ko R.V., Samoylov A.V., Surovtseva O.R., Ushenin Yu.V., Kryuchyn A.A. Improved surface plasmon
resonance sensors with prism type of excitation on polymer basis. Data Rec., Storage & Processing.
2019. Vol. 21. N 3. P. 3–19. — Ukr.
The means related to the improvement of a sensor device on plastic substrate with the prism type
of surface plasmon resonance (SPR) excitation in the Kretschmann configuration and with the scanning
of the incidence angle of monochromatic light aimed for decreasing of production costs and increasing of
sensitivity as well as productivity are considered. It has been shown that application of the laminar poly-
mer substrates after hot press processing, under (180 210 ) temperature and (300 500 kg/cm2) pres-
sure, will provide disappearance of double refraction and high level in SPR sensor sensitivity because of
smoothing surface microrelief. Analysis of the operational characteristics of SPR sensors based on Au
and Ag resonant metallic films is performed. Gold displays higher shift of the resonance angle to changes
of ambient refraction index and is chemically stable. Silver posses narrower resonance curve thus provid-
ing a higher signal/noise ratio of SPR chemical sensors, but has a poor chemical stability. In order to im-
prove sensitivity, measurement accuracy and stability of the SPR instruments operation, two variants for
the active metallic coating preparation are proposed: employment of bimetallic Ag/Au (Au as an outer
layer) structure in 2:1 ratio that combines the advantages of both layers, as well as pure gold film with
subsequent annealing at 120 ºC that smoothes the surface microrelief thus stabilizing the sensors charac-
teristics and increasing sensitivity. The main challenge for increasing of productivity consist in the deter-
mination of the easiest and most cost-effective way to achieve a high degree of parallelization for high
throughput SPR-based analysis. We propose a construction of the sensor in disk format on the basis of the
prism scheme of excitation of SPR in the Kretschmann configuration with optical scanning over angles,
where a planar chip with integrated gratings for the input-output of light was used as a sensor unit. Thus,
the traditional prism and the focusing optics are integrated in a planar sensor unit of the SPR transducer.
The unit is placed on a rotating disk, which increases essentially the number of sensitive elements of a
sensor. Cheap one-time SPR disks can be produced already now in series with the use of available mate-
rials, technologies, and facilities, which opens possibility for the large-scale application. Fig.: 5. Refs: 92

Kalinovsky Ya.A., Boyarinova Yu.E., Khitsko Ya.V. Method of hypercomplex numbers systems
generation for modeling digital reversible filters of 4th order. Data Rec., Storage & Processing. 2019.
Vol. 21. N 3. P. 20–30. — Ukr.
A digital filter is a digital system used to filter a discrete signal. It can be implemented either by
software or by specialized equipment.
The use of hypercomplex numbers for building digital filter structures can provide significant
benefits. Digital filters with hypercomplex parameters have higher speed and better performance in terms
of total parametric sensitivity.
Although in previous works software filter of 3th order structure synthesis algorithms were pro-
posed, in this paper only software filter of 4th order structure synthesis algorithms are considered.
Studies have shown that the expression analysis method for the transfer function denominator
norms of the hypercomplex filter allows you to effectively select the hypercomplex number system,
which has all the necessary properties.
It is shown that only quadriplex number system K and hypercomplex number system ( , , 4)Dk W W
obtained by auto doubling of a double-number system W are suitable for the structures synthesis of
fourth-order hypercomplex digital filters. These hypercomplex number systems allow to get a complete
set of filter transfer function shift operator steps. On the other hand, they have isomorphic weakly filled
hypercomplex number systems. Transition to such systems can significantly reduce the number of real
operations during the filter operation time.
In the work, all transformations and calculations in the hypercomplex domain were performed us-
ing the software module for hypercomplex calculations in the Maple computer algebra framework. This
fact confirms the efficiency of this software module. Tabl.: 2. Refs: 17 titles.
Key words: hypercomplex numerical system, linear convolution, isomorphism, multiplication, bi-
complex numbers, quadriplex numbers, computer algebra system.

Oliinyk A. ., Fedorchenko I . ., Stepanenko . ., Rud M.S. An evolutionary method for solv-
ing the traveling salesman problem. Data Rec., Storage & Processing. 2019. Vol. 21. N 3. P. 31–41. —
Ukr.
A method is proposed for solving the traveling salesman problem on the basis of an evolutionary
approach, and their approbation in the pharmacy business has been carried out by optimizing the opera-
tion of the drug delivery device. A modification of the evolutionary algorithm has been developed,
namely, three methods for initializing an initial population of a simple GA: the standard method (De-
fault), the mixed method (Random), and the mixed optimal (Random optimal). In the developed standard
method, each individual, when generating the initial population, consists of the same gene sequence —
indices of the visited drug packages, arranged in ascending order from first to last. When using the mixed
method, each individual in the generation of the initial population consists of different sequences of genes
— indices of visited packages of drugs arranged in a random order. In the mixed optimal method devel-
oped, each individual, when generating the initial population, will consist of identical sequences of genes,
each of which is the best way among the number of generated mixed paths specified by the user.
Unlike existing methods, a modified GA version allows one to select the initial population initiali-
zation method when solving the traveling salesman problem, which, in turn, allows generating more
adapted chromosomes (chromosomes with better fitness functions) at the initialization stage and thus
improving the results of the algorithm. The proposed modification allows significantly increase the speed
due to the fact that when using the standard initial population initialization method, the initial value of the
calculated fitness function and, accordingly, the distance will be less than when using other initialization
methods, which will allow to more accurately determine the optimum of the problem.
Created software that allows you to change the initial parameters of the genetic algorithm, graphi-
cally observe the process of solving the traveling salesman problem get the result in text and graphic
form. Tabl.: 1. Fig.: 6. Refs: 29 titles.
Key words: optimal path, traveling salesman problem, genetic algorithm, evolutionary algorithm,
minimum distance, graph, C ++, Qt.

system for development processes on management of the aviation forces of Ukraine. Data Rec., Storage
& Processing. 2019. Vol. 21. N 3. P. 42–55. — Rus.

A steady complication and acceleration of the military-technical sphere imposes increased re-
quirements on the system for effective managing of the aviation forces. As the experience of military con-
struction in Ukraine shows that the existing system for managing the development of aviation forces does
not provide an adequate level of efficiency. This is evidenced by the long-term development of the forces,
as well as the absence of any noticeable systemic changes aimed at building the aviation forces to be di-
rected to future. That is, the task of improving the process control system of the development of the
Ukraine aviation forces is relevant. The results of the system analysis and the problem situation formula-
tion with respect to increasing the efficiency of aviation development management are presented. The
difficulties that occur when making management decisions at various government levels, especially at the
level of ministries, the General Staff and headquarters command of the armed forces of Ukraine, are
shown. The occurrence causes are identified and the factors influencing the nature of the problem situa-
tion in the system of development of the Ukraine aviation forces are formulated. On this basis, the man-
agement system improving ways, based on the introduction of automation tools, have been proposed. The
main difficulty here will be the creation of a methodical platform (concept) of special software for a
promising ACS of the Ukraine aviation forces development, where the main features of organizational
management should be taken into account: hierarchy, distribution of decision-making processes and sub-
jectivity of subordinate controlling centers. Fig.: 2. Refs: 9 titles.
Key words: aviation forces, development of forces, development management system, organiza-
tional management, problem situation, hierarchical system, system analysis.

Soboliev A. . Detection of information sources distributing fake information inside global inter-
net network. Data Rec., Storage & Processing. 2019. Vol. 21. N 3. P. 56–68. — Ukr.
One of the important segments of the media system in modern conditions is a set of Internet
sources. The results of sociological research showed that the number of users on the Internet constantly
increases. The most popular network access devices are mobile phones and tablets. This allowed us to
expand the range of services are provided through the global network. Information users from the Internet
increasingly trust it; first of all, the mass media and social media. This function is also used for manipu-
lative purposes to conduct information wars and attacks to give users fake information. The aim of the
media system involves a complex process of bringing information messages in various formats to almost
any person without external participation. At the same time, for the functioning of the Internet media, it is
usually necessary to create and maintain a site that does not require significant financial costs, as for tra-
ditional media. The server can be needed located anywhere in the world, and registration as a mass media
requires an application and a small amount of money. Such conditions of creation and functioning give an
opportunity to provide an external influence on the mass media system functioning on the Internet. Un-
stable sources are responsible for the randomness of the dynamic part on the information network and
play a key role, reflecting (and to some extent generating) the real patterns of network dynamic. This al-
lows identify the most critical information sources. To determine the stability of an information source is
necessary to study the distribution and the number of publications during period of time by determining
the coefficient of the normalized division of the amount of published information by the source. In the
paper is researcher the stability information sources and is the algorithm developed that allows detecting
unstable sources that are used as a tool for information operations to manipulate people's consciousness
during the information wars. Tabl.: 2. Fig.: 4. Refs: 14 titles.
Key words: Hurst index, news agencies, level of stability, information sources, information opera-
tions.

Shylo S.A. Some aspects of practical applications of speckles (Review). Data Rec., Storage &
Processing. 2019. Vol. 21. N 3. P. 69–84. — Ukr.
The review of the works covering the application of methods and ideas of speckles' metrology in
various fields of science and technology is completed. In particular, a special attention is paid to the
analysis of the applications of speckles (bio-speckles) in biology and medicine. A very important area of
the science of speckle is to be mentioned, namely, the speckle fields that develop over time (dynamic
speckles) and arise from moving objects and from scatterers with variable refractive index. The dynamic
speckle methodology allows one to effectively solve problems related to the dynamics of seed change,
fruit rot, parasitic activity and many others. Possibilities for measuring cerebral blood flow through a par-
tially transparent unopened part of the skull of a rat using the temporal contrast method are described. The
results of the measurements can be supplemented by gentle surgical penetration into the rat skull to di-
rectly measure hemoglobin concentration and internal cranial pressure. It should be noted that the Dop-
pler’s effect plays a major role in measuring the parameters of the capillary blood flow with help of ana-
lyzing the behavior of dynamic speckles. Speckle analysis, in dynamics, is successfully used in the study
of processes of microcirculation in the retina, in the study of atherosclerosis plaques on the aorta of peo-
ple in forensic examination, as well as in the analysis of suspensions of human erythrocytes. There are
results on the application of the method of dynamic speckles in endoscopic studies and laser imaging of
internal tissues. The second part of the review is devoted to the analysis of the state of work in the field of
speckle fields obtained from objects of inorganic nature. The speckle dynamics methods are used to
monitor deformations, displacements, vibrations, stresses, oxidation processes, paint drying, evaporation,
and mass loss. Traditionally, non-biological materials are objects with low transparency (inks, metals in
the state of corrosion, cement in the state of hydration, foams, etc.), that imposes appropriate restrictions
on the use of direct light scattering geometry. At the same time, the problems are successfully solved by
modern optical metrology. It is quite obvious that there are a large number of application areas where the
analysis of speckle fields can serve as a useful application in the tasks of appropriate non-contact metro-
logical measurements. Fig.: 7. Refs: 65 titles.
Key words: bio-speckles, dynamic speckles, speckle fields, speckle metrology.

Kuznietsova N.V. A dinamic method for risks evaluation in the financial management system.
Data Rec., Storage & Processing. 2019. Vol. 21. N 3. P. 85–98. — Ukr.
The main definitions and formalization of various types of survival models such as empirical sur-
vival function, generalized linear model, Cox proportional hazards model and its modifications and non-
parametric models are presented for risk assessment. A dynamic method of risk assessment that allows to
assess the risk’s degree and level and also to predict the transition from critical to catastrophic risk by
using of parametric, semi-parametric and nonparametric models based on survival functions has been pro-
posed. The method allows to apply data stratification and separately to simulate different survival func-
tions for different data categories. The method involves the identification of statistically significant char-
acteristics, the development of different survival models and selection of the best model by the set of cri-
teria, testing the hypothesis about the same distribution of risk functions and at finally defined time, the
probability of risk occurrence or probable losses are determined accordingly. Also it includes two devel-
oped by author algorithms that allow prediction of such a time based on the established permissible (criti-
cal) probability of risk occurrence or restriction of possible economic losses, in particular, the moment of
risk transition from permissible to critical or catastrophic (in the defined amount of critical or catastrophic
losses). The algorithm for calculating the moment of transition to the higher risk probability (risk degree)
could be presented in two possible variations. The first possibility is defining time through the calculation
of the derivative of the risk function, which was given explicitly. The second option is to define through
the «probability reserve» (as the speed of probability change). The algorithm for determining the moment
of occurrence of risk’s critical (catastrophic) level by losses is performed as an iterative step-by-step pro-
cedure of transition point search for losses from critical to catastrophic. Tabl.: 1. Fig.: 1. Refs: 12 titles.
Key words: dynamic method, financial risks, survival models, Cox proportional hazards model,
Kaplan-Meier estimation.
