Satellite Monitoring of Salinization of Irrigated Soils in South Kazakhstan

The results of approbation of new approaches to monitoring and forecasting of soil salinity of irrigated soils, based on indirect detection of soil salinity using multi-year archives of satellite data, are presented. Research was carried out on example of irrigated lands of Maktaaral district of Turkestan region of the Republic of Kazakhstan. As an indicator of soil salinity level frequency and terms of soil leaching from salts are used, which are identified on the basis of multi-year archives of satellite data Sentinel-1,2 and Landsat-8 (from 2016 to 2022). Information about the frequency of soil leaching from salts and the year of the last leaching allowed ranking the fields by the degree of soil salinity. Comparison of the obtained information with the fine-scale soil map and with statistical data based on field surveys of the fields showed a good level of similarity of the soil salinity level of the test region. A similar approach can be used for other regions with irrigated soils subjected to secondary salinization. It does not require additional adaptation and is based on simple algorithms of recognition from satellite data of water surface.

Использование в конкурсных процедурах критериев оценки инклюзивных практик на основе доказательного подхода

<p>The work presents the results of approbation of the approach to expert evaluation of inclusive practices in educational institutions developed at the Institute for Problems of Inclusive Education of the Moscow State University of Psychology and Education based on the integration of inclusiveness criteria and evidence requirements. The assessment involved 25 federal experts on inclusive education, who evaluated 30 cases in three nominations of inclusive practices submitted to the federal stage of the competition. The assessors scored the applications by completing expert protocols, which were processed to determine the level of inclusivity of the practice (zero, initial, basic, or advanced). Then a reflective discussion was organized on the application by experts of the approach we developed to assessing inclusive practices according to the criteria of inclusiveness and evidence, the results of this discussion were subjected to thematic analysis. The study revealed that the distribution of expert assessments of inclusive practices by levels differs from uniform (p < 0,01), confirming the effectiveness of the criteria as an assessment tool. At the same time, the reproducibility of the results of the expert assessment turned out to be at an acceptable level (83%), taking into account the unreliability of differentiation of the zero and initial levels (sample of repeated measurements: N = 12). The thematic analysis of expert reflection showed the usefulness of evaluation criteria as a tool not only for examination, but also for the development of expert thinking of the experts themselves, as well as the professional development of the contestants. Also, the results of the thematic analysis revealed the need for a broad discussion and further study of the key categories of inclusion (diversity, participation, acceptance, etc.) to operationalize them more accurately as inclusion criteria.</p>

The direction of increasing the efficiency of marine power plants by using heat exchange elements that implement intensive methods of heat transfer, which are characterized by a predominant increase in heat transfer over aerodynamic resistance, is considered. The research method is mathematical modeling of processes in power plants at the level of their individual elements – heat engine, power, and technological heat exchangers. The adequacy of the mathematical model for research the efficiency of power plants is justified by the results of verification and validation by comparing the results of calculations with the results of a physical experiment that have a discrepancy not exceeding 9.3 %. The goal of the research is to improve the economic, environmental, resource and weight-size parameters of power plants by using heat exchange elements with the intensification of the processes of convective transfer of heat and mass by using finned surfaces with dimples. Thanks to the performance of dimple systems on the edges of round pipes with spiral-ribbon finning and elliptical pipes with lamellar finning, it is possible to increase the heat transfer coefficient up to 36 %, while the resistance coefficient of the beam remains unchanged. The use of heat exchangers with the proposed heat transfer elements as part of ship power plants with low-speed engines and gas-and-steam turbine units allows to improve their economic and environmental characteristics. It was obtained that for tankers of the PANAMAX type, the increase in the efficiency of the ship's power plant is 1.3 % due to the use of elliptical surfaces with plate finning and hole systems on the ribs in the utilization boiler. The ship's EEDI index decreased by 1.7 %. For container ships with a deadweight of more than 100,000 tons, the change in these indexes was 2.5 and 2.7 %, respectively. For a marine gas-and-steam turbine plant, the efficiency increase was 2.4 %. The presented mathematical model of the power plant is characterized by positive results of approbation for constructive and verification calculations of power plants in marine energy, transport, and industry.

COMPUTATIONAL-MODELING TECHNOLOGY FOR ASSESSING THE IMPACT OF PREDICTED DESTRUCTIVE PROCESSES IN CONCRETE ON THE BEARING CAPACITY OF BUILDING STRUCTURES

The discovery in recent years in the United States of the destructive processes in concrete of hydraulic structures (dams) and reinforced concrete contaminants of reactor halls of NPPs has led to great interest and attention to relevant processes as phenomena / factors that can significantly impair operational safety of facilities, in particular to lead to non-compliance with the requirements of nuclear and radiation safety for the operation of nuclear installations under the event of technological emergencies as well as under seismic influences. This issue is also relevant for Ukraine, where there are 15 NPP units under operation, and also more two units during a long time are under construction.It should be noted that currently known technologies for monitoring the technical state of building structures (BS) do not have tools for non-destructive testing of BS, which allow to reliably determine the belonging of the concrete of internal volume of BS to the degraded state and even more identify correctly the boundaries of degradation zones, the physical-chemical mechanism of occurrence and progression of degradation, the stage of development (evolution) of the process of the material destruction, etc.Taking into account the above mentioned problem - the practical lack of tools and technologies to detect and assess the impact of internal massifs of damaged concrete on the overall serviceability of BS - the authors of article (in frames of the search study) have elaborated and approbated the calculative-model approach of determining of the degree of loss of serviceability (bearing capacity) of investigated structure for the case of the postulated conditions - the most probable and dangerous totality of geometric and physicochemical parameters inherent in structurally damaged concrete in the area of its localization in the BS. This approach - formalized as a computational-modeling technology / procedure - involves the implementation of a certain computational algorithm, the description and results of practical approbation of which are presented in the publication.

The implementation of immersive simulators in teaching students in professional programs, educational practice, as well as in organizing and conducting professional excellence championships demonstrates approximately equal effectiveness in comparison with traditional teaching methods, except for the cases in which it is important to develop tactile skills in working with certain equipment. Using the example of the execution of VR simulators in the teaching of the subject “Technology” in the school course, the advantage of learning on real machines is demonstrated. It was discovered that the maximum pedagogical effect is achieved by adding VR simulators to the training course and by using a combined approach. VR simulators are necessary for work in the absence of workshops and serve as an important didactic propaedeutic tool when they are available. Conclusion. The domestic and foreign experience of using immersive technologies in educational and outreach activities is analyzed, the development projects of the Russian Federation in the field of immersive technologies are considered. The relevance, theoretical and practical significance of the development and implementation of the CIT model are substantiated. The results of approbation in educational institutions of secondary vocational and basic general education are presented.

Simulation of Spacecraft Moon Landing Control in Virtual Environment Complexes

The paper considers the task for simulation of final stage spacecraft landing on the Moon in virtual environment systems. To solve this task, methods and algorithms are proposed for the lunar module motion control with the implementation of fast attitude maneuvers and minimum fuel consumption during its deceleration. The spacecraft control is based on virtual sensors feedback and makes it possible to implement stabilization, reorientation, deceleration, maneuvers, hovering and soft landing of the spacecraft on the Moon. The work involves virtual reality technologies with the implementation of human interaction with a computer-synthesized environment. In this case, to control the spacecraft in manual mode, virtual hands are used that copy the movements of the operator’s hands and act on the elements of virtual controls (joystick, buttons, etc.) inside the spacecraft model. Approbation of methods and algorithms proposed in the paper was carried out in our software package of virtual environment system on the example for landing simulation of virtual model Orel spacecraft in semi-automatic mode. In this software package the spacecraft control in manual mode is implemented by data which transit from Oculus Rift CV1 VR headset and Oculus Touch controllers designed for tracking the operator’s head and hands, as well as displaying synthesized stereopair to his eyes. The simulation of spacecraft landing on the Moon was carried out for stages that begin immediately after the basic deceleration at an altitude of about 2 km and including the free fall of the lunar vehicle, its verticalization, horizontal and vertical deceleration, hovering, and soft landing. The results of approbation showed the adequacy and quality of the solutions proposed in the paper, which can be further used to create simulators designed to train cosmonauts how to control a spacecraft during landing on the Moon.

Professional Author's Training Methods Computer-Graphic Modeling for Participants of the Advanced Engineering School

The article presents a research view on the features of the organization of the process of teaching computer-graphic modeling for participants in the educational process within the framework of an advanced engineering school. It is shown that this direction is not innovative and the creative teams of university engineering schools have already gained some experience in quickly solving typical problems in the process of advanced training of a highly qualified specialist. At the same time, the authors of the article draw attention to circumstances that significantly limit the achievement of ambitious goals pursued in the implementation of pilot educational programs. The application of the participants of the advanced engineering school to bridge the gap between theory and practice looks especially declarative, given that the formation of even basic skills (spatial thinking) for many members of elite engineering training groups requires significant time costs. Today, in Russian universities, this problem is solved by traditional methodological methods as part of the teaching of the discipline "Engineering Geometry and Computer Graphics". The author's methods of teaching computer-graphic modeling outlined in the article are addressed to innovative teachers who realistically assess their capabilities when developing their own design educational products for students who have made a conscious choice in favor of an advanced engineering school. The article was written based on the results of approbation of the author's pedagogical initiatives in the educational process of the university (Perm Polytechnic University).

РЕЗУЛЬТАТЫ АПРОБАЦИИ АЛГОРИТМА ПОЗИЦИОНИРОВАНИЯ И ОПРЕДЕЛЕНИЯ ОРИЕНТАЦИИ ПОДВОДНОГО АППАРАТА ПО ДАННЫМ ОТ ГИДРОАКУСТИЧЕСКИХ МАЯКОВ

The article deals with the determination of coordinates and orientation angles of the autonomousunderwater vehicle (AUV) relative to the stationary landing platform using high-frequencynear-range hydroacoustic system. The navigation task implies maneuvering the vehicle and approachingthe underwater station, which is associated with the formation of zones with differentacoustic visibility of the station's emitters by the receiving elements of the vehicle. Three zones ofacoustic visibility can be distinguished. The first zone is characterized by observation of signals of allbeacons of the underwater station. As a consequence, this zone is the most informative for solving theproblem of positioning and orientation determination of the AUV. The second zone corresponds topartial reduction of the number of observed beacons, which does not critically influence the possibilityof problem solving. The third zone (landing) is defined by essential reduction of a number of observedbeacons, that, as consequence, considerably complicates the solution of the positioning problem,taking into account the increased requirements on accuracy at the moment of landing of thedevice caused by provision of safety. To maintain positioning accuracy and determine the underwatervehicle orientation in the landing zone, it is proposed to use the results obtained in the early stages ofapproach of the vehicle to the underwater station (the first and second zones). A mathematical statementof the problem is given in the work, and the algorithm of its solution is described. When findingthe AUV in the first and second zones, the solution algorithm consists of two subtasks. The first subtaskis a rough estimation of location vicinity and angles of vehicle orientation using K-nearestneighbors method; the second subtask is specification of estimations using pseudo-dimensionalmethod by solving system of algebraic equations with Levenberg-Marquardt algorithm. In addition,estimation of beacon emission time is carried out. At finding ANPA in the third zone the algorithm isreduced to solution of system of algebraic equations with use of forecast of time of signal emission bya beacon, received at finding of the device in zones one and two. The results of simulation modelingand results of algorithm approbation obtained using a mockup of the vehicle and a mockup of theunderwater station in the test pool are presented.
