The power stage of the PV emulator is realized using dc-dc buck converter topology and the controller stage uses an algorithm-in-loop Newton-Raphson (NR) method. Finally, the PV emulator is tested with MPPT con
The key idea in PSNA is using the Newton-type method SNA to iteratively identify the active set using both the primal and dual information, then solve the problem on the active set. In this section we discuss the connections between PSNA with other three dual active set methods, i.e., ...
Muller’s method is generalized a form of the secant method. This method was developed in 1956 by David Muller. It is generally used to locate complex roots of an equation. Unlike the Newton Raphson method, it doesn’t required the derivation of the function. The convergence in Muller’s ...
Herein, we assume that the Newton–Raphson method is used [10]. Because the finite element method is well known, the ensuing derivation Example problems The authors have chosen to model the SCS-6/Timetal21S[O]4 metal matrix composite for illustrating the use of the three-dimensional cohesive...
The performance of MF-DIC is well validated following the method in DIC challenge 2.0 [37]. • IC-GN is used to alleviate the repeated evaluation of the Hessian matrix involved in the forward-additive Newton– Raphson method. The paper is organized as follows. "General Digital Image ...

The algorithm includes the correction of the sought-for ice and ponds characteristics with the iterative procedure based on the Newton–Raphson method. Also, it accounts for the bi-directional reflection from the ice/snow surface, which is particularly important for Arctic regions where the sun is...
For transient analysis, components are represented in differential or integral form. Non-linear elements are solved by an iterative method (e.g. Newton-Raphson) at each time step. An initial guess at the node voltages is created. The slope and intercept of the tangent to the actual I-V cur...
The Newton-Raphson method is often used to find the reciprocal of a number, since fully accurate reciprocal functions are often costly to implement in hardware due to their long latency, complexity and large circuit area. Plugging the reciprocal function into this equation becomes: ...
In theory, other numerical optimization techniques, such as gradient descent or Newton-Raphson, could be used instead of expectation maximization; in practice, however, expectation maximization has the advantage of being simple, robust and easy to implement. Applications Many probabilistic models in ...
