- Документ1,55 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.

- Документ3D Modeling of the Ball Bearing for the Front Axle Knuckle(Published by Seventh Sense Research Group, 2018) Rami Matarneh; Sotnik, S.; Lyashenko, V.In this work, the questions of ball bearings operation and their constructive features are considered. A 3D model of a detail is created as a ball bearing for for The Front Axle Knuckle. With Solid CAD, a finite-element analysis of the developed detail type is implemented. In the SolidWorks Simulation module, a ball bearing deformation analysis was carried out as a result of the 2000 N impact force. Based on the constructed model and the results of the analysis it was found that the support meets the requirements of strength in its application.
- Документ3D 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.

- Документ3D-биопринтинг воздухоносных путей(ХНУРЕ, 2016) Наконечный, И. М.This work is devoted to the use of 3D-Bioprinting in the field of biomedical engineering, namely the airways bioprinting. Damage to the trachea - a common phenomenon. Known methods of treatments worse than 3D-Bioprinting. To create researchers have resorted to the tracheal tissue engineering. This science is similar to programming code but instead it creates objects from body cells, including, from muscle and cartilage. Just narrowing airways surgically placed into the trachea insert manufactured using 3D-Bioprinting. 3D-Bioprinting is directly relevant to improving and saving lives, as well as the ability to completely transform many of the risky surgical procedures. Работа посвящена использованию 3D-биопечати в биомедицинской инженерии, а именно биопечати дыхательных путей. Повреждение трахеи - частое явление. Известные методы лечения хуже, чем 3D-биопечать. Исследователи прибегли к инженерии ткани трахеи. Эта похоже на программный код, когда создаются объекты из клеток тела, в том числе из мышц и хрящей. 3D-биопечать имеет прямое отношение к улучшению и спасение жизней, а также способна полностью изменить многие рискованные хирургические процедуры.

- ДокументA Diagnostic Model for Detecting Functional Violation in HDL-Code of System-on-Chip(EWDTS, 2011) Umerah, N. C.; Hahanov, V. I.The problem of synthesis or analysis of the components of any system can be formulated by the interaction of its model with input patterns and reactions in a space. This is similar to determining the symmetric difference of the three components – model, test patterns and reaction of the model when the test pattern is applied to it. The distance or relationship between two or more objects in a space can be determined by the well known Cartesian or polar coordinate systems. In case of Boolean variables the Hamming distance has been used to determine how close or far apart are two binary variables of any length. Using Hamming distance results in cardinality or a number; but the beta metric proposed in this paper gives a broader view of how two or more binary variables of any length relates to each other in a cyberspace. And Hamming distance is only a particular case of beta metric. In this paper we define cyberspace as a set of interacting information processes and phenomena which conforms to a predefined metric using computer systems and networks as a vehicle. This paper is organised as follows: In section 2 we discuss the beta metric used in defining the relationship between objects in a space. The analysis of interactive graph of components of technical diagnostics is presented in section 3 followed by a model to search for functional violation in HDLcode in section 4.

- ДокументA generalized algebraic approach to finding rough set approximations and generating logic rules(WIT Transactions on Information and Communication Technologies, 2007) Sitnikov, D.; Ryabov, O.; Titova, O.; Romanenko, O.The rough set concept is a relatively new mathematical approach to vagueness and uncertainty in data. The rough set theory is a well-understood formal framework for building data mining models in the form of logic rules, on the basis of which it is possible to issue predictions that allow the classification of new cases. The indiscernibility relation and approximations based on this relation form the mathematical basis of the rough set theory. The classical topological definitions of rough approximations are based on this relation. Unlike the classical approaches it is possible to define rough approximations in an algebraic way. This paper represents a generalization of the algebraic approach suggested by the authors earlier. We use a set of discrete characteristic functions taking on values from finite sets (not necessarily Boolean values) and operations on them including comparison and Boolean operations, which we call the approximation language. We use the terms \“exact upper approximation” and \“exact lower approximation” to stress the fact that there can exist a variety of approximations but it is always possible to select the approximations that cannot be improved in the terms of the approximation language. We consider the process of generating logic rules based on the exact approximations in the case of arbitrary discrete characteristic functions taking on values from finite sets. Logic rules are naturally obtained from predicate formulae for the exact approximations. The introduced approach allows the generation of logic rules quickly and efficiently since only comparison operations with discrete values and Boolean operations with binary values are used to produce logic formulae.
