    Effect of geometrical and electrical non-identity of monitors manufacturing on accuracy of measurement of beam position has been studied. It has been shown, that even providing mechanical accuracy of monitor manufacturing of about Β±100Β΅m and deviation of electric capacity of electrodes equal to Β±2%, their operating characteristics near the monitor center may differ from each other more than on Β±300Β΅m.Π’ΠΈΠ²Ρ‡Π΅Π½ΠΎ Π²ΠΏΠ»ΠΈΠ² Π³Π΅ΠΎΠΌΠ΅Ρ‚Ρ€ΠΈΡ‡Π½ΠΎΡ— Ρ‚Π° Π΅Π»Π΅ΠΊΡ‚Ρ€ΠΈΡ‡Π½ΠΎΡ— нСідСнтичності виготовлСння Π΄Π°Ρ‚Ρ‡ΠΈΠΊΡ–Π² Π½Π° Ρ‚ΠΎΡ‡Π½Ρ–ΡΡ‚ΡŒ Π²ΠΈΠΌΡ–Ρ€ΡŽΠ²Π°Π½Π½Ρ полоТСння ΠΏΡƒΡ‡ΠΊΠ°.

    No full text
    In the specialized storage rings it is necessary to measure a position of a beam with an absolute accuracy up to 10 Β΅m that corresponds to a relative accuracy about 10⁻³ for the central region of a monitor. The position of a beam is usually measured with the help of electrostatic button monitors. Operating characteristics of a beam position monitor are individual for each copy, are measured on precision benches and approximated by analytical functions. In the paper the various methods of approximation of operating characteristics are considered and the variant allowing one to reduce an error of approximation in tens times in comparison with a traditional method is found.Π’ спСціалізованих Π½Π°Π³Ρ€ΠΎΠΌΠ°Π΄ΠΆΡƒΠ²Π°Ρ‡Π°Ρ… Π½Π΅ΠΎΠ±Ρ…Ρ–Π΄Π½ΠΎ виміряти полоТСння ΠΏΡƒΡ‡ΠΊΡƒ Π· Π°Π±ΡΠΎΠ»ΡŽΡ‚Π½ΠΎΡŽ Ρ‚ΠΎΡ‡Π½Ρ–ΡΡ‚ΡŽ Π΄ΠΎ 10 ΠΌΠΊΠΌ, Ρ‰ΠΎ Π²Ρ–Π΄ΠΏΠΎΠ²Ρ–Π΄Π°Ρ” відносній точності біля 10⁻³ для Ρ†Π΅Π½Ρ‚Ρ€Π°Π»ΡŒΠ½ΠΎΡ— області Π΄Π°Ρ‚Ρ‡ΠΈΠΊΠ°.

    Background. The problem of bone defects replacement is relevant nowadays, that is why many scientists create new synthetic bone substitutes, but the ideal material has not been found so far. The aims of the study: 1) to determine the suitability of the monocortical defect model in the rat femur diaphysis with additional prophylactic reinforcement with a bone plate for assessing the biological properties of implanted materials using the commercially available ChronOS material as an example; 2) to assess of the osteoconductive properties of composite materials based on poly(ethylene glycol)diacrylate and octacalcium phosphate with architecture Kelvin and gyroid types on the developed model. Methods. A prospective study, level of evidence II. A monocortical defect of the rat femoral diaphysis (length 7 mm) was produced under anaesthesia in aseptic conditions and fixed with a polyetheretherketone plate and six titanium screws. In the control group, the defect was left empty. In other groups, blocks of one of three materials were implanted сhronOS and composites of poly(ethylene glycol)diacrylate and octacalcium phosphate with 3D-printed Kelvin and gyroid architectures. After 3 and 6 weeks, the rats were sacrificed, and histological examination of the defect zone was performed. The amount of newly formed bone tissue was histometricly assessed, followed by statistical processing of the results. Results. All rats have reached the planned endpoint, and there were no infectious complications or loss of fixation. Histological examination of the defect zone revealed minimal bone growth in the Control group, rather slow bone formation in the Gyroid group, and statistically significantly more pronounced bone formation in the pores of the materials in the Kelvin and Chronos groups. Conclusions. Bone defect in this model was not spontaneously filled with bone tissue and allowed us to study the biological properties of bone substitutes (the ability to biodegrade and osteoconductive properties). The osteoconductive properties of a composite material based on poly(ethylene glycol)diacrylate and octacalcium phosphate with a Kelvin architecture are higher than with a gyroid architecture and are comparable to that of the сhronOS.ΠΠΊΡ‚ΡƒΠ°Π»ΡŒΠ½ΠΎΡΡ‚ΡŒ.

    Using software support for quantum superposition effects to speed up the solution of the targeted enumeration issue in biometric data when extracting knowledge from a neural network

    No full text
    Background. The continuum/discrete processing of information by natural neurons and artificial neurons is considered. The purpose of the work is to demonstrate the possibilities of unlimitedly long-term support of the effects of quantum superposition by artificial neurons. Materials and methods. As an example, a network of 256 artificial binary neurons (perceptrons) is used. When simplifying the computational complexity of entropy estimates, the state standard GOST R 52633.3–2011 is used. When duplicating data, GOST R 52633.2–2010 is used. The inversion of matrices of neural network functionals with dimensions of 416Γ—256 is performed iteratively according to the criterion of reducing the entropy of the output codes of the neural network. Results and conclusions. It is shown that the support of the effects of quantum superposition with a duration of about 20 minutes on a conventional computer makes it possible to solve the inverse problem of neural network biometrics. It is possible to extract knowledge from the neural network with a confidence probability of 0.97 about the cryptographic key of the user β€œSvoy” and about the parameters of the biometric image of the user β€œSvoy”

    No full text
    AbstractThe development of the next generation of high field superconducting magnet systems demands studies of new technological approach for its internal sections. Several small HTS solenoids (21mm inner diameter, 32 layers) were fabricated by layer-winding technique from SuperPower type SCS-4050 ReBCO wire insulated by polyimide wrapping. Different designs of external and internal joints also were also tested. The highest field generated by HTS coil was 2.4 T in a 10 T background field (total field was 12.4 T) at 4.2K and achieved current density in the coil was 498 A/mm2. The results will be used in development of HTS inner sections for 25 T superconducting magnet

    AbstractThe 1 MVA resistive type single phase AC fault current limiter (FCL) was build and successfully tested by capacitors battery discharge. FCL rated voltage is 3.5kV, current 250 Arms. The 240 m of HTS tape (type SF12100 by SupePower) was used for FCL production. The FCL consists of 8 bifilar coils each wound onto glass-fiber 70mm diameter tube and connected in series. The HTS tapes were additionally stabilized with Cu laminated highly resistive foil. During the tests of separate FCL coils at 380V an excellent limiting performance was observed. Tested FCL coil was switched off after 75ms, the maximum temperature at the HTS tape was less then 230K, the recovery time was about 5 s
