    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chip curl; Chip flow; Chip segmentation; Computed Tomography; Damage modeling; Flow stress modeling; Machining; Spånkrökning; Spånflöde; Spånsegmentering; Datortomografi; Skademodelleringen; Modellering av Flytspänning; Bearbetning; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : Within the manufacturing of metallic components, machining plays an important role and is of vital significance to ensure process reliability. From a cutting tool design perspective, physics-based numerical modeling that can predict chip morphology is highly necessary to design tool macro geometry. LÄS MER

  3. 18. Dynamic magnetic resonance imaging of the breast : Imaging features for diagnosis and prognosis of breast cancer

    Författare :Botond K Szabo; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Breast neoplasm; magnetic resonance imaging; prognostic factors; survival analysis; image segmentation; artificial neural networks;

    Sammanfattning : The general aim of the present thesis was to identify and study dynamic contrast-enhanced magnetic resonance imaging (CE-MRI) features that contribute to the diagnosis and may help in predicting prognosis in breast cancer. Study I studied the kinetic and morphological MR features and their diagnostic power were studied in a total of 92 women with 109 histopathologically verified breast lesions. LÄS MER

  4. 19. Template Based Recognition of On-Line Handwriting

    Författare :Jakob Sternby; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; on-line handwriting recognition segmentation dynamic programming clustering discriminative clustering;

    Sammanfattning : Software for recognition of handwriting has been available for several decades now and research on the subject have produced several different strategies for producing competitive recognition accuracies, especially in the case of isolated single characters. The problem of recognizing samples of handwriting with arbitrary connections between constituent characters (emph{unconstrained handwriting}) adds considerable complexity in form of the segmentation problem.

  5. 20. Virtual Full Replication for Scalable Distributed Real-Time Databases

    Författare :Gunnar Mathiason; Sten F. Andler; Sang H. Son; Hans Hansson; Alejandro Buchmann; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; Scalability; Flexibility; Adaptiveness; Database Replication; Resource Management; Distributed Database; Real-time Database; Computer science; Datalogi; Information technology; Informationsteknik; Teknik; Technology;

    Sammanfattning : A fully replicated distributed real-time database provides high availability and predictable access times, independent of user location, since all the data is available at each node. However, full replication requires that all updates are replicated to every node, resulting in exponential growth of bandwidth and processing demands with the number of nodes and objects added.
