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.

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.

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.

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.

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.

The paper presents a novel implementation of a time-to-digital converter (TDC) in field-programmable gate array (FPGA) devices. The design employs FPGA digital signal processing (DSP) blocks and gives more than two-fold improvement in mean resolution in comparison with the common conversion method (carry chain-based time coding line). Two TDCs are presented and tested depending on DSP configuration. The converters were implemented in a Kintex-7 FPGA device manufactured by Xilinx in 28 nm CMOS process. The tests performed show possibilities to obtain mean resolution of 4.2 ps but measurement precision is limited to at most 15 ps mainly due to high conversion nonlinearities. The presented solution saves FPGA programmable logic blocks and has an advantage of a wider operation range when compared with a carry chain-based time coding line.
