  1. 1. Sound for Multisensory Motion Simulators

    Författare :Alexander Väljamäe; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; auditory scene synthesis; spatial audio; presence; virtual reality; cognitive acoustics; illusory self-motion; vection ; multisensory optimization;

    Sammanfattning : Interaction in a virtual reality environment often implies situations of illusory self-motion, like, for example, in flight or driving scenarios. Striving for pictorial realism, currently available motion simulators often exhibit relatively poor sound design. LÄS MER

  3. 2. Self-motion and Presence in the Perceptual Optimization of a Multisensory Virtual Reality Environment

    Författare :Alexander Väljamäe; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Determining the perceptually optimal resolution of multisensory renderingmight help to foster the development of cost-effective, highly immersivemulti-modal displays for mediated environments (e.g. virtual and augmentedreality). LÄS MER

  4. 3. A study of heat transfer from cylinders in turbulent flows by using thermochromic liquid crystals

    Författare :Roland Wiberg; KTH; []
    Nyckelord :Fluid mechanics; convection heat transfer;

    Sammanfattning : In gas quenching, metal parts are rapidly cooled from hightemperatures, and the convection heat transfer coefficientdistributions are of importance for the hardness and thedistortion (the shape nonuniformities) of the quenched parts.Thermochromic liquid crystals (TLC) and a thin foil techniques,were investi- gated and used for studies of a circular cylinderin axial flows, affected and not affected by upstream owmodifying inserts.

  5. 4. On the Arbitrary Lagrangian-Eulerian Finite Element Method

    Författare :Lars Olovsson; Kenneth Runesson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; large deformation plasticity; FEM; ALE; multi-material Euler; machining simulations;

    Sammanfattning : This thesis has been devoted to the study and development of algorithms for Finite Element (FE) simulations of mechanical processes involving large deformations. Aspects of three different formulations have been considered:(i) The single material Arbitrary Lagrangian-Eulerian (ALE) formulation is a method where the FE mesh is allowed to move independently to the material flow.

  7. 5. Explicit algebraic turbulence modelling in buoyancy-affected shear flows

    Författare :Werner Lazeroms; Arne Johansson; Antti Hellsten; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Turbulent flows affected by buoyancy forces occur in a large amount of applica-tions, from heat transfer in industrial settings to the effects of stratification inEarth’s atmosphere. The two-way coupling between the Reynolds stresses andthe turbulent heat flux present in these flows poses a challenge in the searchfor an appropriate turbulence model. LÄS MER
