  2. 21. Efficiency of the trackwork scheduling process in Sweden

    Author : Daria Ivina; Trafik och väg; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railways; Maintenance management; Trackwork scheduling; Project Uncertainties; Lean; Efficiency;

    Abstract : Efficient scheduling is vital for railway maintenance, which is increasingly challenged by rising train traffic and infrastructure wear. Trackwork often necessitates the reduction of train speeds and the partial or complete closure of tracks. READ MORE

    Abstract : This thesis focuses on the chemical and isotopic features of groundwater residing in the upper 1.2 km of sparsely fractured crystalline bedrock of the Baltic Shield. READ MORE

  5. 23. Nuclear Power as a Climate Change Mitigation Option: a Modelling Approach

    Author : Mariliis Lehtveer; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CCS; sensitivity analysis; nuclear weapons proliferation; energy system model; nuclear power; climate change;

    Abstract : Although nuclear power can provide electricity with very low life cycle carbon emissions and thus reduce the cost of climate change mitigation, it also brings along many specific challenges: accident risk, need for radioactive waste management and nuclear weapons proliferation risk. Due to this controversial nature nuclear power, among other energy forms, has been relatively little studied in a climate mitigation context. READ MORE

  6. 24. A Systems perspective of Waste and Energy - Strengths and Weaknesses of the ORWARE Model

    Author : Ola Eriksson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Waste management of today in Sweden is a complex phenomenonthat demands for a scientific and systematic approach. Thecomplexity is a result of a wide variety of actors,technologies, and impact on the environment, health, and theeconomy. Waste management also has a high relevance withrespect to energy. There are direct connections as e. READ MORE

  7. 25. Environmental assessment of incinerator residue utilisation

    Author : Susanna Toller; Jon Petter Gustafsson; Dan Berggren Kleja; Erik Kärrman; Thomas H. Christensen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MSWI bottom ash; wood ash; recycling; LCA; environmental assessment; geochemical speciation modelling; dissolved organic matter; copper Cu ; Environmental engineering; Miljöteknik;

    Abstract :  In Sweden, utilisation of incinerator residues outside disposal areas is restricted by environmental concerns, as such residues commonly contain greater amounts of potentially toxic trace elements than the natural materials they replace. On the other hand, utilisation can also provide environmental benefits by decreasing the need for landfill and reducing raw material extraction. READ MORE
