Opis:
In the era of common access to freedom on the Internet, there are more and more controversies between advocates of complete freedom and followers of the idea of limiting the usage of the global network’s resources. Should the Internet become a space of unlimited freedom? Contrary to common belief, the answer to such a question is not that obvious, although intuitively one would like to say yes. The Internet is basically an egalitarian tool of communication, a space of easy creation and transfer of content, for which the only limit is technology and unlimited human imagination. Freedom seems to be not only an immanent, but even a constitutive feature of the virtual space in which the Internet functions.

Opis:
Purpose: Identification of scores and opinions about licensed car maintenance and repair shops in Radom on the basis of the word-of-mouth message in digital social networks. Design/methodology/approach: Licensed car maintenance and repair shops located in Radom were selected for the research. There are 20 of them. In order to identify a word-of-mouth message about them, data available in Google Maps were used – both numerical scores and opinions. Total amount of 3561 entries was considered. A mixed quantitative-qualitative approach was assumed: the statistics of scores were analysed quantitatively, while the content of the posted opinions was analysed qualitatively. Findings: Average scores for all car maintenance and repair shops are included in the interval <4,0; 4,6>. The total weighted average score is 4,3. A sharp polarization among opinions was stated, resulting in dividing them into two groups: clearly positive and clearly negative ones. On one hand, opinions encompassing substantive marks of overall high service level, professionalism, competence and quickness in delivering services, contact and information, as well as friendly atmosphere and staff friendliness dominate among the positive ones. They are often posted by loyal customers, who repeatedly take advantage of the services. On the other hand, clearly emotional opinions, expressed as a result of a single incident of not fulfilling customer expectations in a blatant way or neglecting them dominate among negative ones. Research limitations/implications: Research concerning a limited geographical region. Research should be treated as a pilotage. Practical implications: Information concerning scores and opinions about car maintenance and repair shops can make a starting point for identifying the areas of service quality which demand improvement. Originality/value: An innovative assessment of service quality in car maintenance and repair shops performed with the use of word-of-mouth data available in a digital social network.

Opis:
The purpose of this article is to reflect on what freedom of speech in the web is. In the age of universal freedom of access to the Internet, controversy is growing between supporters of full freedom and supporters of legal restrictions on the use of global Internet resources. Should the Internet be the space of unlimited freedom? Surprisingly enough, the answer to this question is not obvious, although intuitively one would like to answer in the affirmative. By definition, the Internet is an egalitarian tool of communication, a space for free creation and flow of content, for which the only limit is technology and human imagination, whose boundaries cannot be determined. The global network is a field completely unregulated and not bound by any rules. This situation is slowly changing and legislators and courts are beginning to set the boundaries of online proceedings. People posting content on the Internet must do so with precaution so as not to violate the limits of freedom of speech, especially in the field of broadly understood public security, crime, morality, public order, other people’s personal rights, and confidential information.

Opis:
The digital elevation model (DEM) is one of the most critical sources of terrain elevations, which are essential in various geoscience applications. Most of these applications need precise elevations, which are available at a high cost. Thus, sources like the Shuttle Radar Topography Mission (SRTM) DEM are frequently accessible to all users but with low accuracy. Consequently, many studies have tried to improve the accuracy of DEMs acquired from these free sources. Importantly, using the SRTM DEM is not recommended for an area that partly contains high-accuracy data. Thus, there is a need for a merging technique to produce a merged DEM of the whole area with improved accuracy. In recent years, advancements in geographic information systems (GIS) have improved data analysis by providing tools for applying merging techniques (like the minimum, maximum, last, first, mean, and blend (conventional methods)) to improve DEMs. In this article, DEM merging methods based on artificial neural network (ANN) and interpolation techniques are proposed. The methods are compared with other existing methods in commercial GIS software. The kriging, inverse distance weighted (IDW), and spline interpolation methods were considered for this investigation. The essential step for achieving the merging stage is the correction surface generation, which is used for modifying the SRTM DEM. Moreover, two cases were taken into consideration, i.e., the zeros border and the H border. The findings show that the proposed DEM merging methods (PDMMs) improved the accuracy of the SRTM DEM more than the conventional methods (CDMMs). The findings further show that the PDMMs of the H border achieved higher accuracy than the PDMMs of the zeros border, while kriging outperformed the other interpolation methods in both cases. The ANN outperformed all methods with the highest accuracy. Its improvements in the zeros and H border respectively reached 22.38% and 75.73% in elevation, 34.67% and 54.83% in the slope, and 40.28% and 52.22% in the aspect. Therefore, this approach would be cost-effective, especially in critical engineering projects.

The paper presents test procedures designed for application - specific integrated circuit (ASIC) CMOS VLSI chip prototype that implements a synchronized oscillator neural network with a matrix size of 32×32 for object detecting in binary images. Networks of synchronized oscillators are recently developed tool for image segmentation and analysis. This paper briefly introduces synchronized oscillators network. Basic chip analog building blocks with their test procedures and measurements results are presented. In order to do measurements, special basic building blocks test structures have been implemented in the chip. It let compare Spectre simulateions results to measurements results. Moreover, basic chip analog building blocks measurements give precious information about their imperfections caused by MOS transistor mismatch. This information is very usable during design and improvement of a special setup for chip functional tests. Improvement of the setup is a digitally assisted analog technique. It is an original idea of oscillators tuning procedure used during chip prototype testing. Such setup, oscillators tuning procedure and segmentation of sample binary images are presented.

Human rights are “basic rights and freedoms to which all humans are entitled”. Proponents of the concept usually assert that all humans are endowed with certain entitlements merely by reason of being human. Human rights are thus conceived in a universalist and egalitarian fashion. Such entitlements can exist as shared norms of actual human moralities, as justifi ed moral norms or natural rights supported by strong reasons, or as legal rights either at a national level or within international law. However, there is no consensus as to the precise nature of what in particular should or should not be regarded as a human right in any of the preceding senses, and the abstract concept of human rights has been a subject of intense philosophical debate and criticism. As the new millennium emerges, trends in global human rights are changing. Human rights issues are crossing sovereign boundaries and are no longer just issues of the state. As more and more non-governmental organizations are growing, and the Internet expands and facilitates a quicker spread of information, there are more and more people raising concerns about human rights related issues. Some of these come from the increasingly larger and infl uential commercial sector including large, multinational companies, while the others are raised by ordinary people, being parts of different networks. The aim of this article is to examine the way social networks influence and change the methods of raising the awareness concerning human rights on one hand, but, on the other hand, to analyse how new media contribute to deepening global inequalities.

The paper presents the results of computer modelling of sanitary sewerage networks in selected towns of the Podlasie Voivodship. The calculation process of the design and operation of the sewerage network is labor-intensive and time-consuming, and it becomes necessary to use information technologies in the design process. Computer-aided design streamlines the entire process and enables a more accurate analysis of the work of the designed system. Nowadays, there is a growing interest in computer modelling. The concept of computer modelling is the construction and study of models that map reality or only a fragment of it. In practice, this is the main procedure used for research seeking to determine the behaviour of operational reality in given conditions. Computer models give the possibility to verify design assumptions and network operating conditions. Thanks to them, there is an opportunity to control real flows during operation.

Opis:
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.

Opis:
The dissemination of pro-Russia ideologies and associated visual motifs has become widespread and transversal, encompassing various communities within the digital ecosystem. This trend has been linked to the related cognitive warfare that targets public opinion, manipulates information, and undermines the credibility of democratic institutions. Regarding the Italian context, the period from 2019 to 2023 saw a dramatic increase in the number of actors promoting pro-Russia narratives. They included members of the novax and no-greenpass movements, conspiracy theorists, far-right organizations, neo-Nazi groups, and ultras. Concurrently, the digital ecosystem has contributed the spread of violent content and anti-establishment propaganda online. In order to identify and explore the Italian digital ecosystem affected by pro-Russia ideologies, this study exploits a combination of exponential discriminative snowball sampling and social network analysis techniques on the Telegram instant messaging service. Through this approach, this research provides insight into the organizational structure and dynamics of the network, identifying key actors and their relationships, and the dissemination patterns of pro-Russia and anti-establishment propaganda. This study proposes a new research methodology to study digital ecosystems permeated by cognitive warfare campaigns and provides a deeper understanding of the mechanisms through which such content is propagated, enabling the development of effective strategies for countering disinformation and promoting fact-based discourse.
