Scientific and technical works and projects

There should be mentioned the following contractual and scientific research works carried out for the last three years:

1) In 2014 within the framework of research project “Physical models and tools for 3-D visualization of the interaction of a low-intensity electromagnetic field with micro- and nano-objects of different physical nature and bio-environments (blood)” (No. 0112U000208)  the Department of Electronic Computers accomplished two sections of research in the Scientific Centre Neiro.

The peculiarity of this work is development of neural network methods for restoring initial data taking into account nonlinearity and nonstationarity of objects, the development of neuro-fuzzy models and methods of their training focused on a small training sample as well as the studying of changes in the properties of objects as a result of the complex effects of various physical fields.

2) In 2015 within the framework of the research project “Neuro-Fuzzy Systems for the Current Clustering and Classification of Data Sequences in the Conditions of Their Curvature, Absent and Anomalous Observations” (No. 0113U000361) the department carried out one section of research at the Scientific Centre.

The common fundamental problem, which the project is to solve, is creating new approaches and means of a computer intelligence based on neuro-fuzzy approaches of the first and second types (Type-2) which allow efficient processing of information in terms of its deficit and significant curvature.

3) In 2016-2017 years there has been the contractual work “Development and manufacture of the prototype of the modular cathodic protection station – ISCO” (contract No. 12 / 06-16 dated June 10, 2016) conducted in the Scientific Centre under the general leadership of the senior researcher O. Sotnykov.

4) In 2017 year there has been the contractual work “Creation of scientific and methodological basis of ensuring a survivability of the network systems of information exchange under conditions of an external influence of the powerful microwave radiation” (No. 0117U003916) conducted in Department of Electronic Computers under the leadership of the V. Tokarev.

The aim of this project is to develop the theory of the effect of high-power microwave radiation of pico- and nanosecond duration on radio electronic objects and systems of various functional purposes and its application to ensure their survivability.

The problem of mathematical modeling on the basis of a self-consistent system of equations modeling the process of influence of a powerful electromagnetic field on semiconductor elements, taking into account their topology, was performed. Features and specifics of thermal effect of influence are considered.
On the basis of the analysis an experimental setup for testing the influence of electromagnetic field on a semiconductor element of information-switching systems was developed.
The methods of compression (compression) of microwave pulses of the electromagnetic field for obtaining short pulses with high peak power are determined.

5) In 2018, the contractual work “Creating scientific and methodological bases for ensuring the survivability of networked information exchange systems in the conditions of external influence of powerful microwave radiation” was prolonged (state registration number 0118U000832).

The aim of the research was to further develop the theory of non-stationary processes of excitation of powerful electromagnetic field pulses and conditions of its focusing in free space to increase the efficiency of its influence on the semiconductor element base.
Analytical and simulation methods were used to efficiently emit and receive broadband signals.
An antenna design with an expanding slit was proposed and allowed to create in the equivalent common antenna overlap an interference pulsed electromagnetic field of the bipolar pulse being emitted. The quantitative and qualitative assessment of the effectiveness of the proposed method was carried out.
It is shown that the application of the proposed method significantly increases the range of propagation of impulse signals. Thus, in comparison with the radiation level of the unipolar pulse signal, the propagation distance of the bipolar pulse generated in the overlapping antenna increases 9.5 times, and in comparison with the monochromatic signal – 2.37 times.
