In this paper, a series of results related to the decoupling of the 10m diameter Grantecan’s primary mirror dynamics and its influence on the design of a controller for the mirror are presented. Firstly, an algebraic approach of the decoupling method, together with its general lines are shown. Some modifications of this procedure with respect to the way it was originally proposed with the aim o...

Fusion rules for Wess-Zumino-Witten (WZW) models at fractional level can be defined in two ways, with distinct results. The Verlinde formula yields fusion coefficients that can be negative. These signs cancel in coset fusion rules, however. On the other hand, the fusion coefficients calculated from decoupling of singular vectors are non-negative. They produce incorrect coset fusion rules, howev...

An active decoupling circuit is proposed to suppress on-chip power supply noise in digital VLSI circuits with focus on circuits using low power methodologies like power gating and Dual Vdd. The circuit is designed using 180nm technology and is tested for an ISCAS benchmark for effectiveness in suppressing noise effects as compared to passive decoupling capacitors and previous works. We show a b...

We examine the influence of continuous-wave heteronuclear decoupling on symmetry-based double-quantum homonuclear dipolar recoupling, using experimental measurements, numerical simulations, and average Hamiltonian theory. There are two distinct regimes in which the heteronuclear interference effects are minimized. The first regime utilizes a moderate homonuclear recoupling field and a strong he...

We consider PDE/ODE systems for the simulation of intercellular signaling in multicellular environments. The intracellular processes for each cell described here by ODEs determine the long-time dynamics, but the PDE part dominates the solving effort. Thus, it is not clear if commonly used decoupling methods can outperform a coupling approach. Based on a sensitivity analysis, we present a system...

Control of magnetic levitation systems suffer from coupled physics regardless of control. Feedback control is used to robustly reject disturbances, but is complicated by this coupling. Improved performance is possible by decoupling dynamic disturbance torque, an attractive solution provided by the physics-based control design methodology. Promising approaches include elimination of virtual-zero...
