  1. 1. Geometrical and dimensional Measurement Planning : - a systematic and holistic approach

    Författare :Richard Lindqvist; Lars Mattsson; Martin Helgoson; KTH; []
    Nyckelord :Geometrical; dimensional; measurement planning; controllability; GMCP; quality assurance matrix and methodology; QAM; critical key characteristic;

    Sammanfattning : För att försäkra sig om den slutliga kvaliteten på maskinbearbetade komponenter måste tillverkande företag mäta och verifiera de geometriska och dimensionella egenskaperna på komponenter innan dem skickas vidare nedströms till den mer värdeskapande monteringen. Det är idag vanligt att den geometriska och dimensionella mätningen och verifieringen uppstår varje gång då en maskin ställs om, när man startar om eller startar upp en ny produktionslina eller då en produktionsprocess ändras.

  3. 2. Non-metallic inclusions in pipeline steels and their effect on the corrosion resistance

    Författare :Elena Sidorova; Andrey Karasev; Pär Jönsson; Lauri Holappa; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pipeline steels; Ca-treatment; non-metallic inclusions; electrolytic extraction; corrosion; chemical extraction; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning :  This thesis focus on investigations of the influence of non-metallic inclusions on corrosion in steel samples taken at different stages of the steel production when producing pipeline steels. The electrolytic extraction technique was used to extract inclusions from these steel samples and thereafter studying them using scanning electron microscopy in combination with energy dispersive microscopy.

  4. 3. Nitride fuel production by the internal sol gel process

    Författare :Marcus Hedberg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nitride fuels; ZrN; internal sol gel;

    Sammanfattning : AbstractDuring operation of a fourth generation reactor system it is necessarily not desirable to utilize an oxide fuel matrix as in light water reactor systems. One type of chemical compounds that has been suggested is nitride based nuclear fuel. LÄS MER

  5. 4. Ink Jetting of Photochromic Ink : Towards the Design of a Smart Textile Sensor

    Författare :Sina Seipel; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inkjet printing; UV curing; photochromic; UV-sensing; smart textile; resource-efficient; scCO2 dyeing; jetting; dye kinetics; color performance; durability; stabilization; Textil och mode generell ; Textiles and Fashion General ;

    Sammanfattning : Smart textiles have been a hot topic in research for several decades; however, comparatively few products can be found on the market. Resource-efficient processes can boost the breakthrough of smart and functional textiles, which often necessitate high-cost materials and only require small batches. LÄS MER

  7. 5. Ethanol from Sugarcane Lignocellulosic Residues - Opportunities for Process Improvement and Production Cost Reduction

    Författare :Stefano Macrelli; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Bioethanol from sugarcane is a sustainable alternative to fossil fuels, and the increasing demand for fuel ethanol has prompted studies on the use of the lignocellulosic residues of sugarcane, namely bagasse and leaves, as new feedstock. This thesis describes various process designs and the economic feasibility of producing second generation (2G) ethanol from bagasse and leaves via the enzymatic route in an integrated sugarcane biorefinery, where first-generation (1G) ethanol is produced from sugarcane sugar.
