  1. 26. Scalable Parallelization of Expensive Continuous Queries over Massive Data Streams

    Författare :Erik Zeitler; Tore Risch; Elke Rundensteiner; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap med inriktning mot databasteknik; Computer Science with specialization in Database Technology;

    Sammanfattning : Numerous applications in for example science, engineering, and financial analysis increasingly require online analysis over streaming data. These data streams are often of such a high rate that saving them to disk is not desirable or feasible. Therefore, search and analysis must be performed directly over the data in motion. LÄS MER

  3. 27. Mining data streams to increase ‎industrial product availability

    Författare :Ahmad Alzghoul; Patrik Eklund; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Sammanfattning : Improving product quality is always of industrial interest. Product availability, a function of product maintainability and reliability, is an example of a measurement that can be used to evaluate product quality. LÄS MER

  4. 28. Contaminant transport in non-uniform streams and streambeds

    Författare :Jonas K. Forsman; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Sub-surface transient storage; reactive tracers; analytical solutions; Geovetenskap; Earth sciences; Geovetenskap; Sedimentology; sedimentologi;

    Sammanfattning : The interplay between hydraulic and chemical processes in streams and adjacent storage zones, e.g. streambed sediments, is of crucial importance for the large-scale transport of released contaminants. This thesis presents a methodology for tracer experiments and the development of mechanistic transport models. LÄS MER

  5. 29. Process Design for Ultrafiltration of Complex Process Streams

    Författare :Anna-Karin Nordin; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bleach plant effluent; Ultrafiltration; process design; optimization;

    Sammanfattning : Considerable effort has been dedicated over the years to model and simulate the ultrafiltration process. Most approaches are theoretical and therefore not applicable to industrial process streams. When treating such solutions, a combination of experiments and simulations is needed. LÄS MER

  7. 30. Nutrient recovery from waste streams through struvite formation

    Författare :Maryam Latifian; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; struvite; nutrient; phosphorus; nitrogen; wastewater treatment; anaerobic digestion; urine;

    Sammanfattning : Eutrophication or the nutrient enrichment of water bodies, typically by nitrogen and phosphorus has adversely affected the aquatic life and the quality of water. Governments have been forced to take actions in order to reduce the release of these nutrients into the environment. LÄS MER
