  1. 1. Diving Deep: Seabird foraging tactics and local prey field

    University essay from SLU/Dept. Of Aquatic Resources

    Author : Elin Andersson Sjöholm; [2024]
    Keywords : Common Guillemot; Uria aalge; Optimal Foraging theory; Hydroacoustic data; resource selection;

    Abstract : Foragers in patchy environments need to decide what patches to use and how to allocate their time between them. Optimal foraging theory describes these choices through the relationship between energy expenditure and energy gain. READ MORE

  3. 2. Measuring copper abundances in the Galactic Bulge

    University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Author : Nikolei Höglinger; [2024]
    Keywords : Copper; Galaxy: abundances; Galaxy: bulge; Chemical Evolution; Physics and Astronomy;

    Abstract : Context: The chemical evolution of Cu in the Galactic bulge have been studied in a few studies using red giant branch stars, but the ages of individual red giant stars are difficult to determine. In addition, the bulge has been a challenging region of the Milky Way galaxy to obtain high-resolution spectra of stars, except when observing through certain few small fields into the bulge that are known to have low extinction.

  4. 3. Integrating Waste Heat from Hydrogen Production Into District Heating

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Fawzi Kayali; [2023]
    Keywords : Hydrogen; Electrolysis; Waste Heat Recovery; Combined Heat and Power Plant; District Heating; Simulation; Sustainable Heating Systems; Technology and Engineering;

    Abstract : The aim of this research is to explore the feasibility of the integration of waste heat from electrolyzers within a Combined Heat and Power (CHP) plant and district heating (DH) network and suggest a practical setup for integration. With the escalating emphasis on the development of green hydrogen through electrolysis powered by renewable energy, a substantial amount of waste heat is generated, typically left unused. READ MORE

  5. 4. Battery profit optimization

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Ebba Helfer; [2023]
    Keywords : Battery; 2nd life battery; Ancillary services; BESS; energy storage system; Technology and Engineering;

    Abstract : In the near future, a new market will form full of 2nd life batteries that are no longer suitable to use in electric vehicles. This since their capacity retention is too low after a few years of usage, as a consequence of two aging mechanisms; cycling aging and calendar aging. READ MORE

  6. 5. Improving the thermal climate of schools in semi-desert climate : A case study of solutions in La Guajira, Colombia

    University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

    Author : Michael Johansson; [2023]
    Keywords : Solar chimney; Thermal comfort; Classrooms; School; La Guajira; Colombia;

    Abstract : As the climate changes, hot regions like La Guajira's semi-desert will become even hotter. It is projected that the average temperature in this region will increase by 2.4 ℃ over the course of this century, with a 20 % reduction in precipitation. READ MORE
