  1. 1. Wayside Condition Monitoring System for Railway Wheel Profiles : Applications and Performance Assessment

    Författare :Matthias Asplund; Uday Kumar; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

    Sammanfattning : The railway is an important mode of transport, due to its environmental friendliness, high safety level, and low energy consumption combined with a high transport capacity, among other factors. The Swedish railway network is old, there has been almost no expansion of the network during the past few decades, and more traffic is expected. LÄS MER

  3. 2. A Formal Approach to Embedded High-Integrity Real-Time Systems

    Författare :Gustaf Naeser; Lars Asplund; Juan de la Puente; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap; Datavetenskap;

    Sammanfattning : Den här avhandlingen handlar inte om obskyra teoretiska datavetenskapliga hemligheter, den handlar om hur datorsystem kan göras säkrare. Ur ett annat perspektiv kan den sägas försöka sig på att göra svåra metoder, som formella sådana, lättare att använda så att fler programmerare och systemdesigners kan dra nytta av dem. LÄS MER

    Sammanfattning : Full deployment of Autonomous Vehicles (AVs) on public roads is challenging for organizations in the automotive domain in terms of developing safety standards and methods while taking legacy assumptions related to having a human driver and increased complexity and complexity handling into account. Specifically, the safety of AVs in the presence of other road users must be guaranteed as far as possible for different traffic scenarios. LÄS MER

  5. 4. Genetic aspects of stroke : association and linkage studies in a northern Swedish population

    Författare :Per-Gunnar Wiklund; Birgitta Stegmayr; Kjell Asplund; Dan Holmberg; Alun Evans; Umeå universitet; []

    Sammanfattning : Stroke is a common, multifactorial cardiovascular disease. A stroke event is the result of traditional risk factors (i.e. hypertension, diabetes, smoking), environmental exposures and genetic factors in a complex interplay. LÄS MER

  7. 5. Peer mentoring - A complementary support to persons after an acute myocardial infarction

    Författare :Lena Junehag; Marianne Svedlund; Kenneth Asplund; Eva Brink; Mittuniversitetet; []
    Nyckelord :Illness perception; Intervention; Longitudinal; Quality of life; Quasi-experimental; Recovery; Rural; Social support; Intervention; Kvasi-experimentell; Glesbygd; Livskvalitet; Longitudinell; Sjukdomsuppfattning; Social support; Återhämtning;

    Sammanfattning : The overall aim of the thesis was to investigate the experience of having an acute myocardial infarction in newly afflicted persons living in sparsely populated counties, and whether an intervention with peer mentors would provide support by affecting the perception of illness, health related quality of life and everyday life. The aim was also to describe the support of peer mentors from their perspective and what the mentoring meant to them. LÄS MER
