Development Of Deep Learning Models And Algorithms For Language Processing In Uzbek
Full text linkThis article focuses on the development of deep learning models and algorithms specifically designed for Uzbek language processing within the IT field. A comprehensive approach involving data collection, preprocessing, model selection, and evaluation was employed. Experiments with RNN, LSTM, and transformer-based models like BERT and GPT were conducted, with transformer models yielding superior results. Key challenges included limited datasets and the complex morphological structure of Uzbek. The findings suggest that fine-tuned transformer models, especially with language-specific preprocessing, can significantly improve performance in language understanding tasks for low-resource language
Ensuring the reliability of voltage and frequency control in modern power grids
Full text linkThis article extensively covers the issues of stable and reliable voltage and frequency parameter control in modern power systems. With the widespread use of renewable energy sources in the power sector, such as solar and wind power plants, hybrid systems integrated with traditional centralized power grids are emerging. One of the main problems in such systems is the effective elimination of voltage and frequency disturbances caused by variability in production due to natural factors. The article notes that photovoltaic panels can cause short-term but significant voltage fluctuations due to rapid changes in light flux. This can reduce the reliability of equipment in the grid and the quality of supply for users. Therefore, it is necessary to implement highly accurate automated control systems in power grid

This method can be considered an environmentally friendly and pesticide-free alternative for pest control
Research Of The Temperature Regime Of The Heliopyrolysis Process
Full text linkThe article analyzes the temperature regime in the reactor of the pyrolysis device and the saving of thermal energy consumed for the specific needs of the device, as well as the thermal technical indicators of the device. The article also proposes a heliopyrolysis system with a solar concentrator to provide heat to the pyrolysis reactor. As a result of the use of a solar concentrator in this type of pyrolysis device, it is possible to obtain a temperature of 400-700 ℃. As a result, it allows reducing the specific energy consumption for the pyrolysis process by up to 30%. The objectives of this computational and theoretical research on the heliopyrolysis process are mainly aimed at an approximate assessment of their thermal efficiency, taking into account the degree of optimization of thermal technical parameter
Solving Problems in the Application and Development of Aviation Decoy Targets
Full text linkModern air combat environments are becoming increasingly hostile due to rapid advancements in radar, infrared (IR), and multi-spectral detection technologies. As a result, aviation decoy targets have become indispensable elements of aircraft survivability strategies. These devices, which include both towed and expendable variants, are designed to mislead enemy detection systems and intercept incoming threats. However, their operational performance is often limited by technical and tactical challenges, such as insufficient signal fidelity, limited adaptability to evolving threats, and integration issues with on-board electronic warfare (EW) systems. It presents a comprehensive examination of the challenges associated with the development and deployment of aviation decoy targets. A multi-layered research methodology involving system-level engineering analysis, digital modeling, and review of defense field data is employed to assess current decoy technologies. Key problems, such as reduced efficiency in harsh environmental conditions and vulnerability to advanced missile guidance systems, are identified and addressed. The findings suggest that significant improvements in decoy performance can be achieved through the use of adaptive emission algorithms, and modular hardware designs that allow better integration with the host aircraft’s EW suite. Case studies and simulation results support the proposed enhancements, demonstrating a measurable increase in aircraft survivability rates in complex threat environments. It concludes with a roadmap for future decoy development, emphasizing the need for collaborative international research, rapid prototyping, and real-time threat adaptation. These improvements are vital for maintaining air superiority and protecting high-value aerial assets in contested airspace

Development Of Technological Schemes For Transporting Rock Mass And Management Of The Working Area Of A Deep Quarry
Full text linkThe operating conditions of modern industrial vehicles are determined by the increasing depth of mining operations. This trend results in the predominant use of vehicles (over 60%) as assembly units, concentrating vehicle traffic in the working area of deep quarries with their limited space of the Muruntau deep quarry is characterized by a high concentration of traffic, heterogeneity of the transported rock mass, and instability of key parameters. During a shift, 10-15 working faces and 5-10 transfer points are in operation, forming over 100 routes with an average length of 3.73 km. The maximum freight traffic intensity on individual routes reaches over 35,000 m³ of rock mass per shift. The share of face roads along the traffic routes is 15-30%. Up to 80% of the roads have a service life of up to one year. The complexity of operating conditions is exacerbated by the high concentration of mining equipment and minimal excavation space
