  1. 16. Phenomena in wire based multi-layer laser welding and hybrid deposition

    Författare :Jonas Näsström; Alexander Kaplan; Frank Brueckner; Sven Bengtsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Produktionsutveckling; Manufacturing Systems Engineering;

    Sammanfattning : Several laser materials processing technologies using metal wire addition have been researched during the last decades. Especially in the field of joining, as well as in the field of Additive Manufacturing (AM), multiple major benefits have been reached, e.g. higher welding speeds and lower heat input. LÄS MER

  3. 17. Modeling and Control for Emission Management in Hybrid Electric Commercial Vehicles

    Författare :Olov Holmer; Lars Eriksson; Christopher Onder; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Electrification of powertrains is a major trend in the vehicle industry. The reason behind this is mainly that electrification of a powertrain generally results in better fuel economy, by eliminating inefficient, low load, operation of the engine. LÄS MER

  4. 18. Towards Large-Area Electronic Systems Using Non-Conventional Substrate and Conductor Materials

    Författare :Xiaotian Li; Johan Sidén; Henrik Andersson; Leena Ukkonen; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Non-conventional materials; large-area electronics;

    Sammanfattning : Flexible circuits, also known as flexible printed circuit boards, were originally developed in the 1950s for interconnection between multiple electronic devices when flexibility and movement were required. Nowadays, flexible circuits can be used for implementing electronic systems much more complicated than just interconnections. LÄS MER

  5. 19. Controlling substrate export by the Ysc-Yop type III secretion system in Yersinia

    Författare :Ayad Amer; Matthew Francis; David L. Gally; Umeå universitet; []
    Nyckelord :Y. pseudotuberculosis; T3SS; YscX; YopD; assembly; translation control; temporal secretion.; mikrobiologi; Microbiology;

    Sammanfattning : Several pathogenic Gram-negative bacteria invest in sophisticated type III secretion systems (T3SS) to incapacitate their eukaryotic hosts. T3SSs can secrete protein cargo outside the bacterial cell and also target many of them into the eukaryotic cell interior. LÄS MER

  7. 20. Toward Energy-efficient Physical Vapor Deposition : Routes for Replacing Substrate Heating during Magnetron Sputtering by Employing Metal Ion Irradiation

    Författare :Xiao Li; Grzegorz Greczynski; Ivan Petrov; Lars Hultman; Jyh-Wei Lee; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PVD; Magnetron sputtering; Thin films; HiPIMS; TiAlN; Energy efficiency;

    Sammanfattning : In this Thesis, magnetron sputtering is perfected as an environmental-friendly deposition technique. I performed systematic studies of a novel approach - hybrid high-power impulse and dc magnetron co-sputtering (HiPIMS/DCMS) with metal-ion-synchronized substrate bias pulses. LÄS MER
