  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. 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

  3. 3. Weld Pool Simulations

    University dissertation from Göteborg

    Author : Marcus Edstorp; Göteborgs universitet.; Gothenburg University.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Arc Welding; Weld Pool; Multiphysics Simulations; Moving Boundaries; Free Surfaces; Mesh Motion; Two-Phase Flow; Incompressible Flow; Electromagnetics; Finite Element Methods;

    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.

  5. 5. Low Frequency Impact Sound in Timber Buildings Transmission Measurements and Simulations

    University dissertation from Växjö : Linnaeus University Press

    Author : Jörgen Olsson; Linnéuniversitetet.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Byggteknik; Civil engineering; Timber floors; FE-simulations; Light weight floors; Frequency response functions; Building acoustics;

    Abstract : An increased share of multi-story buildings that have timber structures entails potential in terms of increased sustainability as well as human-friendly manufacturing and habitation. Timber buildings taller than two stories were prohibited in Europe until the 1990s due to fire regulations. In 1994, this prohibition was removed in Sweden. READ MORE
