  1. 11. Closed-Loop Combustion Control of a Multi Cylinder HCCI Engine using Variable Compression Ratio and Fast Thermal Management

    Författare :Göran Haraldsson; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CR; Motorer; framdrivningssystem; Motors and propulsion systems; Teknik; Technological sciences; Closed-Loop Combustion Control; CLCC; Multi cylinder; HCCI; Black box; System identification; State feedback; PID; LQG; Fast Thermal Management; FTM; VCR Variable Compression Ratio;

    Sammanfattning : The current Spark Ignited (SI) engine equipped with three-way catalyst offers low emissions, but has low efficiency at part load, which results in unnecessarily high CO2 emissions. The Compression Ignited (CI) engines have higher efficiency and hence lower CO2 emissions, but suffer from higher Nitrogen Oxide (NOx) and Particulate Matter (PM) emissions, and no three-way catalyst can be used.

    Sammanfattning : The aim of this thesis is to show how Europe is constructed at the intersection between archaeology, money and politics within EU cultural actions. Ever since the 1970s, the European Community has invested money and prestige in the idea of a common cultural heritage for Europe. LÄS MER

  4. 13. Phenolic compounds and ascorbic acid in black currant (Ribes nigrum L.) : variation due to genotype, ontogenetic stage, harvest date and location

    Författare :Michael Vagiri; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Black currant is an edible soft fruit crop that is now attracting increased scientific attention due to its high content of potentially beneficial phenolic compounds and ascorbic acid. Using HPLC and spectrophotometry, this thesis examined the content of phenolic compounds in buds, leaves and fruits of black currant plants grown in southern and northern Sweden. LÄS MER

  5. 14. Security and Risk Assessment: Black box modeling, Taxonomy and Systematic Literature Review

    Författare :Laleh Pirzadeh Irannezhad; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In order to successfully perform and manage any type of project, there is a need to identify and assess the key factors that have an effect on the project's performance and its deliverables. Security and risk are two important concepts in contemporary information system industry that need to be assessed and addressed. LÄS MER
