2. 11. Subspace Methods for System Identification and Signal Processing

   Author : Tony Gustafsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The main theme of this thesis is black-box mathematical modeling of discrete-time, finite-dimensional, and linear dynamical systems, i.e. system identification. The thesis addresses both systems with and without exogenous inputs. READ MORE

4. 12. Subspace Fitting Concepts in Sensor Array Processing

   Author : Mats Viberg; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Subspace fitting; Sensor array processing;

   Abstract : The area of sensor array processing has recently received considerable attention in the litterature. Much interest stems from the potential of applying advanced concepts from signal processing to a variety of real-world problems. READ MORE

5. 13. Subspace-Based Parameter Estimation Problems in Signal Processing

   Author : Joakim Sorelius; Torsten Söderström; Peter Stoica; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sensor array processing; parameter estimation; spread spectrum communication; direct sequence CDMA; order estimation; subspace fitting; blind identification; system identification; Signal Processing; Signalbehandling;

   Abstract : The effects of multipath-induced angular spread and non-zero band-width on narrow-band direction-of-arrival (DOA) estimation are investigated. In both cases expressions for the resulting estimation error are developed for the MUSIC, ESPRIT and WSF DOA estimators. READ MORE

6. 14. Matrix Algebra for Quantum Chemistry

   Author : Emanuel H. Rubensson; Pawel Salek; Stefan Goedecker; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; linear scaling; reduced complexity; electronic structure; density functional theory; Hartree-Fock; density matrix purification; congruence transformation; inverse factorization; eigenvalues; eigenvectors; numerical linear algebra; occupied subspace; canonical angles; invariant subspace; Theoretical chemistry; Teoretisk kemi;

   Abstract : This thesis concerns methods of reduced complexity for electronic structure calculations.  When quantum chemistry methods are applied to large systems, it is important to optimally use computer resources and only store data and perform operations that contribute to the overall accuracy.

7. 15. Models and Algorithms - with applications to vehicle tracking and frequency estimation

   Author : Joakim Gunnarsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; motion models; subspace methods; radar detections; Automotive; F-ESPRIT.; vehicle tracking; frequency estimation;

   Abstract : This thesis considers two different research problems; one concerned with the issue of tracking vehicles and one related to estimating frequencies in harmonic signals. The vehicle-tracking problem is addressed from the perspective of an automotive-safety application, which seeks to monitor the course of surrounding road users with the objective to make decisions regarding if, how and when to intervene.
