  1. 41. Cosmological Models and Singularities in General Relativity

    Författare :Patrik Sandin; Claes Uggla; Alan Coley; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; general relativity; Bianchi cosmology; singularities; dynamical systems; Fuchsian methods; Hamiltonian methods; Theory of relativity; gravitation; Relativitetsteori; gravitation; Physics; Fysik;

    Sammanfattning : This is a thesis on general relativity. It analyzes dynamical properties of Einstein's field equations in cosmology and in the vicinity of spacetime singularities in a number of different situations. LÄS MER

  3. 42. Screening for silent cardiac disease in an elderly population aiming at stroke reduction

    Författare :Katrín Ragna Kemp Guðmundsdóttir; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : INTRODUCTION: Atrial Fibrillation is the most common clinical arrhythmia and affects over 30 million people worldwide. Atrial fibrillation is a leading cause of morbidity and mortality worldwide with death, stroke and heart failure being the most feared complications. LÄS MER

  4. 43. Atrial fibrillation in aging; methodological aspects and the relation to dementia and cerebral vascular disease

    Författare :Lina Rydén; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; atrial fibrillation; dementia; stroke; silent brain infarcts; white matter hyperintensity; cerebral microbleed; small vessel disease; epidemiology;

    Sammanfattning : Emerging evidence suggest an increased risk of dementia in individuals with atrial fibrillation (AF). However, until recently, few studies have investigated the relation between AF and dementia taking both prevalent and incident stroke into account. LÄS MER

  5. 44. Hereditary Breast Cancer in South Sweden. Early findings from studies on the role of BRCA1

    Författare :Oskar Thor Johannsson; Bröstcancer-genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; survival analysis; CGH; mRNA in situ hybridization; germline mutations; LOH; Breast neoplasm; BRCA1; Cytology; oncology; cancerology; Cytologi; onkologi; cancer;

    Sammanfattning : The thesis presents the results from investigations into the role of BRCA1 in hereditary cancer in South Sweden. Loss of heterozygosity (LOH) studies found loss of the wildtype allele of BRCA1 to be common in BRCA1 associated breast cancer, but due to the high degree of LOH on chr. LÄS MER

  7. 45. Towards Accurate Estimation of Error Sensitivity in Computer Systems

    Författare :Fatemeh Ayatolahi; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; silent data corruption; error sensitivity; fault injection; soft errors;

    Sammanfattning : Fault injection is an increasingly important method for assessing, measuringand observing the system-level impact of hardware and software faults in computer systems. This thesis presents the results of a series of experimental studies in which fault injection was used to investigate the impact of bit-flip errors on program execution. LÄS MER
