  1. 1. Simulations

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Henrik Svensson; Linköpings universitet.; Linköpings universitet.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis is concerned with explanations of embodied cognition as internal simulation. The hypothesis is that several cognitive processes can be explained in terms of predictive chains of simulated perceptions and actions. READ MORE

  2. 2. Weld Pool Simulations

    University dissertation from Göteborg : Department of Mathematical Sciences

    Author : Marcus Edstorp; Chalmers tekniska högskola Göteborgs universitet.; Chalmers University of Technology University of Gothenburg.; Chalmers tekniska högskola Göteborgs universitet.; Högskolan Väst.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tillämpad matematik; Applied mathematics; Produktionsteknik; Manufacturing engineering; Övrig bearbetning sammanfogning; Other processing assembly; Arc Welding; Weld Pool; Multiphysics Simulations; Moving Boundaries; Free Surfaces; Mesh Motion; Two-Phase Flow; Incompressible Flow; Electromagnetics; Finite Element Methods; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : This investigation is devoted to the study of welding and its effect on the workpiece, focusing on the thermo and fluid dynamical phenomena occuring during a autogenous or nonautogenous arc fusion welding process. Its aim is to simulate the behaviour of the weld pool and analyze the consequence of the solid-liquid phase change, thus obtaining a methodology for predicting the appearance of weld defects related to solidification and cooling.

  3. 3. Fluid Mechanics of Vertical Axis Turbines Simulations and Model Development

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Anders Goude; Uppsala universitet.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wind power; Marine current power; Vertical axis turbine; Wind farm; Channel flow; Simulations; Vortex model; Streamtube model; Control system; Graphics processing unit; CUDA; Fast multipole method; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : Two computationally fast fluid mechanical models for vertical axis turbines are the streamtube and the vortex model. The streamtube model is the fastest, allowing three-dimensional modeling of the turbine, but lacks a proper time-dependent description of the flow through the turbine. READ MORE

  4. 4. Situating Simulators : The integration of simulations in medical practice

    University dissertation from Lund : Arkiv förlag

    Author : Ericka Johnson; Linköpings universitet.; Linköpings universitet.; [2004]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; reconstitution; medical simulators; simulations; situated learning; medical practice; apprenticeship; legitimate peripheral participation; intra-action; agency; medicinsk utbildning; simulering; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Abstract : This study examined the practices of integrating simulators into medical education. Simulators have been observed in use to discern how medical practices are created out of the simulations. Video recordings of the simulations have been analysed, complemented by interviews with instructors and students. READ MORE
