Abstract:
The structural-parametric synthesis of neural networks of deep learning, in particular convolutional neural networks used in image processing, is considered. The classification of modern architectures of convolutional neural networks is given. It is shown that almost every convolutional neural network, depending on its topology, has unique blocks that determine its essential features (for example, Squeeze and Excitation Block, Convolutional Block of Attention Module (Channel attention module, Spatial attention module), Residual block, Inception module, ResNeXt block. It is stated the problem of structural-parametric synthesis of convolutional neural networks, for the solution of which it is proposed to use a genetic algorithm. The genetic algorithm is used to effectively overcome a large search space: on the one hand, to generate possible topologies of the convolutional neural network, namely the choice of specific blocks and their locations in the structure of the convolutional neural network, and on the other hand to solve the problem of structural-parametric synthesis of convolutional neural network of selected topology. The most significant parameters of the convolutional neural network are determined. An encoding method is proposed that allows to repre- sent each network structure in the form of a string of fixed length in binary format. After that, several standard genetic operations were identified, i.e. selection, mutation and crossover, which eliminate weak individuals of the previous generation and use them to generate competitive ones. An example of solving this problem is given, a database (ultrasound results) of patients with thyroid disease was used as a training sample.

Abstract:
The morphological methods are successful analytical and practical tools for development and choice of new engineering solutions. They can be successfully used in the conceptual and preliminary design stages of the development of new systems, products and technologies. The article discusses the scope of application, classification, advantages and disadvantages of this approach. The design process consists of two stages - structural synthesis and parametric optimization. The morphological approach is used for the structural synthesis stage. Structural synthesis generates a significant number of variants. This stage is the most important tool for achieving the high characteristics of the systems being designed. The article discusses the ratios between parametric, structural and structural-parametric methods of synthesis. The possibility of computerizing the stage of structural synthesis on morphological approach is discussed.

Abstract:
Дисертація присвячена вирішенню важливої науково-практичної проблеми – розробці методології синтезу мобільних роботів довільної орієнтації (РДО) у технологічному просторі з системами втримання мобільних роботів на поверхні переміщення для компенсації гравітаційного та технологічного навантаження. Запропонована методологія автоматизованого синтезу мобільних роботів довільної орієнтації у технологічному просторі базується на трьох основоположних принципах: 1) нагромадження потенціальної енергії переміщення й перетворення її в кінетичну енергію руху робота; 2) інтеграції приводів поздовжнього й вертикального переміщення; 3) застосування аеродинамічної піднімальної сили як засобу протидії гравітаційному навантаженню на робот. На основі розробленої методології автоматизованого керування синтезом мобільних роботів створені нові модифікації мобільних засобів в галузі робототехніки. Проведені експериментальні дослідження керування технологічними режимами аеродинамічної піднімальної сили як засобу протидії гравітаційному навантаженню, підтверджують доцільність технічних розв'язок мобільних РДО з метою збільшення їх технологічного навантаження.
The dissertation is devoted to solving an important scientific and practical problem – the development of a methodology for controlling the synthesis process of mobile robots of arbitrary orientation in the technological space with systems for holding mobile robots on the surface of moving to compensate for the gravitational load. The soluti on to this problem is aimed at creating a new means of production – a variety of robotics in the form of mobile robots of arbitrary orientation, which takes into account the needs of society, the level of its socio-economic, scientific and technological development in modern production. Studies are devoted to solving the problem of excluding human labor from the sphere of servicing high-rise facilities at industrial and municipal facilities and providing a person with remote automatic control functions. Mobile robots of arbitrary orientation in the technological space, also known as robots with vertical movement, and in international publications under the name Climber Robot are a new modification of mobile robots equipped with tools to hold the robot on a surface of arbitrary orientation relative to the horizon of the technological space. The creation of this type of robotics is at the initial stage and is dictated by the need for technological operations in such areas as monitoring of industrial facilities, installation anddismantling of building structures, repair and preventive maintenance of their components, maintenance of high-rise buildings of public utilities, forest and parklands, etc. n. The problem of using mobile robots is especially relevant in the extreme conditions oftechnological disasters in which human work is dangerous and even unacceptable to humans. The methodology for managing the synthesis of mobile robots in the technological space is based on three fundamental principles: 1) the accumulation of potential displacement energy and its conversion into kinetic energy of robot movement; 2) integration of drives of longitudinal and vertical movement, as well as drives of changing the orientation of the robot along a given route; 3) the use of aerodynamic lifting force as a means of counteracting the gravitational load in order to increase the technological load while reducing the power of the drive drives and the adhesion of the robot to the displacement surface. The indicated directions in world theory and practice of the experimental construction of mobile robots have not yet been investigated. Based on the developed methodology for managing the synthesis of mobile robots, new modifications of mobile robots have been created. The proposed technical solutions allow robots to move along surfaces of arbitrary orientation in various coordinate systems with an arbitrary topology of the surfaces of movement of the robot. The experimental studies of the control of aerodynamic lift regimes as a means of counteracting the gravitational load confirm the feasibility of using the developed technical solutions ofmobile robots. As a result of setting up a full factorial experiment, a regression and analytical model of the relationship between the values of the aerodynamic lift and the operating modes of the jet thrust generator, namely, the number and diameter of nozzles, as well asthe pressure of the compressed air outflow from the generator nozzles, was obtained. The indicated dependences make it possible to determine the quasi -optimal values of thecontrol modes of the aerodynamic thrust generator. Also, dynamic modeling of themovement of mobile robots on surfaces of arbitrary orientation and different topology has been carried out. The obtained analytical dependences make it possible to calculate the ultimate technological load of the robot and the allowable weight of the robot. Thesedependencies formed the basis for the developed engineering techniques for designing functional devices and drives of mobile robots. These engineering methods for calculating the parameters of mobile robots are automated based on CAE technologies for computeraided design systems. Special programs have been created that allow one to calculate the quasi-optimal values of the modes of operation of mobile robots of arbitrary orientation in the technological space. As a result of theoretical and experimental studies, a synthesis of fundamentally new designs of mobile robots for the maintenance of high-rise industrial and agricultural facilities was carried out. New models of mobile robots allow performing not only monitoring operations of the specified objects, but also power technological operations. Such mobile robots make it possible to exclude the presence of a person in hazardous areas for performing various production operations and to hand over to the operator only the functions of controlling the robots, which is especially important for the conditions of man-made disasters. The implementation of these modifications helps to reduce the total power of the drives and increase the reliability of the retention of robots on a surfa ce of arbitrary orientation in the technological space.

Abstract:
This paper presents a new approach to synthesize the control for one class of uncertain Metzler-Takagi-Sugeno time-delay systems. The structural parametric constraints of the closed-loop system, their diagonal matrix representations as well as the interval system parameter bounds are accounted into an associated set of the linear matrix inequalities. After sorting out the relevant preliminaries in the uncertain structure of the Metzler systems and the specific properties of the time-delay positive system representations, the design conditions reflecting quadratic system stability of the considered system class are proven in the matrix inequality framework. The main result of the control law parameter design is shown in detail by the numerical example in order to characterize potential adaptation of the method for purely Metzler matrix parameter structures.

Abstract:
Given the complex nature of consciousness, many agree that in order to study it properly we need a non-reductive, pluralistic and synthetic (i.e. systemic) approach. Despite the relative popularity of the systems methodology in the vast field of the study of consciousness, system approach (i.e., modeling something as a system) is very well used for a reductive purposes, and there is no consensus on the issue of a clear understanding of the non-reductive use of one or another system approach in area. Hence, the purpose of my research is methodological reflection on the problem of the adequacy of the system approach for the non-reductive deliberation on the problem of consciousness. I formulate criteria of adequacy in a form of three principles that should be followed in any non-reductive (not just systemic) study of consciousness. The principle of structural-ontological (or metaphysical) neutrality is the first one. This principle suspends all metaphysical solutions to the problem of consciousness and plays the role of a necessary precondition. Many pointless disputes in the field could be avoided if the disputing parties adhered to this principle. The second principle of differentiation of ontic modes of experience and epistemic perspectives retains the multifaceted complex structure of consciousness after it is stripped of its metaphysical baggage. The principle of embodiment adds some feedback dynamics to the story. At the next step I implement the principles of adequacy in a particular case of the General parametric systems theory, developed by a philosopher and logician Avenir Uyemov. The conceptual foundations of this theory in relation to its compliance with the criteria of adequacy are revealed. It turns out that two of three principles exist at the meta-language of the theory. The principle of neutrality follows by definition of the General system theory – i.e., theory applicable to all kinds of systems. And the principle of embodiment exists as a feedback of the substrate to the structure of a system. The principle of differentiation in this case is the most crucial. If this theory is not enriched at the level of object-language with epistemic perspectives and ontic modes of experience, then we won’t get a no-reductive explication of consciousness, even if it remains systemic by definition. In the end I give a systemic definition of consciousness through its basic feature which is (I conjecture) modeling of reality or different kinds of experience through epistemic perspectives, where complex structural ontology of consciousness ‘in-forms’ or structures its epistemology, which in turn models it in accordance with the needs of a conscious system.

Abstract The ideas and methods behind a new system, ODESSY, for optimum mechanical engineering design are described. The motivation behind this work is found in the current trend toward unification of engineering design tools which were previously developed and used separately, namely geometric modeling in the form of CAD systems, and mechanical analysis in the form of finite element programs. The united capabilities of these techniques allow for a major step forward in Mechanical Engineering Design, i.e. from tools aimed at analysis to tools aimed directly at synthesis.

Abstract:
Design productivity plays a crucial role in the development of large-scale mechanical systems because of the involvement of a great amount of resources, long life cycle, and multi-disciplinary teams. At the early stage parametric design, the generation and evaluation of robust design alternatives are expected at the least expense. In this paper, a direct synthesis (DS) method is presented. With simultaneous consideration of negotiability, bi-directional robustness, and efficiency in a “Zoom-in” process, the DS can facilitate the quick synthesis of robust design alternatives without resorting to numerous iterations. The preliminary industrial application results of the Direct Synthesis method show its effectiveness for robustness enhancement and cost reduction at the early stage parametric design of a vehicle structural system.
