This paper proposes two methods for solving the expert finding problem. In order to enhance the correctness, a C-value method is applied to these methods for query expansion. After query expansion, proposed system calculates correlation between all query terms and experts, and finally outputs a list of experts. The experiment results show that the proposed methods can provide higher precision than...
In this paper, by comparing among different equations of state, we would like to find one equation of state, which can be applied in wide range of pressures for fcc metals. The equations of state for fcc metals: Al, Cu, Ag have been studied with ultrasonic data. Compared with experimental DAC data, it is found that there is no equation of state, which can describe the compressibility for any materials...
Second-order hidden Markov models (HMM2) have been widely used in pattern recognition, especially in speech recognition. Their main advantages are their capabilities to model noisy temporal signals of variable length. In this article, we introduce a new HMM2 with multiple observable sequences, assuming that all the observable sequences are statistically correlated. In this treatment, the multiple...
