Item type: Item , IMPACT OF ROAD INFRASTRUCTURE ON TRAFFIC SAFETY IN KASHKADARYA REGION(https:// journalss.org/index.php/luch, 2026-01-28) Karimov Akbar Akbarovich; Narzullayev Abror Ahror ogliRoad traffic safety is a critical issue in urban areas, where increasing traffic volumes and complex road network structures contribute to a higher risk of traffic accidents. This study investigates the impact of road infrastructure conditions on traffic safety in the Kashkadarya region, using Karshi city as a case study. The research focuses on street intersection density as a key infrastructural indicator influencing traffic safety outcomes. Open-source road network data were extracted from OpenStreetMap and analyzed using Geographic Information System tools. A grid-based spatial approach was applied to calculate intersection density across the study area, and traffic accident statistics were integrated to assess safety performance. A relative risk index was used to quantify the relationship between intersection density and traffic accident occurrence. The results reveal a clear spatial association between high intersection density and elevated traffic risk levels, particularly in central and highly trafficked zones. The findings highlight the importance of incorporating spatial infrastructure indicators into traffic safety assessment and urban transport planning to support data-driven decision-making and targeted safety interventions.Item type: Item , TRAFFIC SAFETY ENHANCEMENT USING INTELLIGENT TRANSPORT SYSTEMS IN KARSHI CITY(https:// journalss.org/index.php/luch, 2026) Karimov Akbar Akbarovich; Fayzullayev Nurilla Sirojiddin ogliTraffic safety remains a critical challenge in urban areas due to increasing traffic volumes and complex traffic conditions. This study investigates the potential of Intelligent Transport Systems to enhance traffic safety through improved speed management, real-time traffic monitoring, and data-driven traffic control strategies.

Выполнен анализ процессов взаимодей ствия рабочего органа с почвой, сопровождающихся локализованным динамическим воздей ствием, перераспределением контактных напряжений и разрушением почвенных агрегатов. Проведены полевые экспериментальные исследования на светлых суглинистых почвах юж ных регионов Узбекистана при влажности 10–13 %, плотности сложения 1,3 г/см³ и сопротив лении проникновению около 1,7 МПа. Для оценки эффективности работы экспериментального катка использовались показа тели степени крошения почвы, тягового сопротивления и удельной энергоёмкости обработки. Исследования проводились с применением тензометрической системы измерений и методо логии поверхности отклика (RSM). Установлено, что использование упругих стержневых эле ментов обеспечивает повышение степени крошения почвы на 12–18 % и снижение тягового сопротивления примерно на 9 % по сравнению с традиционными жёсткими катками. Наиболее эффективный режим работы достигался при диаметре стержней 4 мм, количе стве стержней 65–70, рабочей ширине около 0,6 м, вертикальной нагрузке порядка 0,87 кН и рабочей скорости 8–9 км/ч. Полученные результаты подтверждают перспективность примене ния упругих рабочих органов для повышения энергетической эффективности и качества пред посевной обработки почвы.Item type: Item , ОЦЕНКА ЭНЕРГЕТИЧЕСКОГО ПОТЕНЦИАЛА РЕКУПЕРАЦИИ ТЕПЛОВОЙ ЭНЕРГИИ ВЫХЛОПНЫХ ГАЗОВ АВТОМОБИЛЯ CHEVROLET COBALT В КЛИМАТИЧЕСКИХ УСЛОВИЯХ РЕСПУБЛИКИ УЗБЕКИСТАН(UNIVERSUM: ТЕХНИЧЕСКИЕ НАУКИ, 2026-06-28) Мансуров Ботырхан Фарход угли; Киямов Асрор ЗиядуллаевичПовышение энергетической эффективности автомобильного транспорта является одной из актуальных задач современного автомобилестроения.

The aim of this study was to substantiate the design and operating parameters of a skidtype leveler–compactor integrated into a combined machine for one-pass pre-sowing soil preparation of rainfed land with the simultaneous laying of drip irrigation hoses and plastic film for melon crops. The research combined theoretical modeling of soil–tool interaction with single-factor and multifactor field experiments and a two-year agronomic evaluation under farmer field conditions. The optimal parameter ranges were 24.0–26.0◦ for the lower compacting element, 151–155◦ for the upper leveling part, and 24.3–27.0 cm for the tool height. Under these conditions, the proposed system ensured a soil fraction < 25 mm of 87.2%, surface irregularities of 1.34 cm, and reduced fuel consumption, from 38.6 to 26.3 kg ha−1, compared with the conventional method. The field emergence increased to 91.6%, the total yield reached 50.7 t ha−1, and the water use efficiency increased to 17.4–18.9 kg m−3. The results demonstrate that optimization of the leveler–compactor significantly improves strip quality, agronomic performance, and resource use efficiency in melon production under plastic film.Item type: Item , DEVELOPMENT OF MODELS OF RECRESSION OF DEFATORY STATES OF COMPONENTS AS A RESULT OF EXTERNAL LOADS OF BELT CONVEYOR DRUMS(International Agency for Development of Culture,Education and Science United Kingdom USA Soldiers Field Boston. 2026., 2026-03-28) Jumaev Akbarjon Sayfullaevich; Salimov Giyosiddin Ilyosovich; To‘xtamurod Fayziyev Zulfiqor o‘g‘liThe article discusses developing and implementing a regression model to calculate various damages to their components due to different external loads from single-belt conveyor drums from vehicles used in mining enterprises.

M. Mamatov; H. A. Ravshanov; V. B. Ortikov; D. Sh. Chuyanov; M. D. BurievAnalyzed are the conditions and specific features of primary soil tillage under irrigated farming systems of Uzbekistan, taking into account soil and climatic characteristics and agrotechnical requirements. Investigated is the structural design of a two-tier plow intended for double-depth plowing, including existing technical solutions applied in agricultural practice. Revealed is the influence of insufficient soil loosening and increased energy consumption on the operational efficiency of conventional two-tier plows. Studied is the interaction between the upper and lower plow bodies and additional loosening devices of various designs during the soil tillage process. Determined is an experimental comparison of three types of loosening tools-chisel-type, sweep-type, and an inclined-shank loosener of the paraplow type-based on soil clod fragmentation and draft resistance indicators. Established is the quantitative effect of the loosener design on the degree of soil loosening and the draft resistance of the implement. Substantiated is the application of an inclined-shank loosener as a rational component of the two-tier plow design that ensures the required soil treatment quality while reducing energy consumption. Presented is a description of the experimental setup and research methodology based on the principles of experimental design theory and standard testing procedures.Item type: Item , Geometry-Optimized Strip Tillage for Improving Soil Physical Quality and Hydraulic Function in Semi-Arid Vineyards(Agriculture, 2026-03-28) Yurii Syromiatnykov; Farmon Mamatov; Antonina Sholoiko; Ivan Galych; Dilmurod Irgashev; Khamrokul Ravshanov; Nargiza Ravshanova; Gayrat Ergashov; Yarash Rajabov; Feruza Mukumova; Alisher Suyunov; Bektosh AlievSoil compaction and reduced infiltration capacity are critical constraints limiting soil physical quality and hydraulic functioning in semi-arid vineyard systems subjected to repeated machinery traffic. This study aimed to develop and evaluate a geometry-optimized strip tillage tool designed to improve structural functionality within the compacted root zone while minimizing inter-row disturbance. A U-shaped working body configuration, consisting of two oppositely inclined shanks and a central chisel, was theoretically substantiated and optimized using multifactor analysis. Field experiments were conducted to assess changes in penetration resistance, bulk density, and infiltration rate within the 20–40 cm soil layer under semi-arid conditions. The optimized geometry significantly reduced penetration resistance and bulk density in the trafficked strip, indicating alleviation of mechanical impedance and improved root-relevant physical conditions. Infiltration capacity increased after treatment, indicating enhanced hydraulic continuity within the root zone. Unlike full-width subsoiling, the localized strip intervention preserved inter-row soil stability and limited unnecessary disturbance, which is consistent with conservation-oriented soil management. The results indicate that geometry-optimized strip tillage is associated with improved soil physical quality and hydraulic function within compacted vineyard strips. The operational applicability of the developed implement may also depend on vineyard layout and terrain conditions. The prototype tool was tested under conditions representative of vineyards with standard row spacing and relatively moderate slopes typical for the experimental site. In vineyards with very narrow row spacing, steep slopes, or highly heterogeneous soil conditions, adjustments in working width, shank spacing, or tractor–implement configuration may be required. Future studies should therefore investigate the performance of the optimized geometry under contrasting vineyard configurations, including steep hillside vineyards and high-density planting systems. By linking implement design to quantitative soil structural and hydraulic indicators, this study contributes to the development of vineyard soil management practices for semi-arid perennial cropping systems.Item type: Item , Independent Engineering Transfer After Traceable Generative-AI-Assisted Learning: A Six-University Controlled Trial with Deterministic Cluster Allocation in Agricultural Engineering Education(applied sciences, 2026-09-09) Yurii Syromiatnykov; Farmon Mamatov; Khurshid Chuyanov; Zafar Batirov; Dustmurod Chuyanov; Makhmatmurod Shomirzaev; Dilrabo Shadieva; Khurshid Ilkhomov; Gulandom Jo’rayeva; Mirshohid EgamovGenerative artificial intelligence (GenAI) can support engineering problem solving, but whether AI-assisted practice transfers to independent performance after the tool is removed remains unclear. This multicentre controlled trial evaluated a traceable five-stage GenAI assisted learning configuration in agricultural engineering education. Twenty-eight second and third-year classes from six universities in Uzbekistan were assigned within nine teacher blocks by deterministic constrained minimization to GenAI (14 classes) or structured active control (14 classes) groups. Both groups completed the same 16-week module, tasks, software, contact time, feedback, and verification requirements. They differed in the source and adaptivity of a provisional alternative used after an independent attempt: bounded adaptive GenAI dialogue versus a version-controlled curated alternative. The full assigned cohort included 656 students; likelihood-based available-outcome analyses included 641 im mediate and 589 delayed outcomes. Kenward–Roger analyses estimated an adjusted imme diate difference of 2.78 points (95% confidence interval (CI) [2.02, 3.55]; p < 0.001; model basedd=0.72)andadelayeddifferenceof2.34points(95%CI[1.54, 3.14]; p<0.001; d = 0.51). The results show a positive adjusted association for the evaluated traceable instruc tional configuration, but deterministic post-baseline allocation limits causal interpretation.Item type: Item , Results of Field Tests of a Cultivator With a Ribbed Disc-Type Working Body for Soil Tillage in Cotton Row Spacings Prior to Winter Wheat Sowing(International Journal of Advanced Research in Science, Engineering and Technology, 2026-07-28) Mamadiyorov Obid TursunovichThis article presents a new cultivation technology for soil tillage in cotton row spacings prior to winter wheat sowing.
