THE COMBAT ENGAGEMENT (COMBAT EPISODE) LIFE CYCLE INTERACTIVE THREE-DIMENSIONAL VISUALIZATION CRITERIA AND INDICATORS SELECTION

The russo-Ukrainian war is generally characterized as an artillery war, since the main burden in it is the massive use of artillery. However, this war is distinguished from others by the use of various tactics, some of that repeat the tactics of the past, only at a higher technical level, and the newest tactics that have appeared thanks to the advent of modern weapons and military equipment, the which principles are based on the latest technical achievements. The specified circumstances require a careful and more detailed consideration (research) of these tactical techniques on such issues as the reasons for their occurrence, the number of participants, the course of the battle (combat episode), its result, analysis and development, practical recommendations that can be combined into a single concept of the life cycle, eliminate identified shortcomings or provide recommendations for improving individual positions in this matter. For this purpose, it is advisable to reproduce and reconstruct the life cycle of the combat engagement or combat episode that occurred. One of the means of reproducing the life cycle of a combat engagement (combat episode) is interactive three-dimensional visualization. Therefore, in order to create an interactive three-dimensional visualization model (animation) of the life cycle of a combat engagement or a combat episode, that would correspond as close as possible to real events, it is desirable to determine the criteria and indicators that characterize these events. The interactive three-dimensional visualization of the life cycle of a combat engagement or combat episode criterion can be the completeness and reliability of information, and the indicators - dynamism, evaluation of the effectiveness of combat operations and characteristics of the space (locality) in which the combat engagement (combat episode) took place.

Conceptual Framework for Unified E-Government Web Platform

Abstract Technological development has an impact on various areas, and governments from all over the world search to make a smooth transition from traditional to digital, by adopting dedicated software solutions aiming to facilitate the interaction of citizens with public institutions. These platforms are designed to improve the citizens relationship with government by facilitating various processes and tasks. The importance of having a unified web platform is easily justified. Citizens are no longer in need of searching different platforms for their specific needs, dealing with a lot of interfaces and accounts, as all are gathered in one, maintaining a robust, complex system that is easy to use. Therefore, they would benefit from an integrated digital environment, that meet their needs and expectations, also providing security and privacy of confidential and personal information. The authors present the value of creating such an environment, that has a high technical level, that is user-centered and accessible for interactions between citizens and government. Designing and implementing a unified e-government web platform requires the analysis of various factors and aspects such as user interface, processes, services, security measures, integration with social media platforms, collaborative environment, and many others. First, an investigation on specific literature was made to offer a context to the present research and be used as a starting point, highlighting the main factors related to e-government and the impact of this type of platforms. The model proposed by the authors encapsulates considerations on both sides: government and citizens to offer a detailed understanding on e-government platforms.

The history of the development of French Savat boxing

This article highlights the history of the development of French Savat boxing. It is indicated that French boxing savat is a spectacular form of martial arts that is gaining popularity in Ukraine, and therefore the question of studying the history of its development is relevant. The purpose of the article is to get acquainted with the history of the development of French Savat boxing. The final recognition of the respectability of sawat came in 1924, when it was included as a demonstration sport at the Olympic Games in Paris. In 2008, Savat was recognized by the International University Sports Federation (FISU) - this recognition allows the World Federation to hold official university world championships; the first was held in Nantes, France in 2010. The twenty-fifth anniversary of the founding of the International Savat Federation in March 2010 was marked by a visit to Lausanne to meet the President of the International Olympic Committee, Jacques Rogge. FISav President Gilles Le Dugot received a souvenir with the image of the Olympic rings. In April 2010, the International Sawat Federation was accepted as a member of SportAccord (formerly known as AGFIS) - a major step forward towards Olympic inclusion. However, the history of the development of French Savat boxing was not conducted by Ukrainian scientists. Studying the specifics of this sport will allow a deeper understanding of not only the sport itself, but also the peculiarities of the worldview and aesthetic preferences of the French people. An in-depth study of the cultural history of Savat through a historical lens will help to more vividly present the uniqueness and value of this tradition. This can interest and encourage young people to engage in French boxing, not only young men, but also girls, and it will inspire young athletes to reach the heights of sportsmanship. Conclusion. If the Europeans discovered the French boxing savat a long time ago and are developing it at a high professional and technical level, this sport is relatively young in Ukraine. Therefore, the scope for research in this area is large. French boxing sawat is an interesting and spectacular sport, which owes its technical elements. Therefore, it is worth paying great attention to the study of various aspects of this type of martial arts.

Optimal plastic recycling system and technology development could accelerate decarbonization: A case study from Japan

This study provided a geographic and technical matching approach supporting low-carbon style recycling systems, demonstrated using polyvinyl chloride waste (PVCW) generated in 2018 in Mie Prefecture, Japan. From a carbon dioxide (CO2) emission basis, mechanical/material recycling (MR) and energy recovery facilities were all allocated full capacity; however, parts of chemical recycling facilities were excluded in the optimal solutions. From the spatial distribution of the allocated result, we confirmed a trend that to achieve the minimum total emissions, the matchings from pretreatment to recycling facilities were done based on a nearby priority rule. From an emission reduction basis, MR accounted for the major proportion of total reductions which was similar to that accessed from an emission basis. Thus, the promotion of MR should be prioritized at the current technical level when optimizing emissions of the whole lifecycle. The number of facilities allocated were substantially reduced; meanwhile, the averaged emission reductions per ton of PVCW disposed were increased from the current level (2.93) to the near-future level (4.99 t-CO2 t−1). Thus, we concluded that this optimization under a higher technical level was effective to make the current recycling system with more emission reductions (low-carbon environmental effect) and require fewer disposal facilities (cost-saving economic effect). Meanwhile, certain long-distance routes found in solutions implied that technical parameters were more important than geolocation parameters to achieve maximum emission reductions.

Изменение напряженно-деформированного состояния элементов опорно-поворотного устройства кранов при эксплуатации

Despite the high technical level of hoisting equipment purchased abroad, a catastrophic failure of the slewing bearings of these cranes occurs after 3-5 years of service instead of the regulated 15 years. The most characteristic are: wear of 6-polyamide cassettes, cages of gear teeth and turntable; rolling elements falling out of the turntable; squeezing out the sealing tape. To identify the hidden cause of premature failure of the slewing rings of «Liebherr» cranes, the authors carried out the experiment during loading and unloading operations, which shows the tendency of warming up the elements of the slewing support, considering the cyclic nature of the crane operation. It has been established that this process is linear both for cassettes (polyamide 6 material), in which the rolling elements are located,and for the rolling elements themselves (bearing steel). For 5 loading cycles, the rolling elements warm up to a 40 mm depth to a temperature of about 40-45° C. The proposed working hypothesis allows identifing the hidden cause of premature failure of the slewing support of «Liebherr» cranes operating in central Russia. A change in the stress-strain state of the cassette is established, leading to an increase in wear of the cassettes and rolling elements, since stresses arise between the end of the roller surface and the cassette in the direction of the contact plane.

Vertical Farms: A Sustainable Solution to Urban Agriculture Challenges

Vertical farms are considered to be a powerful response to the shortage of future agricultural cultivation space, which can achieve higher agricultural output in cities and alleviate food shortage. This paper focuses on the characteristics of vertical farms, takes the Plant vertical farm in Chicago as an example, describes its design and performance, analyzes its advantages and design principles, and raises some problems that need to be solved. Vertical farms can expand the yield of crops and simulate the environment required for crop growth and development. The success of The Plant is mainly due to the following aspects of the design: saving raw materials and waste disposal costs through the use of waste, staggered electricity consumption and the use of insulated structures to maximize the savings in energy costs, and ultimately enabling the vertical farm to achieve the ability to compete with traditional agriculture. The vertical farm finally achieved the ability to compete with traditional agriculture. It is worth noting that although the small-scale pilot projects of vertical farms have achieved some success, there are still many constraints to be overcome in expanding the scale of vertical farms because of their high construction and operation costs and high technical level.

How Can Sustainable Business Models and Innovative Value Chains Accelerate the Transformation of Electric Vehicles?

Limited resources, climate change and urban mobility lead to a changed mobility behavior in population. Automobile manufacturers are responding to these new challenges by developing electric vehicles that have already reached a high technical level. Ever higher ranges and high reliability show that electric vehicles are comparable to vehicles with internal combustion engines. Nevertheless, manufacturers are failing in selling these vehicles in sufficient numbers without substantial subsidies from local states. Therefore, companies are forced to reconsider and develop their business models because existing business model approaches do not sufficiently cover the requirements for the business of electromobility. Sustainable business models are a promising solution, as they consider economic aspects as well as elements of environmental friendliness and social aspects and are therefore a good basis for electromobility. For a successful sustainable business model for electromobility also a comprehensive ecosystem with all necessary stakeholders of the various stages of the value chains is needed and forms the basis for a newly designed framework. However, the framework can not only be used for business models for electric vehicles but can also be used for other components of electromobility which has been examined in a case study with charging stations to illustrate the applicability.

Marco Topchii’s style in the context of modern world guitar performance

Statement of the problem. Marko Topchii (1991) is one of the famous Ukrainian guitarists who began to conquer the music world at an early age. Winning in competitions (more than 90 times), performances in the world’s most prestigious concert halls (Carnegie Hall, Corto Hall, conservatories of San Francisco, Madrid, Vienna, Bologna) are the result of immense talent and great professional work. The young guitarist is one of those who expand the guitar repertoire by creating arrangements for guitar, in particular of works by J. S. Bach, M. Ravel, M. Mussorgsky. These facts contribute to the relevance of the topic of the article and create a context for the theoretical research of M. Topchii’s performance principles. Recent research and publications. A number of works are devoted to the theme of musical / composer’s thinking (Dys, 1989; Kotlyarevskiy, 1989; Malyi, 2018), guitar thinking and style (Tkachenko, 2008, 2012; Nikolaievska, 2008), M. Topchii’s performance style (Chechenia, 2021, 2016), “musical interpretation” (Moskalenko, 2013), “performance style” (Martienssen, 1930; Katrich, 2000; Tkach, 2012). The purpose of the study is an attempt to identify the features of M. Topchii’s performance style through the context of shaping his musical thinking, communication, social and cultural paradigm and worldview. The scientific novelty is explained by the lack of study of M. Topchii’s personality in Ukrainian and world musicology. M. Topchii’s performance thinking is revealed on the example of the analysis of his own transcriptions of J. S. Bach’s Choral Prelude “Ich ruf zu Dir, Herr Jesu Christ” and M. Mussorgsky’s suite “Pictures from the Exhibition”. The study uses such methods of contemporary cognitivism as historical and cultural (research of the evolution of guitar schools, performance, development of M. Topchii’s style and thinking) and interpretative (identification of principles of performance / interpretation of works); comparative method of analysis of M. Topchii’s style in the context of guitar performance. Results and conclusion. M. Topchii’s style is a concentrated combination of the best achievements of guitar performance schools, which originate from A. Segovia and F. Tarrega. In the context of guitar art, M. Topchii is a unique performer, which is due not only to the number of victories in international competitions and performances on the world’s most prestigious stages, but also to the fact that M. Topchii demonstrates original interpretation of musical works, depth of understanding of the composer’ idea and high technical level of playing the instrument. These qualities make up his unique performance style – emotional, monolithic, crystallized.
