In this study we apply Zipf-Alecseev’s function to
word length distributions of Chinese prose and dialogue texts. Since there are
two potential measurement units of Chinese word length, we applied
Zipf-Alecseev’s function to both of them.
The results show that all the word length distributions fit Zipf-Alecseev’s
function, no matter the word length is measured in characters or
components. The parameters ...

In order to solve the lack
of automatic transmission slippage fault data, the uncertainty of the link
between the source of the fault and the degree of failure, the lack of
applicability of the traditional Boolean logic gate, the T-S model and fuzzy
theory and the revision of the confidence index are proposed. The expert survey
method was combined and the analysis method was introduced into the fault tree.
The T-S model is introdu ...

In order to solve the
difficulty of the arrangement of ore production at each mine site during the
transition from open pit to underground mining in Shirengou iron mine. Taking
the largest amount of mining as the objective function, each deposit storage capacity,
ore dilution rate, ore loss rate and grade as the constraints, thus the linear

Magnetorheological Fluid (MRF), as an advanced and smart material which was controlled
by magnetic field, was a kind of stable suspension in which magnetic particle dissolved
in base fluid. The yield stress, one of main performance parameters of MRF, was
the demarcation point between liquid and solid. At present, the yield stress calculation
model did not have a uniform standard. The research on yield stress model was s ...
