Bath SIAM-IMA Student Conference

1 March 2017

University of Bath Logo

The University of Bath SIAM and IMA student chapter will be hosting a local student conference on 1st March 2017.

All PhD students are welcome to attend, and we would like to invite applications to present either a short talk or a poster on the day. This one day meeting is a great opportunity to discuss your research with fellow PhD students, and to share your work via a talk or poster in a relaxed environment.

Both SIAM and the IMA promote the applications of mathematics, but we hope that a wide range of research will be represented. We welcome talks and posters on any areas of applied mathematics, computational mathematics and statistics, and any mathematics which has current or potential applications to industry.

If you have any questions about the conference, you're welcome to email the Bath SIAM-IMA Student Chapter Committee.

Registration

Registration is now closed.

All are welcome to attend any of the sessions on the day, but lunch and coffee will only be available for those who have registered before the deadline.

Abstracts

Invited Talks

Dr Philippe Blondel (Department of Physics, University of Bath)
Exploring the Oceans – Science for a Better World (pdf)

Oceans make up the largest part of the Earth, the "Blue Planet''. This talk will show, through recent research, how Physics (and Mathematics, of course) are used to explore the seven seas and help us move toward a better world. This will be illustrated with examples from recent field surveys by scientists from the University of Bath, including underwater noise pollution, the protection of marine mammals, tsunamis around Europe, de-risking marine renewable energies, and monitoring climate change and Arctic glaciers. Current scientific challenges will be presented, along with possible ways forward, all including a large dose of mathematics.

Prof. S. Jon Chapman (Mathematical Institute, University of Oxford)
Asymptotics Beyond All Orders: The Devil's Invention?

"Divergent series are the invention of the devil, and it is shameful to base on them any demonstration whatsoever." --- N. H. Abel.

The lecture will introduce the concept of an asymptotic series, showing how useful divergent series can be, despite Abel's reservations. We will then discuss Stokes' phenomenon, whereby the coefficients in the series appear to change discontinuously. We will show how understanding Stokes phenomenon is the key which allows us to determine the qualitative and quantitative behaviour of the solution in many practical problems. Examples will be drawn from the areas of surface waves on fluids, crystal growth, dislocation dynamics, localised pattern formation, and Hele-Shaw flow.​​

Using Real-World Data to Predict Response to High Cost Drugs in Rheumatology (pdf)

Over the last decade, the number and scope of new drugs available to treat rheumatoid arthritis has grown exponentially. Physicians now have a wide range of targeted drugs with proven efficacy in helping reduce the impact of this damaging disease, however, not all patients respond to all drugs. The British Society for Rheumatology Biologics Registry (BSRBR) was started 15 years ago to monitor the effects of these new drugs, and now follows the long-term outcomes of over 20,000 rheumatoid arthritis patients. My research uses real-world longitudinal drug response data from the BSRBR, with the aim of identifying the characteristics of patients with rheumatoid arthritis who are likely to respond to these drugs, to help to personalise medicine at an individual level.

Bounds on the Helmholtz Equation with Nontrapping Wavespeed (pdf)

Sound waves are used absolutely everywhere, from searching for oil underneath the sea to ultrasound scans during pregnancy. Therefore, it is important to be developing fast algorithms for the numerical solution of the PDEs lying behind sound wave propagation, and proving that these algorithms work.

One of the critical ingredients in proving that such algorithms work is obtaining bounds on the solution of the underlying PDE.

In this talk we'll introduce the Helmholtz equation, the simplest model of sound wave propagation, and consider certain situations in which we can obtain such bounds, and we'll provide some physical intuition as to why in other situations these bounds can never hold.

Emma Horton (Department of Mathematics, University of Bath)
An Introduction to the Neutron Transport Equation (pdf)

The neutron transport equation was originally used to study the kinetic theory of gases. However, it has been studied in much greater detail since the development of chain reacting nuclear reactors after WWII.

In this talk, we will introduce a basic form of the neutron transport equation and discuss its importance in the modelling of neutrons in nuclear reactors. We will then see an enhanced version of the neutron transport equation, which allows us to incorporate other particles, such as gamma rays and delayed neutrons, into our model.

Jehan Alswaihli (Department of Mathematics and Statistics, University of Reading)
Synergy of Data Assimilation and Inverse Problems Techniques (pdf)

The need to understand the neural field activity for realistic living systems is a current challenging task in neuroscience. The problem consists of two parts; firstly, for simulations we usually need to determine their constituents in particular systems. We provide an integral equation approach to the construction of the neural activity in the case where the neural activity is governed by a delay neural field equation. This problem is known as the inverse neural field problem. Secondly, for simulation of dynamical neural activity, we need to determine an appropriate initial state to start such simulation.

James Fidal (Department of Architecture & Civil Engineering, University of Bath)
Applications of Mathematics in Urban Rainfall-Runoff Modelling (pdf)

The introduction of urban land-cover changes the hydrological characteristics of catch- ments, and there is a need to develop hydrological models to account for these changes. This study presents a conceptual framework for explicitly accounting for effects of urban- isation on catchment rainfall-runoff characteristics. The framework consists of a number of parameter-parsimonious extension to an existing rainfall-runoff model to represent the urban effects on infiltration and river routing. The ability of the new urban model to explain the urban effects was assessed by comparing the default (non-urban) model with the new urban model using hydrological data from 29 urban catchments in the Thames catchment. Model performance was assessed based on a range of model performance criteria and a jackknife in order to test for statistical significance between model per- formance. Results suggest that the new model including the urban extensions can add explanatory power in urbanised catchments.

James Jackamann (Department of Mathematics & Statistics, University of Reading)
Discontinuous Galerkin Methods for Nonlinear Wave Interactions (pdf)

We introduce a methodology of discretising (bi-)Hamiltonian PDEs via discontinuous finite element methods focusing primarily on the non-linear wave equation KdV as an illustrative example. The resultant methods are of arbitrary order in space and have desirable properties including conservation of the relevant Hamiltonians.

Arriving by train

If you are arriving by train, you should arrive at Bath Spa train stations. You can then take the U1, 17 or 18 bus to the university from Dorchester Street (opposite the station to the left), or walk to the university in 30-40 minutes (up quite a steep hill!).

Arriving into Bristol Airport

Coming from Bristol airport, take the A4 bus to Bath, which brings you to the train station, from where you can walk or take a bus, as described above.

Arriving by car

If you plan to drive to the university, limited visitor parking spaces are available on campus. See the university's guide to parking on campus.
