Goal. Design development and analytical studies of the productivity of a linear dispenser-doser of dispersed components. Method. A mathematical model of the performance and speed of movement of a linear distributor- dispenser of dispersed components was considered, based on which a nomogram was built to determine the modes of its operation. Constructed dependencies and analysis of the obtained results were carried out with the help of a graphic editor. The results.
In the article, the author elucidates the features of the postmodern approach to asserting the value of peace using the techniques of actionism (performance, happening, art installation, flash mob, etc.). Anti-war actionism is considered as an element of the system of sociopolitical actionism. A set of spectacular forms of non-violent public protest against armed aggression and its consequences are analyzed. The fact that today’s anti-war actionism has gone beyond the narrow artistic environment and entered the broad social dimension is proved.
In the work the automated methods for assurance user’s effective performance are investigated. The structure of the automated system of support of human productivity is developed. For practical implementation, the MEAN technology stack is used, the interaction of its component is described. Automated methods in the form of an application are implemented and its main advantages are determined.
Comparative analysis of the effectiveness of monolithic and cyclic noise protective codes built on "Ideal Ring Bundles" (IRBs) as the common theoretical basis for synthesis, researches and application of the codes for improving technical indexes of coding systems with respect to performance, reliability, transformation speed, and security has been realized. IRBs are cyclic sequences of positive integers, which form perfect partitions of a finite interval of integers. Sums of connected IRB elements enumerate the natural integers set exactly R-times.
The architectural reconstruction and technical refurbishing of the new facility of the School of Performance were concerned with accommodating the needs of teaching, production, and performance in a found space, the basement of Ryerson University’s Student Learning Centre with utilizing of the state-of-the-art technologies. Kyiv Academician Theatre of the Podil, one of the leading drama theatre companies in Ukraine, has finally got the permanent home with the state-of-the-art performing facility.
The improvement of existing electromechanical guidance systems of the armament complex of combat vehicles should be implemented in the direction of increasing the speed and accuracy of positioning. The paper deals with the lifting mechanism of guidance of the package of guides of the multiple rocket launcher BM-21, which is a unit of the armament of the Armed Forces of Ukraine and is typical for many samples of weaponry.
Multiple rocket launchers are vital components in providing fire potential of combat units. Their mobility and target hitting accuracy determinatively impact the combat result. Existing guidance system of array of guides of a combat machine BM-21 is a complicated, inertial system with multiple feedbacks, characterized by back-lashes, gaps, and by limited elasticity of some elements of a mechanical part. It has to ensure required static and dynamic indices (i.e., speed of operation and accuracy of positioning of array of guides).
Pumping stations that provide fluid transportation by pipeline are significant consumers of electricity. Energy overruns due to sub-optimal modes of operation of individual high-power units or sub-optimal number of simultaneously operating less powerful units are quite significant and can have a significant impact on overall energy consumption. Energy overruns at pumping stations also lead to significant overruns in electricity grid elements.
The synthesis and coverage of foreign experience in the organization of production at industrial enterprises has a diverse focus and encompasses methods that increase the productivity of their productive activities in various ways. In this context, the Japanese experience of organizing production deserves special attention. The advantages of its application are demonstrated by Japanese companies that are world leaders in terms of achieved product quality, productivity, stock optimization, in-house and other costs.
In this paper, the comparative evaluation of the performance and code size of cryptographic hash functions SHA-3 and GOST R 34.11-2012 is conducted for the implementation on 8-bit microcontroller family AVR and 32-bit microcontroller cores ARM Cortex M0/M0+/M3/M4.
