Flow Equation Approach to Periodically Driven Quantum Systems"

DC power

flow equation is linearization method, however it has neither enough accuracy nor show what is happening in the line loss.

[14,15] figured out the

flow equation of viscoelastic fluid in micro porethroats and numerical solution of flow field, including velocity field and stress field, with upper-convected Maxwell constitutive equation, compared the flooding force on residual oil by different viscoelastic flooding fluids and corresponding residual oil deformation, and obtained hydrodynamic mechanism of elastic flooding of residual oil drop.

A complete theory of groundwater flow when rainfall infiltrates unsaturated zones can be described using either the variably saturated

flow equation or the generalized Richards equation.

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].

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.

A solution [bar.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.M] [right arrow] [bar.M] such that [bar.g](t) = [phi](t)[psi][(t).sup.*][bar.g](0), where f'(t) = -2A for a constant A.

The

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

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

flow equation. Field technicians can play a larger decision-making role.

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).
