    Abstract : Decarbonisation of the building stock is essential for energy transitions towards climate-neutral cities in Sweden, Europe and globally. Meeting 1. READ MORE

  5. 3. 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

  6. 4. Living Structure for Understanding Human Activity Patterns Using Multi-Source Geospatial Big Data

    Author : Zheng Ren; Bin Jiang; Stefan Seipel; Itzhak Benenson; Högskolan i Gävle; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; living structure; topological representation; human activities; natural cities; urban centres; complex network; head tail breaks; big data; Hållbar stadsutveckling; Sustainable Urban Development;

    Abstract : Geographic space is not neutral or lifeless, but an intricate living structure composed of numerous small features and a few large ones across all scales. The living structure is crucial for comprehending how geographic space shapes human activities. READ MORE

  7. 5. Controlled growth of hexagonal GaN pyramids and InGaN QDs

    Author : Anders Lundskog; Erik Janzén; Urban Forsberg; Per-Olof Holtz; Lars-Erik Wernersson; Linköpings universitet; []
    Keywords : ;

    Abstract : Gallium-nitride (GaN) and its related alloys are direct band gap semiconductors, with a wide variety of applications. The white light emitting diode (LED) is of particular importance as it is expected to replace energy inefficient light bulb and hazardous incandescent lamps used today. READ MORE
