  1. 1. Krylov Subspace Methods for Linear Systems, Eigenvalues and Model Order Reduction

    University dissertation from Göteborg : Chalmers University of Technology

    Author : Daniel Skoogh; Göteborgs universitet.; Gothenburg University.; [1998]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; eigenvalues; eigenvectors; sparse; parallel; rational; Krylov; shift; invert; Arnoldi; linear systems; iterative; model; reduction; passive; 65F15; 65F50; 65Y05; 65F10; 93A30; 93B40;

    Abstract : New variants of Krylov subspace methods for numerical solution of linear systems, eigenvalue, and model order reduction problems are described. A new method to solve linear systems of equations with several right-hand sides is described. READ MORE

  2. 2. FE/MALE asymmetries of gender and sexuality

    University dissertation from Göteborg : Chalmers University of Technology

    Author : Ann Kroon; Uppsala universitet.; [2007]
    Keywords : Sociology; transsexualism; gender; sexuality; masculinity; femininity; asymmetries; gender order; Sociologi; Sociology; sociologi;

    Abstract : This thesis elicits logic of gender and sexuality from modern written material on psychiatric assessment of transsexualism in Sweden. Asymmetries of gender and sexuality with regard to females vs. males are analysed. READ MORE

  3. 3. From microstructure to subsurface characterization. Spectral information from field scale time domain induced polarization

    University dissertation from Lunds Universitet. Teknisk Geologi

    Author : Sara Johansson; Lund University.; Lunds universitet.; [2016-01-26]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geofysik; Inducerad Polarisation;

    Abstract : A large variety of subsurface infrastructure projects of different types can gain valuable information from tomographic measurements of subsurface physical properties. With resistivity and time domain spectral induced polarization (IP), the distributions of the conductive and capacitive properties of the subsurface are obtained. READ MORE

  4. 4. Inverse system identification with applications in predistortion

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Ylva Jung; Linköpings universitet.; Linköpings universitet.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; system identification; inverse models; signal processing; power amplifiers; predistortion; communication electronics;

    Abstract : Models are commonly used to simulate events and processes, and can be constructed from measured data using system identification. The common way is to model the system from input to output, but in this thesis we want to obtain the inverse of the system. READ MORE

  5. 5. Spatial inference for non-lattice data using Markov Random fields

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Linda Werner Hartman; Lund University.; Lunds universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis deals with how computationally effective lattice models could be used for inference of data with a continuous spatial index. The fundamental idea is to approximate a Gaussian field with a Gaussian Markov random field (GMRF) on a lattice. READ MORE
