Multi-machine analysis of termination scenarios, providing the specifications for controlled shutdown of ITER discharges

Olivier Sauter, Sun Hee Kim, Francesca Maria Poli, Anna Teplukhina

The task is to show that the specific ITER design features allow a stable well-controlled termination. This is a joint effort in control, exception handling development and physics modelling. Relevant for ITER is to maintain vertical, radial position, and ...

Diffusion social learning over weakly-connected graphs

Ali H. Sayed, Bicheng Ying

In this paper, we study diffusion social learning over weakly-connected graphs. We show that the asymmetric flow of information hinders the learning abilities of certain agents regardless of their local observations. Under some circumstances that we clarif ...

Distributed model predictive control of energy systems in microgrids

François Maréchal, Paul Michael Stadler, Araz Ashouri

This paper presents a flexible and modular control scheme based on distributed model predictive control (DMPC) to achieve optimal operation of decentralized energy systems in smart grids. The proposed approach is used to coordinate multiple distributed ene ...

Enantioselective Total Synthesis of (−)-Terengganensine A

Qian Wang, Jieping Zhu, Cyril Piemontesi

A seven-step enantioselective total synthesis of (-)-terengganensine A, a complex heptacyclic monoterpene indole alkaloid, was accomplished. Key steps included: a) Noyori's catalytic enantioselective transfer hydrogenation of the iminium salt to set up the ...

Mission Design and GNC for In-Orbit Demonstration of Active Debris Removal Technologies with CubeSats

Volker Gass, Muriel Richard, Camille Sébastien Pirat, Federico Belloni, Reto Wiesendanger, Christophe Dominique Paccolat

Within the frame of the ESA's General Support Technology Programme, two In-Orbit Demonstration (IOD) missions using CubeSat technologies were studied. These IODs aim at alleviating the technical risk inherent to new technologies required for Active Debris ...

Development of a precision machine to perform and study orthogonal micro-cutting

Kossi Agbeviade, Jacques Giovanola, Jennifer Gasparoux

This article presents a laboratory machine designed to perform orthogonal micro-cutting experiments. The machine allows an accurate control of the various cutting parameters and a direct comparison of micro-and macrocutting tool-material data bases. Resear ...

Time-Optimal Path-Following Operation in the Presence of Uncertainty

Dominique Bonvin, Timm Faulwasser, Alejandro Gabriel Marchetti, Predrag Milosavljevic

Path-following tasks, which refer to dynamic motion planning along pre-specified geometric references, are frequently encountered in applications such as milling, robot-supported measurements, and trajectory planning for autonomous vehicles. Different conv ...

Demonstration of efficient spin injection in a CW VECSEL at RT and dynamic control of its polarization state

Alexei Sirbu

We report the first efficient spin injection in a CW optically pumped VECSEL, obtained with phase anisotropy dynamic control. A threshold reduction of 1.5 % and an ellipticity of 75% are obtained at RT. Theoretical and experimental investigation of the pol ...

Performance limits of single-agent and multi-agent sub-gradient stochastic learning

Ali H. Sayed, Bicheng Ying

This work examines the performance of stochastic sub-gradient learning strategies, for both cases of stand-alone and networked agents, under weaker conditions than usually considered in the literature. It is shown that these conditions are automatically sa ...
