1. Towards a new sensing strategy for measuring paper pulp properties : a combination of ultrasonic and optical measurement techniques
Abstract : In the manufacturing process of paper the mass fraction and material properties of the fibres in the pulp suspension are important for the strength and quality of the finished product. The properties of the fibres in the pulp suspension that enters the paper machine is not well understood and therefore an adequate prediction of the strength and quality of the finished paper is not possible.

2. Online characterization of wood pulp : foundations for a photoacoustic sensing technique
Abstract : Today, there is an increasing demand in the paper industry for better utilisation of the raw material and improved energy efficiency. Also, the increasing use of recycled paper in the manufacturing process leads to a situation where the knowledge of pulp properties needs to be improved and controlled. READ MORE

3. Biochemical and spectral characterization of micro- and macroalgae
Abstract : Algae contain many compounds which are of interest to the pharmaceutical, agricultural and food industries, among others. Despite the potential for many applications, a quick, accurate and inexpensive method for characterising algae is lacking. READ MORE

4. Bending, Twisting and Turning : Protein Modeling and Visualization from a Gauge-Invariance Viewpoint
Abstract : Proteins in nature fold to one dominant native structure. Despite being a heavily studied field, predicting the native structure from the amino acid sequence and modeling the folding process can still be considered unsolved problems. In this thesis I present a new approach to this problem with methods borrowed from theoretical physics. READ MORE
