Diffusion Processes, Metric Graphs and Boundary Value Problems for Reaction Diffusion Systems
… model of a class of first order reaction-diffusion system, known as TAP systems, in which gas reactants and products diffuse in a domain and reaction takes place at a single relatively small catalytic site in the domain. The central problem is to determine the probability of reaction, or, …

Thermal Diffusion and Flame Structure in a Laminar Hydrogen Jet Diffusion Flames
… flames were used to evaluate the thermal diffusion model. In addition to showing a premixed area inside the flame zone of the stabilization region, temperature and concentration measurements indicated that jet flame attachment is sensitive to nozzle and flow conditions. The complex …

Diffusion, sub-diffusion, and escape: A study of over-damped Brownian motion
… with one-dimensional systems, we derive the diffusion coefficient for motion in a piecewise-defined potential where the barrier height of each section is taken from a probability distribution. When the distribution is exponential the usual transition between diffusion and sub-diffusion is …

Diffusion Processes with Reflection
… eine Partikelapproximation für die Wasserstein Diffusion bewiesen. Bei der Wasserstein Diffusion handelt es sich um einen reversiblen Markov Prozess mit Werten in der Menge von Wahrscheinlichkeitsmaßen auf dem Einheitsintervall. Das Ziel ist es, ein Partikelsystem zu definieren, so dass der …

DIFFUSION CONTROLLED VINYL POLYMERIZATION
… these changes are due to the influence of self-diffusion upon the termination reaction. This phenomenon is commonly referred to as the gel effect and in order to explain the polymerization behavior after the onset of the gel effect, the chain length dependence of the termination reaction should …

Essays on policy diffusion
This thesis consists of three essays on policy diffusion which looks at the conditional diffusion of policies based on domestic political factors. It attempts to shed light on how different domestic political factors affect policy diffusion among independent but interrelated actors such as …

Diffusion in heterogeneous networks
We create a program to simulate diffusion in random graphs. Specifically,we create a generalization of bootstrap percolation which incorporates any number of societies and an arbitrary weight matrix W. The code was created from the start to be as general as possible and to easily be modified with …

Studies of Surface Diffusion
… different topics, all concerned with surface diffusion are considered. First, the relationship between the diffusion coefficient D and the jump rate (GAMMA) is examined. It is shown that in analogy to alloy diffusion, the diffusivity is given by
