Applied Sciences, 2021 Passive surface wave imaging based on noise cross-correlation has been a research hotspot in recent years. However, because randomness of noise is difficult to achieve in reality, prominent noise sources will inevitably affect the dispersion measurement.

Stellar Kinematics of the Double Nucleus of M31 [PDF]
, 1998 We report observations of the double nucleus of M31 with the f/48 long-slit spectrograph of the HST Faint Object Camera. We obtain a total exposure of 19,000 sec.

Tracer Dispersion in Rough Open Cracks [PDF]
, 1998 Tracer dispersion is studied in an open crack where the two rough crack faces have been translated with respect to each other. The different dispersion regimes encountered in rough-wall Hele-Shaw cell are first introduced, and the geometric dispersion ...

Barely visible impact damage identification in a 3D core sandwich structure
Computer Assisted Methods in Engineering and Science, 2018 3D core sandwich structure (3DCSS) is a popular lightweight construction material in the automotive, aerospace and marine industries. However, barely visible low-speed impact-damage (BVLID) may occur in the 3DCSS due to foreign-object-impact that can ...

On the influence of heat transport on low- frequency paramagnetic spin-Lattice relaxation experiments [PDF]
, 1974 In low-frequency relaxation experiments on paramagnetic crystals, placed in liquid helium, often dispersion- and absorption curves are found, strongly deviating from those following from the thermodynamic theory of Casimir and Du Pré.

The Highly Flattened Dark Matter Halo of NGC 4244 [PDF]
, 1996 In a previous paper (Olling 1995, \aj, 110, 591; astro-ph/9505002) a method was developed to determine the shapes of dark matter halos of spiral galaxies from an accurate determination of the rotation curve, the flaring of the gas layer and the velocity ...

Fingerprints of the hierarchical building up of the structure on the gas kinematics of galaxies [PDF]
, 2012 Recent observational and theoretical works have suggested that the Tully-Fisher Relation might be generalised to include dispersion-dominated systems by combining the rotation and dispersion velocity in the definition of the kinematical indicator ...
