  1. 1. Virtual Full Replication for Scalable Distributed Real-Time Databases

    Författare :Gunnar Mathiason; Sten F. Andler; Sang H. Son; Hans Hansson; Alejandro Buchmann; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; Scalability; Flexibility; Adaptiveness; Database Replication; Resource Management; Distributed Database; Real-time Database; Computer science; Datalogi; Information technology; Informationsteknik; Teknik; Technology;

    Sammanfattning : A fully replicated distributed real-time database provides high availability and predictable access times, independent of user location, since all the data is available at each node. However, full replication requires that all updates are replicated to every node, resulting in exponential growth of bandwidth and processing demands with the number of nodes and objects added.

  2. 2. Scalable and Reliable Data Stream Processing

    Författare :Paris Carbone; Seif Haridi; Peter Pietzuch; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; distributed systems; stream processing; data management; databases; distributed computing; data processing; fault tolerance; database optimisation; programming systems; data science; data analytics; computer science; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : Data-stream management systems have for long been considered as a promising architecture for fast data management. The stream processing paradigm poses an attractive means of declaring persistent application logic coupled with state over evolving data. LÄS MER

  3. 3. Managing Applications and Data in Distributed Computing Infrastructures

    Författare :Salman Zubair Toor; Sverker Holmgren; Dirk Düllmann; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Distributed Computing Infrastructures; Grids; Clouds; Application Management; Distributed Storage; Resource Allocation; Beräkningsvetenskap; Scientific Computing;

    Sammanfattning : During the last decades the demand for large-scale computational and storage resources in science has increased dramatically. New computational infrastructures enable scientists to enter a new mode of science, e-science, which complements traditional theory and experiments. LÄS MER

  4. 4. Scalable Queries over Log Database Collections

    Författare :Minpeng Zhu; Tore Risch; Peter Gray; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap med inriktning mot databasteknik; Computer Science with specialization in Database Technology;

    Sammanfattning : In industrial settings, machines such as trucks, hydraulic pumps, etc. are widely distributed at different geographic locations where sensors on machines produce large volumes of data. The data produced is stored locally in autonomous databases called log databases. LÄS MER

  5. 5. Capturing semi-automated decision making : the methodology of CASADEMA

    Författare :Maria Nilsson; Tom Ziemke; Joeri van Laere; Tarja Susi; Amy Loutfi; Ann Bisantz; Örebro universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; Decision making; distributed cognition; human-computer interaction; semi-automated processes; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Information technology; Informationsteknologi; Datalogi; Computer and Systems Science; Decision Making; Distributed Cognition; Human-Computer Interaction; Information Fusion; Semi-Automated processes; Teknik; Technology;

    Sammanfattning : This thesis presents a new methodology named CASADEMA (CApturing Semi-Automated DEcision MAking) which captures the interaction between humans and the technology they use to support their decision-making within the domain of Information Fusion. We are particularly interested in characterising the interaction between human decision makers and artefacts in semi-automated fusion processes. LÄS MER
