  1. 21. Distributed Technology-Sustained Pervasive Applications

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

    Sammanfattning : 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. LÄS MER

  3. 22. Modelling, mapping and visualisation of flood inundation uncertainties

    Författare :Nancy Joy Lim; Stefan Seipel; S. Anders Brandt; Eva A. U. Sahlin; Matthew Wilson; Högskolan i Gävle; []
    Nyckelord :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;

    Sammanfattning : 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.

  4. 23. Att sätta barn på kartan : barnkartor i GIS – för information om barns utemiljö

    Författare :Kerstin Nordin; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : Utemiljön utgör en viktig del i många barns liv och FN:s konvention om barnets rättigheter ger barn rätt att höras i frågor som rör dem. Men ett flertal studier visar att det trots ett uttalat intresse hos många politiker och planerare är svårt att få frågor som berör barns utemiljö beaktade i kommunal, fysisk planering. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  7. 25. An Analysis of Consequences of Land Evaluation and Path Optimization

    Författare :Rachel Mundeli Murekatete; Takeshi Shirabe; Gerhard Navratil; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Least-cost paths; Most-suitable paths; Raster cost surfaces; Raster suitability surfaces; Shortest path problem; Minimax path problem; Scales of measurement; Minsta-kostnad rutter; Mest-lämpliga rutter; Raster kostnadsytor; Raster lämplighets ytor; kortaste vägen problem; Minimax väg problem; Mätskalor; Geodesy and Geoinformatics; Geodesi och geoinformatik;

    Sammanfattning : Planners who are involved in locational decision making often use raster-based geographic information systems (GIS) to quantify the value of land in terms of suitability or cost for a certain use. From a computational point of view, this process can be seen as a transformation of one or more sets of values associated with a grid of cells into another set of such values through a function reflecting one or more criteria.
