  1. 6. On the Machinability of Ductile and Strain Hardening Materials - Models and Methods for Analyzing Machinability

    Författare :Fredrik Schultheiss; Industriell Produktion; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alloy 718; Ti6Al4V; Duplex stainless steel; Machinability; Minimum chip thickness; Contact condition; Surface topography; Tool wear; Part cost; Sustainable machining; Polar diagram.;

    Sammanfattning : As quality and performance demands on today’s products increases, more and more advanced materials are being used during modern production. The problem is however that this in turn place new demands on the machining processes utilized. LÄS MER

  3. 7. QCD Phenomenology of Heavy Particle Dynamics

    Författare :Emanuel Norrbin; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; High energy interactions; heavy quarks; QCD; charm asymmetry; hadronization; string fragmentation; colour reconnection; leptoquarks; parton shower; cosmic rays; Kosmisk strålning; högenergi; Fysicumarkivet A:2000:Norrbin;

    Sammanfattning : In this thesis the phenomenology of Quantum Chromo Dynamics (QCD) is studied in a variety of circumstances from both perturbative and non-perturbative perspectives. The main emphasis is on the production and hadronization of heavy particles, specifically heavy quarks, gauge bosons, leptoquarks and supersymmetric particles. LÄS MER

  4. 8. Ageism in the Media : Online Representations of Older People

    Författare :Wenqian Xu; Annika Taghizadeh Larsson; Lars-Christer Hydén; Andreas Motel; Alexander Peine; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Ageism; Power relations; Representations of older people; Third age; Social media logic; Ålderism; Maktrelationer; Representationer av äldre; Tredje åldern; Social medialogik;

    Sammanfattning : Ageism is a social problem that has harmful effects on the wellbeing of older people and needs to be tackled. It is pervasive and evident in the media (e.g., films, television, print and social media). LÄS MER

  5. 9. Managing the fuzzy front end of product and process development : case studies of process firms

    Författare :Monika Kurkkio; Maria Elmqvist; Luleå tekniska universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Redovisning och styrning; Accounting and Control;

    Sammanfattning : This thesis addresses different aspects of how to manage product development and process development. Two research studies have been conducted, both within the process industry. LÄS MER

  7. 10. A Study of Parameters and Properties Influencing the Size, Morphology and Oxygen Content of Water Atomized Metal Powders

    Författare :Fredrik Persson; Pär Jönsson; Christopher Neil Hulme; Lauri Holappa; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : The production of metal powders by water atomization is a well-established process, which can be used to produce a wide range of particle sizes for different applications. In general, there is a lack of detailed knowledge about what process parameters that affect the powder properties for water atomized metal powders. LÄS MER
