A database on the rain rate collected with disdrometers at various sites located from the middle to tropical latitudes is used to analyze the variations of the parameters of the probability density ...

This paper presents correction terms to the tangent approximation for the first-exit density of Brownian motion at distant boundaries. These lead to second-order approximations to the first-exit ...

Monte Carlo variance reduction techniques have become indispensable in radiation transport simulations, where the challenge of obtaining statistically significant results in deep-penetration problems ...
