摘要:
In response to the Internet users are about the same theme of mass information effectively filter and extraction, this paper proposes a document based on particle size of the news MGNF fusion algorithm, particle size document means that face now the newest microblog and short documents and traditional news dissemination documents, both document length although different, but as based on the calculation of grassroots journalism and communication mode. Through mining the different particle size of the document different views, we can find out the potential to be found for the information. The experimental results verify the effectiveness of the proposed algorithm.
摘要:
This paper presents an electrocardiographic signal classification method. This method first uses a revised locally linear embedding (LLE) algorithm to perform dimension reduction to the Electrocardiography (ECG) data. This manifold distance measurement-based LLE was proposed to solve the defect of conventional LLE that, due to the use of Euclidean distance, it could not properly measure the distance between high-dimensional samples. Using this revised LLE algorithm for the dimension reduction of data, more original data information could be retained, and the features of high-dimensional ECG data could be more effectively extracted, thereby improving the classification accuracy. The method then adopts kernel-based fuzzy C-means clustering algorithm to perform ECG signal classification. Classification tests on four common types of ECG signals-from the MIT-BIN database showed that the proposed method reached an overall accuracy of 99%.

摘要:
In urban transit network inquiry system, the optimal scheme of bus line having excessive transfers requires us to consider limiting the number of transfers when to compute the optimal scheme of bus line [1], which can come down to shortest path problem limiting the number of intermediate vertex. And support system of QoS (Quality-of-Service) is playing a more and more important role in communication network. QoS routing problem [2] is to choose transmission path meeting the requirements of QoS service to hop counts, bandwidth, latency, packet loss rate etc. and ensuring effective use of global network resources, which can come down to multi-constrained shortest path problem limiting the number of intermediate vertex. Shortest path problem limiting the number of intermediate vertex is shortest path problem with k-intermediate vertex constraints.
摘要:
A virtual machine placement strategy based on the trade-off between energy consumption and SLA is presented. Aiming at dynamical changes of workload requirements, a self-adaptive placement strategy RLWR based on robust local weight regression is presented, which could decide the overload time of hosts dynamically. After detecting overloaded hosts, one virtual machine migration selection algorithm MNM is proposed. The MNM's objective is to get minimal migration number. The migrated virtual machines are deployed using bin-packing algorithm PBFDH. The experimental results show that our algorithm has obvious advantages than other algorithms.
摘要:
Offline storage technology has many uses in the Web application and it can store the user status, cache data, temporary data, and persistent data and so on. In this paper several typical web client storage technologies are discussed and it includes the IE browser's unique storage technology UserData, localStorage and sessionStorage of HTML5, Web SQL Databases, Indexed Database, as well as classic storage technology Cookie and so on. Their concrete using methods are explained and their individual strengths and differences are compared. Their respective applications occasions and some issues that need attention are discussed. The general cross-browser offline storage method is presented and it can use the same application programming interface to complete different browser offline storage technologies.
摘要:
Web services are the new paradigm for distributed computing. A critical factor to the overall utility of Web services is a scalable, flexible and robust discovery mechanism. Currently Web Service systems, which publish WSDL-described Web Services in UDDI, cannot support automatic Web Service publication, discovery and execution. Traditional centralized indexing scheme can't scale well with a large distributed system. In this paper, we present a service discovery model for building dynamic, scalable, decentralized registries with flexible search capabilities, to support Web service discovery. In our work, we focus on a fully distributed architecture motivated by recent advances in a two-layer P2P network topology without a need for centralized service registries. Furthermore, the OWL-S ontology is used to add semantics to the Web Service descriptions and then register them on a specific registries peer in the P2P environment according to the service's domain ontology. The experiments show that the discovery model has good scalability and the semantic annotation can notably improve discovery exactness. The improved algorithms can discover the most potential service against request.
摘要:
丢包现象严重影响VoIP的通话语音质量。WSOLA(Waveform Similarity Based Overlap-Add)算法是一种基于接收端的丢包隐藏方法,可以较好地提高语音质量。在介绍WSOLA算法原理的基础上,针对该算法中计算互相关系数所需计算量较大,会增加过多计算延时的问题,提出一种互相关系数计算的改进方法。最后通过仿真对重建语音信号质量进行了对比。
