Computer simulation of drilling core

Drilling is a method of exploration and minerals mining. In an era of economy and struggle for energy resources, drilling becomes important in the world economy development. Drilling requires modern high requirements for technical and economic indicators. Drilling requires the use of an integrated approach in the scientific drilling processes study. The drilling model is a complex system.
The model consists of mechanical, chemical, hydraulic, temperature states. Some drilling elements need to be studied at the micro level to achieve results reliability. Thus, the drilling processes study is a difficult task. Solving it with the usual methods is not always possible. Computer modeling is the most promising in this direction. Computer modeling is capable of: 
  1. maximize the research model to the real conditions, 
  2. reduce tool development time and costs, analysis of drilling processes, 
  3. visualize the result.
The LabVIEW programming environment has a large set of add-ons and libraries. One of the additions is the work with graphics, it allows in real time mode to display the change of various geometric shapes depending on the programmable mathematical formulas. This supplement allowed to show the dynamics of the rock cut by the cutters. Figures shows the results of modeling the passage of diamond incisors by rock in two cycles of the program.

Automation of shooting a physical stationary object

The photo-shooting system for the electronic museum's  materials was automated by Moskalyuk Taras - a student of the Computer Science and Technology Faculty, under the my guidance. Automation is performed using the Lego NXT technology, which significantly approximates the end of work and improves the quality of the footage. The new shooting technology allows to expand the possibilities of creating three-dimensional images, up to 180 images per model, without complicating the process of shooting and processing raw materials. Science article was written .

The thermostat in the boiler room

The complex performs automatic control of the boiler houses network  with the ability to monitor and adjust the algorithm through the global network. Consists from hardware and software parts. Includes a thermostat in the boiler room and a manager. Thermostat in the boiler room Hardware: The controller is a PC / 104 processor board (2xRS232, LPT, IDE, Ethernet, VGA, keyboard, mouse). ROM - IDE M-Systems 256 Mb flash disk. Sensors - case external temperature sensor (-40:+30°С); contact feed sensor (-5:+100°С), contact sensor of return water (-5:+100°С); Cabinet temperature sensor in the room (-5:+10°C). All sensors are built on thermistors. Analog input - self-made device (4 analog inputs 8kHz -> RS232, galvanic isolation). Discrete output - self-made device (Parallel port -> 8 relays); Power supply, housing, a set of connecting wires. Optionally - a CDMA modem with a directional antenna, a radio modem, a GSM modem, a wired telephone modem. Software : Windows NT 4.0

Successful passing the exam for an international certificate LabVIEW CLD

January 15, 2018 In Russia, the second certification test of NI LabVIEW CLD (out of three) was successfully passed . From Ukraine there is only one passed -  (but it is proved that he works in the USA). There are 17 certified spesialists in Russia. I analysed that almost of them works in industrial enterprises, and only three - in research institutes. In this context, a person from a typical technical university - is an extraordinary event. Thanks to my family for moral support.
