  1. 6. Hydro-Mechanical Behaviour of a Pressurised Single Fracture: An In-situ Experiment

    Författare :Patrik Alm; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; hydro-mechanical behaviour; hydraulic field test; transmissivity; effective stress; aperture; fracture stiffness; fracture; slug test;

    Sammanfattning : Exploration of ground water resources, grouting, disposal of nuclear waste and extraction of geothermal energy are examples of activities which require consideration of the relationship between effective stress and transmissivity. However, this relationship is poorly understood and very few investigations have been conducted in field scale. LÄS MER

  3. 7. Nonlinear Numerical Simulations of Interactions Between Ice Rubble and Structure

    Författare :Aniket Patil; Andrzej Cwirzen; Björnar Sand; Lennart Fransson; Knut Vilhelm Høyland; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ice mechanics; ice rubble; sea ice ridges; punch through test; shear box test; friction coefficient; cohesive element method; smoothed particle hydrodynamics; continuous surface cap model; numerical modelling; Byggkonstruktion; Structural Engineering;

    Sammanfattning : This research is focused on three distinct but interconnecting topics:1) investigation of physical and mechanical properties of ice rubble, 2) material modelling of ice rubble, 3) numerical simulation of the interaction between ice rubble structure interaction. large scatter in the values of physical and mechanical properties of ice rubble can be seen in the literature due to non-standardised methods.

  4. 8. Genotoxic hazards in the rubber industry : application of short-term tests in work environment analyses

    Författare :Agneta Rannug; Stockholms universitet; []
    Nyckelord :;

    Sammanfattning : Excess mortality from a number of different types of cancer has been associated with work in the rubber industry. The aim of the present study - using short-term tests for mutagenicity - was to identify potentially hazardous additives and process fumes to which workers are exposed. LÄS MER

  5. 9. Wear resistant low friction coatings for engine components

    Författare :Per Lindholm; Sören Andersson; Rickard Larker; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering materials; cam; roller follower; carbon coating; engine test; finite element method; Konstruktionsmaterial; Construction materials; Konstruktionsmaterial;

    Sammanfattning : Engine development today is driven by cost, performance and government regulations. Customers want cars and trucks to consume less fuel, last longer, pollute less and be safer. Several of the requirements have tribological associations. For example, product longevity can be improved by lowering friction and using more wear-resistant components. LÄS MER

  7. 10. Haptic perception, attention, and effects on performance in a driving context : use of a haptic rotary device in a menu selection task

    Författare :Camilla Grane; Anita Fang Chen; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk psykologi; Engineering Psychology;

    Sammanfattning : In-vehicle driving interfaces have become increasingly complex with added secondary task functions designed to make driving enjoyable and comfortable. A single display solution in combination with a haptic rotary device has the potential to reduce the clutter of buttons. With well-designed haptic information (i.e. LÄS MER
