1. 1. Terrain machine learning

   Författare :Viktor Wiberg; Martin Servin; Tomas Nordfjell; Eddie Wadbro; Todor Stoyanov; Umeå universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; multibody dynamics simulation; rough terrain vehicle; autonomous vehicles; robotics control; discrete element method; sim-to-real; reinforcement learning; fysik; Physics;

   Sammanfattning : The use of heavy vehicles in rough terrain is vital in the industry but has negative implications for the climate and ecosystem. In addition, the demand for improved efficiency underscores the need to enhance these vehicles' navigation capabilities. LÄS MER

3. 2. Flexible culverts in sloping terrain : Research advances and application

   Författare :Amer Wadi; Raid Karoumi; Lars Pettersson; Jan Vaslestad; KTH; []
   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; Byggvetenskap; Civil and Architectural Engineering;

   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

4. 3. Terrain Object recognition and Context Fusion for Decision Support

   Författare :Fredrik Lantz; Erland Jungert; Per Svensson; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Information Fusion; Terrain Elevation Model; Driveability; Context Fusion; Terrain Object Recognition; Computer science; 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.

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

   Författare :Hans Ivarsson; Mats Jansson; Per Möller; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; till analyses; glacial stratigraphy; subglacial deposition; deglaciation; hilly terrain; northern Sweden; Physical geography; 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

7. 5. Terrain Modelling with GIS for Tectonic Geomorphology : Numerical Methods and Applications

   Författare :Gyözö Jordan; Ulf Qvarfort; Tsehaie Woldai; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; digital elevation model; digital terrain modelling; GIS; morphometry; tectonic geomorphology; Miljöteknik; Environmental engineering; 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
