  1. 1. Velocity Control of a Mobile Charger in a Wireless Rechargeable Sensor Network

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

    Author : Emilia Haltorp; [2023]
    Keywords : Wireless Sensor Networks; Mobile Charger; Wireless Energy Transfer; Traveling Salesman Problem; Trådlösa Sensornätverk; Mobil laddare; Trådlös strömöverföring; Handelsresandeprobleme;

    Abstract : Wireless sensor networks (WSN) are one of the most rapidly evolving technical areas right now. They can be used in a lot of different applications, environmental monitoring and health applications being two examples. The sensors can be placed in hazardous and remote environments since there is no need for cabling or manual maintenance. READ MORE

  3. 2. 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. 3. Evaluation of Geopositioning Using Frequency Responses From Radio Propagation Measurements

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

    Author : Jessica Ye; Johan Lesko; [2023]
    Keywords : ;

    Abstract : Satellite reliant navigation systems may struggle in urban environments as tall buildings mayobstruct necessary direct lines of sight with satellites. There have been multiple studiesexamining how WIFI fingerprinting may be used for indoor positioning. READ MORE

  5. 4. Exogenous Fault Detection in Aerial Swarms of UAVs

    University essay from KTH/Matematik (Avd.)

    Author : Maja Westberg; [2023]

FOI Swedish DefenseResearch Agency provided the thesis project and research question. READ MORE

  6. 5. Development and understanding of a model V2O5/anatase TiO2(101) SCR catalyst

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Johanna Paulsson; [2023]
    Keywords : Physics and Astronomy;

    Abstract : A model V2O5/ anatase TiO2(101) SCR catalyst is studied with the purpose of developing and understanding the reaction mechanism through which this catalyst reduces NOx. Several reaction mechanisms have been proposed for this catalyst in the past, but there is still no agreement on which of these describe the reaction the best, if any. READ MORE
