6. A Differentiable Approach to Stochastic Differential Equations : the Smoluchowski Limit Revisited
Sammanfattning : In this thesis we generalize results by Smoluchowski [43], Chandrasekhar[6], Kramers, and Nelson [30]. Their aim is to construct Brownian motion as a limit of stochastic processes with differentiable sample paths by exploiting a scaling limit which is a particular type of averaging studied by Papanicolao [35].

7. A Parametric Approach to Yeast Growth Curve Estimation and Standardization
Sammanfattning : The purpose of this thesis is to contribute to the understanding of yeast growth. It builds upon a dataset consisting of growth curves of 576 Saccharomyces cerevisiae mutants in eight different environments. The data will be a part of a publicly available phenotypic library, PROPHECY, containing growth curves and characteristics of viable S. LÄS MER
8. Predator responses to non-stationary rodent cycles
Sammanfattning : Regular fluctuations in population size, cycles, are common in small mammals and have important effects on predator populations and life histories. In this thesis, I identify long-term patterns and processes in two specialist predators, the arctic fox Vulpes lagopus and the rough-legged buzzard Buteo lagopus, in relation to their prey (lemmings and voles) and in the case of the arctic fox also to a dominant competitor, the red fox Vulpes vulpes.

9. How Does it Feel and How is it measured? Assessing Sitting Comfort and Postures of Rear-Seated Car Passengers in Stationary and Driven Scenarios Over Time
Sammanfattning : This licentiate thesis presents the results of an empirical study focused on examining the comparative effectiveness of short stationary studies versus long driving studies in evaluating sitting postures, belt fit, and sitting comfort in cars. The study employed a mixed-methods approach, in which 19 participants experienced two different test scenarios in the rear seat of a car: a stationary scenario within an indoor garage and a driven scenario on a predefined route in regular traffic, each lasting 45 minutes.

10. Reconstruction of a stationary flow from boundary data
Sammanfattning : We study a Cauchy problem arising in uid mechanics, involving the socalled stationary generalized Stokes system, where one should recover the ow from boundary measurements. The problem is ill-posed in the sense that the solution does not depend continuously on data.Two iterative procedures for solving this problem are proposed and investigated. LÄS MER
