  1. 11. UNDERSTANDING URBAN PATTERNS Qualitative and Quantitative Approaches

    Detta är en avhandling från Institutionen för infrastruktur och samhällsplanering

    Författare :Vânia Aparecida Ceccato; KTH.; [2001]
    Nyckelord :urban quality; GIS; spatial statistics;

    Sammanfattning : In this thesis, the main field of study is urban patternsand the methodological issues involving the analysis of spatialdata across urban space. Four particular aspects are chosen toillustrate the dynamics of urban space, using Stockholm Countyas case study. LÄS MER

  2. 12. Tillgänglighet för personer med funktionsnedsättningar

    Detta är en avhandling från Institutionen för infrastruktur och samhällsplanering

    Författare :Johan Svensson; [2007]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; impairment; urban planning.; GIS; disability; accessibility; functional limitations;

    Sammanfattning : Since the design of our cities tends to constrain people with impairments from performing their daily activities, removing barriers and making public space accessible for everyone is becoming a human rights-issue. Due to an ageing population, the number of impaired citizens is expected to increase substantially over the next 50 years. LÄS MER

  3. 13. Spatial Variation in Near-Ground Radiation and Low Temperature - Interactions with Forest Vegetation

    Detta är en avhandling från Lund University Press

    Författare :Kristina Blennow; [1997]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 14. Visualization, integration and analysis of multi-element geochemical data

    Detta är en avhandling från Stockholm : KTH

    Författare :Katrin Grünfeld; KTH.; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; GIS; interactive visualization; glacial till; biogeochemistry; metals; southeastern Sweden; Geovetenskap; NATURAL SCIENCES Earth sciences; NATURVETENSKAP Geovetenskap;

    Sammanfattning : generated large databases containing information on the concentrations of chemical elements in rocks, surface sediments and biogeochemical materials. Regional geochemical data being imprecise, multivariate, spatially auto-correlated and non-normally distributed pose specific problems to the choice of data analysis methods. LÄS MER

  5. 15. EstimatingChloride concentration in surface water and groundwater duet to deicing salt application

    Detta är en avhandling från Stockholm : Mark och vatten

    Författare :Eva-Lotta Thunqvist; KTH.; [2003]
    Nyckelord :road; deicing salt; monitoring; chloride; catchment area; river basin; simulation; GIS; groundwater; surface water;

    Sammanfattning : A road in operation along with its traffic can pose aserious pollutant threat to groundwater and surface water inits vicinity. Examples of pollutants are metals from thecorrosion of vehicles, rails and poles and the wear of roadsurfaces and tyres; hydrocarbons from the wear of roadsurfaces, tyres, exhausts, oils; sodium chloride from roadsalt; and hazardous goods discharged in accidents.
