System Theory - A Modern Approach 1

The theory of dynamic systems is addressed in this book in accordance with the "modern" approach, heir to algebraic analysis, which was implemented since the last decade of the 20th century. After a reminder of the evolution of the representation of…

Methods to Measure the Electrical Resistances of a Gas Diffusion Layer Under Mechanical Compression

In a proton exchange membrane fuel cell (FC), the gas diffusion layer (GDL) is identified as the component that is most affected by mechanical compression. In this article, a particular focus is provided on the methods to measure the three main…

Analysis of DC-Link Low-Frequency Current Harmonics in Multi-Source Multi-Three-Phase Electric Drives

In a multi-source permanent magnet synchronous motor (PMSM) drive, three distinct winding structures can be implemented: multi-sector, multi-three-phase, and highly coupled. However, due to variations in the magnetic coupling between windings, their…

Adequate structuring of the latent space for easy classification and out-of-distribution detection

Out-of-distribution (OoD) detection is the corner-stone of reliability in machine learning (ML) applications. Since OoD samples follow a different statistic than those on which the model is trained, the corresponding model decision is likely to be…

A Contrario Paradigm for Yolo-Based Infrared Small Target Detection

Detecting small to tiny targets in infrared images is a challenging task in computer vision, especially when it comes to differentiating these targets from noisy or textured backgrounds. Traditional object detection methods such as YOLO struggle to…

Structure at infinity and defect of transfer matrices with time-varying coefficients, with application to exact model-matching

We study the structure at infinity of transfer matrices with time-varying coefficients. Such transfer matrices have their entries in a skew field $% \mathbf{F}$ of rational fractions, i.e. of quotients of skew polynomials. Any skew rational fraction…
