Abstract The evolution and current state of the technology for supplying ships from the shore under high voltage - alternative power from the shore (APS), known as “Alternative Maritime Power® (AMP®), cold ironing (CI) and high voltage shore connection (HVSC) are described. The structure of the system and existing methods of implementation, mandatory components, depending on the system version are considered. The need for national adaptations of the international versons, the unification of existing technical solutions and their development trends, taking into account high-voltage technologies is emphasized. Advantages and challenges of environmental impacts, expected phased tightening of environmental regulations, including the maritime legislation (the MARPOL convention), as well as promising initiatives in the context of global decarbonization trends are described. The need to take into account purposes and cargo capacity and regions of operation of ships, to develop the port infrastructure, and make clean electricity available is emphasized.

The article presents the current state and the directions of development of contemporary tanks. Trends in the development of armored weaponry as a structure were considered in four areas: firepower, mobility, protection and situational awareness of the crew. Examples of combat vehicles used in various armies of the world and their upgrading and planned construction works were described herein. Combat vehicles used in the German, Israeli, Russian and Polish armies were assumed to be the most representative for the purpose of this study. An attempt has also been made to assess the adopted and planned technical solutions.

Radiometric Detection

The lifespan assessment and maintenance planning of high-voltage power systems requires condition monitoring of all the operational equipment in a specific area. Electrical insulation of electrical apparatuses is prone to failure due to high electrical stresses, and thus it is a critical aspect that needs to be monitored. The ageing process of the electrical insulation in high voltage equipment may accelerate due to the occurrence of partial discharge (PD) that may in turn lead to catastrophic failures if the related defects are left untreated at an initial stage. Therefore, there is a requirement to monitor the PD levels so that an unexpected breakdown of high-voltage equipment is avoided. There are several ways of detecting PD, such as acoustic detection, optical detection, chemical detection, and radiometric detection. This paper focuses on reviewing techniques based on radiometric detection of PD, and more specifically, using received signal strength (RSS) for the localization of faults. This paper explores the advantages and disadvantages of radiometric techniques and presents an overview of a radiometric PD detection technique that uses a transistor reset integrator (TRI)-based wireless sensor network (WSN).

Introduction. Today, almost the only industry in the country that Ukraine can really be proud of and which is considered one of the most technologically advanced in the world is the development of card technologies, payment technologies and card infrastructure. The purpose of the article is to analyze the current state of electronic payment systems in Ukraine and highlight development trends. Results. The modern fintech directions in Ukraine are analyzed and examples of the impact of COVID-19 on the market of electronic payment systems for the last period are given. A number of trends are highlighted for further research in the field of electronic payment systems, which are now quite promising. Perspectives. Given the significant increase in non-cash payments, the problem of developing financial technologies and spreading awareness among the population has become especially urgent. It is necessary to improve not only the financial technologies themselves, but also the ways of providing them to clients and promoting modern financial technologies. Electronic payment systems can still be considered one of the most promising areas for future research.

The article presents problems occurring during remote temperature measurement of lashing clamps of bridge connections on high voltage poles using thermal imaging cameras. The basic metrological parameters of thermal imaging cameras are described. On this basis, typical errors made during the inspection of high voltage lines supplying power substations are presented using infrared cameras. Researching the possible solutions for the problems of remote temperature measurement of small objects of electricity power systems—on the example of lashing clamps of bridge connections on high voltage poles in the proposed paper and showing the basic metrological aspects and parameters of thermal imaging cameras are important because, in this way, it is observed to eliminate costly interruptions in the supply of electricity associated with the breaking of power lines. Small objects are quite difficult to be controlled and monitored on large grids and on large powerline poles; thus, it is very challenging to interpret the data offered by thermograms. The problem of remote temperature measurement of small objects in electrical power engineering is very important from the point of view of the quality and reliability of electricity supply. Obtaining early warning information about the occurrence of overheating, e.g., on lashing clamps of bridge connections, is very important, as it eliminates costly interruptions in the supply of electricity associated with the breaking of power lines supplying high voltage switchgears or substations.
