A non markovian retrial queueing system
(Elsevier, 2023)This paper studies a discrete-time queueing system in which a customer who enters in the system with a server occupied may choose to go to the retrial group or to begin its service displacing to the retrial group the ... -
Approaching the square of opposition in terms of the f-indexes of inclusion and contradiction
(Elsevier, 2023-10-31)We continue our research line on the analysis of the properties of the f-indexes of inclusion and contradiction; in this paper, specifically, we show that both notions can be related by means of the, conveniently reformulated, ... -
Connecting ideals in evolution algebras with hereditary subsets of its associated graph
(2023)In this article, we introduce a relation including ideals of an evo-lution algebra and hereditary subsets of vertices of its associated graph andestablish some properties among them. This relation allows us to determinemaximal ... -
Distributionally robust stochastic programs with side information based on trimmings
(Springer, 2021-11)We consider stochastic programs conditional on some covariate information, where the only knowledge of the possible relationship between the uncertain parameters and the covariates is reduced to a finite data sample of ... -
Fuzzy Closure Structures as Formal Concepts II
(Elsevier, 2023-09-24)This paper is the natural extension of Fuzzy Closure Structures as Formal Concepts. In this paper we take into consideration the concept of closure system which is not dealt with in the previous one. Hence, a connection must ... -
Mean curvature of spacelike submanifolds in a Brinkmann spacetime
(2021)Several geometric properties of complete spacelike submanifolds, with codimension at least two, in a Brinkmann spacetime are shown from natural assumptions involving the mean curvature vector field $\mcv$ of the spacelike ... -
Sojourn Times in a Queueing System with Breakdowns and General Retrial Times.
(MDPI, 2021-11-12)This paper centers on a discrete-time retrial queue where the server experiences breakdowns and repairs when arriving customers may opt to follow a discipline of a last-come, first-served (LCFS)-type or to join the orbit. ... -
Statistical structures arising in null submanifolds
(Elsevier, 2022-12-22)We show a link between affine differential geometry and null submanifolds in a semi-Riemannian manifold via statistical structures. Once a rigging for a null submanifold is fixed, we can construct a semi-Riemannian metric ... -
Using the Chu Construction for generalizing formal concept analysis
(2015-11-23)El objetivo de este artículo es mostrar la conexión entre generalizaciones de Análisis de Conceptos Formales y la construcción de Chu sobre la categoría ChuCors de contextos formales y correspondencias de Chu. Todas las ...
