  1. 1. Rock Evaluation Using Digital Images and Drill Monitoring Data : Before and after rock blasting

    Author : Sohail Manzoor; Anna Gustafson; Håkan Schunnesson; Daniel Johansson; Philipp Hartlieb; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Measurement while drilling; Photogrammetry; Rock fragmentation; Gruv- och berganläggningsteknik; Mining and Rock Engineering;

    Abstract : This research is carried out to better understand the nature of the rock mass and to have a better anticipation of rock fragmentation before blasting the rock mass. Current practices of assessing rock mass usually involve techniques that focus on the surface or outcrop of the rock mass such as scanline surveys, window surveys, photogrammetry and laser scanning etc. READ MORE

  2. 2. Cryogenic soil processes in a changing climate

    Author : Marina Becher; Jonatan Klaminder; Johan Olofsson; Jan Karlsson; Niclas Börlin; Philip Wookey; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Non-sorted circle; Carbon storage; Soil motion; Terrestrial photogrammetry; Cryoturbation; Carbon fluxes; naturgeografi; Physical Geography;

    Abstract : A considerable part of the global pool of terrestrial carbon is stored in high latitude soils. In these soils, repeated cycles of freezing and thawing creates soil motion (cryoturbation) that in combination with other cryogenic disturbance processes may play a profound role in controlling the carbon balance of the arctic soil.

  3. 3. Self-calibration and direct georeferencing in terrestrial laser scanning

    Author : Yuriy Reshetyuk; Lars E. Sjöberg; Milan Horemuz; Hansjörg Kutterer; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; terrestrial laser scanning; self-calibration; direct georeferencing; error sources; Surveying; Lantmäteri;

    Abstract : An important step in data processing from terrestrial laser scanning (TLS) is georeferencing, i.e. transformation of the scanner data (point clouds) into a real world coordinate system, which is important for their integration with other geospatial data. READ MORE

  4. 4. Autonomous bridge inspection based on a generated digital model

    Author : Ali Mirzazade; Björn Täljsten; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggkonstruktion; Structural Engineering;

    Abstract : Railway owners manage geographically dispersed networks comprising major elements of ageing infrastructure that are very susceptible to natural hazards. Consequently, transport agencies must address maintenance issues to guarantee serviceability and safety. READ MORE
