The subject of the public contract is the delivery of a compact table microplate reader designed to measure the absorption of biological samples in the ultraviolet (uv) and visible (vis) spectral regions
for determining the concentrations of biological analytes and macromolecules and analyzing enzyme activity.
Consequently, the spectral regions
and bands sensitive to yellow rust were found out (Fig.
Ushio's expertise in manufacturing specialized UV products, uniquely designed to provide light rich in the ultraviolet spectral regions
Multivariate calibration was preliminarily developed from 90 spectra, using different spectral regions
and various types of pre-signal processing (mean centering, auto-scaled, smoothed-derived and submitted to MSC).
PCA was used for preliminary data analysis: detecting outlier spectra and the specification of important spectral regions
The prediction results of N, P, and K by LS-SVM model in the NIR, MIR, and combined NIR-MIR spectral regions
are shown in Table 3.
The multi-variate regression coefficient information shows the dominant spectral regions
that feed the model prediction below it (figure 5).
Amateurs are now routinely monitoring the Sun in exotic spectral regions
such as hydrogen-alpha (Ha) and calcium K (CaK), where particularly exciting features become visible.
The 20/20 PV Microspectrophotometer, from CRAIC Technologies, captures spectra and images of microscopic samples in the ultra-violet, visible, and near infrared spectral regions
It has been demonstrated that the spectral regions
at or around 450, 530, and 610 nm are uniquely efficient at stimulating the visual system when targeting increased brightness and color perception per watt [for example, Thornton 1992a 1992b 1992c, Houser and Hu 2004, Houser and others, 2004].
Headwall's ability to manufacture application-specific sensors for spectral regions
of interest affords our customers with well-differentiated capabilities.
Different spectral regions
were tried for each extraction system and its effect on the correlation and prediction accuracy was assessed until the best correlation was obtained.
