  1. 21. Risk, Resilience and Insurance in Sudanese Pastoralism

    Master-uppsats, Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

    Författare :Alla Safieldin; [2019]
    Nyckelord :Climate change adaptation; Disaster risk management; Drought; Index-based livestock insurance; Pastoralism; Risk; Resilience; Sudan; Earth and Environmental Sciences;

    Sammanfattning : The nomadic pastoralists of the Sahel are often identified as a group at the frontline of global climate change. Their existence in arid and semi-arid regions and their reliance on seasonal rainfall are among the factors that contribute to their vulnerability to drought and climate shocks. LÄS MER

  3. 22. Prioritering av åtgärder för förbättrad juverhälsa i automatiska mjölkningssystem

    Kandidat-uppsats, SLU/Dept. of Animal Nutrition and Management

    Författare :Elna Laxmar; [2019]
    Nyckelord :automatiska mjölkningssystem; somatiskt celltal; juverhälsa; förebyggande;

    Sammanfattning : Svensk mjölkproduktion har under de senaste 30 åren genomgått stora strukturförändringar. Allt fler gårdar väljer att ställa om från uppbundna system till lösdrifter med ökad mekanisering och automatisering. 40% av svenska mjölkkor kopplade till Växa Sveriges program kokontrollen mjölkas numera i automatiska mjölkningssystem (AMS).

  4. 23. Women’s Perceived Safety on Public Transport Journeys : A Qualitative Study

    Master-uppsats, KTH/Urbana och regionala studier

    Författare :Lina Bergdahl; [2019]
    Nyckelord :perceived safety; fear of crime; public transport; whole-journey perspecitve; go-along method; walk-along; travel diaries; gendered mobility;

    Sammanfattning : Women feel more fear than men in public space and when using public transport. This is an inequality in our society which limits women’s mobility and access to public goods. This study aims to qualitatively explore how women experience their public transport trips from a perceived safety perspective in a study of Gullmarsplan. LÄS MER

  5. 24. Numerical analysis of aerodynamic damping in a transonic compressor

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Vincenzo Stasolla; [2019]
    Nyckelord :transonic compressor; flutter; vibration; CFD; transonic kompressor; fladder; vibration; CFD;

    Sammanfattning : Aeromechanics is one of the main limitations for more efficient, lighter, cheaper and reliable turbomachines, such as steam or gas turbines, as well as compressors and fans. In fact, aircraft engines designed in the last few years feature more slender, thinner and more highly loaded blades, but this trend gives rise to increased sensitivity for vibrations induced by the fluid and result in increasing challenges regarding structural integrity of the engine.

  7. 25. PCA based dimensionality reduction of MRI images for training support vector machine to aid diagnosis of bipolar disorder

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

    Författare :Beichen Chen; Amy Jinxin Chen; [2019]
    Nyckelord :Bipolar disorder; diagnosis; computer-aided medical diagnosis; SVM; Support vector machine; PCA; Principal component analysis; dimensionality reduction; feature reduction; neuroimaging; MRI; sMRI; machine learning; classification; psychiatric disorders; mental illness; Bipolär sjukdom; diagnotisering; datorstödd medicinsk diagnotisering; SVM; stödvektormaskin; PCA; principalkomponentanalys; MRI; magnetisk resonanstomografi; MRT; dimensionalitetsreduktion; maskininlärning; dimensionsreduktion; klassificering; psykiska sjukdomar;

    Sammanfattning : This study aims to investigate how dimensionality reduction of neuroimaging data prior to training support vector machines (SVMs) affects the classification accuracy of bipolar disorder. This study uses principal component analysis (PCA) for dimensionality reduction. LÄS MER
