FUNCTIONAL-STRUCTURAL SYNTHESIS OF A SYSTEM FOR COLLECTION AND PROCESSING OF INFORMATION ON SPACE VEHICLES TECHNICAL CONDITION Shestopalova O. L.
On the example of synthesis of structure of two-level distributed system of collection and pro-cessing of information on technical condition of space vehicles in the course of their life cycle, a state-ment is given of the problem of formation of the information system target state.

Composition and dimensions of generalized vectors of structural parameters of the system and its elements are specified. Expressions for estimating the prob-lem dimensionality are presented.

ESTIMATION OF THE PREVALENCE OF TYPES OF DISTRIBUTION LAWS BASED ON THE ENTROPY COEFFICIENT VALUE Lazarev V. L.
Results of studies of the "prevalence" of distribution laws in practice are presented. The basis of the studies is the entropy coefficient for parameters of various objects and processes. Inconsistency of the approach based on "total" approximation of the real distribution laws by the normal law when con-ducting research and organizing the management of objects of different nature is substantiated. It is ar-gued that accounting for variability of the analyzed parameter in the form of the entropy coefficient of a real distribution law increases the adequacy of descriptions of uncertainty states, which, in turn, affects the effectiveness of research and decision-making. It makes the methods and technologies of the theory of entropy potentials very convenient and useful "tools" for solving such problems in question. The theory potentialities allow monitoring and organization of control of uncertainty states of complex systems. The use of obtained results makes it possible to quickly assess the dominance of specific types of distribution laws in different situations when solving monitoring and control problems using the entropy approach.

ПРИМЕНЕНИЕ МАШИННОГО ЗРЕНИЯ В ЗАДАЧАХ АВТОМАТИЧЕСКОГО ПОЗИЦИОНИРОВАНИЯ ИНСТРУМЕНТА МОДУЛЬНОГО ОБОРУДОВАНИЯ
Модульное оборудование отличается универсальностью и может выполнять производственные операции разных типов, как обрабатывающие, так и вспомогательные.

Предложена методика автоматизированного позиционирования съемных модулей для трехкоординатной платформы, основанная на применении системы технического зрения. Разработан алгоритм, совмещающий обзорную камеру, располагаемую над рабочим полем, с инкрементальными энкодерами сервоприводов установки. Для определения конфигурации рабочего пространства и размеров модуля применяется библиотека оптических меток. Данная методика позволяет избежать ошибки установки модулей вручную, сопоставив координатные системы модуля и платформы, а также повысить уровень автоматизации рабочего процесса производства изделия.

DYNAMIC CHARACTERISTICS OF PIEZOELECTRIC HARVESTERS Yuriy V. Zagashvili, Vitaly G. Rudenko
Dynamic models of piezo energy harvesters (PEH) based on thin single-layer piezoelectric elements (PE) are considered. Using an equivalent circuitry of the piezoelectric harvester, differential equations are obtained and the transfer functions of the PEH, which relate the input variable (the load force on the PE) to the output variables (the voltage and current of the load capacitor), are found. Analytical studies of steady-state and transient processes in PEH under typical loading forces (pulsed, stepped, harmonic) are carried out. It is shown that a sufficient condition for stable piezoelectric energy harvesting, which consists in a continuous charge of the load capacitor, is a non-zero acceleration of the load force on the PE. The influence of the parameters PEH – equivalent values of resistance, capacitance and inductance of PE, resistance of conductors and diodes of the rectifier, capacitance of the load capacitor, load resistance – on transient processes is considered. The estimate of the maximum achievable PEH power at a monoharmonic load force on the PE is obtained. The data of analytical calculations and experimental studies of the piezoelectric energy harvesting in PG with a single-layer disk PE in the load force jump and meander modes are presented. The results of the research are intended for the design of PEH with a known range of loading forces.

The paper considers a new pausing method for intonational speech synthesis systems based on the analysis of distributional semantics in large text corpora. The support vector machine and two speech corpora in Kazakh were used for pause prediction. The prediction of pause places was carried out at the level of bigrams, where the input parameters of the bigram were the vector representations of both of its words and their bit string representation in the Brown cluster model. The carried out studies have shown that the proposed pausing method for the automatic speech synthesis systems for the Kazakh language in the narrative style provides high accuracy of pause placement. The importance of homogeneous data usage was confirmed experimentally for solving such problems. Such approach can facilitate the creation of automatic speech synthesis for many languages.
