NEURAL NETWORK INFORMATION-MEASURING SYSTEM IN TASKS OF RESOURCE PREDICTION

It was established that methods based on artificial neural networks (HC) find the most widespread in predicting thermal processes in power cable networks. Analysis of influence of various functions of HC activation on forecast error of thermoflux processes in power cable networks was carried out. It is established that the minimum error of thermal processes prediction in power cable networks is HC with function of logsig activation in hidden layer and pureline in output layer.

Design of an information-measuring system for monitoring deformation and displacement of rock massif layers based on fiber-optic sensors

This paper reports a study into designing an information-measuring system that could be used in coal mines that are dangerous in terms of the explosion of coal dust and methane gas. The results of reviewing technical advancements in the field of fiber-optic system development are given. To solve the set task, prototypes of a fiber-optic sensor of a new type and a hardware-software complex were constructed. The research aims to improve the safety of workers at coal enterprises. The result of the theoretical research has established that additional losses related to a micro bending should be taken into consideration while accounting for the effect of photoelasticity. The fundamental difference between the idea reported here and existing analogs is the development of a hardware-software complex capable of working with a single-mode optical fiber of great length with a significant noise level. The data processing unit is equipped with a television matrix and can analyze changes in the pixels of a light spot. The proposed system is quasi-distributed; it controls individual points within a rock massif. The designed hardware-software system provides high noise immunity of measuring channels when the external temperature changes. The research results helped develop an information-measuring system for monitoring the deformation and displacement of rock massif layers based on fiber-optic sensors, capable of operating in an explosive environment. The system makes it possible to control several layers located in the roof of the workings, while the fiber-optic sensor may contain two or three sensitive elements that are connected to different channels. With a sharp fluctuation in pressure and an increase in the displacement parameter, the system triggers a warning signal about the danger.

Methodology and information-measuring system for personalized synthesis of lower limb prostheses

Introduction: One of the methods for managing the quality of prosthetics is optimizing the composition of a modular prosthesis components. Mistakes in choosing models for functional modules of a prosthesis lead to a limited realization of the patient's potential capabilities, or to the choice of expensive highly functional models whose potential cannot be fully realized with the given body system disabilities. One of the most effective ways to solve this problem is to use the computer technology capabilities. Purpose: Substantiation of the methodology for the development of an innovative computer technology for personalized synthesis of a lower-limb prosthesis, including the development of the structure of an information-measuring system for its implementation. Methods: Analysis, synthesis, analogy; expert survey; analytic hierarchy process (Saaty method). The conceptual language of the International Classification of Functioning, Disability and Health was used to describe the factors influencing the requirements for the characteristics of prosthetic modules. Results: In order to choose models for prosthetic modules, we should use an extended system of factors, including both the basic factors associated with the purpose of the products and indicated in the catalogs, and additional factors: impairment indicators of the body functions and structures, the capacity and performance of the patient's activity and participation, the presence of barriers and facilitators environmental factors in which the prosthesis is planned to be used. Taking this system of factors into account, a structural diagram of an information-measuring system for examining a prosthetic patient has been developed. To select the components for the prosthesis, we have substantiated the necessity of creating a global electronic catalog, combining structured information on the models of prosthetic modules supplied by various manufacturers. A matrix representation form is proposed for the knowledge base, reflecting the rules for choosing models according to the correspondence of their characteristics to the estimates of the factors. The methodology of computerized selection of models from the electronic catalog has been substantiated. Practical relevance: The results of the work are a step towards the creation of a technology for a computerized multicriteria choice of components for a modular prosthesis, taking into account the personal needs and functional capabilities of the patient. The use of this technology will improve the patient's rehabilitation level and the quality of his or her life.

ALGORITHM FOR MANAGING THE STRUCTURE OF AN INFORMATION-MEASURING SYSTEM SUBJECT TO ORGANIZED INTERFERENCE

Эффективность информационно-измерительных систем, применяемых в таких областях как радиолокация, связь, во многом зависит от их устойчивости к действию преднамеренно создаваемых помех. В статье рассматривается подход к повышению помехоустойчивости информационно-измерительных систем путем адаптации их структуры к изменениям сигнально-помеховой обстановки. Методами теории оптимизации динамических систем случайной структуры синтезирован алгоритм управления структурой информационно-измерительной системы, в состав которой входит радиолокационная станция. Показаны структурные схемы вновь разрабатываемых устройств. Приведены результаты исследования разработанного алгоритма управления структурой информационно-измерительной системы, подверженной действию организованных помех, подтверждающие его практическую значимость. Результаты исследований могут быть использованы при разработке информационно-измерительных и управляющих систем в области управления воздушным движением, самонаведения подвижных объектов, в связных и навигационных системах, других системах, располагающих открытыми входными информационными каналами. The effectiveness of information and measurement systems used in such areas as radar, communications, largely depends on their resistance to the action of deliberately generated interference. The article discusses an approach to increasing the noise immunity of information-measuring systems by adapting their structure to changes in the signal-interference environment. Using the methods of the theory of optimization of dynamic systems of random structure, an algorithm for controlling the structure of an information-measuring system, which includes a radar station, has been synthesized. The block diagrams of newly developed devices are shown. The results of the study of the developed algorithm for controlling the structure of the information-measuring system exposed to organized interference are presented, confirming its practical significance. The research results can be used in the development of information-measuring and control systems in the field of air traffic control, homing of mobile objects, in communication and navigation systems, and other systems with open input information channels.

Research of the Piezo Actuator Information-Measuring System for Studying the Strength Characteristics of Filling Materials

В статье рассмотрена пьезоактюаторная информационно-измерительная система с телекоммуникационной сетью для изучения композитных пломбировочных материалов, реализующая тензометрический, акустический, оптический и электрометрический способы контроля образцов. Изложена возможность анализа прочностных характеристик образца по его диаграммам сжатия в статическом режиме и при циклических нагрузках с заданными частотой колебаний и законом воздействия в цифровом виде. Получены рекомендации, что для изучения твердых тканей зубов лучше применять последовательное расположение двух пьезоактюаторов, а не параллельное. Это связано с тем, что твердые ткани зубов имеют относительно малый модуль Юнга (в частности, у дентина 14,7 МПа). При этом максимальная генерируемая сила от двух последовательных пьезоактюаторов будет больше, чем от параллельных. Разработана электромеханическая модель процесса нагружения образца в силовой пьезоактюаторной установке, исследованы вопросы повышения точности измерения прочностных характеристик с применением пакета Micro-Сap. Создана трехмерная модель напряженно-деформируемого состояния образца в программе Ansys Mechanical, дающая возможность проводить теоретические исследования надежности соединения пломбировочных материалов с твердыми тканями зуба. Разработана методика сравнительной оценки погрешностей моделирования работы силовой установки в пакете Micro-Cap с результатами, полученными в программе Ansys Mechanical (принятыми в качестве эталона). Для реализации методики оценки в приведенных моделях одновременно менялся модуль Юнга образца от 10 до 330 ГПа.
