Khramov Dmytro Olexandrovych 

Position: Docent of the Department of Information Systems and Technologies.

Scientific rank: Senior researcher.

Scientific degree: Candidate of Technical Sciences.

Cabinet: 1/79 

Educational work
Docent Khramov D. O. lately teaches disciplines "Data Mining", "Computer Mathematics", "Mathematical Methods and Models" and others.

Scientific activity
The main directions of scientific activity are the dynamics of the orbital and angular spacecraft motion, mathematical and computer simulation, data mining and machine learning. For a considerable time, Khramov D. O. investigated the dynamics of a satellite with a new class of gravitational stabilization systems, the cable system of gravitational stabilization. In particular, he has developed and implemented a method for selecting the design parameters of the stabilization system, ensuring the minimum duration of transients, taking into account the technical feasibility of the parameters, the influence of structural and technological errors, and determine the conditions that provide as soon as possible attenuation of transient stabilization processes. He is the author and co-author of more than 50 scientific publications (including one monograph) and 10 popular science publications.

Other activity
In addition to main scientific activities, Khramov D. O. is actively involved in solving various problems in the field of computer simulation. Thus, in 1996–1997 he developed an algorithm and a program for calculating the temperature deformations of a large space antenna. In 2004–2005 Khramov D. O. participated in the analysis of the causes of the accident with Sich-1M satellite (evaluation of the possibility of satellite collision with the third stage of the launch vehicle). In 2014–2015 he has developed a program of orbital motion and angular motion for the Shepherd spacecraft in the framework of FP7-SPACE-2013-1 LEOSWEEP project. From 2006 to present he has been collecting and analyzing scientific express information using web scraping and APIs. The results of this work are summarized in the monograph entitled "Internet Data Collection using R Language" (ISBN 978-5-97060-459-5).

Khramov D. O. graduated from the Radiophysics Faculty of Dnepropetrovsk State University in 1995. From 1995 to 1998, he studied at the graduate school of Institute of Technical Mechanics NASU and SSAU (ITM). Since 1998, he has been working in the Department of System Analysis of ITM as a junior researcher, researcher and senior researcher (since March 2010). In 2007 he defended his thesis “Dynamics of a Satellite with a Tethered System of Gravitational Stabilization”. In 2012, he received the scientific rank of senior researcher. He began teaching in 2008. Khramov D. O. was a scholarship holder of the National Academy of Sciences of Ukraine from 2000 to 2006. In 2001, he was awarded the National Academy of Sciences of Ukraine for young scientists, and in 2002 – the Presidential Prize for young scientists of the National Academy of Sciences of Ukraine.
