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…

Steganographic systems are used for the transmission of hidden data in the original signal. Imperceptibility of hidden information is a critical parameter of steganographic systems. The article describes and compares two ways to determine masking curve for audio steganography algorithms. We checked the quality of…

This paper deals with the precision of the direction finding (DF) signal sources method basis on circular antenna array. An analysis of signal amplitudes and phases determined from the outputs in each of the antennas of the circular antenna array intended for work in the…

This paper focuses on an overview of research directions in the coexistence areas of radars and communication systems. This topic is related to modern passive and multiple-input-multiple-output (MIMO) radar systems that operate in the presence of ubiquitous wireless radio networks, in particular mobile cellular or…

Review of scientific literature and periodicals showed availability of a fairly large number of theoretical studies on the formation of loyalty programs, however, there are precious few works devoted to assessing the impact of loyalty programs on the level of quality and customer satisfaction, which…

Video Surveillance Systems (VSS) are one of the key components of intelligent transportation systems (ITS), which are used for monitoring vehicle traffic, as well as detecting traffic incidents and disruptions. VSS allow for real-time observation of people or objects, and registration of events for later…

Currently, the Republic of Moldova imports about 95% of its energy resources to cover domestic energy consumption, which leads to increased external vulnerability at the local energy security level. In addition, there is a major dependence on natural gas, as it has a share of…
