  2. 21. Potential Use of Aquifer Thermal Energy Storage System in Arid Regions

    Author : Qais Al-Madhlom; Jan Laue; Nadhir Al-Ansari; Sabbar Abdullah Saleh; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aquifer thermal energy storage system; ATES; site selection; seepage velocity; aquifer vulnerability; DRASTIC; arid regions; ArcMap GIS; Soil Mechanics; Geoteknik;

    Abstract : After the Oil Crises in 1973, which meant higher energy costs, the world started to look for other sources of energy. This led to the development of renewable energy techniques. Because of the intermittent nature of renewable energy, storage systems were also developed. READ MORE

  4. 22. Recycling of green liquor dregs in cover application on acid generating mine waste

    Author : Susanne Nigéus; Jan Laue; Christian Maurice; Jenny Lindblom; Helge Hellevang; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geoteknik; Soil Mechanics;

    Abstract : The mining industry generates massive amounts of waste that without treatment and in contact with atmospheric oxygen can cause the formation of acid rock drainage (ARD). In Sweden, the most common reclamation measure for mine waste is to apply a multi-layer cover on top of the waste deposit. READ MORE

  5. 23. Geotechnical risk management using the observational method

    Author : Mats Tidlund; Stefan Larsson; Johan Spross; Håkan Stille; Jan Bröchner; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; risk; risk management; geotechnical engineering; contractual framework; observational method; risk; riskhantering; geoteknik; kontrakt; observationsmetoden; Soil and Rock Mechanics; Jord- och bergmekanik;

    Abstract : There have been many cost overruns, time delays and quality problems reported from geotechnical engineering projects around the world during recent decades. Many of the reported problems are associated with risks related to the geotechnical conditions. READ MORE

  6. 24. Discrete element technique for modeling high-speed railway tracks

    Author : Alireza Ahmadi; Stefan Larsson; Carl Wersäll; Liang Cui; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polygonal particles; Direct shear test; Particle scaling; Bal- lasted track; DEM; Polygonala partiklar; direkt skjuvförsök; partikelskalning; ballastspår; DEM; Soil and Rock Mechanics; Jord- och bergmekanik;

    Abstract : The Discrete element method (DEM) is a methodology to investigatethe interactions among granular materials. It analyzes the behavior of par-ticulate environments by solving force-displacement equations that adhereto Newton’s second law of motion. READ MORE

  7. 25. In-situ and laboratory stress investigations using borehole data from the North Atlantic Ocean

    Author : Maria Ask; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

    Abstract : This doctoral thesis presents results from investigations ofin-situ and laboratory stress from borehole logging andlaboratory deformation experiments on drill-cores. The datacome from hydrocarbon exploration and production wells in theDanish Sector of the North Sea, and from boreholes drilled bythe Ocean Drilling Program (ODP). READ MORE
