  2. 1. Track circuits’ robustness : Modeling, measurement and simulation

    Author : Emilio Rodriguez; Ajit Kumar Verma; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Track circuit; Relay; False positive signals; Signalling in railway; Modelling; Simulation; Testing; Robustness; Interoperability; Reliability; Railway Infrastructure; Drift och underhållsteknik; Operation and Maintenance Engineering;

    Abstract : In countries with rough weather conditions, frequent delays cause railway companies to waste time and money. Many of these delays are related to the train detection systems, as the old DC track circuits are still used in some countries, including Sweden, our case study. READ MORE

  4. 2. Linear Model Predictive Control : Stability and Robustness

    Author : Johan Löfberg; Lennart Ljung; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Most real systems are subjected to constraints, both on the available control effort and the controlled variables. Classical linear feedback is in some cases not enough for such systems. This has motivated the development of a more complicated, nonlinear controller, called model predictive control, MPC.

  5. 3. An ALARP Stop-Test Decision for the Worst-Case Timing Characteristics of Safety-Critical Systems

    Author : Mahnaz Malekzadeh; Sasikumar Punnekat; Iain Bate; Hans Hansson; Karl Meinke; Mälardalens högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer Science; datavetenskap;

    Abstract : Safety-critical systems are those in which failure can lead to loss of people’s lives, or catastrophic damage to the environment. Timeliness is an important requirement in safety-critical systems, which relates to the notion of response time, i.e., the time a system takes to respond to stimuli from the environment. READ MORE

  6. 4. Product Configuration from a Mathematical Optimization Perspective

    Author : Peter Lindroth; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; optimization; multiple objectives; platform-based products; heavy-duty trucks; configuration management; categorical variables; global optimization; robustness; categorical variables;

    Abstract : The optimal truck configuration for a certain customer is very specific and depends on for what transport mission and in which operating environment the truck is to be used. In addition, the customers normally specify other feature requirements ranging from visual appearance to advanced driver support systems. READ MORE

  7. 5. Robustness During Learning, Interaction and Adaptation for Autonomous Driving

    Author : Hannes Eriksson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Reinforcement Learning; Epistemic Uncertainty; Uncertainty Quantification; Machine Learning; Autonomous Driving;

    Abstract : In a sequential decision-making process, it is imperative to consider the potential risks of taking incorrect decisions throughout the whole process as all wrongdoings may not be possible to be remedied. This is particularly important when there are potentially catastrophic consequences. READ MORE
