The DTI sets were transferred to an offline workstation for further analysis using the FuncTool diffusion tensor protocol (Advanced Workstation 4.2; GE Healthcare), which contained a preprocessing function to remove echo-planar imaging distortions like scaling, shearing, and translation due to eddy current effects from a diffusion gradient.
"First Cousin Once Removed" echoes "Nobody's Business," Mr. Berliner's 1996 movie about his hilariously resistant father (who appears briefly here, considerably subdued), or "Intimate Stranger," his 1991 attempt to reconstruct his Sephardic maternal grandfather's history.
In OFDMA, a DFE results in better performance than a LE due to its ability to remove past echo ISI.
In this case, the improved DTI methods presented in this paper can also be applied to effectively remove the echo-shifting-induced artifacts in twice-refocused spin-echo DTI.
Microwave power was set to 19.5 mW, and the four-step phase cycling was applied to remove unwanted echoes from measured signal.
That's because the hiss they tried so hard to remove was the echo of the Big Bang, or the Cosmic Microwave Background radiation as it is known. .
Williams had seen an experiment at Bell Labs demonstrating the effectiveness of cathode ray tubes (CRT) as an alternative to the delay line for removing ground echoes from radar signals.
Nilsson's voice in the control room is heard on several songs, instructing the recording engineer to add more echo or remove a voice.
Therefore, it is highly desirable to develop a new empirical approach to effectively remove the spatially inhomogeneous echo-shifting effects resulting from multiple sources.
In [17], echo cancellation is done by an adaptive LMS filter while a linear prediction error filter removes the residual echo and noise.
The procedure was tedious but necessary, especially for removing the UAV echo contaminations.
