Growing waves in drifted plasmas

Self-consistent wave solutions for structures consisting of drifting plasmas and dielectrics are presented and the appearance of growing waves in one of the models is shown. The role of collisions and diffusion is discussed and the direction of future work aimed at devices is indicated. The requirement for velocity matching implies that eventually periodic structures and space harmonics are nee...

Compile-Time Garbage Collection by Necessity Analysis

This paper gives a brief overview of an analysis technique for determining at compile-time whether heap cells are still needed at a particular point in the execution of a functional program. This technique involves the analysis of necessity information. The analysis technique is used to determine at compile-time which heap cells can be deallocated, and also which of these deallocated cells can ...

Rates of Convergence of Diffusions with Drifted Brownian Potentials

We are interested in the asymptotic behaviour of a diffusion process with drifted Brownian potential. The model is a continuous time analogue to the random walk in random environment studied in the classical paper of Kesten, Kozlov, and Spitzer. We not only recover the convergence of the diffusion process which was previously established by Kawazu and Tanaka, but also obtain all the possible co...
