Autor: Y. Goranova, I. M. Samnaliev, S. Nikolov, O. D. Zlatev, G. R. Kesov, V. D. Iordanov, V. N. Atanasov

Publikováno v: Bulgarian Journal of Veterinary Medicine, Vol 22, Iss 3, Pp 322-329 (2019)

Access to the circulatory system is essential for continuous monitoring and long-term experimental study. One of the commonest methods for venous access is femoral vein cannulation. The aim of the presented protocol was to elaborate a surgical model

A Figure of Merit for Simultaneous-Multi-Beam Transmit Antenna Arrays

Autor: Anton N. Atanasov, Mark S. Oude Alink, Frank E. van Vliet

Publikováno v: 2022 IEEE International Symposium on Phased Array Systems & Technology (PAST)

We present a simple and useful figure of merit (FoM) with which to evaluate the performance of simultaneous-multi-beam (SMB) transmit (TX) antenna arrays. The FoM builds upon the power-aperture product and effective isotropic radiated power for singl

LOW-GRADE FIBROMIXOID SARCOMА OF LOWER LЕG IN YOUNG FEMALE PATIENT- REPORT OF A RARE CASE

Autor: P. Marinova, S. Popovska, N. Atanasova, V. Ivanova, N. Ramadanov

Publikováno v: Trakia Journal of Sciences, Vol 21, Iss 4, Pp 394-399 (2023)

Low-grade fibromyxoid sarcoma (LGFMS) is a rare soft tissue neoplasm described for the first time by Evans in 1987. It may affect the subcutaneous soft tissues or subfascial space. It usually arises from deeply located soft tissue structures of ext

Reverse Intermodulation in Multi-Tone Array Transmitters

Autor: Anton N. Atanasov, Mark S. Oude Alink, Frank E. van Vliet

Publikováno v: BCICTS
University of Twente Research Information (Pure Portal)
BCICTS 2020

The modern spectral, and thereby linearity, requirements force 5G phased-array transmitter systems to operate at reduced power efficiency, as they can no longer use voluminous filtering. To reduce the linearity requirements of the transmitter, we con
