Multivariate Curve Resolution Methodology Applied to the ATR-FTIR Data for Adulteration Assessment of Virgin Coconut Oil

open access: yesMolecules, 2023
Virgin coconut oil (VCO) is a functional food with important health benefits. Its economic interest encourages fraudsters to deliberately adulterate VCO with cheap and low-quality vegetable oils for financial gain, causing health and safety problems for ...

Testing of calibration models in order to certify the overall reliability of the trisonic blowdown wind tunnel of VTI [PDF]

open access: yesFME Transactions, 2010
It is strongly recommended that wind tunnel calibrations become a regular part of the operational cycle for any wind tunnel. They facilitate tunnel-totunnel data comparisons. Standard calibration model, representing a generic winged missile configuration,

Calibrating a flow model in an irrigation network: Case study in Alicante, Spain

open access: yesSpanish Journal of Agricultural Research, 2017
The usefulness of models depends on their validation in a calibration process, ensuring that simulated flows and pressure values in any line are really occurring and, therefore, becoming a powerful decision tool for many aspects in the network management

Sequential calibration of material constitutive model using mixed-effects calibration

open access: yesMechanics & Industry, 2023
Identifying model parameters is nowadays intrinsically linked with quantifying the associated uncertainties. While classical methods allow to handle some types of uncertainties such as experimental noise, they are not designed to take into account the ...

Integrating remote sensing datasets into ecological modelling: a Bayesian approach [PDF]

open access: yes, 2008
Process-based models have been used to simulate 3-dimensional complexities of forest ecosystems and their temporal changes, but their extensive data requirement and complex parameterisation have often limited their use for practical management ...

DIC-Aided Mechanoluminescent Film Sensor for Quantitative Measurement of Full-Field Strain

open access: yesSensors
To break through the bottleneck in the mapping of the mechanoluminescent (ML) intensity field to the strain field, a quantification method for full-field strain measurement based on pixel-level data fusion is proposed, integrating ML imaging with digital

Comparative study between local and global optimization for Heston model

open access: yesRatio Mathematica, 2022
The objective of this study is to estimate the calibration parameters of the Heston stochastic volatility model by the two optimization methods: local and global, then to compare their performances and finally to recommend one of the two methods.
