6. Finite element analysis of thin-walled structures subjected to impact loading
Sammanfattning : This thesis is devoted to the numerical solution of dynamic problems involving thin-walled structures. Special consideration is paid to the effects of contact-impacts. LÄS MER
7. Stability and Receptivity of Three-Dimensional Boundary Layers
Sammanfattning : The stability and the receptivity of three-dimensional flat plate boundary layers is studied employing parabolised stability equations. These allow for computationally efficient parametric studies. Two different sets of equations are used. LÄS MER
8. A new non-linear GARCH model
Sammanfattning : This dissertation contains four papers in the field of financial econometrics. In the first paper, A Smooth Transition ARCH Model for Asset Returns, a new class of ARCH models is introduced. The model class allows for non-linearity in the equation for the conditional variance.

9. A study of wireless communications with reinforcement learning
Sammanfattning : The explosive proliferation of mobile users and wireless data traffic in recent years pose imminent challenges upon wireless system design. The trendfor wireless communications becoming more complicated, decentralized andintelligent is inevitable. LÄS MER
10. Four essays on the econometric modelling of volatility and durations
Sammanfattning : The thesis "Four Essays on the Econometric Modelling of Volatility and Durations" consists of four research papers in the area of financial econometrics on topics of the modelling of financial market volatility and the econometrics of ultra-high-frequency data. The aim of the thesis is to develop new econometric methods for modelling and hypothesis testing in these areas. LÄS MER
