1. Enzymatic metal-chelation by porphyrins
Abstract : This thesis deals with the structure and function of two different enzymes, ferrochelatase and magnesium chelatase, that catalyse similar reactions. When this work started, a three-dimensional model of ferrochelatase existed. Much was known about the enzyme, but some details remained unclear. READ MORE

2. Increasing the storage capacity of Recursive Auto-associative Memory by segmenting data
Abstract : Recursive Auto-associative Memory (RAAM) has been proposed as a connectionist solution for all structured representations. However, it fails to scale up to representing long sequences of data. In order to overcome this, a number of different architectures and representations have been proposed. READ MORE

3. A Modular Tool Architecture for Worst-Case Execution Time Analysis
Abstract : Estimations of the Worst-Case Execution Time (WCET) are required in providing guarantees for timing of programs used in computer controlled products and other real-time computer systems. To derive program WCET estimates, both the properties of the software and the hardware must be considered. READ MORE

4. Morphology and material stability in polymer solar cells
Abstract : Polymer solar cells are promising in that they are inexpensive to produce, and due to their mechanical flexibility have the potential for use in applications not possible for more traditional types of solar cells. The performance of polymer solar cells depends strongly on the distribution of electron donor and acceptor material in the active layer. READ MORE

5. Materials and Device Engineering for Efficient and Stable Polymer Solar Cells
Abstract : Polymer solar cells form a promising technology for converting sunlight into electricity, and have reached record efficiencies over 10% and lifetimes of several years. The performance of polymer solar cells depends strongly on the distribution of electron donor and acceptor materials in the active layer. READ MORE
