Differentiating with fluorescence spectroscopy the sources of dissolved organic matter in soils subjected to drying

abstract：:The investigation of object-by-attribute matrices is very common in statistics and data analysis with the aim of uncovering every possible relationship among objects and/or attributes. Formal Concept Analysis (FCA) is a method, which stems directly from partial order and lattice theory, which provides an efficient too...
