    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

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

    Författare :Fredrik Kristensen; Institutionen för elektro- och informationsteknik; []

    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

  5. 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

  7. 5. Alarm and service monitoring of large scale multi-service mobile networks

    Författare :Stefan Wallin; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Pervasive Mobile Computing; Distribuerade datorsystem;

    Sammanfattning : Two of the most important challenges in network service assurance are * an overwhelming flow of low-quality alarms * to understand the structure and quality of the delivered services This thesis proposes solutions for alarm and service monitoring that addresses monitoring of large scale multi-service mobile networks. The work on alarms are based on statistical analysis of data collected from a real-world alarm flow and an associated trouble ticket database containing the network administrators expert knowledge.
