  1. 1. Immunomodulation and immunopathogenesis in autoimmune disease with emphasis on autoimmune neuritis and arthritis

    Författare :Lei Bao; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Experimental autoimmune neuritis (EAN) and arthritis are CD4+ T cell mediated autoimmune animal models for the study of immunomodulation and immunopathogenesis of human Guillain-Barré syndrome (GBS) and rheumatoid arthritis (RA). Inflammatory cell infiltration and cytokine production in the target organs are characteristic features of both diseases, suggesting a role of cytokine production in the pathogenesis. LÄS MER

  3. 2. Control over Low-Rate Noisy Channels

    Författare :Lei Bao; Mikael Skoglund; Sandro Zampier; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sensor networks; linear quadratic cost; stochastic control; joint source–channel coding; joint coding and control; rate allocation; soft source de- coding; Telecommunication; Telekommunikation;

    Sammanfattning : Networked embedded control systems are present almost everywhere. A recent trendis to introduce radio communication in these systems to increase mobility and flex-ibility. LÄS MER

  4. 3. Source-channel coding for closed-loop control

    Författare :Lei Bao; Mikael Skoglund; Karl Henrik Johansson; Fredrik Gunnarssson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optimal control; joint source--channel coding; source-channel coding; joint coding and control; certainty equivalence; linear quadratic control; stochastic control; wireless sensor network; Telecommunication; Telekommunikation;

    Sammanfattning : Networked embedded control systems are present almost everywhere. A recent trend is to introduce wireless sensor networks in these systems, to take advantage of the added mobility and flexibility offered by wireless solutions. In such networks, the sensor observations are typically quantized and transmitted over noisy links. LÄS MER
