  1. 1. Gravitational Waves in Bimetric Gravity

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

    Författare :Erik Schildt; [2022]
    Nyckelord :;

    Sammanfattning : Understanding the cause of the accelerated expansion of the Universe is one of the most pressing issues in modern cosmology. An alternative to the LambdaCDM-model is bimetric gravity which is an extension of Einstein's theory of general relativity. LÄS MER

  3. 2. Technologies and Evaluation Metrics for On-Board Over the Air Control

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Aneysha Datta; [2022]
    Nyckelord :Wireless; Performance Metrics; WAVE; DMG; Intra-Vehicular Communication; BER; Simulink; Model-Based Design;

    Sammanfattning : This project has been carried out at the Electronic Embedded Systems Architecture Department at Volvo Construction Equipment (VCE), Eskilstuna, Sweden. It forms the baseline for a stepwise systematic research initiative to convert wired technologies used for certain in-vehicle control and communication components to wireless technologies. LÄS MER

  4. 3. Constructing Numerical Methods For Solving The Guiding Equation In Bohmian Mechanics

    Master-uppsats, Uppsala universitet/Materialteori

    Författare :Nilsson Robert; [2021]
    Nyckelord :Bohmian mechanics; De Broglie Bohm Theory; Numerical Methods;

    Sammanfattning : The aim of this thesis was to simulate a part of a proposed experiment by Lev Vaidman by using Bohmian mechanics. To do this a numerical method for solving the Schrödinger equation and theguiding equation was created, with several ways of making the simulation more efficient. LÄS MER

  5. 4. Semi-Classical Calculations of Multiple Trajectories in High-Harmonic Generation

    Kandidat-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Författare :Tom Causer; [2021]
    Nyckelord :hhg; high harmonic generation; trajectories; xuv; semi-classical; multiple; third trajectory; further; matlab; hhg approximation; simulation; far-field; near-field; fourier transform; Physics and Astronomy;

    Sammanfattning : The purpose of this thesis is to investigate the High-Harmonic Generation (HHG) process by simulating electron trajectories, and their resulting Extreme Ultra Violet (XUV) output. The HHG process is one in which a focused beam of infrared (IR) light can rival (in terms of intensity) the potentials of atoms, which makes tunnelling likely -- this sets off a chain of events resulting in an XUV pulse.

  7. 5. Beamforming in 5G mm-wave radionetworks : Importance of frequency multiplexing for users in urban macro environments

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

    Författare :Carl Lutnaes; [2020]
    Nyckelord :;

    Sammanfattning : 5G brings a few key technological improvements compared to previous generations in telecommunications. These include, but are not limited to, greater speeds, increased capacity and lower latency. These improvements are in part due to using high band frequencies, where increased capacity is found.
