3]) and [beta] (unitless) are the material constants determined via curve fitting.
Treatment of several mathematical topics follows, including Taylor series, matrices, root-finding, numerical integration, ordinary differential equations, and curve fitting.
In addition to the curve fitting precision, the uncertainty in the in-situ characteristic curve is also caused by uncertainty in each of the physical sensors as well.
Curve Fitting by Lines or Polynomials (Linear Regression)
The results of curve fitting indicated that a consideration of reproductive energy is meaningful for model extension.
In this paper, the dot area parameters of two equations are re-explained as the color percentage at first to make the corrected equations applied to the non-printing dot image of color image; then improve the contraction-expansion curve fitting algorithm to enhance the search efficiency and reduce the computation load; and study and make up the color error of color scanner step by step by the order of single color, double colors and three colors in accordance with the scanner's coloration principle and correct the equations step by step so as to overcome the problem that the black box algorithm does not consider the intermediate color conversion process and cause low accuracy.
When curve fitting data for control systems, it is always a good idea to include pseudo data in the dataset at the extreme ranges of expected operating conditions if measured values do not exist.
The purpose of presented research is to develop and verify an efficient method for curve fitting, which can be used in modeling and analysis of the road centerline axis geometry.
The error of scale factor has been investigated and mainly compensated by employing the 1th order curve fitting in least squares [12].
It is possible to resolve the nonassociated and the associated carbonyl bands using spectral curve fitting method described previously (14-18) using Gaussian function.
The relationship between the three measures of corrosion damage and the quantitative variables describing the properties and chemistry of the soils at the sites were explored by plotting the standard score for the variables at the site against the corrosion damage measure and performing linear regression on the measurements using commercially available curve fitting software.
