  1. 1. Forest – stream linkages : Brown trout (Salmo trutta) responses to woody debris, terrestrial invertebrates and light

    Författare :Pär Gustafsson; Eva Bergman; Larry Greenberg; Kurt Fausch; Karlstads universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Brown trout; growth; foraging; woody debris; terrestrial invertebrates; light; riparian zone; forestry; stream; Freshwater ecology; Limnisk ekologi; Biology; Biologi;

    Sammanfattning : Forests surrounding streams affect aquatic communities in numerous ways, contributing to energy fluxes between terrestrial and lotic ecosystems. The five papers in this thesis focus on woody debris, terrestrial invertebrates and light, three factors influenced by riparian zone structure, potentially affecting streams and brown trout (Salmo trutta).

  2. 2. Fine stream wood : effects on drift and brown trout (Salmo trutta) growth and behaviour

    Författare :Åsa Enefalk; Eva Bergman; Anders Nilsson; Stanley Gregory; Karlstads universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; stream fish; wood; salmonid; trout; aquatic invertebrates; behaviour; sheltering; Biology; Biologi;

    Sammanfattning : Stream ecosystems and their riparian zones have previously been regarded as two different ecosystems, linked through numerous reciprocal subsidies. Today, ecologists agree that the stream and the riparian zone should be regarded as one system, the stream-riparian ecosystem, which is characterised largely by the subsidies between land and water.

  3. 3. Spatio-Temporal Stream Reasoning with Adaptive State Stream Generation

    Författare :Daniel de Leng; Fredrik Heintz; Patrick Doherty; Emanuele Della Valle; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; 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

  4. 4. Scalable Scientific Stream Query Processing

    Författare :Milena Ivanova; Tore Risch; Elke A. Rundensteiner; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; 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

  5. 5. Robust Stream Reasoning Under Uncertainty

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

    Sammanfattning : Vast amounts of data are continually being generated by a wide variety of data producers. This data ranges from quantitative sensor observations produced by robot systems to complex unstructured human-generated texts on social media. LÄS MER
