1. Feature Extraction for Low-Frequency Signal Classification
Detta är en avhandling från Stockholm : KTHSammanfattning : 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. LÄS MER
2. Symmetry Filters Applied to Fingerprints : Representation, Feature extraction and Registration
Detta är en avhandling från Göteborg : Chalmers tekniska högskolaSammanfattning : 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. LÄS MER
3. New directions in non-porous membrane extraction
Detta är en avhandling från Department of Analytical Chemistry, Lund UniversitySammanfattning : 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. LÄS MER
4. Predictive Health Monitoring for Aircraft Systems using Decision Trees and Genetic Evolution
Detta är en avhandling från Luleå University of TechnologySammanfattning : 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. LÄS MER
5. Perceptually motivated speech recognition and mispronunciation detection
Detta är en avhandling från Stockholm : KTH Royal Institute of TechnologySammanfattning : 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. LÄS MER
