The article offers a new architecture of the data bus for digital control system that satisfies the most modern requirements and is designed for use in mechatronic systems. On the physical layer, the new bus is compatible with RS-485 and Ethernet 10/100/1000 Mbps standards. A high level of fault tolerance on the architecture level supports various methods(More)
The results of the treatment of 53 patients with complicated forms of the right side colon cancer are analysed. The radical surgical method with primary removal of the tumor is preferable in this situation. It was possible to perform radical surgery in 69.8 of the cases. In older patients with marked anemia and in patients with decompensated forms of ileus(More)

The article is devoted to the comparison of different hardware implementations of field-oriented control (FOC) for asynchronous motor controller in terms of the control quality, the required amount of FPGA resources and the maximum synthesis frequency. FOC controllers, based on the Kalman filter and the Luenberger filter were considered. This controllers(More)
—In this paper, we propose a construction of full-rank q-ary 1-perfect codes over finite fields. This construction is a generalization of the Etzion and Vardy construction of full-rank binary 1-perfect codes (1994). Properties of i-components of q-ary Hamming codes are investigated and the construction of full-rank q-ary 1-perfect codes is based on these(More)
The purpose of the present study was evaluation of the severity of a purulent process by means of a comparison of clinical and other routine methods with the data obtained by LESA 6 (Laser Endoscope Spectroanalyser) in 84 patients with abscesses caused by odontogenic infection. The obtained results make it possible to claim that there is an opportunity to(More)
