  2. 1. Analysis of Human Brain MRI Contributions to Regional Volume Studies

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Richard Nordenskjöld; Uppsala universitet.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MRI; Brain; Volume; Hemisphere; Intracranial volume; Image analysis; Datoriserad bildanalys; Computerized Image Analysis;

    Abstract : Many disorders are associated with regional brain volumes. The analysis of these volumes from MR images often requires sequential processing steps such as localization and delineation. READ MORE

  4. 2. Free Volume and Mesopores in Polymer Nanocomposites

    University dissertation from KFS AB

    Author : Petra Winberg; Lunds universitet.; Lund University.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemical technology and engineering; Kompositmaterial; Composite materials; Macromolecular chemistry; permeability ; membrane ; positron annihilation ; fumed silica ; clay ; mesopores ; polymer nanocomposites ; free volume ; Kemiteknik och kemisk teknologi; Makromolekylär kemi;

    Abstract : Popular Abstract in Swedish Den fria volymen i en polymer är kopplad till flera fundamentala fysikaliska egenskaper som till exempel densitet, viskositet och gas diffusivitet. De fysikaliska egenskaperna hos polymerer i närheten av, eller i kontakt med, en solid yta har visats vara väsentligt olika dess bulkegenskaper. READ MORE

  5. 3. Water diffusion and free volume in hydrophilic polymers

    University dissertation from Department of Polymer & Materials Chemistry

    Abstract : Popular Abstract in Swedish Vid vattenabsorption i en polymer antas vattenmolekylerna röra sig genom polymeren via små kaviteter, som inte upptas av polymermolekylerna och dess termiska vibrationer. Den ej upptagna volymen, som de små kaviteterna representerar kallas fri volym. READ MORE

  6. 4. Foam, Fire and Free Volume - Chemical and Physical Aspects of Porous Polymers

    Abstract : Popular Abstract in Swedish Bilsäten har genomgått en kontinuerlig utveckling ända sedan de först beskrevs år 1885. På den tiden kunde man läsa om vadderade läderbänkar, monterade på stora fjädrar, fastsatta i chassit på ”hästlösa vagnar”. READ MORE

  7. 5. Efficient Medical Volume Visualization An Approach Based on Domain Knowledge

    University dissertation from Institutionen för teknik och naturvetenskap

    Author : Claes Lundström; Linköpings universitet.; Linköpings universitet.; [2007]
