Atmospheric factors, such as clouds, wind, dust, or aerosols, play an important role in the power generation of photovoltaic (PV) plants. Among these factors, soiling has been revealed as one of the most relevant causes diminishing the PV yield, mainly in arid zones or deserts. The effect of soiling on the PV performance can be analyzed by means of I–V curves measured simultaneously on two PV panels: one soiled and the other clean. To this end, two I–V tracers, or one I–V tracer along with a...

Efficient query processing in spatial databases is of vital importance for numerous modern applications. In most cases, such processing is accomplished by taking advantage of spatial indexes. The xBR+-tree is an index for point data which has been shown to outperform indexes belonging to the R-tree family. On the other hand, Solid-State Drives (SSDs) are secondary storage devices that exhibit higher (especially read) performance than Hard Disk Drives and nowadays are being used in database...

Membrive Pérez, Verónica
Existe una tradición no revelada ni estudiada relacionada con la presencia de viajeros irlandeses en España, la cual posee características propias y se aleja de la posición de superioridad cultural o del enfoque colonial que era una característica común en las narrativas británicas sobre sus encuentros con el país. El escritor irlandés posmoderno Aidan Higgins (1927?-2015), quien residió en España en la década de 1960 en busca de inspiración, dedicó su novela Balcony of Europe (1972) a los...

This paper describes a parallel version of the PC algorithm
for learning the structure of a Bayesian network from data. The PC
algorithm is a constraint-based algorithm consisting of fi ve steps where
the first step is to perform a set of (conditional) independence tests
while the remaining four steps relate to identifying the structure of the
Bayesian network using the results of the (conditional) independence
tests. In this paper, we describe a new approach to parallelization of the

In this paper we propose an algorithm for answering queries in hybrid Bayesian networks where the underlying probability distribution is of class MTE (mixture of truncated exponentials). The algorithm is based on importance sampling simulation. We show how, like existing importance sampling algorithms for discrete networks, it is able to provide answers to multiple queries simultaneously using a single sample. The behaviour of the new algorithm is experimentally tested and compared with...

Arcoya, David, Carmona Tapia, José|||0000-0001-9319-4382
We study the multiplicity of critical points for functionals which are only differentiable along some directions. We extend to this class of functionals the three critical point theorem of Pucci and Serrin and we apply it to a one-parameter family of functionals $J_\lambda$, $\lambda \in I\subset \mathbb R$. Under suitable assumptions, we locate an open subinterval of values $\lambda$ in $I$ for which $J_\lambda$ possesses at least three critical points. Applications to quasilinear boundary...

This paper analyzes the diagnostic of near-multicollinearity in a multiple linear regression from auxiliary centered (with intercept) and noncentered (without intercept) regressions. From these auxiliary regressions, the centered and noncentered variance inflation factors (VIFs) are calculated. An expression is also presented that relates both of them. In addition, this paper analyzes why the VIF is not able to detect the relation between the intercept and the rest of the independent variables...
