The effective organization and utilization of military equipment data is an important cornerstone for constructing knowledge system. Building a knowledge graph in the field of military equipment can effectively describe the relationship between entity and entity attribute information. Therefore, relevant personnel can obtain information quickly and accurately. Attribute extraction is an important part of building the knowledge graph. Given the lack of annotated data in the field of military equipment, we propose a new data annotation method, which adopts the idea of distant supervision to automatically build the attribute extraction dataset. We convert the attribute extraction task into a sequence annotation task. At the same time, we propose a RoBERTa-BiLSTM-CRF-SEL-based attribute extraction method. Firstly, a list of attribute name synonyms is constructed, then a corpus of military equipment attributes is obtained through automatic annotation of semistructured data in Baidu Encyclopedia. RoBERTa is used to obtain the vector encoding of the text. Then, input it into the entity boundary prediction layer to label the entity head and tail, and input the BiLSTM-CRF layer to predict the attribute label. The experimental results show that the proposed method can effectively perform attribute extraction in the military equipment domain. The F 1 value of the model reaches 77% on the constructed attribute extraction dataset, which outperforms the current state-of-art model.

Abstract With the development of technology, modular independent suspension technology has been widely applied on high-movement off-road platforms in the developed world because of the characteristics of offline assembly and full-body lifting. At the same time, after the breakthrough of key techniques such as the stiffness spiral springs, the high dissipation of the shock absorbers, the lightweight of double-wishbone steering mechanism and the non-maintenance bearing, the ability to carry the off-road mobility and armor protection of the military vehicles have been significantly increased. In this case, the application of the modular independent suspension and its current state around the world was explained, that the development of this technology is of great significance to the off-road maneuvering of our military equipment was also represented in this paper.

In the article, based on the analysis of the requirements for the readiness of weapons and military equipment during combat use and the reliability of their operation in the course of combat operations, it was discovered that one of the reasons that causes a discrepancy between the declared failures and real ones may be the incorrect choice and justification of the time distribution function up to the refusal of military means. As a rule, during the development of these tools, the function of distribution of time to failure is chosen by analogy with similar patterns of weapons and military equipment. In the theory of reliability, special attention is given to choosing the function of time-breaking non-response (failures or failures). Therefore, the article deals with the questions of evaluating the effectiveness of functioning of complex systems and methods of modeling the processes of their functioning, taking into account the laws of the distribution of random variables. The discrepancy between the declared irregularity of the military apparatus and the fact that is actually observed in the troops can be explained by the incorrectly accepted hypothesis about the distribution of time to failure. Therefore, the article analyzes the order of the justification of such a function without taking into account the enemy's fire impact and the proposed variant of determining the function of distribution of the time of work until the refusal of the model of military equipment. The article also cites the reasons for the discrepancy between the claimed missile defense equipment and what is actually observed in the troops. The proposed mathematical model of faultlessness, which at stages of designing and design will allow to set requirements to the model of technology with the help of analytical description. The sequence of calculations of non-failure indexes based on the use of Weibull distribution is substantiated.

The basic principles and current state of topographic mapping of the territory of Ukraine are considered. Prior to the proclamation of Ukraine's independence, its territory was covered by topographic maps in the scale of 1:10 000 to 1: 1 000 000, created by the Main Department of Geodesy and Cartography under the USSR Council of Ministers and the Military Topographic Service of the USSR Armed Forces. The interaction of these departments in topographic mapping is highlighted. The topographic study of Ukrainian territory as of 1991 is analyzed in detail. Today the content of most topographic maps of scales from 1:10 000 to 1: 200 000 is characterized by "aging" of information and does not correspond to the current state of the area. The unsatisfactory state of topographic study of the territory led to the unclaimed topographic maps with much outdated information for consumers, and for the military it very difficult to perform combat tasks. The needs of current topographic information users require a significant improvement in topographic maps content. Since the mid-1990s, the creation of national geospatial data infrastructures has become crucial for providing spatial information to the state and society. The basic principles and general requirements for the creation and updating of state topographic maps are now defined by the "Procedure for national topographic and thematic mapping" (2013). The adoption of the Law of Ukraine "On the National Infrastructure of Geospatial Data", giving a powerful impetus to topographic mapping, poses a responsible task of organizational and regulatory and technical support of this process. The issue of obtaining topographic maps from the topographic database requires scientific and technical elaboration, development of appropriate normative and technical documents (guides, principles, instructions, symbols, etc.).

Abstract. The state Coordinate Reference System (CRS) of the Republic of North Macedonia (RNM) has been established a century ago, by the Military Geographic Institute of the Yugoslavia Kingdom. It is in official usage entire period up to day. In international public EPSG registry of geodetic datums, spatial reference systems, Earth ellipsoids, coordinate transformations and related units of measurement, CRS for RNM is recognizable within 3 EPSG codes 6204, 6316 and 8679.First code EPSG 6204 represents current state CRS for the entire country area, based on current law, however unfortunately this CRS is official by the law but it is not used for developing the official spatial data published in geoportals of Agency for Real Estate Cadastre (AREC) and NSDI geoportal of RNM. The second code EPSG 6316 is defined to be used for 6 countries of former Yugoslavia that covers area between 19.5°E up to 22.5°E longitude, which does not correspond with the practical and official usage of CRS for working with spatial data in RNM and CRS law definition in RNM. Third code EPSG 8679 has never been used in RNM, which covers eastern part of RNM and Serbia beginning from 22.5°E.Beside of problems with EPSG codes, default transformation parameters of EPSG 6316 have low accuracy and can not be used for data overlapping with open layers. Therefore, redefined new EPSG codes for state CRS of RNM are proposed in this paper.

Тhe article deals with the results of the Patriotic War of 1812 and the Great Patriotic War of 1941–1945. The analysis of these largest wars in the history of Russian-European relations is carried out, their comparison is made, their nature, character and driving forces are revealed. On the basis of this, it is concluded that both sides have not made the proper conclusions: Europe — in terms of the expediency and consequences of an attack on Russia, thereby violating the will of the iron Chancellor Otto von Bismarck: "Make alliances with anyone, start any wars, but never touch the Russians." Russia — timely opening and preparation for the upcoming tests in relations with Europe. Against the background of more than 200 years of history, the current state of relations between Russia and Europe, which has reached a low level, is considered. Although the leading European states, Germany and France, have not stopped political contacts with Russia, but the content of these contacts has become significantly poorer, the format has narrowed, and the tone has sharpened. In the military sphere, Europe in the Russian direction follows in principle the same course as the United States. Within the framework of NATO, European countries, led by the United States, have taken a number of steps that have restored, so far at a symbolic level, the military confrontation with Russia in eastern Europe. Moscow, for its part, has stepped up its own military activities near its western borders. As a result, Europe has ceased to be the island of security that it remained for the previous quarter of a century. This does not mean, of course, that relations between Russia and European countries are ending. In fact, Russia's practical needs require easing tensions with Europe as its largest trade and economic partner. With this in mind, Moscow has achieved some success in replacing the almost non-existentties with Brussels with meaningful bilateral relations with some EU countries. Despite the fact that the European Union's foreign policy apparatus is unable to form a unified geopolitical, economic and cultural front against Moscow, there is every reason to believe that the Kremlin intends to be guided by this strategy of bilateral relations in the coming years.
