  1. 1. Analysis of a high step-up gain DC-DC converter for fuel cell and battery application

    Kandidat-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Kaj Törngren Sato; [2023]
    Nyckelord :Fuel cell; High step-up DC-DC converter; Boost converter; Coupled inductors; Coupling factor; CCM; DCM; Duty cycle;

    Sammanfattning : In sustainable energy systems those using fuel cells, high step-up gain converters are widely used to increase the output voltage to levels that can be used by other converters, such as inverters for grid connection or powering other AC loads. In order to obtain a higher voltage gain, in comparison to a traditional boost converter, often different topologies techniques are involved. LÄS MER

  3. 2. Constraining the Higgs width in Higgs production associated with a top quark pair

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Författare :Benjamin Dahlén; [2023]
    Nyckelord :Higgs; width; cross section; on-shell; off-shell; invariant mass; Standard model; upper bound; Physics and Astronomy;

    Sammanfattning : In this thesis we study the width of the Higgs boson in the process pp → t ̄t 4l at LO using MadGraph5_aMC@NLO to generate the events. The contributions including the Higgs signal, continuum background and interference were considered in order to calculate the expected number of events in a broad range of four-lepton invariant masses.

  4. 3. Cavity Beam Position Monitors State of the Art and Design Studies in the Context of the ILC Project

    Master-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen; Lunds universitet/Lunds Tekniska Högskola

    Författare :Laura Karina Pedraza Motavita; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The aim of this master thesis project is the study and evaluation of the design of cavity beam position monitors (BPM) for the International Linear Collider (ILC) project. The state-of-the-art of BPMs is investigated to determine the most appropriate existing BPM design for the requirements of the ILC. LÄS MER

  5. 4. Possible Bow Shock Current Closure to Earth's High Latitude Ionosphere on Open Field Lines

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

    Författare :Gabriella Nordin; [2023]
    Nyckelord :Space Physics; Bow Shock Current; Field-Aligned Currents; Open Field Lines;

    Sammanfattning : The bow shock is formed due to the abrupt deceleration of the supersonic solar wind in front of the terrestrial magnetic field. The solar wind plasma and the Interplanetary Magnetic Field (IMF) are both compressed across the shock, and according to Ampère's law a current thus flows on the bow shock at all times. LÄS MER

  7. 5. Synthesis and analysis of potential metabolites of ADB-5´Br-BUTINACA

    Kandidat-uppsats, Linköpings universitet/Kemi

    Författare :Alaa Malekshahineia; [2023]
    Nyckelord :metabolites; NPS; synthetic cannabinoids;

    Sammanfattning : In recent years, there has been a rise in the use of New Psychoactive Substances (NPS) that mimic the effects of controlled drugs and licensed medicines, which have become a significant public health concern globally. Synthetic cannabinoids, a rapidly expanding category of NPS, with much higher potency and binding affinity to the cannabinoid receptors than ∆9-tetrahydrocannabinol (THC), have led to serious psychiatric complications and other adverse effects.
