Structure Theorems in Graph Theory

Fix a graph H. What is the most general graph that does not contain H? In other words, how do we explicitly construct all the graphs that do not contain H? To begin to make this precise, we have to say what 'contain' means;; we have more››

A unified approach to modelling trajectories

The talk will concern the employment of stochastic gradient systems in the modeling and statistical analysis of biological and ecological processes of moving particles. The work is stimulated by scientific questions and data sets of the movements more››

Data Stream Processing with Resource Adaptive Computation

The problem of streaming data has gained importance in recent years because of advances in hardware technology. The ubiquitous presence of data streams in a number of practical domains has generated a lot of research in this area. Example applicat more››

Modelling biofilm growth in a porous medium with application in bioremediation

Studies on bioremediation in a porous medium have mainly focused on wastewater treatment. The interest in these investigations has focused on optimising degradation rates and substrate loading. Pore clogging has not been studied thoroughly. When p more››

Sequential Experiment Design for Contour Estimation from Computer Simulators

In many engineering applications, one is interested in identifying the inputs to a computer simulator that lead to a pre-specified output. In this talk we introduce statistical methodology that identifies the desired contour in the input space. Th more››

A Simple Technique for Solving Partial Differential Equations on Surfaces

Many applications require the solution of time dependent partial differential equations (PDEs) on surfaces or more general manifolds. Methods for treating such problems include surface parameterization, methods on triangulated surfaces and embeddi more››

Mechanistic Images in Geometric Form: Heinrich Hertz's Principles of Mechanic

During the last three years of his life Heinrich Hertz wrote a treatise on mechanics which was to be the last attempt to supply a satisfactory foundation to classical mechanics. It was published posthumously in 1894, the year of his death. more››

Feasible Proofs and Computations

The concepts of proof and computation are central to virtually any intellectual human activity. However, before the remarkable advances of the 20th century mathematical logic, the border between them had never been sharp even in the context of pur more››

Glacier and ice sheet dynamics

Glaciers and ice sheets are thin viscous gravity currents subject to mass sources and sinks due to surface snow accumulation and melting. Mathematically, the evolution of glacier geometry poses interesting free boundary problems. Land-based glaciers more››
