  2. 2. Data-Centric Network of Things A Method for Exploiting the Massive Amount of Heterogeneous Data of Internet of Things in Support of Services

    Detta är en avhandling från Stockholm : Department of Computer and Systems Sciences, Stockholm University

    Författare :Bin Xiao; Stockholms universitet.; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Internet of Things; Big Data; Artificial Intelligence; Data Supply; Distributed System; data- och systemvetenskap; Computer and Systems Sciences;

    Sammanfattning : Internet of things (IoT) generates massive amount of heterogeneous data, which should be efficiently utilized to support services in different domains. Specifically, data need to be supplied to services by understanding the needs of services and by understanding the environment changes, so that necessary data can be provided efficiently but without overfeeding.

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; prototyping; model-based UI development; web engineering; interaction design; Människa-datorinteraktion; Human-computer Interaction;

    Sammanfattning : There is a growing amount of digital information available from Open-Data initiatives, Internet-of-Things technologies, and web APIs in general. At the same time, an increasing amount of technology in our lives is creating a desire to take advantage of the generated data for personal or professional interests. LÄS MER

  5. 5. 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
