Scientistic schools of the department
Systems of radiocommunications and signal processing
Scientistic director:associate professor Antypenko Ruslan Volodymyrovych. On the department in bounds of scientistic school such directions are developed:
Development of single-dimensional and multidimensional signals (images), reconstruction, restoration, recognition.
Development of digital radiocommunication systems.
Signal processing in powerful mechatronic ultrasound systems.
In modern days of computer technologies it is hard to imagine the world without digital signal transmission – talk through mobile phone, image transferring via Viber, Messenger or other add-ons. Furthermore, as soon as bigger part of information is stored in electron form, it is essential to improve protection systems and access to information. Talking about modern criminalistics world, it can seem that there is nothing to improve because information about fingerprints is already known, but the direction is evolved by modern methods of image recognition.
How to explore useful signal from mixture, where energy of noise is higher in several times than energy of signal?
How to protect access to information with persons signature help? Will somebody be able to falsificate the signature if it is processed on computer?
Even today’s world of medicine is moved forward by new processing algorithms, investigation of biological signals, new methods of inside structure determination. Is it possible to imagine inside structure determination with only help of few electrodes and small device that transmit small current to object and read voltage from the electrodes? Is it possible to find highly unnoticeable changes in human cardiac signal and in such a way prevent health worsening?
Link with the most remote places in the world, with space – it is development of modern digital communication radio systems. How to transmit information, how to receive information, how prevent distortion of the signal during transmission? How to protect data from strangers? That is modern communication systems evolution.
Topicality of data protection question became more urgent because of ‘internet of things’ technology, when big amounts of data are transmitted from sensors through microcomputers to cloud. There the data is processed and control signals are returned to executable mechanisms. The HTTPS protocol usage is not enough to protect channels to internet. Furthermore, part of mobile internet is increasing, as well as free Wi-Fi access points. All these things are increasing risk for users.
In “technologies of radio recon and data protecting” the most common channels are analyzed, considered ways of data interception and ways of defence from illegal access.
One of interesting directions of modern technique and medicine progress is ultrasound cavitation technologies. In borders of scientist direction on ROS department and PGM MMI powerful ultrasound spread in liquids and ultrasound cavitation technologies are observed. The direction is closely related to scientist school.
Powerful ultrasound devices are similar to radioautomatic systems. The main difference is waves spread in environment with nonlinear parameters with high noise level in back-coupling circuits. Herewith ultrasound converters are modeled in systems of electromechanical and electroacoustic technologies.
Why usage of cavitation technologies is needed? Turns out, ‘cavitation bubbles’ in water can wash clothes without powder, disinfect water without chlorine, clean metals without chemical processing etc. Is that possible?
And the answer – yes! You can learn how to do it by studying and working on our department.
