  1. 1. Unearthing the social-ecological cascades of the fall armyworm invasion: A computer-assisted text analysis of digital news articles

    University essay from Stockholms universitet/Stockholm Resilience Centre

    Author : Kathryn Bjorklund; [2023]
    Keywords : emerging pests and pathogens; social-ecological cascades; fall armyworm; Spodoptera frugiperda; structural topic modeling;

    Abstract : Understanding the complex nature of social-ecological cascades, or chain reactions of events that lead to widespread change in a system, is crucial for navigating the challenges they present. Emerging pests and pathogens, such as the fall armyworm, provide an opportunity to study these cascades in greater detail. READ MORE

  3. 2. Evaluation of load distribution on ballasted reinforced concrete railway trough bridges

    University essay from Luleå tekniska universitet/Byggkonstruktion och brand

    Author : Alex Eriksson; [2023]
    Keywords : Concrete; numerical analysis; trough bridge; railway bridge; finite element model; discrete element method; Betong; numeriskanalys; trågbro; tågbro; finita elementmetoden; diskreta elementmetoden;

    Abstract : A significant portion of the reinforced concrete railway bridges in Sweden are reaching their designed lifespan and are scheduled to be demolished and replaced in the upcoming years. To limit the econom-icand environmental impact related to the replacement of existing railway infrastructure, a comprehen-siveevaluation of their capacity is required with the aim of extending its lifespan.

  4. 3. Co-Simulation Development for Improved Cavitation Predictions in Oil-Hydraulics Systems : An investigation into the cavitating flow behavior of repetitive water hammers.

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Thisal Mandula Sugathapala; Twan Bakker; Rahul Gudur Suresh; Aryan Delir; [2022]
    Keywords : co-simulation; water hammer; cavitation;

    Abstract : Numerical modeling of cavitation using computational software is a highly pursued topic of research due to its impact in different industrial sectors. While some industrial applications such as wastewater treatment and mineral processing are known to advantageously use this phenomena, it remains an unwanted process in others where it is known to induce vibration, reduce performance and cause structural damage.
