The adaptation and use of advanced technologies is an effective and encouraging way to efficiently and reliably characterise crops and plants. Additionally advances in these technologies will improve the information available for agronomists, breeders and plant physiologists in order to develop best management practices in the process and commercialization of agricultural products and commoditi...

Near Infrared (NIR) spectroscopy has been used for timber, pulp and paper applications for over 20 years. Despite a lot of R&D work on solid wood applications for both field and in-process use, the industry has not adopted NIR as a routine technique. Solid wood has proven to be a challenging sample type to analyse in real time by NIR as the modern timber mill processes logs at a very fast rate....

A NIR method was developed for the on-line monitoring of alkali-free cloth/phenolic resin prepreg during its manufacturing process. First, the sizing content of the alkali-free cloth was analyzed, and then the resin, soluble resin and volatiles content of the prepreg was analyzed simultaneously using the FT-NIR spectrometer. Partial least square (PLS) regression was used to develop the calibrat...

We discuss a cryogenic, multi-object near-infrared spectrometer as a second generation instrument for the VLT. The spectrometer combines 20 to 40 independent integral field units (IFUs), which can be positioned by a cryogenic robot over the entire unvignetted field of the VLT (∼7’). Each IFU consists of a contiguous cluster of 20 to 30 pixels (0.15 to 0.25” per pixel). The individual IFUs have ...

Automatic control of a fluidized-bed drying process depends on the availability of an inline sensor to provide accurate measurements of product moisture content. Nearinfrared (NIR) spectroscopy technology provides a potentially noninvasive and nondestructive analytical method that could serve as a sensor option for a wide range of applications. The purpose of this research was to investigate th...

Soil types have traditionally been determined by soil physical and chemical properties, diagnostic horizons and pedogenic processes based on a given classification system. This is a laborious and time consuming process. Near infrared (NIR) spectroscopy can comprehensively characterize soil properties, and may provide a viable alternative method for soil type recognition. Here, we presented a pa...

this paper reports on the use of artificial neural networks (ann) and partial least squareregression (pls) combined with nir spectroscopy (900-1700 nm) to design calibration models for thedetermination of sugar content in sugar beet. in this study a total of 80 samples were used as the calibration set,whereas 40 samples were used for prediction. three pre-processing methods, including multiplic...

Spectroscopic methods provide with very useful qualitative and quantitative information about the biochemistry and chemistry of antioxidants. Near infrared (NIR) and mid infrared (MIR) spectroscopy are considered as powerful, fast, accurate and non-destructive analytical tools that can be considered as a replacement of traditional chemical analysis. In recent years, several reports can be found...
