The main objective of the OPF problem is to optimize a chosen objective function such as fuel cost, voltage profile improvement, voltage stability enhancement, through optimal adjustment of power system control variable while at the same time satisfying system operation condition with power

flow equation and inequality constraints [1-4].

Therefore, the simplified

flow equation as shown in Equation (4) was used to replicate the second flow scenario.

In fact, they say, the solution of the non-linear

flow equation leads to a diagonalization of Hamiltonian operators in boson quantum field theory that are quadratic in the field.

According to different boundary conditions and parameters, the novel slip model, and the

flow equation were transformed into the no-slip model, the adsorption-desorption model, the entanglement-disentanglement model, the lubrication layer slip model, and Z-W slip model.

The

flow equation is based on the step structure of the cushion structure.

g](t) of the Ricci

flow equation (4) is called "Ricci soliton" if there exists a positive function [phi](t) and a 1-parameter family of diffeomorphisms [psi](t) : [bar.

Technicians can be proactive in avoiding issues by seeing how each data point fits into an overall

flow equation.

If the mean velocity and area at the hood face can be ascertained, then the basic

flow equation can be solved [Q = U A] (ACGIH, 2004).

But a unique term can be added to (3) that generalises the

flow equation, but also preserves the Keplerian nature of the planetary motions that underlie Newton's gravity formalisation:

The

flow equation (10) coupled with energy equation (15) constitute a set of highly nonlinear differential equations.

These standard forms of the unsaturated

flow equation may be identified as: the '[psi]-based' form, the '[theta]-based' form, and the 'mixed form.

On the other hand, the significant and positive sign found in the

flow equation indicates that the new crop of FDIs to Africa might be market and resource seeking.
