  1. 1. Genetic variability commonly affecting neurodegeneration and neuroinflammation

    Författare :Mikael Ström; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Loss of nerve cells and axons is a common feature of common complex neurodegenerative disorders, such as Alzheimer’s and Parkinson’s diseases. However, also Multiple Sclerosis (MS), primarily an autoimmune disorder, has a prominent neurodegenerative component. LÄS MER

  2. 2. Applying lean principles and set-based approaches in product development

    Författare :Mikael Ström; RISE Research Institutes of Sweden; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Set-based design; Controlled convergence; Concept development; Lean product development; Lean transformation; Industrial introduction;

    Sammanfattning : The research described in this thesis addresses the problem of transformation to lean product development (LPD) and how to introduce and support the use of set-based design (SBD) in the concept development process. The original description of SBD does not define how to generate, evaluate and reduce a set of design solutions. LÄS MER

  3. 3. Improving engineering change processes by using lean principles

    Författare :Mikael Ström; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lean; information; engineering change; principles; PLM; product development;

    Sammanfattning : The purpose of this research was to test the usefulness of the 13 lean principles for product development by Morgan & Liker when improving an engineering change (EC) process. The EC-process was studied at four firms. The firms were active in three different industrial branches. Two of the firms are situated in Sweden and two in Finland. LÄS MER

  4. 4. On the Agglomeration of Particles in Exhaust Gases

    Författare :Ghulam Majal; Mihai Mihaescu; Mats Åbom; Mikael Karlsson; Lisa Prahl Wittberg; Henrik Ström; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multiphase flow; DES; particulate matter; exhaust after treatment; particle agglomeration; Lagrangian particle tracking; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : Particulate emissions from road transportation are known to have an adverse impact on human health as well the environment. As the effects become more palpable, stricter legislation have been proposed by regulating bodies. LÄS MER

  5. 5. Electron Tunneling and Field-Effect Devices in mm-Wave Circuits

    Författare :Mikael Egard; Fasta tillståndets fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; negative differential conductance oscillator; resonant tunneling diode; ultra-wideband; impulse radio; Wavelet generator; MOSFET; nanowire; high frequency characterization; Fysicumarkivet A:2012:Egard;

    Sammanfattning : Short high-frequency electromagnetic pulses, also referred to as wavelets, are considered for use in various short-range impulse based ultra-wideband applications, such as communication, imaging, radar, spectroscopy, and localization. This thesis investigates field-effect and tunneling based semiconductor devices and their operation in millimeter-wave (mm-wave) impulse transceivers. LÄS MER
