A Distributed SPI-Based Architecture for Reliable Force Estimation in Wheeled Humanoid Robots

H. Meneses, César A. Arias, Luis E. Gillen Brenes, Antonio José Lozano Guerrero et autres

This paper proposes an implementation of the Serial Peripheral Interface (SPI) protocol to manage data information coming from four slave STM32F407Discovery microcontrollers that process data from its own force-torque sensor located in each corner of the mobile platform of a humanoid robot. …

Dark matter axion detection method using neural networks for ultralow signal-to-noise ratio

Alejandro Díaz‐Morcillo, José Gadea-Rodríguez, Benito Gimeno Martínez, Antonio José Lozano Guerrero et autres

We present the first analysis of dark matter axion detection applying neural networks for the improvement of sensitivity. The main sources of thermal noise from a typical readout chain are simulated, constituted by resonant and amplifier noises. With this purpose, an advanced …

Multiple-cavities interferometric analysis for dark matter axions directional-sensitive search based on signal cross-correlation processing

José Reina‐Valero, Alejandro Díaz‐Morcillo, B. Gimeno, Antonio José Lozano Guerrero et autres

Current axion detection limits neglect the relevance of the relative velocity between the axion field and the detectors. However, this aspect can lead to a daily modulation of the detected axion signal. In this work, we calculate the cross-correlation of various signals …

Methods and restrictions to increase the volume of resonant rectangular-section haloscopes for detecting dark matter axions

J. M. García-Barceló, Alejandro Álvarez Melcón, Alejandro Díaz‐Morcillo, B. Gimeno et autres

Abstract Haloscopes are resonant cavities that serve as detectors of dark matter axions when they are immersed in a strong static magnetic field. In order to increase the volume and improve space compatibility with dipole or solenoid magnets for axion searches, various …

Dielectric Characterization of Fabric Aggregates around the 2.45 GHz ISM Band under Various Humidity, Density, and Temperature Conditions

Rafael Pérez-Campos, Juan Monzó‐Cabrera, José Fayos-Fernández, Alejandro Díaz‐Morcillo et autres

Fabric permittivity is critical for the manufacturing of wearable sensors and antennas as well as predicting how fabrics interact with electromagnetic fields. Engineers should also understand how permittivity changes under different temperatures, densities, and moisture content values, or when several fabrics are …
