In our antenna model, we assume that an antenna can work in two modes: omnidirectional mode and directional mode.
In [15], the problem is alleviated by assuming that the gain in both omnidirectional mode and directional mode is the same.
Theoretical results are presented for the mode, frequency, and directional dependent variations in energy velocity with respect to stress.
Here, we perform a sequence of multiple loading modes on the same human brain specimen – simple shear in two orthogonal directions, compression, and tension – and characterize the loading-mode specific regional and directional behavior.
Vehicles are equipped by one transceiver that can work in omnidirectional and directional modes.
The present study tested this assumption by measuring the head-orienting behavior of bilaterally fit hearing-impaired individuals with their microphones set to omnidirectional and directional modes.
The purpose of the present study was to examine the head movements of bilaterally fitted HI listeners in both omnidirectional and directional modes while undertaking an orientation task.
Directional microphones, in contrast, have not been shown to improve general localization ability; the same study found that mean left/right error was equivalent across omnidirectional and directional modes.
Both the ME voltage coefficient and the corresponding phase suggest that the ME effect is omni-directional around the fundamental extensional mode of the PZT ring and directional around the third extensional mode with different magnetic field orientation.
This paper focuses on the effects of anisotropy on the natural frequencies and directional properties of the modes of circular rings of rectangular cross-section, made from crystalline silicon.
