The article contains the main provisions of changing the method of repair, calculating the possibility of loading production positions, calculating the program of repairing wagons, determining the number of ways of their routes, analyzing the shortcomings of flexible asynchronous flow, developing solutions for testing flexible flow in computer simulations. Summarizing this material provides an opportunity to consider and develop a project based on the Stryi Wagon Repair Plant for flexible flow or its modification to increase repair capacity. The article calculates the time of repair of wagons by the flow method and using a flexible asynchronous multichannel method of repair, the graphs show the difference in downtime between the same types of wagons and the type of repair, provided that they are taken in the same condition before repair work. From these calculations, it can be concluded that the streamlined method of repair has exhausted all its resource potential, and will continue to incur the cost of paying employees, maintenance of equipment and other costs associated with production.","PeriodicalId":33465,"journal":{"name":"Zbirnik naukovikh prats'' Derzhavnogo universitetu infrastrukturi ta tekhnologii seriia Transportni sistemi i tekhnologiyi","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69984185","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Technology opens up opportunities and changes the means of waging war. Technology has been a major source of military innovation throughout history. They cause change in war more than any other factor. The tools of warfare have evolved slowly throughout human history, but only in the modern world is there an institutionalized and rationalized mechanism for their constant and systematic renewal.\u0000Higher levels of government spending related to the war have been found to tend to bring some positive economic benefits in the short term, especially due to the increase in economic growth that occurs during the expenditure boom in conflict. However, negative unintended consequences occur either at the same time as the war, or develop as residual effects over time, thereby harming the economy in the long run. At the same time, military conflicts are the impetus for new innovative developments. In crisis conditions, the probability of intensification of modernization processes increases, new branches and sectors of the economy appear, and high-quality structuring takes place.\u0000Thereby, military conflicts, with many negative consequences, are a catalyst for innovation arising from scientific developments in the military sphere, as well as stimulate the industrial development of countries in a high-tech direction based on quality human capital, knowledge and innovation.","PeriodicalId":33465,"journal":{"name":"Zbirnik naukovikh prats'' Derzhavnogo universitetu infrastrukturi ta tekhnologii seriia Transportni sistemi i tekhnologiyi","volume":"164 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77492161","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A sufficient and economically justified number of logistics transport and customs complexes for processing the imported cargo flow of a given volume has been determined. The study uses methods of systematic and factor analysis of the calculated parameters of cargo processing, taking into account transport, economic and administrative factors of territorial development. It is established that the known methods developed to determine the location of individual transport and logistics centers do not allow to optimize the relevant logistics infrastructure focused on the processing of freight traffic in the transport system of the country. To build an effective solution to the problem of optimal location of several logistics transport and customs complexes, a method for determining the factor-rating potential of urban efficiency for their location in Ukraine, taking into account transport, economic and administrative factors. An assessment of transport work was conducted for 165 settlements of Ukraine, which include cities with a population of more than 30,000 people, as well as settlements with established customs posts or cargo checkpoints across the customs border of Ukraine. For each city, the relative consumption of imported foodstuffs is taken into account. According to the above algorithm, calculations were performed for options that provide for the operation of one to ten logistics transport and customs complexes throughout Ukraine. The analysis of the results of the calculations shows that the volume of transport work is effectively reduced in the case of the creation of 1 to 5 transport and customs logistics complexes. Further increase in the number of logistics transport and customs complexes, and consequently capital investments, does not lead to a significant reduction in total transport work. Accordingly, the factor-rating potential for cities in the zone where the creation of logistics transport and customs complexes is the most rational and has the following values: Dnipro 0.46; Kyiv 0.46; Lviv 0.54; Odesa 0.69; Kharkiv 0.62. The results of the evaluation of the effectiveness of the optimal location of logistics transport and customs complexes can be implemented in the Ukrainian transport system in the construction of logistics infrastructure for the processing of cargo flows of sufficiently large volumes.","PeriodicalId":33465,"journal":{"name":"Zbirnik naukovikh prats'' Derzhavnogo universitetu infrastrukturi ta tekhnologii seriia Transportni sistemi i tekhnologiyi","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46575750","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Requirements concerning the ship's stability and strength are universal for all types of vessels and are postulated in the International Maritime Organization (IMO) codes and documents of the shipping registers of different countries. The cargo operations of bulk carriers are responsible moment, as it determines the level of their seaworthiness and maritime safety at the sea voyage. For bulkers raised strict requirements in regard of cargo distribution and ballast operations with continuous control of their stability and strength. The search of methods for optimal performing cargo operations of the bulk vessels with assurance of all seaworthy parameters at the safe level remains actual. The bulk carriers usually have instructions for their standard loading options provided by the ship's builder, the character of which depends on the specific cargo volume and the number of holds processed at the same time. For each standard variant of cargo operations, the instructions provide a sequence of stages of loading the vessel. At the end of each stage, the vessel must be in acceptable seaworthy condition. In the situation of non-standard loading of bulk carriers, which are not covered by the shipbuilder's instructions, there are difficulties with planning and conducting cargo operations to ensure proper seaworthiness of the vessel, efficient use of its carrying capacity. Ship personnel must independently deal with the distribution of cargo, sorting through various loading options, which is not always efficient and time consuming. At the same time, a number of restrictions on the seaworthiness of the vessel must be met. The purpose of this article is to analyze the possibilities of determining acceptable variants of loading of the bulk vessel, which satisfy the limitations imposed by parameters of the seaworthiness and marine safety. The limitations imposed by the requirements of continuous vessel’s seaworthiness were considered and divided into groups with a view to creating an optimization task. The general approach to formation of a number of permissible loading of the bulk vessel, proposed in the article, creates preconditions for setting the task of choosing the optimal strategy of carrying out cargo operations on the criteria of continuous observance of seaworthy characteristics of the vessel.","PeriodicalId":33465,"journal":{"name":"Zbirnik naukovikh prats'' Derzhavnogo universitetu infrastrukturi ta tekhnologii seriia Transportni sistemi i tekhnologiyi","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45386349","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fast Kurtogram represents the spectral kurtosis value of the signal on the (f, f) plane. The frequency and the frequency resolution are used as the key functions to determine the magnitude of the spectral kurtosis. The best combination makes the kurtosis maximum. During the experimental research the vibration of the rolling bearing of electric motor of electric locomotive ChS7 series was acquired. The broadband spectrum in the frequency range 0 – 9 kHz was extracted and with the help of empiric approach the four frequency bands with resonance excitations were selected. None of four envelope spectra did not have any informative features among numerous random components.

The following research questions emerged: What are the edgy issues of our time, and how do we tackle them? Findings revealed two major trends. First, analysis indicated that the environment/climate change was the most frequently identified topic for teachers' projects, followed by poverty and racism. Second, results indicated that the act of crafting their own SALUs provided the teachers with a sense of control and ownership in how they approached literacy instruction and critical engagement with tough topics, which helped to ease any fears associated with edgy teaching.
