2. Large eddy simulation of cavitating and non-cavitating flow
Abstract : Most marine configurations are subject to a number of complex and important hydrodynamic phenomena affecting the overall performance of the vessel, both regarding resistance and propulsive efficiency. In this thesis, the possibility of numerically simulating some of these phenomena is investigated. READ MORE

3. Large-Eddy Simulation for Computing the Flow Around Vehicles
Abstract : The feasibility of the use of large-eddy simulation (LES) in external vehicle aerodynamics is investigated. The computational requirement for LES of the full size car at road conditions is beyond the capability of computers in the near future. Since LES cannot be used for quantitative prediction of this flow, i.e. READ MORE

5. On Concurrent Error Detection and Error Propagation
Abstract : This thesis addresses three important steps in the selection of error detection mechanisms for microprocessors: (i) the design and evaluation of error detection mechanisms, (ii) the study of microprocessor error behavior and propagation and (iii) the design and use of error models. The first part of the thesis evaluates four error detection methods with respect to para- meters such as error detection coverage and performance loss, while the second and third parts focus on determining the error patterns most likely to occur in a computer system when different types of faults are present and how to incorporate those error patterns into error models.
