Efficient Time-Frequency Localization of a Signal
International Journal of Digital Multimedia Broadcasting, 2014 A new representation of the Fourier transform in terms of time and scale localization is discussed that uses a newly coined A-wavelet transform (Grigoryan 2005).

Response of Autonomic Nervous System to Body Positions: Fourier and Wavelet Analysis
, 2005 Two mathematical methods, the Fourier and wavelet transforms, were used to study the short term cardiovascular control system. Time series, picked from electrocardiogram and arterial blood pressure lasting 6 minutes, were analyzed in supine position (SUP)

Multi-level Wavelet-CNN for Image Restoration [PDF]
2018 IEEE/CVF Conference on Computer Vision and Pattern Recognition Workshops (CVPRW), 2018 The tradeoff between receptive field size and efficiency is a crucial issue in low level vision. Plain convolutional networks (CNNs) generally enlarge the receptive field at the expense of computational cost.

Advanced Engineering Materials, EarlyView.This study explores a process chain to produce dispersoid‐strengthened CuCr1Zr for applications requiring high strength and conductivity. Using gas‐atomized powder and copper‐plated alumina nanoparticles, additive manufacturing is performed via powder bed based additive manufacturing with green and red lasers, followed by heat treatment.

The curvelet transform for image denoising [PDF]
, 2002 We describe approximate digital implementations of two new mathematical transforms, namely, the ridgelet transform and the curvelet transform. Our implementations offer exact reconstruction, stability against perturbations, ease of implementation, and ...

High‐Rate Deposition and Characterization Study of CoZrO Films for On‐Chip Power Applications
Advanced Engineering Materials, EarlyView.This study introduces a high‐rate reactive sputtering process for CoZrO films, aimed at large‐scale production of on‐chip magnetic components compatible with complementary metal oxide semiconductor (CMOS) fabrication. Characterization of the deposited films reveals that ideal magnetic properties require chemical compositions in a narrow Co:O range and ...

Asymptotic expansion of the wavelet transform with error term [PDF]
Research monograph "The Wavelet Transform" by Prof. R S Pathak and
edited by Prof. C. K. Chui .Atlantis Press/World Scientific (2009), ISBN:
978-90-78677-26-0, pp:154-164, 2014 UsingWong's technique asymptotic expansion for the wavelet transform is derived and thereby asymptotic expansions for Morlet wavelet transform, Mexican Hat wavelet transform and Haar wavelet transform are obtained.

Advanced Engineering Materials, EarlyView.Periodic submicron features are fabricated on 304 stainless steel using single and double femtosecond laser pulses. By adjusting polarization, fluence, and inter‐pulse delay, 1D and 2D nanostructures are formed. Enhanced hydrophobicity and dense surface‐enhanced Raman spectroscopy hotspots enable analyte detection down to 10−10 M with good ...
