This work focuses on the possibility of practical application of two approaches ? classic least square method (LSM) and Huber?s M-estimator (HME) method ? to the analysis of time series of celestial objects? measurements. Using those methods, the values of dynamic selenophysical parameters were produced from the processing of observations of Mosting A lunar crater in relation to the lunar limb. The reason for the use of the two approaches ? LSM and HME ? at observations processing is that LSM in some cases does no...

In this paper we propose the criteria of an information model that will allow, based on input expert data, to derive a risk assessment of unmanned aerial vehicle (UAV) flights for mountainous environmental studies. To create an information model, it is necessary to develop a mathematical model of risk assessment and informative content of the model within the framework of the problem under study. For the model input, there is a space of mountainous terrain for which we define set of criteria as a threat to safety ...

The article deals with development of virtual tours to memorable places associated with the residency and activities of famous personalities of Russia using specialized equipment (Insta360 Pro panoramic camera with "fish-eye" lenses with the viewing angle of 200° and 3DVista Virtual Tour Pro software). When creating virtual tours, it was made possible to move from one time period (present time) to earlier historic periods for a memorial place under study, which allows user to independently conduct visual analysis ...

Currently every day the need for obtaining information from satellites and quadcopters is increasing. Various services and ordinary users have a need for automated processing of received information from satellites. However, automated processing raises a number of problems: different illumination of objects, their difference in different times for example at different times of the year, soil changes, river spills and forests before and after fires etc. However, topology allows you to preserve the shape of feature ...

Currently there are many spatial structures for storing information about raster and vector maps. There are many algorithms for calculating map information, each of which is applicable to a specific industry. Now there is a problem of the lack of a universal algorithm for obtaining information about the maps, which will allow you to store its scale, time of image creation, deformation, various rotations and other topological features of objects in the images. The article sets the task of developing a method for ex...

It includes: development of the technology for creating 3D models of cultural heritage objects for virtual reconstruction of historically significant territories; development of the technology for analysis o...

The digitalization of financial services at its current stage is characterized by high dynamics in terms of information technology used, with the expansion and complication of the relationship with consumers, which requires constant improvement of the forms and methods of management of organizations offering financial services. The emergence of phenomena such as cryptocurrencies, blockchain transactions, fintech companies, and others modify the financial services market, which is traditionally dominated by banks a...

When we carry out inference automation, the time required to complete the inference procedure is very important. The shorter the time, the more effective the procedure. If we carry out the logical inference procedure manually, then we make a choice of a sequence of steps. In this case, the person takes into account the specifics of the problem being solved. It does not act formally, but taking into account the substantial meaning of predicates. If we are going to shift the inference procedure to a computer, then w...

It is well known that the process of inference is generally non-deterministic. Therefore, to develop effective inference algorithms, the problem of managing the inference search is very relevant. The solution to this problem is complicated by the fact that the predicate calculus is unsolvable. There is no method for establishing general validity or its absence for an arbitrary formula for calculating predicates. Nevertheless, if the formula for calculating predicates is valid, then there is a procedure for establi...

The purpose of this paper is to study network simulation and modeling software and determine which tools are most suitable for designing a corporate computer network of commercial enterprise. The permanent improvement of automation tools, the integrated implementation of information processing and transmission systems in the enterprise structure require knowledge of all the advantages and disadvantages of new technologies to the smallest detail, the ability to use them as intended and, most importantly, effectivel...

The aim of this article is to create a risk analysis of selected school facilities which can be an auxiliary tool of security solutions against terrorism. Most terrorist attacks are focused on so-called soft targets - crowded places, which are not secure against violent attacks. Furthermore, attacks on school facilities abroad are frequent too. A wellprepared risk analysis is a necessary method to detect weaknesses and strengths of the security of a soft target. The university in Zlin in the Czech Republic was cho...

In today's world, shopping represents a significant part of everyone's life. The interaction between the customer and store staff has grown to be more critical than ever. To facilitate a pleasant and engaging shopping experience, we acknowledge a market gap and a real competition for developing innovative tools that can be used by both parties: the customers, which need their requirements fulfilled, and the store staff, that can use these tools to satisfy customers' needs further by targeting the correct audience....

Currently, particular attention is paid to the study of connection between geophysical phenomena and technogenic processes. At the same time, the structural parameters of the Earth?s internal structure and its core, change in natural characteristics of water basins as well as dynamics of oil and gas deposits are being investigated. This paper describes a new method for studying geophysical phenomena depending on the state of large water basins. With this purpose, we conducted a correlation analysis between astrome...

The article presents methodological approaches to the improvement of the environmental monitoring system. To increase the objectivity and to improve the visual aspects of data presentation during ecological monitoring, the authors proposed to involve remote sensing methods of the Earth and geoinformation technologies. The presented set of methods is effectively used for general, operational and background monitoring. The authors have developed an algorithm for monitoring the state of ecosystem components by remote...

This work aims at the creation of digital selenographic satellite maps (DSSM) using fractal geometry and multi-parameter harmonic analysis. The observational data for DSSM were produced by the ?Clementine?, ?Kaguya? and ?LRO? space missions. An electronic database on altimetry measurements was built and they were brought into the single reference system by robust modeling. Based on the produced data and the method of multi-parameter harmonic analysis, we developed a digital selenographic satellite map covering the...

This work focused on study fractal structures on Venus is performed on the basis of observations taken by the ?Magellan? spacecraft (NASA). The equipment of this artificial satellite allowed scanning almost the entire surface of Venus using a radar with synthesized aperture of S-band (12 cm) and a microwave radiometer as well as investigating topography by the special radar ? altimeter. The uncertainties in some data produced by ?Magellan? were filled by the information that had been collected before ? in ?Venera ...

Most of the time, in assessing a situation where a leakage of combustible gas is involved, the volume of the room where the release occurs and the volume of the released gas is taken into account, thus resulting in an average concentration of the fuel gas applied to the entire volume of the room. In some cases, when the source of combustible gas is close enough to the source of initiation, or when air currents converge at the location of the source of initiation carrying amounts of combustible gas, the explosive m...
