Calculation of Angular Coordinates for the Control System of a Two-Link Industrial Robot Manipulator
Authors: Glushko S. P. 
Published: January 2023

Introduction. One of the tasks of two-link manipulators of industrial robots that move the end-effector along complex trajectories (e.g., robot welder) is associated with the need for careful programming of their movement. For these purposes, manual programming methods or training methods are used. These methods are quite labor-intensive, and they require highly qualified service personnel. A possible solution to the problem of programming the manipulator movements is the simulation of motion with the calculation of angular coordinates. This can help simplify the geometric adaptation of the manipulator in the process of debugging the control program. Therefore, this work aimed at calculating coordinates for programming the control system of a two-link manipulator operating in an angular coordinate system and moving the end-effector along a complex trajectory (e. g., when welding car bodies). Materials and Methods. A two-link robot manipulator designed for cyclically repeating actions in an angular coordinate system was considered. The manipulator consisted of two rotating links: “arm” and “elbow”, which were fixed on the base. The base could rotate, which provided a third degree of freedom. This configuration increased the working area of the manipulator and minimized the area for its placement in production. The movement of the manipulator end-effector could be performed if the kinematics provided its positioning along three Cartesian and three angular coordinates. For software control of robots, including welding robots operating in an angular coordinate system and performing the movement of the end-effector along a complex trajectory, it was required to calculate the angular coordinates of the movement of the end-effector of a two-link articulated manipulator. The robot control system should determine the position of the tool in the angular coordinate system, converting it for user friendliness into x, y and z coordinates of the Cartesian coordinate system. Results. The relations of angular and Cartesian coordinates have been obtained. They can be used for calculating when programming the control system of a two-link manipulator of an industrial robot and organizing the exchange of information between the user and the control system, as well as for checking the accuracy and debugging the movement of the end-effector of an industrial robot through feedback. Discussion and Conclusion. The presented results can be used for software control of a welding robot operating in an angular coordinate system and performing a complex trajectory of the end-effector of a two-link articulated manipulator (gripper). A manipulator operating in an angular coordinate system can be used for contact spot welding when moving the end-effector along a complex trajectory using a positioning or contouring control system. These systems control the movement of the end-effector along a given trajectory with the help of technological commands.

Published: January 2023

Introduction. Life expectancy is, by definition, the average number of years a person can expect to live from birth to death. It is therefore the best indicator for assessing the health of human beings, but also a comprehensive index for assessing the level of economic development, education and health systems . From our extensive research, we have found that most existing studies contain qualitative analyses of one or a few factors. There is a lack of quantitative analyses of multiple factors, which leads to a situation where the predominant factor influencing life expectancy cannot be identified with precision. However, with the existence of various conditions and complications witnessed in society today, several factors need to be taken into consideration to predict life expectancy. Therefore, various machine learning models have been developed to predict life expectancy. The aim of this article is to identify the factors that determine life expectancy. Materials and Methods. Our research uses the Pearson correlation coefficient to assess correlations between indicators, and we use multiple linear regression models, Ridge regression, and Lasso regression to measure the impact of each indicator on life expectancy . For model selection, the Akaike information criterion, the coefficient of variation and the mean square error were used. R2 and the mean square error were used. Results. Based on these criteria, multiple linear regression was selected for the development of the life expectancy prediction model, as this model obtained the smallest Akaike information criterion of 6109.07, an adjusted coefficient of 85 % and an RMSE of 3.85. Conclusion and Discussion. At the end of our study, we concluded that the variables that best explain life expectancy are adult mortality, infant mortality, percentage of expenditure, measles, under-five mortality, polio, total expenditure, diphtheria, HIV / AIDS, GDP, longevity of 1.19 years, resource composition, and schooling. The results of this analysis can be used by the World Health Organization and the health sectors to improve society.

Нефротический синдром, вызванный нуклеотидными вариантами в гене CRB2, является редким и недостаточно хорошо изученным состоянием. На настоящий момент существует лишь несколько сообщений об этой патологии и нет ни одного описания мягкого течения заболевания. Целью настоящего сообщения является демонстрация фенотипических особенностей нефротического синдрома, вызванного мутациями в гене CRB2, и обоснование дальнейшего изучения его генетических причин. На базе нефрологического и молекулярно-генетического отделений ФГАУ «НМИЦ здоровья детей» проведено ретро- и проспективное исследование генетических причин первичного стероидрезистентного нефротического синдрома (СРНС), включившее 250 детей. Среди 250 детей лишь двое имели причинные нуклеотидные варианты в гене CRB2 (0,8% от всех детей с СРНС и 1,21% от детей с выявленными генетическими причинами СРНС). Дети имели разные течение болезни и выраженность экстраренальных проявлений. Выводы: нефротический синдром, вызванный мутациями в гене CRB2, является чрезвычайно редкой патологией. Нами описано два случая с абсолютно разным клиническим течением.
Nephrotic syndrome (NS) with variants in the CRB2 gene is a rather rare condition, and there are only a few reports of its severe course and no one of mild one. The aim of the communication is to demonstrate the phenotypic features of nephrotic syndrome caused by mutations in the CRB2 gene. On the basis of the nephrological and molecular-genetic departments of the Federal State Autonomous Institution “National Medical Research Center of Children’s Health” we performed retro- and prospective study of the genetic causes of primary steroid-resistant nephrotic syndrome, included 250 children. Among 250 children, only two had causative nucleotide variants in the CRB2 gene (0.8% of all children with steroid-resistant and 1.21% of children with identified genetic causes of SRNS). Children had a different course of the disease and the severity of extrarenal manifestations
Decent Work Systems: Management Model Analysis on the Example of Russian Railways
Authors: Gileva K. V. 
Published: January 2023

Decent work governance for modern socio-economic systems is a key goal and a common operating methodology. The current literature does not fully disclose the questions posed, which require the proposal of system management models, formed considering the factors of the external and internal environment that determine the characteristics of management in different sectors of the economy. The purpose of the paper is to update the modern provisions of the decent work theory, the formation of a basic model for managing decent working conditions and its substantive justification on the example of Russian Railways enterprises. For this purpose, the author describes the implementation research work using the methods of interdisciplinary analysis of literature and practical experience, as well as a regulatory framework, professional recruitment, including for the transport industry, strategic documents and concepts in responsible work. Also, the research used the method of counter modeling, which represents the decomposition of the theoretical model into the results of the production conditions, financial and socio-economic activities of a particular enterprise. As a result of the work carried out, the author built a model for managing suitable labor at the enterprise based on the scheme of suitable labor management, also relying on empirical data and the regulatory framework of Russian Railways. This model has become a methodological basis for analyzing the situation of decent labor management at the enterprises of Russian Railways. The data obtained testify to the operation of managerial, legal, supervisory, institutional and financial mechanisms for managing suitable work. The practice of applying the results of the study led both to positive results and identified problem areas that cause socio-economic risks in implementing personnel policy measures of Russian Railways.
