Kind:Electronic copy
Annotation:В статье представлены результаты проведенных в условиях лаборатории радиационного контроля с использованием гамма - спектрометрического комплекса СКС-07П измерений образцов строительных, отделочных материалов, сельскохозяйственной продукции (меда), на содержание в них следующих радионуклидов: 137Cs, 40K, 226Ra, 232Th для города Пензы и Пензенской области. Полученные зависимости позволяют утверждать, что существуют зависимости между эсхаляцией радона, видом строительных и отделочных материалов. Кроме того, выявлены сезонные колебания интенсивности выделения радона.

Title:Design of a Simulation Model of a Temperature Sensor under Critical Temperature and Sinusoidal Vibrations
Author:Трофимов Алексей Анатольевич  Фокина Екатерина Александровна  Пономарёв Владислав Николаевич  Здобнов Сергей Александрович  
Type:Article
Kind:Electronic copy
Annotation:Vibration measurement is among the most popular and cost-effective methods for diagnostics of the overall condition of equipment and is of undeniable importance in modern technology. Thanks to this process, manufacturers and consumers can be sure of the reliability and quality of technical systems, as well as prevent possible malfunctioning and failures. Vibration measurements in various fields confirm their versatility and importance in modern technical progress. The measurement of the effects of critical temperatures on a temperature sensor is aimed at determination of possible changes in the accuracy and reliability of the sensor. This will improve the quality of temperature measurement, eliminate inaccuracies and errors in operation of equipment, and increase the efficiency of the equipment under various operating conditions. The research method in this paper is a simulation model of the sensor, which is used to test for vibration and exposure to critical temperatures. Ansys and SolidWorks Simulation software are used to create the model to avoid costly and time-consuming test cycles. The results of the simulation modeling are used to construct diagrams of mechanical stress distribution under sinusoidal vibration and diagrams of temperature distribution under critical temperatures.

Title:Designing a High-Performance Resource Management Module for Real-Time Multiprocessor Systems
Author:Бикташев Равиль Айнулович  
Type:Article
Kind:Electronic copy
Annotation:The In this article the author substantiates a hardware approach to designing the kernel of real-time multiprocessor operating systems. The author also provides possible options for architectural solutions, and considers the formal representation of control algorithms for interacting processes operating in parallel computing systems when they access a shared resource. The theory of event-driven nondeterministic automata was used for formalization. There were obtained equations that describe the procedures for the process of entering the critical interval and remaining there, taking into account the accepted discipline of ensuring priority and mutual exclusion of incompatible events. The exit of the process from the critical section, which makes it possible to synthesize the control module was examined as well. Modeling of a device for 4 inputs of requests to a shared resource in the VHDL language was executed, the results of experimental studies were also provided.

Title:Designing the power supply system of the region with the integration of hydrogen energy facilities
Author:  Пятаев Юнес Кязымович  
Type:Article
Kind:Electronic edition
Annotation:The paper considers the methodology of designing a distribution network by the example of the Penza region in Russia. We performed a simulation of operating modes and optimization of the distribution network topology. The power balance in the power system was performed in autonomous mode. Recommendations were given on the placement of renewable energy sources (RES) on the ground and the selection of their capacity. The total capacity of renewable energy generation facilities exceeds the design load 3 times. A balancing load is included in the power system to increase the efficiency of renewable energy generation facilities. Electrolysis hydrogen stations consume excess electricity generation during the periods of favourable weather conditions. Hydrogen is stored in the warehouses and can be used at the thermal power plants during periods when weather conditions are unfavourable and the generation of renewable energy sources is insufficient to supply the region.

Title:Determination of the parameters of the spray area during electric arc dispersion of the material
Author:Зверовщиков Александр Евгеньевич  Таранцев Константин Валентинович    
Type:Article
Kind:Electronic copy
Annotation:A technique has been developed for determining the free flight distance of a melt particle, which is required to maintain a spherical shape during a final impact. Based on the analysis of flight dynamics, an approximate calculation of the largest critical size of the spray zone for carbide material was performed. The possibility of creating compact devices for the dispersion of hard alloys is substantiated.

Title:Determination of the parameters of typical multi-link dimensional chains (closing link is tension) using recurrent dependencies (Определение параметров типовых многозвенных размерных цепей (замыкающее звено - натяг) по рекуррентным зависимостям.)

Type:Article
Kind:Electronic edition
Annotation:Существующий подход к использованию метода групповой взаимозаменяемости при сборке имеет ряд существенных недостатков: 1) отсутствуют формулы для расчета верхнего и нижнего отклонений составных частей размерной цепи; 2) отклонения подбираются без учета конструкции звеньев; 3) метод применим для количества звеньев не более трех при небольшом количестве групп; 4) расчет методом групповой взаимозаменяемости ограничивается условием равных допусков; 5) расчеты основаны на предположениях об экономической целесообразности увеличения допуска замыкающего звена в n раз без учета возможности такого увеличения, что недопустимо в ответственных механизмах; 6) не отражены размер партии деталей и объем незавершенного производства, как один из факторов экономической целесообразности установления допусков. В связи с этим необходимо усовершенствовать метод достижения точности за счет групповой взаимозаменяемости. В этой статье обсуждаются типичные проблемы, возникающие при решении размерных цепей, в которых замыкающим звеном является натяг.
