Analytics and use of the quantitative analysis of data

Decisions in commercial and non-profit organizations accept proceeding from a number of factors: experience, intuition, results of experiments, analytical researches and the saved-up data. In the commercial organizations the traditional analytics is most often applied to support of internal decisions of the company: "How many has to cost this product?" or "How to stimulate buyers to make at us purchases?" The analytics in the environment of Big Data is often used for development of new types of products or padding consumer properties.Решения в коммерческих и некоммерческих организациях принимают исходя из целого ряда факторов: опыта, интуиции, результатов экспериментов, аналитических исследований и накопленных данных. В коммерческих организациях традиционная аналитика чаще всего применяется для поддержки внутренних решений компании: «Сколько должен стоить этот продукт?» или «Как стимулировать покупателей совершать у нас покупки?» Аналитика в среде больших данных часто используется для разработки новых видов продуктов или дополнительных потребительских свойств

NEUROMUSCULAR AND JOINT DYSFUNCTION OF THE TEMPOROMANDIBULAR JOINT

Aim. To analyse the modern concepts of neuromuscular and joint dysfunction. The article presents the current notion of parafunctional violations of masticatory muscles associated with the loss of teeth, anomalies and deformations in the dento-facial system. We touched the issues of functional overload of periodontium on the background of muscle hypertrophy and related infringement of proprioceptive impulses, which are based on the change of coordination, rhythmic of chewing movements and kinetics of the temporomandibular joint

Development of FEM - Programs for modeling the processes of synthesis by powder metallurgy

The finite element method (FEM) analyzes the features of the spatial distribution of Joule heat in two-phase matrix systems with round inclusions. It was found that in the processes of sintering peaks of heat generation power are formed at certain points of the medium. It is proposed to use the observed phenomenon for the formation of anisotropic and gradient materials. © 2020 American Institute of Physics Inc.. All rights reserved

OCCLUSAL INTERFERENCES AND NEUROMUSCULAR DYSFUNCTION

Aim. The article reflects modern representations of the influence of the traumatic occlusal factor in the pathogenesis of the dynamics of dysfunction of the masticatory musculature, TMJ and inflammatory processes in the periodontium. The main attention is paid to the influence of occlusal factors in the dynamics of the pathological process on the function of the masticatory muscles and the TMJ, and the role of traumatic occlusion on the state of the morphological formations of the periodontium. The enzymatic systems of neutrophil granulocytes and oxidoreductase are important in the disturbance of oxidation-reduction processes, which, in turn, contributes to the growth of intracellular hypoxia with the intensification of destructive processes in the alveolar part of the jaws. To develop a harmonious occlusion, further complex studies of the dentofacial system are needed. Conclusion. The dentofacial system functions on the basis of the complex interaction of the masticatory apparatus which is coordinated by the system of a trigeminal nerve with all its structural components. The complexity of diagnosis and therapy of neuromuscular and articulatory-occlusive syndromes is associated with various concepts about the etiology and pathogenesis of these disorders against the background of a similar clinical picture of their various forms and inadequate methods of treatment

Effect of mexidol on the lipid peroxidation and antioxidant activity of saliva in patients with periodontitis at the background of hypothyroidism

A comparative analysis was carried out concerning the state of the system «lipid peroxidation - antioxidant protection» (POL-AOP) in mixed saliva of patients with chronic periodontitis of mild (n = 22), moderate (n = 20) and severe (n = 18) form at the background of hypothyroidism. As a result of the research it was found that at the background of hypothyroidism there develops an imbalance in the work of all parts of the local system of nonspecific defense of the body, especially at severe periodontitis. And reduction of key enzymes of the antiradical protection (superoxide dismutase and catalase) in mixed saliva is the leading biochemical change that is accompanied by increased inflammation in the periodontium. It is shown that the adaptation increase and AOP therapeutic effect in the shortest term after the use of mexidol is manifested by reducing lipid peroxidation processes, especially in patients with mild periodontitis. Effectiveness of the treatment of moderate and severe periodontitis using mexidol was significantly lower, in comparative aspect

Method of immersion of a problem of comparison financial conditions of the enterprises in an expert cover in a class algorithms of artificial intelligence

The financial condition of the enterprise can be estimated by a set of characteristics (solvency and liquidity, structure of the capital, profitability, etc.). The part of financial coefficients is low-informative, and other part contains the interconnected sizes. Therefore for elimination of ambiguity we will pass to the generalized indicators – rating numbers, and as the main means of research it is offered to use the theory of expert systems. As characteristic of the modern theory of expert systems it is necessary to consider application of intellectual ways of data processing of data mining, or simply data mining. The method of immersion of a problem of comparison of a financial condition of economic objects in an expert cover in a class of systems of artificial intelligence is offered (algorithms of a method of the analysis of hierarchies, contiguity leaning of a neural network, algorithm of training with function of activation softmax). The generalized indicator of structure of the capital in the form of rating number is entered and the sign (factorial) space for seven concrete enterprises is created. Quantitative signs (financial coefficients of structure of the capital) are allocated and their normalization by rules of the theory of expert systems is carried out. To the received set of the generalized indicators the method of the analysis of hierarchies is applied: on the basis of a linguistic scale of T. Saaty the ranks of signs reflecting the relative importance of various financial coefficients are defined and the matrix of pair comparisons is constructed. The vector of priority signs on the basis of the solution of the equation for own numbers and own vectors of the mentioned matrix is calculated. As a result the visualization of the received results which has allowed to eliminate difficulties of interpretation of small and negative values of the generalized indicator is carried out. The neural network with contiguity leaning and function of activation softmax is applied to further smoothing of dispersion of indicators. Application of this method allows to facilitate considerably problems of interpretation of results of comparison of a financial condition of various enterprises

AUTOMATION OF THE DATA COLLECTION PROCESS AS A PART OF THE SOLUTION OF THE PROBLEM OF INFORMING

The problem of informing appears when a large amount of data needs to be communicated to users. The subsequent processing and analysis of information is also very important.
