Dynamical decoupling is a key method to mitigate errors in quantum mechanical system, and we studied it series of papers dealing, particular, with the problems arising from unbounded Hamiltonians. The standard bangbang model dynamical decoupling, which also used those papers, requires operations infinite amplitude, is, strictly speaking, unrealistic physical point view. In this paper, look at f...

Abstract. A class of implicit methods is introduced for Ito stochastic differential equations with Poisson-driven jumps. A convergence proof shows that these implicit methods share the same strong finite-time convergence rate as the explicit Euler–Maruyama scheme. A mean-square linear stability analysis shows that implicitness offers benefits, and a natural analogue of mean-square A-stability i...

in this paper, a viscous flow simulation is presented using the lattice boltzmann equation (lbe). a finite volume approach is adapted to discretize the lbe on a cell-centered, arbitrary shaped, rectangular tessellation. the formulation includes upwind scheme and high order descretization schemes for the flux term and collision operator respectively. a consistent open and solid boundary treatmen...

Visual control based on image features has received much attention for its inherent robustness against camera calibration errors, modelling uncertainties and the capability to keep object in Field of View (FoV) camera. Nevertheless, some drawbacks related basin convergence existence local minima, which make get stuck undesired equilibrium points, are still worth being investigated. Nowadays, av...
