  1. 1. Combating Intersymbol Interference and Cochannel Interference in Wireless Communication Systems

    Författare :Ronnie Gustafsson; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ISI; CCI; wireless systems; beamforming; beam; simulation; fading; equalizer; channel; smart antenna; antenna array; recursive least squares RLS ; adaptive algorithms; blind algorithms;

    Sammanfattning : Over the last decade the world has witnessed explosive growth in the use of wireless mobile communications. Looking around we find users with mobile phones, wireless PDAs, pagers, MP3 players, and wireless headphones to connect to these devices - a small testament of the impact of wireless communications on our daily lives.

  3. 2. Neural Stem and Progenitor Cells as a Tool for Tissue Regeneration

    Författare :Ulrika Wallenquist; Karin Forsberg Nilsson; Lars Hillered; Karin Holmqvist; Anders Lewén; Johan Bengzon; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatic brain injury; neural stem cells; transplantation; CNS; PNS; progenitor cells; inflammation; CCI; Biochemistry; Biokemi; Neurosurgery; neurokirurgi; Medical Biochemistry; medicinsk biokemi;

    Sammanfattning : Neural stem and progenitor cells (NSPC) can differentiate to neurons and glial cells. NSPC are easily propagated in vitro and are therefore an attractive tool for tissue regeneration. Traumatic brain injury (TBI) is a common cause for death and disabilities. A fundamental problem following TBI is tissue loss. LÄS MER

  4. 3. Ventilatory aspects of sleep and activity in patients with neuromuscular disorders

    Författare :Brita Klefbeck Stridsman; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :assisted ventilation; cervical cord injury; inspiratory muscle training; neuromuscular diseases; sleep; oximetry; trunk stability;

    Sammanfattning : Patients with cervical cord injuries (M) and slowly progressive neuromuscular diseases, such as prior polio and muscular dystrophy, often have decreased ventilatory capacity. This could affect both their daytime level of activity and sleep quality. LÄS MER

  5. 4. Clinical factors and outcome in T-cell lymphoma: a population-based perspective

    Författare :Fredrik Ellin; Tumörmikromiljö; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; T-cell Lymphoblastic Lymphoma; peripheral T-cell lymphoma; prognostic factors; autologous stem cell transplantation; central nervous system relapse; comorbidity;

    Sammanfattning : The heterogeneous group of T-cell lymphomas consist mostly of aggressive diseasess, with generally unfavourable outcome compared to aggressive B-cell lymphomas following similar therapy. This thesis focus on outcome and risk factors for inferior survival, in an unselected population-based cohort of T-cell lymphoma patients. LÄS MER

  7. 5. Aspects of platelet transfusions and the association between routine coagulation tests and outcome

    Författare :Sigurdur Benediktsson; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Patients with chemotherapy-induced bone marrow aplasia often develop severe thrombocytopenia which requires platelet transfusion. However, up to 25% of the patients show a less than adequate response to the transfusion. LÄS MER
