Photovoltaic system faults detection using fractional multiresolution signal decomposition
Electrical engineering & ElectromechanicsIntroduction. In this paper, we present an innovative methodology based on fractional wavelets for detecting defects in photovoltaic systems. Photovoltaic solar systems play a key role in the transition to a low-carbon economy, but they are susceptible ...

Perturbations of the Haar wavelet [PDF]
Proceedings of the American Mathematical Society, 1997 Summary: Let \(m \in Z^+\) be given. For any \(\varepsilon > 0\) we construct a function \(f^{\{\varepsilon \}}\) having the following properties: (a) \(f^{\{\varepsilon \}}\) has support in \([-\varepsilon , 1 + \varepsilon ]\). (b) \(f^{\{\varepsilon \}} \in C^m(-\infty , \infty)\).

Wavelets and Lattice Field Theory
, 2017 When continuous fields are expanded in a wavelet basis, a D-dimensional continuum action becomes a (D+1)-dimensional lattice action on the naively discretized Poincare-patch coordinates of an Euclidean AdS(D+1).

On the Hilbert transform of wavelets
, 2011 A wavelet is a localized function having a prescribed number of vanishing moments. In this correspondence, we provide precise arguments as to why the Hilbert transform of a wavelet is again a wavelet.

Coset Sum: an alternative to the tensor product in wavelet construction
, 2013 A multivariate biorthogonal wavelet system can be obtained from a pair of multivariate biorthogonal refinement masks in Multiresolution Analysis setup. Some multivariate refinement masks may be decomposed into lower dimensional refinement masks.

Signal Estimation Using Wavelet Analysis of Solution Monitoring Data for Nuclear Safeguards
Axioms, 2013 Wavelets are explored as a data smoothing (or de-noising) option for solution monitoring data in nuclear safeguards. In wavelet-smoothed data, the Gibbs phenomenon can obscure important data features that may be of interest.

Simulation of a non‐linear, time‐variant circuit using the Haar wavelet transform
IET Science, Measurement & Technology, 2022 Wavelet theory has disentangled numerous complexities, including those pertinent to transient and steady‐state responses of systems, when Laplace and Fourier transforms face insoluble obstacles. Reactive linear components (e.g.
