Published: December 2024

Abstract
The conventional quality control method of earth-rock dam is insufficient to meet the requirements of intelligent and fine management of dam filling construction in the new stage. With the expansion of construction scale and the overall improvement in information technology level, the traditional compaction quality control methods no longer meet the demands of modern mechanized rapid construction or provide real-time compaction information for engineering contractors. In response to the current conventional design and construction schemes for earth-rock dams, an intelligent real-time monitoring system established in this paper for compaction construction of earth-rock dams. This system utilizes advanced Beidou high-precision positioning and navigation technology, vibration-sensing IoT technology, real-time processing of massive construction information, and BIM technology. It achieves real-time intelligent monitoring of key compaction processes in dam construction and refined management of unit engineering. The intelligent system established provides crucial technical support for the safe and reliable operation of water conservancy and hydropower projects. Simultaneously, it enables real-time, remote, and intelligent monitoring of dam construction processes, significantly enhancing the technological content and informatization level of water conservancy engineering construction.

Published: December 2024

Abstract
The proposed extension to the conventional circuit co-simulation (CCS) method reliably and efficiently introduces arbitrary matching networks into CCS routines and is here dubbed as matching circuit co-simulation (MCCS). It further achieves coil tuning for resonance and an optimum scattering parameters condition that resembles a fully matched coil. Combined with magnetic resonance integral equations (MARIE), the proposed MCCS further accurately produces a full EM simulation of the coils. We first validated MARIE with the MCCS routine to use it to model simple single-channel coils and parallel transmit (pTx) head arrays coupled with Duke, a digital human body model. Having successfully validated the MCCS routine, we swept through both tuning and matching network parameters to optimize the coil. While optimizing for all parameters simultaneously is a viably efficient option for coil models of low complexity, these models are not realistic, and we found that it becomes a highly computationally expensive problem to solve for more complex coil geometries, such as birdcage coils and pTx coils with higher number of channels, especially when shielding is included. Consequently, we separated tuning and matching into two steps, by first tuning the coil to the right frequency, and then introducing matching networks to enhance the power transmission into the body. We observed lower on-diagonal S-parameters after matching in all pTx coils, but 1 coil still had strong cross-coupling. Finally, electromagnetic fields obtained via MARIE for separate port excitation were successfully combined using MCCS.

and compute the Killing spinor equation on the BTZ geometry, looking for BPS solutions on the entire space of parameters. We focus our attention on defects that represent geometries with integer angular excesses corresponding to specific negative values of the BTZ mass, extending other results in the literature to all real values of mass and angular momentum. We argue that, in the semiclassical limit, the BPS defects can be associated with degenerate representations of the Virasoro symmetry at the boundary. The case of non-diagonal representations, describing stationary, non-static defects, is also discussed.

Authors: Turdiboyev Abduvali , Akbarov Dilmurod , Norboev Anvar , Safarov Kholiyor Sayyid , Mamutov Muxammedgaliy 
Published: December 2024

Abstract
The article discusses the issue of increasing the efficiency of plant nutrition by treating liquid organic and mineral fertilizers with an electro-hydraulic effect. The amount of nitrates in water is reduced to 1.1 mg/l due to electro-hydraulic treatment. This creates the possibility of feeding plants and at the same time eliminating E. coli bacteria in liquid fertilizers from 2.23 mg/l. up to 102.7%, i.e. 82.55% compared to the control in exchange for its neutralization, which can prevent it from passing through the plant into the human and animal body, resulting in human health being maintained. As a result of the research, a process for electrohydraulic processing of liquid fertilizers was established, where the following processing modes and parameters were established to ensure the degree of grinding of solid particles in the liquid, processing voltage: U = 24 kV, capacitor capacity: C = 0.8 μF., number of pulses: n=175 pulses, which turned out to be sufficient. Due to electro-hydraulic processing the rate of fertilizer uptake by plants has been improved over existing technology by optimizing the breakdown of coarse fertilizers into liquid solution through electro-hydraulic treatment of liquid fertilizer solutions. As a result, it was possible to increase the yield to 33 g for tomatoes and 37 g for cucumbers per 1 hectare owned by the farm using the method of electro-hydraulic treatment of liquid fertilizers.
Archetype of self-learning classification of production impacts on the environment for sustainable development
Authors: Tsyganov Vladimir 
Published: December 2024

Abstract
The article is devoted to system engineering and development of eco-management technologies for sustainable development. At the top level of this corporation is the boss, making decisions regarding the sustainable development of the corporation, taking into account its impact on the environment. At the lower level is the production unit, the manager of which can use environmentally friendly technologies. The situation is studied when the boss does not know the capabilities of these technologies to reduce pollution from the production unit due to stochastic interference. In order to minimize environmental risks of production, the boss assigns the manager to one of two classes, depending on the pollution of that unit by the environment. For this purpose, procedures for forming a standard of environmental pollution, as well as assigning classes are used. Knowing these procedures and taking advantage of the ignorance of the boss, the manager can get a higher class by manipulating pollution. The game of the boss with the manager choosing pollution in such a way as to increase own objective function is studied. An archetype of self-learning classification of environmental impacts is formed, including optimal procedures for standardization and classification. It has been shown that the use of this archetype is sufficient to motivate the manager to minimize environmental pollution of the production unit even under stochastic interference.

Abstract
The study of water bodies using remote sensing data and Geographic Information System (GIS) technologies is crucial for effective water resource management. This research focuses on monitoring the Talimarjan water reservoir, a vital water source in Uzbekistan, by leveraging satellite imagery and GIS tools. Remote sensing offers a cost-effective and comprehensive approach to assess various parameters, including surface area, water quality, and seasonal fluctuations in water levels. By utilizing multi-temporal satellite data, changes in the reservoir’s volume and surrounding vegetation were analyzed. The integration of GIS technologies facilitated the mapping and spatial analysis of these changes, enabling the identification of trends and potential risks, such as sedimentation and water loss. The combination of remote sensing and GIS provides valuable insights into the health and sustainability of the water reservoir, aiding in decision-making for water management authorities. This study demonstrates the effectiveness of these technologies in environmental monitoring, highlighting their potential for broader applications in the management of water resources in arid regions. Through accurate, real-time data, remote sensing and GIS help in ensuring sustainable water use, promoting efficient resource management, and mitigating the impacts of climate change on water bodies.

Published: December 2024

Abstract
The paper presents the development materials for a combined drying unit for agricultural products with IR radiation, operating in a closed-loop mode. Due to the constant uniform movement along a closed loop, the entire mass of the product being dried is uniformly coated with a flow of drying agent and is subjected to intensive heat treatment. The superimposed effect of IR radiation in combination with convective heat exchange intensifies the process of heat and mass exchange and reduces the drying time.
Installation of a spindle surface cleaner of cotton-picking machines to prevent greening
Authors: Shoumarova M , Abdillayev T , Yusupov Sh A 
Published: December 2024

Abstract
The primary drawback of vertical-spindle cotton-picking machines is considered to be the lower completeness of crop collection in the hopper, which primarily occurs due to the rapid greening of spindle surfaces. On these machines, brush strippers are installed to clean the spindles from greening, which simultaneously remove the cotton windings from the spindles. Attempts by designers to install special devices on machines for cleaning the spindle surfaces from greening have not yielded positive results. Consequently, a significant portion of operational time is spent on washing the spindles. The authors have developed a design for brush spindle cleaners, the installation of which does not require modifications to the existing design of the harvesting apparatus. Calculations indicate that the installation of the proposed cleaner will enable effective cleaning of the spindle surface, thereby enhancing the completeness of collection by the vertical spindle.

Published: December 2024

Abstract
In this article, a comprehensive analysis of existing materials, hardening methods, design and features of the work of parts in the composition of aggregates is carried out. Based on this analysis, the choice of material for the base and reinforcing coating was carried out, and the most effective ways of strengthening the blades of the straw spreader were determined, which are installed on combines instead of similar imported parts. In the course of the study, the spread of blanks and hardened parts by weight, the degree of wear of knives in real operation, as well as the chemical and phase composition, structure and properties of reinforcing coatings were studied. 65G steel is proposed as a modern import-substituting material, and 6HV2C steel is proposed as a promising one. To increase the hardness and wear resistance of the knife blade, the technology of induction surfacing of modified hard alloys (composites) using high-frequency transistor converters (inverters) with a programmable mode is proposed. This technique makes it possible to achieve a more uniform heat distribution and ensure high accuracy of temperature control during the surfacing process, which improves the mechanical properties of the coating. The use of boron carbide and spherical tungsten carbide as a wear resistance modifier makes it possible to increase the hardness of the coating to 62-67 HRC, suppress the growth of dendritic structures, increase the adhesion of the functional filler to the composite matrix, reduce dispersion and increase the microhardness of the carbide phase, which together increases the potential wear resistance of the coating. The use of induction surfacing of modified hard alloys on knife blades contributes to a significant increase in their service life by increasing resistance to mechanical damage and wear.

Authors: Amin R , Rajagukguk S G , Wulandari F T 
Published: December 2024

Abstract
Water consumption of mining workers is a crucial factor in the environmental impact assessment but is often overlooked by the mining company. In addition, water consumption for mining activities is not reflected in some domestic water consumption standards such as SNI and PUPR standards. Therefore, calculating the rate of clean water demand is important to estimate water supply, organize and manage water distribution, and determine the waste water treatment plant (WWTP) capacity. The purpose of this study was to identify clean water consumption of mine workers at the contractor Lati Site of PT. Berau Coal, East Kalimantan Province per person per day. We conducted a direct measurement of water usage using the installed flow meters, and employed assumptions such as piping leakage and roster day-off to calculate clean water consumptions. Compared to the existing standards, clean water consumption at Lati Site was much greater, up to 229 litres per head per day whereas the water usage in the mining camp was 156 litres per head per day.
