the ever increasing rate of power consumption has led to an increase in public exposure to extremely low frequency magnetic fields (elf-mfs) and brought severe concerns about their health effects. considering previous studies and the facts about potential health effects of these fields, the present study aimed to evaluate the elf-mf flux densities from power distribution lines near hospitals in...

We develop an observation that a simulation method introduced recently for heavy-tailed stochastic simulation, namely hazard-rate twisting, is equivalent to doing exponential twisting on a transformed version of the heavy-tailed random-variable; the transforming function is the hazard function. Using this approach, the paper develops efficient methods for computing portfolio value-at-risk (VAR)...

background: natural radionuclides are always present in the environment. human exposure to the background radiation is inevitable. it is therefore important to assess health risk associated with these radionuclides. materials and methods: the distribution of natural radionuclides 238u, 232th and 40k in soil samples collected from all the twenty (20) local governments headquarter areas in ogun s...

More recently, seve­ ral methods of introducing one or more parameters to generate new distributions have been proposed. Among these methods, the compounding of some discrete and important lifetime distributions has been in the vanguard of lifetime modeling. So, several families of distributions were invest...
