  1. 1. A Case-Based Reasoning System for the Diagnosis of Individual Sensitivity to Stress in Psychophysiology

    Författare :Shahina Begum; Peter Funk; Helena Lindgren; Mälardalens högskola; []
    Nyckelord :Artificial Intelligence; Case-based reasoning; Sensor; Signals; Stress; Diagnosis; Computer-based system; TECHNOLOGY; TEKNIKVETENSKAP; Datavetenskap; Computer Science;

    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. 2. Characterisation of nystagmus waveforms in eye-tracker signals

    Författare :William Rosengren; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Eye tracking; Signal processing; Nystagmus;

    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. 3. Methods for Objective and Subjective Video Quality Assessment and for Speech Enhancement

    Författare :Muhammad Shahid; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Video Quality Assessment; No-Reference Methods; Reduced-Reference Methods; Subjective Experiments; Speech Enhancement; Adaptive Gain Equalizer;

    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. 4. Neutron Multiplicity Counting with the Analysis of Continuous Detector Signals

    Författare :Lajos Nagy; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kolmogorov equation; fissile material assay; nuclear safeguards; fission chamber; neutron multiplicity counting; master equation;

    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. 5. Combination of space-geodetic techniques in the era of VGOS and multi-GNSS

    Författare :Periklis Diamantidis; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Local Ties; EOP; Reference Systems; GNSS; VLBI; Combination on the Observation Level; multi-GNSS; Space Geodesy; VGOS;

    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
