    Abstract : Solid oxide fuel cells (SOFCs) are attracting increasing interest as devices with potentialuses in decentralized and clean electricity and heat production. Several challengeswith respect to materials have to be overcome to achieve efficiencies and life-spansthat are sufficient for long-term applications. READ MORE

  2. 2. Robotic Friction Stir Welding for Flexible Production

    University dissertation from Lund : Lund University

    Author : Jeroen De Backer; Högskolan Väst.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell arbetsvetenskap; Industrial engineering; Mechatronics; Mekatronik; Friction Stir Welding; Automation; Robotics; Aluminium; Lightweight design;

    Abstract : Friction Stir Welding eller ”friktionsomrörningssvetsning” är en svetsprocess som kräver ett roterande verktyg som genom friktionsvärme får materialet att mjukna. Verktyget blandar runt det plastiska materialet mekaniskt och skapar en fog av hög kvalité. READ MORE

  3. 3. Performance-based costing as decision support for development of discrete part production : Linking performance, production costs and sustainability

    University dissertation from Division of Production and Materials Engineering, Lund University

    Author : Christina Windmark; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2018-07-20]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Production cost; PERFORMANCE; decision support; manufacturing; production development; performance-based costing; sustainability; organizational learning; Production cost; Performance; Decision support; Manufacturing; Production development; performance-based costing; Sustainability; Organizational learning;

    Abstract : Svensk tillverkningsindustri bidrar till ca 16 % (Statistics Sweden 2016) av bruttonationalprodukten och medverkar till att ca 900 000 av landets invånare har en anställning (Produktion2030 2016), vilket gör sektorn till en viktig del av Sveriges välfärdssystem. Forskningen syftar främst till att ge industrin verktyg för att analysera och utvärdera produktion för resurseffektivare och lönsammare tillverkning som även minskar miljöbelastningen. READ MORE
