  3. 2. Hydropower Area Equivalents : Reduced Models for Efficient Simulation of Large-Scale Hydropower Systems

    Författare :Evelin Blom; Lennart Söder; Arild Helseth; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Area Equivalent; Aggregation; Bilevel optimization; Large-scale hydropower; Power system simulation; Reduced model; Area-Ekvivalent; Aggregering; Två-nivå-optimering; Storskalig vattenkraft; Kraftsystemssimulering; Reducerad modell;

    Sammanfattning : With over 4000 TWh yearly electricity production worldwide, hydropower plays an important role in many power systems. Unlike many other renewable energy sources, hydropower has a certain degree of controllability and high levels of flexibility over several time scales. LÄS MER

  4. 3. Reduced Preoperative Fasting in Children

    Författare :Hanna Andersson; Peter Frykholm; Mark Thomas; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fasting; Children; Preoperative; Pulmonary Aspiration; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

    Sammanfattning : Preoperative fasting is recommended in order to reduce the risk of perioperative pulmonary aspiration. However, preoperative fasting may have negative effects on patient wellbeing and homeostasis. LÄS MER

  5. 4. Responses to reduced industrial metal emissions : An ecotoxicological study on Pied Flycatcher (Ficedula hypoleuca, Aves)

    Författare :Åsa Berglund; Erik Nyholm; John Elliott; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Toxicology; Toxikologi; Other biology; Övrig biologi; ekotoxikologi; Ecotoxicology; zooekologi; Animal Ecology; environmental science; miljövetenskap;

    Sammanfattning : Metals have been used by humans for thousands of years, and this has resulted in increased concentrations in the biosphere. The environment around point-sources, such as mines and smelters, are of particular concern, as metals may accumulate to high concentrations, and potentially reach levels toxic to the local flora and fauna.

  7. 5. Reduced Order Modeling and Substructuring : Applications in Nonlinear Structural Dynamics

    Författare :Linus Andersson; Byggnadsmekanik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reduced order modeling; Substructuring; Nonlinear dynamics; Geometrically nonlinear; Modal derivatives; Blast loading; Soft-body impact; Glass structures;

    Sammanfattning : A structural design process typically involves various load cases for which a sufficient load-bearing capacity must be demonstrated. In addition to static load cases, a verification of dynamic loads, such as blast and impact loading, may be required. LÄS MER
