1. Segmentation Methods for Medical Image Analysis : Blood vessels, multi-scale filtering and level set methods
Abstract : Image segmentation is the problem of partitioning an image into meaningful parts, often consisting of an object and background. As an important part of many imaging applications, e.g. face recognition, tracking of moving cars and people etc, it is of general interest to design robust and fast segmentation algorithms.

2. On the Multi-Scale Nature of Ski-Snow Friction : Field Testing, Characterisation and Modelling of Cross-Country Ski Performance
Abstract : The goal of most endurance sports is to get from point A to B in the shortest time possible. Throughout the course, athletes need to overcome the resistive forces that are present in their specific sport. READ MORE

3. Novel Multi-Scale Modeling Framework for Structure and Transport in Complex Battery Electrolytes
Abstract : Affordable high energy rechargeable batteries are crucial for further electrification of the transport sector, which is necessary in order to contribute to limit our CO2 emissions to acceptable levels. While today’s lithium-ion batteries (LIBs) have indeed initiated the electrification of the transportation section successfully, electric vehicles are still expensive and typically have ranges limited to ca.

4. On mechanical characterization and multi-scale modeling of Lithium-ion batteries
Abstract : Over the last few decades, rechargeable lithium-ion batteries have been extensively used in portable instruments due to their high energy density and low self-discharge rate. Recently, lithium-ion batteries have emerged as the most promising candidate for electric vehicles and stationary energy storage. READ MORE

5. Multi-scale methods for wave propagation in heterogeneous media
Abstract : Multi-scale wave propagation problems are computationally costly to solve by traditional techniques because the smallest scales must be represented over a domain determined by the largest scales of the problem. We have developed new numerical methods for multi-scale wave propagation in the framework of heterogeneous multi-scale methods. READ MORE
