Spectrum database plays an increasingly important role in spectrum measurements and monitoring, which lays foundations for accurate and real-time spectrum sensing in future cognitive radio networks. A successful identification of the channel propagation model is of great importance to construct spectrum database so as to give an accurate picture of spectrum use in real-world environments. In this...
Developers use many software applications to process large amounts of diverse information in their daily work. The information is usually meaningful beyond the context of an application that manages it. However, as different applications function independently, developers have to manually track, correlate and re-find cross-cutting information across separate applications. We refer to this difficulty...
Traditional financial trading systems were developed in database-based standalone model years ago. Given that there exist some evident drawbacks like high latency and low availability in such architecture, it is imperative to design a new model which can meet the requirements of time-sensitive financial transactions. Therefore, in this paper we design and implement a state-replication based matching...
Under the real information environment, because the time or department to develop information system is different, there are always many heterogeneous information systems run at the different software and hardware platforms which are executed simultaneously. The separate and closed data source in the system makes data hard to be communicated, shared and fused among the systems. Data integration using...
Software internationalization and localization are important steps in distributing and deploying software to different regions of the world. Internationalization refers to the process of reengineering a system such that it could support various languages and regions without further modification. Localization refers to the process of adapting an internationalized software for a specific language or...
Through the analysis of some security vulnerabilities of WiMAX network and according to the characteristics of the WiMAX network and the research status of intrusion detection, this paper designs and realizes an intrusion detection system based on WiMAX which has the following two features contrast with the existing methods: (1) the full consideration of the vulnerabilities, characteristics and performance...
A method is proposed to detect and eliminate the synchronous ECG artifacts in the EEG Signals based on the matching pursuit algorithm, which doesn't require the additional synchronous ECG channel or multichannel signals. By using the mixed over-complete dictionary, the EEG signals based on the matching pursuit algorithm are decomposed into atoms. The atoms that have the similar morphological characteristics...
Video annotation is very important for video management, such as video retrieval. Despite continuous efforts in inventing new annotation algorithms, the annotation performance is usually unsatisfactory, and the annotation vocabulary is still limited due to the use of a small scale training set. In this paper, a novel video annotation framework based on the video object is presented, named object-based...
This paper introduced and described the status quo and goal of current Chinese colleges and universities computer assistant teaching systems from many aspects, such as explore the background, design goal, information sharing, design features, technical characteristics and environment.
This paper firstly inquired the categories of knowledge on dam safety monitoring expert system and the knowledge acquisition process. Secondly, it not only analyzed knowledge representation about dam safety monitoring expert system, that is, factual knowledge, rule knowledge and procedure knowledge, but also established a simple knowledge base based on relational database for dam safety monitoring...
A concept of semantic web service discovery search model is proposed. The definition, the semantic web service discovery search model (SWSDSM) unified with the semantic and the search engine technology, is proposed after the existing Web service discovery technology studied systematically and thoroughly. This model might search for and fuse the information in the UDDI registries, then provide for...
Software testing is becoming more and more important as it is a widely used activity to ensure software quality. Testing is now an essential phase in software development life cycle. Test execution becomes an activity in the critical path of project development. In this case, a good test execution effort estimation approach can benefit both tester managers and software projects.This paper proposes...
