    Abstract : 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. READ MORE

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

    University dissertation from Electro and information technology

    Author : Fredrik Kristensen; [2007]

    Abstract : 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. READ MORE

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

    University dissertation from Centre for Mathematical Sciences, Lund University

    Author : Catarina Petersson; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Functions; differential equations; Funktioner; differentialekvationer; Matematik; degenerate parabolic operators; Mathematics; quasiminima; obstacle problems; Green potentials;

    Abstract : 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. READ MORE

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

    University dissertation from Dept. of Machine Design, Lund Institute of Technology, P.O. Box 118, S-221 00 Lund, Sweden
