A multi-agent architecture for electronic payment
The Internet has brought about innumerable changes to the way enterprises do business. An essential problem to be solved before the widespread commercial use of the Internet is to provide a trustworthy solution for electronic payment. We propose a multi-agent mediated electronic payment architecture in this paper. It is aimed at providing an agent-based approach to accommodate multiple e-payment schemes. Through a layered design of the payment structure and a well-defined uniform payment interface, the architecture shows good scalability. When a new e-payment scheme or implementation is available, it can be plugged into the framework easily. In addition, we construct a framework allowing multiple agents to work cooperatively to realize automation of electronic payment. A prototype has been built to illustrate the functionality of this design. Finally we discuss the security issues

A modularized electronic payment system for agent-based e-commerce
With the explosive growth of the Internet, electronic-commerce (e-commerce) is an increasingly important segment of commercial activities on the web. The Secure Agent Fabrication, Evolution & Roaming (SAFER) architecture was proposed to further facilitate e-commerce using agent technology. In this paper, the electronic payment aspect of SAFER will be explored. The Secure Electronic Transaction (SET) protocol and E-Cash were selected as the bases for the electronic payment system implementation. The various modules of the payment system and how they interface with each other are shown. An extensible implementation done using JavaTM will also be elaborated. This application incorporates agent roaming functionality and the ability to conduct e-commerce transactions and carry out intelligent e-payment procedures
Analysis of the strong vertices of and in QCD sum rules
The strong coupling constant is an important parameter which can help us to
understand the strong decay behaviors of baryons. In our previous work, we have
analyzed strong vertices , ,
, in QCD sum rules. Following these work, we
further analyze the strong vertices and
using the three-point QCD sum rules under Dirac structures
and . In this
work, we first calculate strong form factors considering contributions of the
perturbative part and the condensate terms ,
and . Then, these form factors are used to fit into analytical functions.
According to these functions, we finally determine the values of the strong
coupling constants for these two vertices and
