  1. 11. Relation Between Drug Exposure and Selection of Antibiotic Resistant Bacteria

    Författare :Sara K. Olofsson; Otto Cars; Dan I. Andersson; Diarmaid Hughes; George G. Zhanel; Uppsala universitet; []
    Nyckelord :Microbiology; Pharmacokinetics; Pharmacodynamics; Antibiotic resistance; Selection; Transmission; Mathematical model; Escherichia coli; Mikrobiologi;

    Sammanfattning : The worldwide increase in antibiotic resistance is a concern for public health. When the appropriate antibiotic dosage is determined, the priorities are efficacy and toxicity. The aim of this thesis was to gain knowledge about the most efficient dosing regimens in order to minimize the emergence and selection of antibiotic-resistant mutants. LÄS MER

  4. 13. Polarization-Mode Disperion in Optical Fibers: Characterization, Transmission Impairments, and Compensation

    Författare :Henrik Sunnerud; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optical fibers; polarization mode dispersion PMD ; ultra high bit rates; PMD compensation; measurement of distributed PMD; digital signal transmission;

    Sammanfattning : The topic of this thesis is polarization-mode dispersion (PMD) in optical fibers and its impact on high-speed data transmission. The work can be divided into three parts which deal with the major aspects of PMD: characterization, transmission properties and compensation. LÄS MER

  5. 14. Protection for Multiterminal HVDC Grids - A Digital Contribution

    Författare :Ilka Jahn; Staffan Norrga; Hans-Peter Nee; Dirk Westermann; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HVDC transmission; power system protection; IED; real-time systems; test bench; field programmable gate array; open-source hardware; open-source software; power engineering education; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The aim of this thesis is to (1) enhance understanding of mechanisms that are important for the protection of high-voltage direct-current (HVDC) grids, and (2) suggest possible technical solutions. To that end, digital technologies were used both in simulation, as well as in a laboratory environment. LÄS MER
