  1. 1. Scaling sufficiency : Towards less material consumption

    Author : Ola Persson; Karin Bradley; Mikael Klintman; Kersty Hobson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Urban and Regional Studies; Urbana och regionala studier;

    Abstract : Various researchers have pointed out that avoiding further catastrophicconsequences related to the deteriorating ecological state of the planet,brought about by unsustainable production and consumption patterns,requires not only technological innovation and efficiency in productionprocesses, but also absolute reductions in energy and material use (i.e. READ MORE

  2. 2. Sharing Good Examples, Then What? : Investigations of Contingency and Continuity in the Scaling-of-ESD-Activities-as-Learning

    Author : Martin Mickelsson; David Kronlid; Anna Danielsson; Rob O’Donoghue; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Sustainable development; environmental and sustainability education; scaling; scaling-up; implementation gap; learning; Curriculum Studies; Didaktik;

    Abstract : This thesis aims to contribute to a deepened and nuanced understanding of scaling in environmental and sustainability education (ESE) research, specifically, to develop a conceptual framework for engaging with issues of scaling in policy and practice regarding education for sustainable development (ESD). Three research objectives are formulated. READ MORE

  3. 3. Sodium Salt Scaling in Black Liquor Evaporators

    Author : Mathias Gourdon; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sodium carbonate; black liquor; falling film evaporation; fouling; scaling; heat transfer; sodium sulfate;

    Abstract : Sodium salt scaling has long been recognized as a problem in the recovery cycle of kraft pulp mills, especially in black liquor evaporators. In the black liquor evaporation, as the black liquor becomes more concentrated, the sodium salts, particularly sodium carbonate and sodium sulfate, will saturate and precipitate from the solution.

  4. 4. Scaling Indoor Positioning : improving accuracy and privacy of indoor positioning

    Author : Jimmy Engström; Jan A. Persson; Åse Jevinger; Carl Magnus Olsson; Gustaf Hendeby; Malmö universitet; []

    Abstract : Our phones have many uses for positioning technologies, such as navigation, LocationBased Services (LBS), emergency positioning, fitness applications, and advertising. We trust our phones and wearables to be location-aware. READ MORE

  5. 5. Topological and Scaling Analysis of Geospatial Big Data

    Author : Ding Ma; Bin Jiang; Shaowen Wang; Högskolan i Gävle; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Third definition of fractal; scaling; topology; power law; head tail breaks; ht-index; complex network; geospatial big data; natural cities; natural streets; Hållbar stadsutveckling; Sustainable Urban Development;

    Abstract : Geographic information science and systems face challenges related to understanding the instinctive heterogeneity of geographic space, since conventional geospatial analysis is mainly founded on Euclidean geometry and Gaussian statistics. This thesis adopts a new paradigm, based on fractal geometry and Paretian statistics for geospatial analysis. READ MORE
