anti-slide pile is the most commonly used and the most effective control technologies in Slope engineering. The current design theory is based on experiences not to consider soil arching effect, which made reasonable anti-slide pile spacing, is too small and cost is too high. In the paper, by the analysis of existing research results and the two arch-hinged arch optimal curves and instability arch...
A low cost agricultural waste buckwheat hull after extracted natural pigment was used as bisorobent for removal of a cationic dye methylene blue from aqueous solution. The sorbent was characterized by FTIR, scanning electron microscopy (SEM), and potentiometric mass titration. The results showed that buckwheat hull is porous material with functional groups such as hydroxyl and carboxyl, and the pHzcp...
The evaluation outcome often has time lags. As a result, the decision makers often make decision with time lags. In order to deal with the problem, a novel evaluation method based on Markov chain was put forward. Make the mark sequence given by experts for each index a Markov chain, the initial distribution and transition probabilities matrix can be computed based upon the statistical analysis of...
