  1. 1. The accessibility paradox Everyday geographies of proximity, distance and mobility

    University dissertation from Umeå : Umeå universitet

    Author : Katarina Haugen; Umeå universitet.; [2012]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Accessibility; proximity; distance; daily mobility; everyday life; residential conditions; spatial structure;

    Abstract : This thesis aims to explore the importance of proximity and mobility, respectively, for individuals’ accessibility, as well as the relationship between these two key spatial dimensions of accessibility in the context of everyday life. The thesis is based upon three empirical research papers which focus on accessibility-related preferences, actual accessibility conditions, and travel patterns. READ MORE

  2. 2. Essays on Distance Based (Non-Euclidean) Tests for Spatial Clustering in Inhomogeneous Populations Adjusting for the Inhomogeneity through the Distance Used

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Ulla Romild; Uppsala universitet.; [2006]
    Keywords : Statistics; Clustering; Spatial Point Pattern; Inhomogeneous Density; Statistik;

    Abstract : This thesis consits of four papers dealing with distance based (non-Euclidean) tests for spatial clustering in inhomogeneous populations. The density adjusted distance (DAD), which considers the underlying density, is defined in the first paper. READ MORE

  3. 3. Spatial Spread of Organisms Modeling ecological and epidemiological processes

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Tom Lindström; Linköpings universitet.; Linköpings universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 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. 4. Spatial analysis and modeling of urban transportation networks
