21. Ultrasonic Arrays for Sensing and Beamforming of Lamb Waves
Abstract : Non-destructive testing (NDT) techniques are critical to ensure integrity and safety of engineered structures. Structural health monitoring (SHM) is considered as the next step in the field enabling continuous monitoring of structures. READ MORE

22. Optimal Detectors for Transient Signal Families and Nonlinear Sensors : Derivations and Applications
Abstract : This thesis is concerned with detection of transient signal families and detectors in nonlinear static sensor systems. The detection problems are treated within the framework of likelihood ratio based binary hypothesis testing. READ MORE

23. Parameter Estimation and Waveform Fitting for Narrowband Signals
Abstract : Frequency estimation has been studied for a large number of years. One reason for this is that the problem is easy to understand, but difficult to solve. Another reason, for sure, is the large number of applications that involve frequency estimation, e. READ MORE

24. Signal processing applied to acoustic distance estimation and sound classification
Abstract : The thesis treats some signal processing applications to retrieval of information from acoustic measurements. In the distance estimation applications (parts AI, A2, B and C) an acoustic signal propagates through a physical system and is modified according to some system parameter. READ MORE

25. Nonlinear Approaches to Periodic Signal Modeling
Abstract : Periodic signal modeling plays an important role in different fields. The unifying theme of this thesis is using nonlinear techniques to model periodic signals. The suggested techniques utilize the user pre-knowledge about the signal waveform. This gives these techniques an advantage as compared to others that do not consider such priors. READ MORE
