1. Discrete Scale-Space Theory and the Scale-Space Primal Sketch
Abstract : This thesis, within the subfield of computer science known as computer vision, deals with the use of scale-space analysis in early low-level processing of visual information. The main contributions comprise the following five subjects:The formulation of a scale-space theory for discrete signals. READ MORE

2. Numerical simulation of multi-scale transport processes and reactions in pem fuel cells using two-phase models
Abstract : A numerical study for the cathode of a PEM fuel cell has been performed in this study. The results have been limited to cathode only because, in PEM fuel cells, the oxygen reduction reactions, ORRs, are considered the rate limiting reactions and govern the fuel cell performance.

3. Multi-Scale Surface Water-Groundwater Interaction : Implications for GroundwaterDischarge Patterns
Abstract : Rivers and aquifers are continuously exchanging water, driven by processes that occur on various temporal and spatial scales, ranging from small streambed features to large geological structures. The interaction between these two components occurs in permeable sediments below the stream channel, called the hyporheic zone. READ MORE

4. 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

5. 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. READ MORE
