  1. 1. Estimation Using Low Rank Signal Models

    Författare :Kaushik Mahata; Torsten Söderström; Mats Viberg; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; parameter estimation; separable least squares; statistical analysis; viscoelasticity; subspace algorithms; spectrum estimation; Signal processing; Signalbehandling;

    Sammanfattning : Designing estimators based on low rank signal models is a common practice in signal processing. Some of these estimators are designed to use a single low rank snapshot vector, while others employ multiple snapshots. This dissertation deals with both these cases in different contexts. LÄS MER

  3. 2. On computational methods for nonlinear estimation

    Författare :Thomas Schön; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nonlinear estimation; Particle filter; Kalman filter; System identification; Convex optimization; Differential-algebraic equation; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The Bayesian approach provides a rather powerful framework for handling nonlinear, as well as linear, estimation problems. We can in fact pose a general solution to the nonlinear estimation problem. However, in the general case there does not exist any closed-form solution and we are forced to use approximate techniques.

  4. 3. A convex optimization approach to complexity constrained analytic interpolation with applications to ARMA estimation and robust control

    Författare :Anders Blomqvist; Anders Lindquist; Giorgio Picci; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical optimization; systems theory; analytic interpolation; moment matching; Nevanlinna-Pick interpolation; spectral estimation; convex optimization; Optimeringslära; systemteori; Optimization; systems theory; Optimeringslära; systemteori;

    Sammanfattning : Analytical interpolation theory has several applications in systems and control. In particular, solutions of low degree, or more generally of low complexity, are of special interest since they allow for synthesis of simpler systems. LÄS MER

  5. 4. Order restricted inference over countable preordered sets. Statistical aspects of neutron detection

    Författare :Vladimir Pastukhov; Matematisk statistik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Constrained inference; Isotonic regression; Density estimation; Grenander estimator; Limit distribution; Neutron detection;

    Sammanfattning : This thesis consists of four papers. In the first paper, we study the isotonic regression estimator over a general countable preordered set. We obtain the limiting distribution of the estimator and study its properties. Also, it is shown that the isotonisation preserves the rate of convergence of the underlying estimator. LÄS MER

  7. 5. Decentralized Estimation Using Conservative Information Extraction

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Sensor networks consist of sensors (e.g., radar and cameras) and processing units (e.g. LÄS MER
