  1. 6. Investigating the dynamics between the developing Nordic hydrogen market and the electricity system under uncertainty

    Master-uppsats, KTH/Energiteknik

    Författare :Timon Renzelmann; [2024]
    Nyckelord :energy modelling; energy storage; global sensitivity analysis; hydrogen; Method of Morris; Nordics; OSeMOSYS; uncertainty analysis; energimodellering; energilagring; global känslighetsanalys; vätgas; Morris-metoden; Nordiska länder; OSeMOSYS; osäkerhetsanalys;

    Sammanfattning : The potential of hydrogen as a clean energy carrier is hotly debated, but it promises to significantly contribute to a sustainable energy future. Hydrogen can replace fossil fuels in carbon-intensive industries, heavy transport and aviation, and support a renewable energysystem by acting as energy storage to balance intermittent supply.

  2. 7. Variation Management Strategies for Future Construction Sites: A study to address role of an equipment rental business in the energy transition

    H-uppsats,

    Författare :Ellen Blanksvärd; Frida Svensson; [2023-09-21]
    Nyckelord :battery storage; variation management; flexibility services; peak shaving; load shifting; demand side management; rental business; electrification; construction equipment; construction sites;

    Sammanfattning : Construction sites are facing challenges with high power peaks due to electrificationof heavy equipment where potential consequences are increased power tariffs locallyand risk of limited power supply. Another development is an increased intermittentpower supply due to more wind- and solar power in the electricity system, whichcauses price fluctuations. LÄS MER

    Master-uppsats, Göteborgs universitet/Institutionen för pedagogik och specialpedagogik

    Författare :Robert Mensah Ofori; [2023-06-19]
    Nyckelord :Platform-based learning; COVID-19; UTAUT theory; tertiary institution; Ghana education system;

    Sammanfattning : Aim: This study examines the role of platform-based teaching and learning in the Ghana tertiary educational system. This study focuses on the lessons from COVID-19 pandemic and explores measures to make platform-based learning sustainable. LÄS MER

  4. 9. Natural Language Inference Transfer Learning in a Multi-Task Contract Dataset : In the Case of ContractNLI: a Document Information Extraction System

    Master-uppsats, Uppsala universitet/Institutionen för lingvistik och filologi

    Författare :Yiu Kei Tang; [2023]
    Nyckelord :;

    Sammanfattning : This thesis investigates the enhancement of legal contract Natural Language Inference (NLI) classification through supervised fine-tuning on general domain NLI, in the case of ContractNLI and Span NLI BERT (Koreeda and Manning, 2021), a multi-task document information extraction dataset and framework. Annotated datasets of a specific professional domain are scarce due to the high time and labour cost required to create them. LÄS MER

  5. 10. Integration of a heat recovery system in a Spray Drying Process : Model Simulation Analysis and Economic Feasibility

    Magister-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :Marcel Hott Oller; [2023]
    Nyckelord :Spray Drying; Heat pump; Simulation model; heat recovery system;

    Sammanfattning : The spray drying process is widely established in the industry worldwide. However, due to its complexity in predicting variables, the technology is often regarded as a "Black box" process. LÄS MER
