  1. 1. InP DHBT Amplifiers and Circuit Packaging up to Submillimeter-Wave Frequencies

    Författare :Klas Eriksson; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; InP; WR05; packaging; noise figure; substrate modes; WR03.; multiple layer interconnect; double heterojunction bipolar transistor DHBT ; G-band; wideband; H-band; waveguide transition; distributed amplifier DA ; millimeter-wave; amplifier; low-noise amplifier LNA ; membrane technology; waveguide module; submillimeter-wave;

    Sammanfattning : This thesis treats the design and characterization of amplifiers operating up tosubmillimeter-wave frequencies and packaging of such circuits into waveguidemodules. The circuits use an advanced indium phosphide (InP) double heterojunctionbipolar transistor (DHBT) process with a multilayer back-end. LÄS MER

  2. 2. Bacterial viruses targeting multi-resistant Klebsiella pneumoniae and Escherichia coli

    Författare :Harald Eriksson; Anders Nilsson; Elisabeth Haggård-Ljungquist; Klas Flärdh; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Bacterial viruses; Bacteriophage; Phage; Phage therapy; multi-resistant bacteria; Klebsiella pneumoniae; molekylärgenetik; Molecular Genetics;

    Sammanfattning : The global increase in antibiotic resistance levels in bacteria is a growing concern to our society and highlights the need for alternative strategies to combat bacterial infections. Bacterial viruses (phages) are the natural predators of bacteria and are as diverse as their hosts, but our understanding of them is limited. LÄS MER

  3. 3. Arbete till varje pris : Arbetslinjen i 1920-talets arbetslöshetspolitik

    Författare :Lena Eriksson; Klas Åmark; Jonny Hjelm; Stockholms universitet; []
    Nyckelord :HUMANITIES; HUMANIORA; HUMANIORA; HUMANITIES; work approach; unemployment; relief work; norms; gender; implementation; social categorisation; History subjects; Historieämnen;

    Sammanfattning : When Sweden was hit by the massunemployment of the 1920s the preferred way of distributing the help to the unemployed was to engage them in publicly financed and run relief works. This dissertation investigates why the work approach made such a strong imprint on the Swedish unemployment policy. LÄS MER

  4. 4. On avoiding and completing colorings

    Författare :Lan Anh Pham; Klas Markström; Carl Johan Casselgren; Victor Falgas-Ravry; Roland Häggkvist; Kimmo Eriksson; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Graph coloring; precoloring; list assignment;

    Sammanfattning : All of my papers are related to the problem of avoiding and completing an edge precoloring of a graph. In more detail, given a graph G and a partial proper edge precoloring φ of G and a list assignment L for every non-colored edge of G, can we extend φ to a proper edge coloring of G which avoids L? In Paper I, G is the d-dimensional hypercube graph Qd, a partial proper edge precoloring φ and a list assignment L must satisfy certain sparsity conditions.
