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

    Master-uppsats, SLU/Dept. Of Aquatic Resources

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

    Sammanfattning : 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. LÄS MER

  3. 2. The Operational Strategy Optimization of Distributed Energy System Based on MATLAB : A case study in Northeast China

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Yujun Han; [2023]
    Nyckelord :Distributed Energy System; CCHP; operational strategy; Distribuerat energisystem; CCHP; operativ strategi;

    Sammanfattning : China is the largest energy consumer worldwide, with a fast-growing rate. But the energy and environmental problems brought by its unbalanced energy structure and low energy efficiency restrict the sustainable development of China. The Distributed Energy System (DES) is one of the internationally recognized solutions to the problems. LÄS MER

  4. 3. Data Centres as Prosumers: A Techno-Economic Analysis

    Master-uppsats, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Jeremy Ericsson Sintong; [2023]
    Nyckelord :Data Centres; Prosumers; Techno-Economic Analysis; Waste Heat Recovery; District Heating; Heat Supply; Air-Cooled Data Centre;

    Sammanfattning : Rapid growth of digitalization has urged Data Centres (DC) to be more energy efficient by recovering waste heat from server racks that would otherwise be wasted. This techno-economic study is focused on upgrading low temperature waste heat from typical Air-Cooled DC for District Heating Network (DHN) market in Stockholm region. LÄS MER

  5. 4. Energy Poverty : Computing the silent problem of developed countries

    Kandidat-uppsats, Uppsala universitet/Institutionen för samhällsbyggnad och industriell teknik

    Författare :Alfred Larsson; Märta Strømme; Herman Falkenmark; Freja Klucis; [2023]
    Nyckelord :Energy Poverty;

    Sammanfattning : Energy poverty is a new term in the Swedish context, though it is becoming increasingly more relevant because of inflation and higher prices for electricity. Because research on the matter is scarce in developed countries such as Sweden and similar contexts in the EU, it creates uncertainty whether there is a ‘correct’ way of conducting energy poverty research.

  7. 5. Jämförande studie av uppmätt energiförbrukning mellan aktivitetsmätarna ActiGraph och ActiCal hos unga vuxna

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Pediatrisk inflammations- och metabolismforskning samt barnhälsa

    Författare :Oliver Cronsten; Mattias Edman; [2023]
    Nyckelord :actical; actigraph; activity monitor; energy expenditure; actical; actigraph; aktivitetsmätare; energiförbrukning;

    Sammanfattning : Fysisk aktivitet är en viktig del i alla människors liv och på senare år har flera tekniker utvecklats för att mäta just denna parameter. Detta har bidragit till en stor utveckling bland flertalet olika portabla tekniker, ofta i form av aktivitetsmätare, för att underlätta mätningar för alla inblandade. LÄS MER
