  1. 1. Modeling of Low-Energy Neutron Scattering in Liquid Hydrogen Using NCrystal

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/European Spallation Source ESS AB; Lunds universitet/Kärnfysik

    Författare :Tim Günter; [2022]
    Nyckelord :ESS; European Spallation Source; neutron; scattering; moderator; liquid hydrogen; modeling; ncrystal; njoy; Physics and Astronomy;

    Sammanfattning : The European Spallation Source ESS, under construction in Lund, Sweden, aims to produce high-brightness and intensity neutrons for a multitude of experiments upon completion. An efficient production of neutrons requires elaborate understanding of the moderation process which slows the neutrons from relativistic speed to a kinetic energy of meV. LÄS MER

  3. 2. Comparing Four Modelling Methods for the Simulation of a Soft Quadruped Robot

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Karin Lagrelius; [2022]
    Nyckelord :Soft Robotics; Modelling; Simulation; Lumped-parameter-method; Quadruped; Soft Actuator; Matlab Simulink; Matlab Simscape Multibody; Mjuk robotik; Modellering; Simulering; Klumpparametermetoden; Fyrfota; Mjukt ställdon; Matlab Simulink; Matlab Simscape Multibody;

    Sammanfattning : A soft quadruped robot is being developed at the Department of Machine Design and Department of Production Engineering at KTH. The legs of the robot consist of four continuum actuators that can achieve complex movements. In order to efficiently develop gaits for the robot, reinforcement learning will be used. LÄS MER

  4. 3. Simulation of a prototype of the LDMX hadronic calorimeter and analysis of test beam data

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

    Författare :Péter György; [2022]
    Nyckelord :LDMX; HCal; TS; prototype; Physics and Astronomy;

    Sammanfattning : The Light Dark Matter eXperiment (LDMX) is an upcoming experiment to test the existence of dark matter in the mass range of 1 MeV - 1 GeV. It does so by looking for missing momentum and energy in collisions of an electron beam and a tungsten target, which could potentially indicate the existence of dark matter. LÄS MER

  5. 4. Structural intrusion, flow disturbance and spillway capacity : CFD modeling of the Torpshammar dam

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Adéle Wallin; [2018]
    Nyckelord :RNG k-ε model; VOF; Fluent; turbulence; rectangular beams; flow pattern; discharge capacity; flow velocity;

    Sammanfattning : At the Torpshammar dam two rectangular beams are situated upstream of the spillway gates to stabilize the sidewalls holding the embankment of the dam. A computational fluid dynamics (CFD) simulation of the dam with the bottom outlets open was made to investigate how the flow and discharge capacity is affected by the beams. LÄS MER

  7. 5. Patch loading resistance of welded I-beams : with respect to misaligned web stiffeners

    Master-uppsats, KTH/Stålbyggnad

    Författare :John-Alexander Boutzas; Dafina Zeka; [2016]
    Nyckelord :Patch loading; Stiffeners; I-beam; Plated steel structures; Abaqus; Simply supported beam;

    Sammanfattning : When a concentrated load is introduced perpendicular to the flanges of a steel beam, this condition is referred to as Patch loading (Gozzi, 2007). This occurrence is common in many steel structures, for example at supports or during launching of bridges. LÄS MER
