Vermicomposting provides a green alternative to composting, which can reduce greenhouse gas emissions and improve soil health. As a result of existing waste management practices, greenhouse gases are released into the environment. Still, vermicomposting offers a sustainable solution by recycling organic waste into a soil amendment that improves soil health and increases crop yields. This study provides an in-depth overview of the benefits of vermicomposting, a practice that recycles organic waste materials into a nutrient-rich soil amendment called vermicompost, which can reduce greenhouse gas emissions, improve soil fertility, and boost crop yields by enhancing soil structure and microbial activity, thereby presenting vermicomposting as a sustainable way to recycle organic waste, while mitigating climate change, protecting soils, and boosting agriculture. This overview examines how vermicomposting organic waste lowers greenhouse gas emissions from landfills, improves crop yields through improved soil structure and fertility, and enriches soils by increasing microbial biodiversity and nutrient availability. Vermicomposting provides degradation and detoxification of organic waste with some nutrient-rich castings. The potential of these castings to improve soil health sparked interest among agricultural researchers. Crops fertilized with vermicompost thrived, producing higher yields and the nutrient density of the plants increased significantly. Emerging research reveals that vermicompost can fight against climate change. As an organic fertilizer, it enhances the ability of plants and soil to sequester carbon, decreasing greenhouse gases and also reducing emissions of methane and nitrous oxide compared to conventional fertilizers. With broader implementation, vermicomposting offers a meaningful path to combat climate change through regenerative agriculture.

Authors: Leni Linda Sari  , Muhammad Wakhid Musthofa
Published: September 2024

HIV/AIDS is a disease caused by a virus that attacks the immune system, causing the body's immunity to decrease. In this study, the SI (Susceptible-Infected) mathematical model will be studied to analyze the stability of the HIV/AIDS epidemic model, especially in the Special Province of Yogyakarta (DIY) based on age group and population density. The age group is divided into two subpopulations, namely children and adults. The analysis carried out is to determine the local and global stability of the equilibrium point of the disease-free and disease-infected model. The analysis uses the characteristic equation of the Jacobi matrix and the Lyapunov-La Salle invariance principle or uses the conditions of the threshold value of susceptible reproduction ratio (R1), infected reproduction ratio (R0), and infectious contact rate. (R2). For cases of HIV/AIDS data in the Province of the Special Region of Yogyakarta (DIY) with an initial population of 2016, obtained R0 = 0.027, R1 = 114.25, R2 = 0.93. For cases of HIV/AIDS data in the Province of the Special Region of Yogyakarta (DIY) with an initial population of 2016, obtained E1 = (924.280, 179.402, 0, 0). The disease-free equilibrium point is globally asymptotically stable, meaning that if the parameter values do not change then there are no infected individuals and the susceptible subpopulation of children and adults to a constant positive value.

Published: September 2024

A technical method of providing assistance to injured people in the event of an emergency, namely, in the event of a collapse of structures, is proposed, since it is not always possible to carry out urgent operational dismantling of collapses and rescue people in the process of performing emergency and search and rescue operations. In these circumstances, depending on the ambient temperature, the human body may be subjected to hypothermia or overheating. In the same conditions, the rescuers themselves may find themselves nearby, when the time for extracting the victim for some reason is delayed. One of the ways to maintain the vital activity of the human body can be the supply of a heated or cooled air flow, which can be obtained from the Rank–Hilsch vortex tube. The air is compressed by a compressor, either portable or powered by a fire truck engine.

The issue of creating robotic anthropomorphic mechanisms called exoskeletons for humans is relevant. The exoskeleton design became practically possible due to technological developments, creating powerful computers, sensors, and detectors, collecting info about human movements, and advances in control theory. Introduction of available achievements in the domain of exoskeleton engineering and design, as well as exoskeleton parts and their control methods, protected by patents, to a general audience is the objective of the article. The research methods are analysis of patents and scientific publications on the topic of exoskeletons, and graphical processing of research results. The result of the conducted research is the survey of the patented exoskeletons available in the scientific world. It has been found that the available exoskeleton models are still not user-friendly enough. Therefore, the authors of the article developed and patented a model of an exoskeleton with variable-length links. The model of practical implementation of variable-length link based on using magneto-rheological fluid and adjusting the link stiffness by applying an external magnetic field has been proposed. The proposed model augments the exoskeleton user experience. It has been found that intense publication growth in scientific journals on researched topics started after 2011. The number of published exoskeleton patents increased almost tenfold in the past ten years by 2021. All these demonstrate significant interest in exoskeletons design.

Published: September 2024

The practical application of system analysis procedures to the development of a methodology for assessing the level of environmental safety of a high-tech natural and technical geosystem (HNTG) is proposed. Using the structural scheme of material flows, it is shown that the ecological state of the HNTG is formed by microelectronics industries, vehicle and life support systems of the city, and the main anthropogenic load falls on the atmosphere. The factors determining the environmental safety of HNTG are presented in the form of a «tree» of causes of safety violations, and the priority of their consequences is determined by the method of expert assessments. It is determined that emissions from microelectronics industries are of the greatest importance for the ecological state of HNTG, which allows limiting the effect of the methodology by assessing the level of environmental safety of the atmosphere. It should contain criteria and indicators for evaluating all internal and external anthropogenic loads of the atmosphere of the HNTG in accordance with the structural target model – the tree of assessments and follow the hierarchy of tasks in the form of a tree of goals. Pollutants from microelectronics production exceeding the environmental technology intensity of HNTG require special attention to the assessment of their safety and the nature of their distribution in the atmosphere.
MODEL FOR CALCULATION OF THE ENERGY POTENTIAL OF A SATELLITE RADIO LINK WITH ACCOUNT OF THE TRAJECTORY

Published: September 2024

A model of satellite communication channel taking into account the trajectory, specifically developed for low Earth orbit satellite constellations, is presented. Low and high orbits have different advantages and limitations. To efficiently utilize resources in low Earth orbit satellites, it is necessary to forecast changes in the energy potential and adapt the parameters of satellite modems. For this purpose, there are such programs as Computer-Aided Design (CAD) "Albatross" for evaluating the dynamics of resource changes. However, a realtime model has been developed for the operational management of modems, allowing the construction of temporal diagrams depicting changes in the energy potential of communication channels. The development of such models can be performed in the LabVIEW environment, a software developed by National Instruments for creating virtual instruments (VIs). The development process includes considering the motion of the satellite in a user-defined orbit, taking into account various parameters. SubVIs are used to simplify program creation, improve code readability and enable element reuse. To construct one orbit the number of iterations in the loop is calculated, which is the rounded value of the orbital rotation period divided by the time difference between the calculated sub-satellite points. The smaller the value of the time difference is, the more accurate the trajectory will be. Constructing a trajectory with a larger number of revolutions requires more time. For performing the energy calculation, the antenna pattern (AP) is calculated, and a satellite trajectory is constructed with the cross-section of the antenna pattern on Earth. The developed model allows evaluation of the satellite trajectory for a given number of revolutions around the Earth and conducting energy potential calculations for a specified location of the Earth station. The results can be used for building algorithms for adaptive control of parameters in satellite radio links.

Published: September 2024

As a part of the work on the research and development of information technology for converting archival drawing, design and technological documentation into an electronic model of a product, there is often a need to create a data storage and management system, that will allow storing and processing simultaneously all types of geometric and graphic data present on the various stages of the product life cycle. The capabilities of traditional GGI storage methods have limitations, which makes it difficult to work with large volumes of data and complicates the process of accessing the necessary elements. The goal of this article is to develop a database with high performance, reliability and flexibility to meet modern industry requirements. The current problem of developing a database for efficient storage and management of geological data, presented in the form of two-dimensional drawings and three-dimensional models is discussed. Proposed database architecture includes a central storage of graphical data and auxiliary modules for loading, processing, searching and visualizing information. Structures for efficiently storing information about drawing objects and components of 3D models, as well as various methods of indexing and searching for spatial data, such as quadtrees, spatial indexes and others, are considered. Proposed approaches are a promising direction for creating modern systems for storing and analyzing geometric data, which are in demand in many areas using modern computeraided design systems. The implementation of the described solutions will increase the speed of processing spatial information and improve the characteristics of systems for working with drawings and three-dimensional models.
METHODOLOGY OF ACCOUNTING FOR ILLEGAL POLYGONS AS ADDITIONAL CONDITIONS FOR OPTIMIZATION SYNTHESIS OF SCHEMES OF INDUSTRIAL ENTERPRISES’ MASTER PLOT PLANS
Authors: Zuga I. M. , Khomchenko V. G.
Published: September 2024

The paper proposes a methodology of accounting for illegal polygons in the process of computer-aided design of optimal layouts of production and other facilities on the territory designated for an industrial enterprise. A linear piecewise continuous approximation of an arbitrary contour of illegal polygons is used. The location of the contour of the base of objects in an illegal polygon is established based on the analysis of predicates of four types, three of which demonstrate the location of the vertices of objects relative to straight lines containing approximating segments, and one – the location of the object relative to the unacceptable area of the illegal polygon. The last of the mentioned predicates is implemented by the "ray" method. Using the mathematical apparatus of R-functions, 16 typical mutual positions of the contours of facilities foundations and approximating segments of polygons were discovered including facilities both inside and outside the closed polygon. Logical functions to identify the established typical mutual positions of facilities and illegal polygons are obtained, as well as analytical expressions for calculating partial and resultant penalty functions reflecting the degree of violation by facilities of the boundaries of illegal polygons. To correctly select the analytical expression of the penalty function from the proposed set, parameters are introduced that characterize the location of the approximating segments relative to the invalid area of the illegal polygon, relative to objects and coordinate axes. The numerical experiment performed using the gradient algorithm showed the adequacy of the proposed approach and the steady return of the facilities to the permissible area, which confirmed the possibility of applying the developed methodology in the computer-aided design.

Authors: Konovalov V. A.
Published: September 2024

The material of the article is a continuation of the study of the methodology for classifying typologies of money laundering and terrorist financing risks in big data from a variety of data sources of organizational systems. The process of counteraction is investigated. Theoretically substantiated and synthesized functional and conceptual models of this process. When synthesizing a functional model of counteraction, the IDEF0 methodology was used. In the course of modeling, it was found that such counteraction models are distinguished by the need to verify the signs of illegal economic activity of organizational systems. When analyzing the conceptual model of the counteraction process, it was found that credit institutions are not interested in countering the risks of laundering proceeds from crime that arise in the course of their commercial activities. The conceptual model of the process of combating money laundering and the financing of terrorism showed the need for a partial structural reorganization of tis process and the system that implements it. It is necessary to carry out a structural reorganization of the national countermeasure system with the organization of access to a variety of new data sources that reveal the nature of the activities of controlled organizational systems, as well as to control credit institutions, to introduce a distributed countermeasure system, which consists of remotely controlled software algorithms. A typology of a separate risk of money laundering in credit organizations is synthesized as an example illustrating the lack of interest of these organizations in detecting risks in their commercial activities. The analysis of the reasons for the omission of this typology by various participants in the counteraction, discussed in the conceptual model, is carried out. It is concluded that there is a need for conceptual changes in the system of combating money laundering and the financing of terrorism, which will improve the completeness of the classification of typologies of individual risks.

MORPHOLOGICAL SHAPE AND IMAGE COMPARISON BASED ON SIMPLICITY THEORY AND POINT COVERINGS MODEL
Authors: Vizilter Yu. V. , Brianskiy S. A.
Published: September 2024

This article is devoted to development of new models and techniques for morphological image analysis and the simplicity theory. A new method for image shape comparison and description via the point coverings model is proposed. It is demonstrated that within the framework of point covering models the concept of projection to mosaic shape and even the concept of mosaic shape are not required for calculation of the morphological correlation coefficients for any morphological models described by the patterns of simplicity distribution on the image frame. Based on these non-strict similarity models, the projective morphology for non-strict shapes is proposed. In the framework of such morpology all shape description tools from original Pyt’ev morphology can be defined: mosaic frame coveraging (analogous to mosaic frame splitting), relational model based on non-strict similarity relations, class of images of the same non-strict shape, morphological operator as a projector to the class of non-strict shapes. The difference between the proposed and original Pyt’ev’s versions of morphological analysis is that the image class is no longer a linear subspace in the image space.

GENERATION OF A PARAMETRIC MODEL OF A THREE-DIMENSIONAL OBJECT ACCORDING TO AN ELECTRONIC TECHNICAL DRAWING
Authors: Smychek M. M. , Tyurina V. A.
Published: September 2024

The article describes an algorithm for calculating the parametric number of a three-dimensional composite geometric figure according to an electronic technical drawing, which allows to automate the process of generating an electronic parametric model of the object. This algorithm is relevant for use in geometric modeling systems that use variation (or dimensional) parameterization. The described approach allows to optimize the process of creating a parametric model of a product during interaction with the geometric modeling system and is the basis for developing an algorithm for automated model generation. When creating the parametric model of the object, the most important task is to quickly and correctly set the independent parameters responsible for the design of the designed object, therefore the development of algorithms that can replace a person in this process releases time costs for design and allows to minimize the number of non-optimal and false solutions. Thus, as a result of the combination of algorithms for recognition and analysis of geometric information on the technical drawing, the user gets the opportunity to work with the finished parametric model of the object with all its advantages. A huge advantage is the possibility of quick editing and modification by managing the final set of independent variables and the possibility of establishing mathematical ties between these variables. In this regard, the work of the designer goes to a new level, allowing him to allocate time and intellectual resources more rationally and efficiently. In the article, the main task of the study is to highlight the elements of the structure and their connections from the technical drawing, since the process of calculating the parametric number of the modeled composite figure is based on the identification and summation of the parametric numbers of non-derivative and composite figures that make up the structure of the general figure.
METHODS FOR SYNTHESIZING SIGNS OF THE RISKS OF LAUNDERING PROCEEDS FROM CRIME
Authors: Konovalov V. A.
Published: September 2024

Methods for synthesizing risk features are being explored in the interest of creating a methodology for classifying MLB and TF risk typologies in big data from multiple data sources of organizational systems. A new space of risk features is investigated, consisting of words and their morphisms, represented by diagrams of Markov occurrences of words in each other, obtained by synthesis using the N-scheme of the Markov algorithm. Typologies of individual risks of money laundering and terrorist financing are considered as separate risk knowledge. When considering knowledge, it is taken into account that they are of a changeable nature, therefore, they must be reviewed and refined in the process of counteraction. Knowledge is treated with the assumption that some of them are quite far apart when viewed through the structure of the categories they form. The study shows synthesized methods for excluding and suspending risk features in a promising risk classifier. The method for excluding risk features from a promising classifier is considered and illustrated by an example of a valid feature in the classifier of the Central Bank of the Russian Federation, introduced by the Bank of Russia Regulation No. 375-P dated March 2, 2012 (as amended on October 20, 2020), which requires exclusion from it. The way to suspend the action of a risk attribute, without excluding it from a promising classifier, is presented in the study, using the example of a risk from the classifier of the Central Bank of the Russian Federation. Examples of refinement of a risk attribute, without excluding it from the classifier and synthesizing a risk typology for it, are presented in the form of categorical formulas with restrictions on some morphism parameters. The presented methods of excluding and suspending the action of risk features in the risk classifier allow a wider use of the acquired knowledge, which is understood as typologies of individual risks, and take into account the changing nature of this knowledge, understood as a specification of knowledge.

The problem of constructing an algorithm for recognizing and filtering a continuous-valued Markov process measured in a mixture with random additive and multiplicative interference under conditions of random information interruptions is considered. The Bayes principle and the well-known two-stage filtering method “forecast-correction” are applied, supplemented by procedures for identifying the number of the structure, in which the system is located in the current and next time intervals. At the forecast stage, identification is based on calculating the probabilities of the future state of the system based on a priori information about the probabilities of its transitions from structure to structure, as well as on the current values of estimates of these probabilities. At the correction stage, identification is based on the use of probability prediction results and a priori known information about the reliability of the information of the system status indicator. In addition, the values of the probability densities of the measuring information in each structure are used, the expressions for which are obtained on the basis of a priori known laws of distribution of additive and multiplicative interference, as well as the predicted probability density of the Markov process in each structure at the next step of calculations. To obtain a practically realizable algorithm, expressions for the predicted and a posteriori densities of the Markov process probabilities are obtained based on their approximation by the probability density of the gamma distribution, completely determined by the first two initial moments. This made it possible to obtain a closed system of recurrent equations for estimating the probability of information interruption, mathematical expectations and variances of the Markov process in each structure.

The possibilities of using digital model visualization in the educational process of higher education in the training of engineers are demonstrated. Based on the assembly drawing, students are required to perform a number of tasks as a part of the educational construction bureau. First of all, it is necessary to develop a digital model of a technical product in size, distribute the details of the assembly unit among the students of the group. Further, a specialist appointed by the constructor engineer carries out the assembly and develops engineering documentation. The software engineer includes variables in the model at the level of different details and the finished assembly, which allows you to change the construction of the product in the dialog box mode. The associativity of the model and the drawing sets the automatic updating of the entire construction. Visualization of the digital model allows to customize the appearance of the assembly, apply materials, textures, lighting effects and shadows. Animation is being developed by a student from the construction bureau to understand the operation of the mechanism. Another option for demonstrating the created digital model is set using the assembly and disassembly script of the product. The presentation of the project is carried out in a virtual reality system. The engineering of the product is carried out in the T-FLEX CAD, which is part of the Russian information PLM system. The analysis of the content and effectiveness of educational activities on 3D visualization of digital models performed during group work actualizes a group of traditional knowledge, skills and abilities required by a qualified engineer and forms competencies of an advanced, innovative nature related to both the professional and the communication.

Currently, Russia is moving towards automating the collection of information from metering devices for heat, gas, water, electricity, etc. Technologies are being developed that allow the transmission of resource consumption data via various communication channels, both wired and over-the-air. There are already devices and devices that allow transmitting readings of electricity metering devices over existing wired communication networks and this issue is being resolved at the legislative level, Federal Law No. 522-FZ of 07/01/2020 has been adopted. The basis for the research is to save time and effort in obtaining the necessary information to account for electricity readings from substations, increase the speed of decision-making, and be able to predict the situation with big data to identify abnormal values and eliminate them (for example, identified data from electricity meters will reduce the time labor of metering operators and economic losses of an energy supply company). The article proposes hardware and software methods for detecting data on electricity losses based on the use of artificial neural network algorithms and allowing to detect inconsistencies in commercial data readings of electric meters, which will reduce the commercial component of electricity losses. A verification calculation of an artificial neural network was performed for inconsistencies in the data on the transmitted electricity. The design of a receiving and transmitting digital module for remote data recording has been carried out, as well as the development of an automated system designed for remote collection, processing, storage and transmission of information on energy consumption and balance. The developed automated information and measurement system for remote data collection and transmission was tested at the manufacturer of smart electric energy meters with a radio channel.
