As a common geological material, soil is key aspect of construction engineering. Soil has typical multi-scale characteristics, but current methods analyze these characteristics only in regard to geometric space. More exploration the coupling influence mechanism basic properties particles on microstructure and macroscopic needed. This study analyzed scale mineral composition surface energy at mi...

In this paper, we propose a new method to analyze the difference and similarity of biological sequences, based on the fuzzy sets theory. Considering the sequence order and some chemical and structural properties, we present a computational method to cluster the biological sequences. By some examples, we show that the new method is relatively easy and we are able to compare the sequences of arbi...
