IEEE Access, 2020 The existing distributed operation schemes for microgrids lack the ability to determine the power selling to the grid during normal operation mode and are unable to provide service reliability to critical loads, during islanded operation mode.

Enhancing quantum entanglement for continuous variables by a coherent superposition of photon subtraction and addition [PDF]
, 2011 We investigate how the entanglement properties of a two-mode state can be improved by performing a coherent superposition operation of photon subtraction and addition, proposed by Lee and Nha [Phys. Rev. A 82, 053812 (2010)], on each mode.

On the Selection of Optimal Index Configuration in OO Databases [PDF]
, 1994 An operation in object-oriented databases gives rise to the processing of a path. Several database operations may result into the same path. The authors address the problem of optimal index configuration for a single path. As it is shown an optimal index

Unconstrained receding-horizon control of nonlinear systems [PDF]
, 2001 It is well known that unconstrained infinite-horizon optimal control may be used to construct a stabilizing controller for a nonlinear system. We show that similar stabilization results may be achieved using unconstrained finite horizon optimal control ...

Optimal potentials for Schrödinger operators
Journal de l’École polytechnique — Mathématiques, 2014 We consider the Schrödinger operator -Δ+V(x) on H 0 1 (Ω), where Ω is a given domain of ℝ d . Our goal is to study some optimization problems where an optimal potential V≥0 has to be determined in some suitable admissible classes and for some suitable optimization criteria, like the energy or the Dirichlet eigenvalues.

Review of Uncertainty Modeling for Optimal Operation of Integrated Energy System
Frontiers in Energy Research, 2022 The operation of the integrated energy system will be affected by uncertainties, leading to sub-optimal design decisions. Accurate and effective modeling of these uncertainties is essential to ensure the optimal integration of renewable energy in the ...
