A less conservative approach to handle time-varying parameters in discrete-time linear parameter-varying systems with applications in networked control systems
(2020)This article proposes a new strategy to deal with linear parameter-varying discrete-time systems, whose time-varying parameters can be written as solutions (such as exponential, trigonometric, or periodic function) of a ...

A method to construct fruit maturity color scales based on support machines for regression: Application to olives and grape seeds
Mora, Marco
; ; ; ; Fredes, Claudio (2015)
Color scales are a powerful tool used in agriculture for estimate maturity of fruits. Fruit maturity is an important parameter to determine the harvest time. Typically, to obtain the maturity grade, a human expert visually ...

A method to estimate grape phenolic maturity based on seed images
; Mora, Marco; Fredes, Claudio (2014)
The timing of the grape harvest has a strong impact on wine quality. A recent line of studies proposes visual seed inspection by a trained expert to determine Phenolic Maturity. In this paper a method is presented to ...
-
A model based on clusters of similar color and NIR to estimate oil content of single olives
Fredes, Claudio; ; ; Mora, Marco ; ; ; (2021)
Lipid extraction using the traditional, destructive Soxhlet method is not able to measure oil content (OC) on a single olive. As the color and near infrared spectrum are key parameters to build an oil estimation model (EM), ...
