The goal of this work is the speedy incorporation of the cryoimaging into visual analytics for practical medicine and biology, and creation a single solution for both managing visualization and segmenting the data of cryoimaging in natural colors. In this paper we used the quantization and indexing of the natural colors for the cryoimaging data as a basis for solving two formulated in the article problems: 1) three times more memory for cryoimaging data, than for the same indexed data using palette; 2) the transparency control of real tissues which are heterogeneous in color.
We showed here that: 1) when using a palette of 256 colors, built using LindeBuzoGray method, instead natural colors of femail dataset of Visible Human Project (VHP), the image quality losses are not significant (PSNR=44  invisible for human eye); 2) 3D image quantization is not only the way to reduce dataset size – they showed about twice performance improvement (in frames per second, fps) compared with the visualization of threechannel raw data, and the best performance was achieved by loading the whole dataset as a single block (up to 108.9 fps for the dataset and GeForce GTX 680); 3) the high resolution of cryoimages makes rendering artifacts invisible to the human eye; after indexing the image quality is enough and trilinear interpolation becomes unnecessary, because it increase PSNR up to 45.5 db only, but programmable trilinear interpolation leads to twice downfalls the performance; the direct use of indices interpolation via hardware gives a the loss of the image quality which noticeable to eye; 4) quantization of natural colors give us good possibilities in the both opacity control and segmentation; a method for segmenting (classifying) a voxel tissue according to the normalized histogram of the indexed colors (NHICmethod) from its neighborhood is proposed and investigated (on the femail dataset from VHP); its possibilities were investigated in the range of both the neighborhood radius and the decision making threshold.

Accepted: 11.12.2017
The paper presents the results of a study on identification of unreliable financial statements of enterprises in the real sector of the economy.
A wide range of research methods was used within the framework of a systematic approach to the process of identifying falsification of financial reports, such methods as interconnection of reporting indicators, elements of financial analysis (horizontal and vertical analysis of reporting indicators), modernized financial indicators of Beneish, analysis of time series of reporting indicators using Shewhart (control) charts.
Such an approach made it possible to identify distortions associated with consideration of interests on loan agreements and their undue reflection in financial reports, which, in turn, caused the recognition of such reports as inaccurate.
Visualization processes that were applied not only by the analysis of the research results, but also at intermediate stages of financial report data processing and further research planning played an important role in the preparation of this article.
LABORATORY APPROBATION OF A NEW VISUALIZATION FORM OF HAZARDOUS OBJECTS CONTROL OPERATOR CURRENT PSYCHOEMOTIONAL AND FUNCTIONAL STATE
M.V. Alyushin, L.V. Kolobashkina
Accepted: 02.12.2017
The paper suggests a new form of visualization of the current psychoemotional and functional state of operators for managing dangerous objects. Integral assessment of the current psychoemotional and functional state of the operator is carried out on the basis of the registered bioparameters analysis. These bioparameters characterize the current functioning of its cardiovascular system, the respiratory system and the peripheral nervous system. Registration of these bioparameters is carried out on the basis of passive remote noncontact technologies, typical of which are acoustic and optical technologies.
The proposed form of visualization allows the display of both the indicators reached within a certain time interval and their change in dynamics, which significantly expands the scope of its possible application. The considered form of visualization also makes it possible to display the trends of a possible change in the state of the operator in the short and longterm perspectives.
Experimental approbation of visualization technology in solving problems of optimization of educational and training sessions, as well as in developing methodological tools for assessing the level of acquired professional knowledge and in adapting educational process to groups of various specializations, confirmed its high efficiency.

A.A. Glîbà, O.A. Ulchitskiy, E.K. Bulatova
Accepted: 02.12.2017
This paper is based on the PhD research work “Supporting the Use of Parametric Design in Architecture”. One of the key factors in design and analysis of empirical research in parametric computeraided design in architecture is the comprehensive and justified measurement metrics of parametric modelling effectiveness. Introduced studies agree about the same thing that some of the parametric design systems are parametric rules and strategies. There is an obvious gap between traditional design principles and methods, rules of algorithmic modelling. For understanding of this gap there is an algorithm identification along with its parametric research, that allows to encrypt ideas in the language of textual and visual type of programming. This paper describes the evaluation criteria, methodology and application procedures for measuring the effectiveness of parametric modelling and design ideation, which was developed as a part of the comparative study (ongoing PhD research work) titled “Supporting the Use of Parametric Design in Architecture”.

Accepted: 19.11.2017
This article gives an overview of the Russian and foreign literature sources, about the problem of the synthesis of models of spatial objects from their images, available on various information storages (projection images in paper and electronic form). The problem of model synthesis is the key in information technology, since it is the geometric 3D model that underlies the solution of applied graphics problems.
The problem of synthesizing a 3D model of an object from the set of its 2D projection images belongs to the difficultly formalizable inverse problem of engineering geometry and has not been fully implemented either algorithmically or programmatically. For the first time the problem was formulated and posed as a scientific problem in the 60s of the 20th century in the USSR.
The chronology and variants of the solution of the task are given.

COMPACT VISUALIZATION OF DYNAMIC PARAMETERS IN MONITORING AND CONTROL SYSTEMS
V.V. Guchuk
Accepted: 05.11.2017
The paper describes the technology of representing informative dynamic parameters in interactive systems for monitoring and managing complex scientific and technical objects. It allows to give the most complete and adequate view of the state of the managed system, and at the same time provide the humanoperator with the ability to perceive the information presented in terms of making sound and effective operational solutions.
It is proposed to construct a class of images similar to the known dynamic spectrograms, but with a wider representation capabilities. These composite images are formed in two stages. At the first stage, the signal segments are described as functions of one variable (diagrams). Here, the expansion of the presentation capabilities is achieved by applying various descriptions (spectrogram, histogram). Diagrams are represented as a vertical segment. Amplitude is encoded by the brightness of the screen point. At the second stage, compilation of images from the columndescriptions of a certain type is performed, that is, a consecutive arrangement of columns on the screen. Here, the extension of presentation capabilities is also based on the introduction of diversity  the use of different types of compilation. For example, the abscissa value (that is, the column number) corresponds to the value of the determining parameter of the signal source (the degree of wear of the cutting tool, the magnitude of the load, the output power). Examples of the representation of various parameters are given. The proposed class of composite images allows you to compactly represent large data sets.
The humanmachine interface can be designed to represent a wide variety of signals. Therefore, providing not only compactness, but also the efficiency of presentation requires a wide variety of descriptions and types of compilation. They should be selected depending on the parameters and signals analyzed. With a successful choice, visual analysis is greatly facilitated, and it becomes more productive.

A number of demonstration experiments on the study of the structure of the air flow over a rectangular obstacle, based on a combined approach using PIV method to restore the overall picture of an air flow over an obstacle, and its verification on the basis of numerical calculations. As a result of research carried out on the basis of PIV method, it was found that the air flow can be conditionally divided into regions, reflecting qualitatively its typical features: the origin of the formation of the separation, the separation region of maximum vertical scale and flow joining region. A step by step verification of the results of numerical simulations with the ANSYS FLUENT application based on the results of experimental measurements of the spectral characteristics of turbulent fluctuations were carried out. A selection of the optimal numerical scheme for reproducing the experimentally observed flow patterns included calculations based on SAS (Scale Adaptive Simulation) turbulence model and DES turbulence model, with the central scheme of numerical differentiation. Using SAS turbulence model has led to a distortion of the qualitative picture of flow, namely to the emergence of a false separation of the boundary layer, the characteristic frequencies in the spectrum of velocity fluctuations were much too high. Presumably the correct calculations made in the framework of SAS turbulence model are impossible due to the use of a highly anisotropic (elongated in the direction perpendicular to the main flow) computational grid. Comparison of numerical calculations with experimental results have shown that the physical process of the flow over an obstacle can be optimally modeled in a threedimensional formulation using DES turbulence model with the scheme of central numerical differentiation.
THE MULTIAGENT PARADIGM OF RANGE IMAGE SEGMENTATION
Khaldi Amine
Accepted: 22.10.2017
In this work, we presente and compare three methods for edge detection applied to range images based on deformable models. We will apply a classic active contour, level sets then an adaptive active contour. Despite the good experimental results on the simple objects, we note that the adaptive and classical snake methods have a few limitations. The adaptive and classical snake cannot detect discontinuities in curvatures and some items do not always converge. The level set method is very efficient for segmenting range images with curvature and with complex forms. Finally we propose a multiagent system approach for segmenting range images.
A SURVEY OF VISUALIZATION TECHNIQUES OF ALGORITHMS ON GRAPHS
D.S. Gordeev
Accepted: 31.07.2017
The paper describes methods of visual representation of graph algorithm behavior. Several points of interests are an ability to configure input graph by user, an ability to configure input algorithm by user and an ability to configure visual effects for algorithm visualization visualization.
Existing visualization systems often use automatically generated graphs as input parameters and at the same time input algorithms are fixed by design of a system. Often visualization system are presented as catalogs where some fixed algorithms can be visualized for different input graphs. Usually if there is need to append a system with new algorithms then it's necessary to develop whole visualization from the beginning. Also continuous animation looks interesting addition to visualization technique in order to create smooth image transitions on output devices and to attract attention of user.
Also this paper considers widely used algorithms visualization techniques such as eventdriven approach and datadriven approach. Also interesting characteristic is configuration of drawing of graphic primitives for graph visualization process in order to prepare user to following images.
COMPUTER VISUALIZATION OF CONIC CURVE PASSING THROUGH THE IMAGINARY POINT AND THE IMAGINARY CONCERNING DIRECT
V.A. Korotkiy
Accepted: 23.07.2017
The proposed algorithms graphical computer simulation of the second order curves, given an arbitrary set of real and imaginary points and tangents. Developed a set of software for geometrically accurate construction of the main axes, asymptotes, foci and subsequent visualization of the conic sections, given both real and imaginary elements. To solve the problem used projective synthetic geometric algorithms, totally eliminating the need to perform any algebraic calculations. An example visualization of a conic passing through the valid point relating to the four imaginary straight lines.
Developed visualization tools used to study quadratic Cremona convert the specified imaginary fundamental points (Fpoints). Birational (cremonesi) conversion is an effective machine design the smooth curves and dynamic twodimensional lines. The simplest birational mapping is a quadratic mapping of flat fields with each other, which is determined by using two pairs of projective bundles of straight lines with vertices in the fundamental points. In the projective definition of the quadratic conformity can participate two pairs of imaginary complex conjugate of Fpoints as double points of elliptic involutions on the lines associated with a valid pair of Fpoints. In this case, the imaginary projective bundles cannot be used to construct points corresponding to a quadratic transformation. The paper proposes a generic constructive algorithm for corresponding points in a quadratic transformation, given both real and imaginary Fpoints. The algorithm is based on the use of assisted projective matching and transformation Girst centered in one of the valid Fpoints. The possibility of representation for the quadratic map with imaginary Fpoints is the product of collineation and Girst transformation.

S.R. Abulkhanov, N.L. Kazanskiy, Yu.S. Strelkov
Accepted: 20.07.2017
We propose a technique for conducting a comparative analysis of locomotive headlight designs with different light sources. The technique involves a number of stages of numerical analysis for modeling the impact of vibrationrelated deformations characteristic of the locomotive in motion on the reliability and photometric characteristics of the headlight. The main stages of this analysis are: creating a 3D model of the analyzed lighting device; determining the natural frequencies of the device based on the use of ANSYS Workbench program; modeling deformations of the device at its natural frequencies; analysis of the contribution of deformations of components in the largest deformation of the entire device; based on the calculation of the ray tracing the analysis of functioning the lighting device in conditions of the greatest strain. Based on the technique proposed, we investigated the different designs of the locomotive headlight: 1) with bulb as light source; 2) with LEDs as light source; 3) with LEDs mounted on a perforated substrate; 4) with LEDs on the perforated substrate reinforced with ribs. Thus, we offer a solution to the problem of joint analysis of searchlight vibration loads and quality of directivity diagram formed by the headlight. A key element of the analysis is the use of dynamic visualization of the vibration oscillations for the headlight and of formed (under a maximum distortion of the searchlight structure) light beam.

V.L. Averbukh, M.O. Bakhterev, D.V. Manakov
Accepted: 07.07.2017
In this paper approaches to the evaluation of metaphors and view of Software Visualization systems are considered on the examples of representation of call graphs and execution traces of parallel programs. Execution traces map the dynamics of the certain program executions. Visualization and “replaying” of execution traces are important elements of debugging systems. The visual presentations of the Call Graph are widely used in the systems parallel program performance tuning systems. The visualization metaphors using to depict call graphs and execution traces are surveyed. “Traditional” (for example the City metaphor) and new (for example the Brain metaphor) metaphors are considered. The validity of visualization techniques is studied on basis of analysis of metaphor properties. It is important to understand what objects may be represented with one or another metaphor. The possibility of the visualization metaphors (for example City and Molecule metaphors) to represent large and huge volumes of data is analyzed. Shneiderman’s scheme is considered as method of evaluation of visualization. B. Shneiderman presents seven high level users needs that an information visualization application should support. (Overview, Zoom, Filter, Detailsondemand, Relate, History, Extract) The use of the Schneiderman's scheme presupposes the existence of large structured data volumes. Further some other approaches to the evaluation of metaphors and views are considered. Among them are the criterion mental structure conservation and the evaluation of system implementation efforts. The problems of Software Visualization for parallel computing are observed. The formalization of parallel computing and in particular performance tuning may be useful to resolve problems of Software Visualization.

The present article opens a series of publications related to the application of Photonics to visualize results in experimental physics. This report is devoted to the analysis of experimental results using methods of coherent laser holography for common tasks event detection in the tracking detectors of elementary particles. Considers the possibility of threedimensional holographic imaging and optical correlators with coherent laser light. It justifies the use of holographic systems for recognition of events recorded in tracking detectors at the stage of primary selection on the form or intensity of the signal correlation. The expediency of transformation of the laser radiation coherence and the transition to optical imaging and processing by radiation with partial spatial coherence is justified.

An approach to the visualization of flow parameters in branched systems (for onedimensional case) is described. It is proposed to consider all the flow parameters as a function of a single variable  the distance from the start point of the system. In this case, functions, that are continuous in the branching points, can be presented as a treelike structure, that gives us a convenient way to perceive all the spacetime pictures of the flow.
The proposed approach is applied to the visualization of flow parameters obtained by solving the water hammer problem in branching pipes. The mathematical model of water hammer is described, the results of water hammer modeling are presented. The visualizations of the data obtained are provided in the form of snapshots and movies.
