O. Gorobсhenko

The article is devoted to the problem of implementation of intelligent control systems in transport. An important task is to assess the information parameters of the control systems. In the existing works the question of definition of one of the basic parameters of functioning of locomotive control systems - information value of separate signs of a train situation is not considered. This does not make it possible to determine the order of signal processing at the input and assess their contribution to the adoption of a control decision. Moreover, informativeness is a relative value, which is expressed in the different information value of a particular feature for the classification of different train situations. Also, the informativeness of the feature may depend on the type of decisive rules in the classification procedure. The quality of recognition of a train situation in which the locomotive crew is, depends on the quality of the features used by the classification system. The decisive criterion for the informativeness of the features in the problem of pattern recognition is the magnitude of losses from errors. To determine the range of the most informative features of train situations, the method of random search with adaptation was used. The results of the work make it possible to optimize the operation of automated and intelligent train control systems by reducing the amount of calculations and simplifying their algorithm.

Flowers, ornamental plants, planting material (saplings) and other plants with regard to which the market with possibility of carrying out independent adequate marketing was formed, are the subject of evaluation by the experts in field of forensic merchandising. With the development of the market and market relations such goods as flowers, planting material and others are increasingly encashed in the market of Ukraine and become the objects of forensic merchandising examinations and expert researches. Special feature of merchandising researches of the plant origin objects is the use of the comprehensive approach to the estimation of their quality and cost. Researches are carried out with the purpose of determination of properties, consumer value, conformity to standards and specifications of plants certain kinds. When studying a considerable variety of flower plants, one distinguishes scientific and industrial classifications. In merchandising flowers industrial classification of flower ornamental plants which provides distribution of flower plants to the separate groups similar on biological properties, the agricultural technician of cultivation and practical application in gardening is used. During carrying out merchandising examinations on an establishment of consumer properties of certain kinds plants, namely establishments organoleptic indicators of quality and quantity of flower decorative production given for research, the expert checks conformity of this production to requirements of normative and technical documents. Requirements to quality of flower production are normalised by standards depending on production kind – cutf lowers, pottery blossoming plants, pottery decorative sheet plants, sprouts of flower decorative production, planting material, seeds of flower ornamental plants. At carrying out merchandising researches of flower decorative production, plants and saplings it’s necessary for merchandising experts to pay special attention on definition of quality indicators and a grade of plants according to standards, and also to consider data concerning age of a plant, novelty of a grade and origin country of production.

Abstract Background Cutaneous neurofibromas (cNFs) are the most common tumors in people with neurofibromatosis type 1 (NF1) and are associated with reduced quality of life. There is currently no widely accepted standardized language for describing cNFs clinically or histopathologically. The objective of this study was to evaluate interobserver agreement across pathologists in describing and reporting of neurofibromas involving the skin. Methods Twenty-eight (H&E)-stained slides of cNF were scanned using an Aperio XT scanner. The digital images were reviewed by 6 pathologists, who entered free text of up to a 200 word description for each case into a REDcap database. Responses were analyzed for the most commonly used terms based on frequency, as well as agreement (reported as concordance) between reviewers. Results A set of the terms most commonly used by pathologists for the histological classification of cNF along with areas of agreement and disagreement have been identified. The study shows that there was strong agreement across reviewers that not all neurofibromas involving the skin are cutaneous neurofibromas and regarding the presence or absence of atypical features and heterologous elements. Areas of less concordance were identified and include cNF subtypes, definition of extension and pattern of growth, as well as the distinction of a cNF from a plexiform without an intraneural component involving skin. Conclusions This work is the first step towards development of a robust classification system and devising “gold standard” histopathologic diagnostic criteria for cutaneous neurofibromas.

Design is one of the most popular instruments for administration of policy in different fields and spheres. This is reinforced by creation, implementation, and support of numerous political projects of the local, regional, national, and global levels. At the same time, design and fulfillment of various political projects is complicated by the absence of sound understanding of the content and main approaches towards the key concept of project activity — “political design”. The modern social-humanistic scientific literature has formed explicit approaches towards understanding the stages of political design, the actors of project activity in the political sphere, resources of political design, criteria for the effective implementation of political projects, classification of political projects. However, the very concept of “political design” remains polemical. Its content is saturated with different meanings, which subsequently complicates the study of other aspects and vectors of project activity in the political sphere. This article aims to summarize the main approaches towards elucidation of the concept of “political design”, outline its key parameters, and formulate the relevant definition. Methodological framework for this article is comprised of the theoretical principles of the project approach towards interpretation of politics. The author provides the original definition of the concept of “political design”, systematizes the main approaches towards explanation of its structure and content, offers the socio-technological assessment of the key parameters of modern political projects, and develops additional grounds for their classification. The article identifies and compares the procedural, administrative, pragmatic, organizational, sociocultural, historical, and innovative models of project activity in politics, describes their heuristic capabilities and conceptual boundaries. The author also develops the criteria for assessing the quality of project activities in politics, and correlates them with the basic models of modern political design.

The purpose of this paper is to analyze, discuss, and develop a study of world universal digitalization processes as well as challenges and threats, and develop an approach to defining the shadow digital economy. Along with huge innovative achievements, digitalization processes are accompanied by the formation of a digital economy and the growth of illegal activities. Digital economy implies total globalization, creates an ultra-high competitive environment, provides a new quality of life, business, and public services. At the same time, many traditional areas of activity are being destroyed. In addition to understandable achievements, it is necessary to analyze new obvious and hidden threats that digitalization processes carry. The analysis shows the causes and factors of the emergence and functioning of the new segment in the shadow economy. The approaches to the definition of this category and its content are discussed. A classification of criminal-oriented products and services that are the basis of a highly profitable illegal business has been proposed. The problem of confrontation with Shadow Digital Economics acquires particular urgency in the face of the emergence of new overt and hidden threats to the individuals, society, and the state. The main components of the digitalization process are analyzed. Conclusions are drawn about the development of shadow digitalization processes and the formation of a shadow digital economy, which is directly related to cybersecurity.

Abstract Definition of a composite [1] describes an ideal composite material with perfect structure. In real composite materials, structure is usually imperfect - composites contain various types of defects [2, 3-5], especially as the casted composites are of concern. The reason for this is a specific structure of castings, related to course of the manufacturing process. In case of metal matrix composite castings, especially regarding these manufactured by saturation, there is no classification of these defects [2, 4]. Classification of defects in castings of classic materials (cast iron, cast steel, non-ferrous alloys) is insufficient and requires completion of specific defects of mentioned materials. This problem (noted during manufacturing metal matrix composite castings with saturated reinforcement in Institute of Basic Technical Sciences of Maritime University Szczecin) has become a reason of starting work aimed at creating such classification. As a result, this paper was prepared. It can contribute to improvement of quality of studied materials and, as a consequence, improve the environment protection level.
