  3. 2. Linear Control and Estimation Using Operator Factorization

    Författare :Per Hagander; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The filtering, prediction and smoothing problems as well as the linear quadratic control problems can very generally be formulated as operator equations using basic linear algebra. The equations are of Fredholm type II and difficult to solve directly. LÄS MER

  4. 3. Boundary Detection in Cardiovascular Ultrasonic Images Based on Multiscale Dynamic Programming

    Författare :Quan Liang; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multiscale dynamic programming; artery measurement; cardiac measurement; edge-preserving smoothing; ultrasonic imaging; boundary detection;

    Sammanfattning : Non-invasive ultrasonic imaging is widely used in cardiovascular studies as well as clinical diagnostics. This is due to its non-invasiveness, low cost and easy operation. However, ultrasonic images are noisy and present artifacts, speckles, and echo dropouts. LÄS MER

  5. 4. Multigrid Preconditioners for the Discontinuous Galerkin Spectral Element Method : Construction and Analysis

    Författare :Lea Miko Versbach; Numerisk analys; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Discontinuous Galerkin Method; Finite Volume Method; Implicit Schemes; Local Fourier Analysis; Multigrid Method; Preconditioner; Space-Time Discretization; Spectral Element Method;

    Sammanfattning : Discontinuous Galerkin (DG) methods offer a great potential for simulations of turbulent and wall bounded flows with complex geometries since these high-order schemes offer a great potential in handling eddies. Recently, space-time DG methods have become more popular. LÄS MER

  7. 5. Reconstruction of geometric road data using remotely sensed imagery

    Författare :Dan Klang; KTH; []
