Precise localization systems are becoming more desirable from the point of view of commercial solutions and systems supporting user safety. The Bluetooth standard enables the implementation of such a system by providing methods allowing for the precise determination of the angle between the transmitting station…

The COVID-19 pandemic has had a significant impact on all areas of human life, both socially and economically. This paper aims to determine how the different age groups perceived the COVID-19 pandemic restrictions implemented in the tourism (hospitality) industry. The basis for the analysis was…

This paper presents a brief description of a simple method for hiding information in a digital audio signal. Despite its simplicity, the proposed method offers satisfactory results and has the potential for further development. The article also briefly describes the parameters to look for when…

Robotized machines are made mainly through a combination of disciplines: mechanics, electrical engineering and computer science. In the meantime, mechatronics was created from their connection. In order to create autonomous systems (to find the only solutions) it is necessary to connect as many robotics disciplines…

The article is devoted to stablecoin issues and their functioning features in the financial system. The nature of stablecoins and major ways of their use are revealed. Also impact of the global economic crisis on stablecoins is analysed. It was observed that at a time…

The rapid development of wireless communication systems has created a significant problem of radio resource scarcity. The results of measurement campaigns assessing the use of spectral resources indicate a low occupancy of the allocated frequency bands both in time and in space, which means low…

In this article we analyze a covert channel models based on superposition of signals. Based on several general models of hidden transmission we propose optimal modulation schemes for covert modulation. Proposed solution are analyzed from the point of view of detection performance. We focus on…

The article examines the impact of the short-term interest towards cryptocurrencies on the quality of prediction based on the Bass equation. Based on a series of tests to cut off short-term growth of the number of active wallets, it was found that there was no…

Currently, ensuring scientific and technological development is a factor in the success and prosperity of the economy. Scientific and technological progress increases the efficiency of the functioning of socio-economic systems and allows subjects of economic relations to successfully promote the results of their activities in…

This study discusses cryptocurrencies as security on property in the Polish criminal law. In order to shed light on the issues in question, the author introduces the reader to the approach to cryptocurrencies in the Polish criminal procedure and explains the essence of security on…
