Extrapolation errors of force transducer curve fitting equations
Universitas Scientiarum, 2022 Calibration laboratories often face the challenge of the impossibility to perform full capacity range calibration of their force transducers, particularly below 10 % of the force transducer’s capacity.

Functional Curve Fitting Algorithm via Multi-Heterogeneous Data Curve
IEEE Access, 2017 Complex computing based on multi-heterogeneous parameters can utilize the Lebesgue measure to measure their linear and non-linear relations in infinite dimensional Hilbert space, which can characterize those different dimensional characteristics in a set

The Mittag-Leffler Fitting of the Phillips Curve
Mathematics, 2019 In this paper, a mathematical model based on the one-parameter Mittag-Leffler function is proposed to be used for the first time to describe the relation between the unemployment rate and the inflation rate, also known as the Phillips curve. The Phillips

Neural-Network-Based Curve Fitting Using Totally Positive Rational Bases
Mathematics, 2020 This paper proposes a method for learning the process of curve fitting through a general class of totally positive rational bases. The approximation is achieved by finding suitable weights and control points to fit the given set of data points using a ...

Spectral curve fitting of dielectric constants
AIP Advances, 2017 Optical constants are important properties governing the response of a material to incident light. It follows that they are often extracted from spectra measured by absorbance, transmittance or reflectance.

Equivariant adjusted least squares estimator in two-line fitting model
Modern Stochastics: Theory and Applications, 2016 We consider the two-line fitting problem. True points lie on two straight lines and are observed with Gaussian perturbations. For each observed point, it is not known on which line the corresponding true point lies.

Sicegar: R package for sigmoidal and double-sigmoidal curve fitting [PDF]
PeerJ, 2018 Sigmoidal and double-sigmoidal dynamics are commonly observed in many areas of biology. Here we present sicegar, an R package for the automated fitting and classification of sigmoidal and double-sigmoidal data.

Curve Fitting-Based Phase Optimization for Microwave Power Transfer
IEEE Access, 2022 Microwave power transfer provides power wirelessly by converting electromagnetic waves emitted by an antenna to DC power using a rectifying antenna (rectenna). We are developing a distributed cooperative power transfer system that intentionally generates
