Efficient Endangered Deer Species Monitoring with UAV Aerial Imagery and Deep Learning
Agustín Roca, Gabriel Torre, Juan I. Giribet +4
This paper examines the use of Unmanned Aerial Vehicles (UAVs) and deep learning for detecting endangered deer species in their natural habitats. As traditional identification proc…
Extremal properties and bounds for the generalized algebraic connectivity of graphs in Euclidean spaces
J. Ignacio Alvarez-Hamelin, Juan I. Giribet, Ignacio Mas +1
This article presents new contributions to the study of graph rigidity and its interplay with fundamental graph invariants. Recently, a quantitative measure of graph rigidity in $\…
Enhanced UAV Navigation Systems through Sensor Fusion with Trident Quaternions
Sebastian Incicco, Juan Ignacio Giribet, Leonardo Colombo
This paper presents an integrated navigation algorithm based on trident quaternions, an extension of dual quaternions. The proposed methodology provides an efficient approach for a…
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…
Adaptive Multirobot Virtual Structure Control using Dual Quaternions
Juan I. Giribet, Alejandro S. Ghersin, Ignacio Mas +3
This paper presents a control strategy based on dual quaternions for the coordinated formation flying of small UAV groups. A virtual structure is employed to define the desired for…
Prototyping of a multirotor UAV for precision landing under rotor failures
Alvaro J. Gaona, Claudio D. Pose, Juan I. Giribet +1
This work presents a prototype of a multirotor aerial vehicle capable of precision landing, even under the effects of rotor failures. The manuscript presents the fault-tolerant tec…
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…
Learning-Based Fault-Tolerant Control for an Hexarotor with Model Uncertainty
Leonardo J. Colombo, Manuela Gamonal Fernandez, Juan I. Giribet
In this paper we present a learning-based tracking controller based on Gaussian processes (GP) for a fault-tolerant hexarotor in a recovery maneuver. In particular, to estimate cer…
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…
Spectral enclosures for a class of block operator matrices
Juan Giribet, Matthias Langer, Francisco Martínez Pería +2
We prove new spectral enclosures for the non-real spectrum of a class of block operator matrices with self-adjoint operators and on the diagonal and operators $B…
