  1. 6. Swash Processes and Dune Erosion: Emphasis on Vessel-Generated Waves

    Författare :Li Erikson; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; marklära; kartografi; klimatologi; Civil engineering; hydraulic engineering; geomorfologi; Fysisk geografi; climatology; cartography; pedology; geomorphology; Naturvetenskap; Physical geography; Natural science; swash; erosion; vessel-generated waves; dunes; offshore technology; soil mechanics; Väg- och vattenbyggnadsteknik;

    Sammanfattning : In navigable waterways, owing to the relatively short fetches for wind wave generation, the free waves generated by moving vessels often produce the dominant wave action with respect to erosion of the shore. In response to the fairly recent introduction of high-speed ferries, combined with a planned expansion within the passenger- and car-carrying ship market, the need to model and predict coastline changes as a result of exposure to vessel-generated waves has become a topic of increased research.

  3. 7. Geometallurgy of a complex ore : Lappberget Zn-Pb-Ag-(Cu-Au) deposit, Garpenberg mine, Sweden

    Författare :Glacialle Tiu; Christina Wanhainen; Yousef Ghorbani; Nils Jansson; Jens Gutzmer; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ore Geology; Malmgeologi;

    Sammanfattning : Complex ores, in this instance, a polymetallic base metal ore with additional precious and penalty elements, pose particularly tough challenges for successful production forecasts. Plant performance and recoveries for complex ores are more difficult to predict due to the larger number of variables that must be considered, tracked, and characterized during the multi-stage separation process.

  4. 8. Strength variability in lime-cement columns and its effect on the reliability of embankments

    Författare :Mohammed Salim Al-Naqshabandy; Stefan Larsson; Lars Olsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lime-cement; embankments;

    Sammanfattning : Ground improvement by deep mixing (DM) is a generic term used for a number of methods in which a binding agent, often lime and/or cement, is mechanically mixed with the soil to increase its engineering properties. The inherent variability with respect to the engineering properties of the improved soil is high due to the variations in geology and the complex mixing process. LÄS MER

  7. 10. Excavation damage from blasting with emulsion explosives : Quality control and macro fracturing in the remaining rock

    Författare :Henrik Ittner; Håkan Schunnesson; Daniel Johansson; Radoslava Ivanova; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gruv- och Berganläggningsteknik; Mining and Rock Engineering;

    Sammanfattning : Excavation damage is usually regulated in Swedish infrastructure tunnel contracts as it can influence the quality and lifecycle cost for tunneling projects. The topic is important for underground constructions with a long operation period such as tunnels for public transport, permanent access tunnels in mines or underground repositories for nuclear waste.
