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

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Gunnar Läthén; Linköpings universitet.; Linköpings universitet.; Linköpings universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Image segmentation; Medical image analysis; Level set method; Quadrature filter; Multi-scale; TECHNOLOGY Information technology Image analysis; TEKNIKVETENSKAP Informationsteknik Bildanalys;

    Abstract : 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.

  2. 2. Numerical simulation of multi-scale transport processes and reactions in pem fuel cells using two-phase models

    University dissertation from Lunds tekniska högskola, Institutionen för värme- och kraftteknik

    Author : Munir Khan; Jinliang Yuan; Bengt Sundén; Lunds universitet.; Lund University.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; numerical analysis; multi-scale; multi-phase; reacting flows; multi-component;

    Abstract : A numerical study for the cathode of a PEM fuel cell has been performed in this study. The results have been limited to cathode only because, in PEM fuel cells, the oxygen reduction reactions, ORRs, are considered the rate limiting reactions and govern the fuel cell performance.

  3. 3. Novel Multi-Scale Modeling Framework for Structure and Transport in Complex Battery Electrolytes

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Rasmus Andersson; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; hierarchical analysis; electrolytes; force field development; molecular dynamics; non-vehicular transport; multi-scale method; Lithium-ion batteries; genetic algorithms;

    Abstract : Affordable high energy rechargeable batteries are crucial for further electrification of the transport sector, which is necessary in order to contribute to limit our CO2 emissions to acceptable levels. While today’s lithium-ion batteries (LIBs) have indeed initiated the electrification of the transportation section successfully, electric vehicles are still expensive and typically have ranges limited to ca.

  4. 4. Multi-scale feature tracking and motion estimation

    University dissertation from Stockholm : KTH

    Author : Lars Bretzner; KTH.; [1999]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : This thesis studies the problems of feature tracking and motion estimation andpresents an application of these concepts to human-computer interaction. Thepresentation is divided into three parts.The first part addresses feature tracking in a multi-scale context. READ MORE

  5. 5. A Multi-Scale Approach To Adhesive Mixing

    University dissertation from Stockholm : KTH
