Experimental results obtained with these adaptive notch filters show good control attenuations at targeted gearbox tones, without amplification of other closely located, unreferenced tones.
However, the BESS frequency controller has been modified by introducing a controlled attenuation.
where g i is the gradient magnitude given by d iv 2 + d ih 2 with d i v and d i h being the vertical and horizontal gradient value, respectively, and σ d controls attenuation.
To assess whether the degree of steatosis as determined by controlled attenuation parameter (CAP) measurements correlates with that observed on liver biopsies in a single-center pediatric and young adult cohort.
149 Fibroscan has also recently demonstrated utility in detecting and quantifying steatosis, using a novel attenuation parameter termed 'Controlled Attenuation Parameter' (CAP), which was devised to specifically target the liver using a process based on Vibration Control Transient Elastography (VCTE, Echosens, Paris, France).
For example, the Choi-Williams distribution [5] is obtained for the kernel function where is a scaling factor to control its attenuation rate.
The SSBS functions derive from the sigmoid function and perform an adjustable wavelet shrinkage thanks to parameters that control the attenuation degree imposed to the wavelet coefficients.
Physical property research has identified petrophysical factors, which control the attenuation and velocity of compressional and shear waves in reservoir-type rocks.
In practice, when is fixed, the foregoing makes it possible to control the attenuation degree we want to impose to the data in by choosing, which is rather natural, and calculating according to (4).
A promising mechanism to conserve field stability and to control field attenuation in a waveguide is to inject into the plasma a fast electron beam to excite the natural oscillations of the plasma and additional electromagnetic modes which compensates the losses in the original field.
