16. Preparations for the next solar WIMP Analysis with IceCube : Advances in simulation, filtering, event topology identification and analysis approach
Sammanfattning : In the year 2011 the construction of IceCube, a neutrino observatory buried in deep clear Antarctic ice, was completed. IceCube now consists of an array of 5160 digital light detection modules assembled on 86 strings, which encloses a instrumented volume of roughly 1~km$^3$ optimized for detection of neutrinos down to energies of 100~GeV.

17. Estimation and detection of transmission line characteristics in the copper access network
Sammanfattning : The copper access-network operators face the challenge of developing and maintaining cost-effective digital subscriber line (DSL) services that are competitive to other broadband access technologies. The way forward is dictated by the demand of ever increasing data rates on the twisted-pair copper lines. LÄS MER
18. Fungal taxonomy and systematics in the digital era, with an outlook on the cantharelloid clade (Basidiomycota)
Sammanfattning : Fungi form a large and ubiquitous group of organisms where species identification and delimitation on morphological grounds often fall short. DNA sequences have proved an invaluable information source for these pursuits and are now routinely used in most mycological laboratories. LÄS MER
19. Development of New Methods for Inferring and Evaluating Phylogenetic Trees
Sammanfattning : Inferring phylogeny is a difficult computational problem. Heuristics are necessary to minimize the time spent evaluating non optimal trees. In paper I, we developed an approach for heuristic searching, using a genetic algorithm. Genetic algorithms mimic the natural selections ability to solve complex problems. LÄS MER
20. Interaction Between Antimicrobial Peptides and Phospholipid Membranes : Effects of Peptide Length and Composition
Sammanfattning : Due to increasing problems with bacterial resistance development, there is a growing need for identifying new types of antibiotics. Antimicrobial peptides constitute an interesting group of substances for this purpose, since they are believed to act mainly by disrupting the bacterial membrane, which is a fast and non-specific mechanism.
