The article reviews and evaluates the factors affecting the revenue management system in hotel facilities. Based on the statistical data of the State Statistical Committee of the Republic of Azerbaijan for 2005-2023, it is determined here that at the current stage of the digital economy in the globalized world economic system, the service sector is one of the fastest growing sectors compared to other sectors of the economy and responds faster to the socio-economic processes taking place globally. The article reviewed the one-time capacity, room stock, revenue from the sale of rooms and total revenue of hotel facilities of the Republic of Azerbaijan for 2006-2023, and calculated the RevPaR indicator, which expresses the efficiency of their services, for these years. The study also conducted a correlation and regression analysis between the RevPAR indicator and revenue from the sale of rooms of hotel facilities in the Republic of Azerbaijan, and determined the extent to which an increase in revenue from the sale of rooms increases the RevPAR indicator of hotel facilities.

The article explains the elements that have the largest share in intellectual capital and explains the possibility of quantitative assessment of the specific weight of these elements in intellectual capital. Here on the example of the Republic of Azerbaijan on the basis of statistical data the value of works and services on intellectual capital in Azerbaijan is analyzed, as well as the dynamics of added value created at the expense of intellectual capital. In the article, the impact of added value created by intellectual capital on economic growth in Azerbaijan has been evaluated in the software package Eviews-12.

This article presents a calculation model based on the impact of tourism services and income of hotel enterprises, which have a special share in this service, on the gross product, GDP, labor resources, capital investment and working capital through econometric models. It assesses labor resources, GDP, investment in fixed capital and key indicators for the development of the tourism complex of the Republic of Turkey and provides relevant forecasts. In addition, the statistical significance of the model based on the Eviews software package was checked and its suitability for forecasting purposes was determined.

This paper presents a case study of a barley field experiment that was periodically scouted using a drone spectral camera. The camera has 4 bands so barley was scouted using 4 wavelengths of light – Green, Red, Red Edge and Nir Infra Red (NIR). Based on these wavelengths it is possible to calculate different vegetation indexes known in science and practice. In this paper, 15 such indices were used. The research work concerned the observation of correlation between individual wavelengths and corresponding vegetation indexes. This paper seeks to emphasize the importance of particular wavelengths and spectral areas in crop scouting

The Broadband Mobile Satellite Services (B-MSS) are extremely important not only for government (army and police), but for  many civil applications as car, aero, railway and ship communications. Probably they will be part of the future 5-G network development and their security work is very important too. The solving of the main B-MSS security problems needs entirely new approach. The aim of this paper is to analyze two new radio-communication principles, named Spatial Correlation Processing – Random Phase Spread Coding, from security point of view. They were proposed by the author a decade before as antenna transmit-receive beam forming methods with many applications in microwave frequency bands too.
