  3. 2. Physical process effects on catchment-scale pollutant transport-attenuation, coastal loading and abatement efficiency

    Författare :Georg Lindgren; Georgia Destouni; Roko Andricevic; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Efficient pollutant load abatement; groundwater-surface water interactions; biogeochemical cycles; nitrogen; Lagrangian stochastic travel time approach; GIS; Hydrology; Hydrologi;

    Sammanfattning : Pollutants follow various subsurface and surface water pathways from sources within a catchment to its outlet and may cause detrimental effects on downstream water quality and ecosystems. Along their different transport pathways through a catchment, pollutants may be attenuated subject to different physical and biogeochemical processes. LÄS MER

  4. 3. Water and Carbon Balance Modeling: Methods of Uncertainty Analysis

    Författare :John Juston; Per-Erik Jansson; Georg Lindgren; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modeling; uncertainty analysis; water balance; carbon balance; GLUE; Environmental engineering; Miljöteknik;

    Sammanfattning : How do additional data of the same and/or different type contribute to reducing model parameter and predictive uncertainties? This was the question addressed with two models – the HBV hydrological water balance model and the ICBM soil carbon balance model – that were used to investigate the usefulness of the Generalized Likelihood Uncertainty Estimation (GLUE) method for calibrations and uncertainty analyses.  The GLUE method is based on threshold screening of Monte Carlo simulations using so-called informal likelihood measures and subjective acceptance criterion.

  5. 4. Glory and failure : The difference engines of Johann Müller, Charles Babbage and Georg and Edvard Scheutz

    Författare :Michael Lindgren; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : This book presents a social and technical analysis of the first attempts to mechanize the production of numerical tablets. It deals with an age when the word "computer" denoted a human being and not a machine. LÄS MER
