The main contribution of this work is a modal characterization method that is designed specifically for the identification of close vibration modes and which, in contrast with the well established analysis methods, does not require that each resonance region be dominated by a single mode of vibration.
Unlike the popular high frequency resonance technique, this method does not require the information of resonance excited by the bearing fault.
This inexpensive circuit uses a set of high voltage transistors oscillating in tandem and does not require tuning of the resonance drive frequency as the oscillator automatically resonates at the (LC)−1/2 frequency.
A method is proposed for this task which demands a minimum of input data and which, in particular, does not require accurate measurements around resonance.
By contrast, urinary metabolomics using nuclear magnetic resonance (NMR) spectroscopy does not require antibodies, although here too the sensitivity and specificity for detecting early adenomas is less than 65% (Eisner et al., 2013).
Our method for mapping the binding site is general and does not require chemical shift assignment of the enzyme resonances.
Resting-state functional magnetic resonance imaging (RS FMRI) does not require subjects to perform a specific task or stimuli to be applied; it simply requires the participants to keep their mind clear.
2, 49, 59 Usually there is a single or few transient seizures, which associate with acute encephalopathy visualized as posterior reversible syndrome in brain magnetic resonance imaging (MRI) and does not require anticonvulsive treatment in the follow-up.
It should be noted that this method does not require surface plasmon or any other types of surface resonances, although they could certainly help.
Following CT, the 1980s witnessed the appearance of clinical magnetic resonance (MR), a technique of particular importance for imaging patients because it does not require the use of ionising radiation.
