  2. 16. Spatial Variation in Near-Ground Radiation and Low Temperature - Interactions with Forest Vegetation

    Author : Kristina Blennow; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; light interception; hemispherical photograph; growth; forest fragmentation; fluorescence; cold-induced photoinhibition; GIS; view factor; radiative cooling; frost protection; agro-climatic mapping; forest clear-cut; local climate; Microclimate; Physical geography; geomorphology; pedology; cartography; climatology; Fysisk geografi; geomorfologi; marklära; kartografi; klimatologi;

    Abstract : Low temperature has a large impact on the survival and distribution of plants. Interactive effects with high irradiance lead to cold-induced photoinhibition, which may impact on the establishment and growth of tree seedlings. READ MORE

  4. 17. PRO-POOR PLANNING: A Tool for Strategic Territorial Planning and a Conceptual Framework Drawn from Studies in Colombia and Costa Rica

    Author : Carlos de la Espriella; Boende och bostadsutveckling; []
    Keywords : HUMANIORA; HUMANITIES; Poverty Reduction; Statistical Information; Social Housing; Urban Governance; Urbanization; Poverty Impact Assessments; Poverty Mapping; Local Authorities; Poverty; Integrated Urban Planning; Inequality; Geographic Information Systems; Decentralization; Costa Rica; Census Microdata; Colombia; Urban Residential Segregation; Urban Planning;

    Abstract : Few planning practices in the South seem to be equipped with key concepts and technical, empirical and administrative capacities required to comprehend and visualize the phenomenon of poverty at inter- and intra-urban levels, which compromises their ability to inform decision-makers on the effects on poverty reduction of the land-based actions they design, implement and monitor. This challenge was addressed from conceptual, technical, empirical, and administrative angles, which correspond to the research objectives. READ MORE

  5. 18. Distributed Technology-Sustained Pervasive Applications

    Author : Kim J.L. Nevelsteen; Theo Kanter; Rahim Rahmani; Kåre Synnes; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; pervasive; games; engine; distributed; virtual; world; internet of things; Computer and Systems Sciences; data- och systemvetenskap;

    Abstract : Technology-sustained pervasive games, contrary to technology-supported pervasive games, can be understood as computer games interfacing with the physical world. Pervasive games are known to make use of ‘non-standard input devices’ and with the rise of the Internet of Things (IoT), pervasive applications can be expected to move beyond games. READ MORE

  6. 19. Modelling, mapping and visualisation of flood inundation uncertainties

    Author : Nancy Joy Lim; Stefan Seipel; S. Anders Brandt; Eva A. U. Sahlin; Matthew Wilson; Högskolan i Gävle; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cartography; flood; hydraulic modelling; GIS; map; uncertainty; visualisation; GIS; hydraulisk modellering; karta; kartografi; osäkerhet; visualisering; översvämning; Hållbar stadsutveckling; Sustainable Urban Development;

    Abstract : Flood maps showing extents of predicted flooding for a given extreme event have wide usage in all types of spatial planning tasks, as well as serving as information material for the public. However, the production processes that these maps undergo (including the different data, methods, models and decisions from the persons generating them), which include both Geographic Information Systems (GIS) and hydraulic modelling, affect the map’s content, and will be reflected in the final map.

  7. 20. Spatial variability of geogenic contaminants in drinking water sources : Insights into hydrogeological controls, geospatial data for safe water supply and groundwater resource management

    Author : J. Ijumulana; Prosun Bhattacharya; Felix Mtalo; Steve W. Lyon; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Drinking water; geogenic contaminants; potentially toxic elements; fluoride; spatial analysis; spatial variability; Tanzania; Land and Water Resources Engineering; Mark- och vattenteknik;

    Abstract : The presence of geogenic contaminants in drinking water is a major health concern in many parts of the world. The interaction of groundwater with different rock types and sediments in the natural geochemical environment play an important role in controlling their mobility. READ MORE
