Quantum Sensing of Fast Time-Varying Magnetic Field With Daubechies Wavelets

open access: yesIEEE Access
The waveform of the time-varying magnetic field can be reconstructed by combining the use of quantum sensing technology and orthogonal functions, such as Walsh and Haar wavelet functions, as the control sequences of qubits.

Haar wavelets, fluctuations and structure functions: convenient choices for geophysics

open access: yes, 2012
. Geophysical processes are typically variable over huge ranges of space-time scales. This has lead to the development of many techniques for decomposing series and fields into fluctuations Δv at well-defined scales. Classically, one defines fluctuations

Joint Kalman–Haar Algorithm Applied to Signal Processing

open access: yesRevista de Matemática: Teoría y Aplicaciones, 2012
Under the analysis of signals disturbed by noise, in this paper we propose a working methodology aimed to seize the best estimate of combining Kalman filtering with the characterization that is achieved by applying a multiresolution analysis (MRA) using ...

Estimation of Delay Time in Linear Dynamic Systems Using Wavelets [PDF]

open access: yesالمجلة العراقية للعلوم الاحصائية
 This research explores the use of wavelets in estimating delay time in stochastic linear dynamic systems, as delay time plays a crucial role in diagnosing the system by determining the time interval between inputs and outputs.

Generalized Haar wavelet operational matrix method for solving hyperbolic heat conduction in thin surface layers

open access: yesResults in Physics, 2018
It is remarkably known that one of the difficulties encountered in a numerical method for hyperbolic heat conduction equation is the numerical oscillation within the vicinity of jump discontinuities at the wave front.

HAAR WAVELET ANALYSIS OF CLIMATIC TIME SERIES

open access: yesInternational Journal of Wavelets, Multiresolution and Information Processing, 2014
In order to extract the intrinsic information of climatic time series from background red noise, in this paper, we will first give an analytic formula on the distribution of Haar wavelet power spectra of red noise in a rigorous statistical framework. After that, by comparing the difference of wavelet power spectra of real climatic time series and red ...
