1. Some Extensions of Fractional Ornstein-Uhlenbeck Model : Arbitrage and Other Applications
Sammanfattning : This doctoral thesis endeavors to extend probability and statistical models using stochastic differential equations. The described models capture essential features from data that are not explained by classical diffusion models driven by Brownian motion.New results obtained by the author are presented in five articles.

2. Testing for Periodicity and Trend in Long-Memory Processes
Sammanfattning : This thesis presents methods of testing the periodicity and trend for the time series, which exhibit dependence over long periods of time. Many such processes can be modeled by a class of models called fractionally differenced processes. LÄS MER
3. Zeolite Membranes for Production of Biofuels
Sammanfattning : To deal with the increasing demand of renewable fuels, more efficient processes for the production of biofuels are needed. Zeolite membranes have the potential to improve many existing processes that could be used for production of biofuels. Methanol is a potential biofuel that may be produced from synthesis gas in an equilibrium limited reaction. LÄS MER
4. Early life exposures and lung function development
Sammanfattning : BACKGROUND: Lung development is a dynamic process, vulnerable to adverse environmental exposures. Starting in utero, development continues postnatally, and although lung structure is mainly set at around two years of age, the maturation process continues into young adulthood. LÄS MER
5. Numerical solutions to non-linear inhomogeneous problems in Superconductivity : From sphalerons to multi-band boundary states and spontaneous magnetic fields
Sammanfattning : This thesis is a compilation of theoretical works focused on simulating and studying open questions regarding single and multiband superconductivity. In the last decades, with the discovery of multiband superconductors, the spectrum of potential applications has greatly widened. LÄS MER
