  1. 1. Air Pollution from Ships - Emission Measurements and Impact Assessments

    Författare :Hulda Winnes; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fuel; air pollution; ships; impact assessment; emission measurement; ship emissions; emission inventory; manoeuvring ships; abatement;

    Sammanfattning : Environmental impact and air pollution from ships have received increasing attention the last decades. Due to combustion characteristics of typical marine engines and a wide spread use of unrefined fuel, the global fleet emits significant amounts of SO2, NOX and particles to air. LÄS MER

  3. 2. Multi-echelon Inventory Control with Integrated Shipment Decisions

    Författare :Olof Stenius; Produktionsekonomi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inventory; Multi-echelon; Stochastic; Shipment consolidation; Delivery decisions;

    Sammanfattning : Rising fuel prices and increasing environmental awareness emphasizes the importance of the transportation aspect in logistics. This calls for new improved inventory control methods that consider the effects of shipment strategies in a more realistic manner. LÄS MER

  4. 3. Exact Methods for Multi-echelon Inventory Control : Incorporating Shipment Decisions and Detailed Demand Information

    Författare :Olof Stenius; Produktionsekonomi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inventory; Multi-echelon; Stochastic; Shipment decisions; Detailed demand information;

    Sammanfattning : Recent advances in information technologies and an increased environmental awareness have altered the prerequisites for successful logistics. For companies operating on a global market, inventory control of distribution systems is often an essential part of their logistics planning. LÄS MER

  5. 4. Isotope-based source apportionment of black carbon aerosols in the Eurasian Arctic

    Författare :Patrik Winiger; Örjan Gustafsson; Meinrat O. Andreae; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Black Carbon; Radiocarbon; Air Pollution; Arctic Amplification; Climate Change; Arctic Haze; Atmospheric Transport Modeling; Emission Inventory; Carbon Isotopes; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Aerosols change the Earth's energy balance. Black carbon (BC) aerosols are a product of incomplete combustion of fossil fuels and biomass burning and cause a net warming through aerosol radiation interactions (ari) and aerosol cloud interactions (aci). LÄS MER

  7. 5. Application of Passive DOAS using Scattered Sunlight for quantification of gas emissions from anthropogenic and volcanic sources

    Författare :Claudia Rivera; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nitrogen dioxide; DOAS; gas emission; sulphur dioxide; volcanic; formaldehyde.; scattered sunlight; anthropogenic;

    Sammanfattning : Monitoring of gas emissions from natural and anthropogenic sources is important due to the negative effects of these emissions on human health, atmospheric quality and ecosystems. Concern over air pollution has increased the need to develop measurement techniques suitable for gas flux determination. LÄS MER
