  2. 1. Towards Realistic Visualisation of Production Systems

    Author : Erik Lindskog; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Realistic visualisation; Manufacturing systems; 3D laser scanning; Point clouds; Production systems;

    Abstract : Redesigning a production system is a complex process for which numerous virtual tools are available to support the planning process. These virtual tools are used to forecast and analyse the production system prior to implementing the redesign, which makes it possible to identify and prevent costly problems during the planning process.

  4. 2. A Framework for Systematic use of Realistic Visualisation to Support Layout Planning of Production Systems

    Author : Erik Lindskog; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; layout planning; visualisation; manufacturing systems; point clouds; production systems; 3D laser scanning;

    Abstract : The process of designing production systems comprises a sequence of steps toward the final design and realisation. Layout planning is a significant part of this process. Its outcome should be a layout which matches the existing spatial conditions of the factory building and desired performance of the production system. READ MORE

  5. 3. Rock damage caused by underground excavation and meteorite impacts

    Author : Ann Bäckström; Robert Zimmerman; John A Hudson; Flavio Lanaro; Pekka Särkkä; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Excavation Damage Zone EDZ ; Fracture analysis; Pre-existing fractures; Class II behaviour; 3D laser scanning; Impact fracturing; Geoengineering; Geoteknik;

    Abstract : The intent of this thesis is to contribute to the understanding of the origin of fractures in rock. The man-made fracturing from engineering activities in crystalline rock as well as the fracturing induced by the natural process of meteorite impacts is studied by means of various characterization methods.

  6. 4. Static and time-dependent mechanical behaviour of preserved archaeological wood : Case studies of the seventeenth century warship Vasa

    Author : Alexey Vorobyev; Kristofer Gamstedt; Eiichi Obataya; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; archaeological wood; compression test; cubic samples; elastic constants; oak wood; barrelling formation; quasi-static loading; resonant ultrasound spectroscopy RUS ; Vasa ship; creep; 3D laser scanning; Time-dependent behaviour;

    Abstract : Wooden objects have been widely used in the history of humanity and play an important role in our cultural heritage. The preservation of such objects is of great importance and can be a challenging task. This thesis investigates the static and time-dependent mechanical behaviour of archaeological oak wood from the Vasa warship. READ MORE
