  1. 1. Impact of Climate Change on Extreme Events: Insights from Asia and Scandinavia

    Författare :Dong An; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Climate change; extreme events; precipitation extremes; droughts; climate variability; ENSO; climate model; climate projection; the Asia-Pacific region; scandinavia;

    Sammanfattning : As climate has warmed significantly over past decades, numerous studies have confirmed a pattern of more frequent and more intense hydro-climate events across the globe, such as floods, heatwaves, and droughts. Analyzing the variability of climate events with reliable historical data records is one of the most direct approaches for understanding its patterns of change. LÄS MER

  3. 2. How can data science contribute to a greener world? : an exploration featuring machine learning and data mining for environmental facilities and energy end users

    Författare :Dong Wang; Mats Tysklind; Johan Trygg; Lili Jiang; Venkat Venkatasubramanian; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wastewater treatment; Process analytics; Big data; Machine learning; Interpretable AI; Power plants; Failure analysis; Data mining; Buildings; Energy consumption; Anomaly detection;

    Sammanfattning : Human society has taken many measures to address environmental issues. For example, deploying wastewater treatment plants (WWTPs) to alleviate water pollution and the shortage of usable water; using waste-to-energy (WtE) plants to recover energy from the waste and reduce its environmental impact.

    Sammanfattning : Xerostomia (dry mouth symptoms) is a group of incurable debilitating conditions of salivary glands caused by aging, radiation/chemical exposure, or aberrant inflammation in the salivary glands. During this PhD thesis, we aimed to evaluate whether cell-derived strategies (e.g. LÄS MER

  7. 5. Polyhydroxyalkylations for alkali-stable cationic polymers as hydroxide exchange membranes

    Författare :Dong Pan; Centrum för analys och syntes; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; quaternary ammoniums; aromatic polymers; chemical resistance; ion conductivity;

    Sammanfattning : To alleviate worldwide dependence on fossil fuels for energy production and considerably reduce CO2 emissions, green energy sources and sustainable energy solutions are in high demand. Fuel cells are environmental-friendly electrochemical devices which may use clean fuels, e.g., green hydrogen gas, to generate electricity. LÄS MER
