  1. 1. Slab track optimisation considering dynamic train–track interaction

    Författare :Emil Aggestam; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modelling; Genetic algorithm; Slab track; Transition zones; Dynamic vehicle–track interaction; Optimisation; Measurement; Ballastless track;

    Sammanfattning : Slab track is a type of railway track that is frequently used e.g. in high-speed applications as an alternative to ballasted track. Slab track is also well suited on bridges and in tunnels since no ballast is required and the cross-section of tunnels can be reduced. LÄS MER

  3. 2. Similarity-Based Test Effort Reduction

    Författare :Daniel Flemström; Daniel Sundmark; Afzal Wasif; Eduards Enoiu; Miroslaw Staron; Emelie Engström; Vahid Garousi; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Software Testing; Computer Science; datavetenskap;

    Sammanfattning : Embedded computer systems are all around us. We find them in everything, from dishwashers to cars and airplanes. They must always work correctly and moreover, often within certain time constraints. The software of such a system can be very large and complex, e. LÄS MER

  4. 3. The automation effect: Investigating factors that influence the driver response process in a safety-relevant event during assisted driving and after unsupervised automation

    Författare :Linda Pipkorn; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; driving performance; automated driving; driver behaviour; driver response; test track; take over; response process; automation;

    Sammanfattning : Introduction: Safe vehicle automation can be achieved through a detailed understanding of drivers’ ability to respond to a safety-relevant event after a period of automated driving. For instance, there is a need to understand in which scenarios automation effects are present (e.g. delayed response, degraded driving performance, crashing). LÄS MER

  5. 4. Integrated High-Fidelity Planetary Mission Simulators: A Toolkit for Fidelity Evaluation

    Författare :Susmita Mohanty; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LMLSTP; partial simulator; INTEGRITY; simulation fidelity; MDRS; full mission simulator; ISEMSI; planetary mission simulator; integrated planetary mission simulator; simulator; space mission simulator; EXEMSI; fidelity evaluation checklist; fidelity evaluation framework; partial simulation; chamber isolation test; SFINCSS; simonaut; trade-off studies; integrated simulation; full mission simulation; NEEMO; simulator fidelity; HUBES; isolation test; FMARS; framework toolkit; simulation; integrated simulator; baseline mission visualization tool;

    Sammanfattning : Integrated High-Fidelity Planetary Mission Simulators: A Toolkit for Fidelity EvaluationSusmita Mohanty Department of Architecture Chalmers University of TechnologyABSTRACTFuture missions to deep space or other planets will rely heavily on Planetary Mission Simulators. Simulators will be used to replicate the experience and conditions of such missions as faithfully as possible within terrestrial constraints. LÄS MER

  7. 5. Modelling and laboratory investigations on freight wagon link suspensions with respect to vehicle-track dynamic interaction

    Författare :Per-Anders Jönsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; railway; freight wagon; running gear; link suspension; laboratory test; ; Other engineering mechanics; Övrig teknisk mekanik;

    Sammanfattning : The link suspension is the most prevailing suspension system for freight wagons in central and western Europe. The system design is simple and has existed for more than 100 years. However, still its characteristics are not fully understood. LÄS MER
