1. Capabilities of Convolutional Codes: Unequal Error Protection and More
Sammanfattning : Many communication systems obtain enhanced performance by using concatenated coding schemes. Turbo codes and woven convolutional codes are two examples of such schemes. LÄS MER
2. Dynamics of the Bacterial Genome : Rates and Mechanisms of Mutation
Sammanfattning : Bacterial chromosomes are highly dynamic, continuously changing with respect to gene content and size via a number of processes, including deletions that result in gene loss. How deletions form and at what rates has been the focus of this thesis. In paper II we investigated how chromosomal location affects chromosomal deletion rates in S. LÄS MER
3. Topics in Simulation and Stochastic Analysis
Sammanfattning : Paper A investigates how to simulate a differentiated mean in cases where interchanging differentiation and expectation is not allowed. Three approaches are available, finite differences (FD's), infinitesimal perturbation analysis (IPA) and the likelihood ratio score function (LRSF) method. LÄS MER
4. Macroeconomic Studies on Fiscal Policy and Real Exchange Rates
Sammanfattning : This thesis contains four empirical macroeconomic studies and the papers may briefly be summarized as follows. In the first paper, we use both descriptive statistics and regression analysis to investigate whether movements in real exchange rates and money supply before and during fiscal contractions matter for the macroeconomic outcome.

5. Mathematical Models of Molecular Evolution
Sammanfattning : This thesis deals with mathematical models of Darwinian evolution in populations of simple living organisms. We study models which describe how the representation of different gene sequences in the population is affected by the fundamental forces of evolutionary processes, such as selection pressure, the mutation rate and the time dynamics of the underlying fitness landscape.
