Pereidenko A. Computerized diagnostic system of products from composite materials.

The object of research: the process of diagnosing the state of products from composite materials. The purpose of research: develop a computerized system for diagnosis of composite materials with improved efficiency. Methods of research: methods of nondestructive testing and technical diagnostics; methods of probability theory, mathematical statistics and stochastic processes; methods of pattern recognition; methods of mathematical and computer modeling; methods of designing neural networks. Theoretical and practical results and innovations: mathematical models of information signals based on orthogonal basis functions of the discrete Hartley transform were developed and investigated for building a library of information signals and using it in computerized diagnostic system training and setup; improved a method of developing neural network classifiers for the analysis of experimental data in the diagnosis of products from composite materials, which improves the reliability of the control of products from composite materials; further developing of diagnostic decision making method for solving problems of composite materials diagnostic; determined the optimal architecture of neural networks for a classifier built-in computerized diagnostic system of products from composite materials; improvements to existing architecture of ART-2, Fuzzy-ART, Kohonen and multilayer perceptron neural networks, developed special networks for diagnostic composite materials; a developed computerized system can be used for diagnostic and monitoring the products from composite materials. A subject degree of introduction: Effectiveness of implantation: are used in the State Enterprise of the Ministry of Defense of Ukraine "Lutsk Repair Plant" Motor ", Ukrainian Research Institute for Analytical Instrumentation" UKRANALIT "and at the department of information-measuring systems of the National Aviation University. Sphere of use: diagnostic systems for nondestructive testing of products from composite materials and state recognition of products in aviation and other industries.
