    Författare :Johan Karlsson; Luleå tekniska universitet; []
    Nyckelord :;

    Sammanfattning : This thesis deals with three different aspects of queues and buffers. First, how a novel memory architecture can improve a solution to the problem of supporting a priority queue with priorities from a bounded universe. LÄS MER

  4. 4. Health economics and its measures in rheumatoid arthritis

    Författare :Johan Karlsson; Reumatologi och molekylär skelettbiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cost-utility analysis; Cost-of-illness; Quality of life; EuroQol 5-Dimensions; Antirheumatic agents; TNF inhibition; Outcome assessment; Disease activity; Disability; Health economics; Rheumatoid arthritis;

    Sammanfattning : Objectives: To study: (I) the impact on cost-utility analyses of applying different national EuroQol 5-Dimensions (EQ-5D) preference sets; (II and III) whether, in methotrexate-refractory, early rheumatoid arthritis (RA), the addition of infliximab results in superior health-related quality of life (HRQoL) and may be considered cost-effective, as compared to adding sulfasalazine and hydroxychloroquine; (IV) how costs relate to disability (measured by the health-assessment questionnaire, HAQ), disease activity (28-joint disease activity score, DAS28) and HRQoL (EQ-5D) in RA. Methods: In the observational SSATG register, one-year quality-adjusted life-year (QALY) accumulation of two interventions was compared according to the UK, US, or Danish EQ-5D preference sets.

  5. 5. On data structures and memory models

    Författare :Johan Karlsson; Luleå tekniska universitet; []
    Nyckelord :;

    Sammanfattning : In this thesis we study the limitations of data structures and how they can be overcome through careful consideration of the used memory models. The word RAM model represents the memory as a finite set of registers consisting of a constant number of unique bits. LÄS MER
