  1. 1. How to Reduce Geometrical Variation in Assembled Products

    Författare :Johan S Carlson; Johan Carlson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; assembled products; body-in-white BIW ; dimensional variation; geometrical variation; fixtures; fixture diagnosis; locating schemes; multivariate analysis; rigid body motion; robust design; root cause; quality; root cause;

    Sammanfattning : Vehicle problems, such as wind noise, water leakage and door closing effort are examples of quality and functionality defects that are controlled by the dimensional accuracy of the structural frame of an auto body. The aim of this thesis is towards methods for reducing geometrical variation in assembled products in the automotiv other industries. LÄS MER

  3. 3. Visualising the Effect of Geometrical Variation in Assembled Products. Predicting Visual Quality Appearance

    Författare :Casper Wickman; Chalmers University of Technology; []
    Nyckelord :tolerancing; visual quality appearance; distance perception; empirical studies; method development; visual sensitivity; and geometric variation; virtual reality;

    Sammanfattning : Today, when an industrial design concept is evaluated in an aesthetic manner, little or no consideration is given to geometrical variation, i.e. the concept is evaluated with nominal geometry. LÄS MER

  4. 4. Protein adaptability involved in self-assembled icosahedral capsids

    Författare :Josefina Nilsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; BK virus; lumazine synthase; virus-like particle; electron cryomicroscopy; quasiequivalence; assembly;

    Sammanfattning : Interactions between viral coat proteins determine the size and shape of the virus capsid. Therefore, the plain closed shell of a spherical virus provides an excellent resource for studying and testing protein-protein interactions so as to reveal the properties that lead to symmetrical capsids or other shapes.

  5. 5. Molecular studies of initial atmospheric corrosion of copper : Exploration of ultra-sensitive techniques for the inhibiting effect of self assembled monolayers, and the effect of gamma radiation

    Författare :Saman Hosseinpour; Christofer Leygraf; Franz Geiger; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Corrosion; copper; self assembled monolayer; sum frequency spectroscopy; qcm; gamma radiation;

    Sammanfattning : Atmospheric corrosion indoors is of great practical importance for the degradation of metals, for example in electronics, military equipment, and cultural heritage items. It involves a wide range of chemical, electrochemical, and physical processes occurring in gas, liquid, and solid phases, and at the interfaces between them. LÄS MER
