Experimental Hamiltonian identification for controlled two-level systems [PDF]

open access: yes, 2003
We present a strategy to empirically determine the internal and control Hamiltonians for an unknown two-level system (black box) subject to various (piecewise constant) control fields when direct readout by measurement is limited to a single, fixed ...

Maximum Torque Per Ampere Control Strategy of a 5-phase PM Generator in healthy and faulty modes for tidal marine turbine application [PDF]

open access: yes, 2014
The work presented in this paper aims to propose a control strategy being able to extract efficiently energy from a fixed-pitch marine current turbine associated with a 5–phase Permanent Magnet Synchronous Generator (PMSG) in healthy mode and in faulty ...

Optimal Control of Quantum Dissipative Dynamics: Analytic solution for cooling the three level $\Lambda$ system

open access: yes, 2004
We study the problem of optimal control of dissipative quantum dynamics. Although under most circumstances dissipation leads to an increase in entropy (or a decrease in purity) of the system, there is an important class of problems for which dissipation ...

DESIGN AND FIELD TEST OF CORN SEEDING SYSTEM BASE ON FUZZY PID CONTROL METHOD COMBINE WITH PSO [PDF]

open access: yesEngenharia Agrícola
Current corn sowing equipment shows relatively low levels of automation and intelligent response. Issues such as wheel slipping and chain jumping occur in seeders driven by wheels and chains, leading to a decrease in the seeding qualification rate.

Determination and use of feasible operation region in flash distillation control

open access: yesRevista Facultad de Ingeniería Universidad de Antioquia, 2020
Flash distillation is essentially a single stage mass transfer operation. The flash distillation operation is used in this work to highlight the importance of identifying the zone where a system has an appropriate behavior.

Control strategies

open access: yes, 2015
This chapter studies control strategies. Control strategies are listed and explained. It focuses on modeling vaccination in single-strain and multistrain diseases. Different modes of introducing vaccination in models are shown. Imperfect vaccination as a mechanism leading to backward bifurcation and strain replacement is explained.

An improved lion strategy for the lion and man problem

open access: yes, 2017
In this paper, a novel lion strategy for David Gale's lion and man problem is proposed. The devised approach enhances a popular strategy proposed by Sgall, which relies on the computation of a suitable "center".

Effect of Formulation Factors and Oxygen Levels on the Stability of Aqueous Injectable Solution Containing Pemetrexed

open access: yesPharmaceutics, 2020
The aim of this study was to investigate the effects of various parameters at each control strategy in drug product degradation on the stability of pemetrexed in injectable aqueous solution. A forced degradation study confirmed that oxidation is the main

How to Run a Campaign: Optimal Control of SIS and SIR Information Epidemics

open access: yes, 2014
Information spreading in a population can be modeled as an epidemic. Campaigners (e.g. election campaign managers, companies marketing products or movies) are interested in spreading a message by a given deadline, using limited resources.
