Near Infrared Reflectance Spectroscopy (NIRS) for rapid determination of biochemical methane potential of plant biomass

Triolo, Jin M.; Ward, Alastair J.; Pedersen, Lene; … - In: Applied Energy 116 (2014) C, pp. 52-57

Determination of biochemical methane potential (BMP) by fermentation tests is time-consuming and costly, and therefore not useful for operators of full-scale biogas digesters. A great advantage of NIRS in determining BMP is the reduction in measurement time from at least one month for chemical...

Utilization of singularity exponent in nearest neighbor based classifier

Jirina, Marcel; Jirina, Marcel - In: Journal of Classification 30 (2013) 1, pp. 3-29

Classifiers serve as tools for classifying data into classes. They directly or indirectly take a distribution of data points around a given query point into account. To express the distribution of points from the viewpoint of distances from a given point, a probability distribution mapping...
