Abstract:

Mismatch is one of the main defects of tailor welded blanks(TWB), and leveling technology is a new method which can solve this problem. The structures, force analysis and flange morphology of the leveling mechanism are studied in this paper, and a three-dimensional prototype is designed. The results have practical significance for improving welding quality of TWB.

Abstract:

Precision land leveling must be treated as a precursor technology for improving crop yield, enhancing input-use efficiency and ensuring long-term sustainability of the resources. A field experiment was conducted in Dongola Agricultural Research Farm, Northern State, for two successive seasons to investigate the effect of three type of ploughing; heavy disc harrow (H1), disc plough (H2) and no-ploughing (H3), and three land leveling techniques, Laser (L), Scraper (S) and traditional (T),on wheat production. The experiment was arranged in a strip split plot design and the treatments were replica

Sheet metal coils are widely used in the steel, automotive, and electronics industries. Many of these coils are processed through metal stamping or laser cutting to form different types of shapes. Sheet metal coil leveling is an essential procedure before any metal forming process. In practice, this leveling procedure is now executed by operators and primarily relies on their experience, resulting in many trials and errors before settling on the correct machine parameters. In smart manufacturing, it is required to digitize the machine’s parameters to achieve such a leveling process. Although s

The total cultivated land area in this context is 8,664,000 square meters, which constitutes about 4% of Egypt's territory. The cultivation relies on old land dams, lines, and furrow surface irrigation systems. A significant portion (76%) of the cultivated land is irrigated with high-density leveled soil instead of unlevelled soil. Leveled soil has very low clay and organic matter content. Land leveling is a preparation or modification process that provides a suitable surface for seeding production. It involves reducing high areas and raising low or deep spots to create a more even surface. La

Due to this difficulty, limited work has been reported on the parameters that influence filament size and methods to characterize it.

Abstract:

The article presents long-term data on the efficient use of water in the Kashkadarya region, as well as their analytical indicators. Agricultural crops, including cotton, require a certain level of moisture in the active layer during the development phases. Natural rainfall is insufficient for optimal soil moisture in cotton cultivation. Therefore, there is a need to artificially moisten the active layer of the soil. There are many forms and methods of artificial soil moistening. At a time when water resources are scarce, the application of new water-saving irrigation technologies is of great

The elevation detection accuracy of the laser receiver in the laser levelling control system directly affects land-levelling operations. To effectively improve the effect of levelling operations and meet the requirements for the accuracy of elevation detection in different industries, this study optimization designed a multilevel adjustable laser receiver. First, we examined the laser signal detection technology and processing circuit, designed the photoelectric conversion array for the detection of the rotating laser, and converted it into a photocurrent signal. We also designed the filter, a

Abstract:

Obtaining reliable data based on the results of geomonitoring allows timely measures to stabilize deformations of buildings and structures. Implementation of the scientific justification for the development of methodological recommendations is required to increase the stability of structures and take the necessary measures to protect buildings in case of detection of unacceptable deformations. Among the causes of deformations, it is possible to single out the imperfection of the structures of the building, the influence of natural conditions (changes in temperature, groundwater level, wind act

Abstract. Airborne Lidar Bathymetry (ALB) is a technology for characterizing the depths of shallow-water bodies in relatively transparent waters from an airborne platform using a scanning and pulsed light beam. A bathymetric LiDAR usually uses wo laser pulses: one is a near-infrared (NIR) laser pulse for land topography and the other is a green laser pulse for submarine topography. In recent years, ALB has become more popular in river and coastal surveying in Japan. The accuracy of ALB has been verified by comparison with the results of acoustic sounding or levelling.

Terrestrial laser scanning technology has developed rapidly in recent years and has been used in various applications but mainly in the surveying of different buildings and historical monuments. The use for terrestrial laser scanning data for deformation monitoring has earlier been tested although conventional surveying technologies are still more preferred. Since terrestrial laser scanners are capable of acquiring a large amount of highly detailed geometrical data from a surface it is of interest to study the metrological advantages of the terrestrial laser scanning technology for deformation

The technologies for implementing the tasks of involving fallow lands in agricultural turnover and increasing the fertility of agricultural lands in the long-term period of economic activity are highlighted. Insufficient informativeness of the use of yield maps to assess the fertility of fields has been revealed. It is proposed to use field relief maps to establish the dynamics of violation of the water-air regime of the soil. It is proved that in the process of involving fallow lands into circulation, it is necessary to introduce a technological operation of microtopographic analysis of the d
