  1. 1. A Quality Assurance of NKT’s Temperature Measuring : Evaluation and Uncertainty Analysis of the Temperature Measuring Chain on High Voltage Cables

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Hannes Olausson; [2022]
    Keywords : Temperature; Uncertainty; Logger system; Thermocouple;

    Abstract : An overall increase of interest and need for high voltage cable have been acknowledge overthe last years. This is mainly due to the effect of the rapid expansion and transition fromfossil-energy sources to a future with non fossil-energy. READ MORE

  3. 2. Evaluation of thermal expansion in busbars used for battery electric vehicles

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : FREDRIK LARSSON; [2021]
    Keywords : Busbar; Battery electric vehicle; Thermal expansion; Cross-section shape;

    Abstract : Thermal expansion can be an issue in solid busbars, the expansion is caused by several factors and can cause plastic deformation in connection points or structure around it. The expansion occurs due to temperature differences in the busbar as a result of altered ambient temperature and/or joule heating. READ MORE

  4. 3. The Quantum Hall Effect

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Conrad Grälls; [2020]
    Keywords : quantum hall effect; QHE; fractional quantum hall effect; FQHE; hall effect;

    Abstract : The quantum Hall effect occurs when a conductor carrying a current is placed in a perpendicular magnetic field. If certain conditions are met, such as strong magnetic field and low temperature, the resistivity becomes quantised, taking values of integer or fractional multiples of h/e2. READ MORE

  5. 4. High Magnetic Field in Low Temperature Vacuum Conditions : Magnet Design, Modeling and Testing

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Nehir Schmid; [2020]
    Keywords : magnet; pulsed magnet; X-ray diffraction; crystallography; zylon; magnet design; magnetic field; high magnetic field; strong magnetic field; split-coil magnet;

    Abstract : The Swiss Free Electron Laser (SwissFEL) at the Paul Scherrer Institute is a national prestige project that will enable ground breaking new x-ray scattering experiments in areas such as biology, chemistry and physics. A plannedactivity is to generate possibility for x-ray diffraction under high pulsed magnetic fields to explore quantum mattermaterials. READ MORE

  6. 5. Combining the GW Approximation with the Hubbard I Approximation for strongly correlated materials

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Torsten Strunck; [2019]
    Keywords : GWA; GW Approximation; HIA; Hubbard I Approximation; Hubbard-I Approximation; Hubbard model; DMFT; Dynamical Mean Field Theory; strongly correlated materials; electron correlations; solid state physics; Physics and Astronomy;

    Abstract : In this thesis, the GW approximation (GWA, Green's function G times screened interaction W) and the Hubbard I approximation (HIA) are combined in a non-self-consistent one-shot calculation to determine the electronic structure of a one-dimensional strongly-correlated model. The scheme was chosen to incorporate both screening effects through the GWA and strong on-site correlations through the atomic HIA. READ MORE
