  1. 1. Reaction and Diffusion Phenomena in Biomimetic Nanoscale Reactors and Networks

    Författare :Kristin Sott; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; artificial cell; restricted geometries.; enzymatic reactions; micromanipulation; biomimetic; nanotubes; diffusion; Vesicles; networks; liposomes;

    Sammanfattning : Methods for construction of geometrically complex, fully connected surface-immobilized microscopic networks of phospholipid bilayer vesicles (1-50 µm in diameter) interconnected by lipid nanotubes (100-300 nm in diameter), have been developed. The networks have controlled connectivity and are well-defined with regard to the container size, content, angle between nanotube extensions, and nanotube length. LÄS MER

  3. 2. Distributed Detection in Cognitive Radio Networks

    Författare :Ahti Ainomäe; Mats Bengtsson; Tõnu Trump; Olav Tirkkonen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cognitive Radio; distributed estimation; distributed detection; Diffusion LMS; Diffusion Networks; Adaptive Networks; Spectrum Sensing; Energy Detection; Random Matrix; Largest Eigenvalue Detection.; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : One of the problems with the modern radio communication is the lack of availableradio frequencies. Recent studies have shown that, while the available licensed radiospectrum becomes more occupied, the assigned spectrum is significantly underutilized. LÄS MER

  5. 4. Spatial diffusion of telemedicine in Sweden

    Författare :Magnus Strömgren; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Telemedicine; Spatial diffusion; Sweden; Northern Sweden; Information technology; Networks; Health care delivery;

    Sammanfattning : “Telemedicine” denotes medicine at a distance using telecommunications and information technologies. The aim of the thesis is to reveal determinants and outcomes of telemedicine diffusion—that is, the spread of telemedicine in time and space. Telemedicine is examined both at the national level and in a regional case study. LÄS MER

  7. 5. Contagious Interactions : Essays on social and epidemiological networks

    Författare :Monica K. Nordvik; Fredrik Liljeros; Peter Hedström; Alden S. Klovdahl; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social networks; social network analysis SNA ; network epidemiology; sexually transmitted infections STI ; mathematical modeling; suicide; diffusion.; Sociology; Sociologi; Sociology; sociologi;

    Sammanfattning : This dissertation has two overall aims; to explore and develop the use of SNA in sociology, and to demonstrate that sociology has much to give to other sciences. Interdisciplinary collaboration is necessary because we do not live in a world in which subject areas are strictly isolated. LÄS MER
