  1. 1. Surface Guided Helical Tomotherapy for Total Marrow Irradiation

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Hedda Enocson; [2022]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Background: Total marrow irradiation (TMI) with helical tomotherapy treatment (HT-TMI) can be used as conditioning regimen for leukemia patients prior to stem cell transplantation by radiating the skeletal tissue. To ensure adequate dose coverage a margin is applied to the clinical target volume (CTV), i.e. planning target volume (PTV) margin. LÄS MER

  3. 2. Free-Space Dark Pulse Mode-Locked Laser

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Martin Brunzell; [2021]
    Nyckelord :Solid State Laser; Sum-frequency generation; Dark pulse; Mode-locked; Laser; Summa-frekvens generation; mörk puls; modlåst;

    Sammanfattning : While the development of bright pulses produced in free space devices can be found in a large set of applications and research equipment all over the world. The production of dark pulses in a free-space device has not been shown prior to this work. LÄS MER

  4. 3. Electronic states in semiconductor double quantum dots and quantum rings - Theory and tight-binding modeling

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Calle Stenberg; [2021]
    Nyckelord :double quantum dots quantum rings tight-binding aharonov-bohm g-factor enhancement InAs; Physics and Astronomy;

    Sammanfattning : In recent experiments on semiconductor nanowires and quantum dots, enhanced g-factors up to several times the bulk value have been measured [1] [2]. The enhancement is attributed to orbital contributions g∗orb to the effective g-factor g∗ = g∗spin+g∗orb from the coupling of the high angular momentum ring-like states to the magnetic field.

  5. 4. Strengthening Efficiency and Safety in Forklift Operations through Autobiographical Design

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

    Författare :Nino Khodr; [2021]
    Nyckelord :Forklifts; Warehouse; Efficiency; E-Commerce; Internet of things.;

    Sammanfattning : Forklift vehicles used for moving pallets and boxes in warehouses, have recently been integrated with Internet of Things (IoT) technology, in effect making forklifts networked and in parts controllable from afar. Human operators now carry out tasks according to instructions displayed on the screen of the IoT-forklift instead of just maneuvering around and executing tasks as they see fit. LÄS MER

  7. 5. FOLAR: A FOggy-LAser Rendering Method for Interaction in Virtual Reality

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

    Författare :Tianli Zhang; [2020]
    Nyckelord :Computer Graphics; Volumetric Rendering; Virtual Reality; Particle System; Participating Media; Illumination; Real-time Rendering;

    Sammanfattning : Current commercial Virtual Reality (VR) headsets give viewers immersion in virtual space with stereoscopic graphics and positional tracking. Developers can create VR applications in a working pipeline similar to creating 3D games using game engines. LÄS MER
