1. Adaptive blind deconvolution using third-order moments : exploiting asymmetry
Abstract : This thesis focuses on the use of third-order statistics in adaptive blind deconvolution of asymmetric impulsive signals. Traditional methods are typically based on fourthorder moments, which can discriminate signals with heavy-tailed probability functions (i.e. `spiky' signals) from corresponding filtered versions.

2. A Signal Processing Approach to Practical Neurophysiology : A Search for Improved Methods in Clinical Routine and Research
Abstract : Signal processing within the neurophysiological field is challenging and requires short processing time and reliable results. In this thesis, three main problems are considered.First, a modified line source model for simulation of muscle action potentials (APs) is presented. READ MORE

3. Blind equalization using third-order moments
Abstract : The use of third-order moments in blind linear equalization has been studied with emphasis on their performance in on-line methods of low complexity. Blind equalization has widespread use in areas such as digital communications, acoustics, geophysical exploration, image processing and general measurement problems. READ MORE

4. DIGITAL ANALYSIS OF CARDIAC ACOUSTIC SIGNALS IN CHILDREN
Abstract : DIGITAL ANALYSIS OF CARDIAC ACOUSTIC SIGNALS IN CHILDREN Milad El-Segaier, MD Division of Paediatric Cardiology, Department of Paediatrics, Lund University Hospital, Lund, Sweden SUMMARY Despite tremendous development in cardiac imaging, use of the stethoscope and cardiac auscultation remains the primary diagnostic tool in evaluation of cardiac pathology. With the advent of miniaturized and powerful technology for data acquisition, display and digital signal processing, the possibilities for detecting cardiac pathology by signal analysis have increased.

5. New Techniques for Estimation of Source Parameters : Applications to Airborne Gravity and Pseudo-Gravity Gradient Tensors
Abstract : Gravity gradient tensor (GGT) data contains the second derivatives of the Earth’s gravitational potential in three orthogonal directions. GGT data can be measured either using land, airborne, marine or space platforms. READ MORE
