  • Coupling schemes for cluster synchronization in

    2004-10-15 · We propose an approach to constructing different coupling schemes to stabilize selected cluster synchronization patterns for coupled Josephson equations. In particular, we select a coupling scheme to create synchronization with frequency ratio m 1 : m 2 : ⋯ : m n , which can be arbitrarily chosen and is independent of the frequencies of the uncoupled oscillators.

    2013-1-1 · We propose two novel XFEM-based schemes to couple the equations governing hydraulic fracture propagation. The first scheme uses the XFEM to resolve the Neumann to Dirichlet (ND) map with O (h 2) accuracy and is suitable for fluid fronts that lag behind the fracture front. The second scheme uses a mixed XFEM formulation to enable singular tip asymptotic behavior to be combined with the O (h 2) …

Then, with the aid of the spectral data of Group 15 elements, it becomes clear that the assumption of the L-S coupling scheme is no longer valid as we go farther and farther down the Periodic Table.

On the other hand, a combination of either dynamic relaxation or quasi-Newton together with a mechanical predictor improves the situation significantly even for large coupling …
