  1. 1. Evaluation of intrafractional motion for patients receiving whole brain radiotherapy in open-faced immobilisation masks

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Sara Falk; [2023]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Purpose/Background Patients receiving whole brain radiotherapy (WBRT) today are treated with an immobilisation mask which fully covers their face and therefore might be experienced as uncomfortable and claustrophobic. In recent years, optical surface scanning (OSS) systems have been implemented for patient positioning and real-time motion monitoring [1]. LÄS MER

  3. 2. Submillimeter 3D surface reconstruction of concrete floors

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Björn Hagström; Hampus Wallström; [2022]
    Nyckelord :Submillimeter; Structured light; Sinusoidal phase shift; Concrete; Surface reconstruction; Defocused binary pattern;

    Sammanfattning : During the creation of any concrete floor the concrete needs to be grinded down from it's very rough newly poured form to a more usable floor surface. Concrete floor grinding is very special in that the work area is often immensely large while the height difference on the surface is incredibly small, in-fact the the largest local difference of the surface from a peek to a valley during the grinding process is submillimeter and goes down to micrometer scale.

  4. 3. Study of CO Emission in Nine Hot Dust-Obscured Galaxies at z ∼3

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

    Författare :Timothy Faerber; [2021]
    Nyckelord :Galaxies; high-z; AGN; starburst; quasar; evolution; cosmology;

    Sammanfattning : Massive galaxies evolve through different phases including starburst-dominated and active galactic nuclei (AGN)-dominated phases. These phases are predicted to be prevalent at earlier times (z ∼ 2 − 3). LÄS MER

  5. 4. Assessment of weather conditions for ALMA observations of the Sun

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Daniel Jakobsson; [2020]
    Nyckelord :Atacama Large Millimeter Array; ALMA; Solar observation;

    Sammanfattning : The closest star to Earth is the Sun. The difference between our Sun and other stars is that the dynamics are observable with telescopes. A complex and strange part of our Sun is the chromosphere which is a part of the solar atmosphere. LÄS MER

  7. 5. SETI follow-up observations

    L3-uppsats, Uppsala universitet/Observationell astrofysik

    Författare :George Xystouris; [2016]
    Nyckelord :;

    Sammanfattning : The G-HAT team (G-HAT: Glimpsing Heat from Alien Technologies) compiled a catalogue of 93 galaxies that could host Kardashev-III civilizations [Griffith et al., 2015], using data from the WISE space telescope. LÄS MER
