The extended centroid ofC *-algebras

Archiv der Mathematik, 1990
Let R be a semiprime ring. Then the extended centroid of R, C(R), can be viewed as the center of the symmetric ring of quotients of R, denoted by S(R). If A is a \(C^*\)-algebra then the involution of A extends in a natural way to a positive definite involution on S(A) and, consequently, a partial order is defined in S(A) by taking as a positive cone ...

Bandwidth-insensitive extended centroid frequency-shift method for near-surface Q estimation

Geophysics, 2021
ABSTRACT Seismic waves often are strongly attenuated in the near surface. The measurement and compensation for attenuation are crucial for high-resolution seismic imaging. The quality factor (Q), as a measure of attenuation, is usually estimated by frequency-based methods. We have extended the centroid frequency-shift (CFS) method for

Extended centroid position method in liquid-crystal-based interrogation system for electric-field-modulated Fabry-Perot sensing

Measurement Science and Technology, 2023
Abstract A polarized low-coherence interferometer (PLCI) based on a liquid crystal (LC) wedge is designed, and an associated demodulation method encompassing the tunability feature is proposed for tunable, standalone optical sensing. The application of an electric field to the LC material effectively decreases the birefringence value and
