1. The fW-mean filter framework for topology optimization and analysis of Friedrichs systems
Abstract : Part I. Topology optimization is the most general form of design optimization in which the optimal layout of material within a given region of space is to be determined. Filters are essential components of many successful density based topology optimization approaches. READ MORE

3. Variational Problems and Level Set Methods in Computer Vision - Theory and Applications
Abstract : Current state of the art suggests the use of variational formulations for solving a variety of computer vision problems. This thesis deals with such variational problems which often include the optimization of curves and surfaces. READ MORE

4. On computational modeling of sintering based on homogenization
Abstract : Liquid-phase sintering is the process where a precompacted powder, “green body”, is heatedto the point where (a part of) the solid material melts, and the specimen shrinks while keeping(almost) net shape. In the case of hardmetal, the microstructure is defined by WC-Co-particleswith large pores, whereby molten Co represents the liquid phase. READ MORE

5. Statistical Segmentation and Registration of Medical Ultrasound Data
Abstract : The interpretation of ultrasonic imagery is typically not straightforward and of quite subjective nature and therefore strongly dependent on the expertise of its users. Thus the development of algorithms which aid in the interpretation of ultrasonic data is a highly relevant topic. READ MORE
