Non-parametric linear time-invariant system identification by discrete wavelet transforms
, 2006 We describe the use of the discrete wavelet transform (DWT) for non-parametric linear time-invariant system identification. Identification is achieved by using a test excitation to the system under test (SUT) that also acts as the analyzing function for ...

WE-UNet: A Wavelet-enhanced U-Net framework for radiation dose reduction in chest radiography. [PDF]
J Appl Clin Med PhysAbstract Background Reducing ionizing radiation exposure is a critical goal guided by the as‐low‐as‐reasonably‐achievable (ALARA) principle. Aggressively lowering radiation doses in radiography, however, amplifies image noise, compromising diagnostic quality.

The Haar Wavelet Approximation for the Two-Dimensional Time-Fractional Neuronal Dynamics Model
Fractal and FractionalIn this paper, we developed and constructed the Haar wavelet (HW) for the two-dimensional (2D) time-fractional neuronal dynamics model (TFNDM) with the dynamical electro-diffusion behaviour of ions in nerve cells. The Haar wavelet method is considered in

Human Resource Management, EarlyView.ABSTRACT Employee perceptions of human resource (HR) practices have become a central focus in strategic human resource management (HRM) research due to their impact on individual and organizational outcomes. Recent studies highlight the importance of understanding how these perceptions are formed, what they encompass, and why they vary across employees.

Comparison of the Packet Wavelet Transform Method for Medical Image Compression
JOIV: International Journal on Informatics Visualization, 2023 Medical images are often used for educational, analytical, and medical diagnostic purposes. Medical image data requires large amounts of storage on computers. Three types of codecs, namely Haar, Daubechies, and Biorthogonal, were used in this study. This
