  1. 11. Expansion Governance of the Integrated North Seas Offshore Grid

    Författare :João Gorenstein Dedecca; Paulien M. Herder; Rudi A. Hakvoort; Amineh Ghorbani; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Union; expansion planning; governance; HVDC; myopic optimization; North Seas; offshore grid; offshore wind; simulation;

    Sammanfattning : The expansion of offshore power transmission and generation in the North Seas of Europe is accelerating rapidly. This is due to several drivers, including the decarbonization and reform of the European power system, and innovations in offshore wind and high-voltage direct current transmission. LÄS MER

  2. 12. A Wave Expansion Method for Aeroacoustic Propagation

    Författare :Johan Hammar; Gunilla Efraimsson; Ciarán J. O'Reilly; Wim De Roeck; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sound propagation; Sound generation; Aeroacoustics; Aerodynamics; Computational fluid dynamics; Computational aeroacoustics; Numerical methods; Lighthill; Curle; Ffowcs Williams and Hawkings; Frequency-domain propagation; Wave expansion method.; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : Although it is possible to directly solve an entire flow-acoustics problem in one computation, this approach remains prohibitively large in terms of the computational resource required for most practical applications. Aeroacoustic problems are therefore usually split into two parts; one consisting of the source computation and one of the source propagation. LÄS MER

  3. 13. Flow, expansion and processing behaviours of gas-containing filled polyethylene

    Författare :Nabil Khoshaba; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mechanical properties; flow rate; critical pressure; injection moulding; expansion kinetics; fillers; rheological properties; foaming; composite materials; partial pressure; capillary viscometry; Blowing agent;

    Sammanfattning : The utilization of fillers in polymeric materials has exhibited a substantial growth during the last decades. Chalk (calcium carbonate) and glass fibres are two common examples of such fillers. These fillers/reinforcing elements are used in order to reduce the cost of material and change its physical (mechanical) properties. LÄS MER

  4. 14. Hygro-Elastic Deformation of High Pressure Laminates. A Macroscopic Analysis. Theoretical Modelling and Measurements

    Författare :Bijan Adl-Zarrabi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; numerical simulation; expansion; elastic deformation; moisture transport; orthotropic; high pressure laminate;

    Sammanfattning : Deformation due to environmental changes in moisture arises in many engineering problems of practical interest. The purpose of this work is to develop a theoretical model for the determination of moisture induced deformations in thin plates made of High Pressure Laminates. LÄS MER

  5. 15. Självständighetens livsform(er) och småföretagande : tillämpning och utveckling av realistisk livsformsanalys

    Författare :Tuula Bergqvist; Jan Ch Karlsson; Tora Friberg; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Life mode analysis; independent life mode; small firms; entrepreneurship; trust; flexibility; commodity and service production; expansion; Work sciences and ergonomics; Arbetsvetenskap och ergonomi; Working Life Science; Arbetsvetenskap;

    Sammanfattning : This thesis focuses on the realist life mode analysis, especially the independent life mode, and the empirical field of entrepreneurship – running a small firm. The aim is to broaden the general understanding for entrepreneurship to include non-capitalistic rationality through application and development of realist life mode analysis. LÄS MER
