  1. 1. Sustainable consumption for policymakers: measuring, learning and acting

    Författare :Elena Dawkins; Viveka Palm; Mattias Höjer; Åsa Persson; Paul Ekins; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sustainable consumption; environmental pressures; consumption-based indicators; footprint; policymaker; measuring; learning; action; Sweden; Planering och beslutsanalys; Planning and Decision Analysis;

    Sammanfattning : Current patterns and levels of consumption are a key driver of unsustainable resource use and pollution, which contributes to global environmental degradation. Rapid reductions in environmental pressures are required to avoid irreversible loss of fragile ecosystems and social and economic crises. Consumption must become sustainable. LÄS MER

  3. 2. Flow Measuring Techniques in Steady and Pulsating Compressible Flows

    Författare :Fredrik Laurantzon; Henrik Alfredsson; Björn Lindgren; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flow measuring; compressible flow; steady flow; pulsating flow; hot-wire anemometry; cold-wire anemometry; Engineering mechanics; Teknisk mekanik;

    Sammanfattning : This thesis deals with flow measuring techniques applied on steady and pulsatingflows. Specifically, it is focused on gas flows where density changes canbe significant, i.e. compressible flows. LÄS MER

  4. 3. Multidirectional Mobilities - Advanced Measurement Techniques and Applications

    Författare :Lars H. Ivarsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; R-DOFs; substructuring; measurement techniques; rotational mobility; multidirectional mechanical mobility; hybrid coupling; coupling; moment mobility; impedance coupling; consistency;

    Sammanfattning : Today high noise-and-vibration comfort has become a quality sign of products in sectors such as the automotive industry, aircraft, components, households and manufacturing. Consequently, already in the design phase of products, tools are required to predict the final vibration and noise levels. LÄS MER

  5. 4. Towards a new sensing strategy for measuring paper pulp properties : a combination of ultrasonic and optical measurement techniques

    Författare :Jan Niemi; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Electronics; Industriell elektronik;

    Sammanfattning : In the manufacturing process of paper the mass fraction and material properties of the fibres in the pulp suspension are important for the strength and quality of the finished product. The properties of the fibres in the pulp suspension that enters the paper machine is not well understood and therefore an adequate prediction of the strength and quality of the finished paper is not possible.
