摘要：
Deep learning has shown its effectiveness in many tasks such as text classification and computer vision. Most text classification tasks are concentrated in the use of convolution neural network and recurrent neural network to obtain text feature representation. In some researches, Attention mechanism is usually adopted to improve classification accuracy. According to the target of task 6 in NLP&CC2018, a hybrid deep learning model which combined BiGRU, CNN and Attention mechanism was proposed to improve text classification. The experimental results show that the Fl-score of the proposed model successfully excels the task's baseline model. Besides, this hybrid Deep Learning model gets higher Precision, Recall and Fl-score comparing with some other popular Deep Learning models, and the improvement of on Fl-score is 5.4% than the single CNN model.

摘要：
This paper presents a new method to solve the crop- invariant problem of an invariant wavelet, RSTXIW, which is a rotation- and scaling- and translation- invariant. Based on the feature points and second moments of the signal and based on a scale function of Daubiechies wavelet, we renormalize a signal in the function space. By using the feature points to divide the signal into several parts and by applying cluster analysis, we can correctly calculate the whole second-order moments of the cropped signal. Then we can obtain the crop- invariance of the renormalized signal, tested by some experiments. (C) 2011 Published by Elsevier Ltd.
摘要：
we propose a distributed wavelet-based algorithm which can transform irregularly sample data using haar wavelet-based compression solutions in this paper. We consider the characteristics and location information of nodes in sensor networks, a new distributed data aggregation mode based on "area" is used firstly. On the basis of these new models, a novel wavelet-based irregularly sample data compression and data transform model DDCM is proposed for sensor networks. Theoretical analyses and simulation results show that, the above new methods have the good ability of approximation, and can compress the data efficiently and can reduce the amount of data greatly, So, it can prolong the lifetime of the whole network to a greater degree.

摘要：
Program analysis plays an important role in software development and maintenance. With this method, characteristics of every variable in program can be analyzed. During the period of program analyzing, computing the program slicing by the method of constructing system dependence graph is an efficient way but the work of constructing the system dependence graph is very complicated which often leads to many wrong results. So the algorithm of hierarchy slice is used in this paper. Using the precise results, the whole program can be analyzed and the dependence relation in the program can be discovered quickly.
摘要：
It has long been known that there are software applications for which it is difficult to detect subtle errors, faults, defects, or anomalies because there is no reliable "test oracle" to indicate what the correct output should be for arbitrary input. The absence of a test oracle clearly presents a challenge in testing the software applications of scientific computing from the domain of nuclear power plant. Metamorphic testing has been shown to be a simple yet effective technique in addressing the quality assurance of these "non-testable programs." In this paper, we introduce Metamorphic testing method to address the oracle problem as mentioned above. We identify a metamorphic relation for a real-world scientific computing programs which do not have test oracles, and demonstrate the effectiveness of metamorphic testing in identifying the error.

摘要：
In view of the characteristics of the physical code Nestor the focus is on the correctness of calculation for which the test adequacy criterion has been established. This is based on structural coverage and the input domain. According to such test adequacy criterion, testing strategies have been applied on the entire testing process. They consist of unit static, unit dynamic, integration, system and regression test strategy. Each strategy is composed of test target, test range, technology and method, entry criterion, completion criterion, test focus and priority. After compared with 11 basic benchmarks from nuclear power plants and calculation result of benchmark programs, the ELEMENT program result is correct and credible; the relative error of result is less than three percent. The ELEMENT testing is adequacy. Its test cases covers fuel grid element types, fuel types, non-combustible grid element types, and control rod computational models. Furthermore, it puts forward a research direction in the future.

Complex networks;Routing strategy;Effective path;Local visibility and Detecting communities
摘要：
A routing strategy using nodes' effective path and dynamic information weight distribution was proposed, which based on the improved efficient path routing strategy in complex network. The strategy's weight factor was optimized by the new strategy, Considering the insufficient of local routing strategies in global performance and the community division technology in complex network, a kind of local visibility routing strategy according to the thought of community division was presented. On the condition of community division of the Bgll condensation algorithm, the topology structure information of neighbor nodes and all the community nodes were only stored in each node's routing list in the new strategy. When node transaction in community, global routing strategy was adopted and when between communities, minimum load strategy will be used. The simulation results indicate that in the different connection density networks, the performance of the new strategy achieves the best when community division's degree of modularization is the highest. Contrasted to other local routing strategy, the optimized strategy holds incomparable superiority on throughput, transmission delay and the packet loss.

摘要：
Distributed storage systems have the advantages of self-organizing, scalability, robust and fault-tolerant, which provide fundamental support for mission-critical applications. Unfortunately, there still exist some problems in real network conditions, especially, when considering asynchronous distributed environments, where messages may be delayed indefinitely and nodes may fail. So, failure detector is one of basic components to build a reliable distributed storage system. Considering the highly dynamic characteristics of distributed system, a novel self-regulatory failure detection algorithm (SFDA), which can combine heartbeat strategy with unbiased grey prediction model, is designed to improve the failure detection quality of system (QoS) according to the application needs and network environment changes. The key goal of using correction value in SFDA is to provide adoptable and usable service in all kinds of applications. The results show that, failure detector based on SFDA is more effective and flexible than other failure detectors.
摘要：
Web document clustering is one of the most important research branches of Clustering Analyzing. The objective of web document clustering is to meet the need of retrieving web document efficiently from massive information in Internet. Recently social tagging is the important form of document organization in web 2.0, and the tagging as a document descriptor is used to improve the effectiveness of web searching. But a web document usually belongs to various category of tagging, which may lead to the difficulty of browsing web document based on single tagging. This paper explores the use of Formal Concept Analysis (FCA) as mathematical tool to analyze the social tagging of web document, and presents a model for web document clustering based on tagging semantic. Furthermore, taking community web site Douban as an example, the model is applied to allow users to tag and serendipitously browse web document using Formal Concept Analysis.

摘要：
This paper presents a new approach based on maximum entropy and maximum entropy Markov model for web information extraction. This approach is not only able to overcome the shortcoming of the less precision and recall of the hidden Markov model. In addition, this approach can make the most of various kinds of contextual information from web. The experiments are found that the hybrid approach has an average precision rate of 87.516% while the hidden Markov model trained by the Baum-Welch algorithm has an average precision rate of 68.630%. This implies that the hybrid approach is more optimized than the hidden Markov model trained by the Baum-Welch algorithm.
