I have developed a regularized version of Burg algorithm via a regularized Burg reflexion coefficient. I have regularized EVD (Eigen Value Decomposition) of Complex Toeplitz Hermitian matrix with a recursive (rank-one modification of successive matrices), EVD algorithm and regularized reflexion coefficients. These methods have been described in papers published in GRETSI-95, EUSIPCO-96, ICASSP-97 and GRETSI-97. If you work also in regularization methods applied to spectrum analysis,could you sent me information by post or e-mail at the following address : Frederic BARBARESCO THOMSON-CSF AIRSYS RD/RAN Radar Unit Algorithms & New Concepts Department 7/9, rue des Mathurins 92221, BAGNEUX Cedex FRANCE phone : 33.1.40.84.20.04 fax : 33.1.40.84.36.31 E-mail : barbaresco@airsys.thomson.fr ------------------------------ From: pointltd@glasnet.ru Subject: Inverse Problems Technique for the Complex Processes Analysis Date: Mon, 23 Jun 1997 Dear colleagues! In previous IPNet Digest Vol.4, No.3,4,5 theoretical substantiation of significant informatibiality increase for experiment processing is submitted. What does it give practically? For experimental research, when measurements are limited it permits to carry out such observations, when accessible measurements can to guarantee maximum reception of the useful information about unknown properties of object or process. For example, over temperature observations in single(!) point of a specimen, which was heated up to some condition and cooled down on air (the experiment is carried out J.Beck), the given approach can to find: - - Thermal conductivity coefficient of a specimen; - - Heat-transfer coefficient from its lateral surface; - - Non-uniformity of specimen initial state; - - Boundary temperatures time changes; - - And even to establish a measurement position. For other widespread practice case, when the general mathematical model is unknown, offered approach permits to carry out the analysis of object behaviour peculiarities as a whole on observation over its condition in part. For example, the use of offered approach for processing only one phase observation permits to establish dynamics of complex three-phase system (liquid-vapour-superfluid) and to analyze all phase conversions. Such problem arises at research of macro interaction peculiarities of superfluid helium in a channel. Important to note, that the analysis of all processes is received by use only single-phase model. Results of identification have allowed to establish structure of general mathematical model. The similar methods of experimental data interpretation are based in special use of inverse problems. They are constructed on decision of the following questions: 1. Reduction principle for inverse problems solutions; 2. Decomposition principle for inverse problems statement; 3. Conceptual analysis for modeling by inverse problems. The main idea based on association of mathematical modeling under inverse problems with experimental data interpretation. It permits considerably to expand area of application of traditional mathematical models. Thus, offered approach at essential restrictions on direct measurements of object state and its property, permits nevertheless to receive a maximum useful information. The offered approach can actively be used in wide class of problems, switching on, thermophysics, reology, materialogy, chemical kinetic, biochemistry, pharmacology, physics of plasma etc. For everybody who are interested in receiving the answers on these questions please contact with me via e-mail. I should like to send the summary and papers.
