1. A Case-Based Reasoning System for the Diagnosis of Individual Sensitivity to Stress in Psychophysiology
Sammanfattning : Increased stress is a continuing problem in our present world. Especiallynegative stress could cause serious health problems if it remainsundiagnosed/misdiagnosed and untreated. In the stress medicine, clinicians’measure blood pressure, ECG, finger temperature and breathing rate during anumber of exercises to diagnose stress-related disorders. LÄS MER
2. Characterisation of nystagmus waveforms in eye-tracker signals
Sammanfattning : This thesis deals with the analysis of eye–tracker signals recorded from nystagmus patients. Nystagmus is an eye movement disorder caused by an underlying condition, and patients who suffer from nystagmus express involuntary oscillating eye move- ments. LÄS MER
3. Methods for Objective and Subjective Video Quality Assessment and for Speech Enhancement
Sammanfattning : The overwhelming trend of the usage of multimedia services has raised the consumers' awareness about quality. Both service providers and consumers are interested in the delivered level of perceptual quality. The perceptual quality of an original video signal can get degraded due to compression and due to its transmission over a lossy network. LÄS MER
4. Neutron Multiplicity Counting with the Analysis of Continuous Detector Signals
Sammanfattning : Neutron multiplicity counting is a non-destructive assay method for determining the mass of fissile materials (primarily plutonium) using the measured values of the singles, doubles and triples detection rates. Traditionally, the detection rates are obtained from the counting statistics of neutron detectors. LÄS MER
5. Combination of space-geodetic techniques in the era of VGOS and multi-GNSS
Sammanfattning : The definition and maintenance of accurate and stable Earth-fixed and inertial reference frames is crucial in studying, among else, geophysical and geodynamical phenomena, precise positioning, and space navigation. The tools used to this end are space-geodetic techniques, like e.g. LÄS MER
