New EMI Active Hybrid Active‐Passive Filter With Mixed Voltage‐Current Injection Dedicated to a GaN Based Boost Converter in kW Range

In this article, we propose a novel hybrid EMI filtering technique that directly considers line currents instead of the traditional approach based on their decomposition. This method naturally accounts for propagation characteristics without…

Photothermal radiometry for non-destructive testing and characterization of cultural heritage objects

Photothermal radiometry (PTR) is very attractive for non-destructive testing and characterization of complex art objects and analysis of defects caused by ageing and environmental effects. Our preliminary studies with non-museum paintings were aimed…

Magnetic characterization under PWM and PWM-like excitations

Pulse-Width-Modulation (PWM)-like voltages are typical operating conditions for magnetic cores, but introduce additional complexity in the characterization and loss prediction due to the presence of high-order harmonics, minor hysteresis loops, and…

Experimental Non-Standard Dynamic Hysteresis Loops of NGO Laminations for Model Testing

The standard characterization of electrical steel, made under sinusoidal polarisations, can be insufficient to predict the behavior under real operating conditions of such materials. Most applications suffer from both a consequent harmonic content…

Solving jigsaw puzzles with vision transformers

Puzzle-solving is a problem having applications for instance in archaeology and cultural heritage. Proposed solutions often suffer from a performance loss when the pieces are eroded, a characteristic that is pervasive across various use—cases such…

Stochastic Embeddings: A Probabilistic and Geometric Analysis of Out-of-Distribution Behavior

Deep neural networks perform well in many applications but often fail when exposed to outof-distribution (OoD) inputs. We identify a geometric phenomenon in the embedding space: indistribution (ID) data show higher variance than OoD data under…
