Major construction this article discusses the methodological foundations of intelligent control systems for complex technical objects in the class of hierarchical control systems based on entropy approach. The notion of design space to MIS (management systems dynamically-changing facilities), its topology and metric. The generalized criterion of the complexity of the design decisions. The approaches to the definition of entropy at the executive level, the level of coordination and planning level. The problem of the comparative assessment of the complexity of the control algorithms synthesized based on neural network technology and fuzzy logic. As part of the proposed concept design ISU to the methodological principles of design to the ISU. On the basis of estimates of the complexity of design decisions on the levels of planning, coordination and executive level. This allows a common position to ensure the required quality of design decisions by limiting the complexity of their implementation. Too complex sentence. Split into simpler evaluation of the complexity of the proposed management and algorithmic complexity control algorithms based on entropy approach, which allows on the basis of scalar criterion to evaluate the complexity of integrated design solutions. A method for estimating the complexity of interpolation algorithms based on soft computing technology that allows for a reasonable complexity of algorithms for constructing nonlinear dynamic models, nonlinear regulators.
The research results of the effect of concentration of injected mineral filler on change in adhesion strength of acrylic adhesive composition to the metal substrate are given in the article. The adhesive composition was prepared based on pre-compounded reaction system: the stabilized monomer – methyl methacrylate and polymer modifier – sterol copolymer with methyl methacrylate with followed filling and polymerization in the presence of a redox system.
It is shown that the mobilization to resource preservation of the adhesive contact at the allowable amount of the filler and the thickness of the adhesive layer is due to the overall contribution of the dispersed phase in the change of the structure and macrophysical properties. Experimental data confirm the obtained dependencies: the adhesive strength of the adhesive from the contact area to steel wire; density, glass transition temperature and the calculated value of the Simcha-Boyer constant of block samples from the amount of the filler; character of reducing dynamic shear modulus of the filled composition during heating.
It is suggested that the decrease in density in a volume of polymer phase of filled system provides a slight decrease in adhesion strength of acrylic adhesive to the substrate.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
