6. 100 million years of shark macroevolution : A morphometric dive into tooth shape diversity
Sammanfattning : Few vertebrate clades exhibit the evolutionary longevity and versatility of sharks, which constitute nearly half of all current chondrichthyan biodiversity and represent an ecological diversity of mid-to-apex trophic-level predators in both marine and freshwater environments. The rich fossil record of shark teeth from Mesozoic and Cenozoic rocks also makes the group amenable to large-scale quantitative analyses. LÄS MER
7. Large deviations for weighted empirical measures and processes arising in importance sampling
Sammanfattning : This thesis consists of two papers related to large deviation results associated with importance sampling algorithms. As the need for efficient computational methods increases, so does the need for theoretical analysis of simulation algorithms. This thesis is mainly concerned with algorithms using importance sampling. LÄS MER
8. On large deviations and design of efficient importance sampling algorithms
Sammanfattning : This thesis consists of four papers, presented in Chapters 2-5, on the topics large deviations and stochastic simulation, particularly importance sampling. The four papers make theoretical contributions to the development of a new approach for analyzing efficiency of importance sampling algorithms by means of large deviation theory, and to the design of efficient algorithms using the subsolution approach developed by Dupuis and Wang (2007).

9. A social semiotic account of music-movement correspondences
Sammanfattning : In this thesis, I develop a comprehensive account of synergies between music and movement from a social semiotic perspective. This account includes an analytical framework, a cross-contextual case study and an assessment of the expansive scope of the social semiotic framework. LÄS MER
10. Macroeconometric Studies of Private Consumption, Government Debt and Real Exchange Rates
Sammanfattning : Advances in time series analysis during the last two decades have stimulated research in a number of areas in macroeconomics. This thesis is a compilation of five essays using cointegrated vector autoregressive (VAR) models, unit root tests and regime switching models to investigate the behavior of private consumption, public debt and the real exchange rate.
