Wenjun Zhang, Jincai Lin, Ning Jia
A dual-wavelength erbium-doped fiber laser (DW-EDFL) which can output double wavelengths of 1530nm, and 1550nm is proposed in this paper. The optimal condition for optimum output power of two wavelengths is extracted and demonstrated. When the length of EDFL is 4.13m the output power of the two wavelengths can reach 2mW. Additionally, two variable optical attenuators (VOA) are used to balance gain and loss of two signal lights in the ring resonator.

An improved link prediction algorithm based on common neighbors index with community membership information 一种改进的基于社区成员信息的共同邻居索引的链路预测算法
Zhao Yang, Rongjing Hu, Ruisheng Zhang
human life is more and more dependent on the safety, reliability and effective operation of a variety of complex networks; however, most of networks are sparse, which means the network data is incomplete. To solve the problem, various link prediction methods have been proposed to find missing links in given networks. Among these methods, similarity-based methods are effective, however, still imperfect. In order to improve the predicting results, we combined local and global information of the network and then proposed a method based on one of similarity-based methods with community information. Experiments results show that the inclusion of community information improves the accuracy of results of predicting missing links.
人类的生活越来越依赖于各种复杂网络的安全、可靠和有效运行;然而,大多数网络是稀疏的,这意味着网络数据是不完整的。为了解决这个问题,人们提出了各种链路预测方法来发现给定网络中的缺失链路。在这些方法中,基于相似度的方法是有效的,但仍然不完善。为了提高预测结果,我们将网络的局部和全局信息结合起来,提出了一种基于相似度的方法与社区信息相结合的预测方法。实验结果表明,社区信息的加入提高了缺失链接预测结果的准确性。

Optimized design of hierarchical substation monitoring information based on MapReduce technology 基于MapReduce技术的分层变电站监控信息优化设计
Shaoxiao Han, Xianghua Pan, Chen Li, Shengyuan Gao
With the rapid development of regional economy in Shandong Province, the demand of electric power increases rapidly. So, the development of the substation construction and its status information detection system has led to the massive power equipment status information data, which needs to be sorted out and standardized work. In this paper, the MapReduce technology is used for the degradation processing of monitor information according to the station control layer, bay layer and process layer; meanwhile, the voltage level of substation is used as the breakthrough point, and the similar or same monitoring information is combined and processed. Compared with the traditional method of processing power equipment monitoring information on cluster computer platform, the MapReduce technique can be verified to achieve monitoring data simplification, recursive and transplantation in substation monitoring and control information cloud platform. It could improve work efficiency in the three aspects of utility value, completion time and load balance.
随着山东省区域经济的快速发展,电力需求迅速增长。因此,变电站建设及其状态信息检测系统的发展产生了海量的电力设备状态信息数据,需要对这些数据进行整理和规范工作。本文采用MapReduce技术,按站控层、站仓层、过程层对监测信息进行降级处理;同时以变电站的电压等级为切入点,将相似或相同的监控信息进行组合处理。与传统的在集群计算机平台上处理电力设备监控信息的方法相比,可以验证MapReduce技术在变电站监控信息云平台上实现监控数据的简化、递归和移植。它可以从效用价值、完成时间和负载均衡三个方面提高工作效率。

Z. Chunsheng, Li Yan
Visual data mining techniques can display the process of data mining and results to the user graphically, which makes the user more perceptual and easy to understand the meaning of the mining process and its results and moreover it is very important in data mining. However, most of the visual data mining now is progressed with the result of visualization. At the same time, it is not suitable for the graphical display to the visualization processing of the association rule. In view of the above shortcomings, in this paper, the whole mining process of Apriori association rule is visually conducted under the natural language by the way of the natural language processing method, including data preprocessing, mining process and the visualization display of mining results which provides an integrate set of schemes for the user with characteristics of being more perceptual and more easy to understand.
可视化数据挖掘技术能够将数据挖掘的过程和结果以图形化的方式展示给用户,使用户更容易理解挖掘过程和结果的含义,在数据挖掘中具有十分重要的意义。然而,目前大多数可视化数据挖掘都是在可视化的基础上进行的。同时,对关联规则的可视化处理不适合图形化显示。针对上述不足,本文采用自然语言处理方法,将Apriori关联规则的整个挖掘过程可视化地在自然语言下进行,包括数据预处理、挖掘过程和挖掘结果的可视化显示,为用户提供了一套完整的方案,具有更感性、更易于理解的特点。

Toward comprehensible software defect prediction models using fuzzy logic 利用模糊逻辑建立可理解的软件缺陷预测模型
Hamdi A. Al-Jamimi
Software defect prediction is a discipline that predicts the defects proneness of future modules. Software metrics are used for this kind of predication. However, the predication metrics are associated with uncertainty, thus the metrics need to be expressed in linguistic terms to overcome ambiguity and uncertainty. Two types of knowledge are utilized as input to the prediction models: software metrics and expert's opinions. This paper proposes a framework for developing fuzzy logic-based software predication model using different set of software metrics. It aims to provide a generic set of metrics to be used for software defects prediction. The performance of the proposed Fuzzy-based models has been validated using real software projects data where Takagi-Sugeno fuzzy inference engine is used to predict software defects. Validation results are satisfactory.
软件缺陷预测是一门预测未来模块缺陷倾向的学科。软件度量用于这类预测。然而,预测度量与不确定性相关联,因此需要用语言术语表示度量以克服歧义和不确定性。两种类型的知识被用作预测模型的输入:软件度量和专家的意见。本文提出了一种基于模糊逻辑的软件预测模型的框架,该模型采用了不同的软件度量集。它旨在为软件缺陷预测提供一套通用的度量标准。利用Takagi-Sugeno模糊推理引擎对软件缺陷进行预测的实际软件项目数据验证了所提出的模糊模型的性能。验证结果令人满意。

A consistency verification method with semantics for component-based software designs 基于组件的软件设计的语义一致性验证方法
Xue Li, Jiagang Zhu
The existing consistency checking methods for component-based software designs are unable to check the semantics consistency and the interface consistency because the protocols themselves do not contain these information. Li order to enable the consistency checking method to check semantics consistency and interface consistency besides protocol consistency, we propose a consistency checking method by introducing the idea of method semantics into scenario-based specifications. The semantic extended interface automata (SIA) model is utilized to describe the semantics, interface and protocol information of components. The scenario-based specifications are specified by interaction overview diagrams with semantic constrains. Then according to the analysis of the behaviors of SIA model and interaction overview diagrams with semantic constrains, we developed an algorithm to check the consistency between component-based designs and the scenario-based semantic specifications. Our algorithm not only can check the protocol consistency but also the method semantic consistency which includes the type and semantics of methods.
现有的基于组件的软件设计一致性检查方法由于协议本身不包含语义一致性和接口一致性信息,无法进行一致性检查。为了使一致性检查方法能够在检查协议一致性的同时检查语义一致性和接口一致性,我们将方法语义的思想引入到基于场景的规范中,提出了一种一致性检查方法。采用语义扩展接口自动机(SIA)模型描述组件的语义、接口和协议信息。基于场景的规范由带有语义约束的交互概览图指定。然后,在分析SIA模型行为和带有语义约束的交互概览图的基础上,提出了一种基于组件的设计与基于场景的语义规范一致性检验算法。该算法不仅可以检查协议的一致性,还可以检查方法的语义一致性,包括方法的类型和语义。

Implementation of partitional clustering on ILPD dataset to predict liver disorders 基于ILPD数据集的分区聚类预测肝脏疾病的实现
M. Babu, M. Ramjee, Somesh Katta, S. K.
Cluster Analysis methods are very important, popular data summarization techniques applied in diverse environments. These techniques retrieve the hidden patterns in large datasets in the form of characterized patterns which can be interpreted further in different contexts. Widespread use of medical information systems and explosive growth of medical databases require traditional manual data analysis coupled with efficient computer assisted analysis. Medical Diagnosis is a difficult process which needs proficiency as well as experience to cope with a disease. Data segmentation is an application in medical domain used to analyze patient records, disease trends and health care resource utilization, which in turn assist a physician in Medical Diagnosis. In the present paper a technique based on classification techniques is proposed to predict liver disorders accurately. The main objective is to examine whether the proposed method can obtain better prediction accuracy to traditional classification algorithms. The classification results using the proposed method are found to be very promising and accurate.
聚类分析方法是一种重要的、流行的数据汇总技术,应用于各种环境中。这些技术以特征模式的形式检索大型数据集中的隐藏模式,这些特征模式可以在不同的上下文中进一步解释。医疗信息系统的广泛使用和医疗数据库的爆炸性增长需要传统的人工数据分析与高效的计算机辅助分析相结合。医学诊断是一个困难的过程,既需要熟练程度,又需要经验来应对疾病。数据分割是医学领域的一种应用,用于分析患者记录、疾病趋势和医疗资源利用情况,从而辅助医生进行医疗诊断。本文提出了一种基于分类技术的准确预测肝脏疾病的方法。主要目的是检验该方法是否能获得比传统分类算法更好的预测精度。结果表明,该方法具有较高的分类精度和较好的应用前景。

Capture global Kad lookup traffic 捕获全局Kad查找流量
Zhibo Liu, Qiang Li
Kad is the most popular P2P file sharing system. It is very difficult to capture all the users' lookup traffic because of its full distributed feature. Previous work could only monitors a subset of the lookup traffic. In this paper, we propose a lightweight method to monitor the global lookup traffic by inserting two ‘nearest neighbor’ peers into the peer at the last iteration of Kad lookup path. Since one of the inserted peer is closer than the last peer definitely, the user's search request would be redirected to the trap node. The experiment performed on eMule0.50a shows that this approach could capture most lookup traffic.
Kad是最流行的P2P文件共享系统。由于其完整的分布式特性,很难捕获所有用户的查找流量。以前的工作只能监视查找流量的一个子集。在本文中,我们提出了一种轻量级的方法,通过在Kad查找路径的最后一次迭代时向对等体中插入两个“最近邻”对等体来监控全局查找流量。由于插入的对等体中肯定有一个比最后一个更近,因此用户的搜索请求将被重定向到trap节点。在eMule0.50a上进行的实验表明,这种方法可以捕获大多数查找流量。

Design and implementation of recommender system based on Hadoop 基于Hadoop的推荐系统的设计与实现
Qing Wang
Recommender system is to establish the relationship between the user and the information products, to use the existing selection habits and the similarity of each user's potential interest in the object, and then personalized recommendation. It is one of the effective ways to solve the information overload in the Internet age. But in practical application, because of the large number of products and the number of users, the traditional recommendation system is usually run on the single machine, which has been far from meeting the needs of such big data. In this paper, we design and implement a network recommendation algorithm based on Hadoop platform, which is based on the theory of Hadoop and Map/Reduce programming.
推荐系统就是建立用户与信息产品之间的关系,利用现有的选择习惯和每个用户潜在兴趣对象的相似性,然后进行个性化推荐。它是解决网络时代信息超载的有效途径之一。但在实际应用中,由于产品数量多,用户数量多,传统的推荐系统通常在单机上运行,已经远远不能满足这种大数据的需求。本文基于Hadoop和Map/Reduce编程的理论,设计并实现了一种基于Hadoop平台的网络推荐算法。
