CARMA Research Group

Mathematical Modelling and Industrial Applications

About us

Leader: Mike Meylan

The mathematical modelling and industrial applications group works on the application of mathematics to solving real-world problems. We have particular expertise in the implementation of differential equations to modelling complex problems in fluid dynamics and other processes. Our research can be broadly grouped into the following areas.

1) Mathematical Modelling. We have wide-ranging experience in modelling including extensive applications in fluid flows, wave scattering, material science, and biological processes including interactions between cells and swarming of insects.

2) Nanostructures and their applications in nanotechnology, includeing modelling electrorheologicalfluids, the mechanics of carbon nanostructures, nanomaterials used in biology and medicine and protein and other polymer chain structures using the calculus of variations.

3) Electromaterials in energy applications such as solar cells, energy storage and carbon capture.

4) Finite element methods and numerical solution of complex equations, including Mixed and Hybrid Finite Element Methods, Domain Decomposition Methods, Non-conforming Discretization Techniques, Nearly Incompressible Elasticity, Approximation Theory, Subset Selection & Variational Methods in Image Processing. The group also specialises in computaional techniques such as Dissipative Particle Dynamics (DPD), Molecular Dynamics (MD) and Smoothed Particle Hydrodynamics (SPH) which are used to model a complex system involving micro and nano materials.

Our group also focuses on working with industry to develop mathematical models to solve real industrial-based problems. The major upcoming event for our group is the Mathematics in Industry Study Group (MISG) for 2020-2022.

    "First principles molecular dynamics: a tool to study materials at the atomic scale"
       Dr Carlo Massobrio
    This talk will focus on the basic concepts of first-principles molecular dynamics (FPMD) and on some related applications developed within our team at IPCMS in Strasbourg. We are interested in achieving quantitative predictions for materials at the atomic scale by relying on models based on an appropriate account of chemical bonding. This scheme allows for the production of temporal trajectories ensuring the connection between statistical mechanics and macroscopic properties. FPMD lies at the crossroad between molecular dynamics and density functional theory, this latter playing the role of potential energy depending on both the atomic and electronic structure of the system. Examples will be provided for several areas within computational materials science, with special emphasis on disordered materials.

    "From single cells to insect swarms: Non-local Advection for some problems in Biology"
        Fillipe Georgiou
    Classic modelling of biological systems assumes the length scale of interaction is far less than the modelling length scale. However, biological interactions can occur over long ranges via mechanisms such as sight and smell. It is possible to capture these interactions using classic conservation laws with a non-local velocity term. In this talk I will present various applications of non-local modelling from the modelling of phagocytosis at a single cell level up to the swarming behaviour of locusts. I will also look at various analysis and simulation techniques needed to approach these problems. Finally, I will present future goals and direction for my work.

    "Optimization Methods for Inverse Problems from Imaging"
       Prof Ke Chen
    Optimization is often viewed as an active and yet mature research field. However the recent and rapid development in the emerging field of Imaging Sciences has provided a very rich source of new problems as well as big challenges for optimization. Such problems having typically non-smooth and non-convex functionals demand urgent and major improvements on traditional solution methods suitable for convex and differentiable functionals.

    This talk presents a limited review of a set of Imaging Models which are investigated by the Liverpool group as well as other groups, out of the huge literature of related works. We start with image restoration models regularised by the total variation and high order regularizers. We then show some results from image registration to align a pair of images which may be in single-modality or multimodality with the latter very much non-trivial. Next we review the variational models for image segmentation. Finally we show some recent attempts to extend our image registration models from more traditional optimization to the Deep Learning framework.
