  1. 16. A Composable and Extensible Environment for Equation-based Modeling and Simulation of Variable Structured Systems in Modelica

    Författare :John Tinnerholm; Adrian Pop; Martin Sjölund; Peter Fritzson; Christopher Rackauckas; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Modeling and Simulation are usually used to solve real-world problems safely and efficiently by constructing digital models of Cyber-Physical Systems. The models can be simulated and analyzed with respect to requirements, and decisions about their design can be based on this analysis. LÄS MER

  3. 17. Traffic Monitoring using Road Side Sensors: Modeling and Estimation

    Författare :Roland Hostettler; Thomas Schön; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

    Sammanfattning : In many modern societies, different sensors have started to penetrate life in many new ways.Examples include personal devices for monitoring health and well-being, supervision and power distribution in the smart grid, or smart farming that takesweather and soil conditions into account to efficiently cultivate fields.

  4. 18. Tidig aritmetisk kunskapsbildning : Ett radikalkonstruktivistiskt perspektiv

    Författare :Göta Eriksson; Siv Fischbein; Olof Magne; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Radical Constructivism; model building; ontogenesis of arithmetic; counting scheme; cognitive system of self-regulation and self-organising; conceptual progression; longitudinal approach; special education.; Education; Pedagogik;

    Sammanfattning : From a Radical Constructivist (RC) perspective this thesis deals with children’s construction of early arithmetic learning as an evolving process through the cognitive system of self-regulation and self-organising. Thus the child’s learning must guide teaching. RC views early arithmetic as verbal and preceding the system of written arithmetic. LÄS MER

  5. 19. Ultrasound Communication through Thin Plates: Understanding the Channel

    Författare :Asra Ashraf; Jaap van de Beek; Johan E. Carlson; Magnus Sandell; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

    Sammanfattning : Ultrasound, composed of sound waves with frequencies above the human audible range, has become widely used in various technological fields for digital communications. In the past, acoustic and ultrasonic waves were employed in military and commercial un-derwater wireless communication systems due to their superior performance compared to electromagnetic waves.

  7. 20. Runaway-electron model development and validation in tokamaks

    Författare :Mathias Hoppe; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; magnetic confinement fusion; Fokker--Planck equation; synchrotron radiation; tokamaks; runaway-electrons; plasma physics;

    Sammanfattning : Magnetic confinement fusion (MCF), in which a hot plasma at more than 100 million kelvin is confined using magnetic fields, is the most successful fusion energy concept developed to date. After decades of research, MCF devices designed to demonstrate a positive net energy output are being constructed, completing a crucial milestone on the path to making fusion a commercially viable energy source.
