Relative price variability and the Philips curve: Evidence from Turkey [PDF]

open access: yes, 2008
We argue that relative price changes are a key component of the Phillips curve relationship between inflation and output. Building on work by Ball and Mankiw, we propose including measures of the variances and skewness of relative price adjustment in an ...

Estimation of Shear-Wave Velocity Structures in Taichung, Taiwan, Using Array Measurements of Microtremors

open access: yesApplied Sciences, 2021
Near-surface S-wave velocity structures (VS) are crucial in site-effect studies and ground-motion simulations or predictions. We explored S-wave velocity structures in Taichung, the second-largest city in Taiwan by population, by employing array ...

Application of an Automatic Noise or Signal Removal Algorithm Based on Synchrosqueezed Continuous Wavelet Transform of Passive Surface Wave Imaging: A Case Study in Sichuan, China

open access: yesApplied 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.

Ultrasonic guided wave detection of U-shaped pipeline [PDF]

open access: yesMATEC Web of Conferences, 2020
The guided waves in the elbow was analyzed using semi- analytical finite element method, which was used to calculate the dispersion curves, along with the vibration deformation and energy flow density distribution of the elbow cross-section.

Influence of Physical Parameters of Coal Seam on “Cross” Phenomenon of Rayleigh In-seam Wave Dispersion Curve

open access: yesMeikuang Anquan, 2020
Dispersion curves of Rayleigh channel waves may have “cross” between the fundamental and first higher order modes either in the phase velocities or in group velocities in the low frequency band.

A Weighted Average of Multiple Inversions of Rayleigh Wave Dispersion Curve Using Particle Swarm Optimization for Geotechnical Site Characterization

open access: yesIndonesian Journal of Applied Physics, 2023
Shear wave velocity is an important parameter in geotechnical engineering for studying liquefaction, finding bedrock for the basement of a building, and figuring out the presence of subsurface cavities.

Inversion of microtremor recordings dispersion curve based on geological unit

open access: yes矿业科学学报, 2022
The urban microtremor exploration technology is a method that detects urban underground structures by using the weak vibration of environment.The surface wave is dominant in the microtremor recordings, and the surface wave dispersion curve can be ...

Dispersive geometric curve flows [PDF]

open access: yesSurveys in Differential Geometry, 2014
The Hodge star mean curvature flow on a 3-dimension Riemannian or pseudo-Riemannian manifold, the geometric Airy flow on a Riemannian manifold, the Schrodingier flow on Hermitian manifolds, and the shape operator curve flow on submanifolds are natural non-linear dispersive curve flows in geometric analysis.

Tracer Dispersion in Rough Open Cracks [PDF]

open access: yes, 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 ...
