The damage mechanisms in sandwich plates with polymer foam cores are investigated. There has been a long-standing controversy on what is the weakest element of sandwich plates, the skin-core bonding or the foam core. Under four-point bending of a san

In this study we show how methods from the theory of stochastic processes can be applied to problems in dispersion theory. First, we show that Taylor dispersion with adsorbing boundaries is easily transformed into a new Taylor dispersion problem with

An investigation has been conducted to examine the previously observed infrared emission occurring at the end of an engine's compression period. The infrared preflame spectrum is measured and quantitatively compared with a radiation emission model in

This paper treats a simple model, which can be exactly solved, motivated by the back-and-forth motion of ocean bacteria. In particular, the probability is determined that a bacterium moving randomly along a fluid line through the origin in a linear s

We discuss the optimal Markovian coupling before an exponential time of the Kolmogorov diffusion, and a class of related stochastic control problems in which the aim is to hit the origin before an exponential time. We provide a scaling argument for t

The joint law of the integral and the maximum of a Brownian excursion Y with a single mark of an independent Poisson point process of rate is determined. We use the identity in law of Y and two independent Brownian motions with drift − u ( u >0) jo

We determine a statistic called the (radially) persistent angular structure (PAS) from samples of the Fourier transform of a three-dimensional function. The method has applications in diffusion magnetic resonance imaging (MRI), which samples the Four

We present new numerical methods for scalar stochastic differential equations. Successive time increments are independent random variables with an exponential distribution. We perform numerical experiments using a double-well potential. Exponential t
