    Sammanfattning : The main body of this thesis consists of six appended papers. In the  first two, different  cooperative surveillance problems are considered. The second two consider different aspects of the trajectory planning problem, while the last two deal with observer design for mobile robotic and Euler-Lagrange systems respectively. LÄS MER

  2. 2. Cooperative Context-Aware Setup and Performance of Surveillance Missions Using Static and Mobile Wireless Sensor Networks

    Detta är en avhandling från Halmstad : Högskolan i Halmstad

    Författare :Edison Pignaton de Freitas; Högskolan i Halmstad.; [2011]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Surveillance systems; Wireless sensor network; Cooperative sensors; Mobile sensors; Biologically-inspired networking; Context awareness;

    Sammanfattning : Surveillance systems are usually employed to monitor wide areas in which their usersaim to detect and/or observe events or phenomena of their interest. The use ofwireless sensor networks in such systems is of particular interest as these networks can provide a relative low cost and robust solution to cover large areas. LÄS MER

  4. 4. Navigation and Mapping for Aerial Vehicles Based on Inertial and Imaging Sensors

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Zoran Sjanic; Linköpings universitet.; Linköpings universitet.; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Small and medium sized Unmanned Aerial Vehicles (UAV) are today used in military missions, and will in the future find many new application areas such as surveillance for exploration and security. To enable all these foreseen applications, the UAV's have to be cheap and of low weight, which restrict the sensors that can be used for navigation and surveillance. LÄS MER
