  1. 1. Relationen styrning och utvärdering : Hur en europeisk utvärderingsidé översätts i Sverige

    Författare :Kettil Nordesjö; Verner Denvall; Per Mickwitz; Linnéuniversitetet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Governance; translation; framing; steering logics; Cohesion policy; European Union; institutional logics; participatory evaluation;

    Sammanfattning : Evaluation is an institutionalized practice in the western public sector with several applications and uses. At the same time, the effectiveness and use of evaluation is seldom demonstrated. This evaluation paradox is due to the fact that evaluation is constrained and shaped in relation to, among others, a political context. LÄS MER

  3. 2. A Novel Fiber Interaction Method for Simulation of Early Paper Forming

    Författare :Gustav Kettil; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fiber suspension flow model; object-object interaction model; contact forces; lay down simulations; paper forming; immersed boundary methods; contact forces;

    Sammanfattning : In the forming section of a paper machine, a fiber suspension is flowing down onto a forming fabric, and a paper structure is formed. By using computer simulations this process can be studied, attaining new knowledge helping to improve paper quality and machine efficiency. LÄS MER

  4. 3. Multiscale methods for simulation of paper making

    Författare :Gustav Kettil; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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. 4. Adaptive structural design - Integration of computational tools for CAD, adaptive FEM and optimization

    Författare :Per Kettil; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adaptive; structural mechanics; optimization; integration; FEM; CAD; design;

    Sammanfattning : BackgroundConstruction is one of the largest industries with major impact on economy, environment and society. Improved structural design is important since the decisions made during the design process strongly influence all later stages, i.e. LÄS MER

  7. 5. Computational Engineering Development and Implementation of Computational Methods for Structural Analysis and Design

    Författare :Per Kettil; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CAD; simulation; FEM; optimisation; integration; modelling; object-oriented;

    Sammanfattning : 'Computational engineering' (CE) is computation based on mathematical models for use in engineering design. CE can be used to study and optimise structures and processes in industry and other branches of society to utilise resources in the most effective way. Modelling, simulation, optimisation and visualisation are basic methods of CE. LÄS MER
