摘要：
The optimal parameters of candidate measures established by importance sampling are usually obtained by minimizing the quadratic criterion. To begin with, in this paper a scheme is developed for finding the alternative measure that is optimal in the sense that the p-order relative moment is minimized. Secondly, a necessary and sufficient condition for asymptotic efficiency of the optimal change of drift is demonstrated. Lastly, the change of drift is selected through Robbins-Monro type algorithm. When pricing options via Monte Carlo simulations, several numerical examples contrasting different p values that illustrate the efficiency of the proposed method are also included, as well as an interpretation of their different performances in terms of strike prices.

摘要：
This paper presents a method of converting relational database into XML documents, that is de-normalization and synthesis. Both the principle and implementation of the method are discussed. This method involves three steps. Firstly, we revert the normal relation schema to original unnormal one without the functional dependency, transfer functional dependency, multivalued dependency and join dependency. These unnormal relation tables are called connection tables. Then the connection tables are changed to XML documents and XML tree. In the end, all those XML documents are merged. According to the principle, the method is implemented in the case of bank loan. In this example, the data demonstrate the validity and feasibility of the method.

Semantic grid, the cross field of semantic web and grid computing, has received significant attention recently. Our workgroup develops a resource management semantic grid—— RM-Grid to enhance information process accuracy and efficiency in semantic heterogeneity environment. This paper describes the architecture of RM-grid, mainly introduces the data translation service of RM-Grid. It puts forward an ontology based common semantic model and an XML based data model, presents the data translation algorithm between different data sources and an adapter framework for accessing distributed heterogeneous resources as well.

With the development of computer technology, PCI peripheral bus is the most popular bus in the Pentium computer because of its excellent performance. But PCI bus criterion is so complicated that it is difficult to do interface decode. PCI data and address time division multiplex and their operation is synchronized with 33MHZ bus clock. Firstly, this paper introduces PCI bus fundamental theory and interface implementation schemes simply. In allusion to PCI interface circuit implement's complication, the paper introduces AMCCS5933 interface chip scheme, and expatiates AMCCS5933 internal structure, working theory. data transfer mode, function characteristics, interface driver and its application in PCI card design with details.

摘要：
We introduce entropy in fuzzy sets theory into digital image segmentation. According to the fuzzy character plane, firstly we get the segmentation threshold when the fuzzy bandwidth is given based on the maximal entropy principle. Then we develop the traditional binary segmentation to multi-value fuzzy segmentation, make modification of the threshold based on the multi-value fuzzy segmentation. When the difference between the object and the background is great, take the image 'Cameraman' for example, this method can effectively extract the object; When the difference between the object and the background is not great, take the image 'Lena' for example, this method can show plenty of edge information.

Constructing an effective translation between different representations is the key point to overcome semantic heterogeneity in information integration systems. This paper puts forward an ontology based information representation architecture-SOSRA. It introduces a GAV (global as view) approach to solve the mapping between heterogeneous semi-structured data in the form of service, discusses the semantic representation algorithm and semantic mapping strategy emphatically. The implementation of SOSRA and its application to semantic integration system is given at the end of this paper to enhance information process accuracy and efficiency.

fuzzy set;sigma-entropy;the structure of entropy of fuzzy set
摘要：
Based on special additivity of sigma-entropy and proposition of monotone function, we study the structure of a-entropy of fuzzy set. At first, we describe the structure of a-entropy. Then, with this structure in place, we derive primary propositions of sigma-entropy, and a conclusion of the entropy under l(p)-distance, that is, this entropy of fuzzy set has sigma-additivity only if p equals 1.
摘要：
Outlier detection is a key element for intelligent financial surveillance systems which intend to identify fraud and money laundering by discovering unusual customer behaviour pattern. The detection procedures generally fall into two categories: comparing every transaction against its account history and further more, comparing against a peer group to determine if the behavior is unusual. The later approach shows particular merits in efficiently extracting suspicious transaction and reducing false positive rate. Peer group analysis concept is largely dependent on a cross-datasets outlier detection model. In this paper, we propose a new cross outlier detection model based on distance definition incorporated with the financial transaction data features. An approximation algorithm accompanied with the model is provided to optimize the computation of the deviation from tested data point to the reference dataset. An experiment based on real bank data blended with synthetic outlier cases shows promising results of our model in reducing false positive rate while enhancing the discriminative rate remarkably.
