    Sammanfattning : The Wenner-Gren Center in Stockholm, built between 1954 and 1966, consists of three buildings dedicated to interdisciplinary and scientific research, designed by Sune Lindström and Alf Bydén of Vattenbyggnadsbyrån (VBB). The project was sponsored by Axel Wenner-Gren, and received support from the Swedish state through the donation of a property at the northern end of Stockholm’s thoroughfare Sveavägen. LÄS MER

  3. 3. Design and Implementation of Embedded Video Surveillance Hardware

    Sammanfattning : The demands on video surveillance systems are rapidly increasing regarding parameters such as frame rate and resolution. Furthermore, with an ever increasing number of video streams, an automated process for extracting relevant information is required. LÄS MER

  4. 4. Obstacle Problems for Green Potentials and for Parabolic Quasiminima

    Författare :Catarina Petersson; Matematik (naturvetenskapliga fakulteten); []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Functions; differential equations; Funktioner; differentialekvationer; Matematik; degenerate parabolic operators; Mathematics; quasiminima; obstacle problems; Green potentials;

    Sammanfattning : The thesis consists of two parts. In the first part pure potential theoretic methods are employed to study the obstacle problem connected with a uniformly elliptic second-order differential operator in divergence form. Regular points of the obstacles are characterized by the classical Wiener criterion. LÄS MER

  5. 5. A Process Approach to Robust Design in Early Engineering Design Phases

    Författare :Peder Andersson; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; design principles; error transmission; design methodology; product development; design for quality; mechanical engineering; design process; conceptual design; Robust design; system design; parameter design; Taguchi; Mechanical engineering; hydraulics; vacuum technology; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik;

    Sammanfattning : The activity of robust design of mechanical products and how it can be accomplished in pre-prototype design phases, is discussed in this thesis. It is advocated that to be fully efficient and effective optimization of product robustness should commence already in the conceptual design phase. LÄS MER
