Presented is the study of developing a theory of practice of synergetic design and virtual physical laboratories to increase the level of compliance with reality and reduce the level of learner’s immersion in the virtual environment. The authors considered one of the objectives leading to the achievement of the goal, the use of synergistic aspect in the digitalization of physical education which allows consolidating virtuality and reality of the surrounding world, and use the “positive” effects to form new physical knowledge of the learner. The authors defined the requirements for digital physics labs, which should provide realism, interactivity, automation and virtualization. The distinctive feature of the research is the synergetic aspect, which consolidates subject knowledge, mathematical modeling and philosophical reflection. The combination of these components made it possible to synthesize a new form of digital physical laboratory and to perform its software implementation based on the developed scenario diagram for the incoming actors. The software implementation of the digital physical laboratory required: preparation of video clips with a series of physical experiments, definition of the laboratory work order (progress) and examples of “return” from virtual reality. The testing of the synergetic aspect and the possibility of its realization was done on the example of a digital laboratory work in the study of the fall of a body.

AbstractWalking as a transport mode is still often underrepresented in the overall transport system. Consequently, pedestrian mobility is usually not recorded statistically in the same manner as it is performed for motorised traffic which leads to an underestimation of its importance and positive effects on people and cities. However, the integration of walkability assessments is potentially a valuable complement in urban planning processes through considering important quantitative and qualitative aspects of walking in cities. Recent literature shows a variety of approaches involving discrepancies in the definition of walkability, the factors which contribute to it, and methods of assessing them. This paper provides a new understanding of the concept of walkability in the European context. Our approach relies on the extension of methodological competence in transportation, spatial planning and geography by linking new measurement methods for evaluating walkability. We propose an integrated approach to assessing walkability in a comprehensive methodology that combines existing qualitative and GIS-based methods with biosensor technologies and thus captures the perceptions and emotions of pedestrians. This results in an increased plausibility and relevance of the results of walkability analysis by considering the spatial environment and its effect on people.

AbstractSex dolls are a complex phenomenon with several diverse possible emotional, sexual and therapeutic uses. They can be part of a broad variety of sexual practices, and also function as a sexual aid. However, the media discourse on sex dolls first and foremost concerns how we perceive the relationship between intimacy and technology. A critical discourse analysis of the Swedish media discourse on sex dolls reveals six themes which dominate the discourse: (a) the definition of what a human being is; (b) a discourse on the (technological and existential) future; (c) a social effort; (d) a loveless phenomenon; (e) men’s violence against women; and (f) pedophilia. Accordingly, this discourse is very conservative and normative in its view of sexuality, technology, and humanity. Overall, the dominant themes do not provide any space for positive effects of technology on human sexuality, and if they do, it is usually as a substitute for something else.

Introduction.The urgency of studying theoretical foundations of budget decentralization for Ukraine is conditioned by the necessity of developing an effective scheme of macroeconomic regulation of social and economic processes in the context of decentralization. The process of social and economic development in Ukraine on a democratic and legal basis is impossible without increasing the role of the local self-government. Decentralization is one of the main motive forces in reforming self-government today. The purposeis deepening theoretical and methodological principles of budget decentralization and theoretical aspects of budget decentralization with the definition of its influence on processes of state regulation in Ukraine. Results.It is substantiated that in modern science theoretical aspects of decentralization are considered in relation to its types. The classification of decentralization types is carried out depending on their characteristics: financial (fiscal) one is the process of distribution of functions, financial resources and responsibility for their use between central and local levels of management; budget one, in the broadest sense, is the division of responsibility between authorities of different levels (including national governments, regional authorities and local self-government bodies) with the management of budgetary resources; in the narrow sense it is the presence of certain functions and powers at the local level, autonomy of local authorities in making independent decisions in the fiscal sphere. Conclusions.It is substantiated that budget and financial decentralization considerably influences the formation of local budgets. It is found that the decentralization course shows both prospects and problems of the Ukrainian development. Grouping the main benefits and positive effects of decentralization is carried out. The research analysis made it possible to establish that decentralization may have the risks and dangers grouped in the article.


1. A great deal of attention has been directed of late years to the development of a rational theory of the aёrofoil. Prof. L. Prandtl and others in Germany have applied the principles of the hydrodynamics of a perfect fluid to the aerofoil with remarkable results, whilst investigators in this country have extended this work and have verified experimentally many of the deductions of the Prandtl theory. The assumptions underlying the work of Prandtl are, however, of uncertain validity, and it has become a matter of great importance to add to existing experimental evidence of the fundamental characteristics of the motion of a viscous fluid round an aёrofoil. With this purpose in view an aerofoil section of fairly high lift coefficient was selected, and a model of it tested in the Duplex Tunnel at the National Physical Laboratory, the field of flow being thoroughly explored with a wind-velocity meter. At the same time the theoretical stream-lines corresponding to inviscid fluid flow were determined experimentally, as described in Part II of this paper. The case considered is that of an aerofoil of infinite span, the flow being two-dimensional. A comparison was made of the theoretical and experimental distributions of pressure over the surface of the aёrofoil, as well as of the two sets of superposed stream-lines. The work has provided an experimental verification of the law of Kutta and Joukowsky, that the product of the mean velocity and density of the fluid and of the circulation (according to the hydrodynamical definition of this term) around a contour enclosing the aerofoil is equal to the lift of the aёrofoil (per unit length). It has further shown that the circulation around the aёrofoil is constant within the limits of experimental error and independent of the contour of integration chosen, provided that the contour line does not at any part approach too near to the aerofoil, and also that it cuts the trailing “wake” approximately at right angles to its core. The lowest value of the circulation found (calculated for a contour as close to the aёrofoil surface as the observations permitted) was about 6½ per cent, less than the value corresponding to the lift coefficient; this is hardly outside the limits of experimental accuracy in the neighbourhood of the aёrofoil.

The deterministic structuring of a surface is having a profound effect on many industrial products by allowing the manufacturer to significantly alter the way in which a surface functions. This has led to a clear need in industry and academia for traceable areal surface texture measurements. To address this need traceable transfer artefacts and primary instrumentation are required. The National Physical Laboratory (NPL) is working on two projects – one to develop areal transfer artefacts and one to develop a traceable areal surface texture measuring instrument. The authors describe the development of the artefacts and instrument, and present some of the challenges that are still required to be able to offer an areal traceability measurement service to industry. The instrument has a working volume of 8 mm  8 mm  0.1 mm and uses a co-planar air-bearing slideway to move the sample. It also uses a novel vertical displacement measuring probe, incorporating an air-bearing and an electromagnetic force control mechanism. The motions of the slideway and the probe are measured by laser interferometers thus ensuring traceability of the measurements to the definition of the metre. The artefacts were manufactured using a range of machining technologies and in a range of geometries suitable for stylus and optical based instruments.

We present a method to directly predict the hydrodynamic response of a Remotely Operated Vehicle (ROV) as it transitions through the wave-affected splash zone during launch or recovery. ROVs are commonly used in offshore operations and for many different purposes. They are usually deployed from a purpose built Launch and Recovery System (LARS) located on the open deck of a surface ship. Current industry practice used for LARS design is to use a pre-defined dynamic amplification factor (DAF) together with high factors of safety. However, this does not properly account for the influence of different sea states and operational profiles. We therefore propose an improved method to directly predict the hydrodynamic response of an ROV as it transitions through the wave-affected splash zone. We apply the approach to a trencher ROV and validate using physical experiments completed in a wave tank. We demonstrate the need to for an accurate definition of the added mass and damping characteristics of the ROV. The method is incorporated into OrcaFlex for direct use within the design and analysis of a LARS system.

The most characteristic problem of the current stage of modernization of higher education is the training of future physics teachers who are ready to adapt to the conditions of a rapidly changing digital society and are able to independently set and solve professional problems. The purpose of the article is to identify the features of the use of digital technologies in improving the demonstration experiments of the physics course. The leading method to study this problem is the modeling method, the study and analysis of psychological, pedagogical, scientific, technical and methodological literature. The use of computer models of various physical processes and phenomena contributes to the effectiveness of teaching students the physics course, allows them to understand the mechanisms of physical phenomena and processes. In this regard, at present, the Abai Kazakh National pedagogical University pays great attention to the development of a technical base for the use of digital technologies in the training of future physics teachers, and electronic resources are being developed for use in teaching physics. By using computer models of experiments and demonstrations, it is possible to compensate for the lack of equipment in the physical laboratory and thus teach students to independently acquire physical knowledge during a physical experiment on virtual models, that is, there is a real opportunity to form students ' creativity and increase cognitive activity in physics.

ABSTRACT Considering the frequent flooding of urban centers, the financial limitations and the inefficient management of Urban Drainage (UD) systems in Brazilian municipalities, it is necessary that projects be developed efficiently. These objectives are achieved with the correct definition of the diameter and galleries slope, resulting in adequate hydraulic ratios. It is also necessary to guarantee the flow without backwater, by verifying the energy grade line along the network. There are software capable of assisting the calculation, which, however, do not report optimized solutions. A vector-based numerical modeling is presented for the optimized sizing of a UD gallery system. This model was applied in an area and its results were compared with those obtained by two software in the Brazilian market. It is demonstrated the optimization developed contributes to increases the efficiency in the design. The main scientific contributions are: to characterize and model the typical design slopes, to obtain the optimum slope combined with the smaller diameter; to explore the potential of the hydraulic ratios above those normally employed, with positive effects on the definition of {D, ig} and the economy in the system; and to implement a recursive solution from a cycle of interdependent information, ensuring accuracy of results.

The most important points in this research of moderate nation are: Definition of the concept of moderation in terms of language  and terminology and the Quranic context, they are rooted origin, and means the moderation in understanding the texts without excessive nor shortening, so that a Muslim brought up on the basis of a balanced education. A clarity for contrary statements to the moderation as extremism and estrangement, and to clarify their far distance from Islam, and what they produced and deviant ideas serious;y tarnished the beauty of the religion and its reality. Moderation has left pretty positive effects on the Muslim individual, including integrity and straightness, and produced positivity at the level of thinking and action, and the rush towards the good, virtue, and construction. The banner of moderation has been carried by men who put their marks in history, was guided, renewed the fact of the true religion, and they were the best model for this nation's predecessor and the safety of their approach.

The 2030 Agenda for Sustainable Development stipulates the need for economical use of natural resources and the introduction of green technologies to ensure the harmonious reconciliation of economic, social, and environmental development. However, the problems associated with the definition of the country’s sustainable development in conditions of global threats are far from being solved and require further theoretical efforts. So,the purpose of the article is to form a methodological approach to define the country’s sustainable development in conditions of global threats. The methods used in this study are the comparative and statistical analysis , the systematic approach – in creating the mechanism of ensuring the sustainable development of the world in conditions of global challenges. The analysis results show that the methodological approach allows assessing the country’s sustainable development considering global threats, which, in turn, policy adjustments to strengthen sustainable development in global crises. This study concludes that globalization’s process causes various changes; the positive or negative vector of these changes largely depends on the level of sustainable development of the country and the country’s position in the world economy. The higher the country’s sustainable development indicators, the more positive effects of globalization the state receives.
