  1. 1. Automotive Electromagnetic Compatibility - Prediction and Analysis of Parasitic Components in Conductor Layouts

    Författare :Sabine Alexandersson; Industriell elektroteknik och automation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Parasitic components; Electromagnetic Compatibility; Crosstalk; Electromagnetic simulations;

    Sammanfattning : The electronics in the automotive industry is facing a new era where safety critical functions are electrified, as for example drive-by-wire technology. At the same time as the number of electrical loads in the vehicles is increasing, the time to market is decreasing. LÄS MER

  3. 2. Superconducting quantum circuits in a tunable electromagnetic environment

    Författare :Silvia Corlevi; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis presents the results of an experimental study onsmall-capacitance Josephson junctions in a high impedanceenvironment. In small-capacitance Josephson junctions the charging energyEC=e2/2C becomes relevant at low temperature and thecharging effects influence the transport properties. LÄS MER

  5. 4. Office work and physical factors : health aspects of electromagnetic fields and light

    Författare :Monica Sandström; Kjell Hansson Mild; Gunnar Nordberg; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Facial skin symptoms; office illness; electrical hypersensitivity; physical environment; flicker; jitter; neurophysiological effects;

    Sammanfattning : The overall aim of this thesis is to increase our knowledge of the physical environment of office workers with special focus on electromagnetic fields and to address the question of whether electromagnetic fields can directly or indirectly contribute to symptoms or discomfort among video display terminal ( VDT) workers. Furthermore, we have measured light modulation from various commonly used light sources in laboratory conditions and, as a second step, used modulated light as stimulus for provocation of neurophysiological responses in persons with perceived “electrical hypersensitivity” (EHS).

  7. 5. Quantum effects in nanoscale Josephson junction circuits

    Författare :Silvia Corlevi; David B. Haviland; Jukka Pekola; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Josephson junctions; Josephson junction arrays; electromagnetic environment; Cooper pair transistor; parity effects; Physics; Fysik;

    Sammanfattning : This thesis presents the results of an experimental study on single-charge effects in nanoscale Josephson junctions and Cooper pair transistors (CPTs). In nanoscale Josephson junctions the charging energy EC becomes significant at sub-Kelvin temperatures and single-charge effects, such as the Coulomb blockade of Cooper pair tunneling, influence the transport properties.
