1. Input Calibration, Code Validation and Surrogate Model Development for Analysis of Two-phase Circulation Instability and Core Relocation Phenomena
Abstract : Code validation and uncertainty quantification are important tasks in nuclear reactor safety analysis. Code users have to deal with large number of uncertain parameters, complex multi-physics, multi-dimensional and multi-scale phenomena. READ MORE

2. Design and Optimization under Uncertainties : A Simulation and Surrogate Model Based Approach
Abstract : This thesis deals with development of complex products via modeling and simulation, and especially the use of surrogate models to decrease the computational efforts when probabilistic optimizations are performed. Many methods that can be used to perform probabilistic optimizations exist and this thesis strives to present and demonstrate the capabilities of a few of them. READ MORE

3. Efficient Optimization of Complex Products : A Simulation and Surrogate Model Based Approach
Abstract : This thesis investigates how to use optimization efficiently when complex products are developed. Modelling and simulation are necessary to enable optimization of products, but here it is assumed that verified and validated models of the products and their subsystems are available for the optimization.

4. A trust-privacy model of customers' willingness to be profiled and to transact online : theoretical model and empirical estimation
Abstract : Privacy concerns are cited to be on the rise due to intense personalization efforts by online firms. Alongside, trust placed in stores has been identified as a key component behind consumer willingness to transact online. READ MORE

5. Mathematical modelling for optimization of truck tyres selection
Abstract : This thesis, which consists of an introduction and three appended papers, concerns the optimal selection of tyres for a given vehicle configuration and an operating environment in which the vehicle is to be used. The optimization problem stems from an industrial project performed in cooperation between Chalmers University of Technology and Volvo Group Trucks Technology (GTT). READ MORE
