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:  maximize the research model to the real conditions,  reduce tool development time and costs, analysis of drilling processes,  visualize the result. The LabVIEW programming environment has a large se...

The defense of PhD thesis. Successful!

 I successfully defended my Ph.D. thesis in Engineering Sciences in the field of Heat and Gas Supply. My research focused on the application of IT technologies to optimize energy consumption in public buildings.

LabVIEW based mathematical model of building’s heat consumption with non-stationary processes

In this article , the issue of non-stationary processes heat consumption by public buildings for the energy efficiency analysis in heating buildings is being considered. It is justified that the most suitable parameter for adapting the model to the specific building’s conditions is the total heat capacity of everything that is inside the building. As a developed model adaptation’s result there are empirical dependence of total heat capacity has been established for schools. The developed model was used for building’s heating simulation with a cyclically changing load in order to establish the possibility to saving the energy. After passing the preparatory adaptation, the sufficient correspondence of numerical experiments and the practical data on measurement of temperatures are justified. The model was solved using the LabVIEW programming environment. The model is confirmed for schools in Donetsk, for each school, the number of experiments is equal to the number of info...

2D CNC engraver controlled by LabVIEW

Exhibition of scientific works of students "NTTM MAN-2017". Under my leadership, students won the third place among the collective developments. The guys presented the design of 2D CNC engraver controlled by LabVIEW. We used this engraver for summer practice work in my department of computer design and modelling. And we have results! There is a some examples. 

Solar tracker system with dual axis actuators

The aim of this work - researching and creating an automated system for optimal control of the solar pane with current and voltage control. I designed and programmed two hardware-software complexes. The first system located in the field. It is solar panel with controls and sensors.  System transmit the information wireless to the monitoring device. Second system - monitoring device placed in a different location (200 m) and consist from a data receiver and a computer with installed software. Transmitter Reciever

Phonecardiograph

This program are create to find peaks and find a frequency of peaks in Hz. The virtual instrument was developed in LabVIEW. It allows:  Visualizing the recorded signal  Filting the signal from external noise Strengthening the signal Calculation of the duration between the first tones and the one tone duration. You can turn on Advanced mode with fine tuning of low pass filter and numbers of peaks. You can download it and use it for free.

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 .

Multisensor intelligent gas analyzers

The main direction of Computer Monitoring Systems Department (name before 2015) is automated systems for  atmospheric monitoring . The department has worked in this direction for more than 10 years and fulfilled a large number of orders both in the region and in the country. More than 10 employees of the department were involved in these works. Students and graduate students were also involved in this works. About my contribution to the work can be read here , or  here ,or  here ,or  here , although, of course, this is only a small part of the results of the work. Automation of the experiment, design of devices, testing of the finished product - all this would not have been possible without the LabVIEW programming environment. Some history you can read here . It was a great time. Thank you all.

Helicopter

Dean of KITA faculty Alexander Horhordin proposed this task. The current device was provided by the Department of Mechatronics. The micro controller program was developed by a man whom I respect very much - Dmitry Lebedenko. I developed a LabVIEW PID controller program. The result of the work was presented at the NI competition exhibition, a diploma was obtained. I note that it was a very interesting task, debugging and demonstration caused a sensation in the audience. I was pleased to work. And I am glad that I met Dmitry. The stand of automatic control an aerodynamic object is developed for practical application in education on disciplines: "Theory of automatic control in aerodynamic", "Mechatronic and Robotics", "Theory of mechanic". The presented object of the system of aerodynamic management is universal in area of teaching and carries in itself acquainting character with the practical systems. Universality of this setting is in that a s...

Low-cost input-output devices

The Computer Monitoring Systems Department (Donetsk National Technical University) developed stationary system for environmental and atmospheric monitoring. And Department developed the connection of laboratory instruments to a PC. Most of inexpensive gas analyzers, chromatographs, atmospheric sensors and other measuring equipment are equipped with analog outputs. However, ADCs with computer interfaces are expensive. Therefore, the Department has developed low-cost input-output devices that may be of interest to any organizations operating with monitoring and control. RS-232 oscilloscope 1 channel, the frequency of digitization - 14.4 kHz.  Digitalcity  - 8 bits. Measurement range: 0 .. + 5V.
