A novel graph seriation method based random graph theory is proposed in this paper. By seriation processing, graphs can be converted to string through constructing toroidal catch digraph. Seriated graph distance is using to represent the similarity between graphs. It measures the structural differences between graphs based on the dynamic warping technique. Dynamic time warping distance used in the paper is evaluated by dynamic programming. The results of our experiments demonstrate that the proposed method is eligible for graph distance measure
In this paper, the kurtosis-based method for the classification of mental activities is proposed. The EEG signals were recorded during imagination of left or right hand movement. The kurtosis of EEG and its dynamic pr...

The quotient space theory is indented to study the relationship of transform and that of dependency among the worlds with different grain-size. Compared-with other granule computing tools, it has more powerful abilities of representation and absorption. The reason is that structure is introduced in its model The paper is to study the quotient space theory based on structure. We first introduce some methods of constructing quotient structure. Then we study in detail the quotient space family based on structure, and get some good results for further research. Finally we also briefly discuss hierarchical structure of fuzzy sets.

The paper presents an approach to optimize the protein 3D HP model conformation with ant colony optimisation (ACO). A rapid coordinate system transfer matrix according to the "right hand" rule we defined is used to reduce the computing time. A new scheme to solve the problem of folding deadlock is suggested. During the update of pheromone, a new update method with dynamic pheromone is given and three local search methods are provided. Using these methods, 3D conformation of standard test sequences with very low energy was found

This paper proposes a new approach of human face recognition using partial least square (PLS) and covering algorithm. PLS constructs the component so that the correlation between the class variable and themselves maximized. Covering algorithm is a kind of neural network method. The approach first processes the image with wavelet transform, and then eliminates the redundant features with PLS. It reduces the dimension of image by extracting the principal features. Finally, classifies the image by covering algorithm

Multi-carrier (MC) CDMA technique can reduce the interference and improve the performance of the system in fading channel. But the frequency offset and multiple access interference (MAI) are obstructive to its performance. In this paper, combining the PIC multiuser detection and frequency offset estimation based on maximum likelihood function guard interval, we propose a joint detection which called M-ML-MPIC (Modified Maximum Likelihood Multistage Parallel Interference Canceller) to correction the frequency offset and MAI simultaneously. The numerical results of the performance analysis and comparisons of conventional schemes with the proposed method are given.

In this paper, we offers a new algebraic point of view for DNA molecules and introduce the algebraic system by using the natural operation based on the Sigma = {A, C, G, T} . We characterize its structure by using the algebraic theory. We show that (L, oplus, otimes ) is the distribution lattice of rings with identical element. Furthermore,we generalize this result to the Wrho(V) , a set which elements simulates the DNA molecules with sticky ends, the element is called an incomplete double stranded molecules consist of mixed DNA molecules with double and single strands.

At present the most widely used technology of pinyin-Chinese character conversion combines statistics with linguistic rules. Although it basically solves such problems as long distance restriction and language recursion phenomenon,it relies on a great deal of computation because there are too many candidate paths. This paper tries to simplify the candidate paths by using quotient space granularity computation theory, first obtains the scope of the best path in the coarser granularity world, and then uses more language rules to obtain the best path. The experiments indicate that this method can reduce the computation, speed up the conversion, and enhance the rate of accuracy by nearly 2％.
