Sentence examples for shift frequencies from inspiring English sources

They were implemented using multiband spectral spatial RF pulses to independently modulate the flip angle at various chemical shift frequencies.

However, it requires multiple simulations of the Bloch equations at each stage of the algorithm, and for each relevant set of parameters (e.g. chemical shift frequencies).

Many studies have used Doppler flowmeters based on an analogue circuit design to obtain the Doppler shifts in the signals backscattered from flowing blood; however, some recent studies have mentioned that the analogue Doppler flowmeter exhibits a frequency-response problem whereby the backscattered energy is lost at higher Doppler shift frequencies.

The fundamental forces of evolution— selection, drift, mutation and migration— are the processes that shift frequencies.

In order to confirm that T-tubules are within the Z-T band we compared CARS microscopy data taken for Raman shift frequencies that are close and away from the symmetric stretch CH2 vibration line that is characteristic for lipids.

Power Doppler is the modality of choice for the assessment of vascular pattern (VP) because it is most suitable for the detection of weak signal and low Doppler shift frequencies, it does not alias, it is not angle dependent and gain can be increased without filling the image with noise.

where f d is a Doppler shift frequency.

This allows shift frequency increase further within maximum power budget.

It means that f d τ ≪ 1, where f d and τ are the Doppler shift frequency and the pulsewidth, respectively.

In this study, the energy management algorithm of a multi-mode HEV is optimized using dynamic programming (DP) considering the mode shift frequency and energy losses.

This issue has not been clarified even though ultrasonic pulses may interact with an elastic medium in the monitoring of the Doppler shift frequency.
