spectroscopy computing/ FTIR spectraartificial neural networksIn order to improve the training speed and increase the predictive ability of artificial neural networks, principal component analysis (PCA) and partial least squares (PLS) were introduced to compress the original data. The principal components...

Interpretation of Fourier Transform Infrared Spectra (FTIR): A Practical Approach in the Polymer/Plastic Thermal DecompositionAtomic bonding... AB Nandiyanto,R Ragadhita,M Fiandini - 《Indonesian Journal of Science & Technology》 被引量: 0发表: 2022年 fundamental studies on the diffusional mobility...
however, this possibility has hardly been used for the interpretation of measurement curves. In the following article, we present a database in which DSC curves, characteristic values, and FTIR spectra of more than 600 commercially available materials are stored....
In this work, ATR-FTIR spectroscopy with chemometric tools has been used to estimate the age and sex from fingernails by analyzing 140 fingernail samples (70 males, and 70 females) collected from volunteers aged between 10 and 70 years old. The amide bands obtained from spectra confirmed the ...

A spectroscopic investigation of the carrageenans and agar in the 1500-100 cm−1 spectral range Fourier transform infrared (FTIR) and Raman spectra in the 1600-100 cm−1 range have been employed in a structural analysis of biopolymers of the polygal... SP Legrand - 《Spectrochimica Acta ...
The painted layers were applied over gypsum and glue, as revealed by FTIR analysis and UV fluorescence examination of the cross sections. Glue exhibits a light blue fluorescence under UV lighting. At last, in sample ASN2 and ASN4 an orange UV fluorescence can be observed. This fluorescence ...
The technique of Fourier transform infrared (FTIR) spectroscopy, in conjunction with new methods of sample presentation, has been used to study biopolymer functionality in aqueous systems. Changes in the spectra of kappa-carrageenan gels have been observed with both counter-ion and temperature. Most ...
