  1. 1. A study on the Submerged Entry Nozzels (SEN) respecting clogging and decarburization

    Författare :Arashk Memarpour; Pär Jönsson; Sune Jansson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Refractory; SEN; Clogging; REM; Coating; glaze; alkaline; Refractory; ZrSi2; Graphite; Alumina; Oxidation; Al2O3-C; ZrO2-C; MgO-C; decarburization; reaction mechanism; Materials science; Teknisk materialvetenskap;

    Sammanfattning : The submerged entry nozzle (SEN) has been used to transport the molten steel from tundish to the mould. The main purpose of the SEN usage is both to prevent oxygen and nitrogen pick-up by molten steel and to achieve the desired flow condition in the mould. LÄS MER

    Sammanfattning : The purpose of this dissertation is to describe and analyze how the Royal House of Bernadotte maintained and strengthened its legitimacy in the united kingdoms of Sweden and Norway during the first half of the 19th century. Sweden’s repeated military setbacks during the first decade of that century had undermined the last vestiges of the autocratic monarchy’s legitimacy, and as a consequence King Gustav IV Adolf was deposed in a military coup in March 1809.

  4. 3. A Simulation-Based Safety Analysis of CACC-Enabled Highway Platooning

    Författare :Maytheewat Aramrattana; Tony Larsson; Cristofer Englund; Jonas Jansson; Vicente Milanés; Högskolan i Halmstad; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; simulation; driving simulator; traffic simulator; network simulator; C-ITS; cooperative intelligent transport systems; platooning;

    Sammanfattning : Cooperative Intelligent Transport Systems (C-ITS) enable actors in the transport systems to interact and collaborate by exchanging information via wireless communication networks. There are several challenges to overcome before they can be implemented and deployed on public roads. LÄS MER

  5. 4. Cutting Edge Titanium-based CVD Hard Coatings

    Författare :Linus von Fieandt; Mats Boman; Ulf Jansson; Erik Lindahl; Tommy Larsson; Henrik Pedersen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; CVD; Hard coatings; Ti C; N ; TiN;

    Sammanfattning : Modern tools for metal cutting applications, such as turning or milling, are typically improved with a thin protective coating. Despite being only a few microns thick, the coating can increase the lifetime of the tool by more than 100 times compared to an uncoated tool. Two different types of techniques are normally used to deposit the coatings, i. LÄS MER

  7. 5. Genus Brachyspira in birds : phenotypes, phylogeny and pathogenicity

    Författare :Desirée Jansson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Spirochaetes of genus Brachyspira colonize the large intestine of some mammals and birds, and cause intestinal disease and production losses in pigs and chickens. The precise significance of Brachyspira spp. colonization in birds, the bacterial species involved, and the epidemiology are incompletely understood. LÄS MER
