Published: December 2019

Traditional database systems have a common flaw: the many concepts that make up their metadata must be predefined. By concept we mean concepts, terms, entities. To create a new concept, you must resort to programming or change metadata. There are a number of tasks for the solution of which it is necessary to manipulate metadata. The data mining model should be based on a dynamic concept model. The concept of a data model and a data set, as an interpretation of predicates, is introduced. Based on many basic concepts, many generated concepts are given. The classification, verification, falsification of concepts and the expanded context of many concepts are also considered. Using this approach will provide the ability to control the creation and expansion of distributed information systems.

Authors: Dorrer Mikhail
Published: December 2019

The article proposes a mathematical model of the optimal process for managing levels of organization maturity in the presence of interference in the source data. This work is a part of the solution to the more general problem of developing a system for managing the maturity level of business processes in an organization. Changes in organizational maturity of a company are described in terms of a managed dynamic system. It is shown that such a model adequately reproduces a number of effects in the behavior of the system of indicators of the organizational maturity of the company. The paper uses the method of analytical design of optimal Kalman-Letov regulators (ADOR), as well as a recursive Kalman filter that estimates the state vector of a dynamic system based on incomplete and noisy data. The constructed model demonstrates plausible behavior in predicting the process of organizational maturity managing. Reproduces the effect of accelerated growth of controlled indicators defined as a priority in the model. Using the Kalman filter allows one to form a control action on the dynamics of organizational maturity indicators in such a way that the target values of maturity levels are achieved even under conditions that are significantly distorted when measuring the initial data. The proposed methodology for optimal management of the organization’s maturity level is demonstrated by the example of evaluating and forecasting the maturity level of one of the departments of a technical university.

Authors: Goncharenko E A , Paznikov A A , Tabakov A V
Published: December 2019

In this work we analyse the efficiency of atomic operations compare-and-swap (CAS), fetch-and-add (FAA), swap (SWP), load and store on modern multicore processors. These operations implemented in hardware as processor instructions are highly demanded in multithreaded programming (design of thread locks and non-blocking data structures). In this article we study the influence of cache coherence protocol, size and locality of the data on the latency of the operations. We developed a benchmark for analyzing the dependencies of throughput and latency on these parameters. We present the results of the evaluation of the efficiency of atomic operations on modern x86-64 processors and give recommendations for the optimizations. Particularly we found atomic operations, which have minimum (load), maximum (“successful CAS”, store) and comparable (“unsuccessful CAS”, FAA, SWP) latency. We showed that the choice of a processor core to perform the operation and the state of cache-line impact on the latency at average 1.5 and 1.3 times respectively. The suboptimal choice of the parameters may increase the throughput of atomic operations from 1.1 to 7.2 times. Our evidences may be used in the design of new and optimization of existing concurrent data structures and synchronization primitives.

Authors: Lysych M N
Published: December 2019

A classification is given of methods for studying the process of interaction of soil environments with the tillage tools of soil-cultivating machines. The methods are divided into two groups: mathematical modeling and experimental research. Mathematical methods for studying soil interactions using numerical modeling methods that allow one to overcome the shortcomings of analytical and empirical approaches are considered in more detail. A classification, existing software, and an analysis of the possibilities of continuous and discrete numerical methods are given. Studies were performed using continual methods are analyzed: finite element method (FEM) and computational fluid dynamics (CFD). Also studies using discrete methods are considered: the discrete element method (DEM) and the smooth particle hydrodynamics (SPH). An analysis of existing studies has shown that the finite element method can be used for cohesive soils, making it possible to obtain both strength characteristics and data on the process of destruction and displacement of the soil massif. The computational hydrodynamics method can be effectively applied only to the study of the power characteristics of overmoistened soils. Attempts to extend this approach to a wider range of soils lead to significant errors. Discrete methods are most versatile and reliable. So the method of discrete elements allows to reliably assess both the power and quality characteristics of the tillage process. For example, the shape of the transverse profile, the degree of loosening (compaction) of the soil, the nature of mixing of the soil layers.

A method to select the finite element models for the structural analysis of machine tools
Authors: Polyakov A N , Kamenev S V
Published: December 2019

This paper presents a method to select the finite element models for the structural systems of machine tools. The method based on the analysis of modelling results obtained for three different machine tools using the different variants of models. Performed numerical experiments have been shown that the most accurate model is one that involves modelling of feed drives and joints. Increased computational costs, however, may reduce applicability of the model. It was found that the elimination of the feed drives from the numerical model of a machine tool increases the error of modelling (up to 25 %) when static analysis performed. The results of modal and harmonic analysis are more stable to changes introduced to the numerical model of a machine tool, as the error of calculated parameters does not exceed 10 %. Moreover, it was found that the numerical models, which include preloaded joints with stiffness more than 16000 N/μm, are different a little from the models with ideal contact. Thus, it was shown that the use of the machine tool’s numerical model without non-ideal contact and feed drives is more preferable if the acceptable error of modelling does not exceed of 25 %.

The grinding tool does not have a solid cutting edge, in most cases the front angles for abrasive grains are negative, the grains have rounded vertices and an irregular geometric shape. Grinding should be considered as a process of cutting-scratching the surface layer of wood with a large number of abrasive grains of the grinding tool. The main purpose of the grinding process is to prepare the surface for finishing by eliminating irregularities and defects of the previous processing. The effectiveness of grinding to a greater extent depends on the processing conditions, characteristics and properties of the grinding tool. Theoretical studies and analysis of the derived equations for determining the critical values of the rake angle, cut thickness and cutting speed show that all of the above parameters have a significant effect on the amount of lifting of the processed material by abrasive grain and the intensity of the appearance of contact fractures. An increase in the critical thickness of the slice leads to an increase in the deformation of the surface layers of the processed material, and, consequently, to an increase in the depth and number of contact fractures. The increase in the absolute value of the rake angle leads to the need to increase the critical cutting speed to ensure the conditions of chip formation. In general, an increase in cutting speed always has a positive effect on chip formation conditions and on the quality of the machined surface. An increase in the modulus of the rake angle leads to a deterioration in the conditions of chip formation and surface quality. An increase in the radius of curvature of the cutting edge of the grain leads to an increase in the critical thickness of the slice, which entails an increase in contact deformations and fractures.

The article is devoted to the development of applications for Industrial Internet of Things and their integration with Enterprise Resource Planning and Customer Relationship Management systems. This brings to a higher level interaction both of enterprises with each other and with consumers. These processes are most clearly revealed in commercial structure network. The prerequisite for IIoT implementation was the need to determine by the code of the goods not only the destination, but also the storage conditions and the period of realization. An important feature is the necessity to take into account a very short period between the production date and the Expire Date, during which Supply Chain Management is performed, generating storage, distribution, logistics and marketing problems.

This article discusses the possible types of group management strategies. The rationale for choosing a specific group management strategy is given. This article also provides an algorithm for group movement. Then the phases and results of its simulation will be described. Many models can be built for the same system. These models will differ in the degree of detail and account for certain features and modes of operation of the real object, reflect a certain facet of the essence of the system, focus on the study of a certain property or group of properties of the system. Therefore, it is important to state clearly the purpose of modeling at the initial stage of model construction. It is also taken into account that the model is built to solve a specific research problem. The experience of creating universal models has not justified itself due to the bulkiness of the created models and their unsuitability for practical use. To solve each specific problem, you need to have a model that reflects the most important aspects and connections from the point of view of the study. The importance of a specific task of modeling goals is also dictated by the fact that all subsequent stages of modeling are carried out with a focus on a specific goal of the study.

The paper presents an algorithm for non-parametric modeling of the process of cutting dense snow formations with snow plow blade. The following parameters are used as parameters involved in the model: cutting force components, width, cutting angles and installation of snow plow blade, depth of cut and physicomechanical properties of dense snow formations (density from 400 to 500 kg/m3). The initial data for the construction of the model were the results of experiments conducted on a laboratory model of snow plow blade for snow removal equipment. Optimization of the non-parametric regression model was carried out using evolutionary strategies, and the result was improved by local descent methods. The model is necessary to predict the course of the cutting process in a wide range of changes in the parameters in the process of studying and using it on full-scale real snow removal equipment.

The intensification of the transportation processes of mined minerals is one of the key factors in solving the problems of increasing the productivity and competitiveness of the extractive industries. The processes of transportation of mining minerals are associated with their spatial movement by means of belt conveyors. Existing tools for assessing the weight of mining minerals transported by conveyors are based on the use of strain gauge methods and means of control, which allow weighing of mining rocks with acceptable accuracy at a conveyor belt speed of up to 5 m/sec. For conveyors with a high length (more than 10 km), such speed and weighing speed is unacceptable. Therefore, the development of methods and means of controlling the weight of rock transported by a conveyor at high speed is an urgent task. This paper is devoted to the substantiation of the dynamic method of controlling the weight of cargo transported by a belt conveyor based on an assessment of the dynamics of acceleration and deceleration of the rotor of a driving electric motor in steady–state operating conditions.
