1. 1. Recursive Bayesian Estimation : Navigation and Tracking Applications

   Författare :Niclas Bergman; Fredrik Gustafsson; Lennart Ljung; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Target tracking; Autonomous aircraft navigation; Terrain navigation;

   Sammanfattning : Recursive estimation deals with the problem of extracting information about parameters, or states, of a dynamical system in real time, given noisy measurements of the system output. Recursive estimation plays a central role in many applications of signal processing, system identification and automatic control. LÄS MER

3. 2. Recursive Blocked Algorithms, Data Structures, and High-Performance Software for Solving Linear Systems and Matrix Equations

   Författare :Isak Jonsson; Bo Kågström; Zhaojun Bai; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datorberäkningar och högpresterande datorer; Recursive algorithm; recursive blocked format; Cholesky factorization; Sylvester-type equations; automatic blocking; superscalar; GEMM-based; RECSY library; Datorberäkningar och högpresterande datorer; Computer engineering; Datorteknik; business data processing; administrativ databehandling;

   Sammanfattning : This thesis deals with the development of efficient and reliable algorithms and library software for factorizing matrices and solving matrix equations on high-performance computer systems. The architectures of today's computers consist of multiple processors, each with multiple functional units. LÄS MER

4. 3. Identification, Diagnosis, and Control of a Flexible Robot Arm

   Författare :Måns Östring; Svante Gunnarsson; Mikael Norrlöf; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Identification; Robot; Flexible; Diagnosis; Control; LQG; Recursive;

   Sammanfattning : The most important factors in manufacturing are quality, cost, and productivity. The trend is towards lighter robots with increased mechanical flexibilities, and therefore there is a need to include the flexibilities in the robot models to obtain good performance of the robot.

5. 4. On Speech-to-Text Alignment, Phonetic Labeling, and Recursive Signal Processing

   Författare :Åke Andersson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phonetic labeling; recursive algorithms; adaptive algorithms; speech-to-text alignment; dynamic programming; time-varying systems; subspace tracking; time-alignment; parameter estimation; time-warping;

   Sammanfattning : Speech data-bases are an important issue in the study of speech communication. In particular, time-aligned and phonetically labeled speech data-bases are useful during the design of applications such as speech recognizers. The time-alignment and labeling of the speech data is traditionally done manually. LÄS MER

7. 5. Recursive Methods in Urn Models and First-Passage Percolation

   Författare :Henrik Renlund; Sven Erick Alm; Svante Janson; John Wierman; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; stochastic approximation algorithm; generalized Polya urn; limit theorem; first-passage percolation; rate of percolation; time constant; Mathematical statistics; Matematisk statistik; Mathematical Statistics; Matematisk statistik;

   Sammanfattning : This PhD thesis consists of a summary and four papers which deal with stochastic approximation algorithms and first-passage percolation. Paper I deals with the a.s. limiting properties of bounded stochastic approximation algorithms in relation to the equilibrium points of the drift function. LÄS MER
