Magnetic behaviour of Polyaniline/BaFe12O19 composites synthesised by two different pathways

Polyaniline/BaFe12O19 composites synthesised by two different polymerization pathways: chemical polymerization and solid-state polymerization, were studied. The influence was explored by the type of polymerization synthesis on the microstructure and…

CFAR property and robustness of the lowrank adaptive normalized matched filters detectors in low rank compound gaussian context

In the context of an heterogeneous disturbance with a Low Rank (LR) structure (referred to as clutter), one may use the LR approximation for detection process. Indeed, in such context, adaptive LR schemes have been shown to require less secondary…

Damping model-free analysis of a stochastic multi-scale frame element for earthquake engineering applications

The viscous damping forces commonly added in earthquake engineering applications lack a sound physical justification. Consequently, whether or not they accurately represent what they are added for is uncertain. In this paper, this latter source of…

Analytical Approach for Mechanical Resonance Frequencies of High-Speed Machines

This paper presents an analytical approach for the determination of the mechanical eigenfrequencies of an electrical machine stator. This model is based on the calculation and the minimization of Rayleigh's quotient. It uses an energetic approach…

Force magnétique. Une autre manière de voir les choses.

Les notions de force magnétique et de couple électromagnétique sont deux notions difficiles d'accès à un grand nombre d'étudiants. La force de Laplace est, elle, bien maîtrisée. Cependant peu de dispositifs de conversion d'énergie utilisent ce…

Exploiting persymmetry for low-rank Space Time Adaptive Processing

Reducing the number of secondary data used to estimate the Covariance Matrix (CM) for Space Time Adaptive Processing (STAP) techniques is still an active research topic. Within this framework, the Low-Rank (LR) structure of the clutter is well-known…

Tangible needle, digital haystack: tangible interfaces for reusing media content organized by similarity

This paper presents the design process of a desk-set tangible user interface for the navigation and manipulation of media content organized by content-based similarity with off-the-shelf/flea market devices. For intra-media navigation, a refurbished…
