  1. 16. A Framework for optimised welding of fatigue loaded structures : Applied to gas metal arc welding of fillet welds

    Författare :Erik Åstrand; Gunnar Bolmsjö; Fredrik Sikström; Heikki Remes; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GMAW; Fatigue; Welding procedures; Fillet welds; Weld quality; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : Welding is a key process for heavy steel structures, but it is also a weak link in the structure since fatigue fractures in welds are a common cause of failure. This thesis proposes several changes in order to improve the fatigue properties in acost effective way, enabling reduced weight and reduced cost of welded structures. LÄS MER

    Sammanfattning : Currently metal nanoparticles (NPs) are a subject of interest regarding many applications, in particular chemical gas sensing, as the associated environmental issues are of substantial importance. Metal NPs are attractive due to their fascinating optical properties and primarily, localized surface plasmon resonance (LSPR) which strongly depends on size and shape of NPs. LÄS MER

  4. 18. Sustainable management of dredged sediments : potential recovery of valuable compounds

    Författare :Laura Ferrans; William Hogland; Monica Odlare; Linnéuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dredged sediments; nutrients; metals; speciation; recovery; characterisation; beneficial use; life cycle assessment; extraction; plant-growing substrate; circular economy; Miljövetenskap; Environmental Science;

    Sammanfattning : Dredging of sediments occurs worldwide to increase water depth in harbours, bays, lakes and rivers, as well as to recover aquatic ecosystems. Landfilling and open-ocean discharge are traditional disposal routes for dredged material. However, the methods are restricted by environmental and legal concerns. LÄS MER

  5. 19. Automated subject classification of textual web pages, for browsing

    Författare :Koraljka Golub; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; automated classification; subject browsing; structural Web-page elements; Web page classification; document clustering; bibliographic coupling; text categorization; Subject classification;

    Sammanfattning : With the exponential growth of the World Wide Web, automated subject classification of Web pages has become a major research issue in information and computer sciences. Organizing Web pages into a hierarchical structure for subject browsing is gaining more recognition as an important tool in information-seeking processes. LÄS MER

  7. 20. Aspects of the Impact of Technology Integration on Agility and Supply Chain Management - the Potential of Digital Packaging Printing

    Författare :Magnus Viström; Förpackningslogistik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; agile manufacturing; Supply chain mangement; digital printing; technology;

    Sammanfattning : Shorter product life cycles (Ottosson, 2004) and more diversified offers of products (Olsmats, 2002) are market trends in the present day. Companies have to deal with customers with rapidly changing demands, who are looking for high-quality products at low costs. LÄS MER
