  1. 11. Accuracy verification of GT-Power model and reduction of computational time

    University essay from KTH/Marcus Wallenberg Laboratoriet MWL

    Author : Viktor Dahl; Maja Dyrsmeds; [2022]
    Keywords : Vehicle acoustics; GT-Power; Exhaust system; Internal combustion engine;

    Abstract : The noise produced by any new vehicles is tightly regulated by the European Union which have developed a standardised method for measuring the emitted noise of new vehicles. The method involves a vehicle driving past carefully positioned microphones at a specific range of engine speeds. READ MORE

  3. 12. Design and evaluation of ambient RF energy harvesting platform for sensor-based systems : An experimental study of RF energy harvesting

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Ibrahim Hamed; [2022]
    Keywords : Radiofrekvensenergiskördning; Trådlös energiskördning; Backscattering-teknik; Programvarudefinierad radio; EMC; PCB; Antenn;

    Abstract : Trådlös energiskörd möjliggör förmågan att skörda energi från elektromagnetisk strålning. Med de senaste framstegen inom trådlös kommunikationsteknik och med tillgången till energieffektiva sensorer, så har radiofrekvensenergiskördning potential till att bli en självförsörjande sensorbaserad plattform.

  4. 13. Ageing of NCA/Graphite-Silicon Cells : Investigating the feasibility of accelerated ageing

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Gustav Giske; [2022]
    Keywords : ;

    Abstract : Reliable test data on cell ageing is important to have when deciding on which cell to use in a vehicle. Accelerated ageing could, if performed in a good way, increase the amount of information about the cell ageing in an early stage of a vehicle project, reducing the risk of costly battery replacements.

  5. 14. Developing data processing program for a new radio magnetotelluric (RMT) instrument

    University essay from Uppsala universitet/Geofysik

    Author : Elis Uebel; [2022]
    Keywords : RMT radio magnetotellurics matlab GUI;

    Abstract : The radio magnetotellucic (RMT) method originates from (Tikhonov, 1950) and (Cagniard,1953) who discovered the possibility to estimate resistivity in the Earth’s subsurface using naturally occurring telluric currents. This through measuring the surface impedance of electromagnetic waves. READ MORE

  6. 15. Nonlinear mode coupling and parametric amplification with superconducting kinetic inductance

    University essay from KTH/Tillämpad fysik

    Author : Daniele Lopriore; [2022]
    Keywords : Quantum technology; microwave engineering; nanofabrication; parametric amplifiers; multimode entanglement; kinetic inductance; Kvantteknologi; mikrovågsteknik; nanotillverkning; parametriska förstärkare; multimodentrassling; kinetisk induktans;

    Abstract : We investigate the resonant characteristics of superconducting meandering nanowires to design a nonlinear kinetic inductance traveling-wave parametric amplifier. The devices are patterned out of 15 nm thick NbTiN films. They consist of a coplanar waveguide, that shrinks into 100 nm wide meandering nanowires. READ MORE
