The purpose of the paper is to analyze the positioning of Ukraine in the global indices of innovative development and competitiveness, to evaluate the indicators of innovation activity and, based on the outcomes of the research, to determine the place of Ukraine in the global innovation space. The dynamics of innovation activity on an international scale based on the consolidated indicators of the Global Innovation Index are presented. Ukraine’s position in it and progress in achieving goals to better understand the processes that stimulate or constrain innovation are determined. Econometric methods to generalize the positioning of Ukraine in the global innovation space and the DEA method to study the relative individual effectiveness of the innovation environment and innovation activities in Europe are used.

The realization of digitalization in production companies – currently also referred to as Industry

4.0 – aims for reduction of internal value creation costs as well as costs for intercompany

collaboration and plays a key role in their current strategy development. However, related

strategy research still lacks to provide operationalized digitalization methods and tools to

practitioners with scientific rigor as well as real-world relevance. To challenge this status

quo, we present a scientifically grounded 14-step procedure model including 11 practically

tested tools, developed specifically for real-world application. The model leads practitioners

from their first contact with industrial digitalization, through the maturity assessment of

143 digitalization items, until the implementation of a KPI-monitoring system and a continuous

improvement process. We applied and re-worked the procedure model during three

years of application. Validation and Feedback from practitioners and scholars indicate, that

the model drives strategy development towards objective and data-based decision making

and increases stakeholder engagement in organizations considerably.

The spread of digital technologies dramatically changes production processes. The fourth

industrial revolution opens up new opportunities for the introduction of technologies, having

a significant impact on the production cycle, starting with highly automated production lines

and ending with the large-scale implementation of technological solutions designed to improve

productivity, optimize costs, quality and reliability. Defining digital transformations,

primarily in the manufacturing industry, as a strategic imperative for the entire economy

based on opinions and intentions of entrepreneurs (short and medium-term), key aspects of

the digitalization process in Russian medium, high-tech and low-tech manufacturing industries

are revealed. A set of tendencies in the development of digital technologies by their main

types is presented, the level of industry participation in digital transformation is shown, as

well as many other important digital transformation processes in enterprises that are not

measured by quantitative statistics.

Dr. Maciej Maryl, Head of the Digital Humanities Center and Deputy Director at the Institute of Literary Research, Polish Academy of Sciences, talks about the table where innovations are born, the limits of literariness, and Polish humanities projects that can conquer the world.

In this article, the author will try to conditionally transform the energy capacities of NNEGC

Energoatom by converting a liability into an asset using the example of bitcoin. With a surplus of

nuclear power generation, one of the modern tools for using excess electricity is directing it to cryptocurrency

mining. The author of the article will try to calculate the possibilities of Ukrainian NPPs

in the cryptoindustry market by analyzing the competitiveness, market trends and the approximate

profitability of this kind of activity. The essence of the article lies in the intervention of the state

energy giant in completely new activities, partial monopolization of the market and interference

in the activities of decentralized cryptocurrencies, as well as the very novelty of combining two

different fields of activity and the global nature of the consequences. Mining can be used to convert

the underdeveloped electricity or all of Energoatom’s capacities totally, but at the same time it can

also affect the cryptoasset market in the field of decentralization, as the primary cost factor to affect

the price of assets and allow for obtaining super-profits at a state enterprise. The author of the article

tries to understand the profitability of such actions and, in general, to understand the globality

of the idea. The results of the entry of the national energy giant into the cryptoasset market will

change the global processes in the ecosystem of the cryptoindustry and change the situation both

on the electricity market in the region and, in general, will affect the processes of globalization and

unification of the financial sectors of the economy.

Since the dawn of the millennium, we have been regularly functioning in two parallel realities at the same time: ”meatspace” and ”cyberspace.”

In digital revolution, the appropriate IT infrastructure, technological knowledge are essential for the success of companies, where the success of the digital transformation depends on digital maturity. The aim of the study is to define the digital maturity, theoretical foundation of the digital maturity model and present a framework for small and medium-sized enterprises (SMEs) understanding where they are in digitalisation (how advanced their digital resource system and digital approach) to respond faster and efficiently to environmental changes. The model construction is based on theory of dynamic capabilities, graduation models, and SMEs management challenges. The model is a dynamic model to support management in strategic, digital and organizational developments, which is divided into IT and organizational dimensions, including 6 components and 28 subcomponents. The ultimate goal of the study is to determine the component weights to create a neurofuzzy model.

The article features a systemic approach to digitalization in mining, covering the production process, supervision and management. Business continuity management of a critical infrastructure was characterized with respect to an industrial facility, i.e. a mine. The “SILESIA” Integrated Security System was described. This solution, offered by CNP EMAG, is an example of a systemic approach successfully implemented in industry. The article includes information about the development of technological hardware solutions as well as software which is able to assess the solutions developed in the SecLab Information Security Technology Development Laboratory in the EMAG Institute.

This paper points out assumptions and reasons for using digital technologies, the importance of using digital technologies in teaching and management. It also refers to the digital technologies and digital competences as an essential part of the competency model of a teaching staff in education. It also points out the fact that existing competency models need to be further explored, decomposed, and formulated as an illustration by the digital competences extensions.

In this paper we show how formal computer science concepts—such as encoding, algorithm or computability—can be interpreted philosophically, including ontologically and epistemologically. Such interpretations lead to questions and problems, the working solutions of which constitute some form of pre-philosophical worldview. In this work we focus on questions inspired by the IT distinction between digitality and analogicity, which has its mathematical origin in the mathematical distinction between discreteness and continuity. These include the following questions: 1) Is the deep structure of physical reality digital or analog, 2) does the human mind resemble a more digital or analog computational system, 3) does the answer to the second question give us a cognitively fruitful insight into the cognitive limitations of the mind? As a particularly important basis for the above questions, we consider the fact that the computational power (i.e., the range of solvable problems) of some types of analog computations is greater than that of digital computations.

The paper presents the long-term project “Online Dictionary of Surnames in Germany” (“Digitales Familiennamenwörterbuch, DFD”), its conception, main objectives, and its technical realisation. By means of representative examples, the paper depicts how the project works along the categories of conflation, validation, specification or revision of etymologies so far proposed in standard references and the development of new ones. Exploiting new digital resources — especially with the help of new findings in surname geography, the surname stock can be captured and analysed all-encompassing and systematically.

Surnames of foreign origin like English, French, Italian, Slavic, Baltic or Turkish are also considered. The importance of Slavic roots in German surnames is exemplified by the name Novak (‛new settler’) which ranks position 156 in the total frequency of German surnames. The article’s outlook discusses the importance and possibilities for future cooperation with surname projects in other countries like Poland, with a long-term perspective for a European network of surname dictionaries.

In this text the author reflects on the semiotic existence of culture discourses in connection with the rapid development of digital technology. The author analyzes selected texts of digital art as examples of the transformation in how works of literature, sculpture, or film exist. The article covers how movable font, which changes in shape and color, participates in shaping literary meanings; the creation of semiotic and interactive figures; the textualization of the user’s actions and body; dematerialization; processuality; narrativization; the temporalizing of sculpture which changes before the eyes of the recipient; the presence of alternative narratives in literature and film; multi-variant plots co-created by the recipient; and the artistic use of other discourses. The author proves that the structure and specificity of the digital sign lies at the base of the changes. The digital sign is immaterial, programmable, and hybrid, and combines aspects of expression, meaning, and action, which makes it efficient.

This paper investigates the terrain-aliasing effects on geoid determination using different gravimetric reduction schemes. The high resolution of digital terrain model (DTM), if available, should be used for every gravimetric reduction scheme since it can precisely map the details of the terrain. The reduction methods used in this study are the Rudzki inversion method, Helmert's second method of condensation, the residual terrain model (RTM) method, and the Pratt-Hayford (PH) topographic-isostatic reduction technique. The effect of using different DTM grid resolutions of 6", 15", 30", 45", I' and 2' on gravity anomalies and absolute geoid undulations is studied for each of these reduction schemes. A rugged area in the Canadian Rockies bounded by latitude between 49°N and 54°N and longitude between 236°E and 246°E is selected to conduct numerical tests. Our results suggest that a DTM grid resolution of 6" or higher is required for precise geoid determination with an accuracy of a decimetre or higher for any gravimetric reduction method chosen to treat the topographical masses above the geoid in rugged areas. The most precise geoid models obtained in this test are the ones obtained using Rudzki, Helmert, and RTM methods with 6" DTM resolution.

The paper presents estimation of positional accuracy of digital maps using statistical analysis. Investigations have been performed for four large-scale digital maps made using different methods of producing digital map data: new total station survey (object A), re-calculation of previous direct measurements (orthogonal and polar surveys) (object B), manual vectorisation of a raster orthophotomap image (object C) and graphical-and-digital processing of analogue maps (object D). Analysis has been performed for large statistical samples of sets of vectors of shift t: L of control points and their components, i.e. true errors t: x, t: r of increments of co-ordinates. In the case of a map produced by means of new survey with an electronic tacheometer, the true errors were represented by differences between co-ordinates of control points obtained from two separate set outs. In the case of other methods of data collection for digital map production true errors were represented by differences of co-ordinates acquired from an investigated map and co-ordinates calculated from new direct surveys.

Nowadays, many known celebrities use social media as a channel to promote positive narratives and support humanitarian work. This article offers an analysis of the argumentative strategies employed in Instagram by a Spanish actor Javier Bardem, an Antarctic ambassador for Greenpeace, in order to attract the attention of the public to the ecological problems of the Antarctic Ocean. I have studied 76 posts published in Instagram during the 2018-2019 period. Starting from the theoretical framework of argumentation, as well as of pragmatic linguistics, I analyze those linguistic mechanisms and discursive strategies that are used with the aim to achieve the persuasive purposes.

A vocal tract model based on a digital waveguide is presented in which the vocal tract has been decomposed into uniform cylindrical segments of variable lengths. We present a model for the real-time numerical solution of the digital waveguide equations in a uniform tube with the temporally varying cross section. In the current work, the uniform cylindrical segments of the vocal tract may have their different lengths, the time taken by the sound wave to propagate through a cylindrical segment in an axial direction may not be an integer multiple of each other. In such a case, the delay in an axial direction is necessarily a fractional delay. For the approximation of fractional-delay filters, Lagrange interpolation is used in the current model. Variable length of the individual segment of the vocal tract enables the model to produce realistic results. These results are validated with accurate benchmark model. The proposed model has been devised to elongate or shorten any arbitrary cylindrical segment by a suitable scaling factor. This model has a single algorithm and there is no need to make section of segments for elongation or shortening of the intermediate segments. The proposed model is about 23% more efficient than the previous model.

Kamil Śliwowski of the Information Society Development Foundation explains how the current reach and scale of the Internet entail a new stage of civilization – irrespective of what technologies ultimately gain the widest popularity.

Commonly known DC-AC switching converters are commonly used in compensator branches. One example of this is a static synchronous compensator (STATCOM). It consists of a voltage source converter (VSC) and acts as an inverter with a capacitor as a DC power source. These compensators use the PWM switching scheme or space vector modulation (SVM) method. Both methods require the desired signal to be generated. In some cases, as during the synthesis of self-excited systems or active energy-compensators, it is necessary to perform the desired branch immittance, e.g. negative capacitance, inductance, resistance or irrational impedance. In such cases, it is necessary to control the universal branch on the basis of a formula. This article presents the implementation method for the convolutional type impedance operators.

Development of a reliable numerical model capturing major physical mechanisms controlling explosive welding and considering properties of all process components i.e. base plate and flyer plate is the goal of the paper. To properly replicate materials behavior under these severe conditions a meshfree approach, namely Smooth Particle Hydrodynamics (SPH), was used to discretize the computational domain. The model is based on the Mie-Gruneisen shock equation of state applied to the Ti/Cu system as a case study. Examples of results in the form of velocity, equivalent stress, equivalent strain, and pressure fields are presented within the paper.

This paper aims to improve understanding of the drivers and barriers to digital transformation in asset management. Accordingly, this paper contributes to the literature by conducting a qualitative Delphi study with 15 experts (including academia, consultancy and industry) to identify, validate, and classify the drivers and barriers affecting digital transformation in asset management. As a result of the experts’ interactions, 20 barriers were identified. The main barriers to digital transformation in asset management are the following: Misunderstanding of the strategic importance of asset management, no clear vision/strategy, existing mindset and culture, inadequate asset management system, lack of understanding of digital trends, and lack of employee knowledge and skills. The study also highlights 12 drivers that are critical to the digital transformation of asset management. These include cost reductions, opportunities in condition monitoring of assets, expected benefits in asset management processes, expected benefits in risk management and others.

Digital twin (DT) is a solution for presenting reality in a virtual world. DTs have been discussed in the literature only recently. The aim of this work is to review and analyse literature connected to DTs. Under a systematic literature review the authors searched databases for the information how DTs can support organization operations and how they can support sustainability of companies. A literature review was performed according to a developed research methodology, which covers research questions and keywords identification, selection criteria and results analysis. Databases, such as Web of Science, Scopus and Science Direct, were searched. The titles, abstracts and keywords were searched for works related to digital twins, sustainable development and manufacturing processes. Moreover, the search was focused on real-time monitoring, data, decision-making etc. The keywords used in the searching process are specified in the methodology. Afterwards, quantitate and qualitative analysis were performed taking into account number of publication, year of publications, type of publication, based on keywords and available information concerning the papers. Deeper analysis was performed on available full texts of the papers. The main goal of this paper was to assess how much the specified problem is discussed in literature in the context of production organizations and real-time and what kind of topics are present in publications to indicate future research needs.

The aim of the paper is to present the possibilities and limitations of using the Digital Image Correlation systems. In order to assess the measurement inaccuracies the measuring volume 1250 × 1100 mm was analysed using two cameras with sensor resolution 6 megapixels. It was stated very good accuracy of the line segment length change. It causes that observation of crack widths can be considered as precisely. Some practical information concern how determine the compatibility between crack width measured traditionally and by using DIC are given. In the second part of the paper the results of the tests concerning capacity of interface between two concrete casting at the same time were presented. Use of the optical measurement system Aramis enables the analysis of the deformation, determination of failure mode of the tested specimens and limit displacement between edges of the interface.

This paper proposes the application of the digital numerical control (DNC) technique to connect the smart meter to the inspection system and evaluate the total harmonic distortion (THD) value of power supply voltage in IEEE 519 standard by measuring the system. Experimental design by the Taguchi method is proposed to evaluate the compatibility factors to choose Urethane material as an alternative to SS400 material for roller fabrication at the machining center. Computer vision uses artificial intelligence (AI) technique to identify object iron color in distinguishing black for urethane material and white for SS400 material, color recognition results are evaluated by measuring system, system measurement is locked when the object of identification is white material SS400. Computer vision using AI technology is also used to recognize facial objects and control the layout of machining staff positions according to their respective skills. The results obtained after the study are that the surface scratches in the machining center are reduced from 100% to zero defects and the surface polishing process is eliminated, shortening production lead time, and reducing 2 employees. The total operating cost of the processing line decreased by 5785 USD per year. Minitab 18.0 software uses statistical model analysis, experimental design, and Taguchi technical analysis to evaluate the process and experimentally convert materials for roller production. MATLAB 2022a runs a computer vision model using artificial intelligence (AI) to recognize color objects to classify Urethane and SS400 materials and recognize the faces of people who control employee layout positions according to their respective skills.

In October 2018, local digital radio was launched to cover the agglomeration of Wroclaw. The implementation of this undertaking required many tests, including qualitative ones, that refer to both music and speech. This paper presents the results of subjective tests based on the evaluation of speech quality of signals recorded at various points in Wroclaw. Measurements were carried out in accordance with the recommendations of the International Telecommunication Union as well as in ordinary acoustic conditions in listeners’ flats. The rating was made for male and female voices. The most important conclusion is that for speech signal assessment in meaning of the quality the test conditions do not influence the obtained results. The other fact confirmed in the experiment was that the receiving place of DAB+ signal in the Single-Frequency Network also does not affect the perceived voice quality.
