  2. 2. Terrain Modelling with GIS for Tectonic Geomorphology Numerical Methods and Applications

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Gyözö Jordan; Uppsala universitet.; [2004]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; digital elevation model; digital terrain modelling; GIS; morphometry; tectonic geomorphology; Miljöteknik; TECHNOLOGY Other technology Environmental engineering; TEKNIKVETENSKAP Övriga teknikvetenskaper Miljöteknik;

    Sammanfattning : Analysis of digital elevation models (DEMs) by means of geomorphometry provides means of recognising fractures and characterising the morphotectonics of an area in a quantitative way. The objective of the thesis is to develop numerical methods and a consistent GIS methodology for tectonic geomorphology and apply it to test sites. LÄS MER

  3. 3. Mesoscale Simulations of Atmospheric Flow in Complex Terrain

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Matthias Mohr; Uppsala universitet.; [2003]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Meteorology; Mesoscale modeling; Flow in complex terrain; Atmospheric dispersion; Model comparison; Boundary conditions; Numerical modeling; Atmospheric pressure; Gravity waves; Meteorologi; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences Meteorology; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap Meteorologi; Meteorology; meteorologi;

    Sammanfattning : The MIUU mesoscale model was further developed, in order to include information on large-scale atmospheric fields from global or regional atmospheric climate- and weather-prediction models. For this purpose, a new lateral boundary condition was developed and implemented into the model. LÄS MER

  4. 4. Modelling of six-wheeled electric transmission terrain vehicle

    Detta är en avhandling från Stockholm : KTH

    Författare :Olof Noréus; KTH.; [2007]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Engineering mechanics; TEKNIKVETENSKAP Teknisk mekanik;

    Sammanfattning : In vehicles with electric transmission and independent wheel stations, it is possible to have a possibility to control propulsion, steering and suspension individually for each wheel. This makes it possible to improve mobility, performance and driving safety. LÄS MER

  5. 5. Water quality modeling based on landscape analysis: importance of riparian hydrology

    Detta är en avhandling från Stockholm : Department of Physical Geography and Quaternary Geology, Stockholm University

    Författare :Thomas Grabs; Stockholms universitet.; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Water quality model; terrain analysis; geographical information system GIS; riparian zone; total organic carbon TOC; boreal catchments; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences Hydrology; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap Hydrologi; geografi med naturgeografisk inriktning; Physical Geography;

    Sammanfattning : Several studies in high-latitude catchments have demonstrated the importance of near-stream riparian zones as hydrogeochemical hotspots with a substantial influence on stream chemistry. An adequate representation of the spatial variability of riparian-zone processes and characteristics is the key for modeling spatio-temporal variations of stream-water quality. LÄS MER
