  1. 1. Substation Digitalization for Medium Voltage Urban Distribution Networks : A Techno-Economic Analysis

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Diego Molina Mendizábal; [2023]
    Nyckelord :Continuity of supply; incentive scheme; SAIDI; techno-economic analysis; Kontinuitet i försörjningen; incitamentsprogram; SAIDI; teknisk-ekonomisk analys;

    Sammanfattning : High and medium-voltage digital substations play an essential role in the energy transition since they are part of the equipment required to deploy smart grids. With the gradual increase of smart grids, energy systems are becoming more flexible with the growing penetration of renewable energies and distributed energy generation. LÄS MER

  3. 2. Modelling the Impact of Climate and Socio-Economic Changes on Nutrient Dynamics in the Catchment of Lake Vomb

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Yanhe Zhou; [2023]
    Nyckelord :Climate change; hydrological modelling; nutrient; RCP; socioeconomic development; SSP; SWAT; water quality modelling;

    Sammanfattning : Climate change and socio-economic development are greatly affecting the quality of freshwater, especially the excessive accumulation of nutrients (N and P), which eventually leads to the occurrence of eutrophication. Lake Vomb is one of the main sources of drinking water in southern Sweden and the nutrient load from the catchment makes it a eutrophic lake with recurring algal blooms. LÄS MER

  4. 3. Optimerad sandwichvägg i prefabricerad betong

    Uppsats för yrkesexamina på grundnivå, Linnéuniversitetet/Institutionen för byggteknik (BY)

    Författare :Majed Alsmail; Baqer Rubaij; [2023]
    Nyckelord :sandwich elements; thin concrete slabs; outer concrete layer; anchoring; anchoring systems; granular rupture in outer layer; anchor pull-out; adhesion; outer layer failure; loads; reinforcement; recesses; sandwichelement; tunna betongskivor; yttre betongskiva; förankring; förankringssystem; konbrott i yttre skivan; bygel utdrag; vidhäftning; brott i ytterskiva; belastningar; armering; ursparningar;

    Sammanfattning : As part of the work in this project, a literature review is conducted to determine the optimal thickness of the outer concrete layer in prefabricated concrete sandwich elements. These elements are used as exterior walls in buildings and consist of a load-bearing inner concrete layer, an intermediate insulation layer, and an outer concrete layer that forms the building's facade.

  5. 4. Synergistic fire- and mechanical effect of biochar and ammonium polyphosphate in epoxy composite

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Anton Olausson; Ludvig Jönsson; [2023]
    Nyckelord :Ammonium polyphosphate; Biochar; Composite; Epoxy; Synergistic effect;

    Sammanfattning : Polymer composites are used in a varying extent and are challenging the use of traditional materials due to the push towards sustainable development. They have replaced steels and aluminum alloys in applications. LÄS MER

  7. 5. Real time control of an active pendulum arm suspension system for a downscaled XT28 forwarder model

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Niclas Määttä; Adam Westermark; [2023]
    Nyckelord :mechatronics; offset-free MPC; MPC; LQR; XT28; forwarder; pendulum arm; forestry; mekatronik; offset-free MPC; MPC; LQR; XT28; skotare; pendelarm; skogsbruk;

    Sammanfattning : A forwarder named XT28 has been developed in joint collaboration between eXtractor AB, Skogforsk AB, KTH, Linköpings Unversity, Sveaskog, and Bosch Rexroth. The forwarder is equipped with six hydraulic active suspension pendulum arms. LÄS MER
