  1. 16. MRI Studies of the Fetal Brain and Cranium

    Författare :Nuno Canto Moreira; Johan Wikström; Raii Raininko; Daniela Prayer; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fetal MRI; Brain; Cranium; Development; Normal; Ear; Lip; Palate; Biometry; Hippocampus; Measurements; Radiologi; Radiology;

    Sammanfattning : Ultrasound is the primary modality for fetal imaging, but Magnetic Resonance Imaging nowadays has a valuable complementary role as it often reveals findings that alter pregnancy management. Knowledge on some clinically relevant areas of the normal fetal development is still lacking, and this was the aim of this project. LÄS MER

  3. 17. Model-based System Testing of Safety-Critical Embedded Software

    Författare :Muhammad Nouman Zafar; Wasif Afzal; Eduard Paul Enoiu; Cyrille Artho; Mälardalens universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : System-level testing of safety-critical embedded systems is complex and costly. MBT has shown promising results in terms of fault detection effectiveness and efficiency of test generation and execution. However, the industrial adoption of MBT approaches is slow and limited to specific industries and domains. LÄS MER

  4. 18. Gravitational waves from primordial magnetic sources

    Författare :Yutong He; Axel Brandenburg; David Weir; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This licentiate thesis gives an overview of modified gravity and primordial magnetic fields,bridged by gravitational waves (GWs) as a phenomenological probe of both sectors.First we derive the GW equation in a homogeneous and isotropic background from general relativity.

  5. 19. Why nothing matters : A tale of vacua in the early Universe

    Författare :Aliki Litsa; Katherine Freese; M. C. David Marsh; Marco Peloso; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; inflation; reheating; Higgs; cosmological phase transitions; Theoretical Physics; teoretisk fysik;

    Sammanfattning : The paradigm of inflation –  a period of accelerated expansion in the very early Universe –  was introduced to give solutions to a number of problems encountered in Standard Big Bang cosmology. Additionally, due to its quantum nature, inflation is able to generate the necessary primordial inhomogeneity “seeds”, which eventually evolve into large-scale structures. LÄS MER

  7. 20. Assessing infection risk and evaluating prevention strategies in the era of HPV-vaccines

    Författare :Amy Levál; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Aim: This thesis aims to provide a multidimensional assessment of infection risks and to evaluate strategies for HPV prevention including vaccination with quadrivalent HPV-vaccines, dose-level vaccine effectiveness and condom use in high STI risk situations. Methods: Multiple population-based registers and questionnaire responses provided data for this thesis. LÄS MER
