Continuous and Discrete Wavelet Transforms Associated with Hermite Transform

International Journal of Analysis and Applications, 2020
In this paper, we accomplished the concept of continuous and discrete Hermite wavelet transforms. We also discussed some basic properties of Hermite wavelet transform.

LDPC coded hybrid discrete cosine transform and Fejér–Korovkin wavelet transform-based SC-FDMA for image communication

Array, 2021
A low-density parity-check (LDPC) coded single-carrier frequency-division multiple access (SC-FDMA) system is proposed for effective image transmission.

Serum Neurofilament Light Chain in Multiple Sclerosis: Superiority of Age‐ and BMI‐Corrected Z Scores/Percentiles Over Absolute Cutoff Values for Prediction of Treatment Response

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Prognostication of disease course and prediction of treatment response in multiple sclerosis is an unmet need. We compared the performance of serum neurofilament light chain Z scores (age‐ and BMI‐adjusted) with absolute concentrations for the prediction of response to disease‐modifying therapy.

Image resolution enhancement using dual-tree complex wavelet transform [PDF]

, 2010
In this letter, a complex wavelet-domain image resolution enhancement algorithm based on the estimation of wavelet coefficients is proposed. The method uses a forward and inverse dual-tree complex wavelet transform (DT-CWT) to construct a high-resolution

Wavelet Transform-Based Signal Denoising in Low-Field NMR

Chinese Journal of Magnetic Resonance, 2018
Low-field NMR often uses permanent magnet. The signals obtained contain high level of white Gaussian noises, and have low signal-to-noise ratio (SNR). In recent years, many denoising methods have been proposed for low-field NMR measurements.

Durability of Response to B‐Cell Maturation Antigen‐Directed mRNA Cell Therapy in Myasthenia Gravis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective We report the 12‐month follow‐up outcomes from a Phase 2 clinical trial (NCT04146051) evaluating Descartes‐08, a BCMA‐directed RNA chimeric antigen receptor T‐cell (rCAR‐T) therapy for refractory generalized myasthenia gravis (MG).

Optimized Time–Frequency Analysis for Induction Motor Fault Detection Using Hybrid Differential Evolution and Deep Learning Techniques

International Journal of Adaptive Control and Signal Processing, EarlyView.
Workflow of the parameter optimization process for ITSC fault detection, applying Differential Evolution optimization and the Smooth Pseudo Wigner‐Ville Distribution for signal processing. The optimized parameters are then used in the failure identification pipeline, which combines the signal processing with a YOLO‐based architecture for fault severity

Edge Detection with Hessian Matrix Property Based on Wavelet Transform [PDF]

Journal of Sciences, Islamic Republic of Iran, 2015
In this paper, we present an edge detection method based on wavelet transform and Hessian matrix of image at each pixel. Many methods which based on wavelet transform, use wavelet transform to approximate the gradient of image and detect edges by ...
