  1. 1. Flexible culverts in sloping terrain Research advances and application

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Amer Wadi; KTH.; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flexible culvert; Soil‒steel composite bridge; Sloping terrain; Swedish design method; Finite element model; Slope stability; Avalanche load; Snowshed; Civil and Architectural Engineering; Byggvetenskap;

    Sammanfattning : Although the construction of flexible culverts involves simplicity in comparison to similar concrete structures, the complexity of the beneficial interaction between soil and steel materials requires good understanding for their composite action and performance. Current design methods have certain validity limitations with regard to applicable slopes above the structures. LÄS MER

  2. 2. Terrain Object recognition and Context Fusion for Decision Support

    Detta är en avhandling från Institutionen för datavetenskap

    Författare :Fredrik Lantz; Linköpings universitet.; Linköpings universitet.; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nformation Fusion; Terrain Elevation Model; Driveability; Context Fusion; Terrain Object Recognition; TECHNOLOGY Information technology Computer science Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap Datalogi;

    Sammanfattning : A laser radar can be used to generate 3D data about the terrain in a very high resolution. The development of new support technologies to analyze these data is critical to the effective and efficient use of these data in decision support systems, due to the large amounts of data that are generated.

  3. 3. Glacial dynamics and till genesis in hilly terrain A study in the Tallträsk area, central-northern Sweden

    Detta är en avhandling från Umeå : Ekologi, miljö och geovetenskap

    Författare :Hans Ivarsson; Umeå universitet.; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; till analyses; glacial stratigraphy; subglacial deposition; deglaciation; hilly terrain; northern Sweden; NATURAL SCIENCES Earth sciences Exogenous earth sciences Physical geography; NATURVETENSKAP Geovetenskap Exogen geovetenskap Naturgeografi;

    Sammanfattning : This study deals with the influence of topography on glacial dynamics and the genesis of till in an area of moder-ate bedrock relief. An area 25 km west of Lycksele, northern Sweden, was investigated using geomorphological and sedimentological methods. LÄS MER

  4. 4. 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

  5. 5. Bayesian Inference in Terrain Navigation

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Niclas Bergman; Linköpings universitet.; Linköpings universitet.; [1997]

    Sammanfattning : Terrain navigation is a concept for autonomous aircraft navigation. If measurements of the terrain height over mean sea-level are collected along the aircraft flight path, an estimate of the aircraft position can be formed by matching these measurements with a digital reference terrain map. This matching is a recursive nonlinear estimation problem. LÄS MER
