Moving Unstructured Mesh Methods

Simulation of moving physical interfaces in 3-D is complicated by the need to (1) resolve complex realistic geometries with a spatial discretization, (2) accurately compute evolving physical fields on the discretization, and (3) evolve the di   more››

Modelling the Endothelial Cell Response to Fluid Flow

Following the onset of shear stress due to fluid flow endothelial cells polarise and elongate in the direction of flow. How the mechanical signal is transformed into an organised and directed response is poorly understood. A multi-scale cellular P   more››

An extension to the Brun-Titchmarsh theorem

The Siegel-Walfisz theorem states that for any B>0, we have Sp=x, p?d (mod v) 1 ~ x/f(v) log(x) for v = logB(x) and (v,d)=1. This only gives an asymptotic formula for the number of primes in an arithmetic progression for quite a small modulus v co   more››

Manin conjectures for K3 surfaces

The Manin conjectures describe for geometrically easy varieties how the number of their rational points of bounded height should grow as the height bound varies. In this talk I will describe recent computations that suggest a similar statement for   more››

When optimization becomes irrelevant: time-inconsistency and its consequences

In optimal control, one traditionally discounts the future at a constant rate: a gain u occurring at time t>0 is valued today at u exp(-rt), where r is the discount rate. If non-constant discount rates are used, as they should   more››

Root numbers and Selmer groups of elliptic curves

The theory of root numbers predicts when elliptic curves over number fields have rational points of infinite order. In this talk, we shall discuss results which bring together the root numbers and non-commutative Iwasawa theory. It is joint work with   more››

Elliptic Nets

Elliptic divisibility sequences are integer recurrence sequences, each of which is associated to an elliptic curve over the rationals together with a rational point on that curve. I'll give the background on these and present a higher-dimensional ana   more››

Financial Hedging of Operational Flexibility

We extend the framework of real options to value the compound timing option owned by a manager of an industrial asset. The operator has control over the production modes, but faces operational constraints which introduce path-dependency. Moreover,   more››

Isogeometric Analysis

The purpose of this talk is to explore the new generation of computational mechanics procedures based on modern developments in computational geometry. The emphasis will be on the Isogeometric approach in which basis functions generated from NURBS   more››

Monitoring the health of Queensland's rivers: steps to designing an optimal spatial sampling scheme

Spatial sampling design is a key step in developing an optimal large-scale, multi-objective aquatic monitoring program. Aquatic systems can be complex and irregular, thus it is critical to ensure that a spatial design is statistically valid, imple   more››
