1. 21. 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.

   Abstract : In the midst of the green energy transition, the need for flexible grid solutions is growing. One of the most desired and suitable flexible solutions are Battery Energy Storage Systems (BESS), in both stationary and mobile applications. READ MORE

4. 23. Perceived Liveliness Impact on Sense of Safety : A Study on Women’s Perceived Safety in Human-Lacking Urban Environments through Virtual Reality

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

   Author : Ebba Rovig; [2023]
   Keywords : Perceived liveliness; women’s perceived safety; natural surveillance; street attributes; presence of others; virtual reality; urban environments; Upplevd livlighet; kvinnors uppfattade trygghet; naturlig övervakning; gatuattribut; närvaro av människor; virtuell verklighet; urbana miljöer;

   Abstract : Denna avhandling undersökte förhållandet mellan urbana attribut och upplevd livlighet och dess effekt på kvinnors upplevda säkerhet. Med utgångspunkt i teorier om naturlig övervakning [6] och vikten av att ha andra människor närvarande för att öka kvinnors säkerhet [17], utvärderades fysiska gatuattribut som förutspåddes öka miljöns livlighet.

5. 24. Managing Multiple Project Management Information Systems : A Case Study of a Swedish Manufacturing Company

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

   Author : Oskar Aazar; Simon Gamdrup; [2023]
   Keywords : Project Management; Project Management Information Systems PMIS ; Information Systems; Organization; Project Outcome; Complexity; Information Scattering; User Experience; Projektledning; Projektledningsinformationsystem PMIS ; Informationsystem; Organisation; Projektresultat; Komplexitet; Informationspridning; Användarupplevelse;

   Abstract : Project Management Information Systems (PMIS) play a critical role in supporting project outcome. However, little attention has been paid to the impact of having multiple PMIS while governing projects within organizations. This thesis explores the effects of the presence of multiple PMIS at a large manufacturing organization. READ MORE

6. 25. Industrial Machine Monitoring: Real-Time Anomalous Sound Event Detection on Low-Powered Devices

   University essay from Lunds universitet/Matematisk statistik

   Author : Alexander Magnusson; Anton Andersson; [2023]
   Keywords : Anomaly Detection; Sound Event Detection; MFCC; GMM; OCSVM; Mathematics and Statistics;

   Abstract : Traditionally fault detection in industrial machinery has been performed manually by experienced machine operators listening to the machines. However, it is desirable to automate this process to increase efficiency and improve the working environment of the operators. READ MORE
