ZebraPose: Zebra Detection and Pose Estimation using only Synthetic Data

Autor: Bonetto, Elia, Ahmad, Aamir

Synthetic data is increasingly being used to address the lack of labeled images in uncommon domains for deep learning tasks. A prominent example is 2D pose estimation of animals, particularly wild species like zebras, for which collecting real-world

Networks of Pendula with Diffusive Interactions

Autor: Bonetto, Riccardo, Jardón-Kojakhmetov, Hildeberto, Kuehn, Christian

We study a system of coupled pendula with diffusive interactions, which could depend both on positions and on momenta. The coupling structure is defined by an undirected network, while the dynamic equations are derived from a Hamiltonian; as such, th

On the Eigenvalues of Graphs with Mixed Algebraic Structure

Autor: Bonetto, Riccardo, Kojakhmetov, Hildeberto Jardón

We study some spectral properties of a matrix that is constructed as a combination of a Laplacian and an adjacency matrix of simple graphs. The matrix considered depends on a positive parameter, as such we consider the implications in different regim

Bounds and Phase Transitions for Phonons in Complex Network Structures

Autor: Bonetto, Riccardo

We study a model of networked atoms or molecules oscillating around their equilibrium positions. The model assumes the harmonic approximation of the interactions. We provide bounds for the total number of phonons, and for the specific heat, in terms

Observation of Space-Dependent Rotational Doppler Shifts with a Single Ion Probe

Autor: Barreto, Nicolás Adrián Nuñez, Bonetto, Muriel, Luda, Marcelo Alejandro, Cormick, Cecilia, Schmiegelow, Christian Tomás

We present an experiment investigating the rotational Doppler effect using a single trapped ion excited by two copropagating vortex laser beams. The setup isolates the azimuthal gradients of the fields, eliminating longitudinal and curvature effects.
