  1. 1. Machine Learning model applied to Reactor Dynamics

    Master-uppsats, KTH/Fysik

    Författare :Dionysios Dimitrios Nikitopoulos; [2023]
    Nyckelord :Master Thesis; Machine Learning; stability; Energy distribution profiles; Prediction; frequency; decay ratio; Data processing; POLCA-T; Pytorch; testing data; RMSE. ii;

    Sammanfattning : This project’s idea revolved around utilizing the most recent techniques in MachineLearning, Neural Networks, and Data processing to construct a model to be used asa tool to determine stability during core design work. This goal will be achieved bycollecting distribution profiles describing the core state from different steady statesin five burn-up cycles in a reactor to serve as the dataset for training the model.

  3. 2. Advancements of 3D Bioprinting : A market development study

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

    Författare :Alexander Brandt; [2023]
    Nyckelord :3D bioprinting; Market; market developmet; Technology readiness levels;

    Sammanfattning : In most cases new technology emergence does not guarantee overnight success nor is it developed overnight, rather it is a result of industry expertise spanning over several fields of research. 3D bioprinting is an industry that promises revolutionary implications for healthcare and scholars are discussing application areas such as tissue for oncology research, tissue for patient specific drug development and lastly complex organs for implantation.

  4. 3. Svenska hästägares erfarenheter av lastning med häst

    Kandidat-uppsats, SLU/Dept. of Animal Environment and Health

    Författare :Elsa Widström; [2023]
    Nyckelord :häst; lastning; träning; transportfordon; enkät;

    Sammanfattning : Studies have shown that struggle during loading of horses is a well-known problem. Horses are flight animals who usually avoid dark and narrow places where the view of their surroundings are limited. Horses are also naturally neophobic, which can cause problems when loading and training horses to load. LÄS MER

  5. 4. Post-Fire Vegetation Recovery Monitoring using MODIS Time Series: A Case Study in California

    Kandidat-uppsats, KTH/Geoinformatik

    Författare :Julia Edje; [2023]
    Nyckelord :vegetation recovery; MODIS; HRT; EVI; fire; burn severity; land cover; climate zone; California;

    Sammanfattning : Human-caused forest fires have increased in magnitude and frequency, affecting global vegetation and requiring a re-evaluation of fire regimes. Changing fire regimes have led to reduced burned areas in fire- dependent ecosystems and increased areas in fire-independent ecosystems, resulting in changes in land cover and posing a threat to native plant communities.

  7. 5. Preliminary Design of a 30 kN Methane-Oxygen-powered Electric-Pump-fed Liquid Rocket Propulsion System

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Vikramjeet Das; [2023]
    Nyckelord :rocket engine; liquid rocket; methalox; electropump; LRPS; LPRE; liquid methane; electric pump feed system;

    Sammanfattning : The design of a liquid rocket propulsion system, unlike that of a standalone system, is intertwined with the overall development of a number of associated systems and is influenced by a multitude of conditions and considerations: from the requirements needed to accomplish the mission to the rationalizations involved behind the development of each rocket system and/or component. In my thesis, the preliminary design of a “new generation” 30 kN rocket engine driven by an electric pump feed system and running on liquid methane and liquid oxygen is performed. LÄS MER
