The phenomenon of electro convection in membrane systems is of considerable interest, because it is, according to many authors, the main mechanism of overlimiting mass transfer. A great number of theoretical and experimental works, in which, as a rule, dimensional values were used, are devoted to electro convection study. Because of that, in actual fact, there is investigated the influence of individual factors on the transfer process. For example, the influence of voltage jumps, the average speed of a forced stream of the solution, the geometric characteristics of the channel, the initial concentration, etc. However, the influence of these factors appears not separately, at the same time. Thus, there is the problem of introducing dimensionless complexes of dimensional values that have a physical meaning and that allow to evaluate the inner links of the process. As it is known, for solving that problem, there is applied a theory of similarity, based on the transition towards dimensionless parameters in equations and formulas describing the process, and using values, typical of the system under study. This work is devoted to the determining of physical meaning of similarity criteria of salt ions processes, taking into account electro convection in the desalting channel of electro dialysis apparatus. The channel is bounded with perfectly selective, homogeneous anion-exchange and cation-exchange membranes. The introduced similarity criteria are used so as to conduct the theoretical study of the effect of a number of parameters of a desalting process on electro convection
The article suggests a mathematical model of optimization of the volume of material flows: the model for the ideal conditions; the model for the working conditions; generalized model of determining the optimal input parameters. These models optimize such parameters of inventory management in technology-integrated grain production systems, as the number of cycles supply, the volume of the source material and financial flows. The study was carried out on the example of the integrated system of production, processing and sales of wheat (bread) with the full technological cycle
In this article, in accordance with the methodology of
the Automated system-cognitive analysis (ASCanalysis),
we examine the implementation of the 1st
and 2nd stages of ASC-analysis: cognitive structuring
and formalization of the subject area. At the stage of
cognitive structurization of subject area, researchers
decide what to consider as the object of modeling, the
factors affecting it and the results of their actions. In
accordance with the results of the cognitive structurization,
we prepare the initial database for the study
(training sample or case-based reasoning). At the stage
of formalization of the subject area, the base of the
original data is being normalized, i.e., we develop
classification and description: the scale and graduations
and with their use the base of the source data is
being encoded. The result is a database of events
(eventological database) and the training sample. The
stage of cognitive structuring and preparation of the
source data is not formalized and the formalization of
the subject area is fully automated and performed directly
with the use of the universal cognitive analytical
system named "Eidos", which is a software Toolkit for ASC-analysis. Stages of cognitive structurization and
formalization of the subject area of ASC-analysis are
the first steps of data conversion into information and
into knowledge. Subsequent steps: the synthesis and
verification of system-cognitive model, the decision of
problems of identification, forecasting and decision
making, as well as studies of the modeled object by
studying its model will be considered in future articles
The article describes hardware and software specific issues of implementing augmented reality for improving user interface of visualization of a virtual object. It also defines possible future improvements of the subject
The goal of the study is to research experimentally a
pseudo-noise sequence acquisition method for
multicarrier communication systems of MC-DSCDMA,
that allows low hardware requirements and
able to operate in low quality channels. The way of
achieving this lies in using a specially developed
computer model of algorithm in Simulink. The
achieved results have shown high efficiency of the
considered acquisition method in contrast to sequential
search method. The proposed algorithm can be used in
multicarrier systems for acquisition of aperiodic
pseudo-noise sequences in wireless public networks
and in military communication networks
In this article, in accordance with the methodology of SC analysis, we consider particular implementation stages of the synthesis of the numerical model and its analysis. We have also presented the results of the determination of the different states of the processing complex function of various factors on these states and their classification, as well as semantic networks and cognitive class diagrams and factors. On the basis of the analysis we made specific findings and recommendations for decision making at the management level of the region. After execution of the stages of cognitive structuring and formalization of the subject area the further stages of automated SC analysis have been accomplished, the first of which is the phase of the input database of precedents. All these steps are performed directly using "Eidos" universal cognitive analytical system
In the article, the problem of agribusiness industry control is stated, the purposes of control and measure of its success, and also composition of the computerised management system, including control object, controlling system, informational-measuring system and also a subsystem of rendering of corrective actions are considered. What is offered: 1) the control purpose is to consider a raise of quality level of life of the population of region; 2) the capacity of measure of success of control is to consider indexes of quality level of life of the population; 3) numbers and direction of investments can be used as the controlling factor; 4) synthesis and verification of model of agrarian and industrial complex can be performed directly in a cycle of control, based on application of system-cognitive analisys (SC-analisis) and its programmatic tooling - "Eidos" intellectual system; 5) forecasting of evolution of agrarian and industrial complex and production of controlling solutions can be performed on the basis of cognitive model of agrarian and industrial complex with SC-analisis and application of "Eidos" system
The purpose of the research is development of models
and methods of diagnostics of methodical competence
of a teacher. According to modern views, methodical
thinking is the key competence of teachers. Modern
experts consider the methodical competence of a
teacher as a personal and professional quality, which is
a fundamentally important factor in the success of the
professional activity of teachers, as well as a
subsystem of its professional competence. This is due
to the fact that in today's world, a high level of
knowledge of teachers of academic subjects and their
possessing of learnt basics of teaching methods can not
fully describe the level of professional competence of
the teacher. The authors have characterized the
functional components of methodical competence of
the teacher, its relationship with other personalprofessional
qualities (first - to the psychological and
educational, research and informational competence),
as well as its levels of formation. Forming a model of
methodical competence of the teacher, the authors
proceeded from the fact that a contemporary teacher
high demands: it must be ready to conduct independent
research, design-learning technologies, forecasting
results of training and education of students. As a
leading component of the methodical competence of
the teacher is his personal experience in
methodological activities and requirements of
methodical competence determined goals and
objectives of methodical activity, the process of the
present study, the formation of patterns of methodical
competence of the teacher preceded the refinement of
existing models methodical activity of scientific and
pedagogical staff of higher education institutions and
secondary vocational education institutions. The
proposed model of methodical competence of the
teacher - the scientific basis of a system of monitoring
of his personal and professional development, and
evaluation criteria and levels of her diagnosis - targets
system of vocational training and re-training of high
school teachers. Innovation policy is a model of
methodical competence of the teacher, and the main
model of the mechanism of its formation - methodical
activity (in close connection with other activities).
Research methods: analysis of scientific and
methodical literature and best practice methodological
activities in educational institutions, modeling,
methods of the theory of sets and relations, methods of
quality control, methods of multivariate analysis
systems. Methodological bases of research: a
systematic, qualimetric, competence and process
approaches. The work was performed as part of
research projects "Monitoring of the research activities
of educational institutions in the information society"
(№ 16-03-00382) and "Modern information and
educational environment" (16-36-00048) with the
financial support of the Russian Humanitarian
Foundation from 17.03. 2016
Tracking is a vast field of research associated with
navigation, robotics, and virtual environments (virtual
reality). Tracking for augmented reality requires higher
level of precision, increased range of action, as well as
work with a wider variety of input data. It is important
that augmented reality technology requires tracking in
real time, which also complicates the task. Correct
visualization of objects in three-dimensional space
requires six degrees of freedom tracking: three position
values (x, y, z) and three angles (rotation around the
respective axes) to determine the orientation. To solve
this problem, different approaches and sensor types are
being used. In this article, we present a brief history of
the development of tracking technology and analyze the
current approaches to implement the process of tracking
on mass mobile devices such as smartphones and tablet
computers. We also describe some issues in
implementing optical marker based tracking for
visualization of large scale models
