The brief characteristic and a technique of realization of the analysis and improvement of administrative and industrial business business-processes are given in the article. The offered approach and a technique of realization of research of business-processes allow to develop information systems at the enterprises an…
In the previous papers for the integral Fredgholm equation of the first kind with a degenerate kernel the generalized (non regularizing) version of the projection method was developed, based on the arbitrary choice of the basis combined with some a priori estimations for the error of the solution. These estimations de…
Wear resistant criterion suggested for choice of the fused surfacing hard alloys for hard usage. The criterion investigation is advisable for composition of hard alloys selection. The increase of wear resistance achieved by means of simultaneous enlargement of hard inclusions content and bending ultimate strength with…
The changes of organization have a different directions depending to company activities.This text is about restructuring as a basic stage of business processes development. To create the flexible, ready-and-able for changes organization we should understand the transformations necessity, then develop the restructuring…
This article shows a main point, reasons of social conflicts and methods of controlling them for decreasing of social tension in the society and realization of an election campaign.
The analysis of Nd-Fe-B based alloy crushing products grain size distribution was used to investigate the peculiarities of alloy crushing process in the impact mill at various electromagnetic field parameters. The correlation of constant and variable magnetic field induction and variable magnetic field induction gradi…
The outcomes of rational design of semiproducts in process of die forging for the forging of the hemispherical shape are submitted. The approach is realized by a boundary-element solution of a sequence of inverse tasks of metal flow when filling the die cavity on algorithm reverse loading. The obtained solution allows…
As a result of carried out research of bioelectric activity of heart at intensively training sportsmen and practically healthy people are revealed by an electrocardiogram-change, reflecting a condition of an overstrain of a myocardium of sportsmen in conditions of excessive physical activities.
The work analyses the dependence of hard-alloyed materials contacts surfaces adhesive bond on yield limit of various steels.Some quantative values of adhesive forces, adhesive coefficients and adhesive bond strength used for phenomena evaluation as well as for approximate calculations are reached.
The production technology of the quality control, it’s strategy and planning in the process planning with the ability of aid with the computer is the important component of the improvement of the quality stability of the production according to the set of standardsPN-EN29000. The review and the essence of works, which…
In the article the method of accuracy increasing of manufacturing details on the technological equipment by means of additional signal formation for keeping up drives depending on movement parameters of working body is considered. The structure of the adaptive neural network focused on problems of keeping up drives co…
Three-dimensional acerbity and its determination. The notion three-dimensional acerbity element of the hydraulic system is Offered. Happen to the got analytical way of the formula for determination brought three-dimensional acerbity different element hydraulic system, as well as formula for determination brought three…
In this article, the areas of existence of the major financial parameters and the types of dependences appropriate to them are revealed. Ordering of financial parameters as dependences has allowed to reveal leading parameters wich can be used for definition of an orientation of development of the enterprise from all s…
The paper considers technological structure of the economy as a factor of the country’s absorptive capacity. The work is based upon the statistical analysis of the main developed countries. The author reveals a regularity, which connects the structure of the interindustrial linkages with its capacity to adopt foreign…
The article proposes a new method of modeling the evolutional system, which interacts with the environment. The cutting process or tribo-space, which are formed in the contact area of two conjugate mechanical subsystems, are considered as an environment. The features of the environment depend not on the coordinates of…
Organization of production is one of the directions of STP (Scientific Technological Progress). It place an important role in increase in enterprise efficiency. The application of new technologies is not always effective at the low level of organization. The increase in enterprise efficiency depends on organization of…
Interests are being focused on types of nonvolatile memories such as ferroelectric random access memory (FRAM), phase change random access memory, or magnetoresistance random access memory due to their distinct memory properties such as excellent write performance which conventional nonvolatile memories do not possess…
Maintaining functions of endothelial cells in vitro is a prerequisite for effective endothelialization of biomaterials as an approach to prevent intimal hyperplasia of small-diameter vascular grafts. The aim of this study was to design suitable nanofiber meshes (NFMs) that further maintain the phenotype and functions…
Scaling of the structural order parameter, polarization, and electrical properties was investigated in model ultrathin epitaxial SrRuO3∕PbZr0.2Ti0.8O3∕SrRuO3∕SrTiO3 heterostructures. High-resolution transmission electron microscopy images revealed the interfaces to be sharp and fully coherent. Synchrotron x-ray studie…
Abstract There exist several methods for the production of highly porous materials; among these, replication processing is well‐adapted for open‐pore microcellular structures. The process begins by making a porous preform, open pores of which are filled with the foam material. Thereafter the preform is removed, genera…
