Controlling of pandemic COVID-19 using optimal control theory [PDF]

open access: yesResults in Physics, 2021
In 2019, a new infectious disease called pandemic COVID-19 began to spread from Wuhan, China. In spite of the efforts to stop the disease, being out of the control of the governments it spread rapidly all over the world.

Inferring intrinsic neural timescales using optimal control theory [PDF]

open access: yesNature Communications
The temporal evolution of whole-brain activity is contingent upon complex interactions within and between brain regions that are mediated by neurobiology and connectivity, respectively.

Optimal control theory of harmonic generation [PDF]

open access: yesPhysical Review A, 2012
Coherent control of harmonic generation was studied theoretically. A specific harmonic order was targeted. An optimal control theory was employed to find the driving field where restrictions were imposed on the frequency band.

An optimal control theory approach to non-pharmaceutical interventions [PDF]

open access: yesBMC Infectious Diseases, 2010
Background Non-pharmaceutical interventions (NPI) are the first line of defense against pandemic influenza. These interventions dampen virus spread by reducing contact between infected and susceptible persons.

Combining optimal control theory and molecular dynamics for protein folding. [PDF]

open access: yesPLoS ONE, 2012
A new method to develop low-energy folding routes for proteins is presented. The novel aspect of the proposed approach is the synergistic use of optimal control theory with Molecular Dynamics (MD).

Modifications of Flower Pollination, Teacher-Learner and Firefly Algorithms for Solving Multiextremal Optimization Problems

open access: yesAlgorithms, 2022
The article offers a possible treatment for the numerical research of tasks which require searching for an absolute optimum. This approach is established by employing both globalized nature-inspired methods as well as local descent methods for ...

Quantum optimal control theory [PDF]

open access: yesJournal of Physics B: Atomic, Molecular and Optical Physics, 2007
The control of quantum dynamics via specially tailored laser pulses is a long-standing goal in physics and chemistry. Partly, this dream has come true, as sophisticated pulse shaping experiments allow to coherently control product ratios of chemical reactions. The theoretical design of the laser pulse to transfer an initial state to a given final state

Hover flight control of helicopter using optimal control theory [PDF]

open access: yesINCAS Bulletin, 2015
This paper represents the optimal control theory and its application to the full scale helicopters. Generally the control of a helicopter is a hard task, because its system is very nonlinear, coupled and sensitive to the control inputs and external ...
