Using only these observations, some approximate values of the first d-1 derivatives are obtained by a numerical differentiation scheme, and the unknown system parameters are estimated by a ...

Within this context, signal differentiation must be performed causally, that is, using only current and past data and with minimal computational latency. This paper formulates causal differentiation ...

In this paper, numerical simulations of incompressible flows around rotating circular cylinders have been performed. The two-dimensional Navier-Stokes equations are solved by using a Cartesian ...
