    Sammanfattning : In boundary-layer flows it is possible to reduce the friction drag by breaking the path from laminar to turbulent state. In low turbulence environments, the laminar-to-turbulent transition is dominated by local flow instabilities – Tollmien-Schlichting (TS) waves – that exponentially grows while being con- vected by the flow and, eventually, lead to transition.

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Selective Assembly; Individualization of production; Locator Adjustments; sheet metal assembly processes; Variation Simulations; Geometry Assurance;

    Sammanfattning : Dimensional deviations are a consequence of the mass production of parts. These deviations can be controlled by tightening production tolerances. However, this solution is not always desired because it usually increases production costs. LÄS MER

  4. 3. Urban livestock production in Cambodia : socio-economic benefits and public health hazards

    Sammanfattning : Keeping livestock can make an important contribution to the livelihoods of poor urban dwellers. There are concerns, however, that livestock keeping in and around urban areas may lead to environmental problems and increased incidence of disease transfer between animals and humans (zoonoses).
