Spectral discretizations of the Darcy's equations with non standard boundary conditions
(USFQ PRESS, departamento editorial de la Universidad San Francisco de Quito USFQ, 2018)
Ability of in situ canopy spectroscopy to differentiate genotype by environment interaction in wheat
(Taylor & Francis Ltd, 2021-03)
In recent years, the application of remote sensing techniques is gaining a growing interest and importance in agriculture. Researchers often combine data from near-infrared and red spectral bands according to their specific ...

Point mass perturbations of spectral measures
(Rocky Mountain Mathematics Consortium, 2021-08-05)
Using a generalization of the moment problem and the extremal properties of spectral measures corresponding to the self-adjoint extensions of a regular symmetric operator, we study point mass perturbations of spectral ...
Spectral sensor resolution measurement improvements by temporal analysis

Outer Factor 2-D MA Models for Purely Random Fields and Fields and Wold-Tipe Texture Decompositions
(2007-06-29)
In this paper, we propose a new method to compute the parameters of finite approximations of 2-D MA infinite models associated with purely indeterministic stationary fields, by using spectral factorizations. This method ...
How far can we classify macroalgae remotely? An example using a new spectral library of species from the south west atlantic (argentine patagonia)
(MDPI AG, 2020-12)
Macroalgae have attracted the interest of remote sensing as targets to study coastal marine ecosystems because of their key ecological role. The goal of this paper is to analyze a new spectral library, including 28 macroalgae ...
Absolute Variation of Ritz Values, Principal Angles, and Spectral Spread
(Society for Industrial and Applied Mathematics, 2021-10)
Let A be a d×d complex self-adjoint matrix, X,Y⊂Cd be k-dimensional subspaces and let X be a d×k complex matrix whose columns form an orthonormal basis of X. We construct a d×k complex matrix Yr whose columns form an ...
