    Sammanfattning : The utilisation of the THz spectrum ( 0.3-10 THz ) is hampered by fundamental difficulties in generating power at these frequencies. LÄS MER

  3. 2. Expansion Governance of the Integrated North Seas Offshore Grid

    Författare :João Gorenstein Dedecca; Paulien M. Herder; Rudi A. Hakvoort; Amineh Ghorbani; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Union; expansion planning; governance; HVDC; myopic optimization; North Seas; offshore grid; offshore wind; simulation;

    Sammanfattning : The expansion of offshore power transmission and generation in the North Seas of Europe is accelerating rapidly. This is due to several drivers, including the decarbonization and reform of the European power system, and innovations in offshore wind and high-voltage direct current transmission. LÄS MER

  4. 3. Sensitivity and Uncertainty Analysis Methods : with Applications to a Road Traffic Emission Model

    Författare :Olle Eriksson; Stig Danielsson; Rolf Sundberg; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Emission; Grid; Model; Pollutant; Response surface; Road traffic; Sensitivity analysis; Simulation; Uncertainty analysis; Avgaser; Vägtrafik; Miljöaspekter; Statistics; Statistik;

    Sammanfattning : There is always a need to study the properties of complex input–output systems, properties that may be very difficult to determine. Two such properties are the output’s sensitivity to changes in the inputs and the output’s uncertainty if the inputs are uncertain. LÄS MER

  5. 4. Looking for the Charged Higgs Boson : Simulation Studies for the ATLAS Experiment

    Författare :Martin Flechl; Tord Ekelöf; Richard Brenner; Kinnunen Ritva; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; charged Higgs; tau; ATLAS; HEP; CERN; LHC; Particle Physics; Grid; Physics; Fysik; högenergifysik; High Energy Physics;

    Sammanfattning : The discovery of a charged Higgs boson (H+) would be an unambiguous sign of physics beyond the Standard Model. This thesis describes preparations for the H+ search with the ATLAS experiment at the Large Hadron Collider at CERN. The H+ discovery potential is evaluated, and tools for H+ searches are developed and refined. LÄS MER

  7. 5. Simulation and Electrical Evaluation of 4H-SiC Junction Field Effect Transistors and Junction Barrier Schottky Diodes with Buried Grids

    Författare :Jang-Kwon Lim; Hans-Peter Nee; Mietek Bakowski; Ichiro Omura; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Silicon carbide SiC ; junction field-effect transistors JFETs ; junction barrier schottky diode JBS ; schottky barrier diode SBD ; buried-grid BG technology; simulation; implantation; epitaxial growth; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Silicon carbide (SiC) has higher breakdown field strength than silicon (Si), which enables thinner and more highly doped drift layers compared to Si. Consequently, the power losses can be reduced compared to Si-based power conversion systems. Moreover, SiC allows the power conversion systems to operate at high temperatures up to 250 oC. LÄS MER
