renal massOBJECTIVE. The purpose of this study was to assess the effect of model-based iterative reconstruction (MBIR) on CT number measurements within small (10-29 mm) low-attenuation renal masses.AJR: American Journal of Roentgenology : Including Diagnostic Radiology, Radiation Oncology, Nuclear ...

For the latter, the absorption would result from acoustic energy transfer into the membrane if the membrane was caused to stretch due to the mass movement. In our work, although we consider damping due to motion of the membrane, the dominant absorption mechanism is due to the MPP and to ...

A quarter car model (lumped mass model) prepared in SAP2000 environment is used to replicate CHR3-type high-speed train. The passage of train over the track structure is represented as a sinusoidal harmonic load. The study establishes that the statistical analysis of the attenuation of the ...
It is suggested that in the frequency range above 200 Hz for this membrane-mass type structure, the sound insulation effect was principally not due to the low-level locally resonant mode of the mass block, but the continuous vertical resonant modes of the localized membrane. So based on such...
(2021) fabricated a sandwich plate-type elastic metastructure by attaching periodic rubber-mass resonators to an orthogrid steel sandwich plate; subsequently, they demonstrated the low-frequency flexural wave-attenuation performance of the proposed structure in a marine power system at an actual-ship ...
(PMD) of more than 0.5 ps/{square root}{square root over ( )}km is undesirable, because of its inducing a mass of polarization dispersion to disable WDM optical transmission; a bending loss increase of more than 40 dB/m is undesirable, because of its inducing variations in transmission ...
Equivalent mass-spring models are developed to theoretically predict the vibration attenuation ranges. Bandgap merging effects induced by the damping of the 3D printed meta-structures are further investigated, and remarkably enlarged attenuation bands are experimentally captured. The metamaterial-based lattice...
