  1. 6. Parameter Estimation of a DOC from Engine Rig Experiments

    Författare :Björn Lundberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multivariate Data Analysis; Parameter Estimation; Exhaust Aftertreatment Modeling; Design of Experiments; Engine Test Bench; DOC; Full Scale;

    Sammanfattning : In this thesis methods of parameter estimation of a Diesel Oxidation Catalyst (DOC) from engine rig experiments were investigated. The investigation did not only include methods of parameter fitting to experimental data but a large effort was also put into catalyst modeling and experimental design. LÄS MER

  3. 7. Contributions to quantitative dynamic contrast-enhanced MRI

    Författare :Anders Garpebring; Mikael Karlsson; Ronnie Wirestam; Nils Östlund; Jón Hauksson; Steven Sourbron; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamic contrast-enhanced MRI; quantitative imaging; parameter estimation; uncertainty estimation; arterial input function; radiofysik; radiation physics;

    Sammanfattning : Background: Dynamic contrast-enhanced MRI (DCE-MRI) has the potential to produce images of physiological quantities such as blood flow, blood vessel volume fraction, and blood vessel permeability. Such information is highly valuable, e.g., in oncology. LÄS MER

  4. 8. On Multidimensional Dynamic Fluorescence Imaging and Quantitative Image Analysis in Wide-Field Microscopy Applications to Studies of Astroglial Cells

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; volume estimation; astrocyte; calcium wave; intercellular signaling; volumetric image analysis; fluorescence imaging; three-dimensional 3D reconstruction; segmentation;

    Sammanfattning : Modern biological research has benefited from a renaissance in light microscopy, brought about by the convergence of developments in fields as diverse as electronics, optics, molecular biology, computer science, and reagent chemistry. Integration of these has transformed microscopy into a highly useful, dynamic research tool for biology and medicine. LÄS MER

  5. 9. Aspects of pediatric hemodynamics. A study of young children undergoing corrective heart surgery

    Författare :Theódór Sigurdsson; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiac output; Heart surgery; Hemodynamics; Intracardiac shunt; Volume estimation; Young children;

    Sammanfattning : AbstractBackground: Assessing critically ill patients is demanding because their clinical signs are not always easy to interpret. This is particularly true for pediatric patients, due to their small size and robust circulatory compensatorymechanism. LÄS MER
