Fuel cell diagnosis method based on multifractal analysis of stack voltage signal

Measuring local singularities on voltage signal transmits valuable information about the evolving dynamics of non-stationary and nonlinear processes in fuel cell systems. This paper deals with wavelet transform combined with multifractal formalism…

Rethinking climate engineering categorization in the context of climate change mitigation and adaptation

The portfolio of approaches to respond to the challenges posed by anthropogenic climate change has broadened beyond mitigation and adaptation with the recent discussion of potential climate engineering options. How to define and categorize climate…

Broadband magnetic losses in Fe-Si and Fe-Co laminations

We discuss comprehensive broadband (DC – 10 kHz) investigations on magnetic losses in Fe-(3 wt%)Si and Fe-Co laminations. In this range of frequencies, the prediction of loss is not easy, because skin effect can be quite important. The theoretical…

Développement et études de performances de nouveaux détecteurs/filtres rang faible dans des configurations RADAR multidimensionnelles

Most of statistical signal processing algorithms, are based on the use of signal covariance matrix. In practical cases this matrix is unknown and is estimated from samples. The adaptive versions of the algorithms can then be applied, replacing the…

Functional Analysis

ON SEMI-BARRELLED SPACES

The aim of this paper is to clarify the properties of semi-barrelled spaces (also called countably quasi-barrelled spaces in the literature). These spaces were studied by several authors, in particular in the classical book of N. Bourbaki "Espaces…
