  1. 1. Segmentation Methods for Medical Image Analysis : Blood vessels, multi-scale filtering and level set methods

    Författare :Gunnar Läthén; Reiner Lenz; Niels Christian Overgaard; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Image segmentation; Medical image analysis; Level set method; Quadrature filter; Multi-scale; Image analysis; Bildanalys;

    Sammanfattning : Image segmentation is the problem of partitioning an image into meaningful parts, often consisting of an object and background. As an important part of many imaging applications, e.g. face recognition, tracking of moving cars and people etc, it is of general interest to design robust and fast segmentation algorithms. LÄS MER

  3. 2. Aiming at Moving Targets : Applying Cognitive Work Analysis to Work Domains in Transition

    Författare :Ida Löscher; Anders Arweström Jansson; Åsa Cajander; Camilla Fröjd; Stas Krupenia; Catherine Burns; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cognitive work analysis; work domain analysis; control task analysis; strategies analysis; abstraction hierarchy; contextual activity template; activity prioritization; systems design; heavy vehicle development; long haul trucks; intensive care; nursing; digitalization.; Computer Science with specialization in Human-Computer Interaction; Datavetenskap med inriktning mot människa-datorinteraktion;

    Sammanfattning : The design of IT systems for complex work environments is essential for workers to be able to operate more effectively and efficiently. To design a system that supports the workers' specific tasks we need to understand the work demands and the context in which the system operates. LÄS MER

  4. 3. Precise Image-Based Measurements through Irregular Sampling

    Författare :Teo Asplund; Robin Strand; Cris L. Luengo Hendriks; Matthew J. Thurley; Gunilla Borgefors; Hugues Talbot; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; image analysis; image processing; mathematical morphology; irregular sampling; adaptive morphology; missing samples; continuous morphology; path opening.; Computerized Image Processing; Datoriserad bildbehandling;

    Sammanfattning : Mathematical morphology is a theory that is applicable broadly in signal processing, but in this thesis we focus mainly on image data. Fundamental concepts of morphology include the structuring element and the four operators: dilation, erosion, closing, and opening. LÄS MER

  5. 4. A moving boundary problem for capturing the penetration of diffusant concentration into rubbers : Modeling, simulation and analysis

    Författare :Surendra Nepal; Adrian Muntean; Yosief Wondmagegne; Magnus Ögren; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Moving boundary problem; finite element method; a priori error estimate; a posteriori error estimate; order of convergence; diffusion of chemicals into rubber; swelling; Matematik; Mathematics;

    Sammanfattning : We propose a moving-boundary scenario to model the penetration of diffusants into rubbers. Immobilizing the moving boundary by using the well-known Landau transformation transforms the original governing equations into new equations posed in a fixed domain. LÄS MER

  7. 5. Safety Analysis of Systems-of-Systems

    Författare :Stephan Baumgart; Joakim Fröberg; Sasikumar Punnekkat; Iain Bate; Mälardalens universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System-of-Systems; Safety Analysis; Hazard Analysis; Model-based Development; Computer Science; datavetenskap;

    Sammanfattning : Safety-critical systems may fail dangerously with severe consequences to the health of the involved humans, costly equipment, the environment, or other valuable assets of a stakeholder. For these classes of systems, the developers are obliged to analyze each potentially hazardous situation thoroughly. LÄS MER
