1. Feature Extraction for Low-Frequency Signal Classification
Abstract : The development of the International Monitoring System (IMS) for the verification of the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) has led to a rapid revival of interest in infrasound. Furthermore, the installation of low-frequency sensors at seismic sites has increased in recent years, providing researchers with large and heterogeneous data-sets in near real-time. READ MORE

2. Symmetry Filters Applied to Fingerprints : Representation, Feature extraction and Registration
Abstract : A common framework for feature extraction in fingerprints is proposed by use of certain symmetries. The proposal includes representation, filters, and filtering techniques for common features including minutiae points, singular points and the ridge and valley patterns. READ MORE

3. New directions in non-porous membrane extraction
Abstract : Complex biological and environmental samples require a high degree of selectivity in order to determine components therein. Sensitivity measures, such as analyte pre-concentration are often required for assessing composition quantitatively. READ MORE

4. Health Monitoring for Aircraft Systems using Decision Trees and Genetic Evolution
Abstract : Reducing unscheduled maintenance is important for aircraft operators. There are significant costs if flights must be delayed or cancelled, for example, if spares are not available and have to be shipped across the world. READ MORE

5. Perceptually motivated speech recognition and mispronunciation detection
Abstract : This doctoral thesis is the result of a research effort performed in two fields of speech technology, i.e., speech recognition and mispronunciation detection. Although the two areas are clearly distinguishable, the proposed approaches share a common hypothesis based on psychoacoustic processing of speech signals. READ MORE
