1. Singular Fluxes in Ten and Eleven Dimensions : Sources, Singularities, Fluxes and Spam
Abstract : The energy content of our present universe is dominated by the dark-energy, or vacuum energy, which provides accelerated cosmic expansion. Dark energy has a possible effective explanation through a positive cosmological constant. READ MORE

2. Combining analytical and iterative reconstruction in helical cone-beam CT
Abstract : Contemporary algorithms employed for reconstruction of 3D volumes from helical cone beam projections are so called non-exact algorithms. This means that the reconstructed volumes contain artifacts irrespective of the detector resolution and number of projection angles employed in the process. READ MORE

3. Constructive cooperative coevolution for optimising interacting production stations
Abstract : Engineering problems have characteristics such as a large number of variables, non-linear, computationally expensive, complex and black-box (i.e. unknown internal structure). These characteristics prompt difficulties for existing optimisation techniques. READ MORE

4. Analysis of Acrylamide and Anthocyanins in Foods : Extraction Optimization for Challenging Analytes
Abstract : In this thesis, the main concern has been to improve the reliability of different parts of the analytical workflow (Paper I, II, IV &V). Additionally, one of the resulting optimized methods was used in a real application (Paper III). Paper I-II concerned the extraction of acrylamide (AA) from foods. READ MORE
