The phrase "attenuation index" is correct and usable in written English.
It can be used in contexts related to measurements or assessments of signal strength, particularly in fields like telecommunications or acoustics.
Example: "The attenuation index of the signal was measured to determine its quality over long distances."
Alternatives: "signal loss metric" or "diminution factor".
A novel decoupling conception Attenuating Diagonal Decoupling and a new index Coupling Attenuation Index are introduced and the system is divided up into two systems with a special structure.
A recently described formulation, the Pressure Attenuation Index (PAI), links arteriolar caliber variations to pressure loss along the retinal arteriolar system.
α represents the attenuation index of free space with a typical value of 2 for single frequency [28].
The hepatic attenuation index was obtained using non-contrast CT images to determine the liver-to-spleen attenuation ratio [ 15].
NAFLD was diagnosed when the liver attenuation index (LAI) value was <5 Hounsfield units using computed tomography.
The liver attenuation index (LAI), derived from the difference between the mean hepatic and splenic attenuation, was used as a parameter for the diagnosis of NAFLD.
The orientation of CH2 groups in amorphous phase estimated from three attenuation indices of 1385 cm−1 band along three directions was very small even for the cold-crystallized, anisotropic PTT sample.
The formation of crystalline phase along three orthogonal directions was followed by changes of three attenuation indices of 1358 cm−1 band which is associated with the wagging vibration motion of CH2 groups in crystalline phase.
Restoring the degraded recto verso images at hand entails solving the system in Equation (1) for ink attenuation indices, blur kernels and sources.
Hence, the ink attenuation indices and the blur kernels are expected to be different, for each source, in the two observations, and for the two sources in a same observation.
A mode-dependent filter is designed to ensure that the filtering error system is stochastically stable and has an H∞ noise attenuation performance index.
