Scientific research in the area close to the Russian Antarctic station Vostok has been carried out since its founding on December 16, 1957. The relevance of work to study the region is steadily increasing, which is confirmed by the Strategy for the Development of Activities of the Russian Federation in the Antarctica until 2030. As part of the Stra...

The stand uses a completely transparent soaring tube of same cross section along the entire length, and the soaring velocity is measured using a Pitot-Prandtl tube, freely moving along the cross sectional plane of the soaring pipe, which makes it possible to measure the air velocity in various airflow points.

The model relates to mining, in particular to devices for taking samples from the upper layer of bottom sediments of subglacial reservoirs, capable of walking along the bottom surface, with the possibility of delivering them to the required depth through a well previously drilled in the ice.

Increasing the visibility of representation for objects studying in the process of solving basic problems related to descriptive geometry (DG) significantly improves the understanding and perception of the discipline by students. A team of authors representing St. Petersburg Mining University’s DG and Graphics Chair developed their own projects, wh...

It was developed a new technique to assess micro- and mesopores with sizes below a few nanometers. The porous materials with hierarchical fractal-percolation structure were obtained with the sol-gel method. The tetraethoxysilane hydrolysis and polycondensation reactions were performed in the presence of salts as the sources of metal oxides. The por...

A model is developed for the formation of porous intragranular architectonics of nanostructured polycrystalline layers of lead chalcogenides for photodetectors and IR emitters. The layers are obtained under the conditions of thermal evaporation in a quasi-closed volume by the "hot wall" method followed by sensitizing heat treatment in an iodine-con...

The paper states that the current conditions in which the education system is located, and the rapid development of IT require constant improvement of methodological materials, taking into account the full capacity of the current software. Examples of programs necessary for preparation of methodological materials for high-quality classes are given....

The possibilities of Wolfram Mathematica (WM), which is a package of symbolic mathematics, are endless. In this paper are investigated the possibilities of WM software product contextualization in the process of geometric-graphic teaching of students; is considered the experience for using a set of WM computational algorithms in teaching practice....

The paper considers a three-stage technology for angular rolling of the pipe workpiece. This technology facilitates the expansion of the range of flange parts available by eliminating a number of drawbacks of the known methods of metal forming. In the presented paper, we analyze the results of numerical calculations and experiments, as well as the...

The research relevance is due to the growing interest of teachers in introducing Augmented Reality (AR) technologies into the course of Engineering and Computer Graphics (ECG). The research aims to study the current state of knowledge and practice of existing courses using AR-technologies, including those for geometric-graphic training of high educ...

The COVID-19 pandemic caused a serious crisis in the Russia’s education system, associated with the simultaneous universal transition to distance learning, which required the mobilization of all information and communication resources, and intensification of efforts to create conditions for e-distance learning implementation. In this paper the orga...

In this paper is investigated the possibility of Augmented Reality (AR) technologies contextualizing in teaching methods for “Descriptive Geometry” (DG) student course. The aim of the investigation was the study of the current state of knowledge and practice in the field of DG students teaching with the help of AR-technologies, and identification o...

This study’s relevance is determined by the absence of serious research, science-based, tested and verified programs and training materials related to the use of Augmented Reality (AR) technologies when getting students education in Engineering and Computer Graphics (ECG). The study’s aim was the introduction of AR-technologies in the project activ...

Engineering practice cannot and will never be successful without spatial imagination and thinking, deep knowledge of geometric methods and ways for solution of engineering problems, comprehensive understanding of specificity and geometric features of technical objects and their images, understanding of labor organization impact on these processes e...

A new technique for assessing the strain state of metals is described using the technology of cold rolling with inclined rolls, providing for joint use of mathematical modeling methods and scanning probe microscopy. Details with flanges are produced by means of cold rolling with inclined rolls technology of pipe workpieces. The Gleeble 3800 was use...

The paper reviews challenges associated with designing of equipment required to implement the selected technology of penetration into Subglacial Lake Vostok in Antarctica. It describes the design process of inertial mechanical reamer, which is required for one of the stages of the proposed penetration technology. The initial design of the reamer wa...

The research focuses on mathematical methods of mining pressure forecast to develop rational support patterns for mining tunnels and to ensure safety of mining operations. The purpose of research is to develop the methodology of applying advanced calculation methods and software solutions based on neural networks to reduce dispersion of factors inf...

In conditions of global information system development, when work on creation of software training resources has been transferred in the rank of priority tasks for Russian Federation’s education modernization, it’s really necessary for each high educational institution to develop its own e-learning tools that meet not only the Federal state educati...

The paper reviews challenges associated with developing a technology for penetration into Subglacial Lake Vostok in Antarctica. It outlines prerequisites indispensable for further surveys of Subglacial Lake Vostok using Borehole 5G-3 and describes a technology that ensures compliance with these requirements. Design elements of the drilling assembly...
