1. Approaching well-founded comprehensive nuclear data uncertainties : Fitting imperfect models to imperfect data
Abstract : Nuclear physics has a wide range of applications; e.g., low-carbon energy production, medical treatments, and non-proliferation of nuclear weapons. Nuclear data (ND) constitute necessary input to computations needed within all these applications. READ MORE

2. The Diversity and Unity of Reactor Noise Theory
Abstract : The study of reactor noise theory concerns questions about cause and effect relationships, and the utilisation of random noise in nuclear reactor systems. The diversity of reactor noise theory arises from the variety of noise sources, the various mathematical treatments applied and the various practical purposes. READ MORE

3. Models and Methods for Random Fields in Spatial Statistics with Computational Efficiency from Markov Properties
Abstract : The focus of this work is on the development of new random field models and methods suitable for the analysis of large environmental data sets. A large part is devoted to a number of extensions to the newly proposed Stochastic Partial Differential Equation (SPDE) approach for representing Gaussian fields using Gaussian Markov Random Fields (GMRFs).

4. Some Contributions to Description and Validation of the Extreme Value Distribution
Abstract : This thesis focuses on the validation and description of the Gumbel distribution. Since this is a scale and location parameter distribution, the generalized least squares regression of the order statistics on the expected values can be used, without the necessity of iteration, to obtain the best linear unbiased estimates of the parameters.

5. Genetic variance and covariance components for across population evaluation of Brown Swiss cattle
Abstract : Dairy cattle breeding is an international business, with trade of animal material across populations. Interbull performs international genetic evaluations of dairy bulls, enabling fair comparisons across populations. READ MORE
