Statistical Analysis of the Activity of the Thematic Content on the Internet for Predicting the Development of Information Threats

У статті наведено результати статистичного аналізу активності тематичного контенту в мережі Інтернет на сегменті реальних експериментальних даних інформаційних повідомлень. Проведений аналіз довів можливість розгляду частоти появи тематичного контенту, як монотонного міандрового процесу з адитивною випадковою складовою Результати аналізу забезпечили визначення виду залежності частоти появи тематичного контенту від часу, закону розподілу випадкової складової та отримати його статистичні характеристики. Отримані результати доцільно застосовувати на етапі прогнозування розвитку інформаційних загроз. Результати статистичного аналізу показали, що частота активності тематичного контенту в мережі Інтернет має нелінійний характер, є випадковим стаціонарним процесом з явно вираженим зростаючим або спадаючим міандровим трендом.The article presents the results of the statistical analysis of the thematic content of the Internet in the segment of real experimental data of information messages. The analysis proved the possibility of considering the frequency of appearance of thematic content as a monotone meander process with an additive random component. The results of the analysis provided the definition of the type of dependence of the frequency of thematic content occurrence from time, the law of the distribution and of the random component, and obtain its statistical characteristics. The obtained results should be used at the stage of forecasting the development of information threats. The results of the statistical analysis showed that the thematic content frequency on the Internet is nonlinear, is a random stationary process with a clearly pronounced rising or declining meander trend

The article describes the features of optimizing the flight path of an unmanned aerial vehicle. The paper analyzes the composition and designation of main equipment and payload of unmanned aerial vehicle. In particular, attention is drawn to the basic requirements that relate to the unmanned aerial vehicle today.У статті проведено характеристику особливостей оптимізації траєкторії польоту безпілотного літального апарату. У роботі здійснено аналіз складу та призначення основного обладнання і корисного навантаження безпілотного літального апарату. Зокрема, звертається увага на основні вимоги, які сьогодні ставляться до безпілотного літального апарату

Management Matters

New indications of managerial innovations are created and then used to show that changes in organizational technologies are an important source of economic growth. Specifically, the analysis demonstrates that, first, in response to a positive managerial technology shock, output, productivity and hours significantly increase in the short run, second, these types of innovations are as important as non-managerial ones in explaining movements in these variables at business cycle frequencies, and, third, product and process innovations promote the development of new managerial techniques.Business Cycles; Productivity; Management techniques; Technical Change

Improving supply chain efficiency through simulations - Literature and methodological review

Increased competition, efficiency and profit orientation largely determine the operation of today’s companies. While the XX. In the twentieth century, the emphasis was on mass production, large batch numbers, and economies of scale, until today, consumer demand has shifted significantly toward individualized products and services. The consumer expects almost perfect quality, reasonable price and immediately available stocks. That is why it is necessary to tailor the supply chain to the needs of consumers as perfectly as possible. Every small change in the way a company operates can have different effects that managers need to respond to immediately. In a company where there is some flow of auxiliary fuels, semi-finished or finished products, the proper design of the supply chain is a focal point that largely determines its operation and efficiency, as logistics costs significantly affect the consumer prices of products and services. The solid foundation of my topic is provided by the logistics knowledge and the supply chain management that extends it, which already examines the entire supply chain instead of one player at a time. A XXI. The development of information and IT in the 21st century makes it possible to apply new approaches in this field as well and to develop an approach in which we do not assess the effects of changes in retrospect, but prepare for them in advance. In my research work, the optimization of logistics activities through simulation is the focus. The simulation has been an integral part of technical sports and engineering work for many years, this methodology is not yet used in the field of supply chain management, which would provide an opportunity to analyze the effects of changes without risk and would be a tool for companies to model and measure their activities. And measurability would provide an opportunity for correction and improvement, which plays an essential role in increasing efficiency and effectiveness. Based on this line of reasoning, I believe that the combination of supply chain management and simulation holds untapped potentials. In my article, I will review the currently known and useful simulation methodologies, which shows the processing of the issue and the prevalence of the methodologies

Volumes of Evidence - Examining Technical Change Last Century Through a New Lens

Although technical change is central in much of modern economics, traditional measures of it are, for a number of reasons, flawed. We discuss in this paper new indicators based on data drawn from the MARC records of the Library of Congress on the number of new technology titles in various fields published in the United States over the course of the last century. These indicators, we argue, overcome many of the shortcomings associated with patents, research and development expenditures, innovation counts, and productivity figures. We find, among other things, the following: the pattern and nature of technical change described by our indicators is, on the whole, consistent with that of other measures; they represent innovation not diffusion; a strong causal relationship between our indicators and changes in TFP and output per capita; innovations in some sub-groups have had a greater impact on output and productivity than others and, moreover, the key players have changed over time. Our indicators can be used to shed light on number of important issues including the empirical relationship between technology shocks and employment, the role of technology in cross-country productivity differences, and the part played by technological change in growing skills premia in the U.S. during the last few decades.Business Cycles, Technical change, productivity, measurement

Read All About it!! What happens following a technology shock?

Existing indicators of technical change are plagued by shortcomings. I present here new measures based on books published in the field of technology that resolve many of these problems and use them to identify the impact of technology shocks on economic activity. They are positively linked to changes in R&D and scientific knowledge and capture the new technologies' commercialization dates. Changes in information technology are found to be important sources of economic fluctuations in the post-WWII period and total factor productivity, investment and, to a lesser extent, labor are all shown to increase following a positive technology shock.business cycles, technical change, information technologies
