Effects and Prospects of the Vibration Isolation Methods for an Atomic Interference Gravimeter

An atomic interference gravimeter (AIG) is of great value in underwater aided navigation, but one of the constraints on its accuracy is vibration noise. For this reason, technology must be developed for its vibration isolation. Up to now, three methods have mainly been employed to suppress the vibration noise of an AIG, including passive vibration isolation, active vibration isolation and vibration compensation. This paper presents a study on how vibration noise affects the measurement of an AIG, a review of the research findings regarding the reduction of its vibration, and the prospective development of vibration isolation technology for an AIG. Along with the development of small and movable AIGs, vibration isolation technology will be better adapted to the challenging environment and be strongly resistant to disturbance in the future.

Formalization of the problem of analysis of stationary modes of complex heat supply systems

On the basis of a systematic approach, the goals and functional tasks of the analysis of the steadystate hydraulic regime are formalized, as a proven practice of the methodology of decision-making in the field of commissioning and prospective development of complex heat supply systems of megacities. The use of a systematic approach to setting and improving the tasks of mode analysis allowed us to develop and implement an applied information system with an effective analyzing methodology for solving professional problems.

PROBLEMS OF DESIGN OF AGRICULTURAL COMPLEX

This article is devoted to the study of the experience of designing domestic and foreign agricultural facilities, the prospective development of the architecture of a suburban multifunctional agricultural complex for the cultivation, storage, processing and sale of agricultural products in Kazakhstan. As a result of a comprehensive study, architectural proposals were developed and functional zones were determined: a recreation area, greenhouses, a residential area, a landscape area, a recreational-type settlement (tourism, recreation and hunting) and a trade and fair zone.

Recent Development of Photodeformable Crystals: From Materials to Mechanisms

Photodeformable materials are a class of molecules that can convert photon energy into mechanical energy, which have attracted tremendous attention in the last few decades. Owing to their unique photoinduced deformable properties, including fast light-response and diverse mechanical behaviors, photodeformable materials have exhibited great potential in many practical applications such as actuators, photoswitches, artificial muscles, and bioimaging. In this review, we sort out the current state of photodeformable crystals and classify them into six categories by molecular structures: diarylethenes, azobenzenes, anthracenes, olefins, triarylethylenes, and other systems. Three distinct light-responsive mechanisms, photocyclization, trans-cis isomerization, and photodimerization, are revealed to play significant roles in the molecular photodeformation. Their corresponding photodeformable behaviors such as twisting, bending, hopping, bursting, and curling, as well as the potential applications, are also discussed. Furthermore, the challenges and prospective development directions of photodeformable crystals are highlighted.

The progress of mini black holes: principles and analytical astronomical observation techniques

Mini-black hole (MBH) is a concept first proposed by Stephen Hawking in the 1970s. Normally, exploring MBHs will enhance the understanding of quantum theory and gravity theory as well as be helpful in predicting the configuration of the early universe. Based on information retrieval, this paper summarizes the progress of MBHs and takes three major aspects: background, models, practical methods for observations, and analysis. Specifically, the descriptive equations are derived, and different models are discussed separately. These results shed light on the prospective development of quantum field theorem, general relativity, and string theory.

Preliminary Fluid Geochemical Survey in Tete Province and Prospective Development of Geothermics in Mozambique

An evaluation of the feasible development of geothermal energy in Mozambique is proposed based on some thermal springs geochemical characterization in the Tete region. Chemical and isotopic data suggest that the springs have a meteoric origin and do not show connection with any active magmatic system. The proposed circulation model suggests high depths infiltration of meteoric waters along faults and fractures in a system characterised by discrete permeability and reservoir temperature between 90 and 120°C. These results, jointly with low salinity fluids and corrosive components absence suggest that the geothermal system may be conveniently exploited for direct and indirect uses.

Prospects of Post-Crisis Development of the Passenger Air Transportation Market of the Republic of Azerbaijan

The purpose of the study is to present a model of the prospective development of the passenger air transportation market of the Republic of Azerbaijan in the conditions of overcoming the crisis caused by the negative impact of the COVID-19 pandemic. Based on the analysis of the activities of the national airlines «AZAL» and «Buta Airways», taking into account the statistical data of the passenger traffic growth of the Heydar Aliyev International Airport (Baku), as well as data on the development of the national tourism industry, a model of promising development of directions in the structure of the route network of the Heydar Aliyev International Airport is presented. The result of the research is the construction of a model for the prospective development of new directions in the structure of the route network of the Heydar Aliyev International Airport. The main principles of the post-crisis model of the development of the national market, according to the author, is the need to develop the segment of low-cost air transportation. The presented model of the route network development includes the development of the directions of the national budget airline «Buta Airways», as well as the expansion of cooperation with foreign budget airlines «Fly Arystan» (Republic of Kazakhstan), «Wizz Air» (Hungary), and in addition, the development of cooperation with Russian regional airlines, and first of all with the airline «Azimut» as one of the dynamically developing regional airlines of the Russian Federation.

Economic Assessment of Options for Prospective Development of Production Subsystem of Export-Oriented Coal Companies

The authors review the challenges and trends of the Russian coal exports and describe fields that are potentially attractive for exports in the new coal mining centers in the East of Russia. A conclusion is made that the only option available for the Russian coal industry in the eastern parts of the country is the export-oriented sustainable development in conditions when the global coal trade is shifting towards the Asia-Pacific region. Scientific and methodological support for the implementation of investment projects of Russian coal companies has been developed for the new economic conditions. The economic and mathematical model is proposed to assess the options of perspective development of production subsystem of an export-oriented coal company, which helps to define the parameters of a rational option to develop the coal sector including the volumes of annual expenses of investors to obtain the highest revenue from coal export.
