1. A Travelling Wave Slot Array based on a Double-Layer Lens for 77 GHz Automotive Radar
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Automotive radars have gained considerable interest in recent years for applications of road safety for vulnerable road users. The use of multipleinput and multiple-output (MIMO) technology in automotive radar has helped in realising a virtual aperture greater than the physical aperture of the antenna which has reduced the size of the overall radar module.

2. Parking Map Generation and Tracking Using Radar : Adaptive Inverse Sensor Model
Master-uppsats, Linköpings universitet/Fluida och mekatroniska systemSammanfattning : Radar map generation using binary Bayes filter or what is commonly known as Inverse Sensor Model; which translates the sensor measurements into grid cells occupancy estimation, is a classical problem in different fields. In this work, the focus will be on development of Inverse Sensor Model for parking space using 77 GHz FMCW (Frequency Modulated Continuous Wave) automotive radar, that can handle different environment geometrical complexity in a parking space.

3. Micro-Shivering Detection : Detection of human micro-shivering using a 77 GHz radar
Magister-uppsats, Högskolan i Halmstad/Akademin för informationsteknologiSammanfattning : Radars have been under steady development to track, identify, image, and classify targets. Modern radar systems, with the help of embedded systems, have additional comprehensive signal processing capabilities. They can extract useful information from very noisy data, e.g. LÄS MER
4. Transient Dynamics and Core Tunneling in Vertical Spin-Vortex Pairs
Master-uppsats, KTH/NanostrukturfysikSammanfattning : Spin-vortices in vertically spaced pairs of thin elliptical Permalloy nanoparticles are investigated. The two vortex cores with parallel out-of-plane magnetization exhibit a strong monopole-like attraction through the spacer much thinner than the core length, thus forming a bound core-core pair.

5. Evaluation of Commercial Radar Sensors for Proximity Fuze Applications
Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysikSammanfattning : Radar sensors has been known for their usage in military applications but during the last decade commercial radar sensors have been implemented for usage in for example advanced driver-assistance system. One common implementation for advanced driver-assistance system is the adaptive cruise control technology implemented in vehicles to help it adapt the velocity based on the distance to a detected vehicle in front.
