  1. 11. Uncertainties in rainfall-runoff modelling of green urban drainage systems : Measurements, data selection and model structure

    Författare :Ico Broekhuizen; Maria Viklander; Günther Leonhardt; Manfred Kleidorfer; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering; Centre - Centre for Stormwater Management DRIZZLE ; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ;

    Sammanfattning : Green urban drainage systems are used to avoid flooding and damages to people and property, while limiting the downstream flooding and water quality problems caused by pipe-based drainage systems. Computer models are used to analyse and predict the performance of such systems for design and operation purposes. LÄS MER

  3. 12. Chemoinformetics for green chemistry

    Författare :Tao Liu; Tomas Öberg; Ian Nicholls; Bert van Bavel; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; QSPR; PLS; Chemometrics; Chemoinformatics; Environmental chemistry; Miljökemi; Environmental Chemistry; Miljökemi;

    Sammanfattning : This thesis focuses on the development of quantitative structure-activity relationship (QSPR) models for physicochemical properties, e.g., vapor pressure and partitioning coefficients. Such models can be used to estimate environmental distribution and transformation of the pollutants or to characterize solvents properties. LÄS MER

  4. 13. Essays on Energy and Climate Policy – Green Certificates, Emissions Trading and Electricity Prices

    Författare :Anna Widerberg; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Attitudes; Carbon Dioxide; Carbon Intensity; Climate Change; Electricity; Electricity Prices; Emissions Trading; Emission Allowances; Environment; Fairness; GARCH models; Lyapunov Exponents; Market Structure; Personal Carbon Allowances; Public Opinion; Reconstructed Dynamics; Stability; Tradable Energy Quotas; Tradable Green Certificates; Volatility;

    Sammanfattning : Paper I: An Electricity Trading System with Tradable Green Certificates and CO₂-emission Allowances Combinations of various policy instruments to deal with the threat of climate change are used throughout the world. The aim of this article is to investigate an electricity market with two different policy instruments, Tradable Green Certificates (TGCs) and CO₂ emission allowances (an Emission Trading System, ETS).

  5. 14. Structure and Dynamics of Hydrated Biopolymers

    Författare :Poornima Ramamohan; Jakob Wohlert; Istvan Furo; Fritjof Nilsson; KTH; []
    Nyckelord :Hydrated Polysaccharides; Molecular Dynamics Simulations; Structure-Function Properties; Convergence of Equilibrium Timescales; Chemical Heterogeneity; Hydrerade polysackarider; molekylära dynamiksimuleringar; struktur- funktionsegenskaper; konvergens av jämviktstidskalor; kemisk heterogenitet; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Hydrated polysaccharide systems primarily using xylans along with mutans and alternans were studied using long atomistic simulations over a few microseconds to analyse structure-function relationships and nanoscale interactions with moisture. The influence of various structural and chemical factors such as alignment, nature of glycosidic linkage, effect of moisture / chemical substitutions was explored with a focus on structure-dynamics correlations to aid in the effective functionalisation of biomaterials for the development of a green, circular bioeconomy.

  7. 15. Hydrological modelling of green urban drainage systems : Advancing the understanding and management of uncertainties in data, model structure and objective functions

    Författare :Ico Broekhuizen; Maria Viklander; Günther Leonhardt; Jörg Rieckermann; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering; Centre - Centre for Stormwater Management DRIZZLE ; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ;

    Sammanfattning : The use of green urban drainage systems such as green roofs, swales and pervious areas has in recent years become a popular option to reduce flood risk and water quality problems in a more sustainable way than with traditional pipe-based drainage systems. Computer models are valuable tools for the management of such systems. LÄS MER
