1. Finding fitness : empirical and theoretical explorations of inferring fitness effects from population-level SNP data
Sammanfattning : The distribution of fitness effects (DFE) describes the likelihood that a new mutation has a specific effect on the fitness of an individual in a given population. The shape of the DFE is a result of several factors such as population size, mating system and selective environment, and can in turn influence the evolutionary potential of a species. LÄS MER
2. 3D Time-lapse Analysis of Seismic Reflection Data to Characterize the Reservoir at the Ketzin CO2 Storage Pilot Site
Sammanfattning : 3D time-lapse seismics, also known as 4D seismics, have great potential for monitoring the migration of CO2 at underground storage sites. This thesis focuses on time-lapse analysis of 3D seismic reflection data acquired at the Ketzin CO2 geological storage site in order to improve understanding of the reservoir and how CO2 migrates within it.

3. Genetic variation in natural populations: a modeller's perspective
Sammanfattning : Thanks to advances in genome sequencing, empirical patterns of within- and between-species genetic variation are readily available. By studying these patterns much has been learned about the evolutionary histories of species. But the causes and consequences of different evolutionary histories are still difficult to tell apart.

4. Seismic Investigations at the Ketzin CO2 Injection Site, Germany: Applications to Subsurface Feature Mapping and CO2 Seismic Response Modeling
Sammanfattning : 3D seismic data are widely used for many different purposes. Despite different objectives, a common goal in almost all 3D seismic programs is to attain better understanding of the subsurface features. LÄS MER
5. Local structure and dynamics in proton conducting perovskite oxides: insights from quasielastic neutron scattering and infrared spectroscopy
Sammanfattning : Proton conducting oxides have been extensively studied in the past decade due to their potential application in a number of energy related devices such as solid oxide fuel cells, hydrogen sensors, and steam electrolyzers. However, the final industrialisation of these materials depends on unlocking fundamental questions about the relationship between their atomic structure, localized proton dynamics and proton conductivity.
