The implementation of Industry 4.0 solutions in Polish enterprises entails both certain barriers and significant potential for changes and numerous benefits. These barriers may result from the costs of implementation of new technologies, the need to adapt employees to new skills and concerns about data security. However, by overcoming these difficulties, companies can benefit from the enormous potential for changes such as increasing production efficiency, optimizing logistics processes or im-proving product quality. Moreover, the use of Industry 4.0 technologies can contribute to increased innovation, increased competitiveness on the global market and the creation of new jobs. As a result, the benefits of implementing these solutions support Polish enterprises to actively engage in digital transformation, despite the barriers they encounter. The objective of this article is to confront the benefits and potential for changes resulting from the implementation of modern technologies with the barriers that limit this process. The statistical assessment of the differences between the barrier assess-ment values and the assessment of benefits from the use of technology, as well as between the barrier assessment values and the assessment of the potential for changes, was based on the non-parametric Mann-Whitney U test. The study covered representatives of 236 enterprises who mainly held mana-gerial positions at various levels of management staff or persons designated by them who were re-sponsible for research and development activities in the surveyed entities. As a result, it was indicated that the level of involvement in technological transformation among Polish enterprises is moderate. Almost 67% of all the surveyed entrepreneurs can characterize specific Industry 4.0 solutions. Among them, only approximately 6% can be defined as highly digital companies that already have partially digitized operational processes. Moreover, enterprises see more potential benefits and potential changes from the introduction of Industry 4.0 solutions than barriers to their implementation. This study is dedicated to both authors dealing with Industry 4.0 issues and entrepreneurs implementing modern technologies in their companies.

This paper describes the process of designing and implementing a Turing machine simulator application. The created desktop application is distinguished from other solutions by the use of the latest technology and offline operating. The various stages of the project are described, such as defining requirements, creating UML diagrams, and prototyping the user interface. A MVVM architectural model used in building the application is presented. The issues of controls, data binding, and message passing found in the Avalonia package are addressed. The unit tests created and the exploratory tests performed are also described.

We discuss a quantum circuit construction designed for classification. The circuit is built of regularly placed elementary quantum gates, which implies the simplicity of the presented solution. The realization of the classification task is possible after the procedure of supervised learning which constitutes parameter optimization of Pauli gates. The process of learning can be performed by a physical quantum machine but also by simulation of quantum computation on a classical computer. The parameters of Pauli gates are selected by calculating changes in the gradient for different sets of these parameters. The proposed solution was successfully tested in binary classification and estimation of basic non-linear function values, e.g., the sine, the cosine, and the tangent. In both the cases, the circuit construction uses one or more identical unitary operations, and contains only two qubits and three quantum gates. This simplicity is a great advantage because it enables the practical implementation on quantum machines easily accessible in the nearest future.

The paper is based on a thesis with the same title. The purpose of this thesis is to analyse D-Wave devices using quantum effects. The research focuses on demonstrating the advantages and disadvantages of a company moving away from the circuit model in its computers. The subject of the research is the used adiabatic model of quantum computing based on the mechanism of quantum annealing. The research is based on publicly available, comprehensive documentation of D-Wave Systems. On the basis of scientific papers, conferences and information contained in websites, controversies, disadvantages and advantages of the solutions adopted have been described.

Badania zaczynów i zapraw dojrzewających przez wiele lat są istotne z tej przyczyny, że zachodzące w długiej perspektywie czasowej zmiany składu i struktury pod działaniem wielu czynników zewnętrznych i wewnętrznych stanowią potencjalne zagrożenie dla trwałości obiektów budowlanych, których czas życia jest określany na ogół na 50-100 lat. W pracy porównano skład fazowy i mikrostruktury zaczynów cementowych i belitowych dojrzewających 13-40 lat. Wykorzystano następujące techniki badawcze: rentgenowską analizę dyfraktometryczną (XRD), termiczną analizę różnicową z termograwimetrią i analizą gazów (DTA, TG, DTG, EGA), elektronową mikroskopię skaningową (SEM), mikroanalizę rentgenowską (EDS), analizę metodą elektronów wstecznie rozproszonych (BSE). Prześledzono zmiany zawartości wodorotlenku wapnia i stopnia karbonatyzacji w funkcji składu wyjściowych faz bezwodnych. Wskazano na wiele podobieństw łączących zaczyny cementowe („młodsze”) i zaczyn belitowy („starszy”).

Investigations of pastes and mortars stored for many years are important due to the fact that long-term changes in composition and structure under the action of many external and internal factors pose a potent threat to the durability of building objects whose life time is usually defined as 50-100 years. In this work, comparative studies of the phase composition and microstructure of cement and belite pastes maturing for 13 and 40 years respectively were carried out. The following techniques were applied: X-Ray diffraction (XRD), differential thermal analysis with thermogravimetric and evolved gas analyses (DTA, TG, DTG, EGA), scanning electron microscopy (SEM) and backscatter electrons imaging (BSE) with energy dispersive analysis (EDS). Changes of calcium hydroxide content and degree of carbonation were investigated as a function of the initial unhydrous phase composition. Many similarities between the cement pastes (“younger”) and belite paste (“older”) were indicated.
