Effects of disc-shaped piezoelectric size reduction on resonant inductorless DC-DC converter

This paper studies the impact of disc-shaped piezoelectric resonator dimensions on a non-isolated inductorless piezoelectric DC-DC converter. An analytical model, linking geometrical parameters to output power and efficiency is introduced. This…

Detecting alterations in historical violins with optical monitoring

Some historical musical instruments are still played today, and are prone to be affected by mechanical wear of superficial varnishes in direct contact with the musicians. In a previous work, an ad-hoc monitoring plan for historical violins, that…

Study of the Impedance of the Bypassing Network of a Switching Cell -Influence of the Positioning of the Decoupling Capacitors

Mechanisms responsible for ringing and oscillations in power converters at transistors turn-offs are, first, studied using small signal modelling. It is explained why a 50 % derating must be applied to high-speed transistors. Experimental…

Augmenting Deep Learning Performance in an Evidential Multiple Classifier System

The main objective of this work is to study the applicability of ensemble methods in the context of deep learning with limited amounts of labeled data. We exploit an ensemble of neural networks derived using Monte Carlo dropout, along with an…

Study of Low Frequency Magnetic Shielding of a Thin Al/Steel/Al Composite in Various Applications

A composite constituted of a steel sheet taken in a sandwich between two aluminum (Al) sheets is produced by cold roll bonding. A good adherence between Al and steel sheets, ensuring a good mechanical resistance, is obtained with a specific process…
