  1. 21. Anomaly detection in trajectory data for surveillance applications

    Författare :Rikard Laxhammar; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Anomaly detection; trajectory analysis; statistical methods; conformal prediction; automated surveillance; Computer science; Datavetenskap; Datalogi; Computer and Systems Science; Teknik;

    Sammanfattning : Abnormal behaviour may indicate important objects and events in a wide variety of domains. One such domain is intelligence and surveillance, where there is a clear trend towards more and more advanced sensor systems producing huge amounts of trajectory data from moving objects, such as people, vehicles, vessels and aircraft.

  3. 22. Microbiological surveillance of biogas plants : focusing on the acetogenic community

    Författare :Abhijeet Singh; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Biogas process has great potential for reducing the current dependence on fossil fuels and for climate mitigation and sustainable development. In this process organic matter is decomposed under anerobic conditions by microorganisms to form biogas and a nutrient rich biofertiliser. LÄS MER

  4. 23. Task-oriented control and coordination of multi-agent systems under varying constraints

    Författare :Pian Yu; Dimos V. Dimarogonas; Carlo Fischione; Christos Cassandras; KTH; []

  7. 25. Digital Beamforming Focal Plane Arrays for Radio Astronomy and Space-Borne Passive Remote Sensing

    Författare :Oleg Iupikov; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; beamforming; spaceborne radiometers; radio telescopes; phased array feeds; reflector antenna feeds; feed-reflector interaction;

    Sammanfattning : Dense Phased Array Feeds (PAFs) for reflector antennas have numerous advantages over traditional cluster feeds of horns in a one-horn-per-beam configuration, especially in RF-imaging applications which require multiple simultaneously formed and closely overlapping beams. However, the accurate analysis and design of such PAF systems represents a challenging problem, both from an EM-modeling and beamforming optimization point of view. LÄS MER
