El problema inverso de autovalores para matrices de Jacobi no negativas y bisimétricas
(Universidad de Cádiz, 2023)
Text en actes de congrés
Accés obertEn esta comunicación presentamos nuestros recientes resultados en el problema inverso nonegativo para matrices de Jacobi bisimétricas, que consisten en nuevas condiciones necesarias para que una lista dada de números ... -
Graphs attaining the upper bound on the isolation number
(Universidad de Cádiz, 2023)
Text en actes de congrés
Accés obertA set D of vertices of a graph is isolating if the set of vertices not belonging to D or not having a neighbour in D is independent. The isolation number of a graph G, denoted by ¿(G), is the minimum cardinality of an ... -
Shortest coordinated motion for square robots
(Springer, 2023)
Text en actes de congrés
Accés restringit per política de l'editorialWe study the problem of determining minimum-length coordinated motions for two axis-aligned square robots translating in an obstacle-free plane: Given feasible start and goal configurations, find a continuous motion for ... -
Shortest paths in portalgons
(Schloss Dagstuhl - Leibniz-Zentrum für Informatik, 2023)
Text en actes de congrés
Accés obertAny surface that is intrinsically polyhedral can be represented by a collection of simple polygons (fragments), glued along pairs of equally long oriented edges, where each fragment is endowed with the geodesic metric ... -
El secreto mejor guardado: aprendiz de hacker
(Federación Española Sociedades de Profesores de Matemáticas, 2022)
Text en actes de congrés
Accés restringit per política de l'editorialSe presenta una experiencia de aprendizaje de aritmética modular contextualizada en el mundo de la seguridad informática. Todo ello bajo el hilo conductor de una hipotética historia, presentada como un juego de ordenador, ... -
Jet transport-based analysis of absolute reachable domain under a single impulse
(International Astronautical Federation (IAF), 2023)
Text en actes de congrés
Accés restringit per política de l'editorialThis paper proposes a jet transport-based semi-analytical method to precisely compute spacecraft absolute reachable domain under a single impulse, with the consideration of the main orbital perturbations. Firstly, the ... -
Computational methodologies for quasi-periodic orbits and invariant manifold connections in non-autonomous problems
(International Astronautical Federation (IAF), 2023)
Text en actes de congrés
Accés restringit per política de l'editorialSemi-analytical and numerical techniques to systematically analyze and compute natural connections between quasi-periodic orbits associated to non-autonomous systems are considered. Focusing in the non-autonomous Sun-Earth+Moon ... -
Morse cell decomposition and parametrization of surfaces from point clouds
(Publicacions de la Universitat Jaume I, 2022)
Text en actes de congrés
Accés obertAn algorithm for the reconstruction of a surface from a point sample is presented. It proceeds directly from the point-cloud to obtain a cellular decomposition of the surface derived from a Morse function. No intermediate ... -
Quadratic dynamic matrix control for fast cloth manipulation
(Institute of Electrical and Electronics Engineers (IEEE), 2023)
Text en actes de congrés
Accés obertRobotic cloth manipulation is an increasingly relevant area of research, challenging classic control algorithms due to the deformable nature of cloth. While it is possible to apply linear model predictive control to make ... -

Text en actes de congrés
Accés obertIn 1730 Edmund Stone (1695?-1768) published The Method of Fluxions, Both Direct and Inverse, the first part of which is the English translation of L’Hospital’s Analyse des infiniment petits pour l’intelligence des lignes ... -
The study of modern mathematics in the military course of mathematics (1753-1756) of Pedro Padilla
(WTM Verlag für Wissenschaftliche Texte und Medien, 2023)
Text en actes de congrés
Accés obertIn 18th-century Spain, military institutions played an essential role in the teaching of higher mathematics. Toward the end of 1750, an Academy of Mathematics was established at the Royal Guards Barracks in Madrid and was ...
