  1. 1. Scalable and Reliable Data Stream Processing

    Författare :Paris Carbone; Seif Haridi; Peter Pietzuch; KTH; []
    Nyckelord :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. 2. Scalable Scientific Stream Query Processing

    Författare :Milena Ivanova; Tore Risch; Elke A. Rundensteiner; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; data stream management systems; parallel stream processing; scientific stream query processing; user-defined stream partitioning; Computer science; Datalogi; Data- och systemvetenskap; Computer Systems Sciences;

    Sammanfattning : Scientific applications require processing of high-volume on-line streams of numerical data from instruments and simulations. In order to extract information and detect interesting patterns in these streams scientists need to perform on-line analyses including advanced and often expensive numerical computations. LÄS MER

  4. 3. Multifaceted Defense Against Distributed Denial of Service Attacks: Prevention, Detection, Mitigation

    Författare :Zhang Fu; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Data Streaming; Network Security; Overlay; Distributed Denial-of-Service; System Design; DDoS Detection; Distributed Computing;

    Sammanfattning : Distributed Denial of Service (DDoS) attacks can be so powerful that they can easily deplete the computing resources or bandwidth of the potential targets, by flooding massive packets. Internet infrastructures and network applications, including social services and communication systems for emergency management, are under the threat of the DDoS problem. LÄS MER

  5. 4. Spatio-Temporal Stream Reasoning with Adaptive State Stream Generation

    Författare :Daniel de Leng; Fredrik Heintz; Patrick Doherty; Emanuele Della Valle; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; stream reasoning; stream processing; temporal reasoning; spatial reasoning; configuration planning; intelligent robotics;

    Sammanfattning : A lot of today's data is generated incrementally over time by a large variety of producers. This data ranges from quantitative sensor observations produced by robot systems to complex unstructured human-generated texts on social media. With data being so abundant, making sense of these streams of data through reasoning is challenging. LÄS MER

  7. 5. Robust Stream Reasoning Under Uncertainty
