NIR Model Transfer Based on Wavelet Transform Algorithms
June 1st 2013A study is presented that uses an amine mixture as an example to discuss the combination of wavelet and piecewise direct standardization algorithms, which will improve the precision of near infrared (NIR) model transfer.
Calibration Transfer, Part III: The Mathematical Aspects
June 1st 2013Calibration transfer is a series of techniques used to apply a single spectral database, and the calibration model developed using that database, to two or more instruments. Here, we review the mathematical approaches and issues related to the calibration transfer process.
Out of This World: The Next Generation of Medical Diagnosis
June 1st 2013Real-time air fingerprinting (RAFT) uses spectroscopic techniques to measure volatile organic compounds. Now, the University of Leicester in the UK is testing the use of RAFT for rapid and noninvasive diagnosis of illness in an emergency ward. Paul Monks, a professor in atmospheric chemistry and earth observation science, explains the approach.
