Building Modern Vibration Diagnostics Systems Based on the Frequency-Time Transformations of A Measured Signal

MATEC Web of Conferences, 2016
Basic methods of analysis of vibration transducers signals were reviewed. Continuous wavelet transform, being a time-frequency transform, was found to be an advanced mathematical tool for analysis of vibration signals.

Onasemnogene Abeparvovec in Type I Spinal Muscular Atrophy: 24‐Month Follow‐Up From the Italian Registry

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Onasemnogene abeparvovec (OA) is an AAV9‐based gene therapy for spinal muscular atrophy type I (SMA I). Real‐world outcomes show increased response variability compared to clinical trials, and follow‐up data beyond 12–18 months are limited.

Evaluation of the Potential of Laser Shock Peening Compared with Cold Expansion for Improving Fatigue Resistance of Riveted Lap Joints of Aerospace Grade 7175 Al Alloy

Advanced Engineering Materials, EarlyView.
This study investigates laser shock peening for enhancing fatigue performance of riveted aerospace aluminum joints. A comparative approach with cold expansion combines fatigue testing and synchrotron X‐ray methods. Integrating mechanical testing with residual stress and strain characterization provides insights into how different treatments affect the ...

New results on the continuous Weinstein wavelet transform

Journal of Inequalities and Applications, 2017
We consider the continuous wavelet transform S h W $\mathcal{S}_{h}^{W}$ associated with the Weinstein operator. We introduce the notion of localization operators for S h W $\mathcal {S}_{h}^{W}$ .

The Clifford-Laguerre Continuous Wavelet Transform

Bulletin of the Belgian Mathematical Society - Simon Stevin, 2004
The authors construct certain Clifford-Laguerre polynomials by taking monogenic extensions (higher dimensional Euclidean vector-valued analogues of holomorphic functions) of Laguerre polynomials. One begins with Clifford-Heaviside functions \[ P^{\pm}(x)=\frac{1}{2}\Bigl(1+i\frac{x}{| x| }\Bigr),\qquad x=\sum_{j=1}^n e_j x_j, \] where the standard ...

Innovating Aircraft Repair Processes: The Role of Digitalization in Sustainability

Advanced Engineering Materials, EarlyView.
This research explores how digitalization—by storing detailed non‐destructive testing data in structured DICONDE databases and creating a standard data model of the component—innovates aviation maintenance and repair processes. Coupled with a developed state‐based simulation model, it enables data‐driven, sustainable repair strategies that reduce waste,

Harnessing Fungal Biowelding for Constructing Mycelium‐Engineered Materials

Advanced Engineering Materials, EarlyView.
Mycelium‐bound composites (MBCs) offer low‐carbon alternatives for construction, yet interfacial bonding remains a critical challenge. This review examines fungal biowelding as a biocompatible adhesive, elucidating mycelium‐mediated interfacial mechanisms and their role in material assembly. Strategies to optimize biowelding are discussed, highlighting

Continuous and discrete Bessel wavelet transforms

Journal of Computational and Applied Mathematics, 2003
The authors speak about the continuous and discrete wavelet transforms associated with the Bessel operator, which are defined and studied in the book of \textit{K. Trimèche} [``Generalized harmonic analysis and wavelet packets'' (2001; Zbl 0976.44009)]. The results presented in this paper are given in this book.
