dycdtools: an R Package for Assisting Calibration and Visualising Outputs of an Aquatic Ecosystem Model [PDF]

open access: yes, 2023
The high complexity of aquatic ecosystem models (AEMs) necessitates a large number of parameters that need calibration, and visualisation of their multifaceted and multi-layered simulation results is necessary for effective communication. Here we present

Nearest Correlation-Based Input Variable Weighting for Soft-Sensor Design

open access: yesFrontiers in Chemistry, 2018
In recent years, soft-sensors have been widely used for estimating product quality or other important variables when online analyzers are not available. In order to construct a highly accurate soft-sensor, appropriate data preprocessing is required.

Model Calibration and Validation for the Fuzzy-EGARCH-ANN Model

open access: yesApplied Computational Intelligence and Soft Computing, 2021
This work shown as the fuzzy-EGARCH-ANN (fuzzy-exponential generalized autoregressive conditional heteroscedastic-artificial neural network) model does not require continuous model calibration if the corresponding DE algorithm is used appropriately, but ...

Investigation of NIR spectra pre-processing methods combined with multivariate regression for determination of moisture in powdered industrial egg

open access: yesActa Scientiarum: Technology, 2018
High productivity and meantime perishability of in natura eggs, make powdered egg attractive for patisseries and pasta industries. Water reduction in 65%, extends shelf life from 1 to 12 months, preventing also Salmonella.

Multiport network analyzer self-calibration: a new approach and some interesting results [PDF]

open access: yes, 1997
A new approach to multiport network analyzer calibration is here presented. This solution exploits the redundancy of multiple standards connections in order to perform a multiport self-calibration.

Towards dynamic camera calibration for constrained flexible mirror imaging [PDF]

open access: yes, 2008
Flexible mirror imaging systems consisting of a perspective camera viewing a scene reflected in a flexible mirror can provide direct control over image field-of-view and resolution. However, calibration of such systems is difficult due to the vast range

Lactoferrin content determined in bovine milk by HPLC and mid-infrared spectrometry - Relation to udder health and potential for detection of milk adulteration

open access: yesCzech Journal of Animal Science
Lactoferrin (LF) is a multifunctional glycoprotein linked to udder health in dairy cows. This study aimed to develop a calibration model for LF quantification using mid-infrared spectrometry (MIR-FT), with ion-pair reversed-phase high-performance liquid ...
