  2. 11. NOx Abatement Technique for Marine Applications - Improved SCR Systems

    Author : Mathias Magnusson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sulfur dioxide; Human-Machine system; NOx reduction; Water; urea-SCR catalyst; Marine applications; Human element.;

    Abstract : Growing awareness of the environmental implications of emissions of nitrogen oxides (NOX), such as eutrophication and acidification on land and at sea, has contributed to the development of more stringent international NOx legislations within the framework of IMO, with the most stringent legislation, Tier III, representing a NOx reduction of approximately 80% compared with today’s engines. Several NOx abatement technologies are available on the market, the most effective of which may be Selective Catalytic Reduction (SCR). READ MORE

  4. 12. High Temperature Corrosion of Superheaters in Biomass - and Waste-Fired Boilers: Combat on two fronts

    Abstract : Modern railway infrastructures, especially bridges, are exposed to significant vibrations with potential safety implications. In this context, previous studies have shown the inconsistency and inadequacy of some conventional design methods necessitaing them to be improved. The assessment of safety inherently deals with uncertainties. READ MORE

  6. 14. Does Form follow Function? Connecting Function Modelling and Geometry Modelling for Design Space Exploration

    Abstract : Vehicles are becoming increasingly complex and are prone to faults and failures, which threaten the dependability of vehicles in terms of availability, reliability, safety, and security. When vehicles are detected with certain types of faults and get into alarm situations, human drivers play a vital role in deciding what strategies and actions to take.
