Vacuum Brazing of Dissimilar Joints Mo-SS with Cu-Mn-Ni Brazing Filler Metal

The complexity of joining dissimilar materials, such as molybdenum-stainless steel, is due to the difference in thermal coefficients of linear expansion and low oxidation resistance of molybdenum. In this connection, brazing of this pair of materials should be performed in vacuum. The selection of chemical composition of brazing filler metal and its melting temperature range is very important. This work presents the results of metallographic and micro X-Ray spectral analysis investigations of dissimilar brazed joints of molybdenum-stainless steel and shows the features of the formation of brazed seams at application of brazing filler metals of Cu-Mn-Ni(Me) system. It is found that at brazed seam, crystallize reaction layers form the side of molybdenum. One layer is based on molybdenum, enriched in iron and silicon. The second layer is based on iron, enriched in silicon. At brazing temperature of 1100°C, base metal dispersion occurs, which can be avoided at temperature lowering to 1084°C. The structure of solid solution with a small amount of iron-enriched dispersed phase crystallizes in the central zone of brazed seams. The brazed joints produced with application of brazing filler metal based on Cu-Mn-Ni system are characterized by maximum values of shear strength

Psychological Strategies for Overcoming the Life Crisis of the Individual in Postmodern Practical Psychology

The article talks about the personality-oriented approach of postmodern practical psychology to counseling a crisis client. Coping strategies for overcoming a life crisis by a person at the cognitive, emotional and behavioral levels are analyzed. Based on the consideration of practical work with crisis clients, algorithms for overcoming a crisis situation in the form of stages and phases of its experience are highlighted. The important role of neuropsychological correction at the first stage of work with the client is emphasized. Theoretical and methodological provisions of postmodern psychotherapy and practical psychology on the features of psychological support of a crisis client, taking into account his personal resource. The variability of the personality as one of its fundamental properties and the psychological mechanism providing a flexible choice of coping strategies, process of adaptation to conditions of crisis situation are considered. It is revealed that in the conditions of overcoming the life crisis there are personal transformations as expression and development of specific personal characteristics and properties. The model of overcoming a life crisis situation by an individual in the context of postmodern practical psychology is presented. In the presented author’s model of overcoming the personal crisis the postmodernist, personality-oriented and phenomenological approaches are applied.</p

Розробка архітектурно-логічної моделі автоматизації управління процесом створення складних кіберфізіческіх виробничих систем

Modern highly technological production puts forward new requirements and approaches to the implementation of the Industry 4.0 concept. To achieve this, it is necessary to develop a cyber-physical production system that would make it possible to fully take into consideration all the factors of the actual production system. All solutions must pursue the global goal of making the best use of production time and resources, as well as meet the "Lean Production" concept. Existing ISO-95, 5C, and 8C cyber-physical production systems (CPPS) reference architectures cannot provide clearly expressed systematization and detailing. Such systems are a set of general recommendations that show the interaction processes among the physical and cyber-components of CPPS. This paper reports a new approach to the systemic representation of the processes for managing the development of complex cyber-physical production systems in the face of today's threats. We have suggested a systemic representation of automating the process of managing the development of complex CPPS. Modern threats to the cyber-physical and information and communication systems (ICS) have been considered, which underlie CPPS. An architectural-logical model, as well as methods for automating the CPPS development process management, have been developed. This could help build a logical relationship from the initial "target" stage to the process of obtaining "management algorithms" at each level and stage of CPPS development as a symbiosis of physical and cyber-components. The devised CPPS development process management model provides an opportunity to propose a group of mathematical models and methods that logically link all development stages into a single "rigid" hierarchical sequence. This makes it possible to build a single information space with a set of complex CPPS development methodology. The proposed solutions could enable the development of an automated system to manage the process of the development of complex CPPSСовременное высокотехнологичное производство выдвигает новые требования и подходы к реализации концепции Industry 4.0. Для достижения этого необходимо разработать киберфизическую производственную систему, которая позволит полностью учитывать все факторы реальной производственной системы. Все решения должны преследовать глобальную цель достижения оптимальности использования времени и ресурсов производства, а также удовлетворять концепции «Lean Production». Существующие эталонные архитектуры ISO-95, 5С и 8С процессов управления разработкой киберфизических производственных систем (CPPS) не имеют четко выраженную систематизацию и детализацию. Такие системы представляют собой набор общих рекомендаций, в которых показаны процессы взаимодействия между физическими и киберсоставляющими CPPS. В статье представлен новый подход к системному представлению процессов управления разработки сложных киберфизических производственных систем в условиях современных угроз. Предложено системное представление автоматизации процесса управления разработкой сложных CPPS. Рассмотрены современные угрозы на киберфизические и информационно-коммуникационные системы (ICS), которые составляют основу CPPS. Разработано архитектурно-логическую модель и методы автоматизации процесса управления разработки CPPS. Это позволит построить логическую взаимосвязь от начального «целевого» этапа до процесса получения «алгоритмов управления» на каждом уровне и этапе разработки CPPS как симбиоз физического и киберсоставляющих. Разработанная модель процесса управления разработкой CPPS дает возможность предложить группу математических моделей и методов, которые логически связывают все этапы разработки в единую «жесткую» иерархическую последовательность. Это дает возможность построить единое информационное пространство с набором методологии разработки сложных CPPS. Предложенные решения позволят разработать автоматизированную систему процесса управления разработкой сложных CPPSСучасне високотехнологічне виробництво висуває нові вимоги і підходи до реалізації концепції Industry 4.0.

Mobile Robot Position Determining Using Odometry Method

&lt;p&gt;In this article, the authors propose an analysis of the cumulative error of robot movement. We are considering a two-wheeled robot based on an Arduino board with three ultrasonic rangefinders. The position of the mobile robot is calculated using the odometry method. Experiments were carried out on various coatings. And the calculated position of the robot was compared with the real one. When writing a mobile robot control program, it is proposed to take these results into account.&lt;/p&gt
