  1. 21. Digitally Controlled Oscillator Topologies for mm-Wave Pulsed Coherent Radar

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Klas Junskog; [2023]
    Nyckelord :oscillators; mm-wave; radar; Technology and Engineering;

    Sammanfattning : The advancement of future generations of wireless communication and radar sensing warrants the need for mm-wave digitally controlled oscillators (DCOs) with high-frequency trade-offs in consideration. The purpose of this project is to investigate DCO topologies inspired from scientific literature. LÄS MER

  3. 22. Monetary Policy with Credit Market Frictions

    D-uppsats, Handelshögskolan i Stockholm/Institutionen för nationalekonomi

    Författare :Mambuna Njie; [2023]
    Nyckelord :Monetary policy; Investments; Credit frictions; Collateral constraints;

    Sammanfattning : I study the role of collateral as a source of financial friction in the transmission of monetary policy towards firms' investments. First, I use a panel of Swedish firms to estimate the heterogeneity in firm investment responses to monetary policy shocks conditional on collateral. LÄS MER

  4. 23. Methods for determining focal point and delay for ultrasound arrays and multichannel electronics

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Svante Rosenlind; [2023]
    Nyckelord :Focusing algorithms; k-wave; Spatiotemporal inverse filter; Gerchberg- Saxton algorithm; Focused ultrasound; Technology and Engineering;

    Sammanfattning : High intensity focused ultrasound is a growing technique for tissue ablation, among other uses, and given its destructive capabilities, there is a need for control of where the energy is delivered. There exist a number of methods for focusing such ultrasound arrays, but these often assume prior knowledge of the impulse response, or require extensive full-system simulations. LÄS MER

  5. 24. Development of Friction/Blended Braking Capability for an Electric Driveline Model for Multi-Scale Road-Cargo Simulations

    Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesign
