Micro Nuclear Reactors: Potential Replacements for Diesel Gensets within Micro Energy Grids

open access: yesEnergies, 2020
Resilient operation of medium/large scale off-grid energy systems, which is a key challenge for energy crisis solutions, requires continuous and sustainable energy resources. Conventionally, micro energy grids (MEGs) are adopted to supply electricity and

Optimal threshold padlock systems [PDF]

open access: yesJournal of Computer Security, 2021
In 1968, Liu described the problem of securing documents in a shared secret project. In an example, at least six out of eleven participating scientists need to be present to open the lock securing the secret documents. Shamir proposed a mathematical solution to this physical problem in 1979, by designing an efficient k-out-of- n secret sharing scheme ...

Hyperspectral Anomaly Detection via Discriminative Feature Learning with Multiple-Dictionary Sparse Representation

open access: yesRemote Sensing, 2018
Most hyperspectral anomaly detection methods directly utilize all the original spectra to recognize anomalies. However, the inherent characteristics of high spectral dimension and complex spectral correlation commonly make their detection performance ...

Lie symmetries of Benjamin-Ono equation

open access: yesMathematical Biosciences and Engineering, 2021
Lie Symmetry analysis is often used to exploit the conservative laws of nature and solve or at least reduce the order of differential equation. One dimension internal waves are best described by Benjamin-Ono equation which is a nonlinear partial integro ...

Mean-field optimal control and optimality conditions in the space of probability measures [PDF]

open access: yes, 2020
We derive a framework to compute optimal controls for problems with states in the space of probability measures. Since many optimal control problems constrained by a system of ordinary differential equations (ODE) modelling interacting particles converge

Symmetries of Ricci flows

open access: yesAdvances in Nonlinear Analysis, 2023
In the present work, we find the Lie point symmetries of the Ricci flow on an n-dimensional manifold, and we introduce a method in order to reutilize these symmetries to obtain the Lie point symmetries of particular metrics.

Lie symmetries of Generalized Equal Width wave equations

open access: yesAIMS Mathematics, 2021
Lie symmetry analysis of differential equations proves to be a powerful tool to solve or atleast to reduce the order and non-linearity of the equation. The present article focuses on the solution of Generalized Equal Width wave (GEW) equation using Lie ...

Optimal transport over a linear dynamical system [PDF]

open access: yes, 2017
We consider the problem of steering an initial probability density for the state vector of a linear system to a final one, in finite time, using minimum energy control.

Input-output theory of the unconventional photon blockade [PDF]

open access: yes, 2013
We study the unconventional photon blockade, recently proposed for a coupled-cavity system, in presence of input and output quantum fields. Mixing of the input or output channels still allows strong photon antibunching of the output field, but for ...
