We have employed a flux-flux cross-correlation function approach (CCFA) to calculate quantum thermal rate constants of reactions for which an auto-correlation function approach (ACFA) is not adequate. In CCFA, two dividing surfaces partition a system into three regions, while in ACFA, two channels are defined by a dividing surface. Therefore, the CCFA method is appropriate for multi-channel reactions. In this paper, we show the efficiency of CCFA for multi-channel reactions. For example, we have examined self-diffusion of a hydrogen atom on a rigid Cu (111) surface. We introduce closed dividing surfaces that subdivide the potential energy surface for each channel. A combination of the closed dividing surfaces and CCFA allows us to calculate rate constants for both single and multi-hopping modes directly. Then, we calculate a diffusion constant without the usual uncorrelated hops approximation, using instead the calculated site-to-site hopping rates, thus showing the importance of multihops.

The proposed Icos⁡ϕ control technique has been applied for power quality improvement using different configurations of system with distribution static compensator (DSTATCOM). Modeling, design and control of DSTATCOM are analysed in detial. Three phase reference current are extracted with this technique. The proposed technique has been used for power factor enhancement, voltage regulation, harmonic suppression and load balancing under dynamic condition with non-linear load. The proposed control is very effective for three different configurations of system with DSTATCOM for power quality improvement. Results for each configuration of system with DSTATCOM are simulated using MATLAB/Simulink sim power tool box. For teaching the power quality course, these can also be helpful.
