  1. 6. Governance and decision-making : Lessons from three French eco-villages

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

    Författare :Gwenaël Bertrand; [2023]
    Nyckelord :;

    Sammanfattning : In a context of rising environmental pressure and slow societal changes in response, the emergence of ecovillages comes as a small-scale solution to actively propose sustainable alternatives to the modern consumerist society. The human factor plays a key role in enabling such ecovillages to last. LÄS MER

  3. 7. Predictive Controllers for Load Transportation in Microgravity Environments

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Sujet Phodapol; [2023]
    Nyckelord :Model Predictive Control; Decentralized control; Multi-robot systems; Space technology; Modell-prediktiv reglering; Decentraliserad reglering; Multirobotsystem; Rymdteknologi;

    Sammanfattning : Space activities have been increasing dramatically in the past decades. As a result, the number of space debris has also increased significantly. Therefore, it is necessary to clean up and remove them to prevent a collision between space debris and spacecraft. LÄS MER

  4. 8. Exploration and Evaluation of RNN Models on Low-Resource Embedded Devices for Human Activity Recognition

    Master-uppsats, KTH/Mekatronik och inbyggda styrsystem

    Författare :Helgi Hrafn Björnsson; Jón Kaldal; [2023]
    Nyckelord :Recurrent Neural Networks; Long Short-Term Memory Networks; Embedded Systems; Human Activity Recognition; Edge AI; TensorFlow Lite Micro; Recurrent Neural Networks; Long Short-Term Memory Networks; Innbyggda systyem; Mänsklig aktivitetsigenkänning; Edge AI; TensorFlow Lite Micro;

    Sammanfattning : Human activity data is typically represented as time series data, and RNNs, often with LSTM cells, are commonly used for recognition in this field. However, RNNs and LSTM-RNNs are often too resource-intensive for real-time applications on resource constrained devices, making them unsuitable. LÄS MER

  5. 9. Styrning av vakuumpumpsystem i analyslaboratorie

    Kandidat-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :John Backman; [2023]
    Nyckelord :styrsystem;

    Sammanfattning : Denna rapport presenterar ett projekt som syftar till att skapa en applikation med tillhörande hårdvara för att styra en vakuumpump i ett analyslaboratorie som ligger i anslutning till Bolidenägda Aitikgruvan i Gällivare. Vakuumpumpen används för att generera sugkraft till dragskåp, slangar och robotutrustning där giftiga ångor sugs bort när analyseringen av gråberg inträffar. LÄS MER

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

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

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

    Sammanfattning : 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.
