  1. 1. !secure(system) <=?=> !safe(system) : On Security and Safety of Industrial Software Systems

    Author : Marcus Lindner; Per Lindgren; Valeriy Vyatkin; Knut Åkesson; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; embedded systems; hard real-time; concurrency; model of computation; safety-critical; safety; security; industrial automation; RTFM; real-time for the masses; Embedded Systems; Inbyggda system;

    Abstract : The focus of our research work is on readily accessible, embedded, real-time development with concurrency support. To this end, we develop the Real-Time For the Masses (RTFM) programming framework with a model of computation based on tasks and resources and that stipulates a timing semantics. READ MORE

  2. 2. Architecting model driven system integration in production engineering

    Author : Yujiang Li; Lars Mattsson; Gunilla Franzén Sivard; Torsten J. A. Kjellberg; Mikael Hedlind; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System architecture; system integration; information model; ISO 10303; application context; implementation context; implementation model.; Production Engineering; Industriell produktion;

    Abstract : System integration is a key enabler to maximize information value in an engineering context. The valuable information is normally represented by information models which play a decisive role in the implementation of system integration. READ MORE

  4. 4. Fluid Mechanics of Vertical Axis Turbines : Simulations and Model Development

    Author : Anders Goude; Olov Ågren; Carlos Simão Ferreira; Uppsala universitet; []
    Keywords : Wind power; Marine current power; Vertical axis turbine; Wind farm; Channel flow; Simulations; Vortex model; Streamtube model; Control system; Graphics processing unit; CUDA; Fast multipole method; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : Two computationally fast fluid mechanical models for vertical axis turbines are the streamtube and the vortex model. The streamtube model is the fastest, allowing three-dimensional modeling of the turbine, but lacks a proper time-dependent description of the flow through the turbine. READ MORE

  5. 5. On Model Simplification in System Identification

    Author : Bo Wahlberg; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model simplification; System identification;

    Abstract : This report deals with the connection between system identification and model reduction. We propose an identification algorithm that is based on the least squares identification method and either of the model reduction techniques: Frequency weighted truncated balanced realization or frequency weighted optimal Hankel-norm model reduction.
