EXPERIMENTS AND USED EVALUATION METRICS USED IN THE DEVELOPMENT OF A LANGUAGE-INDEPENDENT INCREASE DETECTOR
Authors: PRAVORSKA Natalya , HRYPYNSKA Nadiia ,   Khmelnytskyi National University
Published: February 2023

Experiments and evaluation metrics play an important role in the development of a language-independent incremental detector (MRIP), which will allow to analyze the results of the development and the suitability of the developed algorithm and device. The experiments will also provide an answer to the question of evaluating the performance of the developed detector and comparing it with the commercial SIG approach to clone detection, to explore the benefits that the incremental approach can offer. To get an idea of the performance of MNIDP, it is proposed to run it for five software systems (open source), measuring the requirements for time and memory. Also, to answer the question of expanding and improving the initial approach, by using locally sensitive hashing (LCH), there is a need to measure the performance of the proposed expansion on the basis of LCH and compare it with the performance of MNIP. The experiments conducted in the study provided some useful information based on the evaluation of the effectiveness of the proposed expansion on the basis of LCH. More specifically, in some cases, compared to the implementation of MNIDP, the stage of creating an index in the approach based on LCH was two, and in some cases three times slower. A possible reason for this may be the complexity of the MinHash operation, which is a significant part of the overall LCH scheme. This becomes obvious when you consider that the hashing of each tile for each set of tiles during MinHashing must be performed by k-based hash functions. It was assumed that the process of incremental implementation step on the basis of MNIDP will be much slower, due to the calculation of index records on the fly. However, in the course of the study, opposite results were obtained. In practice, this was justified by the fact that the similarity threshold used did not cause a large number of matches between the source files. To gain a better understanding of its behavior, there is a need for further research into the relationship of runtime required for the incremental implementation step flow based on the LCH and the similarity threshold.
RESEARCH OF METHODS OF SEARCHING KEY FRAMES IN VIDEO FLOW WITH THE USE OF NEURAL NETWORKS FOR SEARCH SYSTEMS
Authors: MELNYKOVA Nataliia , POBEREIKO Petro ,   Lviv Polytechnic National University
Published: February 2023

The paper presents a comparative analysis of current research in the field of data analysis in the format of video content and regarding it, that effective methods of analysis of these data are methods of search keyframes in the video stream. The analysis shows that the application of a method of processing visual data is determined by the structure of this data. Therefore, in order to simplify their analysis, they were divided into the following categories: consistent comparison; global comparison, based on clustering, and those that use events or objects. Especially valuable are the methods of comparing and matching matches (fragments), namely: methods of sequence search (detection of objects or certain actions on frames); methods of classifications (determining the content of personnel and their distribution to certain categories); frame decoding methods (description of the characteristics of a particular image) and methods for detecting anomalies in the video stream (search for objects, characters that are unique properties of the fragment relative to others). It shows that the most optimal of the considered methods there are methods that are based on technologies of artificial intelligence and machine learning. And also shows the difference and efficiency of deep learning methods in relation to сonventional methods. Particularly promising are the methods, the implementation of which is to model the temporal dependences of the variable range using convolutional neural networks and functions with special attention mechanisms. Methods that use an Actor-Critic model embedded in a Generative adversarial network have also demonstrated their effectiveness. It is shown that the development of these methods contributes to the rapid development of information systems with which you can successfully analyze video content and recognize its origin.
FEATURES OF MODERN WEB APPLICATION TESTING
Authors: BAHRІI Ruslan , PETROVSKYI Serhii ,   Khmelnytskyi National University
Published: February 2023

This paper investigates the technology and approaches to testing web applications in modern frameworks. The main techniques of manual testing, which require a large amount of manual work, are considered. The disadvantages of implementing the black-box testing method include the development of a formal specification, and the application of the white-box testing method requires analysis of software code. Particular attention is given to automated testing technologies, which are proposed to be used to develop sites in modern frameworks. The Test pyramid and test levels are described in detail, and the main advantages and disadvantages of each level are analyzed. At the first level, a set of tests consists of unit tests that verify that an individual unit is working correctly according to the requirements of the specification. At the second level of the automation pyramid – integration tests check the interaction of a fragment of code with external components. At the third level – end-to-end tests perform testing of various user scenarios, and UI tests check the correct operation of the web application interface. It is proposed to use behavioral development technology (BDD) for automated testing of web applications. BDD focuses on studying problems formulated based on customer stories and the construction of logic and tests based on these problems. BDD tests are best worked for integration testing, which involves testing different user scenarios. A dependency injection (DI) design template has been used to improve the efficiency of the web application development process, with tools built into modern frameworks. This template applies the transfer of dependencies to an external, specially designed software component. Dependence is injected using a special IoC container.
RESTORATION OF PARTS OF AGRICULTURAL MACHINES WITH ZINC-BASED GALVANIC COATINGS
Authors:   Vinnytsia National Agrarian University, BRATSLAVETS Bogdan
Published: February 2023

Galvanizing is most often used to protect against corrosion. In repair production zinc coverings are used for protection against corrosion of fastening details and restoration of landing surfaces of lightly loaded details. Electroplating is the process of applying metal to the surface of parts by crystallizing it from an aqueous solution of the corresponding salts (electrolyte) when a direct current passes through them. An electrical circuit is closed by an electrolyte between two conductors called electrodes. The electrode to which the conductor of the external circuit with a plus is attached is called the anode, and with a minus – the cathode. The repaired part, on which the metal is built up, serves as the cathode, and the anode – plates, copper, lead, zinc, cadmium and other metals. In electrolysis, soluble and insoluble anodes are used. In practice, soluble lead is most often used, and insoluble lead is used only for chromium plating. The preparation of the surface of the part before coating (machining, degreasing, digestion) is important for the quality of the coating. The paper identifies the advantages and disadvantages of the method of updating parts of agricultural machinery with galvinic coatings based on zinc. This makes it possible to analyze the results of experiments and evaluate the effectiveness of using this method of restoring parts. The article presents the technological process of restoration of parts by galvinic galvanizing using an activator and the results of experiments using graphs of the dependence of the rate of coating on the current density and the speed of the activator. Determine whether the use of an experimental activator will increase the speed and quality of coating on parts.

Introducción: las lesiones en el deporte son frecuentes, especialmente, en los atletas profesionales y las consecuencias son importantes, a nivel físico, psicológico y social. Se han señalado algunas variables psicológicas, como factores que pueden influir en la probabilidad de sufrir una lesión, entre ellos, el estado de ánimo y la sintomatología depresiva; sin embargo, en estudios previos, se han reportado datos contradictorios y apenas se han realizado investigaciones de este tipo, en México. Objetivo general: investigar las posibles diferencias en la sintomatología depresiva y estados de ánimo entre futbolistas adolescentes que presentan lesión respecto a los ilesos, en el periodo de tiempo del 2010-2016. Materiales y Métodos: para evaluar los aspectos mencionados existen diferentes pruebas psicológicas, en este caso, se utilizó, el Perfil de Estados de Ánimo, POMS (por sus siglas en inglés, Profile of Mood States), en la versión castellana y La Escala Autoaplicada de Depresión de Zung (Self-Rating Depression Scale, SDS). La muestra estuvo formada por 24 varones, con edades entre 14 y 19 años, pertenecientes al Monarcas TZEFORT- Zacapu, de la tercera división, 12 lesionados y 12, sin lesión. Resultados y discusión: no se observan diferencias estadísticamente significativas en la sintomatología depresiva, ni tampoco en ningún estado emocional. Conclusión: la sintomatología depresiva y los estados de ánimo no se relacionan con el riesgo de lesión en futbolistas adolescentes.

This article discusses the difference between indirect intent (dolus eventualis) and unintentionality. It is stated that the difference is found not only in the substance of the so-called volitional element of the mens rea of an offence, but also in the substance of the so-called intellectual element. With the help of findings from the area of epistemic logic, it is demonstrated that the difference between the intention to commit an offence and its commission in the form of knowledgeable unintentionality arises from the fact that in the latter case the perpetrator thinks he/she will avoid committing an offence. Considering the above, the authors formulate the relevant proposals of amendment to the provision of the Polish Criminal Code which defines unintentional commission of an offence. The aforementioned analysis was based on an assessment of grounds for judgments in cases involving manslaughter and affray or battery resulting in death.
Wybrane aspekty tajemnicy w postępowaniu z udziałem nieletniego

This article contains an analysis of selected aspects of secrecy in proceedings with the participation of minors. The analysis of selected legal institutions in the context of secrecy – which is the essence of this article – is preceded by an attempt at explaining the notion of secrecy, including professional secrecy, in the context of proceedings with the participation of minors. It would seem that identifying the elements that make up the essence of secrecy should not cause much trouble: everyone has at some point revealed his/her secret to another person or has been entrusted with one. Nevertheless it is not easy to define this concept in a precise and non-arbitrary way. The situation becomes even more complicated when the secret has anything to do with the law, because even though the legislator defines professional secrecy in several statutes, these definitions do not mention the obligation of confidentiality as such, being limited to determining the scope of such obligation. After the analysis of the definition of secrecy, including professional secrecy, beginning with the dictionary definition and ending with the author’s attempt at formulating her own definition of professional secrecy, the remaining part of the article is devoted to selected aspects of secrecy in criminal proceedings with the participation of a minor, that is, closing the hearing with the participation of a minor to the public and opinions of experts about minors in the context of professional secrecy.
Research on the uncertainty of low-carbon environmental governance system and its impact on the dual goals of carbon emission reduction
Authors: Zhang Xiufan
Published: February 2023

Based on the theoretical analysis of different dimensions of China's low-carbon governance environment, the uncertainty index of the low-carbon governance environment is constructed, and the fuzzy comprehensive evaluation of China's low-carbon governance environment is carried out based on the improved analytic hierarchy process and an entropy weight method. The dynamic panel model and PSTR transfer model are established to divide the degree of environmental uncertainty in low-carbon governance and to explore the regional heterogeneity impact of environmental uncertainty on the dual goals of carbon emission reduction. The empirical results show that as the uncertainty of the low-carbon governance environment changes from a low-zone system to a high-zone system, its negative impact on the realization of the dual goal of carbon emission reduction is gradually strengthened. The uncertainty of low-carbon governance environment will hinder the realization of China's carbon emission reduction targets. Stable low-carbon policy environment and economic environment are conducive to promoting carbon emission reduction targets from environmental governance, while the stability of technological innovation environment and carbon trading mechanism is an important factor in promoting carbon emission reduction targets.
Digitalization, Emerging Technologies, and Financial Stability: Challenges and Opportunities for the Indonesian Banking Sector and Beyond. Muyanja Ssenyonga Jameaba

Published: February 2023

One of the challenges financial institutions is how to adapt to a changing business environment, increasingly demanding and differentiated customer preferences, digitalization and technological change. Using a documentary analysis approach, the article navigates the ramifications of API based open banking, Block Chain Technology (BCT) and entrance of Fintechs, Big technology companies (Big Tech1) and Telecommunications companies (Telcos on the performance of general banking sector and financial system stability. Results underscore the role of digitalization revolution and ICT in fundamentally changing the financial service development and delivery, by empowering ICT savvy non-financial institutions including financial technology companies (Fintechs), TELCOS, and Big Tech to become players in the industry; enhancement of financial inclusion thanks; reduction in transaction costs; and inducing traditional banks to adopt new business models that leverage Big Data and data analytics approach. Digitalization has paved way for the development of agile, adaptive open banking supporting business models financial that supported collaboration with other providers of financial services, back end and front end technologies, diversified customer base, strengthened capacity and capabilities to leverage customer experience, develop and deploy financial innovations to strengthen competitiveness. Nonetheless, despite its many benefits, most banks are yet to adopt BCT due to persisting uncertainty that surrounds the technology a, its adoption, deployment and operations. BCT adoption has been undermined by an array of failures of several BCT based crypto exchanges and assets, limited understanding of BCT business case, regulatory ambiguity, and risk aversion. The adoption of BCT promises improvement in the integrity and authenticity of financial service delivery, reduction in vulnerability to cyber insecurity, decentralized authentication, increased operational efficiency, low compliance cost, shorter onboarding of new product offers and customers, accelerated development and deployment of new product offers, which should diversify and broaden liability sources and investment portfolios. Failure to adopt and deploy both business processes and products on BCT poses the danger of empowering new entrants into financial service development and delivery. The reluctance of conventional banks to adopt emerging technologies poses threat to both their interest and non-interest income sources, ability to provide monetary policy transmission function, providing customer wealth custodianship services, serving financial payments and money supply transmission functions, and serving as lynchpin in financial system liquidity. The article highlights challenges and pathways to mitigating them in such a manner that improves bank performance without undermining financial system stability.
For the Reich and the Europe of Nations! The “New” NPD as a Paragon and Cooperation Partner of the Czech Exreme Right
Authors: Prokůpková Vendula
Published: February 2023

This paper deals with the transnational cooperation of the Czech and German extreme right. The paper focuses on one of the most prominent international partners of the Czech extreme right – the German Nationaldemokratische Partei Deutschlands. By adopting the discourse analytical framework of the Essex School, the author focuses on revealing the discursive conditions as conditions of possibility within which the cooperation between the NPD and the Czech extreme right has gradually formed over the last 25 years (1996-2021). The author of the text first briefly summarises the NPD’s history and explores the development of the party’s foreign policy conception since the second half of the 1990s, when the party became radicalized and opened itself up to a cooperation with the neo-Nazi movement. Further, reflecting on the changes in the NPD’s political discourse, the author explores the discursive conditions of various stages of the NPD’s cooperation with the Czech extreme right.

A greenhouse has one purpose: to provide and maintain the environment that will result in optimum crop production for maximum profit. This includes an environment for work efficiency as well as for crop growth. This publication is limited to describing equipment and methods used to control or maintain desirable temperature in a greenhouse during those periods when supplemental heat is required. There are many ways this can be accomplished from the standpoint of equipment used, type of fuel and construction used, and management practices followed. Because each operation usually has some unique characteristics, such as types of plants produced, level of desired production quality, type(s) of greenhouse(s) used, and management procedures followed, it is important that all of these factors be considered when selecting and installing a heating system. This 5-page fact sheet is a minor revision written by J.

Reclaimed water plays a significant role in water conservation, a goal of every Florida-Friendly Landscape. However, using reclaimed water on plants harvested and consumed from the home landscape must be approached with caution for vegetables, fruit trees, herbs, and other edible crops due to the risk of contamination from pathogens and salts. Before using reclaimed water in your Florida-Friendly edible garden, it is important to have a clear understanding of what it is and how it can be safely used. The target audience for this new 4-page publication of the UF/IFAS Environmental Horticulture Department is Florida residents who irrigate landscapes, including edibles, with reclaimed water.

Handling COVID-19: Produce Farms and Packinghouses
Authors: Dunn Laurel , Danyluk Michelle
Published: February 2023

While there is no evidence that the COVID-19 virus is a food safety concern, it is a worker health concern because it spreads via close person-to-person contact or by contact with contaminated surfaces. Food does not appear to be a likely cause of COVID-19 transmission, but many of the same practices used to prevent foodborne illness on foods should still be used to reduce the likelihood of COVID-19 contamination on fresh produce and the risk of COVID-19 spread among farm and packinghouse workers.

Authors: Seymour Natalie , Yavelak Mary , Christian Candice , Chapman Ben , Duvalsaint Emmanuel , Danyluk Michelle
Published: February 2023

Daprè CDC, yon metòd efikas pou kwape pwopagasyon maladi enfektye sa a se lè w kouvri visaj ou ak yon twal oswa w mete yon mas an twal. Yo itilize mas an twal yo pou kouvri bouch ak nen yon moun ki enfekte oswa ki ta ka enfekte si l pran viris la lè yon moun ap touse, estènen oswa nan yon konvèsasyon nòmal. Mas an twal yo bay bon jan pwoteksyon si yo 1) bon kalite 2) mete yo byen 3) sèvi ak yo byen. Lè w mete yon mas an twal, li ka diminye risk men li pa bay yon pwoteksyon total kapital. Nou dwe swiv lòt metòd pou diminye risk yo tankou: pa rete pre yonn ak lòt, lave men nou, itilize sanitayzè/dezenfektan pou men epi evite manyen je w, nen w ak bouch ou.
