摘要：
For cluster head selection randomness of clustering algorithm, and PSOC algorithm were not considered the distance from cluster head to base station, an improved particle swarm optimization (I-PSOC) routing algorithm was brought out. The improved algorithm particle swarm fitness function was improved by considering the node residual energy, nodes' distance and the distance between nodes and base station. At the same time, the optimal nodes were selected as the cluster head and the cluster head has transmitted the data to base station in a single or more jumps through searching right path in the improved algorithm. The simulation results show that th e nodes energy consumption of network was reduced significantly and the network life cycle was extended.

摘要：
Currently, most sentiment analysis of microblog has been focused on coarse-grained sentiment analysis, but fine-grained sentiment is better for reflecting the opinion of the public when they are facing the social focus. Therefore, a hybrid strategy which is a combination of Naïve Bayesian and two-layer CRFs is put forward, which has been applied to the fine-grained sentiment analysis of Chinese microblog. First, microblog is classified into two types: sentiment and non-sentiment by using Naïve Bayesian classification algorithm. And then the first-layer CRFs model is built for the topic emotional sentence. Finally CRFs algorithm is used again to do multi-classification to assign a specific sentiment category. Experimental results show that a good result in sentiment identification based on the combination of Naïve Bayesian and CRFs, and also show the advantage of the combination of Naïve Bayesian and CRFs interrelated with emotional sentence extraction based on CRFs.

摘要：
Using the first-principles calculations based on density functional theory, we investigated the electronic properties of armchair graphene nanoribbons (AGNRs) with boron nitrogen (BN) doping. The B and N impurities can adjust the electronic properties of the AGNRs, whose features strongly depend on the impurity types and the ribbon width of the AGNRs. Interestingly, with the increase of the ribbon width, the energy gap of the AGNRs with B/N pair doping is oscillatory. The AGNRs with B or N doping show metallic behavior, and the localized unsaturated electronic states on the edge atoms lead to magnetism. These unconventional doping effects could be used to design semiconductor electronic devices. (C) 2014 Elsevier Ltd. All rights reserved.

摘要：
The traveling salesman problem（ TSP） is a well-known combinatorial optimization problem as well as an NP-complete problem. A dynamic multi-swarm particle swarm optimization and ant colony optimization（ DMPSO-ACO） was presented for TSP.The DMPSO-ACO combined the exploration capabilities of the dynamic multi-swarm particle swarm optimizer（ DMPSO） and the stochastic exploitation of the ant colony optimization（ ACO） for solving the traveling salesman problem. In the proposed hybrid algorithm,firstly,the dynamic swarms,rapidity of the PSO was used to obtain a series of sub-optimal solutions through certain iterative times for adjusting the initial allocation of pheromone in ACO. Secondly,the positive feedback and high accuracy of the ACO were employed to solving whole problem. Finally,to verify the effectiveness and efficiency of the proposed hybrid algorithm,various scale benchmark problems were tested to demonstrate the potential of the proposed DMPSO-ACO algorithm. The results show that DMPSO-ACO is better in the search precision,convergence property and has strong ability to escape from the local sub-optima when compared with several other peer algorithms.

摘要：
To further explore the up-to techniques for bisimulation in the coalgebra setting, we investigate a special kind of functor, i.e., product functor in this paper. Specifically, when F is the product of n sub-functors, in order to generate an up-to proof for bisimulation, it is sufficient to find n functions, where each one is consistent with its corresponding sub-functor, as well as weakly consistent with other sub-functors. The array formed by the n functions is called jointly consistent with F. We also give the analogue of jointly consistent function in traditional set theory. As for application, examples are given both coalgebraically and set-theoretically.

摘要：
Many Studies has carried on the technology of detecting invariants, for example, Daikon can detect most of invariant by presetting some types of them. But unary polynomial inequality likely invariants are rarely discovered by traditional tools. An effective method to detect unary polynomial inequality likely invariant was proposed in this paper. Through analyzing the property of value ranges of unary polynomial inequality likely invariants, the algorithm set the threshold value and calculates neighbor distances to determine the form of invariants. Finally, experimental results are given to demonstrate the effectiveness of this method.

摘要：
Data de-duplication divides backup stream into chunks and eliminates duplicate chunks across the entire system, thus remarkably reduces the storage and bandwidth requirement for backups. However, this technique also introduced many new problems among which the performance problem has been resolved by many of the existing solutions, while the logical data deletion problem is not well studied till now. This paper studied the logical data deletion mechanism in de-duplication backup systems, analyzed the memory overhead of the Bloom filter, which supports both high performance de-duplication and logical data deletion, and proposed a lazy deletion method to minimize the influence of logical data deletion on de-duplication performance.
摘要：
Using the genre perspective, we studied the electronic communication of knowledge users collaborating on a movie community and found that their work and interactions were mediated by the use of genres. Drawing on these findings, we develop the concept of genre repertoire to designate the set of genres enacted by groups, organizations, or communities to accomplish their work. Automatic discourse classification according to genre in social information sharing, transfer and knowledge communication provides a higher level of service quality. By investigating user behavior in movie community, the relationship between intertextuality of discourse genre and user behavior was studied. We denoted genre by using vector, and discourse genre intertextuality intensity is measured with vector distance. And for those discourse which genre is unknown, genre intertextuality is calculated using user behavior. The results show that user various behaviors stickiness in movie community and discourse genre intertextuality intensity have potential common features.
