A review of genetic algorithms in near infrared spectroscopy and chemometrics : past and future

, 2008
Global optimisation and search problems are abundant in science and engineering, including spectroscopy and its applications. Therefore, it is hardly surprising that general optimisation and search methods such as genetic algorithms (GAs) have also found

Spectrophotometer ageing and prediction of fruit attributes

, 2016
Walsh, KB ORCiD: 0000-0002-3033-8622Deterioration of lamp output quality over time and degradation of detector signal to noise ratio are issues associated with ageing of a spectrophotometer. To document the effect of instrument ageing on short wavelength

Effects of Assuming Constant Optical Scattering on Haemoglobin Concentration Measurements Using NIRS during a Valsalva Manoeuvre

, 2011
Resolving for changes in concentration of tissue chromophores in the human adult brain with near-infrared spectroscopy has generally been based on the assumption that optical scattering and pathlength remain constant.

The Search for Stable Nickel: Investigating the Origins of Type Ia Supernovae with Late-time Near-infrared Spectroscopy from the Carnegie Supernova Project-II

The Astrophysical Journal
Producing stable ^58 Ni in Type Ia supernovae (SNe Ia) requires sufficiently high-density conditions that are not predicted for all origin scenarios, so examining the distribution of ^58 Ni using the near-infrared (NIR) [Ni II ] 1.939 μ m line may ...
