  2. 1. Neural and Cognitive Effects of Hearing Loss on Speech Processing

    Author : Eline Borch Petersen; Thomas Lunner; Stefan Stenfelt; Jonas Obleser; Edmund Lalor; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hearing loss; speech processing; electroencephalogram EEG; working memory; cognitive load; hearing aid; Hörselnedsättning; bearbetning av tal; elektroencefalogram EEG; arbetsminne; kognitiv belastning; hörapparat;

    Abstract : Understanding speech in the presence of noise can be difficult, especially when suffering from a hearing loss. This thesis examined behavioural and electrophysiological measures of speech processing with the aim of establishing how they were influenced by hearing loss (internal degradation) and listening condition (external degradation).

  4. 2. Hypnosis monitoring during general anaesthesia : with focus on awareness

    Author : Andreas Ekman; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Hypnosis monitoring; electroencephalogram; BIS; AAI; neuromuscular block;

    Abstract : An objective measure of the hypnotic component of general anaesthesia has been sought for decades. The electroencephalogram (EEG) was early recognized as a possible useful intraoperative monitor when the effects of anaesthetic drugs on human EEG recordings were noted. READ MORE

  5. 3. On methods for pattern recognition with application to epileptic electroencephalograms

    Author : Patrik Wahlberg; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; clustering; EEG signal processing; epilepsy; statistical robustness; feature extraction; signal alignment; denoising; Wiener filtering; time-frequency analysis.; Signal processing; Signalbehandling;

    Abstract : The thesis treats methods for pattern recognition in multichannel electroencephalogram (EEG) signals, for application to diagnostics of epilepsy. Parts I-IV treat methods for feature extraction and clustering of EEG spikes, occurring between epileptic seizures, and part V presents a method for filtering seizure onset EEG signals. READ MORE

  6. 4. The bladder and the brain : Studies on the pathogenesis and the treatment of nocturnal enuresis

    Author : Tryggve Nevéus; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Obstetrics and gynaecology; nocturnal enuresis; children; desmopressin; osmoregulation; sleep; arousal; detrusor instability; incontinence; oxybutynin; Obstetrik och kvinnosjukdomar; Obstetrics and women s diseases; Obstetrik och kvinnosjukdomar; pediatrik; Pediatrics;

    Abstract : Opinions differ as to whether nocturnal enuresis is caused by high arousal thresholds, nocturnal polyuria or nocturnal bladder instability. In spite of the currently available therapeutic options - the antidiuretic drug desmopressin and alarm treatment - approximately 25% of children suffering from enuresis cannot be successfully treated.

  7. 5. Spectral Analysis for Signal Detection and Classification : Reducing Variance and Extracting Features

    Author : Isabella Reinhold; Statistical Signal Processing Group; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multifönster; Tids-frekvensanalys; Instantaneous frequency; Multitaper; Signal resolution; Reassignment method; Time-frequency analysis;

    Abstract : Spectral analysis encompasses several powerful signal processing methods. The papers in this thesis present methods for finding good spectral representations, and methods both for stationary and non-stationary signals are considered. READ MORE
