Le voyage en train : pour une poétique brachylogique
Babel: Littératures Plurielles, 2018 Le train est un espace où l’on pourra effectuer un voyage intérieur, un voyage en soi-même, et parcourir à nouveau le chemin de sa vie. Car, dans le même temps que le train nous transporte, immobiles, silencieux, d’un espace à un autre, défiant les lois ...

International Journal of Adaptive Control and Signal Processing, EarlyView.This paper proposes two projector‐based Hopfield neural network (HNN) estimators for online, constrained parameter estimation under time‐varying data, additive disturbances, and slowly drifting physical parameters. The first is a constraint‐aware HNN that enforces linear equalities and inequalities (via slack neurons) and continuously tracks the ...

Current Tracking Adaptive Control of Brushless DC Motors
International Journal of Adaptive Control and Signal Processing, EarlyView.In this paper, the current tracking for Brushless Direct Current motors is approached considering uncertainty in the parameters of the motor's model. An adaptive control scheme to compensate electrical parameters uncertainty is proposed without requiring any knowledge of the mechanical parameters.

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

A cold-atom Ramsey clock with a low volume physics package
Scientific ReportsWe demonstrate a Ramsey-type microwave clock interrogating the 6.835 GHz ground-state transition in cold $$^{87}$$ 87 Rb atoms loaded from a grating magneto-optical trap (GMOT) enclosed in an additively manufactured loop-gap resonator microwave cavity. A

Lunar reference systems and their realisations using INPOP ephemerides
Astronomy & AstrophysicsContext. The definition of a reference system plays a crucial role in quantifying geodetic effects and in surface body cartography. Today, the development and specification of the lunar reference system is stimulated by future space missions, some of ...

Hitting Times in Markov Chains with Restart and their Application to Network Centrality [PDF]
, 2017 Motivated by applications in telecommunications, computer scienceand physics, we consider a discrete-time Markov process withrestart. At each step the process eitherwith a positive probability restarts from a given distribution, orwith the complementary ...
