  1. 21. Automated sleep scoring using unsupervised learning of meta-features

    University essay from KTH/Skolan för datavetenskap och kommunikation (CSC)

    Author : Sebastian Olsson; [2016]
    Keywords : EEG; sleep scoring; support vector machines; deep belief networks; AASM; unsupervised learning; feature extraction; genetic algorithms; meta-features;

    Abstract : Sleep is an important part of life as it affects the performance of one's activities during all awake hours. The study of sleep and wakefulness is therefore of great interest, particularly to the clinical and medical fields where sleep disorders are diagnosed. When studying sleep, it is common to talk about different types, or stages, of sleep. READ MORE

  3. 22. Diode laser spectroscopy for oxygen detection in the lungs of infants

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Atomfysik

    Author : Peilang Liao; [2016]
    Keywords : GASMAS; Tunable laser; Transport theory; 3D phantom; Diagnoses; Gas; Lung; Physics and Astronomy;

    Abstract : This thesis work is part of a larger project with final goal to be able to measure the oxygen concentration in the lungs of infants, using non-invasive laser spectroscopy. This thesis is specifically dealing with simulations of light transport through the upper body of infants, as well as constructing a tissue-like model (phantom) that can be used in experiments.

  4. 23. Developing a soprano classifier using FIR-ELM neural network

    University essay from Mälardalens högskola/Akademin för innovation, design och teknik

    Author : Peter Cederblad; [2016]
    Keywords : FIR-ELM; Audio decomposition; Soprano classifier;

    Abstract : This thesis aims at investigate the feasibility of classifying the soprano singing voice type using a single layer neural network trained with the FIR-ELM algorithm after that the monaural auditory mixture has been segmented with the Harmonic, Percussive and Residual, HPR, decomposition algorithm, previously introduced by Driedger et al.Two different decomposition structures has been evaluated both based on the same HPR decomposition technique.

  5. 24. Processing of Optical Coherence Tomography Images : Filtering and Segmentation of Pathological Thyroid Tissue

    University essay from Linköpings universitet/Institutionen för medicinsk teknik; Linköpings universitet/Medicinska fakulteten

    Author : Daniela Koller; [2016]
    Keywords : ;

    Abstract : In the human body, the main function of the healthy thyroid gland is the regulation of the metabolism and hormone production. Included in the thyroid are organized structured and uniformly shaped follicles ranging from 50-500 μm in diameter. READ MORE

  6. 25. Baking And Compression For Dynamic Lighting Data

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Tom Olsson; [2015]
    Keywords : ;

    Abstract : This report describes the development and prototype implementation of a method for baking and compression of lightmaps, in an environment with dynamic lights. The method described can achieve more than 95 % compression eciency, and can be easily tuned with only two parameters. READ MORE
