Quasi-closed elements in fuzzy posets
(ELSEVIER, 2022-04)We generalize the notion of quasi-closed element to fuzzy posets in two stages: First, in the crisp style in which each element in a given universe either is quasi-closed or not. Second, in the graded style by defining ... -
Representations of relative Cohn path algebras.
(Elsevier, 2020-01-07)We study relative Cohn path algebras, also known as Leavitt-Cohn path algebras, and we realize them as partial skew group rings. To do this we prove uniqueness theorems for relative Cohn path algebras. Furthermore, given ... -
Rigidity results for complete spacelike submanifolds in plane fronted waves
(Springer, 2022-09-08)New rigidity results for complete non-compact spacelike submanifolds of arbitrary codimension in plane fronted waves are obtained. Under appropriate assumptions, we prove that a complete spacelike submanifold in these ... -
Scalable method for administration of resource technologies under stochastic procedures
(Elsevier, 2022-11-09)During the development of the S3Unica project (Smart Specialisation University Campus) and its application in the ASSET project (Advanced Systems Studies for Energy Transition), both within the European Commission, the ... -
Simplification logic for the management of unknown information
(Elsevier, 2023)This paper aims to contribute to the extension of classical Formal Concept Analysis (FCA), allowing the management of unknown information. In a preliminary paper, we define a new kind of attribute implications to represent ... -
Smart Sensorization Using Propositional Dynamic Logic
(IOAP-MPDI, 2022-05-20)The current high energy prices pose a serious challenge, especially in the domestic economy. In this respect, one of the main problems is obtaining domestic hot water. For this reason, this article develops a heating system ... -
SMIS: A Stepwise Multiple Integration Solver Using a CAS.
(MDPI, 2021-11-11)Multiple Integration is a very important topic in different applications in Engineering and other Sciences. Using numerical software to get an approximation to the solution is a normal procedure. Another approach is working ... -
SODES: Solving ordinary differential equations step by step
(Elsevier, 2023)In this paper, we introduce SODES (Stepwise Ordinary Differential Equations Solver) a new solver for Ordinary Differential Equations (ODE). SODES can optionally provide the solution displaying all the steps needed to obtain ... -
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 ... -
The commutative core of a Leavitt path algebra.
(Elsevier, 2018-06-30)For any unital commutative ring R and for any graph E, we identify the commutative core of the Leavitt path algebra of E with coefficients in R, which is a maximal commutative subalgebra of the Leavitt path algebra. ... -
The cycline subalgebra of a Kumjian-Pask algebra.
(American Mathematical Society, 2016-11-21)Let $\Lambda$ be a row-finite higher-rank graph with no sources. We identify a maximal commutative subalgebra $\mathcal{M}$ inside the Kumjian-Pask algebra ${\rm KP}_R(\Lambda)$. We also prove a generalized Cuntz-Krieger ... -
The f -index of inclusion as optimal adjoint pair for fuzzy modus ponens
(Elsevier, 2023)We continue studying the properties of the f -index of inclusion and show that, given a fixed pair of fuzzy sets, their f -index of inclusion can be linked to a fuzzy conjunction which is part of an adjoint pair. We also ... -
The reduction theorem for algebras of one-sided subshifts over arbitrary alphabets.
(Springer, 2024-02-21)Let R be a commutative unital ring, X a subshift, and A_R(X) the corresponding unital subshift algebra. We establish the reduction theorem for A_R(X). As a consequence, we obtain a Cuntz-Krieger uniqueness theorem for ... -
Too Many Males or Too Many Females? Classroom Sex Ratio, Life History Strategies and Risk-Taking Behaviors
(Springer, 2022-06-01)Prior research finds that sex ratio, defined as the proportion of males and females in a given context, is related to engagement in risk-taking behaviors. However, most research operationalizes sex ratio at a local context ... -
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 ... -
Vertically averaged and moment equations: new derivation, efficient numerical solution and comparison with other physical approximations for modeling non-hydrostatic free surface flows
(Elsevier, 2024-02-27)Efficient modeling of flow physics is a prerequisite for a reliable computation of free-surface environmental flows. Non-hydrostatic flows are often present in shallow water environments, making the task challenging. In ... -
Well Generatedness and Adjoints for Homotopy Categories of N-complexes
(Springer, 2023)Let R be a ring and N ≥ 2. First, we prove that any deconstructible class of modules F over R induces two coreflective subcategories of the homotopy category KN (Mod−R) of (unbounded) N -complexes of right R-modules: the ...
