Summary:
This paper presents the application of a dielectric resonator sensor to characterize glycerin solutions. Air and nine different concentrations were measured within a relative permittivity range from 1 to 78.3. Principal Component Analysis (PCA) and Support Vector Machine (SVM) were used to perform automatic classification with an 100% accuracy and the regression of both concentration and permittivity with a RMSE of 0.34% and 0.287 respectively.
Layman's summary:
Este artículo presenta la aplicación de un sensor resonador dieléctrico para caracterizar disoluciones de glicerina. Se midieron nueve concentraciones diferentes dentro de un rango de permitividad relativa de 1 a 78,3. Se utilizó el análisis de componentes principales (PCA) y la Support Vector Machine (SVM) para realizar una clasificación automática alcanzando una precisión del 100 %;. También se realizó una regresión para estimar tanto la concentración de glicerina como de la permitividad de la disolución, alcanzando un RMSE de 0,34 % y 0,287 respectivamente.
