Публікація 1,55 mkm fiber laser with electronic controlled mode-locking(CAOL, 2019) Hnatenko, O. S.; Neofitnyy, M. V.; Machekhin, Yu. P.; Zarytskyi, V. I.; Zhdanova, Yu. V.A projection of an erbium-doped active-fiber laser is offered in this research paper. Mode synchronization method - the nonlinear evolution of mode polarization, is used to ensure the duration of femtosecond pulses. The basis of this method uses liquid crystal controllers polarization, which is controlled by an electrical signal. The proposed scheme and method for obtaining ultrashort pulses are free from the unstable operation of the laser.Публікація 3D modeling, errors sources, internal map, optical detection, surgical navigation system(American Scientific Publishers, 2015) Аврунін, О. Г.; Alkhorayef, M.; Saied, H. F. I.; Tymkovych, M.Several causes of spatial errors in surgical navigation system have been investigated for several systems. These include identification error of the external features used for registration, geometrical distortion in the preoperative images, and tracking error of the surgical instruments. Another potentially important source of error is the patient head position detection retrospectively and concurrent with surgery. The visualization of target zone is carried out according to reference landmark points inside the center of the brain as well as an automatic algorithm for contour recognition (based on 3D segmentation and computer morphometry) was applied to edge the contour. Moreover, the optical navigation system was used to assess the accuracy of determination the position of the surgical instrument inside patient head construction using the "internal map" describing the anatomy of the brain. The major sources of errors occurring in the unit of position detection of the optical navigation system were considered. Furthermore, parts of the errors that could appear were simulated while operating the surgical navigation system. Eventually the research included the possibility of using different filters depending on natural source of noise that was also simulated and analyzed.Публікація 3D-bioprinting system for fabrication of alginate microfibers(АНПРЭ, ХНУРЭ, Издательство «Точка», 2017) Avakian, A.The given work is devoted to the theme of 3D-printing of alginate microfibers with encapsulated stem cells which are used for the nerve regeneration.

I.; Churyumov, G. I.; Denisov, O. G.; Wang, N.; Qiu, J.For more than 50 years, interest to the microwave heating technology has not weakened. In addition to the traditional areas of its application, which described in detail in [1], recently there has been an expansion of technological possibilities for the use of microwave energy associated with the impact of electromagnetic waves of the microwave range on various materials (sintering of metal and ceramic powders) and media, including plasma [2]. One such new direction is the creation of high-power and environmentally friendly sources of optical radiation on the basis of an electrodeless sulfur lamp with microwave excitation [2, 3]. The purpose of this paper is to the further development of the theory and practice of microwave excitation by the electrodeless sulfur lamps, improvement the energy efficiency during energy conversion into the optical radiation and widening the application of new light sources in real practice. The results of the computer modeling of conversion process of the microwave energy into optical radiation energy are presented. The simulation results are compared with experimental data. It is shown that additional use of the solar panels for the reverse conversion of the optical radiation into DC energy with follow-up its using in the circuits of secondary power supply allows improving the energy efficiency of the light source.Публікація A human as a research object for metrology of nonlinear dynamic systems(2017) Machekhin, Yu. P.; Kurskoy, Yu. S.; Prisich, E. Yu.The article presents the results of practical using of the approaches and tools of Metrology of nonlinear dynamic systems (Nonlinear Metrology). They were used for measurement and analysis of dynamic variables of a human body with a regular physical activity. As the analysis tools the intervals of dynamic variables values, measurement portrait, fractal dimension and Shannon entropy are used. The analysis of measurements results demonstrates that the dynamics of measured value is close to deterministic way. This is a characteristic trait of an open system with a self-organization function. The study results can be used for development of athletes training programs.Публікація A matrix electrodynamics as an analogue of the Heisenberg’s mechanics(2008) Gritsunov, A. V.A matrix approach to solving the electrodynamic problems is suggested. The specificity of one is treatment of an electrodynamic system (ES) as an oscillating system with a finite number of the degrees of freedom. The ES is considered as a set of spatially localized so-called partial oscillators (oscillets). Matrices of unit mutual pseudoenergies and unit mutual energies of the oscillators are evaluated. The eigenfrequencies and the eigenfunctions of the ES can be calculated basing on the lumped elements oscillating system matrix theory. A matrix second-order ordinary differential equation is solved for excited potentials of the ES instead of the D’Alembert equation. The main advantage of the matrix electrodynamics is substitution of the solving the partial derivative differential equations by the less computationally intensive linear algebra problems and the ordinary differential equation integration.Публікація A Matrix Electrodynamics: A Similarity to the Heisenberg’s Mechanics?(2008) Gritsunov, A.

Here we report a single-electrode electrochemical system (SEES) using only one electrode not only for a single experiment but also for multiplex experiments based on a resistance induced potential difference. SEESs for a single experiment and multiplex experiments are fabricated by attaching a self-adhesive label with a hole and multiple holes onto an ITO electrode, respectively. This enables multiplex electrochemiluminescence analysis with high sensitivity at a very low safe voltage using a smartphone as a detector. For the multiplex analysis, the SEES using a single electrode is much simpler, cheaper and more user-friendly than conventional electrochemical systems and bipolar electrochemical systems using electrode arrays. Moreover, SEESs are free from the electrochemiluminescent background problem from driving electrodes in bipolar electrochemical systems. Since numerous electrodes and cover materials can be used to fabricate SEESs readily and electrochemistry is being extensively used, SEESs are very promising for broad applications, such as drug screening and high throughput analysis.Публікація Acoustic excitation of electric field in water solution NaCl(Poland, Warszawa, 2019) Аврунін, О.
