  1. 6. Ett dynamiskt perspektiv på individuella skillnader av heuristisk kompetens, intelligens, mentala modeller, mål och konfidens i kontroll av mikrovärlden Moro

    Författare :Fredrik Elg; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; complexed dynamic systems; Ravens matrices; Computer science; Datavetenskap;

    Sammanfattning : Theories predicting performance of human control of complex dynamic systems must assess how decision makers capture and utilise knowledge for achieving and maintaining control. Traditional problem solving theories and corresponding measures such as Ravens matrices have been applied to predict performance in complex dynamic systems. LÄS MER

  3. 7. A WCET Analysis Method for Pipelined Microprocessors with Cache Memories

    Författare :Thomas Lundqvist; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; real-time systems; data cache; infeasible paths; pipeline; instruction cache; dynamically scheduled processor; worst-case execution time; timing analysis; path analysis; timing anomaly;

    Sammanfattning : When constructing real-time systems, safe and tight estimations of the worst case execution time (WCET) of programs are needed. To obtain tight estimations, a common approach is to do path and timing analyses. LÄS MER

  4. 8. Anomaly detection in the surveillance domain

    Författare :Christoffer Brax; Lars Niklasson; Göran Falkman; Dimiter Driankov; Henric Johnson; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Anomaly Detection; Information Fusion; Visual Surveillance; Maritime Domain Awareness; Datalogi; Computer and Systems Science; Teknik;

    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.

  5. 9. Security-Aware Design of Cyber-Physical Systems for Control Applications

    Författare :Rouhollah Mahfouzi; Petru Ion Eles; Zebo Peng; Samarjit Chakraborty; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : With cyber-physical systems opening to the outside world, security can no longer be considered a secondary issue. In this work, we focus on security threats to control applications in cyber-physical systems. LÄS MER

  7. 10. Signal Processing for Spectroscopic Applications

    Författare :Erik Gudmundson; Peter Stoica; Peter Händel; Stoica Stoica; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spectral estimation; spectroscopic techniques; MRI; NMR; NQR; signal detection; parameter estimation; missing data; non-uniform sampling; damped sinusoids; detection of explosives; T1-mapping; relaxometry; brain imaging; skin imaging; blood velocity estimation; medical ultrasound; Signal processing; Signalbehandling; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Sammanfattning : Spectroscopic techniques allow for studies of materials and organisms on the atomic and molecular level. Examples of such techniques are nuclear magnetic resonance (NMR) spectroscopy—one of the principal techniques to obtain physical, chemical, electronic and structural information about molecules—and magnetic resonance imaging (MRI)—an important medical imaging technique for, e.
