In this paper, an approach to expert rules refinement within the framework of fuzzy relational calculus is proposed. The system of fuzzy rules can be rearranged as a collection of linguistic solutions of fuzzy relational equations using the composite system of fuzzy terms. Resolution of fuzzy relational equations guarantees the optimal number of fuzzy rules for each output fuzzy term and the optimal geometry of input fuzzy terms for each linguistic solution. © 2013 IEEE.

The opportunity of direct transformation of pressure in frequency is shown on the basis of the hybrid integrated circuit consisting of the two-collector tenzosensitive transistor and the field two-gate transistor with an active inductive element on the basis of the bipolar transistor with a phase-shifting RC chain. Analytical dependencies of transformation function and the equation of sensitivity are received. Theoretical and experimental researches have shown, that sensitivity of the transducer makes 1,55-1,10 kHz /kPa. © 2015 IEEE.

In this paper, a problem of MIMO object identification expressed mathematically in terms of fuzzy relational equations is considered. The identification problem consists of extraction of an unknown relational matrix, and also parameters of membership functions included in fuzzy knowledge base, which can be translated as a set of fuzzy IF-THEN rules. In fuzzy relational calculus this type of the problem relates to inverse problem and requires resolution for the composite fuzzy relational equations. The search for solution amounts to solving an optimization problem using a genetic algorithm. The resulting solution is linguistically interpreted as a set of possible rules bases. The approach proposed is illustrated by computer experiment and examples of diagnosis and prediction. © 2012 Springer-Verlag Berlin Heidelberg.

This article discusses a new approach to the optimization of agricultural enterprises on complex processing of raw materials on the basis of the methodology of the optimal aggregation, which allows you to replace the multidimensional problems of nonlinear programming system of one-dimensional problems. The process of solving the problem: the mapping of the resource structure of the enterprise in a binary tree of optimal aggregation and development of the binary operator optimal aggregation. An example is given for a typical dairy. © 2015 Lviv Polytechnic National University.

The noise immunity of immitance logic elements (ILEs) realized on the basis of a transistor generalized immitance converter (GIC) is analytically estimated. It is shown that this estimate is determined by the effect of static interferences (temperature and supply voltage changes), high-frequency interferences (reference oscillation power and frequency changes), and immitance interferences (changes of the real and imaginary components of the immitance to be converted and changes of internal interferences related with the GIC potential instability). It is suggested to use the relative noise immunity coefficients for the immitance levels of logic 0-γ C, and logic 1-γ L, for analytical estimation of the ILE noise immunity. The admissible range of variation of these immitance levels are 0 < γ C < 1 and 0 < γ L < 1. The noise immunity is quantitatively estimated. As a result, it is found that, within the reference frequency 0.4-1.5 GHz, an ILE's reserve of the noise immunity to the instability of the imaginary component of the high-Q input immitance exceeds 80% and that the noise immunity reserve is reduced by no more than 5% when the supply voltage changes by 30% and when the temperature changes by 40%. © 2013 Pleiades Publishing, Inc.
