Agamalov Yu. R. Features and design opportunities of multifunctional measuring subject to verifiability criterion

Design features of complex multifunctional measuring devices are examined subject to verifiability criterion as a way to simplify the calibration procedure and facilitate its automation. Implementation opportunities are evaluated with a case study of multifunctional immitance meters.

Bobylev D. A. Phase-sensitive transformations invariant to additive noise represented by a finite-degree polynomial

The paper discusses the synthesis of lattice and piecewise constant reference signals for phase-sensitive transformation ensuring its invariance to a disturbance represented by finite-degree polynomial. The analysis of its selective properties is undertaken with the case study of exponential transients and power disturbance rejection in impedance parameter meters. The ways to apply the obtained results for solving wider selective problems are also included.

Yarushkina N. G., Afanasieva T. V. Fuzzy time series as a tool for process dynamics evaluation and measurements

The paper discusses the formulation and the solution scheme of process dynamics interpretation problem where the process states at fixed time points are specified by single parameter’s values forming a time series. An approach to the problem’s solution for various process classes based on fuzzy time series is possible and expedient, and demonstrates structural and functional generality.

Kneller V. Yu. Physical values transformation: specificity, relationships with other processes, and the methods for basic problems solution

Generic knowledge systematization problems for physical quantities transformation (PQT) process are discussed. The transformation process is understood as a process of physical realization of desirable causal relationship between the quantities. Event transformation process is the essence of purposeful action comprising, in particular, PQT, measurement, control, monitoring, and other processes. Based on its analysis, the paper reveals intrinsic relationships of these processes and generic methods for their implementation. At the structural level not related with specific physical nature of the quantities involved, it identifies the methods for solving primary PQT tasks such as establishing the desirable casual relationship between quantities and reducing the effect of undesirable factors on this relationship. The upper levels of deductive classifications of such methods are proposed, and the recommendations for their enhancement are made. The paper’s important feature is an attempt of deductive, logically transparent inference and systematization of knowledge under consideration based on the knowledge from higher levels of consideration.
