Opis:
The aim of the article is to analyze non-statistic methods of identifying key words (understood as units presenting special importance for a given culture and being a source of knowledge about it). The analyzed criteria of this identi cation are: the presence of the words in the given types of texts and in their speci c parts, undergoing semantic and pragmatic shifts, being a part of phraseo-logical units. The analysis is conducted mainly on the examples extracted form ChronoPress (The Chronological Corpora of Polish Press Texts 1945-1954) from 1945. The e ect of the survey is the evaluation of the abovementioned criteria in terms of their usefulness for identifying key words, followed by a description of the noticed problems and controversies as well as suggestions on finding solutions.

Opis:
Wireless sensor networks have received wide attention recently across the indoor and outdoor applications. On the other hand, more and more application scenarios require sensor nodes to be mobile, which imposes new technological challenges for security. Key management is the core for secure data communications among the resource-constrained sensor nodes. In this paper, based on the Group Diffie-Hellman key agreement protocols and the energy level of each node in the network, we propose Energy Aware Group Diffie-Hellman key management protocol for mobile wireless sensor networks. The simulation results show that the proposed key management protocol provide significant improvement in maximizing the lifetime of networks.

Opis:
In spite of the fact that digital signing is an essential requirement for implementation of e-governance solutions in any organization, its use in large scale Government ICT implementation is negligible in India. In order to understand the reasons for low-level acceptance of the technology, authors performed a detailed study of a famous e-governance initiative of India. The outcome of the study revealed that the reasons are related to the challenges concerning the use of cryptographic devices carrying private key and the complicated process of generation, maintenance and disposal of Digital Signature Certificates (DSC). The solution, for the challenges understood from the case study, required implementation of a certificateless technology where private keys should be generated as and when required rather than storing them on cryptographic devices. Although many solutions which provide certificateless technology exist, to date there have been no practical implementation for using biometrics for implementing the solution. This paper presents the first realistic architecture to implement Identity Based Cryptography with biometrics using RSA algorithm. The solution presented in the paper is capable of providing a certificate-less digital signature technology to the users, where public and private keys are generated on-the-fly.

Opis:
There is an ongoing debate about the fundamental security of existing quantum key exchange schemes. This debate indicates not only that there is a problem with security but also that the meanings of perfect, imperfect, conditional and unconditional (information theoretic) security in physically secure key exchange schemes are often misunderstood. It has been shown recently that the use of two pairs of resistors with enhanced Johnsonnoise and a Kirchhoff-loop - i.e., a Kirchhoff-Law-Johnson-Noise (KLJN) protocol . for secure key distribution leads to information theoretic security levels superior to those of today's quantum key distribution. This issue is becoming particularly timely because of the recent full cracks of practical quantum communicators, as shown in numerous peer-reviewed publications. The KLJN system is briefly surveyed here with discussions about the essential questions such as (i) perfect and imperfect security characteristics of the key distribution, and (ii) how these two types of securities can be unconditional (or information theoretical).

Opis:
The Verilog-A "Analogue Device Model Synthesizer" (ADMS) has in recent years become an established modelling tool for GNU General Public License circuit simulator development. Qucs and ngspice are two examples of open source circuit simulators that employ ADMS for compact semiconductor model construction. This paper presents a "turn- key" compact device modelling and circuit macromodelling system based on ADMS and implemented in the QucsStudio circuit design, simulation and manufacturing environment. A core feature of the new system is a modelling procedure which does not require users to manually patch, by hand, circuit simulator C++ code. At the start of QucsStudio simulation the software automatically detects any changes in Verilog-A model code, re-compiling and dynamically linking the modified code to the body of the QucsStudio cod e. The inherent flexibility of the "turn-key" system encourage s rapid experimentation with analogue and RF compact device models and circuit macromodels. In this paper QucsStudio "turn-key" modelling is illustrated by the design of a single stage RF amplifier circuit and the Harmonic Balance large signal AC simulation of a 50 Ω RF diode switch.

This article attempts to bring together the most important educational priorities which should be taken into consideration when planning education in a world recovering from a pandemic. Some of the priorities discussed here should have already been taken into account during the 20th century, whilst others are completely new and result from changes that have come about in the 21st century, such as increased arrogance, ignorance, authoritarianism, educational insecurity, contempt for nature, confusion and the promotion of the lies under the name of post-truth . The authors propose a holistic approach to the education process, focused on priorities. In turn, the definition of those priorities should result from the most important problems that affect humanity.

Difficult situations are unavoidable in every human's life. They may challenge a person to cope with them in order to overcome the obstacles. The search for personal resources that help one successfully deal with life's challenges has become, in recent years, one of the main issues for both psychology and pedagogy. Resiliency, understood as a personality trait is a subjective quality, which helps one to develop flexible and positive adaptation to difficult situations and to overcome them. The article aims to present the importance of resiliency and the possibilities for raising humans capable of coping with life's obstacles and everyday difficulties.

Opis:
We say that the sequence gn, n≥3, n→∞ of polynomial transformation bijective mapsof free module Kgn over commutative ring K is a sequence of stable degree if the order of gn is growing with n and the degree of each nonidentical polynomial map of kind gkn is an independent constant c. Transformation b = τgnkτ−1, where τ is the affine bijection, n is large and k is relatively small, can be used as a base of group theoretical Diffie-Hellman key exchange algorithm for the Cremona group C(Kn) of all regular automorphisms of Kn. The specific feature of this method is that the order of the base may be unknown for the adversary because of the complexity of its computation. The exchange can be implemented by tools of Computer Algebra (symbolic computations). The adversary can not use the degree of right handside in bx = d to evaluate unknown x in this form for the discrete logarithm problem. In the paper we introduce the explicit constructions of sequences of elements of stable degree for the cases c = 3 and c = n+2/4 for each commutative ring K containing at least 3 regular elements and discuss the implementation of related key exchange and multivariate map algorithms.

Opis:
Civilization changes related to the development of information and communication technologies require the formation of new competences in the society, the possession of which will determine the quality of life in the digital world and rational participation in cyberculture. The implementation of this task becomes the special responsibility of educational institutions that aim at stimulating the growth of interests of children and youth in the areas of knowledge crucial for the development of the information society. It is extremely important to take actions supporting the development of logical and mathematical intelligence and digital competences. Their possession is of key importance for the conscious, rational and creative use of new technical possibilities. One of the important initiatives supporting this task is the organization of classes within children’s universities. The article describes the projects undertaken at the Children’s University of the Humanitas University in Sosnowiec. Their main goal is to provide conditions for facilitating the development of interest in science, through its popularization. The main assumption is to implement the idea of active learning in the digital environment. Through experiencing and experimenting with the use of information technology methods and means, children and adolescents can develop competences necessary for efficient functioning in the information society.

Purpose: The aim of this study was to elucidate the role of regulation as a tool to create values for both business entities and individual clients due to competition development in the Polish market of rail transport services. Methodology: This study was of a conceptual character. It was based on the analysis of the notion of the rail transport services regulation and the main regulation problems that have appeared in the rail transport regulation practice so far. The analysis of literary sources as well as practice enabled the author to highlight the circumstances when the regulation becomes a necessity and to discuss the conditions for its introduction. Findings: Reviewing the regulation on Polish railway transportation market, the author presents a fundamental conclusion - despite all the changes on the market, regulation does not produce assumed results perceived as an increase of transportation role in economy. According to author, major improvement of institutional and marketing efficiency of regulation entity is essential, as it is relevant for producing favorable results concerning the way the market operates, behavior of the market players as well as building customer value. Originality: Market regulation is a new phenomenon in Polish rail transport. The study discussed the notion of regulatory service. A value-for-clients model was also offered, i.e. the clients of regulatory activities in the course of the competition development in the rail transport services.

The paper offers an analysis of lexical-syntactic structures based on the verb form viser typical of a scientific text, that is a text that follows quite a stable and rigid structure. A corpus-based analysis, achieved through the use of the Scientext corpora, runs across two dimensions. The first dimension is constituted by the subject matter of the text while the other dimension concerns the relation between the author of the text and the recipient. The analysis presented is a two-stage process. At the first stage, lexical-syntactic structures are singled out. The second stage is to assign those structures to the particular parts of the text, such as Introduction, Main body, Conclusion.

Opis:
The aim of this work is to show the importance of the expansion of teacher’s key competences, while also pointing out those other competences which are unavoidable in the pedagogical work. If one wants to meet the exigencies of time: vehement changes in science, technology, economy, the changing character of work, one has to learn during all his lifetime. To fulfil the personal and social interests, to improve the quality of one’s life: the life-long education of the individuals is very important – from maternal schools, through scholastic education, education in different institutions and in business, until the education as pensioners.

Key Performance Indicators
Opis:
Effective management of an online store requires learning about the behavior of its customers. This is possible thanks to the analysis of data provided by users. E-commerce systems and integrated tools provide more and more information about users, which raises problems regarding the selection of data for analysis that support decision-making processes. Hence the need to extract the most important information and build a customized indicator system. Theoretical considerations on the characterization of key performance indicators were undertaken in the paper. In order to identify them in e-commerce, key success factors for the purchasing process were proposed. Particular attention has been paid to methods that can positively influence the indications of key performance indicators. The aim of the article is to propose the key performance indicators (KPI) for the assessment of the purchasing process in e-commerce systems.
Skuteczne zarządzanie sklepem internetowym wymaga poznania zachowania jego klientów. Jest to możliwe dzięki analizie danych, które dostarczają użytkownicy. Systemy e-commerce oraz zintegrowane narzędzia dostarczają coraz więcej informacji o użytkownikach, co rodzi problemy dotyczące wyboru danych do analizy, które wspomagają procesy decyzyjne. Stąd potrzeba wyodrębnienia najważniejszych informacji i zbudowania dostosowanego systemu wskaźników. W pracy podjęto teoretyczne rozważania na temat charakterystyki kluczowych wskaźników efektywności. W celu ich identyfikacji w e-commerce zaproponowano kluczowe czynniki sukcesu dla procesu zakupowego. Szczególną uwagę zwrócono na metody, które mogą pozytywnie wpłynąć na wskazania kluczowych wskaźników efektywności. Celem artykułu jest zaproponowanie wybranych, kluczowych wskaźników efektywności (KPI) dla oceny procesu zakupowego w systemach e-commerce.

Opis:
Voice over Internet Protocol (VoIP) has been recently one of the more popular applications in Internet technology. It benefits lower cost of equipment, operation, and better integration with data applications than voice communications over telephone networks. However, the voice packets delivered over the Internet are not protected. The session initiation protocol (SIP) is widely used signaling protocol that controls communications on the Internet, typically using hypertext transport protocol (HTTP) digest authentication, which is vulnerable to many forms of attacks. This paper proposes a new secure authentication and key agreement scheme based on Digital Signature Algorithm (DSA) and Elliptic Curve Cryptography (ECC) named (ECDSA). Security analysis demonstrates that the proposed scheme can resist various attacks and it can be applied to authenticate the users with different SIP domains.

Opis:
Let K be a commutative ring and K^n be a space over K of dimension n. We introduce the concept of a family of multivariate maps f(n) of K^n into itself with invertible decomposition.If f(n) is computable in polynomial time then it can be used as the public rule and the invertible decomposition provides a private key in f(n) based public key infrastructure. Requirementsof polynomial ity of degree and density for f(n) allow to estimate the complexity of encryption procedurefor a public user. The concepts of a stable family and a family of increasing order are motivatedby the studies of discrete logarithm problem in the Cremona group. The statement on the existenceof families of multivariate maps of polynomial degree and polynomial density of increasing order with the invertible decomposition is proved. The proof is supported by explicite construction which canbe used as a new cryptosystem. The presented multivariate encryption maps are induced by special walks in the algebraically dened extremal graphs A(n;K) and D(n;K) of increasing girth.
