  1. 21. Statistical Segmentation and Registration of Medical Ultrasound Data

    Författare :Mattias Hansson; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Registration; Segmentation; Feature descriptor; Statistical image and signal processing; Medical ultrasound; Variational methods; Mixture model; Bayesian; Markov Chain Monte Carlo; Similarity measur;

    Sammanfattning : The interpretation of ultrasonic imagery is typically not straightforward and of quite subjective nature and therefore strongly dependent on the expertise of its users. Thus the development of algorithms which aid in the interpretation of ultrasonic data is a highly relevant topic. LÄS MER

  3. 22. Spatial Decompositions of a Fully-developed Turbulent Round Jet Sampled with Particle Image Velocimetry

    Författare :Maja Wänström; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; proper orthogonal decomposition; axisymmetric turbulent jet; PIV; spatial spectral analysis; equilibrium similarity;

    Sammanfattning : Spatial decompositions of the turbulence in a far, axisymmetric jet at exit Reynolds number of 20, 000 have been performed. Equilibrium similaritytheory applied to the two-point Reynolds stresses has shown that the turbulence statistics in the far, fully developed region of an axisymmetric jet should be independent of origin in the streamwise direction when evaluated on the similarity coordinates system.

  4. 23. Predicting who stays or leaves after the acquisition: : Target’s top manager turnover

    Författare :Keivan Aghasi; Terrence Brown; Massimo Colombo; Maureen McKelvey; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Acquisition; CEO turnover; TMT turnover; coordination; Founder-CEO; Similarity attraction; Diversity;

    Sammanfattning : In acquisition of high-tech and knowledge intensive firms, scholars have paid special attention to top managers’ status after the deal. Literature suggests that these managers in particular CEOs if kept in post-acquisition provide coordination capacity for the acquirer to transfer the knowledge and technology from the target to the acquirer while minimizing the disruptive effect of post-acquisition integration process.

  5. 24. Comparison and Tracking Methods for Interactive Visualization of Topological Structures in Scalar Fields

    Författare :Himangshu Saikia; Tino Weinkauf; Filip Sadlo; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; topology; scalar fields; merge tree; tree comparison; tracking; similarity search; Computer Science; Datalogi;

    Sammanfattning : Scalar fields occur quite commonly in several application areas in both static and time-dependent forms. Hence a proper visualization of scalar fieldsneeds to be equipped with tools to extract and focus on important features of the data. LÄS MER

  7. 25. Scalable Machine Learning through Approximation and Distributed Computing

    Författare :Theodore Vasiloudis; Anders Holst; Henrik Boström; Seif Haridi; Daniel Gillblad; Indre Žliobaitė; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Online Learning; Distributed Computing; Graph Similarity; Decision Trees; Gradient Boosting;

    Sammanfattning : Machine learning algorithms are now being deployed in practically all areas of our lives. Part of this success can be attributed to the ability to learn complex representations from massive datasets. LÄS MER
