    Sammanfattning : In manufacturing industries, sensors are often installed on industrial equipment generating high volumes of data in real-time. For shortening the machine downtime and reducing maintenance costs, it is critical to analyze efficiently this kind of streams in order to detect abnormal behavior of equipment. LÄS MER

  5. 4. Efficient Data Streaming Analytic Designs for Parallel and Distributed Processing

    Författare :Hannaneh Najdataei; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stream processing; continuous analysis; scalability; elasticity;

    Sammanfattning : Today, ubiquitously sensing technologies enable inter-connection of physical objects, as part of Internet of Things (IoT), and provide massive amounts of data streams. In such scenarios, the demand for timely analysis has resulted in a shift of data processing paradigms towards continuous, parallel, and multitier computing. LÄS MER

  7. 5. Towards Unifying Stream Processing over Central and Near-the-Edge Data Centers

    Författare :Hooman Peiro Sajjad; Vladimir Vlassov; Johan Tordsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; geo-distributed stream processing; geo-distributed infrastructure; edge computing; edge-based analytics; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : In this thesis, our goal is to enable and achieve effective and efficient real-time stream processing in a geo-distributed infrastructure, by combining the power of central data centers and micro data centers. Our research focus is to address the challenges of distributing the stream processing applications and placing them closer to data sources and sinks. LÄS MER
