Hybrid wavelet-gene expression programming and wavelet-support vector machine models for rainfall-runoff modeling

open access: yesWater Science and Technology, 2022
It is critical to use research methods to collect and regulate surface water to provide water while avoiding damage. Following accurate runoff prediction, principled planning for optimal runoff is implemented.

Simulation of Field Theories in Wavelet Representation [PDF]

open access: yes, 1994
The field is expanded in a wavelet series and the wavelet coefficients are varied in a simulation of the 2D $\phi^4$ field theory. The drastically reduced autocorrelations result in a substantial decrease of computing requirements, compared to those in ...

A Model for Yellow Tea Polyphenols Content Estimation Based on Multi-Feature Fusion

open access: yesIEEE Access, 2019
Polyphenols are one of the important ingredients determining the quality of tea, which play an important role in affecting tea quality standards and quality control. At present, NIR spectroscopy technology has been widely used in tea quality detection to

A hybrid wavelet-Lyapunov exponent model for river water quality forecast

open access: yesJournal of Hydroinformatics, 2021
The use of spectral theory and chaos theory on river water quality modeling is reported in a very limited way. This study proposes a wavelet-maximum Lyapunov exponent (WMLE) hybrid model for river water quality dynamics, combining spectral theory and ...

Oversampling of wavelet frames for real dilations [PDF]

open access: yes, 2012
We generalize the Second Oversampling Theorem for wavelet frames and dual wavelet frames from the setting of integer dilations to real dilations. We also study the relationship between dilation matrix oversampling of semi-orthogonal Parseval wavelet ...

A Biorthogonal Hermite Cubic Spline Galerkin Method for Solving Fractional Riccati Equation

open access: yesMathematics, 2022
This paper is devoted to the wavelet Galerkin method to solve the Fractional Riccati equation. To this end, biorthogonal Hermite cubic Spline scaling bases and their properties are introduced, and the fractional integral is represented based on these ...

Parallel Construction of Wavelet Trees on Multicore Architectures [PDF]

open access: yes, 2016
The wavelet tree has become a very useful data structure to efficiently represent and query large volumes of data in many different domains, from bioinformatics to geographic information systems. One problem with wavelet trees is their construction time.

UVB solar radiation climatology for Mexico

open access: yesGeofísica Internacional, 2013
La medición de la radiación solar ultravioleta B de banda (UVB) debe considerarse como una prioridad debido a las implicaciones de este tipo de radiación en la salud pública en todo el país (población nacional total, 108 millones), pero esto no se lleva ...
