Motion estimation using common spatial frequencies in synthetic aperture imaging
(I E E E, 1996)
Correlation processing using fully common spatial frequencies of overlapping subapertures is explored for motion estimation between consecutive excitations in multi-element synthetic aperure imaging. Signals derived from ...
Beam space processing for low-cost scanners
(I E E E, 1996)
A subaperture processing technique suitable for low-cost ultrasound imaging systems is presented. The technique is based on multi-element synthetic aperture approach and beam interpolation. A large receive aperture is ...
A noise reduction algorithm in ECG signals using wavelet transform
(Ieee, 1998)
A noise reduction algorithm based on multiresolution orthogonal wavelet transform in ECG signals is discussed. The results are presented for different analysis and synthesis filter coefficients proposed by Vetterli-Herley ...
Using angle information between directed links in coordinating satellite clusters
(Ieee, 2007)
Maintenance and control of microsatellite formations require accurate position sensing and actuation. Accurate three-dimensional relative positional sensing technologies, including differential global positioning satellite ...
Raman and TEM studies of Ge nanocrystal formation in SiOx: Ge/SiOx multilayers
(Wiley-V C H Verlag Gmbh, 2007)
Alternating germanosilicate-siliconoxide layers of 10-30 nm thickness were grown on Si substrates by plasma enhanced chemically vapor deposition (PECVD). The compositions of the grown films were determined by X-ray ...
