  1. 6. Research and reflections on European air pollution policy support models

    Författare :Stefan Åström; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Economic perspectives; Decomposition analysis; Policy support modelling; Short-lived Climate Pollutants; Climate metrics; Air pollution; International shipping; Economic methodology; Integrated assessment modelling; Cost-benefit analysis;

    Sammanfattning : European emissions to air of SO2, NOx, PM2.5, NH3 and NMVOC still today cause harm to human health and the environment. These pollutants are associated with the premature death of ~400 000 people annually in the EU (25 000 perished in traffic accidents 2017). Improvements are expected but problems will persist.

  4. 8. Enhancing Short-Term Traffic Prediction for Large-Scale Transport Networks by Spatio-Temporal Clustering

    Författare :Matej Cebecauer; Erik Jenelius; Wilco Burghout; Francisco Camara Pereira; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; short-term prediction; clustering; spatio-temporal clustering; day-types; speed-flow relationship; large-scale; Transportsystem; Transport Systems;

    Sammanfattning : Congestion in large cities is responsible for extra travel time, noise, air pollution, CO2 emissions, and more. Transport is one of the main recognized contributors to global warming and climate change, which is getting increasing attention from authorities and societies around the world. LÄS MER

  5. 9. Safety Culture in Sea and Aviation Transport

    Författare :Åsa Ek; Ergonomi och aerosolteknologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; organizational climate; air traffic control; safety culture; passenger shipping; airport ground handling; Social sciences; Samhällsvetenskaper; Development psychology; Utvecklingspsykologi; Applied and experimental psychology; Tillämpad och experimentell psykologi; Technological sciences; Teknik; Säkerhetsteknik; Safety technology;

    Sammanfattning : The research presented in this thesis investigates sea and aviation transport safety culture, with a focus on perceptions and attitudes. A safety culture reflects the attitudes, beliefs, perceptions, and values that individuals share in relation to safety. LÄS MER

  7. 10. On Particle Transport and Turbulence Modification in Air-Particle Flows

    Författare :Camilla Ljus; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; turbulent dispersion; hot film probe; turbulence measurements; turbulence modification; particle transport; two-fluid model;

    Sammanfattning : The transport of particles by airflow was studied for two different flow cases, the transport of pulp fibres in a mat-forming process and the transport of pulp fibres and spherical particles in a horizontal pipe. The transport of pulp fibres in the mat-forming process is first considered. LÄS MER
