The seminar will focus on mathematical modelling of physics phenomena,
with applications in e.g. mass and heat transfer, fluid flow, and
electromagnetic wave propagation. Simultaneous solutions of several
physics phenomena described by PDEs - multiphysics - will also be
presented and discussed.
All models will be realised through the use of the MATLAB based finite element package FEMLAB. FEMLAB is a multiphysics modelling environment with built-in PDE solvers for linear, non-linear, time dependent and eigenvalue problems. For ease-of-use, it comprises ready-to-use applications for various physics phenomena, and tailored applications for Structural Mechanics, Electromagnetics, and Chemical Engineering. But in addition, FEMLAB facilitates straightforward implementation of arbitrary coupled non-linear PDEs, which brings about a great deal of flexibility in problem definition. Please see http://ww.uk.comsol.com for more info. FEMLAB is developed by the COMSOL Group, a Swedish headquartered spin-off from the Royal Institute of Technology (KTH) in Stockholm, with offices around the world. Its UK office is situated in The Oxford Science Park. |

| We will discuss the mixing rate of the standard random walk on the giant component of the random graph G(n,p). We tie down the mixing rate precisely for all values of p greater than (1+c)/n for any positive constant c. We need to develop a new bound on the mixing time of general Markov chains, inspired by and extending work of Kannan and Lovasz. This is joint work with Nick Fountoulakis. | |||

| We consider an investment model that can operate in two different modes. The transition from one mode to the other one is immediate and forms a sequence of costly decisions made by the investment's management. Each of the two modes is associated with a rate of payoff that is a function of a state process which can be an economic indicator such as the price of a given comodity. We model the state process by a general one-dimensional diffusion. The objective of the problem is to determine the switching strategy that maximises a long-term average criterion in a pathwise sense. Our analysis results in analytic solutions that can easily be computed, and exhibit qualitatively different optimal behaviours. | |||
