  1. 21. Design and Fabrication of a Kinetic Inductance Parameric Amplifier for multi-mode entanglement studies

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Sara Persia; [2022]
    Nyckelord :Parametric amplifier; kinetic inductance; superconducting NbTiN nanowires; Parametrisk förstärkare; kinetisk induktans; supraledanden NbTiN- nanotrådar;

    Sammanfattning : Parametric amplifiers are essential for analyzing and measuring the weak signals generated byquantum circuits at cryogenic temperatures. This project aims to realize a low noise travelingwave parametric amplifier (TWPA) by exploiting the nonlinear current dependence of thekinetic inductance of superconducting NbTiN nanowires. LÄS MER

  2. 22. Origami Technology for Antennas and Devices in Different Fields

    Master-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Författare :Rumman Nasir; [2022]
    Nyckelord :Origami Technology; Antennas;

    Sammanfattning : This report explores the use of origami techniques in the space, medical and military fields. This new design method will modify the design process and reduce costs. The origami design method will also improve the device’s performance and quality of the device. LÄS MER

  3. 23. Learning by Digging : A Differentiable Prediction Model for an Autonomous Wheel Loader

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Arvid Fälldin; [2022]
    Nyckelord :Wheel loader; Deep learning; Autonomous; Multibody and soil dynamics;

    Sammanfattning : Wheel loaders are heavy duty machines that are ubiquitous on construction sites and in mines all over the world. Fully autonomous wheel loaders remains an open problem but the industry is hoping that increasing their level of autonomy will help to reduce costs and energy consumption while also increasing workplace safety.

  4. 24. Searching for direct collapse black holes using the James Webb Space Telescope

    Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Edison Arellano Almeida; [2022]
    Nyckelord :extragalactic astronomy;

    Sammanfattning : Recent detections of massive quasars at z > 6 has proven to be an interesting challengefor cosmology given the short time frame that these objects have to reach a certainmass via conventional methods (e.g., galaxy mergers). LÄS MER

  5. 25. Approximation of Analytic Functions by Faber Polynomials, the Grunsky Matrix, and a Univalence Criterion

    Kandidat-uppsats, KTH/Fysik

    Författare :Mina Farag; [2022]
    Nyckelord :Faber polynomials; Approximation of functions; Grunsky matrix; univalence criterion;

    Sammanfattning : The aim of this thesis is derive a set of polynomials defined on simply connected domains, the Faberpolynomials, in which all analytic function on the domain can be uniformly approximated. Importantconcepts and theorems such as isomorphisms, automorphisms and the Riemann mapping theorem areintroduced. Examples and applications are also included. LÄS MER
