  1. 1. Computer methods for voice analysis

    University dissertation from Stockholm : KTH

    Author : Svante Granqvist; KTH.; [2003]
    Keywords : voice analysis; perceptual analysis; fundamental frequency; correlogram; aperiodicity; Fourier analysis; high-speed imaging; laryngoscopy; vocal fold vibration; voice accumulation.; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : This thesis consists of five articles and a summary. Thethesis deals with methods for measuring properties of thevoice. The methods are all computer-based, but utilisedifferent approaches for measuring different aspects of thevoice.Paper I introduces the Visual Sort and Rate (VSR) method forperceptual rating of voice quality.

  2. 2. Dynamic Programming for Ultrasound Image Analysis of Atherosclerosis

    University dissertation from Chalmers University of Technology

    Author : Peter Holdfeldt; Chalmers tekniska högskola.; Chalmers University of Technology.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bildanalys; Image analysis; atherosclerotic plaque; carotid artery; classification; dynamic programming; edge detection; graph cuts; image analysis; ultrasound;

    Abstract : Cardiovascular diseases, due to atherosclerosis, are among the most common causes of death in the industrialized world. Atherosclerotic plaque composition as well as arterial diameter and wall thickness can be used to predict the risk of cardiovascular disease. These risk factors can be assessed non-invasively by ultrasound. READ MORE

  3. 3. Computational Medical Image Analysis : With a Focus on Real-Time fMRI and Non-Parametric Statistics

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Anders Eklund; Linköpings universitet.; Linköpings universitet.; Linköpings universitet.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; functional magnetic resonance imaging; brain computer interfaces; canonical correlation analysis; random permutation test; graphics processing unit;

    Abstract : Functional magnetic resonance imaging (fMRI) is a prime example of multi-disciplinary research. Without the beautiful physics of MRI, there wouldnot be any images to look at in the first place. To obtain images of goodquality, it is necessary to fully understand the concepts of the frequencydomain. READ MORE

    Abstract : The aim of this thesis is to model and describe dynamical events for biological cells using statistical and mathematical tools. The thesis includes five papers that all relate to stochastic modelling of cells. READ MORE

  5. 5. Analysis of melanins

    University dissertation from Gerd Odh Olsson, Dept of Pharmacology, Sölveg 10, S-223 62 Lund, Sweden

    Author : Gerd Odh Olsson; Lunds universitet.; Lund University.; [1998]
    Keywords : PPT-I; PPT-II; DDT; MIF; tyrosinase related protein. dopachrome tautomerase; 3-dicarboxylic acid; pyrrole-2; 5-tricarboxylic acid; 3; thiazole-4; 5-dicarboxylic acid; Pharmacological sciences; pharmacognosy; pharmacy; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi; MEDICIN; MEDICINE;

    Abstract : Mammalian melanins are of two major types, eumelanins and peheomelanins, which often occur together, then called mixed-type melanins. A method has been developed for analysing the various forms of melanins. READ MORE
