    University dissertation from Karlskrona : Blekinge Institute of Technology

    Author : Maria Bäcke; Blekinge Tekniska Högskola.; [2011]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; HUMANIORA; HUMANITIES; power; digital games; online world; Second Life; virtuality; reality; role-play; hierarchy; authority; governing; subversion; performance; online worlds; virtual worlds; virtual; digital space; rules; hierarchies; negotiation; make-believe;

    Abstract : This study investigates how the members of four different role-playing communities on the online platform Second Life perform social as well as dramatic roles within their community. The trajectories of power influencing these roles are my main focus. READ MORE

  2. 2. Numerical Study of Fluid-Structure Interaction with Application to Oscillating Cylinders

    University dissertation from Mikhail Lazarkov, Magistratsvagen F55, 204, Lund

    Author : Mikhail Lazarkov; Lund University.; Lunds universitet.; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lock-in.; Thermal engineering; applied thermodynamics; Termisk teknik; termodynamik; synchronization; flow-induced vibration; LES; Volume of Solid method; Virtual Boundary method; vortex-shedding; confined cylinder; Fluid-structure interaction; wake;

    Abstract : The problem of fluid-structure interaction, occurring in many industrial and engineering applications, are of great importance, since interaction of a flow and a structure in it can lead to serious damages of the structure. The fluid-structure interaction gives rise to a variety of different physical phenomena such as flow-induced vibration, noise generation, etc. READ MORE

  3. 3. Simulations of turbulent boundary layers with suction and pressure gradients

    University dissertation from KTH Royal Institute of Technology

    Author : Alexandra Bobke; KTH.; KTH.; KTH.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; boundary layers; near-wall turbulence; history effects; asymptotic suction boundary layers; large-eddy simulation;

    Abstract : The focus of the present licentiate thesis is on the effect of suction and pressure gradients on turbulent boundary-layer flows, which are investigated separately through performing numerical simulations.The first part aims at assessing history and development effects on adverse pressure-gradient (APG) turbulent boundary layers (TBL).

  4. 4. Multiscale methods for simulation of paper making

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Gustav Kettil; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Paper making; Numerical upscaling; Lay down simulations; Virtual paper sheets; Fiber network model; Forming fabric flow; Fiber suspension flow; Fiber-fiber interaction; Multiscale methods; Fluid structure interaction;

    Abstract : In this work, multiscale methods for simulation of paper making are developed. The emphasis is on simulation of the paper forming process and simulation of the mechanical properties of paper sheets. To simulate paper forming, a novel fiber-fiber interaction method is proposed.

  5. 5. Influence of microstructure on debonding at the fiber/matrix interface in fiber-reinforced polymers under tensile loading

    University dissertation from Luleå : Luleå University of Technology

    Author : Luca Di Stasio; Luleå tekniska universitet.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fiber matrix interface; Debonding; Polymer-Matrix Composites PMC ; Finite Element Method FEM ; Linear Elastic Fracture Mechanics LEFM ; Polymeric Composite Materials; Polymera kompositmaterial;

    Abstract : At the end of the second decade of the XXI century, the transportation industry at large faces several challenges that will shape its evolution in the next decade and beyond. The first such challenge is the increasing public awareness and governmental action on climate change, which are increasing the pressure on the industrial sectors responsible for the greatest share of emissions, the transportation industry being one of them, to reduce their environmental footprint.
