2D GPU-based HySEA model for tsunami simulation. Some practical examples.
(2014-07-11)A two-waves TVD-WAF type scheme for solving 2D shallow-water equation is considered together with a first and second order HLL scheme. Comparison among the different schemes will be performed to check the performance for ... -
A Discrete-Time retrial queueing system with service upgrade
(2015-06-10)We study the Markov chain underlying the considered queueing system obtaining the gen- erating function of the number of customers in the orbit and in the system as well as the stationary distribution of the time that a ... -
A generalized framework to consider positive and negative attributes in formal concept analysis
(2014-10-23)In Formal Concept Analysis the classical formal context is analized taking into account only the positive information, i.e. the presence of a property in an object. Nevertheless, the no presence of a property in an object ... -
A logic-based approach to compute a direct basis from implications
(2014-09-19)Formal Concept Analysis is an emergent area in the topic of data analysis based on lattice theory. In this framework, a context is defined as the relation between a set of objects and a set of attributes and from here it ... -
CAISL: Simplification Logic for Conditional Attribute Implications
(2016-07-25)In this work, we present a sound and complete axiomatic system for conditional attribute implications (CAIs) in Triadic Concept Analysis (TCA). Our approach is strongly based on the Simplification paradigm which offers a ... -
Cluster Analysis of Finger-to-nose Test for Spinocerebellar Ataxia Assessment
(2015-06-18)El test Finger-to-nose test (FNT) es una evaluación neurológica para estudiar la coordinación. Se presenta una metodología de análisis de datos de FNT, que permite evaluar la evolución del estado de enfermos de Ataxia ... -
Computer Algebra-based RBES personalized menu generator
(2015-07-27)People have many constraints concerning the food they eat. These constraints can be based on religious believes, be due to food allergies or to illnesses, or can be derived just from personal preferences. Therefore, ... -
Conjugate Points along lightlike geodesics of Lorentzian manifolds
(2013-07-29)En esta charla se muestran algunas propiedades que relacionan la distribución de los puntos conjugados en las geodésicas luz con propiedades globales tanto geométricas como topológicas de la variedad. Los resultados expuestos ... -
Estimating radial railway network improvement with a CAS
(2013-09-17)The Spanish railway network is very complex, with two different track gauges: the broad classic Iberian track gauge and the so called international gauge, the latter used in the extensive high speed network. All new lines ... -
Extending FuzAtAnalyzer to approach the management of classical negation
(2015-09-16)FuzAtAnalyzer was conceived as a Java framework which goes beyond of classical tools in formal concept analysis. Specifically, it successfully incorporated the management of uncertainty by means of methods and tools from ... -
Fuzzy Adjunctions revisited
(2016-05-30)En este trabajo se intenta obtener la noción de adjunción más débil entre estructuras difusas. Este trabajo continúa la línea de investigación en el estudio y construcción d adjunciones que han realizado los autores en ... -
Geometric integration methods of high order for gradient systems
(2014-07-18)We propose the higher order extension of numerical methods that preserve the energy-diminishing feature of a system with Lyapunov function. -
Geometric Numerical Integration of Gradient Systems
(2013-11-12)We construct and analyse numerical methods that preserve a Lyapunov function of a dynamical system. -
Graduaciones y álgebras de Lie simples
(2014-09-22)Esta conferencia da una panorámica sobre cómo el concepto de graduación ha ayudado a la comprensión de la estructura en el caso de las álgebras de Lie simples, a la vez que expone el estado actual de la clasificación de ... -
Hopfield networks: from optimization to adaptive control
(2015-07-08)This paper proposes an adaptative control algorithm, which is designed by adding a parametric identification method to a non-linear controller. The identification module is built upon the Hopfield neural network, resulting in ... -
Making more flexible ATISMART+ model for traffic simulations using a CAS
(2015-07-28)Traffic simulations usually require the search of a path to join two different points. Dijkstra’s algorithm [1] is one of the most commonly used for this task due to its easiness and quickness. In [2, 3] we developed an ... -
Metadomotic Optimization Using Genetic Algorithms
(2014-07-17)New technologies applied in domotic allow us to extract plenty of data about the usual behavior of occupants in any installation. Discipline that works with these data for the pursuit of new knowledge is called Metadomotic. To ... -
Numerical Implementation of Gradient Algorithms
(Springer, 2013)A numerical method for computational implementation of gradient dynamical systems is presented. The method is based upon the development of geometric integration numerical methods, which aim at preserving the dynamical ... -
Numerical Integration of Lattice Systems with a Lyapunov Function
(2014-06-24)In this contribution we implement and assess numerical methods for gradient systems, i.e. dynamical systems that possess a Lyapunov function, and consequently are stable. In particular, we claim that discrete gradient ... -
On the notion of fuzzy adjunctions between fuzzy orders
(2015-10-21)Las adjunciones (también denominadas conexiones de Galois isótonas) entre dos estructuras matemáticas proporcionan una manera de conectar ambas teorías que permite compartir las ventajas de ambas. Hay varios resultados en ...
