  1. 1. Efficient Medical Volume Visualization : An Approach Based on Domain Knowledge

    Författare :Claes Lundström; Anders Ynnerman; Hans Knutsson; Dirk Bartz; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Scientific Visualization; Medical Imaging; Computer Graphics; Volume Rendering; Transfer Function; Level-of-detail; Fuzzy Classification; Uncertainty Visualization; Virtual Autopsies; Medical engineering; Medicinsk teknik;

    Sammanfattning : Direct Volume Rendering (DVR) is a visualization technique that has proved to be a very powerful tool in many scientific visualization applications. Diagnostic medical imaging is one domain where DVR could provide clear benefits in terms of unprecedented possibilities for analysis of complex cases and highly efficient work flow for certain routine examinations.

  2. 2. Macroscopic Volume and Free Volume of Polymer Blends and Pressure-densified Polymers

    Författare :Marcus Schmidt; Chalmers University of Technology; []
    Nyckelord :free-volume theories; refractive index; Lorentz-Lorenz equation; loss tangent; Avrami equation; freezing fractions; copolymers; polymer blends; pressure dilatometry; Tait equation of state; free-volume distributions; pressure-densified polymers; entropy of melting; dynamic-mechanical analysis; positronium; positron annihilation; free volume; cavity size; polymers; bulk modulus; PVT; phase separation; compressibility; thermal expansivity;

    Sammanfattning : The macroscopic volume V as a function of pressure P and temperature T is obtained from PVT measurements. PVT data is sensitive to the state of polymers and changes therein. Moreover, PVT data gives access to the free-volume fraction. LÄS MER

  3. 3. BitTorrent Traffic Measurements and Models

    Författare :David Erman; Blekinge Tekniska Högskola; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Peer-to-peer; traffic measurements; traffic modelling;

    Sammanfattning : The Internet has experienced two major revolutions. The first was the emergence of the World Wide Web, which catapulted the Internet from being a scientific and academic network to becoming part of the societal infrastructure. The second revolution was the appearance of the Peer-to-Peer (P2P) applications, spear-headed by Napster. LÄS MER

  4. 4. Liver metastases from colorectal cancer. Different strategies and outcomes

    Författare :Valentinus Valdimarsson; Lund Kirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Liver metastases; Colorectal Neoplasms; Hepatectomy; Mortality; Treatment outcome; Retrospective studies; Sweden; Registries; Volume measurements; Repeat hepatectomy; liver surgery; Functional liver volume; Repeated operation; Recurrence;

    Sammanfattning : Patients with colorectal liver metastases (CRLM) increasingly undergo liver resections. The belief is that the resection or ablation of a tumor, when possible, is the only possibility of a cure. LÄS MER

  5. 5. Free Volume Determination in Polymers and Polymer Blends

    Författare :Camilla Wästlund; Chalmers University of Technology; []
    Nyckelord :positronium formation; crystallinity; polymer blends; inhibition; polymers; free volume; positron annihilation; phase separation; distribution;

    Sammanfattning : The free volume of a polymer, which corresponds to the unoccupied regions accessible to segmental motions, is an important parameter for understanding and predicting many of its characteristic properties. The concept of free volume is the basis for understanding the molecular mobility in polymers. LÄS MER
