  3. 2. Towards sustainable heavy-duty transportation : Combustion and emissions using renewable fuels in a compression ignition engine

    Författare :Maja Novakovic; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; RME; HVO; E85; methanol; ethanol; decarbonization; defossilization; heavy-duty; compression-ignition engine; ow temperature combustion; PPC; emissions; PM; particles; aerosol; OA; SOA; DOC;

    Sammanfattning : Transportation should become sustainable and available to everyone. Currently, transportation accounts for approx. one sixth of greenhouse gas (GHG) emissions globally, and heavy-duty trucks are responsible for almost 30% of that. LÄS MER

  4. 3. From Condition Monitoring to Maintenance Management in Electric Power System Generation with focus on Wind Turbines

    Författare :Peyman Mazidi; Miguel Ángel Sanz Bobi; Lina Bertling Tjernberg; Javier García González; KTH; []
    Nyckelord :Anomaly Detection; Condition Monitoring; Maintenance Management; Performance Evaluation; Data Analytics; Mathematical Modeling; Optimization; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : With increase in the number of sensors installed on sub-assemblies of industrial components, the amount of data collected is rapidly increasing. These data hold information in the areas of operation of the system and evolution of health condition of the components. LÄS MER

  5. 4. Air Pollution Dependency on Climate Variability and Source Region : Past, Current and Future Air Pollution Scenarios over Europe

    Författare :Camilla Andersson; Hans-Christen Hansson; Christer Johansson; Joakim Langner; David Simpson; Peter Builtjes; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Acidification; Air Pollution; Climate Change; Europe; Numerical Model; Emission; Eutrophication; Key region; Nitrogen Dioxide; Particulate Matter; PM; Source region; Surface Ozone; Tropospheric Ozone; Earth sciences; Geovetenskap; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : The main objectives of this thesis were to investigate the dependency of European air pollution on climate variability and emission source region. Calculations with a chemistry transport model (CTM) were conducted to investigate the influence of climate variability. LÄS MER

  7. 5. Measurement and Modelling using Surface Complexation of Cation (II to VI) Sorption onto Mineral Oxides

    Författare :Anna-Maria Jakobsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; surface complexation; goethite; UO2.sup.2 ; alumina; sorption; Co.sup.2 ; NpO2.sup. ; Pm.sup.3 ; Th.sup.4 ; TiO2;

    Sammanfattning : The aim of this work was to experimentally and theoretically study some surface complexation models and how well these can be applied to a simple system. This is done while keeping in mind the interest in including some type of chemical model in performance assessment calculations for much more complex systems. LÄS MER
