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

    Författare :Jörgen Larsson; Fredrik Johansson; Alejano Leandro; KTH; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  5. 4. Förlorat järn : det medeltida jordbrukets behov och förbrukning av järn och stål

    Författare :Catarina Karlsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; HUMANIORA; HUMANITIES;

    Sammanfattning : Lost Iron – requirement and consumption of iron and steel in agriculture in medieval Sweden This study aims at an estimation of the amount of iron required for agriculture during the Middle Ages in Sweden. To calculate this we need to know which implements were used, their weights and how they were subjected to wear. LÄS MER

  7. 5. Towards Elastic High-Performance Geo-Distributed Storage in the Cloud

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

    Sammanfattning : 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. LÄS MER
