Subframework-based Bearing Rigidity Maintenance Control in Multirobot Networks
J. Francisco Presenza, Ignacio Mas, J. Ignacio Alvarez-Hamelin +1
This work presents a novel approach for \textit{bearing rigidity} analysis and control in multi-robot networks with sensing constraints and dynamic topology. By decomposing the sys…
Synchronization between media followers and political supporters during an election process: towards a real time study
Rémi Perrier, Laura Hernández, J. Ignacio Alvarez-Hamelin +1
We present an analysis of the dynamics of discussions in Twitter (before it became X) among supporters of various candidates in the 2022 French presidential election, and followers…
A New Upper Bound for the d-dimensional Algebraic Connectivity of Arbitrary Graphs
Juan F. Presenza, Ignacio Mas, Juan I. Giribet +1
In this paper we show that the -dimensional algebraic connectivity of an arbitrary graph is bounded above by its -dimensional algebraic connectivity, i.e., $a_d(G) \leq a…
Who talks about what? Comparing the information treatment in traditional media with online discussions
Hendrik Schawe, Mariano Gastón Beiró, J. Ignacio Alvarez-Hamelin +2
We study the dynamics of interactions between a traditional medium, the New York Times journal, and its followers in Twitter, using a massive dataset. It consists of the metadata o…
Designing weighted and multiplex networks for deep learning user geolocation in Twitter
Federico M. Funes, José Ignacio Alvarez-Hamelin, Mariano G. Beiró
Predicting the geographical location of users of social media like Twitter has found several applications in health surveillance, emergency monitoring, content personalization, and…
Subframework-Based Rigidity Control in Multirobot Networks
Juan F. Presenza, J. Ignacio Alvarez-Hamelin, Ignacio Mas +1
This paper presents an alternative approach to the study of distance rigidity in networks of mobile agents, based on a subframework scheme. The advantage of the proposed strategy l…
