Production of and Supply of the Army with Small Arms on the Eve of the Russo-Turkish War (1877–1878). A Brief Overview of the Russian Military Industry

In the wake of the Crimean War, the upper military circles in Russia changed their thinking with regard to firearms. General Milyutin became Minister of War. It was the time when Alexander II reigned over Russia. In 1856, the calibre of Russian firearms was reduced to 6 inches, or 15.24 mm. The process of re-equipping the Russian army with M1856 rifles using expanding Minié bullets was launched. These rifles demonstrated that the percussion systems had reached the limit of their capacity for improvement. Nothing else could be improved in terms of their firing speed. Despite the resistance of the conservative military circles, Milyutin encouraged new inventions, and the 1860s became a period of experimentation with firearms. Some new cartridge systems were introduced. The high-quality M1856 percussion rifle was not destined to take part in war times, but the Russian army had been fully equipped with it for a short period of time. Almost all systems of the 1860s were based on this rifle. Over 10 systems of firearms with an internal needle fuse were proposed to the weapons commission. In 1866, the Englishman Karle proposed his own system with an internal needle fuse. Krnka, Berdan I, and Berdan II came next. After 1866, the Terry-Norman, Karle, and Krnka rifles entered the Russian army. These systems were developed on the basis of the 6-line M1856/58 rifle. The latter was converted into a rear-loading rifle. In 1869, the Krnka rifle was chosen as the main system, which became the main weapon of the Russian army in the following years. At the beginning of 1877, there were 613,297 Krnka rifles, 150,868 Karle rifles, 17,810 Berdan I and 325,254 Berdan II rifles in the Russian army.

Impact of Modern Technologies on Combat and Military Decisions

The history of the society development and its scientific and technological progress is constantly correlated with the history of wars. The desire to raise a person’s standard of living, the rapid pace of life and the aspiration to its high quality have always depended on inventions, technological innovations and the continuous process of development. Military science and the military industry are no exception. The importance of using modern technologies and precision intellectual weapons in a 21st century war is discussed. The issue of reconnaissance drones and the kinetic-strike capability of drones in combat is highlighted, as well as their support by space-based systems. This opened a new era in the art of modern warfare and pointed to the transformation of modern warfare. The article discusses features that have actually emerged in combat in airspace and cyberspace. All the challenges and problems that accompany military decision-making process are shown in the synthesis of these actions. The role and significance of reconnaissance and fighter drones in modern large-scale or local combat operations, especially for a small country like Georgia, are also discussed.

The Research on Operation Automation Model for Information Equipment

Privilege control is an important problem to be solved in the operation of the intranet network of military industry. Solidifying the operation process and replacing the operation personnel with machines to complete configuration changes can reduce the frequency of manual operation by privileged personnel, thus limiting the operation privilege and improving the security of intranet network. Aiming at the high security and high efficiency requirements of operation of intranet information equipment, this paper designs an operation automation mode. Aiming at the problem that it is difficult for tools to adapt to heterogeneous equipment, this paper studies the commands adaptive technology for heterogeneous equipment based on abstract atomic operation. In addition, the model and technologies are verified by a specific scene of equipment location change. The results show that the above model and technologies achieve the goal of ensuring the security of operation and improving the efficiency of operation.

ORGANIZATION OF INTERACTION WITH VIRTUAL REALITY BASED ON A RUNNING PLATFORM FOR COMPREHENSIVE TRAINING OF SPECIALISTS

Одним из современных инструментов организации процесса обучения специалистов является использование виртуальных тренажерных комплексов, позволяющих смоделировать штатные и аварийные сценарии профессиональной деятельности и выработать необходимые компетенции у обучающихся. Существующие подходы к взаимодействию с виртуальной реальностью в рамках тренажерных комплексов основаны на использовании различного рода контроллеров, что негативно сказывается на иммерсивности процесса обучения. Контроллеры также не позволяют смоделировать физическую нагрузку, возникающую при ходьбе или беге при подготовке специалистов в ряде областей (МЧС, военная отрасль, горнодобывающая промышленность и другие). Для решения этой задачи необходимо использование различных беговых платформ. В рамках исследования выявлены определенные проблемы существующих подходов к взаимодействию с виртуальной реальностью посредством беговой платформы. Для их решения предлагается разработка новых методов управления платформой. В работе рассмотрено несколько алгоритмов управления платформой: линейный, нелинейный и нелинейный модифицированный. Представлено математическое описание алгоритмов и проведены экспериментальные исследования, позволяющие выбрать оптимальный алгоритм управления в соответствии с набором определенных метрик. Использование разработанного алгоритма управления позволит улучшить качество взаимодействия обучающего с виртуальной реальностью на беговой платформе. Полученные результаты могут быть использованы при организации процесса обучения специалистов с применением систем виртуальной реальности One of the modern tools for organizing the training process for specialists is the use of virtual training complexes, which make it possible to simulate regular and emergency scenarios of professional activity and develop the necessary competencies for students. Existing approaches to interacting with virtual reality within the framework of training complexes are based on the use of various kinds of controllers, which negatively affects the immersiveness of the learning process. The controllers also do not allow simulating the physical activity that occurs when walking or running, which is necessary when training specialists in a number of areas (Ministry of Emergency Situations, the military industry, the mining industry, and others). To solve this problem, it is necessary to use different running platforms. The study identified certain problems of existing approaches to interacting with virtual reality through a running platform. To solve them, we propose to develop new methods of platform management. The paper considers several algorithms for platform control: linear, nonlinear and nonlinear modified. We present a mathematical description of the algorithms, we carried out experimental studies, which make it possible to choose the optimal control algorithm in accordance with a set of certain metrics. The use of the developed control algorithm will improve the quality of the teacher's interaction when interacting with virtual reality on the running platform. The results obtained can be used in organizing the process of training specialists using virtual reality systems

Improved LEACH protocol for increasing the lifetime of WSNs

<p>Recently, wireless sensor network (WSN) is taking a high place in several applications: military, industry, and environment. The importance of WSNs in current applications makes the WSNs the most developed technology at the research level and especially in the field of communication and computing. However, WSN’s performance deals with a number of challenges. Energy consumption is the most considerable for many researchers because nodes use energy to collect, treat, and send data, but they have restricted energy. For this reason, numerous efficient energy routing protocols have been developed to save the consumption of power. Low energy adaptive clustering hierarchy (LEACH) is considered as the most attractive one in WSNs. In the present document, we evaluate the LEACH approach effectiveness in the cluster-head (CH) choosing and in data transmission, then we propose an enhanced protocol. The proposed algorithm aims to improve energy consumption and prolong the lifetime of WSN through selecting CHs depending on the remaining power, balancing the number of nodes in clusters, determining abandoned nodes in order to send their data to the sink. Then CHs choose the optimal path to achieve the sink. Simulation results exhibit that the enhanced method can decrease the consumption of energy and prolong the life-cycle of the network.</p>

Development of the Russian industrial base and technology for the production of artillery weapons in the 18th century

The purpose of the research is to reveal the features of the creation and activity of the Russian military industry for the production of artillery weapons and ammunition in the 18th century. The article deals with issues related to the accelerated development of industry under Peter I, especially metallurgy, associated with the Great Northern War (1700-1721). Attention is drawn to the fact that due to the construction of a group of state-run private iron foundries and ironworks, four industrial districts were formed – Tula, Olonets, the Urals and St. Petersburg. These districts had for a long time been the main arsenals for the production of artillery weapons for the Russian army. The author focuses on the aspects of improving the quality of products produced by weapons factories in the 18th century. Scientific novelty consists in an interdisciplinary consideration of the issue involving the works of authors whose works were published in the pre-revolutionary, Soviet and modern periods and in the introduction of previously unpublished sources into scientific circulation. It is concluded that the development of the organisational structure of the Russian army caused an increase in the production of artillery weapons and ammunition and the creation of the necessary amount of stocks of these weapons to meet the current needs of the army and navy.

Effect of Zr on the Microstructure and Mechanical Properties of Al-Zn-Mg-Cu Alloy with High Zn/Mg Ratio

The high-strength Al-Zn-Mg-Cu alloy has broad application prospects in high-end equipment manufacturing fields, such as aerospace, national defense and military industry, and transportation. However, the grains of Al-Zn-Mg-Cu alloy are coarse, and the grains further grow after heat treatment, which seriously reduces the mechanical property of alloy castings. Therefore, the study on reducing the grain size of the cast alloy was carried out by adding Zr element and applying electromagnetic stirring treatment technology, as well as suppressing the recrystallization of the aluminum alloy during the heat treatment process. The results show that adding Zr element reduced the grain size by 30%, the tensile strength increased by 50 MPa, and the elongation increased by more than 10%.

3D Reconstruction Human Body From Anthropometric Measurements Using Diversity Control Oriented Genetic Algorithm

3D digitalization of the human body has been studied extensively for various applications in anthropology, ergonomics, healthcare, entertainment and fashion industries. There are different methods and approaches to reconstruct the 3D body model namely using RGB cameras, depth cameras, scanning systems or anthropometric measurements of the human body. Generally, most of existing approaches have to tackle issues relating to security of personal data, the impact of the surrounding environment, cost of 3D scanning systems and complication of anthropometric measurements. This study proposes a method using simple body measurements and given body shapes to digitalize the human body. The effectiveness of proposed method is evaluated and demonstrated based on two datasets: a synthetic dataset generated from a parametric model and a real dataset on Vietnamese collected by Viettel Military Industry and Telecoms Group (Vietnam).
