  1. 21. Intra-industry trade: measurements, determinants and growth : a study of Swedish foreign trade

    Författare :Pär Hansson; Lars Lundberg; David Greenaway; Örebro universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Intra-industry trade; determinants; comparative costs; factor intensity; product differentiation; elasticity of substitution; economies of scale; quasi-homothetictastes; Sweden; Economics; Nationalekonomi;

    Sammanfattning : The conclusions are that a traditional factor proportions model seems neither theoretically nor empirically to explaing IIT. However, a relaxation of the assumption of homogeneous products in an industry gives rise to several implications for IIT. LÄS MER

  3. 22. Ergonomics at Home : Design for Safe Living and Home Care

    Författare :Jenny Hjalmarson; Tore Johan Larsson; Stefan Lundberg; Lars Nyberg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ergonomics; aging; work posture; four-wheeled walker; home care worker; living at home; accessibility;

    Sammanfattning : The home should represent safety and security for the person who lives there, and this is an important factor for independence and autonomy in very old age. With aging populations, the needs for long-term care increase, care provided by spouses and/or from the growing home care sector. Injuries among these groups are common. LÄS MER

  4. 23. Parallel algorithms for real-time railway rescheduling

    Författare :Sai Prashanth Josyula; Johanna Törnquist Krasemann; Lars Lundberg; Mats Brorsson; Blekinge Tekniska Högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In railway traffic systems, it is essential to achieve a high punctuality to satisfy the goals of the involved stakeholders. Thus, whenever disturbances occur, it is important to effectively reschedule trains while considering the perspectives of various stakeholders. LÄS MER

  5. 24. Parallel algorithms for solving the train timetable rescheduling problem

    Författare :Sai Prashanth Josyula; Johanna Törnquist Krasemann; Lars Lundberg; Blekinge Tekniska Högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Parallel computing; Parallel heuristic search algorithms; Computer Science; Datavetenskap;

    Sammanfattning : In railways, it is essential to achieve high train punctuality. Thus, whenever disturbances occur, it is important to reschedule the trains effectively. This task is typically handled manually by traffic controllers in real-time. LÄS MER

  7. 25. Health problems and work-related stress in Swedish ambulance personnel

    Författare :Kåre Karlsson; Lennart Christensson; Anders Jonsson; Lars Lundberg; Jan Mårtensson; Per-Olof Michel; Jönköping University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; work-related stress; ambulance personnel; cortisol; heart rate;

    Sammanfattning : Background: Previous studies have shown a high incidence of both acute and post-traumatic stress among ambulance personnel. It has been shown that ambulance personnel are at a higher risk of being affected of heart disease, high blood pressure and cancer. Studies have also seen a higher incidence of substance abuse and suicide. LÄS MER
