enough to accommodate endemic steady states disease-free states. choose social distancing vaccines maximize an objective function penalizes lost output resulting from distancing, deaths disease, cost Surprisingly, even though eq...

The regional economic burdens of obesity have not been fully quantified. This study incorporated bariatric surgery demographics collected from a large university hospital with regional economic and employment data to evaluate the cost of obesity for the South Plains region of Texas. Data were collected from patients who underwent laparoscopic gastric bypass and laparoscopic banding between Sept...

road traffic accidents and the effects they subsequently incur are increasing dramatically, and estimating the cost of road traffic crashes could be a vital step in improving the recognition of this widespread problem. the main objective of this paper is to estimate the cost of road traffic crashes in iran using the human capital (hc) method. results of this study indicate that the cost of road...

This paper deals with an approximation for the fraction of lost units in the slotted-output M/D/s/s+B queue with finite buffer of capacity B. To this end, the concept of equivalent load is re-introduced to easily estimate the fraction of lost units. The proposed estimation is tested in a ATM environment where the M/D/s/s+B queue is applied to give a first approach to the Cell-Loss-Rate (CLR) in...
