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

    Detta är en avhandling från Gävle : Gävle University Press

    Författare :Ding Ma; Högskolan i Gävle.; [2018]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

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

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Martin Mickelsson; David Kronlid; Anna Danielsson; Rob O’Donoghue; [2020]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Sustainable development; environmental and sustainability education; scaling; scaling-up; implementation gap; learning; Curriculum Studies; Didaktik;

    Sammanfattning : 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. LÄS MER

  3. 3. The Principle of Scaling of Geographic Space and its Application in Urban Studies

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Xintao Liu; KTH.; Högskolan i Gävle.; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; geographic space; scaling; GIScience; VGI; OSM; heavy-tailed distribution; the head tail division rule; space syntax; nature street; urban sprawl; floating car data; hierarchical spatial structure;

    Sammanfattning : Geographic space is the large-scale and continuous space that encircles the earth and in which human activities occur. The study of geographic space has drawn attention in many different fields and has been applied in a variety of studies, including those on cognition, urban planning and navigation systems. LÄS MER

  4. 4. Multitemporal Spaceborne Polarimetric SAR Data for Urban Land Cover Mapping

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Xin Niu; KTH.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; RADARSAT-2; spaceborne; polarimetric SAR; urban land cover; classification; TECHNOLOGY Information technology; TEKNIKVETENSKAP Informationsteknik;

    Sammanfattning : Urban represents one of the most dynamic areas in the global change context. To support rational policies for sustainable urban development, remote sensing technologies such as Synthetic Aperture Radar (SAR) enjoy increasing popularity for collecting up-to-date and reliable information such as urban land cover/land-use.

  5. 5. Statistically Guided Visualization and Exploratory Analysis of Omics Data

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Charlotte Soneson; [2011]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bioinformatics; Exploratory analysis; Multidimensional Scaling; Omics data; Principal component analysis; Visualization;

    Sammanfattning : This thesis deals with methods for extracting robust and relevant information from high-dimensional data sets, and statistically guided visualization methods for representing the data in an informative and easily accessible way. High-dimensional data sets are becoming increasingly prevalent in many different scientific disciplines. LÄS MER
