Second order evolution equations with nonlocal conditions
(De Gruyter, 2017)In this paper, we shall establish su cient conditions for the existence of solutions for second order semilinear functional evolutions equation with nonlocal conditions in Fréchet spaces. Our approach is based on the ... -
Semiparametric prediction models for variables related with energy production
(SpringerOpen, 2018)In this paper a review of semiparametric models developed throughout the years thanks to an extensive collaboration between the Department of Statistics and Operations Research of the University of Santiago de Compostela ... -
Simulation and Optimization Models of Steady-state Gas Transmission Networks
(Elsevier, 2015)Managing a gas transport network is a complex problem because of the number of possibilities of routing the gas through the pipes. The most important aim in this kind of systems is to fulfill the demand within the pressure ... -
Sistemas de control suplementario da contaminación atmosférica
(Universidade de Santiago de Compostela, 2002)Os sistemas de control suplementario da contaminación atmosférica, baseados en efectuar cambios nas condicións de operación para reduci-las emisións atmosféricas en condicións meteorolóxicas adversas, permiten evita-la ... -
Skim yoghurt with microbial transglutaminase: evaluation of consumer acceptance
(Taylor & Francis, 2019)The decrease in the fat content of yoghurt causes sensory modifications. Microbial transglutaminase (TG) has been proposed as an alternative for reducing the problems caused by the fat reduction. This work deals with the ... -
Soil organic carbon in peninsular Spain: Influence of environmental factors and spatial distribution
(Elsevier, 2020)Soil organic carbon (SOC) stocks and their geographical distribution in peninsular Spain were estimated from a georeferenced database consisting of 12,724 surface samples (0–30 cm) and 3607 subsurface samples (30–50 cm), ... -
Solutions and Green’s function of the first order linear equation with reflection and initial conditions
(Springer International Publishing, 2014)This work is devoted to the study of the existence and sign of Green’s functions for first order linear problems with constant coefficients and initial (one point) conditions. We first prove a result on the existence ... -
Some Results for Integral Inclusions of Volterra Type in Banach Spaces
(SpringerOpen, 2010)We first present several existence results and compactness of solutions set for the following Volterra type integral inclusions of the form: yt ∈ t 0 at − s Ays Fs, ys ds, a.e. t ∈ J, where J 0, b , A is the ... -
Sparse matrix classification on imbalanced datasets using convolutional neural networks
(IEEE, 2019)This paper deals with the class imbalance problem in the context of the automatic selection of the best storage format for a sparse matrix with the aim of maximizing the performance of the sparse matrix vector multiplication ... -
Spatial distribution of invasive species: an extent of occurrence approach
(Springer, 2021)Ecological Risk Assessment faces the challenge of determining the impact of invasive species on biodiversity conservation. Although many statistical methods have emerged in recent years in order to model the evolution of ... -
A Spatially Adaptive Edge-Preserving Denoising Method Based on Fractional-Order Variational PDEs
(IEEE, 2020)Image denoising is a basic problem in image processing. An important task of image denoising is to preserve the significant geometric features such as edges and textures while filtering out noise. So far, this is still a ... -
Spatio-Temporal Dynamic of Malaria Incidence: A Comparison of Two Ecological Zones in Mali
(MDPI, 2020)Malaria transmission largely depends on environmental, climatic, and hydrological conditions. In Mali, malaria epidemiological patterns are nested within three ecological zones. This study aimed at assessing the relationship ... -
Stability of periodic solutions of first-order difference equations lying between lower and upper solutions
(SpringerOpen, 2005)We prove that if there exists α ≤ β, a pair of lower and upper solutions of the first-order discrete periodic problem Δu(n) = f (n,u(n)); n ∈ IN ≡ {0, . . . ,N −1}, u(0) = u(N), with f a continuous N-periodic function ... -
