Every time your FEA solver converges on a nonlinear solution, something precise is happening under the hood. It is not magic. It is Newton-Raphson, and it is worth understanding. The idea is geometric ...

The study proposes a fractional-order derivative-based Newton-Raphson algorithm for solving nonlinear fractional-order systems. The algorithm focuses on polynomial, exponential, and trigonometric ...

Abstract: Determining the trim point of an aircraft is essential for designing control law and plays a key role in analyzing flight mechanics and overall performance. This point is obtained by solving ...

Implementation of lower and upper bound approximation algorithms for an NP-hard problem, with heuristics (Greedy, Layout) and metaheuristics (Genetic Algorithm, Simulated Annealing) to balance ...

There are several optimization techniques available in PROC NLMIXED. You can choose a particular optimizer with the TECH=name option in the PROC NLMIXED statement. No algorithm for optimizing general ...

Abstract: Power flow analysis plays a vital role in the planning, operation, and performance evaluation of traction power supply systems (TPSS). However, the unique topology of autotransformer ...
