Fuzzy Rough Sets Theory Reducts for Quantitative Decisions – Approach for Spatial Data Generalization [chapter]

Anna Fiedukowicz
2015 Lecture Notes in Computer Science  
The proposed method is based on the tnorm of fuzzy indiscernibility based on attribute value and fuzzy indiscernibility based on decision, which is calculated for each pair of objects.  ...  Such tools as reducts and fuzzy reducts, though useful, are still insufficient for the quantitative decisions, common in cartographical generalization.  ...  The discernibility matrix then, existing also in the traditional fuzzy sets theory, is filed with the measure of closeness (based on each attribute) for each pair of objects with different decision value  ...

The effect of numerical aperture on quantitative use-wear studies and its implication on reproducibility

Ivan Calandra, Lisa Schunk, Konstantin Bob, Walter Gneisinger, Antonella Pedergnana, Eduardo Paixao, Andreas Hildebrandt, Joao Marreiros
2019 Scientific Reports  
The results demonstrate that 3D surface texture ISO 25178 parameters differ significantly when the same surface is measured with objectives having different numerical apertures.  ...  We argue that to move use-wear analysis toward standardization, repeatability and reproducibility, the first step is to report all acquisition and analysis settings.  ...  Therefore, a roughness standard with nominal Ra = 0.40 ± 0.05 μm was measured with each of the two objectives. The measured Ra values were then compared to the nominal value. Data acquisition.  ...
