16. Acquisition strategies for fat/water separated MRI
Abstract : This thesis focuses on new ways to more efficiently acquire the signal for fat/water separated MRI, also known as Dixon methods. In paper I, the concept of dual bandwidths was introduced to improve SNR efficiency by removing dead times in a spin echo PROPELLER sequence. READ MORE

17. On Reduced Rank Linear Regression and Direction Estimation in Unknown Colored Noise Fields
Abstract : Two estimation problems are treated in this thesis. Estimators are suggested and the asymptotical properties of the estimates are investigated analytically. Numerical simulations are used to assess small-sample performance. In addition, performance bounds are calculated. READ MORE

18. Positioning and Tracking in Asynchronous Wireless Sensor Networks
Abstract : This thesis deals with the problem of locating mobile nodes in anasynchronous wireless communication network, i.e., a wireless network of mobileterminals where some or all nodes do not have access to a global time reference. READ MORE

19. Statistical Learning, Dynamics and Control : Fast Rates and Fundamental Limits for Square Loss
Abstract : Learning algorithms play an ever increasing role in modern engineering solutions. However, despite many recent successes, their performance in the context of dynamical and control systems is not exactly well-understood. READ MORE

20. Wireless Sensor Network Positioning Techniques
Abstract : Position information is one of the key requirements for wireless sensor networks(WSNs). Since GPS receivers have drawbacks when used in low-power sensor nodes,mainly due to latency in position recovery and limited access to GPS satellites in indoor-type scenarios, extracting the position information by means of the network itself, so-called positioning or localization, has been considered an eective solution for the posi-tioning problem.
