Effect of current intensity and polarity on the electrical performances of slip ring contacts

Corentin Ferreira, Manon Isard, Sophie Noël, Aurore Brézard-Oudot, Frédéric Houzé, Philippe Teste

In this investigation, the effect of current has been studied on sliding electrical contacts between bulk gold-alloy wires and gold-alloy plated rings. Two parameters have been examined: current intensity, and direction of current. For this purpose, a model slip ring has been used which includes 4…

Direction-of-Arrival Estimation of Coherent Sources with Leaky-Wave Antennas using Spatially Filtered Interpolation

Rida Maydani, Yide Wang, Julien Sarrazin

With their frequency-beam scanning behavior, leaky-wave antennas (LWAs) are promising solutions to develop accurate and cost-effective direction-of-arrival (DoA) estimation systems. However, DoA estimators such as MUSIC face challenges with coherent sources due to the non-Vandermonde LWA steering…

A Hodgkin-Huxley Interpretation of Power Amplifiers Memory Effects in Stochastic Computing

Siqi Wang, Yueyuan Gao, Shipra Shipra, A. Benlarbi-Delai

This paper reports an interpretation of the memory effects of radiofrequency (RF) power amplifiers (PA) from the perspective of stochastic neural networks. The nonlinearity of RF PA is found biomimicking and can enhance neuromorphic computing capacities of a joint communication and computation (J2C…
