The article discusses the specific character of the representation of the notion “Security Architecture” presenting the concept “Construction” in Russian, German and English linguistic fields. The peculiarities of the cultural and historical development, fundamental divergences of the political systems,
levels of economic and social progress, different world -view and world interpretation of Russia, Germany, Great Britain and the USA resulted in causes of the polar appreciation of the notion “Security Architecture” from the point of view of national and international interests. The increasing tendencies of the global changes in the world politics and political line of these countries are reflected in lexical language figures and in social journalism realized in the political discourse. The undertaken trends of the lexical-semantic and comparative analysis of present lexical units and certain texts of Russian, German and Anglo-American printed mass media and research papers have revealed the different comprehension of the notion “Security Architecture” in the national linguistic cultures. It made possible to draw a conclusion on polar connotation of the notion in Russian, German and English conditioned by the specified tendencies in political, ideological and economic fields. To the opinion of the author the notion “Security Architecture” presented by the concept “Construction” because of its actualization may claim to be universal and therefore be related to the constants of culture. In this regard, the analysis of the notion “Security Architecture” as a part of the present concept is of a substantial interest. Due to results of the present research, the author resumes the peculiarities of explication of cognitive signs and the reasons influencing the transformation of the notion in Russian, German and English linguistic cultures
The article is devoted to the development of basic children’s skills with disordered autism spectrum. There is a range of tasks that need to be addressed in the system of psychological and educational assistance to children in this category, which allows identifying problems and areas of work with these children. The theory of deviant development and autism spectrum disorders, the concept of the game as the leading activity of children of preschool age and mental structures formed in this type of activity; the role of the concept of physical education in the development of mental processes of preschool age children is the methodological basis of the research. The article presents a model of improving sensory perception of the world around skills, skills of gross and fine motor skills, communication and social development with children with disordered autism spectrum. The conceptual framework of the proposed model is system development of sensory, motor, social and communicative skills of the child through interactive physical games. The purposes, goals, pedagogical conditions of realization of the model are determined. The model consists of three parts: a target, process, control and evaluation. The first - the target includes the purpose, tasks, and pedagogical conditions of realization of the model. The second set of model is technology. It consists of 5 blocks: sensory development, gross motor skills, fine motor skills, communication, and social skills. The implementation of the content of the second unit takes place by means of interactive physical games, game exercise. There are the aims, the content of each unit. The third block is the control and evaluation. The content of the work of the third block includes organizational and methodological activities to assess the level of development of basic skills in children with ASD. According to the results of diagnosis, routes of individual development of each child, as required mid-term evaluation is carried out and a change of formation of skills development route have been made
The need to ensure the environmental safety of Russia is
becoming increasingly important nowadays. The article
defines environmental security. The article defines the
role and the place of environmental security in the
national security system of the country. Understanding
the essence of environmental problems among
populations is a necessary step for the implementation of
environmental safety. We provide statistical data of
regions of Russia with a very difficult economic
situation, as well as the proportion of organizations
interested in environmental safety. We have proven
ecological degradation after the analysis of the
environment and proposed mechanisms of environmental
security. The study also reflects the need for changes in
the environmental consciousness of the population. The
article provides a rationale for the importance of
environmental education to ensure the ecological
security of the country during crisis. We reveal the
understanding of the fact that sustainable development of
Russia and national security will be provided only under
condition of preservation of natural systems and
appropriate support of the state. The article focuses on
the need to develop ways of improvement of legal
regulation in the field of environmental security of the
country. There is a need for public policy that should be
aimed at ensuring the environmental security of the
country. Therefore, environmental security is an
important component of national security, which might
become a national idea uniting the peoples of the
Russian Federation
Classic quantitative measure of the reliability of the models: F-measure by van Rijsbergen is based on counting the total number of correctly and incorrectly classified and not classified objects in the training sample. In multiclass classification systems, the facility can simultaneously apply to multiple classes. Accordingly, when the synthesis of the model description is used for formation of generalized images of many of the classes it belongs to. When using the model for classification, it is determined by the degree of similarity or divergence of the object with all classes, and a true-positive decision may be the membership of the object to several classes. The result of this classification may be that the object is not just rightly or wrongly relates or does not relate to different classes, both in the classical F-measure, but rightly or wrongly relates or does not relate to them in varying degrees. However, the classic F-measure does not count the fact that the object may in fact simultaneously belongs to multiple classes (multicrossover) and the fact that the classification result can be obtained with a different degree of similarity-differences of object classes (blurring). In the numerical example, the author states that with true-positive and true-negative decisions, the module similarities-differences of the object classes are much higher than for false-positive and false-negative decisions. It would therefore be rational to the extent that the reliability of the model to take into account not just the fact of true or false positive or negative decisions, but also to take into account the degree of confidence of the classifier in these decisions. In classifying big data we have revealed a large number of false-positive decisions with a low level of similarity, which, however, in total, contribute to reducing the reliability of the model. To overcome this problem, we propose a L2-measure, in which instead of the sum of levels of similarity we use the average similarity by different classifications. Thus, this work offers measures of the reliability of the models, called L1-measure and the L2 measure, mitigating and overcoming the shortcomings of the F-measures; these measures are described mathematically and their application is demonstrated on a simple numerical example. In the intellectual system called "Eidos", which is a software toolkit for the automated system-cognitive analysis (ASC-analysis), we have implemented all these measures of the reliability of the models: F, L1 and L2
In 1893, the French mathematician J. Adamar
raised the question: given a matrix of fixed order
with coefficients not exceeding modulo this value,
then what is the maximum modulo value can take
the determinant of this matrix? Adamar fully
decided this question in the case when the
coefficients of the matrix are complex numbers and
put forward the corresponding hypothesis in the
case when the matrix coefficients are real numbers
modulo equal to one. Such matrices satisfying the
Hadamard conjecture were called Hadamard
matrices, their order is four and it is unknown
whether this condition is sufficient for their
existence. The article examines a natural
generalization of the Hadamard matrices over the
field of real numbers, they are there for any order.
This paper proposes an algorithm for the
construction of generalized Hadamard matrices,
and it is illustrated by numerical examples. Also
introduces the concept of constants for the natural
numbers are computed values of this constant for
some natural numbers and shown some
applications of Hadamard constants for estimates
on the top and bottom of the module of the
determinant of this order with arbitrary real
coefficients, and these estimates are in some cases
better than the known estimates of Hadamard. The
results of the article are associated with the results
of the con on the value of determinants of matrices
with real coefficients, not exceeding modulo units
In the article we investigate the multicriteria task
arising at the organization of distributed calculations
in a corporate network. As a mathematical tool to
solve the problem we use prefractal graphs, which
naturally reflect the structure of relationships in
global and corporate networks. The corporate network
with the distributed computing system at the solution
of a particular task has to be reliable, quickly and
qualitatively to make decisions. And every computer
in the network should be a part in the solution of the
problem, since it is fixed for a certain function. The
problem is reduced to cover the prefractal graphs with
disjoint simple paths along the edges and vertices.
On the set of all admissible coverings we constructed
a vector-target function with specific criteria. All
these criteria have a specific meaningful
interpretation, allowing organizing the calculation of
maximum reliability, with minimum time information
processing and loading balancing between the
network elements. In the article we constructed
polynomial algorithms for finding optimal solutions
according to specific criteria. For the criteria which
are not optimizing the allocated coverings, estimates
of the lower and upper bounds are given. For all the
algorithms we constructed and substantiated
estimation of computational complexity, confirming
the advantage of using algorithms on prefractal
graphs to classical algorithms on graphs
The article continues the cycle of their studies
associated with the formulation and development of
methods of construction of nonnegative solutions of
inverse problems for dynamic systems. In this article
the authors formulated and investigated inverse
problems for dynamic systems: model of Samuelsson–
Hicks. The technique of constructing non-negative
solutions of the studied inverse problems. This method
is based on the following scheme of the solution. First,
we have to identify the formulation of the direct
problem, then the formulation of the inverse. This
work investigates how correct the mathematical
models describing the dynamic economic system are.
Further, in the specified tabular solutions of the direct
problem, we have built a system of algebraic equations
containing the unknown estimated parameters of the
studied model. Then posed inverse problem is reduced
to solution of a problem of quadratic programming, the
solutions of which are defined in MS Excel. The
theoretical material is accompanied by the specific
example
Atmospheric currents on Jupiter and Saturn are
characterized by turbulence and complex vortex
structure, which is caused by a large angular speed of
the gas giants. In this paper we consider two types of
eddy currents - for hexagonal in the northern polar
region of Saturn and the Great Red Spot in the
equatorial region of Jupiter. For the numerical
simulation of turbulent flows of this type the model of
the planetary boundary layer was developed by the
author. In both cases, the main strengthening
mechanism is associated with geostrophic flow of
small amplitude interacting with the planetary
turbulent boundary layer. For hexagonal Saturn with
its characteristic length scales and speed - 120 m / s
and 14,500 km, respectively, there are more than 35
years data of observation. We have found that a small
axial symmetry violation geostrophic flow in the
shear causes the development of a hexagonal pattern
in a turbulent boundary layer. In addition, under the
influence of the Coriolis force and the eddy viscosity
gradient in the turbulent boundary layer there is the
jet formed, pressed against the lower edge of the
layer. Great Red Spot on Jupiter has the characteristic
velocity and length scales - 150 m / s, 14,000 km
from north to south and 24000-40000 km from west
to east, there are already more than 350 years data. It
identified another mechanism of formation of vortex
flow, coupled with the strengthening of small
amplitude zonal flow in a turbulent boundary layer
with the eddy viscosity gradient and the volume
turbulent viscosity on a rotating planet. Both
mechanisms are confirmed by numerical calculations
of non-stationary planetary boundary
layer
Theoretically and experimentally, we investigated the
process of adjusting the pH of natural water of
hydrocarbonate class electrodialyzer with bipolar
membranes with channel length of 40 cm. We
experimentally measured concentration of
components, pH of the solutions in alkaline and acid
channels of electrodeposition depending on the current
density. The article describes a mathematical model
for long channels; to scale the mass transfer
characteristics of the process there was applied and
verified a method of compartmentalization, which
gave the possibility to calculate the dependence of the
component along the channel length at different
velocities of flow of the solution. Numerical
calculations were compared with experimental data on
electrodialyser of 10 cm and 40 cm length
The influence of reduced iron nanoparticles and its oxide Fe2O3 on the growth rate of Chlorella vulgaris IFR # S-111 added to the Tamiya nutrient medium is studied. In the range of concentration of additives 0-0,1 g/l (gram per litre) an oxide inhibited the growth of microalga already when its content in the environment 6,25*10-3 g/l. With the increase of reduced iron concentration in the first twenty-four hours in the whole range the growth of the cell concentration of microalga was observed. With a maximum iron concentration of 0,1 g/l the density of a chlorella exceeded the control for 70%, and in 48 hours for 150%. The microscopy hasn't shown morphological changes of a chlorella cells with addition of the nanoparticles to nutrient medium. Accelerated reproduction of the microalga cells became the result of the intensification of the photosynthetic processes, as indicated by the nature of the parameters of delayed fluorescence (DF) of chlorophyll and shapes of the induction curves. The maximum level of DF in all experimental samples after 24 hours of cultivation was significantly higher than the control, and photosynthetic activity increased with increasing concentration of nanoparticles. In 48 hours the maximum activity was observed at concentration of nano iron 0,0125 mg/l, then decreased. It shows that with an intensive growth of a chlorella the potential of nutrient medium was quicker exhausted that led to decrease in intensity of photosynthetic processes
