  1. 1. Estimation and detection of transmission line characteristics in the copper access network

    Author : Fredrik Lindqvist; Lunds universitet.; Lund University.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Digital subscriber line; DSL; line qualification; twisted-pair line; copper access network; cable modeling; crosstalk channel estimation; estimation; detection;

    Abstract : The copper access-network operators face the challenge of developing and maintaining cost-effective digital subscriber line (DSL) services that are competitive to other broadband access technologies. The way forward is dictated by the demand of ever increasing data rates on the twisted-pair copper lines. READ MORE

    Abstract : Tactile perception is considered an important contributor to the overall consumer experience of a product. However, what physical properties that create the specifics of tactile perception, are still not completely understood. READ MORE

  3. 3. Curvature Estimation and Description

    University dissertation from Linköping, Sweden : Linköping University, Department of Electrical Engineering

    Author : Håkan Bårman; Linköpings universitet.; Linköpings universitet.; [1989]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : This paper presents a new method for detection and estimation of curvature. The algorithm is implemented in the hierarchical feature pyramid proposed in the GOP concept. Curvature is handled at the second level of the pyramid with a vector field description of the orientation of the image as input. READ MORE

  4. 4. Contributions to quantitative dynamic contrast-enhanced MRI

    University dissertation from Umeå : Umeå Universitet

    Author : Anders Garpebring; Umeå universitet.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamic contrast-enhanced MRI; quantitative imaging; parameter estimation; uncertainty estimation; arterial input function; radiofysik; radiofysik;

    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

  5. 5. Tactile Perception - Role of Physical Properties

    University dissertation from Stockholm : KTH

    Author : Lisa Skedung; KTH.; [2010]
    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.; MEDICINE Chemistry; MEDICIN 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
