Non-Destructive Post-Harvest Tomato Mass Estimation Model Based on Its Area via Computer Vision and Error Minimization Approaches

open access: yesIEEE Access, 2022
Tomato commercialization in Mexican and Latin-American markets is economically affected by three main physical aspects of the fruit: ripening time, size, and mass. Digital image processing combined with mathematical models and machine learning approaches

Mathematical Neural Networks

open access: yesAxioms, 2022
ANNs succeed in several tasks for real scenarios due to their high learning abilities. This paper focuses on theoretical aspects of ANNs to enhance the capacity of implementing those modifications that make ANNs absorb the defining features of each ...

Maximal Regularity of the Discrete Harmonic Oscillator Equation

open access: yesAdvances in Difference Equations, 2009
We give a representation of the solution for the best approximation of the harmonic oscillator equation formulated in a general Banach space setting, and a characterization of lp-maximal regularity—or well posedness—solely in terms of R ...

A Characterization of Best φ-Approximants with Applications to Multidimensional Isotonic Approximation

open access: yesConstructive Approximation, 2004
This paper is a continuation of the previous paper of the same authors [J. Approximation Theory 117, No. 2, 279--300 (2002; Zbl 0557.46020)]. Let \((\Omega,{\mathcal A},\mu)\) be a measurable space. The Musielak-Orlicz norm \(\| .\| _\varphi\) and the Musielak-Orlicz space \({L_{\varphi}=L_{\varphi}(\Omega,{\mathcal A},\mu)}\) are defined as usual [see

Canonical Sets of Best L1-Approximation

open access: yesJournal of Function Spaces and Applications, 2012
In mathematics, the term approximation usually means either interpolation on a point set or approximation with respect to a given distance. There is a concept, which joins the two approaches together, and this is the concept of characterization of the ...
