  1. 1. Offentlig upphandling - primärrättens reglering av offentliga kontrakt

    Författare :Andrea Sundstrand; Wiweka Warnling Nerep; Rolf Höök; Jane Reichel; Tobias Indén; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; public procurement; EU law; public contracts; serive concessions; B-services; below thresholds; EU primary law; remedies; crossborder interest; public procurement directives; offentlig upphandling; offentliga kontrakt; tjänstekoncessioner; B-tjänster; under tröskelvärdena; primärrätt; rättsmedel; gränsöverskridande intresse; upphandlingsdirektiv; offentlig rätt; Public Law;

    Sammanfattning : The objective of this thesis is EU primary legislation on public procurement. The award of public contracts below the thresholds, for B-services and for service concessions are excluded from the EU public procurement directives. LÄS MER

  3. 2. Soft X-ray Scattering Dynamics Close to Core Ionization Thresholds in Atoms and Molecules

    Författare :Johan Söderström; Jan-Erik Rubensson; Lorenzo Avaldi; Uppsala universitet; []
    Nyckelord :Physics; Soft X-ray emission; Resonant inelastic X-ray scattering; Double excitations; Helium; X-ray-emission-threshold-electron coincidence; Fysik;

    Sammanfattning : In this Thesis studies of highly excited states in gas-phase atoms and molecules (He, Ne, N2, O2, N2O and CO2) using a variety of synchrotron-radiation based techniques are presented. The three techniques used most frequently are X-ray-emission-threshold-electron coincidence (XETECO), X-ray emission spectroscopy (XES) and X-ray photoelectron spectroscopy (XPS) and they are all given a brief introduction.

  4. 3. Photodetachment Studies of Negative Ion Structure

    Författare :Gunnar Haeffler; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The structure of atomic negative ions has been investigated experimentally by studying photodetachment, which is the process of photon-induced electron emission from a negative ion. The interaction between the valence electrons and the nucleus is weaker in negative ions than in atoms and positive ions. LÄS MER

  5. 4. Cognitive Sensing and Transmission Strategies

    Författare :Kasra Haghighi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hidden Markov Model; Spectrum Sensing; Sequential Spectrum Sensing; Cognitive Radio; Spectrum Utilization;

    Sammanfattning : Many frequency bands for wireless services are severely underutilized by the primary users (PU) to which these bands are assigned. This motivates cognitive radios (CR), which identifies vacant spectrum and transmit accordingly. Many algorithms, some as simple as energy detection, are used to sense the spectrum. LÄS MER

  7. 5. Physical loads and aspects of physical performance in middle-aged men and women

    Författare :Margareta Torgén; Uppsala universitet; []
    Nyckelord :Medical sciences; physical work load; age; gender; muscle strength; aerobic power; sensory threshold; epidemiology; questionnaire; reproducibility; validity; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Clinical Physiology; klinisk fysiologi;

    Sammanfattning : This investigation aimed at a description of different aspects of physical loads during a 24 year follow-up (1970-1993) in 484 men and women born between 1935 and 1952, in relation to different aspects of physical performance, as measured at follow-up. The subjects were originally recruited in 1969 from the Stockholm county generalpopulation. LÄS MER
