Gravitational waves from eccentric compact binaries: Reduction in signal-to-noise ratio due to nonoptimal signal processing [PDF]
, 1999 Inspiraling compact binaries have been identified as one of the most promising sources of gravitational waves for interferometric detectors. Most of these binaries are expected to have circularized by the time their gravitational waves enter the ...

Signal-to-noise ratio and signal-to-noise efficiency in SMASH imaging [PDF]
Magnetic Resonance in Medicine, 1999 A general theory of signal-to-noise ratio (SNR) in simultaneous acquisition of spatial harmonics (SMASH) imaging is presented, and the predictions of the theory are verified in imaging experiments and in numerical simulations. In a SMASH image, multiple lines of k-space are generated simultaneously through combinations of magnetic resonance signals in ...

Phrases in noise test (PINT) Brazil: effectiveness of the test in children with hearing loss
Brazilian Journal of Otorhinolaryngology, 2021 Introduction: One of the main implications of hearing impairment is the difficulty in perceiving speech sounds, especially in noisy environments. Thus, the frequency-modulated system is considered an important educational tool for children with hearing ...
