  2. 1. Quality aspects in direct shear testing of rock joints

    Author : Jörgen Larsson; Fredrik Johansson; Alejano Leandro; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rock joints; geometrical quality assurance; replicas; direct shear testing; normal stiffness; bergssprickor; geometrisk kvalitetssäkring; replikor; skjuvhållfasthetprovning; normalstyvhet.; Jord- och bergmekanik; Soil and Rock Mechanics;

    Abstract : The stability of rock masses is influenced by the occurrence of rock joints. Therefore, the shear strength of rock joints must be considered in dimensioning of underground constructions. READ MORE

  4. 2. Mechanical and Hydromechanical Behaviour of Hard Rock Joints. A laboratory study

    Author : Roger Olsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; laboratory shear tests; constant normal stiffness; rock mechanics; hydromechanical behaivour; rock joints; replicas;

    Abstract : As a consequence of rock engineering works, the rock mass will deform due to stress changes. Most deformation occurs in the rock joints, in form of normal and shear strains. These deformations will also change the void geometry and thereby the joint aperture and fluid flow. READ MORE

  5. 3. Virtual three-dimensional analysis of digitized dental impressions and stone replicas

    Author : Anna Persson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Accuracy; alignment software; computer-aided analysis; computer-aided design; computer-aided manufacturing; fixed prosthodontics; precision; reliability; reproducibility; surface digitization devices;

    Abstract : In response to increasing patient awareness of esthetic dental rehabilitation, the preference today is for all-ceramic restorations, which show superior biocompatibility and similar light characteristics to the natural tooth. The fit of a dental restoration depends on quality throughout the entire manufacturing process. READ MORE

  6. 4. Towards Elastic High-Performance Geo-Distributed Storage in the Cloud

    Author : Ying Liu; Vladimir Vlassov; Peter Van Roy; Jim Dowling; Seif Haridi; Gregory Chockler; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : In this thesis, we have presented techniques and algorithms to reduce request latency of distributed storage services that are deployed geographically. In addition, we have proposed and designed elasticity controllers to maintain predictable performance of distributed storage systems under dynamic workloads and platform uncertainties. READ MORE

  7. 5. Few particle effects in pyramidal quantum dots - a spectroscopic study

    Author : Daniel Dufåker; Fredrik Karlsson; Per Olof Holtz; Val Zwiller; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In this thesis two very similar processes have been studied, both involving excitations of particles during recombination of exciton complexes in quantum dots, reducing the energy of the emitted photon. Different exciton complexes are defined according to the number of electrons and holes in the quantum dot upon recombination. READ MORE
