Research on Emotional Vocabulary-Driven Personalized Music Retrieval
In this paper, aimed at emotional interactive needs in music retrieval, a new retrieval method, based on dynamic characteristics of fuzzy psychological and linguistic value computing of music emotion, is putting forward. And an improved interactive genetic algorithm is designed for the emotional retrieval goal. In order to reduce users' fatigue of retrieval process, choice operator for fine breed, crossover operator holding the dominant element of emotion vector, and self-genetic operation strategy are designed.

Fuzzy Classifier with Probabilistic IF-THEN Rules
The typical fuzzy classifier consists of rules each one describing one of the classes. This paper presents a new fuzzy classifier with probabilistic IF-THEN rules. A learning algorithm based on the gradient descent method is proposed to identify the probabilistic IF-THEN rules from the training data set. This new fuzzy classifier is finally applied to the well-known Wisconsin breast cancer classification problem, and a compact, interpretable and accurate probabilistic IF-THEN rule base is achieved.

Conditional Dempster-Shafer Theory for Uncertain Knowledge Updating
This paper presents a theory called conditional Dempster-Shafer theory (CDS) for uncertain knowledge updating. In this theory, a prioriknowledge about the value attained by an uncertain variable is modeled by a fuzzy measure and the evidence about the underlying uncertain variable is modeled by the Dempster-Shafer belief measure. Two operations in CDS are discussed in this paper, the conditioned combination rule and conditioning rule, which deal with evidence combining and knowledge updating, respectively. We show that conditioned combination rule and conditioning rule in CDS satisfy the property of Bayesian parallel combination.

A Novel Privacy and Copyright Protection Enforced Peer-to-Peer Network
Peer-to-peer (P2P) networks are widely used to share copyrighted contents and software illegally around the world. Development and applications of P2P technologies have faced strong legal and legislative challenges. A P2P network has to have built-in copyright protection to enable P2P technologies to advance on its own without court's and legislature's interference. In this paper, we propose a novel and practical P2P network with a strong privacy protection and reliable tracking mechanism to track the original uploader of any material in the P2P network. When a pirated material is found, its uploader is tracked down, and can be punished by revoking the access to the network, removing his or her uploaded materials, etc. The whole protection system is completely transparent to end users. The proposed scheme would effectively deter users from uploading illegally any copyrighted materials to and dramatically reduce copyrighted materials shared through our P2P network.

Validating a geographical image retrieval system
This paper summarizes a prototype geographical image retrieval system that demonstrates how to integrate image processing and information analysis techniques to support large-scale content-based image retrieval. By using an image as its interface, the prototype system addresses a troublesome aspect of traditional retrieval models, which require users to have complete knowledge of the low-level features of an image. In addition we describe an experiment to validate the performance of this image retrieval system against that of human subjects in an effort to address the scarcity of research evaluating performance of an algorithm against that of human beings. The results of the experiment indicate that the system could do as well as human subjects in accomplishing the tasks of similarity analysis and image categorization. We also found that under some circumstances texture features of an image are insufficient to represent a geographic image. We believe, however, that our image retrieval system provides a promising approach to integrating image processing techniques and information retrieval algorithms.

Research and Design of Multifunctional Intelligent Melted Iron Analyzer
A multifunctional intelligent melted iron analyzer is researched and designed. This device combined the function of thermal analysis for quality analysis of melted iron and ultrasonic measuring for nodularity. By thermal analysis, equation of linear regression wasused and the percentage composition of carbon, silicon and phosphorus etc. were obtained. In addition, thermal analysis was used to predict gray iron inoculation result, structure and performance. Therefore, ultrasonic measuring was adopted to be applied in this study to survey the nodularity of spheroidal graphite iron. In order to protect the analyzer far away from boiling melted iron, wireless temperature collection was adopted. The system is composed of PC104, single chip SPCE061 and other peripheral circuits. Designed temperature collection and ultrasonic measuring module, the software of data analysis and management is programmed by VB6.0 based on PC104 and windows operation system. After running for more than one year, the analyzer goes very well in the foundry.

A Note on the Cramer-Damgård Identification Scheme
In light of the recent work of Micali and Reyzin on showing the subtleties and complexities of the soundness notions of zero-knowledge (ZK) protocols when the verifier has his public-key, we re-investigate the Cramer-Damgard intended-verifier identification scheme and show two man-in-the-middle attacks in some reasonable settings: one simple replaying attack and one ingenious interleaving attack. Our attacks are independent of the underlying hardness assumptions assumed.

User-interface Design of Web Application Using Object-Z
A notation is presented for formally describing Web application’s design of a user-interface. The function of a Web application is given using formal specification language Object-Z and then some generic classes, relationships and system actions are defined to specify user-interface design. In user-interface design, UAN annotations are added to Object-Z notation. The extended Object-Z notation expresses the presentation relationship between the design and the specification. This formal specification and design is useful in documenting a user-interface design and enables the analysis of the usability and safety of a Web application. In particular, it can be used to generate test cases automatically. An example of student information management system is used to illustrate the notation. Task efficiency is analyzed with the example.
