The phrase "a central difference" is correct and usable in written English.
It can be used when discussing a key distinction or variation between two or more concepts, ideas, or entities.
Example: "The central difference between the two theories lies in their approach to understanding human behavior."
Alternatives: "a key distinction" or "a primary difference".
A central difference between the proposals is how much they devote to state and local preparedness.
By using a central difference approximation, curvature mode shapes were then calculated from the displacement mode shapes.
The space discretizaition is performed by employing a finite-volume cell-centered scheme and using a central difference.
The one-dimensional transient heat conduction equation is solved using a central difference scheme in conjunction with the Crank-Nicolson method.
In this paper, a central difference predictive filter (CDPF) is proposed for attitude determination of small satellites with model errors and low precision sensors.
Several schemes for introducing an artificial dissipation into a central difference approximation to the Euler and Navier Stokes equations are considered.
Thirion and colleagues 18 just used a central differencing scheme to calculate the derivatives but after filtering the 3D image with a Gaussian kernel.
In order to identify reversals, the direction of movement, within the coordinate system of the stage, was calculated for each frame using a central differences method, and changes in direction between successive frames were obtained.
It is shown that this method is not directly applicable to the convection diffusion (CD) equation because it results in a central-difference discretization for the convective term.
Significant improvements in the accuracy of a central-difference scheme are demonstrated by computing both inviscid and viscous transonic airfoil flows.
end{cases} Here Δ is a central-difference operator in n defined as Delta = frac{e^{partial_{n}/2} - e^{- partial_{n}/2}}{epsilon}.
