  1. 1. Topics in multifractal measures, nonparametrics and biostatistics

    Författare :Attila Frigyesi; Anestesiologi och intensivvård; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; confidence interval; mixed effects; Statistics; operations research; programming; actuarial mathematics; Statistik; operationsanalys; programmering; aktuariematematik; operational model of pharmacological agonism; concentration-response curves; dose-response curves; ventilation perfusion scintigraphy; V Q-scan; pulmonary embolism; automated method; box counting; correlation dimension; Hentschel-Procaccia dimension; Rényi dimension; generalized dimensions; fractal dimension estimation; dimension spectrum; multifractal measures; kernel density estimates; absolute continuity; singular distribution functions;

    Sammanfattning : This thesis consists of four papers. The first two papers, which comprise the main part of the thesis, deal with an unexpected connection between kernel density estimators and dimension spectra for multifractal measures. LÄS MER

  3. 2. New Methods for Automated Interpretation of Electrocardiograms and Lung Scintigrams

    Författare :Holger Holst; Lund Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Decision Support System Clinical ; Image Processing Computer-Assisted ; Radionucleotide Imaging; Pulmonary Embolism; tomography; radiology; Neural Networks Computer ; Electrocardiography; Clinical physics; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

    Sammanfattning : The principal purposes of the studies reported in this thesis were to develop new methods to make computerised decision support systems in medicine both more reliable and fully automated. These aims were pursued in the belief that the solution to these problems will lead to an increased clinical use of such systems resulting in benefit to both patient and physician. LÄS MER

  4. 3. Caspase-3 in lens epithelium

    Författare :Nooshin Talebizadeh; Per Söderberg; Finn Hallböök; Konstantin Galichanin; Michael Wormstone; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ultraviolet radiation; caspase-3; lens; cataract; apoptosis; Immunohistochemistry; spatial distribution; time evolution; modelling; automatic analysis; cell counting; image analysis.; Ophtalmology; Oftalmiatrik;

    Sammanfattning : Purpose: To model the time evolution of active caspase-3 protein expression in a healthy lens, and in a lens exposed to UVR-300 nm (UVR-B). To develop an automated method to classify the fluorescent signal of biomarkers in the lens epithelial cells.Methods: Six-week old Sprague-Dawley rats were used. LÄS MER

  5. 4. Magnetic Resonance Imaging of Human Brown Adipose Tissue : Methodological Development and Application

    Författare :Elin Lundström; Joel Kullberg; Håkan Ahlström; Lars Johansson; Robin Strand; Sven Månsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Brown adipose tissue; Magnetic resonance imaging; Positron emission tomography; Image segmentation; Glucose metabolism;

    Sammanfattning : Brown adipose tissue (BAT) is a thermogenic organ with the main human depot located in the cervical-supraclavicular (sBAT) region. BAT is proposed as a potential therapeutic target for obesity and diabetes. LÄS MER

  7. 5. Dynamic Programming for Ultrasound Image Analysis of Atherosclerosis

    Författare :Peter Holdfeldt; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; atherosclerotic plaque; ultrasound; classification; dynamic programming; carotid artery; image analysis; edge detection; graph cuts;

    Sammanfattning : 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. LÄS MER
