11. Energy Harvesting for Health Monitoring Balises : Analytical study
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Balises are transponders installed in railways. These devices are nowadays powered by means of a radiofrequency signal emitted by each running train that passes above them. It is only during this moment that the health state of the balises is checked. READ MORE

12. Modelling and testing of a solar panel structure for KNATTE (Kinesthetic Node and Autonomous Table-Top Emulator)
University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknikAbstract : One of the challenges that satellites face is the interaction between control movement and vibration of flexible appendages such as solar arrays and antennas that can negatively affect the performance of the spacecraft. The aim of this thesis is to develop a numerical model of a solar panel structure for KNATTE, a frictionless platform developed by the Onboard Space Systems group at Luleå University of Technology, and develop a control law that reduces the flexible vibration of the solar arrays when attitude control manoeuvres are performed.

15. Sensors for intelligent and reliable components
University essay from KTH/Skolan för industriell teknik och management (ITM)Abstract : One way to tackle the climate change society is facing today is through the change to renewable energy sources, such as wind power. Today, a trend when it comes to technology is that products are evolving into becoming more cyber-physical systems (CPS) by integrating functions realized with mechanics, control and communication.
