  1. 1. Spatial and spatio-temporal processing with antenna arrays in wireless systems

    Författare :David Astély; KTH; []
    Nyckelord :;

    Sammanfattning : This thesis treats some modeling and estimation problems inthe fieldof antenna array signal processing. With multipleantennas at thereceive side, the spatial dimension is added,and processing is performed in both the temporal and spatialdomain. LÄS MER

  3. 2. Spatial Analysis and Modeling for Health Applications

    Författare :Lars Skog; Yifang Ban; Matthew Smallman-Raynor; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sweden; spatial analysis; spatial modeling; spatio-temporal spread; epidemiology; pandemic; walkability; health; Russian influenza; Asian influenza; A H1N1 pdm09; GWM; climate factors;

    Sammanfattning : Despite the benefits of applying methods of geographic information science (GIScience), the use of such methods in health service planning and provision remains greatly underutilized. Spread of epidemic diseases is a constant threat to mankind and the globalization of the world increases the risk for global attacks from multi-resistant bacteria or deadly virus strains. LÄS MER

  4. 3. The Financialization of the Swedish Growth Model : Four Essays on Capitalist Regulation and Institutional Change

    Författare :Viktor Skyrman; Handelshögskolan i Stockholm; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; The Regulation Approach; covered bonds; the forest industry; the financialization of nature; financial market institutionalization; European capital market integration; innovation system governance; spatio-temporal fixes; welfare state transformation; securitization; Business Administration;

    Sammanfattning : Financialization, the increasing influence of financial markets, actors, practices and measurements in political, economic and social life, continues to draw attention from scholars from diverse academic fields. Contributing to the literatures on household financialization, financial market institutionalization and the financialization of nature, this dissertation explores the underlying factors that enabled and facilitated the financialization of Sweden’s growth model.

  5. 4. Cattle Shipments and Disease Spread Modeling

    Författare :Peter Brommesson; Tom Lindström; Uno Wennergren; Angela Luis; Linköpings universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Spread of transboundary animal diseases can have large impact on animal welfare, public health and economy. The effects of this include economic losses in terms of lower milk production, lower weight gain and culling due to welfare concerns. LÄS MER

  7. 5. Bee foraging and pollination : Consequences of spatial and temporal variation in flower resources

    Författare :Johanna Yourstone; Biodiversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Apoidea; bumblebee; foraging behavior; landscape ecology; land-use change; oilseed rape; trees; flower constancy; honeybee competition; functional traits; seminatural habitats; chili;

    Sammanfattning : Wild bees foraging in contemporary agricultural landscapes are, because of agricultural intensification, faced with the challenges of reduced flower-rich habitats, as well as a changed spatio-temporal distribution of flower resources. As a result of this and other stressors such as pesticide exposure, widespread declines of bees have been reported. LÄS MER
