The paper presents the results of experiments in a circle drilling. Namely, the results of data processing load on the cutter (blade) moving in a certain radius, with step-checkboarded and sequential circuits of arrangement on the crown of ring bore. The paper presents the stresses of this incisor, with the two constellations, their relationship to each other. As a result, the conclusions brought under any scheme of arrangement of cutting elements are obtained by the least energy-intensive process.

Abstract:

The crux in the locally linear embedding algorithm or LLE is the selection of embedding dimensionality and neighborhood size. A method of parameters selection based on the normalized cut criterion or Ncut for classification tasks is proposed. Differing from current techniques based on the neighborhood topology preservation criterion, the proposed method capitalizes on class separability of embedding result. By taking it into consideration, the intrinsic capability of LLE can be more faithfully reflected, and hence more rational features for classification in real-life applications can be offer

Therefore, when calculating it, you must already know the size of the drive, which is still unknown, since it is only being installed. This question is especially relevant for low-frequency oscillatory systems with an inertial drive, in which the inertial parameters of the drive are propor

Abstract:

Blades are important components of aircraft engines. Free-form surface blade machining generally adopts sub-regional processing and cutting parameters vary greatly. Rational optimization of the cutting parameters can improve blade processing quality and efficiency in aerospace industry. To control the processing deformation of the blades, a method using artificial neural network and genetic algorithm is presented to optimize the cutting parameters. The method can reduce cutting parameter selection time and improve blade processing quality.

Abstract:

In this work, we study a time-fractional ion sound and Langmuir waves system (FISLWS) with Atangana–Baleanu derivative (ABD). We use a fractional ABD operator to transform our system into an ODE. We investigate multiwaves, periodic cross-kink, rational, and interaction solutions by the combination of rational, trigonometric, and various bilinear functions. Furthermore, 3D, 2D, and relevant contour plots are presented for the natural evolution of the gained solutions under the selection of proper parameters.

Abstract:

Background Artifact robustness (i.e., size of deviation of an electroencephalographic parameter value from baseline caused by artifacts) and baseline stability (i.e., consistency of median baseline values) of electroencephalographic parameters profoundly influence electroencephalography-based pharmacodynamic parameter estimation and the usefulness of the processed electroencephalogram as measure of the arousal state of the central nervous system (depth of anesthesia). In this study, the authors compared the artifact robustness and the interindividual and intraindividual baseline stability of s

Single-bucket front loaders are usedwidelyin road construction. In some cases, their use is more rational than traditional digging and earth-moving machines.Front loaders have a high-er bucket capacity per unit weight, high maneuver-ability and lower operating costs compared to sin-gle-bucket excavators. This allowsyou to develop grounds in small bottoms without compromising productivity.Improvement of the loader use effectiveness throughout the year can be achieved by armory it with replaceable working equipment.The existent working equipment range contains buckets for various purposes (main,

Abstract:

Relevance. As the weight and complexity of the payload that needs to be launched into orbit increases, the relevance of rational trajectory selection to ensure maximum efficiency and minimum costs for delivering the payload to a given orbit increases. Rational choice of the trajectory of a heavy-class launch vehicle has a number of important practical applications. Firstly, it allows you to increase the payload capacity of the launch vehicle and reduce the cost of delivering payload to the target orbit. This is especially important in the context of the development of the space industry, when

Abstract:

In the practice of modern construction, light concretes of low thermal conductivity are used as a heat-insulating layer of enclosing structures. In particular, they are used for warming flat roofs of buildings for various purposes. One of the effective methods of thermal insulation is the use of polystyrene concrete of low average density and thermal conductivity directly in construction conditions. Research has established a rational selection of the composition of this type of concrete for the installation of a monolithic heat-insulating layer, resource support for the technological process,

Abstract:

Different structures and different structural members should reasonably be assigned different levels of reliability to obtain optimum structural performance. This differential assignment of reliabilities or safety parameters is called "safety level differentiation." Up to the present, no simple practical rationale is available for the selection of safety levels. This paper presents a methodology for the selection of safety levels. Cluster analysis is suggested as a tool in the calibration of limit states design codes. The technique may be used to develop importance factors for the design loadi

Abstract:

A type of rational interpolation operator (RIO) with parameter ? is studied in this paper. We give the specific construction of RIO based on Chebyshev nodes of the fourth kind, and calculate the approximation order of the RIO to functions when 1 < ? < 2 and ? > 2 respectively. Furthermore, we analyze the relation between the parameter ? and the approximate error, while the latter is between the operator and the function. By selecting the sampling function and adjusting the parameter, the theoretical results are visualized and verified from the images and error data tables.
