11. Polymer-Nanoparticle Hybrid Materials for Plasmonic Hydrogen Detection
Abstract : Plasmonic metal nanoparticles and polymer materials have independently undergone rapid development during the last two decades. More recently, it has been realized that combining these two systems in a hybrid or nanocomposite material comprised of plasmonically active metal nanoparticles dispersed in a polymer matrix leads to systems that exhibit fascinating properties, and some first attempts had been made to exploit them for optical spectroscopy, solar cells or even pure art.

12. GNSS-aided INS for land vehicle positioning and navigation
Abstract : This thesis begins with a survey of current state-of-the art in-car navigation systems. The pros and cons of the four commonly used information sources — GNSS/RF-based positioning, vehicle motion sensors, vehicle models and map information — are described. Common filters to combine the information from the various sources are discussed. READ MORE

13. Autonomous Localization in Unknown Environments
Abstract : Over the last 20 years, navigation has almost become synonymous with satellite positioning, e.g. the Global Positioning System (GPS). On land, sea or in the air, on the road or in a city, knowing ones position is a question of getting a clear line of sight to enough satellites. READ MORE

14. Development of Microcomponents for Attitude and Communication Systems on Small Vehicles in Space and Extreme Environments
Abstract : In this thesis, components intended for vehicles in space and other extreme environments have been realized using microsystems technology to facilitate miniaturized, yet high-performing systems beneficial for small spacecraft and other vehicles with limited size and power.Cold gas thrusters commonly used on spacecraft basically accelerate a gaseous propellant stored under high pressure.

15. Artificial Intelligence for Non-Contact-Based Driver Health Monitoring
Abstract : In clinical situations, a patient’s physical state is often monitored by sensors attached to the patient, and medical staff are alerted if the patient’s status changes in an undesirable or life-threatening direction. However, in unsupervised situations, such as when driving a vehicle, connecting sensors to the driver is often troublesome and wired sensors may not produce sufficient quality due to factors such as movement and electrical disturbance.
