5. 4. An Intelligent Multi Sensor System for a Human Activities Space---Aspects of Quality Measurement and Sensor Arrangement

   Författare :Jiandan Chen; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3D Reconstruction; Depth Measurement; Depth Reconstruction; Dither; Human Factor; Image Quality; Iso-disparity Surfaces; Multi-Sensor System; Quality Measurement; Sensor Arrangement; Surveillance; Tracking; Uncertainty;

   Sammanfattning : In our society with its aging population, the design and implementation of a highperformance distributed multi-sensor and information system for autonomous physical services become more and more important. In line with this, this thesis proposes an Intelligent Multi-Sensor System, IMSS, that surveys a human activities space to detect and identify a target for a specific service. LÄS MER

7. 5. Sensor Networks and Their Radio Environment : On Testbeds, Interference, and Broken Packets

   Författare :Frederik Hermans; Per Gunningberg; Edith Ngai; Andreas Terzis; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sensor networks; Testbed; Mobility; Interference classification; Packet corruption; Computer Science with specialization in Computer Communication; Datavetenskap med inriktning mot datorkommunikation;

   Sammanfattning : Sensor networks consist of small sensing devices that collaboratively fulfill a sensing task, such as monitoring the soil in an agricultural field or measuring vital signs in a marathon runner. To avoid cumbersome and expensive cabling, nodes in a sensor network are powered by batteries and communicate wirelessly. LÄS MER
