  2. 1. Spatial Spread of Organisms : Modeling ecological and epidemiological processes

    Author : Tom Lindström; Uno Wennergren; Colleen Webb; Linköpings universitet; []
    Keywords : Spatial kernel; Spatially explicit modeling; Disease transmission; Animal movements; NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : This thesis focuses on the spread of organisms in both ecological and epidemiological contexts. In most of the studies presented, displacement is modeled with a spatial kernel function, which is characterized by scale and shape. These are measured by the net squared displacement (or kernel variance) and kurtosis, respectively. READ MORE

  4. 2. Visual Flow Display for Pilot Spatial Orientation

    Author : Lars Eriksson; Claes von Hofsten; David Lee; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Optic flow; visual flow; peripheral vision; spatial orientation; spatial disorientation; postural control; somatogravic illusion; human centrifuge; flight displays; head-up display; head-mounted display; Psychology; Psykologi; Psychology; psykologi; Psykologi;

    Abstract : Pilot spatial disorientation (SD) is a significant cause of incidents and fatal accidents in aviation. The pilot is susceptible to SD especially in low visibility when the visual system is deprived of information from outside the cockpit. READ MORE

  5. 3. The spatial manifestation of inequality : residential segregation in Sweden and its causes

    Author : Simone Scarpa; Tapio Salonen; Susanne Urban; Lars Brännström; Linnéuniversitetet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; residential segregation; income inequality; immigration; immigration policy regime; welfare state; housing; Sweden; Malmö; Genoa; Swedish metropolitan areas; Sociology; Sociologi; Socialt arbete; Social Work; Human Geography; Kulturgeografi;

    Abstract : The thesis examines the relationship between income inequality and residential segregation in Swedish cities. In recent years, in Sweden, much attention has been given to the direction of causality from residential segregation to income inequality. READ MORE

  6. 4. Dynamics of ecological communities in variable environments : local and spatial processes

    Author : Linda Kaneryd; Bo Ebenman; Peter Münger; Michael S. Fowler; Linköpings universitet; []
    Keywords : ;

    Abstract : The ecosystems of the world are currently facing a variety of anthropogenic perturbations, such as climate change, fragmentation and destruction of habitat, overexploitation of natural resources and invasions of alien species. How the ecosystems will be affected is not only dependent on the direct effects of the perturbations on individual species but also on the trophic structure and interaction patterns of the ecological community.

  7. 5. Multi-robot Information Fusion : Considering spatial uncertainty models

    Author : Lars Andersson; Karl-Erik Rydberg; Aarne Halme; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The work presented in this thesis covers the topic of deployment for mobile robot teams. By connecting robots in teams they can perform a better job than each individual is capable of. It also gives redundancy, increases robustness, provides scalability, and increases efficiency. READ MORE
