  1. 1. Multiscale methods for simulation of paper making

    Author : Gustav Kettil; Chalmers tekniska högskola; []
    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.

  2. 2. Making Pairs

    Author : Jens Gudmundsson; Nationalekonomiska institutionen; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; equilibrium; existence; Pairing; matching; stability; algorithms;

    Abstract : This thesis makes a contribution to matching theory. It consists of five self-contained papers. It is a study predominately on the existence of stable outcomes. These are desirable both from a practical and a theoretical standpoint. READ MORE

  3. 3. Making Futures : On Targets, Measures and Governance in Backcasting and Planning

    Author : Josefin Wangel; Örjan Svane; Lars Nilsson; KTH; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; futures studies; backcasting; planning; governance; sustainable development;

    Abstract : This thesis is about the making of futures – in the sense of planning, through which the world of tomorrow is crafted, and in the sense of images of the future, developed through the futures studies approach of backcasting. The point of departure for the thesis is that more visionary and strategic forms of planning are needed if the challenges of sustainable development are to be met, and that backcasting, through its long-term, integrative and normative character, can be a helpful tool towards this end.

  4. 4. Making waves : A study of the patterns and consequences of non-state actor participation in global fisheries governance

    Author : Matilda Petersson; Henrik Österblom; Lisa Dellmuth; Robert Blasiak; Megan Bailey; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Global fisheries governance; regional fisheries management organizations RFMOs ; non-state actors; non-governmental organizations NGOs ; transnational partnerships; participation; influence; effectiveness; process tracing; Sustainability Science; vetenskap om hållbar utveckling;

    Abstract : States have established regional fisheries management organizations (RFMOs) to manage transboundary fish stocks. However, the effectiveness of these bodies has been questioned. Problems with overfishing, illegal, unreported, and unregulated (IUU) fishing, and bycatch remain persistent and difficult to solve. READ MORE

  5. 5. Dimensional Stability of Paper : Influence of Fibre-Fibre Joints and Fibre Wall Oxidation

    Author : Per A. Larsson; Lars Wågberg; Mikael Lindström; Lars Berglund; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Abstract : Papper är ett mycket mångsidigt material. Trots detta finns det ett flertal egenskaper som begränsar papperets användbarhet. Ett av de större problemen med cellulosa- och lignocellulosafibrer är att de sänker sin fria energi genom att sorbera vatten, och denna sorption förändrar papperets dimensioner. READ MORE
