Aluminum was used as a substrate. It demonstrated the advantage of easier removal process of electrodeposited nanocrystalline nickel from its substrate. Whereas the use of high-purity nickel anode was intended to replace nickel ions, which decreased during electrodeposition. Different peak current densities of 450, 750 and 1000 mA/cm2 were applied. A pulsed current was set at a similar pulse pattern of on-time and off-time of 1 ms and 9 ms respectively. The shorter on-time demonstrated the ability to limit ion deposition, which was related to the formation of finer grains. The off-time arrangement was targeted to ensure that the ion mobility had completely stopped. Higher current density demonstrated a dominant impact on deposits, generating a higher nucleation rate that is related to depositing nanocrystalline nickel. A peak current density of 1000 mA/cm2 produced grain sizes in the nanoscale regime.\u0000Without any additional additive, nanocrystalline nickel was successfully yielded. Investigation of grain size obtained from the 1000 mA/cm2 has been conducted by extracting full width at half maximum peak intensity (FWHM) revealed from X-ray diffraction (XRD) and Transmission Electron Microscopy (TEM) exhibited consistent results of 22 nm and 25.4±3.4 nm, respectively.

The risk assessment process of transport systems has been systematized. This allows business entities in the transport sector to determine ways to prevent and counter information threats and challenges in their activities, both when designing and operating systems for providing transport services.\u0000Verification of the devised methodical approach to information security risk management was carried out on an example of the taxi company «Taxifay N».

When manufacturing sheet parts by bending from a completely elastic sheet, its shape is completely restored after the deformation stops, unlike an elastic sheet. Thus, when producing cylindrical parts by drawing between three rolls, the resulting radius of the cylindrical part will be larger than the calculated one. This phenomenon is evaluated by the coefficient of springing – the ratio of the calculated radius to the one obtained after partial expansion.\u0000When manufacturing conical parts, this approach cannot be applied, because the value of the radius is variable. The article applies the theory of surface bending from differential geometry. The curvature of the line on the surface has two components - normal and geodesic. When the surface is bent, the normal component changes, while the geodesic component remains unchanged. The magnitude of the normal component depends on the angle between the origin of the cone and its axis. So, for a cone with a base of radius R and an angle of 20°, the normal curvature is 0.94/R, and the geodesic curvature is 0.34/R. For cylindrical parts, the geodesic curvature of the cross-section (circle) is zero, so it is not necessary to take it into account.\u0000Usually, adjustment of rolls for the production of conical parts is carried out experimentally. The difference of the proposed approach lies in the elimination of this problem thanks to the decomposition of the curvature of the base of the cone into two components. This allows to calculate the settings of the rolls and thereby reduce their adjustment time. The parameters of the rolls and their mutual placement are calculated for the production of conical parts of the required size, taking into account their springiness.

This paper suggests a methodology that takes into account the appropriate amount of profit and the accumulated amount of royalties in the commercial use of innovative technology. The necessity of taking into account the viability of the transfer of innovative technology as the beginning of its new life cycle was substantiated. The possibility of formalizing this process in the form of an assessment of the sum of the present values of all projected cash flows, taking into account the eligibility criterion and the barrier rate, has been established. We propose an approach, which, unlike the existing ones, consists in allocating a certain period of viability of innovative technology transfer in the life cycle of technology. It is argued that based on the results of technology renovation, it is possible to assess the economic effect of its transfer due to the benefits of implementation and achievement of licensing activity by expanding the number of licensees. We substantiate the possibility of generating profits and royalties to the licensor as the amount of investment that can and should be directed to the development of a fundamentally new or improved technology in relation to the previous one. The transition to a new technology causes an increase in the overall technological level and leads to the formation of a technological gap between the S-shaped life curves of technical systems and, in parallel, forms a new S-shaped curve of a new technological system based on new knowledge.

In this case, there may be losses in case of long queues. To solve this problem, a power spectrum assessment was carried out. The AR maximum entropy estimator has been shown to be more sensitive than the auxiliary Fourier estimator.\u0000Accounting for non-stationarity by spectral methods is possible only through estimation in a sliding time window. Nine diagrams of spectral-temporal analysis of the original series, its increments, and the mixed series of increments were obtained: with default parameters, with small and large windows. Diagrams related to the original series reflect the dynamics of changes in data transmission intensity in the network; they show higher temporal resolution, indicating the presence of high-frequency components (noise) and the presence of low-frequency components (trend). Diagrams with increments describe signals of periodic components; changing the length of the window did not reflect the presence of noise or trend signs. Diagrams with mixed increments show that frequency components are uniformly distributed.
