  1. 21. Efficient Methods for Direct Volume Rendering of Large Data Sets

    Författare :Patric Ljung; Anders Ynnerman; Thomas Ertl; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Graphics; Scientific Visualization; Medical Imaging; Volume Rendering; Raycasting; Transfer Functions; Level-of-detail; Fuzzy Classification; Virtual Autopsies; Computer science; Datavetenskap;

    Sammanfattning : Direct Volume Rendering (DVR) is a technique for creating images directly from a representation of a function defined over a three-dimensional domain. The technique has many application fields, such as scientific visualization and medical imaging. LÄS MER

  2. 22. High Resolution Analysis of Halftone Prints : A Colorimetric and Multispectral Study

    Författare :Daniel Nyström; Björn Kruse; Markku Hauta- Kasari; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Color imaging; Multispectral imaging; Halftone print; Dot gain; Image analysis; Bildanalys;

    Sammanfattning : To reproduce color images in print, the continuous tone image is first transformed into a binary halftone image, producing various colors by discrete dots with varying area coverage. In halftone prints on paper, physical and optical dot gains generally occur, making the print look darker than expected, and making the modeling of halftone color reproduction a challenge. LÄS MER

  3. 23. Thermometry Using Laser-Induced Emission from Thermographic Phosphors: Development and Applications in Combustion

    Författare :Alaa Omrane; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; framdrivningssystem; Motorer; Motors and propulsion systems; Laser technology; Laserteknik; Teknik; Technological sciences; Physics; Pyrolysis; Flame spread; Droplet; Engine; Imaging; Temperature; Thermographic phosphors; Combustion; Fysik; Laser diagnostics;

    Sammanfattning : Temperature is a fundamental thermodynamic parameter used to describe physical, chemical and biological processes. Much effort is made to measure temperature accurately in a wide variety of applications, making temperature one of the most extensively measured parameters. LÄS MER

  4. 24. Injection and Combustion of Alternative Fuels in Spark Ignited Direct Injection Engines

    Författare :Lars Christian Riis Johansen; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gas fuel; direct injection; E85; stratified combustion; spark ignition; alternative fuels; optical measurements;

    Sammanfattning : Increasingly stringent vehicle emission legislation necessitates increasingly efficient combustion engines. The use of direct injection in spark ignited engines improves engine efficiency and reduces CO2 emissions. LÄS MER

  5. 25. Affibody-mediated targeting of HER-family receptors for cancer imaging and therapy

    Författare :Charles Dahlsson Leitao; Stefan Ståhl; John Löfblom; Christoph Rader; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cancer therapy; radionuclide imaging; affibody molecules; HER-receptors; prodrug; protein design; Cancerterapi; radionuklidavbildning; affibody molekyler; HER-receptorer; prodrog; proteindesign; Bioteknologi; Biotechnology;

    Sammanfattning : Proteins are remarkable molecules with diverse and specialized functions playing essential roles in most biological processes. One such function is protecting us from diseases by the action of antibodies in our immune system that can recognize and mediate the destruction of invading pathogens by binding to foreign epitopes found on non-self proteins.
