Damage Identification in Reinforced Concrete Beams Using Wavelet Transform of Modal Excitation Responses

Buildings, 2023
This study focuses on identifying damage in reinforced concrete (RC) beams using time-domain modal testing and wavelet analysis. A numerical model of an RC beam was used to generate various damage scenarios with different severities and locations ...

Timeline analysis and wavelet multiscale analysis of the AKARI All-Sky Survey at 90 micron [PDF]

, 2008
We present a careful analysis of the point source detection limit of the AKARI All-Sky Survey in the WIDE-S 90 $\mu$m band near the North Ecliptic Pole (NEP).

MULTIFRACTAL CROSS WAVELET ANALYSIS [PDF]

Fractals, 2017
Complex systems are composed of mutually interacting components and the output values of these components usually exhibit long-range cross-correlations. Using wavelet analysis, we propose a method of characterizing the joint multifractal nature of these long-range cross correlations, a method we call multifractal cross wavelet analysis (MFXWT).

Joint Time-Frequency And Wavelet Analysis - An Introduction

Metrology and Measurement Systems, 2014
A traditional frequency analysis is not appropriate for observation of properties of non-stationary signals. This stems from the fact that the time resolution is not defined in the Fourier spectrum.

WAVELET ANALYSIS OF PROTEIN MOTION [PDF]

International Journal of Wavelets, Multiresolution and Information Processing, 2012
As high-throughput molecular dynamics simulations of proteins become more common and the databases housing the results become larger and more prevalent, more sophisticated methods to quickly and accurately mine large numbers of trajectories for relevant information will have to be developed.

Poisson inverse problems [PDF]

, 2006
In this paper we focus on nonparametric estimators in inverse problems for Poisson processes involving the use of wavelet decompositions. Adopting an adaptive wavelet Galerkin discretization, we find that our method combines the well-known theoretical ...
