LOOP QUANTIZATION OF SHAPE DYNAMICS [PDF]
The Thirteenth Marcel Grossmann Meeting, 2015 Loop Quantum Gravity (LQG) is a promising approach to quantum gravity, in particular because it is based on a rigorous quantization of the kinematics of gravity. A difficult and still open problem in the LQG program is the construction of the physical Hilbert space for pure quantum gravity.

Real-Time Implementation of Robust Loop-Shaping Controller for a VSC HVDC System
Energies, 2021 Voltage source converter (VSC) based HVDC systems are one of the most promising technologies for high voltage bulk power transmission. The reliability and stability of a VSC-based HVDC system greatly depends on the design of a proper controller for the ...

Stability of closed-loop fractional-order systems and definition of damping contours for the design of controllers [PDF]
, 2012 Fractional complex order integrator has been used since 1991 for the design of robust control-systems. In the CRONE control methodology, it permits the parameterization of open loop transfer function which is optimized in a robustness context.

IEEE Open Journal of the Solid-State Circuits Society, 2022 This article presents a hybrid 4th-order delta–sigma modulator (DSM). It combines a continuous-time (CT) loop filter and a discrete-time (DT) passive 2nd-order noise-shaping SAR (NS-SAR). Since the 2nd-order NS-SAR is robust against PVT variation,

Reduction of interchannel interference noise in a two-channel grating-based OCDMA system using a nonlinear optical loop mirror [PDF]
, 2001 We show that a nonlinear optical switch can be used to suppress the interchannel noise generated under multiuser operation within a coherent, direct-sequence optical code-division multiple-access (OCDMA) system.
