  1. 11. Federated Machine Learning for Resource Allocation in Multi-domain Fog Ecosystems

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Weilin Zhang; [2023]
    Keywords : Workload Allocation; Federated Learning; Deep Q-network; Fog networks; Federated Average Aggregation;

    Abstract : The proliferation of the Internet of Things (IoT) has increasingly demanded intimacy between cloud services and end-users. This has incentivised extending cloud resources to the edge in what is deemed fog computing. The latter is manifesting as an ecosystem of connected clouds, geo-dispersed and of diverse capacities.

  3. 12. Anomaly Detection in the EtherCAT Network of a Power Station : Improving a Graph Convolutional Neural Network Framework

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Niklas Barth; [2023]
    Keywords : Unsupervised Learning; Multivariate Time Series; Graph Convolutional Neural Networks; Anomaly Detection; Industrial Control System; EtherCAT; Power Station; Electricity Grid;

    Abstract : In this thesis, an anomaly detection framework is assessed and fine-tuned to detect and explain anomalies in a power station, where EtherCAT, an Industrial Control System, is employed for monitoring. The chosen framework is based on a previously published Graph Neural Network (GNN) model, utilizing attention mechanisms to capture complex relationships between diverse measurements within the EtherCAT system.

  4. 13. Ovary spheroid formation and quality assessment using two different protocols

    University essay from KTH/Proteinvetenskap

    Author : Nikki Wallius Hiltunen; [2023]
    Keywords : ovary; fertility; spheroid; Biosilk™; three-layer gradient system; äggstock; fertilitet; sfäroid; Biosilk™; trelagers gradientsystem;

    Abstract : Redan innan födseln fastställs kvinnors fertilitet, som karakteriseras av ett begränsat antal äggblåsor, så kallade folliklar. Beståndet av folliklar minskar naturligt med åldern, samtidigt som kvinnors fertilitet beror på deras steroid- och äggproduktion. READ MORE

  5. 14. Unlocking the Potential of Battery Energy Storage Systems in the Nordic Frequency Regulation Markets : A techno-economic analysis to evaluate long-term profitability

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Theodor Ingman; Henrik von Sivers; [2023]
    Keywords : ;

    Abstract : As the Swedish power system has increased its shares of production coming from intermittent renewables, the production coming from large rotational units as nuclear, and hydropower, has decreased. Thereby, the power system has become more sensitive to sudden changes between production and consumption of electricity, increasing the risk of disruptions in the electricity grid. READ MORE

  6. 15. Evaluating the Performance of a Solar Thermal Field: A Case Study with Proposed Improvements

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Anton Segovia Lundh; [2023]
    Keywords : solar thermal; concentrated solar power CSP ; renewable energy; performance evaluation; Technology and Engineering;

    Abstract : Given the urgency of climate change, alternative energy sources, and policy strategies are needed to reach the net-zero emission goals and halt global warming. Solar thermal energy is a renewable and abundant energy source that could be a part of the solution. READ MORE
