  1. 11. Validation of a method utilising MR images for dose planning of prostate cancer treatment : Validation of new coil technology applied on the pelvis region of healthy volunteers

    Master-uppsats, Linköpings universitet/Institutionen för hälsa, medicin och vård

    Författare :Tova Rung; [2022]
    Nyckelord :Synthetic CT; Air coil;

    Sammanfattning : By generating a synthetic CT image (sCT) directly from the MRI, the electron density can be calculated, and the CT examination can be excluded from the patient flow minimizing the risk of uncertainties in the registration. Basing the radiation treatment process solely on MR images is called MRI-only and is beneficial for the patient as it can provide more accurate radiation treatment than the standardised treatment with fewer CT examinations and possibly a more cost-effective radiation treatment process.

  3. 12. Geophysical Data from Norrbotten, Sweden - Evidence for the Presence of a Crustal Scale Fault?

    Master-uppsats, Luleå tekniska universitet/Geovetenskap och miljöteknik

    Författare :Jimmy Markström; [2022]
    Nyckelord :Self-Organizing Maps; Magnetic Anomaly; Radioisotopes; Geological Faults;

    Sammanfattning : The method of combining multiple geophysical, geological, or geochemical datasets can reveal patterns of otherwise hidden features in the Earth’s crust. This may aid in geological mapping, locating economic mineral deposits and for general anomaly/feature detection. LÄS MER

  4. 13. Analysing the Effect of Working Memory Training on Brain Networks Using MEG and Neuroimaging

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Jeanie Dawnbringer; [2022]
    Nyckelord :Brain networks; Magnetoencephalography; Working memory; Plasticity; Neuroimaging;

    Sammanfattning : Introduction: The brain can change its structure and functionality as a result ofexternal factors. The working memory (WM) of the brain is where informationcan be held and manipulated during a short period of time, with the purpose ofachieving higher cognitive functions such as reasoning and learning.

  5. 14. Composite timber structures – Ribbed plate design : Evaluation of existing and development of new design methods

    Master-uppsats, Linnéuniversitetet/Institutionen för byggteknik (BY)

    Författare :Cristoffer Mård; [2022]
    Nyckelord :Ribbed plates; CLT; gamma-method; Timoshenko-method; shear analogy-method; FE-models; RFEM; Abaqus;

    Sammanfattning : Ribbed plates comprising cross-laminated timber slab, CLT, with glulam beams allow for increased span length compared to pure CLT slabs. At the moment the Eurocodes do not provide any recommendations to design a CLT plate or a ribbed plate. There are handbooks for designing ribbed plates. LÄS MER

  7. 15. Measuring the [C II]-to-H I connection in high-redshift absorption-selected galaxies

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Gaurav Senthil Kumar; [2022]
    Nyckelord :QSO; Quasar; Black Hole; AGN; Active Galactic Nuclei; DLA; Damped Lyman Alpha; C II; [C II]; H I; Sightline; HST; X-shooter; Spectroscopy; Echelle Spectroscope; Hyperfine transition; Hyperfine; Physics and Astronomy;

    Sammanfattning : HI neutral gas is the basic building block of galaxies. It dictates the star formation rate and hence the metal enrichment rates within high redshift galaxies. HI neutral gas cannot be directly observed beyond z ≈ 0. LÄS MER
