  1. 1. Event Pattern Detection for Embedded Systems

    Författare :Jan Carlson; Björn Lisper; Christer Norström; Kim Larsen; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; event pattern detection; event algebra; event monitoring; composite events; embedded systems; Computer science; Datavetenskap; Datavetenskap;

    Sammanfattning : Events play an important role in many computer systems, from small reactive embedded applications to large distributed systems. Many applications react to events generated by a graphical user interface or by external sensors that monitor the system environment, and other systems use events for communication and synchronisation between independent subsystems.

  3. 2. Deception detection: Criminals’ beliefs and performance

    Författare :Maria Hartwig; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; : Deception detection; criminals; cues to deception; feedback hypothesis;

    Sammanfattning : This thesis examines criminals’ beliefs about cues to deception (Study I), and their ability to distinguish between truthful and deceptive statements (Study II). The rationale for studying this group is that there may be reason to believe that criminals inhabit a more beneficial environment for gaining insights into the psychology of deception. LÄS MER

  4. 3. An intuitive and resource-efficient event detection algebra

    Författare :Jan Carlson; Mälardalens högskola; []
    Nyckelord :;

    Sammanfattning : In reactive systems, execution is driven by external events to which the system should respond with appropriate actions. Such events can be simple, but systems are often supposed to react to sophisticated situations involving a number of simpel events occurring in accordance with some pattern. LÄS MER

  5. 4. Toward fully automatic earthquake detection and processing for tomography in the Hengill area

    Författare :Frederic Wagner; Ari Tryggvason; Ólafur Gudmundsson; Roland Roberts; Steven Gibbons; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earthquake detection; local-earthquake tomography; Iceland; induced seismicity; geothermal activity; Geofysik med inriktning mot seismologi; Geophysics with specialization in Seismology;

    Sammanfattning : This thesis focuses on the automation of seismic data analysis, in particular, event detection, quality assessment of detected events, and preparation of an earthquake catalogue for seismic tomography.The developed event detector uses back-propagation and stacking of a seismic trace attribute with a known velocity model to detect and locate events.

  7. 5. Automating Power Quality Analysis

    Författare :Emmanouil Styvaktakis; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pattern classification; expert systems; induction motors; power system transients; voltage dips; power system faults; power quality; Kalman filtering; power system monitoring; transformer saturation; short time Fourier transform;

    Sammanfattning : The increased requirements on supervision, control, and performance in modern power systems make power quality monitoring a common practise for utilities. Large databases are created and automatic processing of the data is required for fast and effective use of the available information. LÄS MER
