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 addressed the issue of estimating the damage caused by a computer virus. First, an individual-level delayed SIR model capturing the spreading process of a digital virus is derived. Second, the damage inflicted by the virus is modeled as the sum of the economic losses and the cost for developing the antivirus. Next, the impact of different factors, including the delay and the network ...

fertilization involves direct interaction of the sperm and oocyte, fusion of the cell membranes and :union: of male and female gamete genomes. the completion of this process and subsequent embryo development depend in part on the inherent integrity of the sperm dna. sperm genome quality has been emphasized for several years as playing a major role in early embryogenesis. there is clinical evide...

In much of the central and eastern United States, tree damage is typically the most common damage indicator available to National Weather Service meteorologists estimating wind speeds from convective storms. Unfortunately, most meteorologists have little or no formal training in the susceptibility of trees to high winds, and the Enhanced Fujita scale does not address many of the various factors...

Development of disaggregate models for estimating different property damage collision type frequencies in urban intersections has rarely been studied, particularly in Iran. It seems very little research work being implemented for studying the effect factors on collision type frequency at intersections. The main objective of this paper is to develop suitable statistical models to predict types o...
