Points Of View

Discussed are problems of modern mathematical education: the development of the conceptual apparatus of mathematics, as well as the development of thinking in modal categories when proving mathematical propositions and solving probabilistic problems. The work is based on the results of the explication of the ontological foundations of mathematics obtained earlier. It is shown that the basis of a holistic, deep perception of the mathematical laws of being is categorical intuition with subsequent rationalization of mathematical objects. It is emphasized that such objects are not always possible to describe by means of extensional logic: an important place in the categorical structuring of mathematical knowledge is occupied by ontic modalities of the necessary and possible. The author expresses concern about the tendency of algorithmization of mathematical thinking in the learning process as opposed to historically established methods of creative search for proofs, alternatives, and opportunities. Special attention is paid to the topic of the teacher’s implementation of the ideological and educational function of mathematical science. Taking into account the enormous development of computing and information technologies, it is necessary to remember about the anthropological and humanitarian components of modern science and education. In substantiation of the relevance and discussion of the raised issues, the points of view of specialists from various fields are given: mathematicians, historians, teachers. This article is addressed to a wide range of readers: scientists, teachers, graduate students, freelance researchers.

The present article considers the need to predict migration flows using Predictive Analytics. The Russian Federation is a center of migration activity. The modern world is changing rapidly. An effective migration policy requires effective monitoring of migration flows, assessing the current situation in our and other countries and forecasting migration processes. There are information systems in Russia that contain a wide range of information about foreign citizens and stateless persons that provide the requested information about specific foreign citizens, including grouping it on various grounds. However, it is not possible to analyze and predict it automatically using thousands of parameters. Special attention in Russia is paid to digitalization. Using information technologies (artificial intelligence, machine learning and big data analysis) to forecast migration flows in conditions of variability of future events will allow to take into account a number of events and most accurately predict the quantitative and so-called "qualitative" structure of arrivals. The received information will help to develop state policy and to take appropriate measures in the field of migration regulation. The authors come to the conclusion that it is necessary to amend existing legal acts in order to implement information technologies of Predictive Analytics into the practice of migration authorities.

Проблема борьбы с преступностью в современной России является одним из приоритетных направлений государственной политики страны, условием обеспечения ее национальной безопасности. Пенитенциарная преступность выступает составной частью общей преступности и по многим показателям зависит от нее. Общеизвестно, что в местах лишения свободы совершаются преступления. Данные факты свидетельствуют о серьезных недостатках в деятельности уголовно-исполнительной системы, особенно это показательно, если преступления совершаются в колониях-поселениях, контингент которых представлен осужденными за преступления по неосторожности или положительно характеризующимися осужденными, переведенными из исправительных учреждений других видов. В профилактике преступлений важное место занимает организация применения основных средств исправления осужденных, одним из которых является воспитательная работа. В ходе анализа нормативной базы, регламентирующей проведение воспитательной работы, мы пришли к выводу, что многие особенности деятельности колоний-поселений не нашли отражения на законодательном уровне. Считаем, что правовая природа колоний-поселений наделяет администрацию учреждения широким спектром возможностей при организации воспитательного воздействия. С учетом наблюдений практических работников, полученных в процессе интервьюирования, мы предложили ряд изменений в нормативные акты, которые регулируют воспитательную работу. Их внесение в законодательство, по нашему мнению, будет способствовать совершенствованию организации воспитательной работы с осужденными, что в свою очередь позволит снизить уровень преступности в колониях-поселениях. The problem of combating crime in modern Russia is one of the priority areas of the country's state policy, a condition for ensuring its national security. Penitentiary crime is an integral part of overall crime and depends on it for many indicators. It is common knowledge that in places of deprivation of liberty crimes are committed. These facts reveal serious shortcomings in the functioning of the penal system, especially when crimes are committed in penal settlements, where the population is represented by those convicted of crimes by negligence or those transferred there from correctional institutions with different regime due to their conscious conduct. In crime prevention the organization of the use of basic means of prisoners’ correction, one of which is educational work, takes an important place. In the process of the analysis of the regulatory framework governing educational work, we came to the conclusion that many features of the activities of penal settlements were not reflected at the legislative level. We believe that the legal nature of penal settlement gives the administration of the institution a wide range of opportunities in organizing educational impact. Taking into account the observations of practitioners obtained during the interview process, we proposed a number of changes to the normative base that regulate educational work. Their introduction into legislation, in our opinion, will contribute the improvement of the organization of educational work with prisonerss, which in turn will reduce the level of crime in penal settlements.

The One

The paper is divided into two parts. In the first one, I set forth a hypothesis to explain the failure of Husserl’s project presented in the Philosophie der Arithmetik based on the principle that the entire mathematical science is grounded in the concept of cardinal number. It is argued that Husserl’s analysis of the nature of the symbols used in the decadal system forces the rejection of this principle. In the second part, I take into account Husserl’s explanation of why, albeit independent of natural numbers, the system is nonetheless correct. It is shown that its justification involves, on the one hand, a new conception of symbols and symbolic thinking, and on the other, the recognition of the question of “the formal” and formalization as pivotal to understand “the mathematical” overall.

In every aspect of Engineering more advanced, efficient and progressive solutions are required. The modern age of science requires innovative minds. The field of environmental engineering is also advancing with modern science and technology innovations. Measuring of methane concentration and flow rate is nothing new, yet a complicated process. The need for more accurate measurement is a necessity in proper operation of bio digesters for methane generation. The traditional process of the measuring methane content in biogas is time consuming yet complicated. The need for development and application of methane measurement techniques is not only limited to biogas but has other monitoring value as well in other health and safety applications in built environments. Winsen Electronics and Hanwei Electronics are two of the leading sensor-manufactures of China who are providing a wide range of gas detecting sensors that are locally available in Bangladesh and yet has not been applied to methane content measurement in biogas operations. In This paper we are reporting on the application of a purpose-built propane, butane detector for methane gas detection within the range of accuracy for it to be applied in methane detection in a biogas stream. This paper, reports on application and calibration of the methane detecting sensor MQ-4 with promising result. Based on the study we postulate that the sensor can be used to detect methane for an on-line monitoring of many environmental, industrial purposes such as bio digesters, integrated waste management facility. The cost of fabrication of the sensor system is only $18 making it a viable sensor with respect to cost for application in Bangladesh.

Disorders of hemostasis occupy an important place in the structure of vascular diseases and are one of the most frequent pathological conditions encountered in practical medicine. The hemostasis system is naturally the most vulnerable system of the body. Violations of its balance are found in a wide variety of physiological and pathological conditions of the body. It is not uncommon for the first debut of decompensation to lead to an ophthalmologist. In the practice of an ophthalmologist, there are diseases when it is necessary to pay close attention to thrombophilic conditions. Changes in the hemostatic system, affect a wide range of vascular diseases of the eyeball. Recognition of the type of thrombophilia and its timely laboratory diagnosis in patients with vascular diseases of the retina and optic nerve are important in achieving the best treatment results. Multidisciplinary approach to the treatment of vascular diseases of the eyeball and modern diagnostics, including the study of hemostasis, is necessary and relevant to achieve the best clinical and functional treatment result. Timely and correct orientation of patients in vascular pathology is extremely important due to the fact that concomitant systemic pathology can aggravate the course of the disease, therefore, the choice of treatment tactics for this category of patients should be carried out in conjunction with a therapist, cardiologist, hematologist and endocrinologist. Key words: hemostasis, thrombosis CVS, diabet, primary open-angle glaucoma thrombodynamica, cardiovascular pathology.

The article discusses approaches to the interpretation of the concept of a service, its specific differences from a physical product and the main features as an object of purchase and sale in the relevant market. Based on the analysis and systematization of existing scientific views, the main features of the service market and the features of the interaction of supply and demand in the service sector are revealed. The practice of functioning of the service market demonstrates the high dynamics of market processes, a pronounced segmentation of demand for services, a high degree of differentiation of services, a high rate of capital turnover and the important role of non-price barriers to entry into the market. The essence and value of the customer's customer loyalty for successful commercial activities and increasing the competitiveness of the manufacturer-supplier of the service has been investigated. Loyalty becomes an indicator of business performance and its ability to innovate. A customer-oriented business philosophy, where a wide range of factors of influence on the formation of customer loyalty is taken into account and used, will allow the company to count on long-term relationships with the consumer and will attract new customers through his positive experience. The possibilities and features of the application of competitive strategies by firms in the field of service activities were analyzed. The main trends in the development of the services market in the current stage, namely the processes of its digitalization, have been investigated. The buyer today is interested not only in price and quality, but also in good service. If a company meets customer service demand through the introduction of chat bots, self- service terminals, mobile applications, etc., then this contributes to the formation of a positive customer experience, which ultimately increases sales. The features and advantages of using information technologies both in business activities and in the implementation of consumer choice have been determined.

Fault State

In this work, we propose a new and simple method to insure an online and automatic detection of faults that affect induction motor rotors. Induction motors now occupy an important place in the industrial environment and cover an extremely wide range of applications. They require a system installation that monitors the motor state to suit the operating conditions for a given application. The proposed method is based on the consideration of the spectrum of the single-phase stator current envelope as input of the detection algorithm. The characteristics related to the broken bar fault in the frequency domain extracted from the Hilbert Transform is used to estimate the fault severity for different load levels through classification tools. The frequency analysis of the envelope gives the frequency component and the associated amplitude which define the existence of the fault. The clustering of the indicator is chosen in a two-dimensional space by the fuzzy c mean clustering to find the center of each class. The distance criterion, the K-Nearest Neighbor (KNN) algorithm and the neural networks are used to determine the fault type. This method is validated on a 5.5-kW induction motor test bench.Article History: Received July 16th 2017; Received: October 5th 2017; Accepted: Januari 6th 2018; Available onlineHow to Cite This Article: Ouanas, A., Medoued, A., Haddad, S., Mordjaoui, M., and Sayad, D.

The issues of using mathematical knowledge in the investigation of crimes are considered. It’s indicated that the application of mathematical methods in the investigation is limited by the wide range of ways of establishing evidentiary information, which are not always subjected to the mathematical calculations. We have drawn attention to the fact that the modern use of mathematical methods is basically reduced to the use of algorithms in various aspects of the process of investigating crimes. It’s defined that the purpose of algorithmic investigation activity is its optimization, efficiency, objectivity of the results, reduction of the terms of investigation and creation of real conditions for the development of automated systems for processing and evaluating of the received information, taking decisions in certain typical situations. The importance of criminalistic algorithms in choosing optimal tactical solutions is substantiated in the situations, where there are several variants of solutions and the ambiguity of the expected results when making a decision. Two groups of investigation tasks are presented which are divided among themselves, depending on the clarity of the initial information, which was used in their formation. There is shown a relationship that exists between the analysis of the initial information in the formulation of a tactical task and the choice of an algorithm for its solution by making tactical decisions. It’s pointed out that the uncertainty and incompleteness of the initial data of the tactical task considerably complicates the use of mathematical algorithms. There is analyzed the use of algorithms in the construction: of a private technique for investigating crimes; of a tactical operation; when forming a system of tactical methods. Critical remarks are presented about the available modern algorithms (programs) of the investigator’s actions as non-concrete, multivariate and not reflecting the logical sequence of actions aimed at accomplishing the tasks of investigation and achieving the desired result.

The most important place among the measures of administrative coercion is occupied by measures of administrative restraint, highlighted by all authors dealing with public administration issues and investigating the effectiveness of the methods used to implement executive power. The current legislation provides for a significant arsenal of tools that are a way to respond to the cessation of violations in the field of public administration. Covering various public relations, these measures are very successfully applied in the implementation of licensing legal relations. Licensing and the implementation of subsequent licensing control involves the active use of administrative measures such as revocation or revocation of the license, suspension of its validity, as well as the issuance of an order to eliminate violations of the license legislation. At the same time, there are different points of view on the issue of attributing certain measures to administrative measures of restraint, which caused the need for additional reference to this topic of research. The author draws conclusions and expresses his own opinions on the types of administrative preventive measures related to the licensing and licensing sphere.

The article deals with the status of the speech genres theory (SGT) and its contribution to the development of modern linguistics. In his polemical article Professor V. V. Dementyev argues that SGT is characterized by the wide range of research problems, a close connection with such academic domains as the theory of speech acts, colloquial studies, discourse analysis, linguistic personology and other areas that study a human and their language. This thesis does not raise objections, as the 21st century is considered to be the century of syncretism and interpenetration of sciences, which has become one of the main features of the entire post-non-classical science. This approach provides a holistic reflection on the object of study, in this case, on the language. It is called syncretism, integrity, interdisciplinarity, polydisciplinarity, transdisciplinarity. In general, these terms are synonymous, because they are based on the idea of holism of everything in the world. In this sense, SGT is in line with modern science. The thesis of V. V. Dementyev on the diffusion of genres. Diffusion can be considered as the most important trend not only in science, but also in the entire modern culture, which is shown with the help of examples. However, some statements of V. V. Dementyev’s article seem debatable: the problem of the pervasiveness of SGT in linguistics in its entirety, which can give rise to a dangerous tendency – the absorption of linguistics by SGT. Their interests do often overlap, but each of the named areas solves the problem of personal communication in a social environment in its own way, and each of them has its own subject and its own history. Today SGT cannot take into account many of the processes occurring in discourse, but this is a relatively new science with a great future.
