The solar irradiance is the source of energy used by passive optical remote sensing to measure ground reflectance and, from there, derive properties. Therefore, precise knowledge incoming fundamental for atmospheric correction (AC) algorithms. These algorithms use simulation results a model interactions atmosphere with determine contribution observations. This study presents differences in atmo...

The Virtual Machine Placement (VMP) problem is a challenging optimization task that involves the assignment of virtual machines to physical in cloud computing environment. placement can significantly affect use resources cluster, with subsequent impact on operational costs and In this paper, we present an improved algorithm for VMP, based Parallel Ant Colony Optimization (PACO), which makes eff...

Background Although invasive mechanical ventilation (IMV) has contributed to the survival of preterm infants with extremely low birth weight (ELBW), it is also associated unsatisfactory clinical outcomes when used for prolonged periods. This study aimed identify factors that may be decisive extubation success in very (VLBW) and (ELBW) infants. Methods The cohort included gestational age (GA) &l...

We aim at searching for exoplanets on the whole ESO/VLT-SPHERE archive with improved and unsupervised data analysis algorithm that could allow to detect massive giant planets 5 au. To prepare, test optimize our approach, we gathered a sample of twenty four solar-type stars observed SPHERE using angular spectral differential imaging modes. use PACO, new generation recently developed, has been sh...

In my invited talk ‘The unreasonable effectiveness of Combinatorics in Orthogonal Polynomials I’, (July 1, 1998, 10:30-11:30 local time), at the IWOP ’98, Léganes, Madrid, (organized by Paco Marcellan and Renato Alvarez-Nodarse), I described, for most of the hour, Dominique Foata’s[F1] gorgeous and seminal proof of Mehler’s formula. As I got carried away in the exposition, I replaced the origin...

An improved cloud shadow removal algorithm for high spatial resolution optical satellite data over land is presented. The method based on the matched filter method, which consists of calculation a covariance matrix and corresponding zero-reflectance vector computation function. new additions consist usage an map further evaluations performed performance incorporated in software package Python-b...

El presente estudio tiene como objetivo conocer el valor predictivo de la edad, acompañamiento, y las barreras físicas psicosociales en desplazamiento activo. Participaron un total 1325 estudiantes procedentes centros educativos Educación Primaria Secundaria Comunidad Autónoma Extremadura (España), con edades comprendidas entre los 10-17 años (M =12.1; DT= 1.60). Los cumplimentaron información ...
