Electric-field strengths measured near personal transceivers [PDF]

1993 International Symposium on Electromagnetic Compatibility, 2002
Electric-field strengths were measured at a number of points near 5-W personal transceivers. The points were located on cylinders of revolution with radii of 7 and 12 cm around the antenna. The transceivers operated on four authorized frequencies of 40.27, 162.475, 464, and 823 MHz, and radiated powers of 5, 5, 5, and 3 W, respectively.

Current Tracking Adaptive Control of Brushless DC Motors

International Journal of Adaptive Control and Signal Processing, EarlyView.
In this paper, the current tracking for Brushless Direct Current motors is approached considering uncertainty in the parameters of the motor's model. An adaptive control scheme to compensate electrical parameters uncertainty is proposed without requiring any knowledge of the mechanical parameters.

Analysis of free vibrations of sandwich panel with electrorheological layer based on two models of laminated shells

Журнал Белорусского государственного университета: Математика, информатика, 2020
Based on two models of laminated shells, free low frequency vibrations of a three-layered cylindrical panel with the internal layer fabricated of an electrorheological composite are studied. Both models lead to the same governing equations accounting for

Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.
ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...
