  1. 11. 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

  3. 12. Duplicate detection of multimodal and domain-specific trouble reports when having few samples : An evaluation of models using natural language processing, machine learning, and Siamese networks pre-trained on automatically labeled data

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

    Författare :Viktor Karlstrand; [2022]
    Nyckelord :Duplicate detection; Bug reports; Trouble reports; Natural language processing; Information retrieval; Machine learning; Siamese neural network; Transformers; Automated data labeling; Shapley values; Dubblettdetektering; Felrapporter; Buggrapporter; Naturlig språkbehandling; Informationssökning; Maskininlärning; Siamesiska neurala nätverk; Transformatorer; Automatiserad datamärkning; Shapley-värden;

    Sammanfattning : Trouble and bug reports are essential in software maintenance and for identifying faults—a challenging and time-consuming task. In cases when the fault and reports are similar or identical to previous and already resolved ones, the effort can be reduced significantly making the prospect of automatically detecting duplicates very compelling.

  4. 13. Kvalitativ studie gällande organisationers användning av molntjänster

    Uppsats för yrkesexamina på grundnivå, Högskolan i Gävle/Avdelningen för datavetenskap och samhällsbyggnad

    Författare :Ronja Pyykkö Sandblom; [2022]
    Nyckelord :Cloud computing; decision-making process; threats; security; policy; organizations; authorities; GDPR; Molntjänster; beslutsprocess; hot; säkerhet; policy; organisationer; myndigheter; GDPR;

    Sammanfattning : Molntjänster har funnits sedan en lång tid tillbaka. Med åren har allt fler börjat använda dessa tjänster, vilket har gjort att det är ett högaktuellt ämne. Cirka 75 procent av företag använder sig av molntjänster och det ses som nödvändigt för digitaliseringen i svensk offentlig sektor. LÄS MER

  5. 14. 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.

  7. 15. Computational Scaling of Party Cohesion in Social Media: A Case Study on Twitter Campaigns in Brazil

    Kandidat-uppsats, Lunds universitet/Statsvetenskapliga institutionen

    Författare :Emma Olivia Baker; [2022]
    Nyckelord :party cohesion; Brazil; social media; political campaigns; Wordfish; Social Sciences;

    Sammanfattning : This thesis explores party cohesion in politicians’ social media campaigns in the context of Brazil. It highlights the importance of studying the interaction between digitalisation of political communication and the party system in developing democracies. Brazil makes an interesting case as it is known for its exceptionally unstable party system. LÄS MER
