Constitutional law: the field of law or a specific basic subsystem being a skeleton of national system of law

The article critically analyzes an approach to the interpretation of Constitutional Law as the field of national law and a subsystem of public law still popular in post-Soviet and national Constitutional scholarship.The author provides arguments on methodological inadequacy of traditional post-Soviet legal criteria of the division of law into branches and institutes. The availability of the subject of legal regulation (homogenic societal relations regulated by a number of legal norms) and the method of legal regulation being an instrument of the influence on societal relations being regulated by those, in each branch of law. It highly exceeds the borders of legal regulation of state governance homogenic relations being the subject of Constitutional law in the past. The scope of methods applied by it is much wider than the traditional public law imperative method built on the relations of power subordination. Therefore, in addition to the abovementioned method, Constitutional law frequently applies the dispositive method based on the equality of relations between the coordinated subjects on the contrary to subordination. Moreover, Constitutional law does not limit itself to the scope of national, internal law of the country. Its certain provisions have a supranational status bearing the ties of Constitutional law with International law.The article concludes that basing on its ontological nature, Constitutional law occupies a wider scope than it has traditionally been viewed and differentiated. It establishes basic, starting principles for the functioning and development of all the most important areas of societal relations linked primarily to the basics of legal status of the individual and the role of the state in its assurance. Constitutional law makes a specific basic subsystem of the national legal system and provides a fundamental basis for all of its branches as well as acts as a system-building pivot for the whole national legal system.Article received 13.03.2019

Spectral characteristics of a modified inverted-Y system beyond rotating wave approximation

The spectral properties of a multilevel atomic system interacting with multiple electromagnetic fields, a modified inverted-Y system, have been theoretically investigated. In this study, a numerical matrix propagation method has been employed to study the spectral characteristics beyond the validity regime of the rotating wave approximations. The studied atomic system, comprising of several basic sub-systems, i.e. lambda, ladder, vee, N and inverted-Y, is useful to study the interdependence among these basic sub-systems. The key features of the obtained probe spectra as a function of coupling strength and detuning of the associated electromagnetic fields show inter-conversion, splitting and shifting of the transparency and absorption peaks. The dressed and doubly dressed state formalism have been utilized to explain the numerically obtained results. This study has application in design of novel optical devices capable of multi-channel optical communication along with switching.

Introduction. The steady increase in scientific information, the growth of the social role of the individual and the intellectualization of his work, the rapid change in military technology and technology require constant development, modernization of military education, bringing its condition and capabilities into line with the socio-economic needs of the developing society. This, first of all, concerns the provision of a qualitatively new level of educational process in military education institutions, which is carried out in the corresponding pedagogical systems of the basic functional subsystems of any system of education. An important component of such systems is the computer-based learning environment and electronic media that it forms, as well as information technology education, which reflect and provide the introduction of modern teaching methods in educational practice.Purpose. The purpose of the paper is to answer some of the important theoretical and practical questions of their solution, namely: 1. What do we mean by electronic means and their collections, what is their place and what role they play in the modern educational process? 2. In what educational and educational environment electronic means are used, what we mean by computer-oriented learning environment, how these categories are interrelated and what role in them is determined by electronic means.Methods. The research was conducted using the following theoretical methods: analysis and synthesis, generalization and systematization; modeling.Results. The results of the study indicate that the skillful use of modern electronic means and information technology training in the educational process of educational institutions of military education creates a multifunctional computer-oriented learning environment. The only educational space provides the normalization and standardization of the creation of information educational resources, the expansion of scale and unification of their application in educational practice.Originality. From the point of view of the system approach (task), a multidimensional problem such as the creation of electronic facilities and a computer-based learning environment of modern pedagogical systems and scientific and practical approaches to their creation and development at the stage of modernization of Ukraine's military education are considered.Conclusion. Within the framework of this article, we have tried in a variety of ways and, in many ways, from our own point of view to consider this multidimensional problem, to indicate the level of our understanding. At the same time, a wide range of issues related to this problem would not allow to comprehensively highlight such an issue of today for the military education of Ukraine and the complex problem as the creation of electronic means and a computer-based learning environment of modern pedagogical systems, scientific and practical approaches to their creation and development at the stage of modernization of Ukrainian military education. The prospect of further development of this problem is the question of the formation of the composition and structure of the computer-based learning environment both on the level of scientific research, and on the level of practical implementation.

Justification of the basic algorithms of the mine safety information system

This article is devoted to substantiation of basic algorithms for the information system which could provide prompt making of decisions on ensuring safety of underground mining jobs, which are of great importance for the job safety at the mining enterprises. The information safety system architecture and some basic algorithms was developed. The system differs by its methods for prompt predicting and assessing of different scenarios of geomechanical process development, and which includes the following subsystems: a basic client-server subsystem with functions of interaction between the personnel and management of the enterprise; a reference and information subsystem, which supports a decision making process, accumulates data and analyzes technical documentation; a subsystem for analyzing the job safety by geomechanical factors and for assessing of the “support-rocks” system state basing on the risk criteria and mathematical fuzzy logics. Two integral indicators of safety are formed. The first indicator is used to control entering of the control object to the emergency mode and to determine a factor, which requires urgent interruption, and the second indicator is used for the total assessment of the object current state.

Technological Factors and Management Transformation in Social and Economic Systems

Today, a rapid, interconnected change in a large number of factors that have a significant impact on development of enterprises makes uncertainty an ongoing reality of management. As a key driver of change, new technologies enter new areas of life; global market, common information space, and reduction in product life cycles enhance competition and demand new higher standards from enterprises and their staffs. Development of management theory and practice does not meet the requirements set by the business environment. Transformation of management and its basic subsystems becomes a recognized need. Effective management in contemporary business landscape involves a combination of flexibility and adaptability, which does not exclude a certain level of stability as a pre-requisite to obtain competencies. Therefore, from a strategic point of view, the main task of modern management is to find a balance of stability and flexibility, that will make an effective management real. What needs to be done is shown in studies in a consistent manner. At the same time, to do that is mostly described in general words. The author believe that one must answer the question first: an understanding why we should change, i. e. what factors affect transforming management of economic and social systems, and how they do that is an initial stage of successful adaptation the existing management concepts and practices. The article describes the characteristics of impact of technological factors on the management, which makes the change processes controllable and improves the management effectiveness.

Adults’ sensitivity to graphotactic differences within the English vocabulary

AbstractLinguists have described the English vocabulary as including Latinate and basic subsystems. In three experiments with a total of 93 participants, we asked whether skilled readers are sensitive to graphotactic differences between these systems. Participants saw pairs of nonwords and were asked to choose the item in each pair that appeared more wordlike. Participants were more likely to select an item with an onset and an ending that suggested the same system than an item with a mismatch. Participants also used the presence of a single versus double medial consonant as a marker of the system to which an item belongs. The results suggest that skilled readers have learned about some of the graphotactic differences between Latinate and basic words and do not treat English as a monolithic system.

Data Normalization and Database Design for Joglosemar Tourism

As the observation result, tourism destination represents a complex social system, called a tourist destination system, consisting of four basic subsystems: tourists, providers or managers of tourism, communities, and other organizations or institutions. Tourism development of a region is based on the design, promotion and publication to a number of potential travelers as well as providing the services needed for tourists to access and live in the tourist destination. The advantages of tourist destinations are usually based on the resources available in their place. To support the publication of tourist destinations, it takes information system services that are easy to use and seen by potential tourists, which are publication of tourism destination and its itinerary integrated through web applications and Google Maps. This research produce a data model design as a support for implementation of information system. This data model has been normalized so that data becomes independent and data duplication does not occur so that it can be used together on other systems.

Trajectory Optimization of Launch Vehicles Using Object-oriented Programming

The aim of this study is to model launch vehicles with focus on 3-DOF trajectory optimization using a modular approach. Despite the large number of operational launch vehicles, they usually consist of basic components and subsystems. In other words, a launch vehicle is an assembly of stages, which in turn is divided into propellant system and engine, and the engine is an assembly of basic components such as pumps, turbines, combustion chamber, and nozzle. To allow future extension and reuse of the codes, a modular structure using object-oriented programming is used. Two formulations of state equations of the trajectory and two optimization methods are described. The launch vehicle performance will be measured by payload mass for a given mission. The simulations of the VLS-1, Ariane 5 and VLS-Alfa were performed and showed good agreement with the literature.

Особенности моделирования инструментально-целевого оценочно-результативного комплекса когнитивно-прагматической программы К. Кинчева в пространстве «героической» эпохи русской рок-культуры

This article considers the try of theoretical comprehension of general principles of target evaluative-effective block of of K. Kinchev’s cognitive-pragmatic programs (CPP) in terms of the author’s linguoculturological theory of CPP modeling within the Framework of “Heroic” Epoch of Russian Rock Music. The CPP that consists of three basic subsystems of cognitive-pragmatic sets (CPS) (target, self-identification, instrumental) and evaluative-effective (secondary synthesized) subsystem is considered as a specific, dynamic and transforming cognitive-mental structure that accumulates the personality consciousness work (subject-source – subject-interpreter), where the most important components of cognitive (the system of genetic codes), the conceptual national-specific (system of culture codes) and the linguistic (the system of sign units of different types) of the world are reflected in a highly concise conceptual form and in a special way. K. Kinchev’s CPP is built on a special model. Not a separate basic subsystem of the target installations but a special instrumental-target complex is formed on the basis of the general abstract goal. At the heart of his modeling lies the dialectical duality of the rock poet’s consciousness, based on the unity and struggle of the positive (the target component of the CPS) and the negative (instrumental component of the CPS) beginnings. It is important that the destructive energy of the revolutionary operational-instrumental strategy, based on the principles of total rebellion and destruction, gradually neutralizes (blocks) the positive content of the target component. This naturally leads to a change in its conceptual status from constructive to destructive. As a result, an evaluative-effective instrumental-target CPS complex begins to form in the space of Kinchev’s CPP, within the framework of which the subject-source comes to the self-analyzed conclusion that none of the goals set has been realized. All this leads to a deep spiritual and creative crisis and the realization that the “heroic” version of the CPP has run out of steam and requires a serious modernization of all the basic subsystems.

A Review on Autonomous Driving Systems

Autonomous vehicles are one of the promising solutions to reduce traffic crashes and improve mobility and traffic system. An autonomous vehicle is preferable because it helps in reducing the need for redesigning the infrastructure and because it improves the vehicle power efficiency in terms of cost and time taken to reach the destination. Autonomous vehicles can be divided into 3 types: Aerial vehicles, ground vehicles and underwater vehicles. General, four basic subsystems are integrated to enable a vehicle to move by itself which are: Position identifying and navigation system, surrounding environment situation analysis system, motion planning system and trajectory control system. In this paper, a review on autonomous vehicles and their related technological applications is presented to highlight the aspects of this industry as a part of industry 4.0 concept. Moreover, the paper discusses the best autonomous driving systems to be applied on our wheelchair project which aims at converting a manual wheelchair to a smart electric wheelchair

Conceptual model of strategic management process of the international economic performance system of an enterprise.

The article shows management process during the implementation of the development strategy of an enterprise’s international economic performance (IEP) as a complex system, which includes processes, operations, elements. Strategic management process of IEP is a higher form of informational interaction, which cannot be effective without high-intellectual memory (supported with a computer). It reflects the functioning of strategic management system of IEP and is a complex phenomenon, which contains the target subsystem, providing subsystem, normative and legislative subsystem and management subsystem. In their turn, the subsystems mentioned above consist of partial processes, operations, and elements. Any strategy management will be effective if there are at least two channels: informational (direct and reverse) and energy (motivational) channel. The effectiveness of strategy implementation is determined with the level of sufficient information for managers of all levels and the motivational system. Conceptual model of strategic management process of IEP of an enterprise is suggested, which is based on the system approach and represented as a set of the following basic subsystems: X – target subsystem, Y – providing subsystem, ХY – normative and legislative subsystem, Z – management subsystem. The X axis – System – illustrates management cycle during the implementation of IEP strategy (a set of stages, processes, functions which should be carried out to achieve the goal (get the result). The Y axis represents the implementation of the goals and processes and defines means of the rational goal achievement. Strategic management subsystem (axis Z) reflects the implementation of general strategic management functions of IEP on the background of accumulated experience (memory). Such system of relations requires the improvement and stabilization of the system of laws, regulations, instructions, orders, which form normative and legislative framework (axis Х Y). It will determine and establish the rules of the game at competitive international markets. Each of the subsystems mentioned above forms its own technical and economic indicators (TEI-1 TEI-2, TEI-3, TEI-4), which are integrated into synthetic management criteria of IEP (TEI-5).

Semidiscrete Integrable Nonlinear Schrӧdinger System with Background-Controlled Intersite Resonant Coupling. Short Summary of Key Properties

The most featured items characterizing the semidiscrete nonlinear Schr¨odinger system with background-controlled intersite resonant coupling are summarized. The system is shown to be integrable in the Lax sense that makes it possible to obtain its soliton solutions in the framework of a properly parametrized dressing procedure based on the Darboux transformation accompanied by the implicit form of B¨acklund transformation. In addition, the system integrability inspires an infinite hierarchy of local conservation laws, some of which were found explicitly in the framework of the generalized recursive approach. The system consists of two basic dynamic subsystems and one concomitant subsystem, and its dynamics is embedded into the Hamiltonian formulation accompanied by the highly nonstandard Poisson structure. The nonzero background level of concomitant fields mediates the appearance of an additional type of the intersite resonant coupling. As a consequence, it establishes the triangular-lattice-ribbon spatial arrangement of location sites for the basic field excitations. At tuning the main background parameter, we are able to switch system’s dynamics between two essentially different regimes separated by the critical point. The physical implications of system’s criticality become evident after a rather sophisticated procedure of canonization of basic field variables. There are two variants to standardize the system equal in their rights. Each variant is realizable in the form of two nonequivalent canonical subsystems. The broken symmetry between canonical subsystems gives rise to the crossover effect in the nature of excited states. Thus, in the under-critical region, the system supports the bright excitations in both subsystems; while, in the over-critical region, one of the subsystems converts into the subsystem of dark excitations.

Impact of nonlinearity on bolt forces in multi-bolted joints: A case of the assembly stage

This article concerns modeling, computation and analysis of multi-bolted joints in the assembly stage. The physical joint model is introduced as the assembly of the following three basic subsystems: a set of fasteners (bolts), a flexible joined flange and a contact layer between it and a rigid support. The finite element method (FEM) is used for modeling. Bolts are replaced by the bolt models of the spider type. The joined flange is modeled with spatial finite elements. As a model of the contact layer, the Winkler contact layer model is adopted. The truth of the theorem has been tested, according to which nonlinear characteristics of the contact layer may have an insignificant impact on computational final values of bolt preloads in the case of sequential tightening of the joint. The results of the calculations for the selected multi-bolted joint are given and compared with the experimental results. Conclusions of paramount importance to the engineering practice are comprised.

Development of global production networks in a global environment

Production systems in the structure of economic systems occupy the most fundamental place and act as both initial and basic subsystem of any economic development. There is a tendency to change the forms of production and the study of these process systems poses a wider aspect of their dynamics analysis. The article tries to prove both theoretically and practically that global production networks are one of the most important factors in the innovative transformation of countries and regions. It is concluded due to global production networks, being the channel for the transfer of global knowledge and technical know-how to regional structures, regions of the former periphery have quickly become developed, innovative regions with a specialization in the sector of highly qualified services, production of high-tech products, and generation of scientific knowledge. For transnational companies global production networks reduce their costs and financial risks by sharing with other companies, as well as global division of labor, an important part of global production.
