Abstract: The possibility of using remote sensing data to assess the density of urban development is demonstrated. For the example of the Zapadnoe Kuntsevo residential complex, it is found that the actual rate of development differs significantly from the value proposed by Sizov. The development density coefficient (0.3) is within public health standards. The greatest rate of development was observed in 2013 and 2014. Evidently, the formula for the rate of urban development must be corrected to take account of periods of intense growth. Analysis of the NDVI index indicates that the rate at which farmland close to residential complexes is taken over is increasing.

Abstract: The article presents an algorithm for calculating the parameters of a digital model of a 3D surface in accordance with GOST-25178-2–2014.3267 “Geometrical Product Specifications (GPS)” on the example of a surface treated with an abrasive tool. Microgeometry of working surfaces of machine parts is an important factor in determining their durability, reliability, and efficiency in operation. The developed models enable control over the parameters of the treatment process at the stage of design of the technological process with the aim to ensure required geometric parameters of the machined surface. he problem is a relevant issue because surface microrelief characteristics determine the area of real contact, the coefficient of friction, the ability to hold lubricant, and the ability of the working surface to withstand wear under load. Optimization of microgeometry can result in reduced wear, improved efficiency, and increased reliability of mechanisms.

Abstract: The helical surfaces on the cutting section of end mills determine their operational efficiency and the product quality. Preparations for machining those surfaces include determining the position and orientation of the standard grinding wheel. That is a challenging problem, since the standard wheel does not share a single cross section with the helical profile. Consequently, the usual methods do not permit the determination of a broad set of geometric parameters for a specified setup. Therefore, in the present work, a mathematical model is proposed for the multicoordinate grinding of helical surfaces on high-strength tool materials. The model takes account of wheel profiles with different curvature, dimensions, and shape; the characteristics of multicoordinate wheel motion in the tool coordinate system; and the shape of the machined surface in the helical channel. The model is universal and greatly facilitates the development of shaping configurations for helical surfaces of different profile.

Abstract: Conical end mills are widely used as cutting tools in the production of components for the aerospace industry and for machine building. The helical channel of conical mills is more complex than a regular cylindrical channel. Its core diameter and profile angle are variable. The operational efficiency of the mill depends directly on those angles and on the rake angle at the edge. Multidimensional tool motion is required to produce conical helical channels; recalculation is necessary at each stage of the motion. Determination of that motion calls for comprehensive solution of the profiling problem; some new developments in such research have appeared recently. In the present work, the change in the shaping configuration in terms of the cut layer width is analyzed. Recommendations are made regarding the determination of the shaping configuration; its influence on the shape of the machined sections at the front and back of the mill tooth in the helical channel is considered. The most important approaches to machining conical end mills are discussed. On the basis of the analysis, a new algorithm is derived for positioning the grinding wheel with respect to the mill axis on the basis of its contact parameters at a helical conical surface.

Abstract: SolidWorks Simulation software is used to analyze the stress state of one-sided butt welds that contain a convex element and a gap (incomplete fusion) at the root of the seam. Convexity of the weld seam intensifies the stress concentration due to the gap and increases the maximum stress in the weld. To minimize the stress in the weld, its convexity must be completely eliminated, and a groove of depth equal to the gap height must be made along the whole seam.

Abstract: A new approach to the design of motor vehicle suspensions by simultaneous use of several damping devices of different types, making up a combined damping system (CDS), is presented. A rational combination of the components of the CDS and optimization of their parameters ensure an increase in the smooth running of the motor vehicle. Calculation and analysis of the damping properties of air suspension (AS) with different CDSs made it possible to determine the most effective systems.

Abstract: Relations are established between various indices for the condition of the plant cover and humus content of the soil. Spectral reflective characteristics of vegetation are determined by analysis of images in different channels from the Sentinel-2 satellite using linear regression and random forest algorithms. It is found that the vegetation indices NDI45 and PSSRa are more sensitive to the humus content in the soil than the indices RVI and NDVI. The determination coefficient (R2 = 0.59) and mean square error (MSE = 0.00 014) indicate that the predictive power of the proposed model is good.
