Near-infrared reflectance spectroscopy (NIRS) analysis is based on the development of calibration equations that relate constituents and the infrared information spectrum. This study compares 2 chemometric tools for developing NIRS prediction models: the GLOBAL modified partial least squares and the recently calibration strategy known as LOCAL. The LOCAL procedure is designed to select, from a ...

Computer models to simulate physical phenomena are now widely available in engineering and science. Before relying on a computer model, a natural first step is often to compare its output with physical or field data, to assess whether the computer model reliably represents the real world. Field data, when available, can also be used to calibrate or tune unknown parameters in the computer model....

This work presents a strategy for automatic analysis of photoelastic fringe patterns. The study is focused on the analysis of color type photoelastic fringes. By capturing and analyzing color fringes automatically, the difference between principal stresses of a sample are quantitatively determined. Among many techniques available in literature, the color photoelasticity is chosen as the basis f...
