    Sammanfattning : In recent years, Intelligent Transportation Systems (ITS) have emerged as an efficient way of enhancing traffic flow, safety and management. These goals are realized by combining various technologies and analyzing the acquired data from vehicles and roadways. LÄS MER

  2. 22. Anomaly detection in trajectory data for surveillance applications

    Detta är en avhandling från Örebro : Örebro universitet

    Författare :Rikard Laxhammar; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Anomaly detection; trajectory analysis; statistical methods; conformal prediction; automated surveillance; TECHNOLOGY Information technology Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap; Computer and Systems Science; Datalogi;

    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. 23. Anomaly Detection in the Surveillance Domain

    Detta är en avhandling från Örebro universitet

    Författare :Christoffer Brax; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Anomaly Detection; Information Fusion; Visual Surveillance; Maritime Domain Awareness; Teknik; Technology;

    Sammanfattning : In the post September 11 era, the demand for security has increased in virtually all parts of the society. The need for increased security originates from the emergence of new threats which differ from the traditional ones in such a way that they cannot be easily defined and are sometimes unknown or hidden in the “noise” of daily life.

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

    Detta är en avhandling från Gothenburg : Chalmers tekniska högskola

    Författare :Oleg Iupikov; [2017]
    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

  5. 25. Security and Privacy of Sensitive Data in Cloud Computing

    Detta är en avhandling från Gothenburg : Chalmers tekniska högskola

    Författare :Ali Gholami; Erwin Laure; Seif Haridi; Schahram Dustdar; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cloud Computing; Security; Privacy; Trust; Opertaing System; Datalogi; Computer Science;

    Sammanfattning : Cloud computing offers the prospect of on-demand, elastic computing, provided as a utility service, and it is revolutionizing many domains of computing. Compared with earlier methods of processing data, cloud computing environments provide significant benefits, such as the availability of automated tools to assemble, connect, configure and reconfigure virtualized resources on demand.
