  1. 6. Laminated Veneer Products : Shape Stability and Effect of Enhanced Formability on Bond-Line Strength

    Författare :Lars Blomqvist; Jimmy Johansson; Hans Petersson; Dick Sandberg; Peter Niemz; Linnéuniversitetet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Forestry and Wood Technology; Skog och träteknik;

    Sammanfattning : This thesis concerns two aspects of the manufacture of laminated veneer products (LVPs). The first aspect is related to the possible improvement of the shape stability of LVPs, and the second has its starting point in the modification of the veneer for enhanced formability as well as the question of whether and how these modifications affect the bond-line strength.

  3. 7. Magnetron Sputter Epitaxy of GaN

    Författare :Muhammad Junaid; Jens Birch; Lars Hultman; Vanya Darakchieva; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : Electronic-grade GaN (0001) epilayers have been grown directly on Al2O3 (0001) substrates by reactive DC-magnetron sputter epitaxy (MSE) from a liquid Ga sputtering target in an Ar/N2 atmosphere. The as-grown GaN epitaxial film exhibit low threading dislocation density on the order of ≤ 1010 cm-2 obtained by transmission electron microscopy and modified Williamson-Hall plot. LÄS MER

  4. 8. Microstructure and property models of alloy 718 applicable for simulation of manufacturing processes

    Författare :Marie Anna Moretti; Lars-Erik Lindgren; Paul Åkerström; Jörgen Kajberg; Bijish Babu; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material characterisation; Material modelling; Alloy 718; Plasticity; Recrystallization; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : This thesis focuses on experimental characterization, understanding and modelling of nickel-based alloy 718, for a large range of loading conditions. Alloy 718 is the most widely used nickel-based superalloy, due to its high strength, high corrosion resistance and excellent mechanical properties at high temperatures. LÄS MER

  5. 9. Wireless Control of Modular Multilevel Converter Submodules

    Författare :Baris Ciftci; Hans-Peter Nee; Lennart Harnefors; Staffan Norrga; James Gross; Lars Kildehöj Rasmussen; Remus Teodorescu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 5G mobile communication; autonomous control; converter control; distributed control; electromagnetic interference; emerging technology; fault ride-through; modular multilevel converter MMC ; prototype; wireless control; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The modular multilevel converter (MMC) has extensively been used in high-voltage, high-power applications such as high-voltage dc transmission systems and flexible alternating current transmission systems. The control of MMC submodules is conventionally realized using wired communication systems. LÄS MER

  7. 10. Arbetarrörelsen, Folkets Hus och offentligheten i Bromölla 1905-1960

    Författare :Lennart Karlsson; Lars Olsson; Marion Leffler; Margareta Ståhl; Thord Strömberg; Växjö universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Folkets Hus; People s House; bourgeois public sphere; plebeian public sphere; labour movement; municipal politics; adult education; labour culture; cross class policy; History; Historia; Historia; History;

    Sammanfattning : The purpose of this dissertation is to analyze the People’s House in Bromölla as an arena for a plebeian public sphere. More specific, the analysis revolves around how the labour movement created a plebeian public sphere, the construction of the very arena and the activities there, including study circles, labour library, theatre plays, film showings, dance evenings and other amusements as parts of adult education among the working class people.
