Equation (1) has been solved by different techniques such as finite-difference method (FDM) [4], fast-Fourier-transform-based (FFT) methods [5], finite-element method (FEM) [6], the spectral-element method [7], compact finite-difference method [8], and multigrid methods [9].
The method is designed to be used with a barotropic baroclinic splitting that separates the fast and slow motions into subsystems that are solved by different techniques.
In a number of ocean models, the computational problems resulting from the multiple time scales are addressed by splitting the fast and slow dynamics into separate subproblems that are solved by different techniques.
Using the fitted second order models for the separation criteria, a refined Pareto optimal combination was obtained as the solution of the multicriteria optimization (maximization) problem that was solved by different methods (Weighted Sum of Objectives, Goal Programming and Desirability Functions).
Various hydrological problems of ungauged watershed are solved by different regional hydrological models which are developed using geomorphological characteristics of the watershed.
where the disturbance input e ( t ) is a white noise random signal with spectral density S e S e = σ e 2. As mentioned before, up to now, problem (19) has been solved by different methods such as LQG, MPPT, sliding mode, and fuzzy techniques.
Simultaneous linear equations are equations with two different variables or unknowns that can be solved by three different methods.The three methods are: Elimination, Substitution, and Graphical Solution.
