Optimal quadrature for Haar wavelet spaces [PDF]

open access: yesMathematics of Computation, 2003
This article considers the error of the scrambled equidistribution quadrature rules in the worst-case, random-case, and average-case settings. The underlying space of integrands is a Hilbert space of multidimensional Haar wavelet series,

Assessment of Haar Wavelet-Quasilinearization Technique in Heat Convection-Radiation Equations

open access: yesApplied Computational Intelligence and Soft Computing, 2014
We showed that solutions by the Haar wavelet-quasilinearization technique for the two problems, namely, (i) temperature distribution equation in lumped system of combined convection-radiation in a slab made of materials with variable thermal conductivity

Feedback Control Method Using Haar Wavelet Operational Matrices for Solving Optimal Control Problems

open access: yesAbstract and Applied Analysis, 2013
Most of the direct methods solve optimal control problems with nonlinear programming solver. In this paper we propose a novel feedback control method for solving for solving affine control system, with quadratic cost functional, which makes use of only ...

Non-parametric linear time-invariant system identification by discrete wavelet transforms

open access: yes, 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 ...

Explaining Variability in Employee Perceptions of HR Practices in Strategic HRM Research: An Integrative Review and Future Outlook

open access: yesHuman 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.

Interleaved Diffractive Networks for Information Transfer Through Random Diffusers

open access: yesLaser &Photonics Reviews, EarlyView.
This work presents a cascaded diffractive optical network that enables information transfer through random, unknown diffusers using passive, interleaved structured layers that mitigate scattering without digital computation. A hybrid optical‐digital version further improves robustness and reconstruction fidelity under distortions, with both simulations
