  1. 1. Analysis of Footbridge Comfort Vibrations

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Författare :Niklas Thuresson; Henrik Ruuth; [2023]
    Nyckelord :footbridges; dynamics; vibrations; accelerations; Sétra; comfort vibrations; natural frequencies; Technology and Engineering;

    Sammanfattning : The aim of this master's thesis was to investigate and increase the knowledge of how different parameters affect the dynamic properties of steel beam bridges used for pedestrian traffic. Steel footbridges are commonly used due to their high strength and low weight. LÄS MER

  3. 2. STANDARDIZED ORGAN AT RISK VOLUME FOR EXTERNAL BEAM RADIATION THERAPY IN PROSTATE CANCER AND ITS RELATIONSHIP TO VOLUMES DEFINED BY CLINICAL PRACTICE

    Master-uppsats,

    Författare :Dang Thao; [2022-01-13]
    Nyckelord :Medical physics; Radiation therapy; Prostate cancer; Organs at risk;

    Sammanfattning : Background/ Purpose: In radiation therapy (RT), the radiation dose calculated in tumours and normal tissue depends on how the volumes are defined. It is difficult to standardize how tumour volumes should be defined because their anatomical extension can differ greatly between individuals. LÄS MER

  4. 3. Improved side impact car safety : New IIHS side crash regulation, effect on product design

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Författare :Andreas Bäckman; [2022]
    Nyckelord :Side impact beam; IIHS; side crash; side impact crash testing; crash testing of automobiles; industrial design engineering; automotive design; product design; Sidokrockskydd; IIHS; sidokrock; sidokollision; sidokrocktestning; krocktest av bilar; teknisk design; bildesign; produktdesign;

    Sammanfattning : 23% of passenger vehicle occupant deaths in 2019 was side-impact collisions and is a ongoing problem that continues to take people’s lives (IIHS, 2021a). IIHS (Insurance Institute for Highway Safety) is an organization based in USA, which performs vehicle crash tests with the goal of making cars safer and reducing deaths and injuries. LÄS MER

  5. 4. Material decomposition using a photon counting X-ray detector in low energy range

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Rasmus Solem; [2021]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Material decomposition in X-ray imaging is used to separate different materials or elements in an image and to quantify their respective concentration. The material decomposition and quantification are made possible by the dependency of attenuation on the attenuating material and photon energy. LÄS MER

  7. 5. Active stabilisation of a micro-sized fibre cavity using tilt locking to enable quantum operations on single ions

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

    Författare :Jannek Hansen; [2021]
    Nyckelord :Quantum computation; optical cavity; microcavity; locking; tilt locking; cavity stabilization; Gaussian-Hermitian modes; quantum computer; higher-order transverse modes; Physics and Astronomy;

    Sammanfattning : In this thesis, the tilt locking scheme is applied to create an error signal that monitors length changes in a fibre-based microcavity. To find a robust and precise locking technique is an essential step towards quantum operations on single rare-earth ions doped in microcrystals. Quantum computing and information is a frontier of modern physics. LÄS MER
