Temperature Dependent NIR Spectroscopic Analysis for Food Grain Samples

NIR Spectroscopy - A guide to near-infrared spectroscopic analysis

NIR spectroscopic properties of aqueous acids solutions.

Acid content is one of the important quality attributes in determining the maturity index of agricultural product, particularly fruits. Despite the fact that much research on the measurement of acidity in fruits through non-destructive spectroscopy analysis at NIR wavelengths between 700 to 1,000 nm has been conducted, the same response towards individual acids is not well known. This paper pre...

Temperature-Dependent Buckling Analysis of Functionally Graded Sandwich Cylinders

This study is limited to study of buckling analysis of a sandwich cylindrical shell with functionally graded face sheets and homogenous core. High-order sandwich plate theory is improved by considering the in-plane stresses of the core that usually are ignored in the analysis of sandwich structures. Assume that all properties of the face sheets and the core are temperature dependent. Strain com...

Diffuser-incorporated transmission NIR measurement for reliable analysis of packed granular samples.

A diffuser-incorporated transmission near-infrared (NIR) scheme that enables direct spectral collection of packed granular samples with reliable sample representation and reproducibility has been demonstrated. The analytical utility of this method has been evaluated for the determination of polyethylene (PE) pellet density and the discrimination of the geographical origin of rice samples. Based...

Image analysis of bulk grain samples using neural networks

Visen, N.S., Paliwal, J., Jayas, D.S. and White, N.D.G. 2004. Image analysis of bulk grain samples using neural networks. Canadian Biosystems Engineering/Le génie des biosystèmes au Canada 46: 7.117.15. Algorithms were developed to acquire and process color images of bulk grain samples of five grain types, namely barley, oats, rye, wheat, and durum wheat. The developed algorithms were used to e...
