Failure cases are very important for failure analysis. So how to deduce the failure mode of a new failure case based on existed failure cases will be discussed in this file. Firstly, according to the collection of large accident case, summarized how to deduce the failure features and failure information of each failure modes may have. Then identify the possibilities of the new failure case belong...
This paper is devoted to robust adaptive sliding mode control for a class of nonlinear systems in the Takagi-Sugeno forms with mismatched parametric uncertainties. Sufficient conditions for the existence of linear sliding surfaces are given in terms of linear matrix inequalities, by which the corresponding adaptive reaching motion controller is also designed. Simulation studies show the effectiveness...
The problem of delay-dependent energy-to-peak filter design for a class of stochastic time-delay systems is investigated in this paper. Attention is focused on the design of full-order and reduced-order filters to guarantee a prescribed energy-to-peak performance for the filtering error system. The improvement lies in that the constructed Lyapunov-Krasovskii functional, based on the delay partitioning...
Personalized e-learning is a hot research topic. It can obviously improve the learning efficiency. A perfect e-learning system can recommend right learning content for right learner at right time. In order to find profit contents for different users, a network which describes the relationships among learners is constructed first. Then, the learners owning similar learning interests are found by community...
Materials database is widely used in materials science nowadays. It can be used to manage the lifecycle of materials, to accomplish the material data sharing, and to save time and cost spending on experiments for users. However, since properties of materials are often affected by the constructed structures and their service environments, it is difficult to describe those properties properly by database...
Verification and validation (V&V) are the primary means to assess accuracy and reliability of computational simulations. V&V methods and procedures have fundamentally improved the credibility of simulations in several high-consequence application military areas, such as, safety of nuclear weapons, and the trial of some missiles. In this paper we discuss how to quantify the V&V process...
At present, most of the remote teaching systems concentrate in C/S distributed systems, which have brought on problems caused by diversity, heterogeneity and dynamicity of computing resources. Nowadays, the self-organization service network has appeared, which is a new network architecture that is service-oriented and supports the dynamic publication, inquiry and exit of services, solving problems...
Introducing e-learning can obviously improve the learning efficiency. How to introduce profit contents to users is the key issue. An available way is to introduce the same contents to the users with similar interest and study ability. Community detection can divide users into several subgroups with similar interest and study ability. An e-learning system can determine the introducing contents for...
Appropriate locations for distribution centers benefit both distribution centers and their clients. Many location models of distribution centers base on the assumption that the companies that the distribution center serves are known. Few literatures touch on the issue that if the right companies have been found as the service objects for the distribution center. This paper believes the better way...
Web page is the main contents on the World Wide Web. Similarity of Web pages is very helpful for Web content analysis. Text similarity, usually called similarity computation, has been investigated for decades in artificial intelligence area. Some similarity computation methods have been used to compare Web pages. However, text based similarity computation methods are incompetent for Web page comparing,...
Web topic is the theme indicated by Web pages. Some methods have been proposed to represent Web topic based on text mining. However, these methods canpsilat denote multimedia contents on Web page, such as images, audios, videos and so on. Consequently, text-based methods can't represent Web topic exactly because most Web pages consist of many multimedia contents. This paper proposes a new approach,...
Because of the randomness of biometric features, traditional methods cannot perform well in the encryption of fingerprint template. The Fuzzy Vault construct is a biometric cryptosystem which can bind the fingerprint features with the secret key, and give reliable protection to both of them. The performance of Fuzzy Vault is highly affected by the alignment of fingerprints in the encryption field...
Web topic indicates the topic from Web pages on the Internet. Traditional methods to describe a Web topic come from text mining. However, Web page consists of not only text but also multimedia contents, such as image, audio, video and so on. The multimedia contents of Web topic can't be denoted by text-based representation methods. This paper proposes a new approach, named multi-layer representation...
