COMPREHENSIVE LANDSLIDE HAZARD ASSESSMENT IN KYRGYZSTAN BASED ON SATELLITE DATA AND MACHINE LEARNING APPROACHES
type: item
description: This study examines the application of geographic information systems (GIS) and machine learning methods for landslide susceptibility mapping in the southern regions of Kyrgyzstan. The analysis is based on the SRTM digital elevation model and statistical data on previously recorded landslides. Morphometric terrain characteristics, including slope, aspect, curvature, and the Topographic Wetness Index (TWI), were derived and used as input features for model training. A Random Forest algorithm was employed to assess landslide susceptibility. As a result, a landslide probability map was generated, enabling the identification of the most vulnerable and potentially hazardous areas within the study region. The results confirm the effectiveness of integrating geospatial analysis and machine learning techniques for regional-scale natural hazard assessment.

APPLICATION OF FOURIER TRANSFORM FOR IDENTIFYING SEASONAL FLUCTUATIONS IN CONSUMER DEMAND IN RETAIL TRADE
type: item
description: This article examines the application of the Fourier transform for analyzing seasonal fluctuations in consumer demand in retail trade. Seasonality is one of the key factors affecting sales dynamics across various product categories. Traditional time series analysis methods allow researchers to identify trends and seasonal components; however, their effectiveness may decrease when demand patterns contain complex periodic dependencies. The Fourier transform makes it possible to decompose a sales time series into a set of harmonic components and determine dominant frequencies that characterize consumer purchasing behavior. The paper presents the theoretical foundations of the method, an analysis algorithm, and an example of its application to retail sales data. The results demonstrate that spectral analysis can effectively identify weekly, monthly, and annual demand cycles, thereby improving forecasting accuracy and inventory management efficiency. The study confirms the potential of Fourier-based methods as a tool for demand forecasting and decision support in modern retail management.

EXPERIENCE IN DEVELOPING A GEOINFORMATION SYSTEM FOR MUDFLOW MONITORING FOR THE MINISTRY OF EMERCOM OF KYRGYZSTAN: EIGHT APPLIED PROBLEMS OF SPATIAL ANALYSIS
type: item
description: This article summarizes the experience of developing a geoinformation system for mudflow monitoring in the Kyrgyz Republic. Eight applied spatial analysis problems that arose during the design process and the proposed technical solutions are considered. Particular attention is paid to the results of load testing: it is shown that zonal statistics for metered streams without appropriate optimizations leads to an 18% failure rate under load and requires two consecutive optimization measures to reduce this rate to zero. It was also found that transferring heat map calculation to the client (browser) provides higher performance compared to server-side calculations with comparable hardware resources.

AN INTELLIGENT DIGITAL TWIN OF THE MODEL FOR THE PRODUCTION OF DRY BUILDING MIXES BASED ON MAN-MADE WASTE
type: item
description: The article discusses the development of an intelligent digital twin for the production of dry building mixes using man-made waste from metallurgy and energy based on artificial intelligence technologies. The relevance of the study lies in the need to increase the resource and environmental efficiency of dry mix production, reduce the proportion of clinker materials, and introduce digital methods of process control in conditions of variability in raw material properties. The developed model is implemented as a hybrid digital twin that combines discrete event modeling of a production line and an intelligent subsystem for predicting product quality. Process control is formalized using a finite state machine that covers all key stages of production: component dosing, mixing, unloading, packaging, and batch archiving. Artificial intelligence is used to evaluate the physico-mechanical properties of a mixture (strength, density, workability) based on the composition of the formulation and the proportion of man-made components. Quantitative results confirming the effectiveness of the proposed approach were obtained during the simulation. It has been established that the proportion of man-made waste in the composition of dry mixtures can reach 40-50% without a critical decrease in the predicted quality indicators. The reduction in cement consumption is up to 30%, while the estimated capacity of the line reaches 15-20 t/h. The model provides automatic accounting of slag and ash consumption by batch, shift, and month, as well as dynamic assessment of the carbon footprint of products. The scientific novelty of the work lies in the integration of simulation modeling of the production cycle with the AI subsystem for assessing quality and environmental performance within a single digital model. The practical significance is determined by the possibility of using the developed model as a digital twin of the real production of dry building mixes, a tool for optimizing formulations,…

DESIGN AND PERFORMANCE EVALUATION OF A SCALABLE E-PETITION SYSTEM: A MONOLITHIC ARCHITECTURE APPROACH FOR LOCALIZED E-DEMOCRACY
type: item
description: In the digital age, an electronic petition is one way for citizens to express their opinions, complaints, or proposals on matters of interest or public service. In fact, through international websites such as Change.org and Avaaz.org, etc. It is not uncommon for them to fail to meet the needs of each country, particularly when flexibility, transparency, and data protection are required. Here, we introduce the design and evaluation of an e-petition system for local citizens. Our proposed system is implemented using the Django framework and a PostgreSQL database. Our proposed system utilizes the monolithic approach and attempts to maintain the equilibrium between ease of use, reliability, and security aspects required in a local e-petition system with the adoption of necessary moderation features to prevent misbehaviors (abuses) during the gathering of local citizen votes, measures to avoid any types of possible abuse from non-local users namely fraud and additional aspects such as data protection for the citizens.

DESIGNING A LOCAL INFORMATION SYSTEM FOR ORGANIZING AND CONDUCTING SOCIOLOGICAL SURVEYS.
type: item
description: The objective and purpose of this project stem from the need to integrate all stages of sociological research into a single digital environment, since in current practice, the preparation of questionnaires and scales, as well as data collection and coordination, are typically carried out using various methods and, at times, different tools. SurveyOps Studio is implemented as a local web application based on Node.js, HTML, CSS, and JavaScript, and includes a feature for persistent data storage in JSON format. Using SurveyOps Studio with all its features is entirely possible within a single application, even with relatively simple software and hardware configuration. Thus, it is an ideal option for introducing new methodologies into an educational program, developing new research concepts within an organization, or testing sociological research methodologies within a project.

TAKING INTO ACCOUNT CRACKING WHEN ASSESSING THE STRESS-STRAIN STATE OF A ROCK BLOCK
type: item
description: This paper examines the stress-strain state (SSS) of a rock block, taking into account fracturing, using the Plaxis software suite. The author examines various approaches to modeling fractures in the rock mass, focusing on the finite element method and Goodman contact element theory. A numerical experiment established the dependence of nodal point displacements and compressive stress concentrations at the crack tip on the crack's inclination relative to gravity. It was found that certain angles of incidence trigger the most dangerous deformation characteristics, which contribute to macroscopic fracture and collapse of the block.

THE NATURE OF DISTRIBUTION OF ACCUMULATED ELASTIC DEFORMATION ENERGY IN THE ZONE OF MOUNTAIN SLOPE BENCHES
type: item
description: This paper examines the quantitative and qualitative parameters of accumulated elastic energy in a mountain slope with benches to identify potential failure zones. Using analytical modeling in Mathcad, two loading scenarios were considered: the effect of gravitational forces alone and their combined effect with horizontal tectonic compression. Using Muskhelishvili functions, stress components were calculated, as well as the specific energies of volume and shape change for an elementary volume of the slope. The obtained results enable differentiated prediction of slope stability in bench-to-bench contact zones.

PROSPECTS FOR THE USE OF ECO-CLEAN COAL-WATER FUEL IN KYRGYZSTAN
type: item
description: This article analyzes the prospects for implementing coal-water fuel (CWF) production and combustion technology in Kyrgyzstan as an alternative to expensive gas and fuel oil. The author emphasizes that the republic possesses colossal brown coal reserves (approximately 28.3 billion tons), but its traditional use is hampered by its high tendency to fragment (up to 50% of the output is converted into unused fines) and the environmental damage it causes when burned. Switching to CWF allows this waste to be converted into a highly efficient and safe energy resource.

CONSTRUCTION OF THE TRANSITION MATRIX OF A DISCRETE CONTROL SYSTEM
type: item
description: This article discusses a method for constructing a transition matrix for discrete control systems, a key step in solving difference equations. The authors propose using the Cayley-Hamilton theorem to efficiently calculate the matrix degree when discrete time assumes large values. The method is based on representing the transition matrix as a polynomial in a matrix of degree at most n-1, where the coefficients are determined through the system's eigenvalues.

PREPARATION OF COMPUTATIONAL ACCELEROGRAMS FOR MODELING SEISMIC EFFECTS ON EARTH DAMS IN THE FLAC PROGRAM
type: item
description: This article describes a methodology for preparing accelerograms for dynamic seismic analysis of earth dams using the FLAC program. The author provides a detailed analysis of the process of transforming initial acceleration records into boundary conditions (velocities and stresses), taking into account the free-surface amplitude doubling effect. Using the example of the Suusamyr earthquake (1992), the author demonstrates the steps of scaling peak accelerations to 0.4g, frequency filtering (to 10 Hz), and adjusting the zero-displacement line for accurate modeling.

MINIMUM ENERGY CONTROL IN A DISCRETE OPTIMAL CONTROL PROBLEM
type: item
description: This article describes a method for solving a discrete optimal control problem for stationary systems with a small step size. The authors propose an algorithm for dividing the original system into two subsystems of lower order, which simplifies the search for a control that minimizes energy costs. The possibility of finding the optimal control and corresponding trajectories by solving matrix equations of the Riccati and Lyapunov types is demonstrated.

ABOUT BASES AND PRE-BASES OF MAPPINGS
type: item
description: This article examines set-theoretic and topological characteristics of continuous mappings, extending the classical concepts of bases and networks of spaces to the case of mappings. The author introduces definitions of prenets and prebases of a mapping, proves criteria for their existence, and explores cardinal invariants such as the character and weight of a mapping. It is established that the first and second countability axioms for mappings are hereditary properties, and an analogue of the Alexandrov-Urysohn theorem on the cardinality of a base is proved.
