Array Gain for the Case of Directional Noise
The Journal of the Acoustical Society of America, 1967Array-gain computations based on spatial-temporal correlation measurements in the 200–400-cps band and the directionality of the noise field for center frequencies of 112 and 178 cps are obtained. The results derived from spatial-temporal correlation measurements are compared with theoretical values for a directional noise field and vertical receivers,

Low-Frequency Gain Compensation in Directional Hearing Aids
American Journal of Audiology, 2002Hearing aids currently available on the market with both omnidirectional and directional microphone modes often have reduced amplification in the low frequencies when in directional microphone mode due to better phase matching. The effects of this low-frequency gain reduction for individuals with hearing loss in the low frequencies was of primary ...

Adaptation to a direction-dependent visuomotor gain in the young and elderly
Psychological Research Psychologische Forschung, 2008Consistent with the widely accepted notion of separate specification of movement amplitude and direction, it has been argued that there is also a categorical difference between adaptation to novel visuomotor rotations and to novel visuomotor gains.

Direction-finding with sensor gain, phase and location uncertainty
[Proceedings] ICASSP 91: 1991 International Conference on Acoustics, Speech, and Signal Processing, 1991The estimation of the directions-of-arrival (DOAs) of multiple narrowband sources impinging upon an arbitrary array of sensors is discussed. Emphasis is directed to applications in which the sensor locations are only nominally known and the sensor gains and phases may be in error.

Quantifying the Performance Gain of Direction Feedback in a MISO System
2006 40th Annual Conference on Information Sciences and Systems, 2006We consider finite-rate channel-direction feedback in a system with multiple transmit-antennas and single receive-antenna. We address how the symbol error rate performance improves as a function of the amount of feedback. We conclude that when the number of feedback directions is equal to or larger than the number of transmit antennas, transmit ...

Directional Solidification and Melting of Eutectic GaIn
Crystal Research and Technology, 1999Eutectic gallium-indium is studied in a horizontal Bridgman furnace geometry. Differential temperature gradients are applied to solidify and melt the alloy while observing in-situ the interface morphology and the chemical segregation in the melt and in the solid as well. Upon cooling, a wedge-type indium-rich mushy zone develops at the cold wall.

Decision-Directed Automatic Gain Control for MAPSK Systems
IEEE Transactions on Communications, 1975An automatic gain control (AGC) loop is presented for use with M -ary amplitude- and phase-shift keying (MAPSK) systems. The gain control amplifier is regulated by an error signal formed by the difference between the estimated amplitude level and the received amplitude level.
