Accepted: 23.02.2018
Abstract
Due to the launch of a large number of small satellites, including the CubeSat class, there is a
considerable increase in the utilization level of nearEarth space by space objects of human origin. At the
same time, computer simulation and geoinformation modeling are only occasionally used by some
organizations, both in Russia and in Western countries, as an analysis and research technique in this
scientific problem. Nevertheless, the prospects of NearEarth space pollution control efficiency
improvement and decision support based on GIS technologies application are obvious. Modern software
tools allow you to develop a fullfeatured GIS that will exceed the capabilities of desktop software solutions
created earlier. In this paper, the authors provide an analysis of the Cesium software library and its builtin
CZML language to describe timedynamic spatial scenes. Although, experimental studies on a prototype of
the geoinformation system of nearEarth space, designed for modeling, visualization and analytical
monitoring of its state have been carried out. The research was carried out within the state assignment of
FASO of Russia (No. 5.6680.2017/8.9).

Accepted: 28.02.2018
Abstract
Currently, the problem of strength and stability of various complex
structures is relevant and paramount for manufacturing, industrial, construction and
other spheres of material production. This article discusses two methods of
determining the eigenfrequencies and visualize the mode shapes, namely: the method
of holographic interferometry and finite element method. Knowing the kind of shape
oscillations and the corresponding frequency, it is possible to significantly reduce the
amplitude of the vibrations change the natural frequencies by introducing additional
elements or replacement of the material. This article presents the determination of
natural frequencies and visualized mode shapes of structural elements with various
configurations are widely used in the industry of hightemperature structural material
of duralumin D16T.

Accepted: 20.04.2018
Abstract
Based on the predeveloped technology for creating spatialtemporal models of
urban development, in this paper, we have developed a database, which represents a
collection of threedimensional models of cultural and historical heritage objects located in
the central part of Tambov (Russia), both existing and completely or partially destroyed.
They include the elements of Tambov fortress of the XVII century (towers, walls, church),
elements of the «Market Square» area (public house, merchant’s rows, tavern) and others.
Currently, the database includes information on more than 200 objects and their elements.
This database can be used by undergraduate, graduate and postgraduate students, tutors and
lecturers. The library of threedimensional models can also be used at creation of multiuser
threedimensional virtual worlds in such software systems as OpenSimulator, Second Life
and others.

composition materials
V.L. Kraynev, A.A. Tikhonov, P.K. Tretyakov, A.V. Tupikin, A.V. Chaplygin
Accepted: 22.04.2018
Abstract
Composition materials are widely used in the aerospace equipment. Requirements to heat
resistance are caused by the aerodynamic heating of surface growing up with increase in flight
velocity of aircrafts. Optical methods can be applied to studying of some characteristics of materials
when modeling fullscale parameters in ground units.
This work is devoted to studying the dynamics of changes of surface temperature and geometry
of sample associated with ablation. Pyrometry and thermal imaging video recording were used for
registration of the process. Information on influence of temperature and flow strength, testing time,
and also recurrence of impact on change of surface deformation rate, ablation and possible
destruction of the samples differing in structure material is obtained. The heatingup rate of the
sample depends on the size and composition of the composite material. For various composite
materials, two kinds of temperature change dynamics were observed – with heating up to
temperatures above the flow temperature, or heating to a temperature slightly below the flow
temperature. For a cylindersphere, a decrease in the longitudinal dimension on the flow axis versus
time can be approximated by a linear function, for a plate the dependence is clearly nonlinear.
Analysis of endurance tests showed that with increase in time the amount of ablation increases
nonlinearly.

apparatus of Rfunctions is proposed. Applied asystem for the Rfunctional of description of the circuit and shown the results of the function at various values of the ratio a. Shows the transition from the organization of separate extreme points of R
functional surfaces to the organization of the linear structure of the skeleton of the zero contour. Here we describe the principle of M
images constructing on the basis of the method of functional voxel modeling (FVM). FVMmethod, is the organizing
principle of symbolicgraphic information, combining the analytic form of the description of a multidimensional model with
a voxel representation of its local geometric characteristics. Selected class of Mimages allows to automate the definition of
the points and lines making a skeleton structure on the basis of delimitation of color transition. Such approach is based on
preliminary representation of graphic information as a functional voxel model and allows to considerably simplify the
computational process of search for solutions. Also we make the comparative analysis of a classical way of construction of
straight skeleton with the offered computer graphic approach.
Visual algorithm for coloring planar graphs
S.V. Kurapov, M.V. Davidovsky, A.V. Tolok
Accepted: 20.04.2018
Abstract
This article addresses a plane graph coloring problem. The authors propose a new visual
algorithm for coloring planar graphs and present a deductive proof of the fourcolor theorem
which is based on the properties of the Klein fourgroup. It is shown that an arbitrary colored
cubic graph has three colored 2factors and the addition of colors is done according to the laws
of the Klein fourgroup transformation. The properties of colored plane cubic graphs are
considered. Two theorems about the existence of a colored disk passing through linked edges
and about edge coloring of a plane cubic graph are formulated and proved in the article.
Moreover, it is shown that the fourcolor theorem can be obtained as a consequence of these
proved theorems. In order to allow edge recoloring in a colored plane cubic graph the authors
introduce a new operation – the rotation of a colored disk. The article provides examples of
solving the problem of planar graphs coloring.

Accepted: 02.05.2018
Abstract
In this paper, we describe the capabilities of the FairCurveModeler software package, used for visualization of highquality curves and surfaces by smoothness criteria, the development of which lasts about ten years. We propose a universal software platform for the visualization of class F curves and development of applicationoriented CAD systems based on the unity of Microsoft Excel VBA, FairCurveModeler software package and computer algebra systems. We demonstrate the use of the software platform for visualization of functional and aesthetic curves in integration with CAD Fusion360. We point out the value of curves for visualization of a qualitative geometry of a product's shape in industrial design. Additionally, we emphasize the requirements for the class F curves' characteristics for the development of a visual purity of shapes in industrial design and for ensuring the positive emotional perception of a product's visual image by a human.
Visualization of the quality (state) of the psychological climate in the team based on the speech interaction acoustic information processing
V.M. Alyushin
Accepted: 11.05.2018
Abstract
Methods for visualizing the state of the psychological climate in a team based on the speech interaction acoustic information processing are proposed. The speaker’s psychoemotional stress level is used as the initial data for assessing the state of the psychological climate in the team. Two main approaches have been identified, aimed at visualizing the personal level of conflict in each member of the team and visualizing the overall psychological climate in the team. To visualize the personal level of conflict, it is suggested to use pie charts that show the level of interpersonal relations of the employee with the rest of the team. To visualize the state of the psychological climate in the team, it is suggested to use a circular graph that allows to display all interpersonal relationships existing in the team. To display the level of personal conflict, different forms of information are used. The quantitative form allows you to display a numerical estimate of the level of conflict in the form of a sector area in the case of using pie charts, or as the length of a segment of the chord of the graph. The qualitative form of information presentation makes it possible to display data on the conflict in the form of a shade of red. The use of two forms of data mapping makes the visualization of information more visual and structured, which increases the efficiency of its operational use. Conducted laboratory testing of the proposed methods of visualization confirmed their effectiveness in solving problems of human factor management.
3D visualization of architecture and metrics of the software
D.E. Namiot, V.Y. Romanov
Accepted: 11.05.2018
Abstract
This article provides an overview of the methods of 3D visualization of software architecture and metrics. Metrics for programs (packages, classes, repositories) form one of the most actively used directions in software engineering. This line of research refers to the analysis of software, and visual analysis here is one of the most frequently used tools. This kind of visualization is usually part of the software quality analysis process. It can be used for training, for refactoring programs, and for integrating (combining) individual components (packages) into complex software systems. Obviously, visualization facilitates and speeds up the process of understanding the structure of software components. This is becoming more and more relevant, because now many opensource software components (what most often integrate into other systems), for example, are large and rather complex software packages. Accordingly, their integration into a new project is a very difficult task. We note that the integration problem becomes even more complicated if there is no access to the source texts of components in questions. In this case, the visual representation of metrics is, in fact, the main element of analysis. Analysis of thirdparty components is not the only area of application. Exactly the same problems arise in corporate development when separate groups work on a large project, which, moreover, can often vary in the composition of performers. In this paper, we consider, for example, the methods of visualization and analysis of the structure of a program in 3D space, which are based on the metaphor of the representation of a software component as a city, which consists of individual buildings that are grouped into districts, etc. We also consider the use of virtual reality for the presentation of software metrics.
A modified algorithm for planarity testing and constructing the topological drawing of a graph. The thread method.
S.V. Kurapov, M.V. Davidovsky, A.V.Tolok
Accepted: 15.07.2018
Abstract
In this article we present a modified algorithm for graph planarity testing with simultaneous construction of a mathematical framework for representing the topological drawing of a plane graph. This mathematical framework is based on the notions of graph isometric cycles and rotation of graph vertices. Obtaining the rotation of graph vertices solve two major problems: the problem of graph planarity testing and the problem of constructing the topological drawing of a planar graph. The system of graph isometric cycles, which is obtained as a result of the algorithm execution, induces the rotation of graph vertices for representing the topological drawing of the graph. The topological drawing is used subsequently for visualization of the plane graph. The topological drawing of the flat part of a graph allows describing the process of planarization by algebraic methods without making any geometric constructions on the plane. The proposed algorithm is based on the reconstruction of the reference cycle and construction of reverse path blocks. The basis for calculation is the selection of the DFStree of the graph by the depthfirstsearch method. Visualization of planar graphs is one of the most important subtasks in addressing a number of topical applications, such as the design of complex products and systems, flat constructions, social network analysis and many others. The computational complexity of the algorithm is estimated as O(m) = f1(m) + f2(m), where m – is the number of graph edges.

F. HernandezCastro, J. MongeFallas, M. MendezMorales, M. ProttiQuesada
Accepted: 25.07.2018
Abstract
For the past fifteen years, the Volcanological and Seismological Observatory of Costa Rica (OVSICORI) in cooperation with American Universities, has been recording crustal deformation data prior a potential earthquake in the Nicoya Peninsula, anticipation which came true on September 5th, 2012 with the occurrence of a 7.6 moment magnitude (Mw) earthquake.
The historical importance of this earthquake is based on continuous monitoring of the Nicoya Peninsula before, during and after the earthquake, making it one of the best documented earthquake in history. The objective of this project is to visualize earthquake data in order to view displacement in two and three dimensions. Another goal is to make the method for showing the behavior of the crust during the earthquake, more intuitive. The target question of the visualizations is only one: to show how the earth's crust moved previous and during the earthquake in each of the affected areas.
We know of no other visualization that use a 3D environment to visualize one earthquake with actual data in this detail level.
A method for visualizing the drawing of a nonplanar graph
S.V. Kurapov, M.V. Davidovsky, A.V.Tolok
Accepted: 15.07.2018
Abstract
In this paper, we consider the issues related to the representation of a nonplanar graph drawing. We propose a new method for constructing a topological drawing of the flat part of a nonplanar graph. The initial information used for the solution is basically the set of graph isometric cycles, which makes it possible to reduce the solution to discrete optimization methods. The necessary concepts and structures for solving the problem of constructing a nonplanar topological graph drawing are considered.
