  1. 16. Inductive measurement of narrow gaps for high precision welding of square butt joints

    Författare :Edvard Svenman; Anna-Karin Christiansson; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Eddy current; Seam tracking; Measurement; Laser beam welding; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : A recent method in aero engine production is to fabricate components from smaller pieces, rather than machining them from large castings. This has made laser beam welding popular, offering high precision with low heat input and distortion, but also high productivity. LÄS MER

  3. 17. Value-based management - positioning of claimed merits and analysis of application

    Författare :Peter W Jönsson; Företagsekonomiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; adoption; management process aspects; objective; performance measurement; strategic planning; remuneration; MVA; EVA; TBR; CFROI; Accounting; TSR; measurement aspects; management accounting constructs; Value-based management; management accounting; Redovisning;

    Sammanfattning : Value-based management has attracted considerable interest among organizations and academics in recent years. Responding to calls for case-based research, this thesis describes, analyses and conceptualizes value-based management as a management accounting construct. While previous research has focused on the measures (eg. LÄS MER

  4. 18. Recycling of TiO2 Pigments from Waste Paint: Process Development, Surface Analysis, and Characterization

    Författare :Mikael Karlsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Recycling; Recovery; Paint; Titanium dioxide; Waste.; Municipal solid waste handling; Pyrolysis; Pigment;

    Sammanfattning : Pigments are commonly used in paint, plastic and paper products and titanium dioxide (TiO2), the most important white pigment, accounts for approximately 70 % of the total volume of all pigments used today. Minerals containing TiO2 are relatively abundant in the earth’s crust. LÄS MER

  5. 19. Process Control and Simulation of Ferromagnetic Strip in the Power Transformers and Electrical Machines Applications : Electric power systems

    Författare :Kourosh Mousavi Takami; Jafar Mahmoudi; Örjan Danielsson; Mihai Nicolescu; Mälardalens högskola; []
