6. A weak space-time formulation for the linear stochastic heat equation
Sammanfattning : The topic covered in this thesis is the introduction of a new formulation for the linear stochastic heat equation driven by additive noise, based on the space-time variational formulation for its deterministic counterpart. Having a variational formulation allows the use of the so called inf-sup theory in order to obtain results of existence and uniqueness in a relatively simple way. LÄS MER
7. Necessary Optimality Conditions for Two Stochastic Control Problems
Sammanfattning : This thesis consists of two papers concerning necessary conditions in stochastic control problems. In the first paper, we study the problem of controlling a linear stochastic differential equation (SDE) where the coefficients are random and not necessarily bounded. We consider relaxed control processes, i.e. LÄS MER

9. Thermal adaptation along a latitudinal gradient in damselflies
Sammanfattning : Understanding how temperature affects biological systems is a central question in ecology and evolutionary biology. Anthropogenic climate change adds urgency to this topic, as the demise or success of species under climate change is expected to depend on how temperature affects important aspects of organismal performance, such as growth, development, survival and reproduction.

10. Prosodic Phrasing in Spontaneous Swedish
Sammanfattning : One of the most important functions of prosody is to divide the flow of speech into chunks. The chunking, or prosodic phrasing, of speech plays an important role in both the production and perception of speech. LÄS MER
