The phrase "accuracy of the first" is correct and usable in written English.
It can be used when discussing the precision or correctness of an initial item, measurement, or statement in a comparison or analysis.
Example: "The accuracy of the first experiment was crucial in establishing a reliable baseline for our research."
Alternatives: "precision of the initial" or "correctness of the first".
Four independent approaches are then applied to identify the best-fit model and the accuracy of the first derivative.
The approach proposed here combines the accuracy of the first method with the simplicity of the second.
The implemented networks improved the signal amplitude ratio between the first resonant mode and the other modes, increasing the identification accuracy of the first resonance peak.
This formulation aims to improve the accuracy of the first order perturbation method, and also allow the efficient computation of higher order statistical moments of the eigenparameters.
A Fourier technique is used to estimate the accuracy of the first- and second-order approximations and indicates that for even small perturbations, second-order terms are significant.
The accuracy of this reconstruction depends on accuracy of the first and second-order derivatives of the plate stress resultants, which is not guaranteed by most available low-order plate finite elements.
The accuracy of the first-principle models describing the evolution of gas dynamics in pipelines is sometimes limited by the lack of understanding of the gas transport phenomena.
Two systems involving nth-order heterogeneous catalytic reaction and diffusion transport were used to illustrate the application and accuracy of the first-harmonic balance methods.
In this paper we present a delicately designed numerical experiment to explore the relationship between the accuracy of the first-order derivative (FOD) formula and the one of the main structure in an Obrechkoff method.
Numerical examples are used to demonstrate the improved accuracy of the fourth-order method.
Numerical tests show an important improvement in the accuracy of the fourth-order scheme.
