  2. 6. Contributions to quantitative dynamic contrast-enhanced MRI

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

    Abstract : 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. READ MORE

  4. 7. Tactile Perception - Role of Physical Properties

    Author : Lisa Skedung; Mark Rutland; Katrin Danerlöv; Sören Andersson; Ann Maria Cornell; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Finger Friction; Skin Friction; Paper Friction; Friction Coefficient; Piezoelectric Force Sensor; Skin Tribology; Biotribology; Soft Tribology; Surface Roughness; Profilometry; Coated Paper; Uncoated Paper; Printing Paper; Magazine Paper; Tactile Perception; Psychophysics; Multidimensional Scaling; Magnitude Estimation; Paper Coarseness; Thermal Conductivity; X-ray Photoelectron Spectroscopy.; Chemistry; Kemi;

    Abstract : The aim of this thesis is to interconnect human tactile perception with various physical properties of materials. Tactile perception necessitates contact and relative motion between the skin and the surfaces of interest. READ MORE

  5. 8. Global Pose Estimation from Aerial Images : Registration with Elevation Models

    Author : Bertil Grelsson; Michael Felsberg; Per-Erik Forssén; Kalle Åström; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Over the last decade, the use of unmanned aerial vehicles (UAVs) has increased drastically. Originally, the use of these aircraft was mainly military, but today many civil applications have emerged. READ MORE

  6. 9. Varince component estimation in geodetic networks

    Author : Tomas Egeltoft; Lars Sjöberg; []
    Keywords : ;

    Abstract : A summary of some of the existing variance component estimators are given, namely the MINQE, the IMINQ, the general case of BQUNE (best Quardratic Unbiased Non negative Estimator), the Helmert estimators, the Förstner estimator and the Kubik estimator. A derivation of a special case of the BQUNE is made. READ MORE

  7. 10. Optical Performance Monitoring in Digital Coherent Communications: Intelligent Error Vector Magnitude Estimation
