  1. 1. Introducing New Materials in the Automotive Industry : Managing the Complexity of Introducing New Materials in Existing Production Systems

    Författare :Fredrik Henriksson; Kerstin Johansen; Jonas Detterfelt; Johan Ölvander; Mats Winroth; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Passenger vehicles are central to Western society, and contribute to a significant part of our greenhouse gas emissions. In order to reduce emissions, the automotive industry as a whole is working to reduce mass in passenger vehicles in order to reduce energy consumption. LÄS MER

  3. 2. On Material selection and its consequences in product development

    Författare :Fredrik Henriksson; Kerstin Johansen; Alison McKay; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Technological development, and increased demands on sustainable solutions, have impacted the development of new products. New products need to be more efficient, and there are increased possibilities for a more diversified and informed decision regarding what materials are used in the product. LÄS MER

  4. 3. Nanosecond tandem optical parametric oscillators for mid-infrared generation

    Författare :Markus Henriksson; Fredrik Laurell; Gunnar Rustad; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nonlinear optics; optical parametric oscillators; quasi-phase matching; mid-infrared; linewidth narrowing; volume Bragg gratings.; Physics; Fysik;

    Sammanfattning : This thesis discusses a new scheme for generating radiation in the mid infrared spectral region, especially the 3.5-5 µm range. The scheme uses established Nd3+-lasers at 1.06 µm and down conversion in nonlinear optical crystals. LÄS MER

  5. 4. Tandem optical parametric oscillators using volume Bragg grating spectral control

    Författare :Markus Henriksson; Fredrik Laurell; Hiromasa Ito; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; optical parametric oscillators; mid-infrared; volume Bragg gratings; PPKTP; ZGP; nonlinear optics; narrowband OPO; Physics; Fysik;

    Sammanfattning : This thesis describes research on near degenerate quasi phase-matched opticalparametric oscillators (OPO) where volume Bragg gratings (VBG) are used toproduce narrow oscillation bandwidth. These OPOs are then used to pump a secondOPO to generate mid-infrared radiation. The atmospheric transmission windows in the 3. LÄS MER

  7. 5. Towards a sustainable mobility paradigm? An assessment of three policy measures

    Författare :Fredrik Johansson; Greger Henriksson; Jonas Åkerman; Pelle Envall; Sprei Frances; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Sustainable mobility paradigm; Social Practice Theory; Mobility services; flexible parking requirements; Planering och beslutsanalys; Planning and Decision Analysis;

    Sammanfattning : Transportation and mobility are important components in the organisation and structure of people´s daily activities, but the transport sector has considerable environmental impacts, e.g. greenhouse gas emissions and land use. LÄS MER
