1. Multidrug-Resistant Escherichia coli and Klebsiella pneumoniae : Treatment, Selection and International Spread
Sammanfattning : The prevalence of Escherichia coli and Klebsiella pneumoniae producing extended-spectrum beta-lactamases (ESBLs) and carbapenemases is increasing worldwide. Therapeutic options for infections with these bacteria are limited not only by the production of ESBLs and carbapenemases, which confer resistance to cephalosporins and carbapenems, but also by frequent co-resistance to other antibiotics.

2. A Probabilistic Model for Positional Voting - Spectrum Games -
Sammanfattning : This thesis considers a class of cooperative n-person games (voting games) in which the voters are spread across an ideological scale. The two most commonly used measures of individual voting power in voting games are the Shapley-Shubik index and the Banzhaf-Coleman index. In both indices, the actors are assumed anomymous and treatad symmetrically. LÄS MER
3. Spectrum Sensing for Dynamic Spectrum Access in Cognitive Radio
Sammanfattning : Abstract. The number of mobile devices is constantly growing, and the exclusivestatic spectrum allocation approach is leading to the spectrum scarcity problem whensome of the licensed bands are heavily occupied and others are nearly unused.Spectrum sharing and opportunistic spectrum access allow achieving more efficientspectrum utilization.
