Abstract:
The paper indicates scientifically substantiated continuous, year-round use of irrigated lands in Surkhan-Sherabad valley, southern zone of Uzbekistan. In research, scientifically substantiated production agrotechnology of crops in one agricultural system were investigated, where the crops were grown as a main crop, summer crop and after winter wheat and barley harvesting. The following yields were obtained: winter wheat variety “Chillaki” 4.89 to 5.65 t ha-1, barley variety “Bolgali” 5.44 to 6.03 t ha-1, after winter wheat and barley harvesting: maize variety “Uzbekistan-306 AMB” 4.60 to 5.28 t ha-1 grain, variety “Nart” 4.27 to 5.19 t ha-1 grain, cabbage variety “Sharkiya” 44.8 to 53.5 t ha-1, variety “Uzbekistan-133” 45.7 to 54.0 t ha-1, upland cotton varieties “Bukhara-6” and “Bukhara-8” 2.85 to 3.21 t ha-1 and 2.89 to 3.24 t ha-1 respectively.

DEVELOPMENT OF LINEAR MATHEMATICAL MODELS OF THE TECHNOLOGICAL PROCESS OF SEED CRUSHING
Author: Yusupov Firnafas, Kim Tatyana Yurevna, Nurmetova Bonuraxon Baxromovna, Xojibayev Jonibek Maxmudjonovich
Abstract:
The simplified statistical linear model of the object under study is developed on the basis of experimental and statistical studies of the technological process of crushing cottonseed in an oil extraction plant using the experimental design method. The analysis includes the homogeneity of dispersion, the significance of the coefficients of the linear model, and the adequacy of the resulting model.
MATHEMATICAL MODELS OF MULTI-COORDINATE ELECTROMECHATRONIC SYSTEMS OF INTELLECTUAL ROBOTS
Author: Nazarov Hayriddin Nuriddinovich, Temurbek Rakhimov Omonboyevich
Abstract:
In the article, the mathematical description of the mechatronic module in intelligent robots and robotic systems is observed. To display the structure of mechatronic modules, which consist of interrelated different electrical, magnetic, and mechatronic components, mathematical models are designed using multiplication theory based on relations and visualizing lines and points. An analytical explanation of the mechatronic model in intelligent robots is provided.
DEVELOPMENT OF INHIBITOR COMPOSITION OF CORROSION FOR PROTECTION OF STEEL ARMATURE
Author: Jumaniyazova Dilnoza Maxsudovna, Zakirov Baxtiyor Sabirjanovich, Jumaniyazov Maxsud Jabbiyevich
Abstract:
For over 150 years, reinforced concrete structures have been used in construction. A long-term study of the durability of reinforced concrete structures in various operating conditions shows that dangerous damages caused by the development of reinforcement corrosion, which pose a threat to public health, are often encountered.
Corrosion of reinforcement is usually caused by exposure to reinforced concrete by atmospheric chemical factors caused by the presence of aggressive components in concrete, such as sulfates, carbonates, and chlorides. Today, in domestic practice, there are over 100 different compositions for inhibiting the corrosion of reinforcing steel. The disadvantages of the existing anticorrosive materials are their high cost and low accessibility, as well as the impossibility of using them to combat multicomponent salt and acid corrosion.
In the conditions of the Aral Sea region, in the production of reinforced concrete products, highly saline water and quartz sand are used, which contain chloride and sulfate salts of calcium, magnesium, and sodium in various amounts (Table 1). With the presence of the listed salts in the composition of reinforced concrete products, steel reinforcement is subjected to severe corrosion.
Therefore, one of the important tasks is the protection of steel reinforcement in concrete products produced in the conditions of the Khorezm region and the Republic of Karakalpakstan.

AN ANALYSIS OF THE WORK OF PASSENGERS TRAINS ON TWOZONE SECTIONS AND THEIR ALERT AUTOMATION
Author: Tokhirov Nosirjon Sobirjon ugli
Abstract:
Company "Uzbekistan railways" has made a great contribution to the safety of passenger traffic. It is expected that passenger trains will have a number of factors affecting the large passenger traffic in the coming days and will be in the future. That is why passenger trains require that the issuance of warnings from workers of the running facilities, electricity, signaling and communications, as well as station attendants at the station by dispatchers, be accurate and error free. This article describes the automation of issuing warnings for trains and trains at two zones.
