Advantage of Increasing the Number of Airgap Surfaces in Synchronous Linear Actuators

This paper presents an realistic comparison of several electromagnetic architectures forhigh force density actuators. Firstly a simple classification of synchronous actuators is presented. Four equivalent architectures are chosen and modelized by…

Soft lithographic techniques for guidance of hippocampal neurons on micro-electrode arrays

In this work, different micropatterning methods were tested for use in patterning of primary culture neural cells. Etching of Teflon covered glass substrates was used to make shallow neural guides defined by hydrophobic/hydrophilic regions. A three…

Conception et étude d'un actionneur linéaire synchrone à aimants permanents et multi-plaques

Dans de nombreuses applications, il est nécessaire de disposer d'un actionneur à très forte densité d'effort en entraînement direct. Les solutions mettant en oeuvre des dispositifs mécaniques intermédiaires de transformation (réducteur, vis écrou)…

Application of model-based spectral analysis to wind-profiler radar observations

A classical way to reduce a radar's data is to compute the spectrum using FFT and then to identify the different peak contributions. But in case an overlapping between the different echoes (atmospheric echo, clutter, hydrometeor echo. . . ) exists,…
