In the case of evolutionary partial differential equations with higher-order derivatives, IMEX methods can be used to treat the different derivative terms differently. Specifically, the higher-order derivative terms are treated implicitly, while the rest of the terms are treated explicitly. Using IMEX ...
a优化模型的 Optimized model[translate] aHate is dead 怨恨是死的[translate] awhere the high-order derivatives make things much more difficult,but is currently rarely used for the NSWE. 那里高位衍生物做事更多困难,但为NSWE很少当前使用。[translate]...
We propose a high-order integral equation based method for evaluating interior and boundary derivatives of harmonic functions that are specified by their Dirichlet data in planar domains. The tangential derivative of the given Dirichlet data is used to form a complementary Neumann problem, whose soluti...
WSLD operators: A class of fourth order difference approximations for space Riemann-Liouville derivative Because of the nonlocal properties of fractional operators, higher order schemes play more important role in discretizing fractional derivatives than class...

High order methodsSmoothing of initial dataIn this paper, we consider the numerical pricing of financial derivatives using Radial Basis Function generated Finite Differences in space. Such discretization methods have the advantage of not requiring Cartesian grids. Instead, the nodes can be placed with ...
However, frequently measurements or models of FFAG fields postulate their behavior in the midplane only, and rely on the fact that this midplane field and its derivatives determine the field in all of space. The detailed knowledge of the resulting out-of-plane fields is critical for a careful...
In this article, we developed a new higher-order implicit finite difference iterative scheme (FDIS) for the solution of the two dimension (2-D) time fractional Cable equation (FCE). In the new proposed FDIS, the time fractional and space derivatives are
Graphene, graphene derivatives (GNPs, GO and rGO), and EG have been employed as highly conductive additives to enhance the thermal conductivities of PCCs [282]. Owing to their high intrinsic thermal conductivity, Mehrali et al. [55] fabricated a series of PCCs by impregnating PA with various...
In view of the expressions for the cross partial derivatives of the log likelihood function (Eq. (28) in Appendix A.2), Eq. (5) establishes orthogonality of \(\psi \) to \(\alpha \) and \(\beta \) whatever the random effects distribution. The interpretation of the notional parameters...
Examples include Siemens PROFIBUS, Schneider ModBus, and Bosch CAN bus. As new service scenarios constantly emerge, various fieldbus technologies are being replaced by their industrial Ethernet derivatives. For example, PROFIBUS evolves into PROFINET and ModBus transforms into ModBus-TCP. Despite more ...
