Prediction of soil texture distributions using VNIR-SWIR reflectance spectroscopy

2013

Abstract Reflectance spectroscopy provides an alternate method to non-destructively characterize key soil properties. Different approaches, including chemometrics techniques or specific absorption features, have been proposed to estimate soil properties from visible and near-infrared (VNIR, 400-1200 nm) and shortwave infrared (SWIR, 1200-2500 nm) reflectance domains. The main goal of this study was to test the performance of two distinct methods for soil texture estimation by VNIR-SWIR reflectance measurements: i) the Continuum Removal (CR) technique that was used to correlate specific spectral absorption features with clay, silt and sand content, and ii) the Partial Least-Squares Regressio…

El desarrollo de la identidad en la adolescencia y adultez emergente: Una comparación de la identidad global frente a la identidad en dominios especí…

2009

-Juan José Zacarés González: Juan.J.Zacares@uv.es -José Manuel Tomás: Jose.M.Tomas@uv.es -Emilia Serra: Emilia.Serra@uv.es Los objetivos de este estudio fueron examinar el desarrollo y estructura de la identidad a lo largo de la adolescencia y la influencia de las principales figuras de apoyo social y de la autoestima en este proceso. En una muestra de 283 adolescentes entre 14 y 22 años se tomaron dos medi-das del desarrollo de la identidad (identidad global e identidad en los do-minios relacional y escolar), del apoyo social percibido y de la autoestima global. Los resultados indican una maduración en el desarrollo de la iden-tidad, especialmente durante la adolescencia tardía y en el áre…

Prototype selection for the nearest neighbour rule through proximity graphs

1997

Abstract In this paper, the Gabriel and Relative Neighbourhood graphs are used to select a suitable subset of prototypes for the Nearest Neighbour rule. Experiments and results are reported showing the effectiveness of the method and comparing its performance to those obtained by classical techniques.

A Greedy Algorithm for Hierarchical Complete Linkage Clustering

2014

We are interested in the greedy method to compute an hierarchical complete linkage clustering. There are two known methods for this problem, one having a running time of \({\mathcal O}(n^3)\) with a space requirement of \({\mathcal O}(n)\) and one having a running time of \({\mathcal O}(n^2 \log n)\) with a space requirement of Θ(n 2), where n is the number of points to be clustered. Both methods are not capable to handle large point sets. In this paper, we give an algorithm with a space requirement of \({\mathcal O}(n)\) which is able to cluster one million points in a day on current commodity hardware.

Un ejemplo de comentario ramista: el Artificium orationis Ciceronis pro Caio Rabirio perduellionis reo de Pedro Juan Núñez

2015

Se presenta el texto manuscrito del Artificium orationis Ciceronis pro Caio Rabirio perduellionis reo de Pedro Juan Núñez. Se trata de un comentario dialéctico que sigue los principios metodológicos establecidos por Petrus Ramus y que también este autor aplicó al mismo discurso de Cicerón, que publicó en París en 1551. En ese mismo año apareció en Valencia otra edición del mismo anterior a la de Ramus, responsabilidad del alcoyano Andreu Sempere. This paper deals with the manuscript text of the Artificium orationis pro Caio Rabirio perduellionis reo by the Valencian humanist Pedro Juan Núñez. It consists in a dialectical commentary, following the methodological principles established by Pet…

Arte Textil y tradición en la Provincia de Catamarca, Noroeste Argentino

2019

espanolLas tradiciones textiles en la Provincia de Catamarca, constituyen parte de una identidad cultural conformada a partir de elementos muy pujantes provenientes de distinto origen. Estos se traslucen tanto en estilos y tecnicas de piezas de exquisita estetica y calidad. Evidencian ademas, la historia de las industrias y manufacturas textiles que aportaron al desarrollo de esta actividad, considerada por sus habitantes como parte de su idiosincracia que -lamentablemente- con los anos tiende a desaparecer. EnglishThe textile traditions in the province of Catamarca, are part of a cultural identity formed from very vigorous elements from different origins. These are permeated both styles an…

Approximation of functions over manifolds : A Moving Least-Squares approach

2021

We present an algorithm for approximating a function defined over a $d$-dimensional manifold utilizing only noisy function values at locations sampled from the manifold with noise. To produce the approximation we do not require any knowledge regarding the manifold other than its dimension $d$. We use the Manifold Moving Least-Squares approach of (Sober and Levin 2016) to reconstruct the atlas of charts and the approximation is built on-top of those charts. The resulting approximant is shown to be a function defined over a neighborhood of a manifold, approximating the originally sampled manifold. In other words, given a new point, located near the manifold, the approximation can be evaluated…

Superior Performances of the Neural Network on the Masses Lesions Classification through Morphological Lesion Differences

2007

Purpose of this work is to develop an automatic classification system that could be useful for radiologists in the breast cancer investigation. The software has been designed in the framework of the MAGIC-5 collaboration. In an automatic classification system the suspicious regions with high probability to include a lesion are extracted from the image as regions of interest (ROIs). Each ROI is characterized by some features based generally on morphological lesion differences. A study in the space features representation is made and some classifiers are tested to distinguish the pathological regions from the healthy ones. The results provided in terms of sensitivity and specificity will be p…
