  1. 1. The influence of solvent composition on crystal agglomeration of paracetamol

    Författare :Eva Ålander; KTH; []
    Nyckelord :paracetamol; solvent composition; agglomeration; image analysis; principal component analysis; agglomerate strength; interfacial energy;

    Sammanfattning : This thesis deals with the influence of solvent compositionon crystal agglomeration of paracetamol. Much work has beendone on characterisation of the crystalline product.Interfacial energies have also been determined for large singlegrown crystals. LÄS MER

  2. 2. Assessment of Body Composition Using Magnetic Resonance Imaging

    Författare :Joel Kullberg; Hans Frimmel; Tomas Gustavsson; Uppsala universitet; []
    Nyckelord :Bildanalys; Magnetic Resonance Imaging; Digital Image Processing; Segmentation; Morphology; Body Composition; Whole Body Imaging; Subcutaneous Adipose Tissue; Visceral Adipose Tissue; Anthropometry; Bildanalys;

    Sammanfattning : Methods for assessment of body composition allow studies of the complex relationships between body composition and the wellbeing of humans. The amount and distribution of adipose tissue is of great importance in these studies. LÄS MER

  3. 3. Non-image-forming effects of light : Implications for the design of living and working environments

    Författare :Mathias Adamsson; Thorbjörn Laike; Maria Johansson; Yvonne de Kort; Institutionen för arkitektur och byggd miljö; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; circadian rhythms; circannual; light exposure; melatonin; cortisol; sleep-wake behavior; perception; mood; spectral composition; measurement;

    Sammanfattning : Seasonal variation in mood and subjective well-being are common at geographical locations further away from the equator. The 24-h light-dark cycle is the main time cue for synchronizing the human circadian clock to the external day and night. LÄS MER

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

    Författare :Peter Holdfeldt; Chalmers University of Technology; []
    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

  5. 5. Influence of Composition and Pore Geometry on Immiscible Fluid Flow through Greensands: Development of Neutron Transmission Methods and Image Analysis

    Författare :Mikael Solymar; Chalmers University of Technology; []
    Nyckelord :pore geometry; image analysis; fluid flow; petrography; greensand; porosity; glauconite; permeability; neutron transmission methods; fluid saturation;

    Sammanfattning : The effect of the mineralogical composition and pore geometry of sediments on the distribution as well as the flow of immiscible fluids are of importance when evaluating petroleum reservoirs. Greensand containing the clay mineral glauconite is a complex reservoir rock type. LÄS MER
