Adaptive fine-tuning of nonlinear control systems with application to the urban traffic control strategy TUC

Practical large-scale nonlinear control systems require an intensive and time-consuming effort for the fine-tuning of their control parameters in order to achieve a satisfactory performance. In most cases, the fine-tuning process may take years and is perf ...

Position-flexible elaboration of halogenated heterocycles: Metalated species as key intermediates for synthesis

Halogens, in particular fluorine atoms, are favorite tools to fine-tune the chemical and biological properties of pharmaceutical or agricultural development products. At the same time, such an electronegative substituent can effectively assist the site-sel ...

A drift-kinetic Semi-Lagrangian 4D code for ion turbulence simulation

Olivier Sauter, Laurent Villard

A new code is presented here, named Gyrokinetic SEmi-LAgragian (GYSELA) code, which solves 4D drift-kinetic equations for ion temperature gradient driven turbulence in a cylinder (r, theta, z). The code validation is performed with the slab ITG mode that o ...

Measurement of the running of the electromagnetic coupling at large momentum-transfer at LEP

Qian Wang, Aurelio Bay, Horst Vogel, Eduardo Sanchez, Zhirui Xu, Werner Lustermann, Liang Sun, Jian Zhao, Ji Hyun Kim, Zheng Wang, Matthias Weber, Xiao Wang

The evolution of the electromagnetic coupling, α, in the momentum-transfer range 1800 GeV2 < -Q2 < 21600 GeV2 is studied with about 40 000 Bhabha-scattering events collected with the L3 detector at LEP at centre-of-mass energies √s = 189-209 GeV. The runni ...
