Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Conference Paper Description
In this paper, the generalized synchronization of chaotic systems is formulated as a nonlinear optimal control problem where constraints on control variables are also considered. The nonlinear constrained optimal control problem is solved by a symplectic pseudospectral method. Via this method, chaotic synchronization problems under the following three different conditions are studied: (1) the master and the slave systems are identical but with different initial values; (2) the master and the slave systems are different but dimensionalities of two systems are same; (3) the master and the slave systems are of different dimensionalities. Numerical simulations demonstrate the effectiveness of the symplectic pseudospectral optimal control method. Master and slave systems are synchronized rapidly and constraints on control are strictly satisfied. By enlarging the weight parameters on the generalized error in the cost functional, it results in a more rapid synchronization.
