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

   Författare :Edison Pignaton de Freitas; Tony Larsson; Carlos Eduardo Pereira; Franz Josef Rammig; Högskolan i Halmstad; []
   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

5. 4. Reactive Navigation Methods for Autonomous Robots: Safety, Coordination, and Field Deployment

   Författare :Björn Lindqvist; George Nikolakopoulos; Christoforos Kanellakis; Alberto Bemporad; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Field Robotics; NMPC; Obstacle Avoidance; Collision Avoidance; Multi-agent Systems; Robot Navigation; Robotics and Artificial Intelligence; Robotik och artificiell intelligens;

   Sammanfattning : In the new era of intelligent systems, small-scale electronics, and advanced sensors, the application use-cases and operational capabilities of autonomous robots are exponentially increasing. Through their ability to execute complex tasks while relying only on onboard sensors and computation, autonomous field robots are showing promising results in inspection of infrastructure, search-and-rescue or surveillance, maintenance tasks, or in general operations in areas that prove to be dangerous or hazardous for human operators to enter, while also often increasing the efficiency of such tasks.

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

   Författare :Zoran Sjanic; Fredrik Gustafsson; Thomas Schön; Fulvio Gini; Linköpings universitet; []
   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
