1. Övervakning och kontroll på arbetsplatsen. En kvalitativ studie om kontroll och övervakning på hybrida arbetsplatser i ekonomibranschen
Kandidat-uppsats, Göteborgs universitet/Företagsekonomiska institutionenSammanfattning : Hybrid workplaces are becoming increasingly common, integrating office-based work with remote work. Consequently, the objective of this report is to investigate hybrid workplaces within the finance industry, aiming to contribute insights into the experience of surveillance and control by employees and managers.

2. Control of carbon dioxide capture from biomass CHP plants : Designing a suitable control system to realize the flexible operation of the CO2 capture system
Master-uppsats, Mälardalens universitet/Akademin för ekonomi, samhälle och teknikSammanfattning : This degree project studies the integration of carbon capture system into biomass fired combined heat and power (bio-CHP) plants. The key disturbances from bio-CHP plants include flue gas flow rate, carbon dioxide (CO2) concentration and available heat for the reboiler because the use of versatile biomass and the dynamic operation of CHP plants results in large fluctuations in the properties of flue gas and the heat input for CO2 capture.

3. 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)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.

4. Control Aid Implementation -Modelling and simulation of triple extruder-
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : In the production of their High Voltage Direct Current Cables (HVDC) and High Voltage Alternating Current Cables (HVAC), NKT uses triple extruders to create layers of insulation and semi-conduction. A model to predict the effect of extruder inputs on the cable’s insulation and semi-conducting layers has been created and trained to predict the extruder in discrete time. LÄS MER
5. Evaluation of key performance indices for frequency quality : A method for evaluating frequency stability in the Nordic power system
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The Nordic power system is in a changing phase, with more power electronic interfaced connections, and HVDC connections to other synchronous areas, which impacts the frequency quality. This is a challenge for the transmission system operator of Sweden, Svenska Kraftnät, who, with the other Nordic transmission system operators, is responsible for the physical balancing of the Nordic power system.
