  1. 1. Effects of manufacturing chain on mechanical performance Study on heat treatment of powertrain components

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Johan Fahlkrans; KTH.; KTH.; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Heat treatment; case hardening; carburising; induction hardening; gas quenching; tempering; straightening; fatigue strength; contact fatigue; fracture mechanics; Industriell ekonomi och organisation; Industrial Engineering and Management; Production Engineering; Industriell produktion; Materials Science and Engineering; Teknisk materialvetenskap;

    Sammanfattning : The increasing demands for lightweight designs with high strength call for improved manufacturing processes regarding heat treatment of steel. The manufacturing process has considerable potential to improve the mechanical performance and to obtain more reliable results with less variation. LÄS MER

  2. 2. Computational modelling of rail manufacturing

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Torbjörn Lindbäck; [2000]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Sammanfattning : The thesis deals with simulation of rail manufacturing. During the manufacturing process residual stresses arise in the rail, primarily due to cooling and straightening. These stresses can affect product performance, for example fatigue characteristics. Therefore it would be desirable to be able to predict these in an efficient way. LÄS MER

  3. 3. The Structural Basis of the Control of Actin Dynamics by the Gelsolin Superfamily Proteins

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Sakesit Chumnarnsilpa; Uppsala universitet.; [2009]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICINE Chemistry Biochemistry; MEDICIN Kemi Biokemi; biokemi; Biochemistry;

    Sammanfattning : Rearrangement of the actin cytoskeleton occurs in a variety of cellular processes and structures and involves a wide spectrum of proteins. Among these, the gelsolin superfamily proteins (GSPs) control actin organization by severing filaments, capping filament ends and bundling filaments. LÄS MER

  4. 4. Anadromous Pike in the Baltic Sea

    Detta är en avhandling från Växjö, Kalmar : Linnaeus University Press

    Författare :Olof Engstedt; Linnéuniversitetet.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Biology Terrestrial; freshwater and marine ecology Marine ecology; NATURVETENSKAP Biologi Terrestrisk; limnisk och marin ekologi Marin ekologi; Natural Science; Naturvetenskap;

    Sammanfattning : The pike (Esox lucius) is a major predator and top-down regulator in the Baltic Sea where it exists in two sympatric forms. One spawn in streams and rivers and the other one spawn in the sea. During the last decades, the habitats for both of these forms have developed in a negative way. LÄS MER

  5. 5. Aspects on Strenght Delivery and Higher Utilisation of the Strength Potential of Kraft Pulp Fibres

    Detta är en avhandling från Växjö, Kalmar : Linnaeus University Press

    Författare :Elisabet Brännvall; KTH.; [2007]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Chemical engineering Chemical process and manufacturing engineering Cellulose and paper engineering; TEKNIKVETENSKAP Kemiteknik Kemisk process- och produktionsteknik Cellulosa- och pappersteknik;

    Sammanfattning : Studies on strength delivery and related fields have so far concentrated on finding the locations in the mill where fibres are damaged and what the damages consist of. However, fibres will invariably encounter mechanical stresses along the fibreline and in this thesis a new concept is introduced; the vulnerability of fibres to mechanical treatment. LÄS MER
