Environmental Engineering

Enhancement of the Piezocatalytic Response of La‐Doped BiFeO$_3$ Nanoparticles by Defects Synergy

Because of their intrinsic polarization and related properties, ferroelectrics attract significant attention to address energy transformation and environmental protection. Here, by using trivalent‐ion‐lanthanum doping of BiFeO$_3$ nanoparticles (NPs…

Kalman filter for radio source power and direction of arrival estimation

Images are an important source of information for spacecraft navigation. Based on an image and a known attitude, triangulation techniques (intersection or resection) are often used for positioning and navigation. In the resection problem, an…

ML-DOA estimation using a sparse representation of array covariance

Sparse Direction-of-Arrival (DOA) estimators depend on the regularization parameter λ which is often empirically tuned. In this work, conducted under the vectorized covariance matrix model, we are looking for theoretical equivalence between the…

A new closed-loop regulation method dedicated to piezoelectric resonators based isolated DC-DC converter

Magnetic components are widely used in power electronics. Yet, their downscaling with frequency becomes moderate from 100 kHz, which limits the possibility of reducing the volume of the passive components in power converters. Therefore, a major…

Gate-Driving Performance Evaluation Based on a New Figure of Merit

Fast switching within static converters is a key to high-efficiency operation and a source of electromagnetic disturbances that can harm the proper functioning of the converters themselves or the electronic equipment placed in their neighborhood. To…
