Deterministic methods include Newton’s method (Li et al., 2013), Newton–Raphson method (Chan et al., 1986), iterative curve fitting (Elbaset et al., 2014), and other methods. These methods are greatly affected
The corresponding values are obtained at each time by inverting the global PQ function (employing a Newton–Raphson algorithm) for the set of pumps in service. The algorithm checks that the boundary conditions about the limit values for the flows and powers supplied are satisfied. This function ...
like the Lambert W-based analytical method25,26, have been proposed for accurately determining the PV model parameters. This method is more effective in ease of implementation, robustness, efficiency, and accuracy than other methods. Yet, its application scope is limited and can easily fall into ...
Moreover, a local convergence of the Newton– Raphson method requires appropriate initial condi- tions that may be problematic for a large river network (Yu et al. 2017). Many different schemes for hyperbolic equations that preserve nonnegativity of water flow depth were developed after the ...
The main difficulty was the connection between the initial tool path and the newly inserted smoothing portion of the tool orientation. In order to address this problem, a third parametrization spline was designed to link the bottom and top B-spline parameters using a Newton-Raphson iterative ...
In recent years, several researchers have been interested in looking for accurate parameter identification techniques able to deal with the high non-linearity of the solar cell model. In this regard, we proposed in this paper, the optimization method of Levenberg–Marquardt (LM) combined with simul...
In this strategy, GA was used to extract three parameters, 𝑅𝑠Rs, 𝑅𝑠ℎRsh and 𝑛n whereas 𝐼𝑝ℎIph and 𝐼𝑠Is were extracted analytically using Newton Raphson (NR) method. According to the findings, the NR technique converges quickly when the number of unknowns is ...
The estimated current is determined using the Newton–Raphson method of Equation (3) and the identified parameters. 𝐼𝑒𝑠𝑡=𝐼𝑒𝑠𝑡−𝑑𝐼𝑑𝐼′ Iest=Iest−dIdI′ (3) where 𝑑𝐼dI denotes the difference function of I. The 𝑑𝐼′dI′ symbols are the first ...
