The research and development results of agent technology are awaited as the software solution with autonomy and social ability, which can provide the way to realize social activities on the Internet. However, the current status of the agent research is that research is for a specific application domain and is not so much generalized, and it is hard to apply the framework of the existing research to other fields. Moreover, it is thought that practical usage of agent is in immature state that there are few practical application examples and the system development methodology is not sufficient. In this research, the problem solving system by the multi-agents is first shown as an application development framework by the agents. Then, we present usage of templates of the agent model and the task model as the development support technique. And the evaluation according to an application construction experiment in the field of remote product management is discussed.

Artificial neural networks are intended to be used in emerging technologies as information processing systems because their biological equivalents seem to be tolerant to internal failures of computational elements. In this paper, we introduce a measurement which can identify significant neurons of the local cluster neural network and can be used to increase the fault tolerance of this network architecture. Furthermore, it show that this technique can control the network's complexity. Moreover, by this quality different parameter sets of the network and training techniques can be judged with respect to their fault tolerant properties.
Most of the current trust models in peer-to-peer (P2P) systems are identity based, which means that in order for one peer to trust another, it needs to know the other peer's identity. Hence, there exists an inhere...

In this paper, combined with Tatsuoka 's Rule Space Model and the Attribute hierarchy Method (AHM), Formal Concept Analysis (FCA) is firstly applied into Computerized Adaptive Testing (CAT). Based on FCA, an initiatory and systemic CAT with cognitive diagnosis (CD) is designed, which diagnoses examinees real time. The result of Monte Carlo study shows that examinees ' knowledge states are well diagnosed and the precision in examinees ' abilities estimation is satisfied.

The information measurement of the NAR (network access requester) is the key element for trusted network access. The only issues TNC (trusted network connection) proposed the conception of integrity measurement and pointed out that only if the measurements passed can the NAS ((network access server) let the endpoint enter. But no concrete techniques are expatiated in TNC, and the related specification IMM (integrity measurement model) is too complex to implement. Virtually, the measurement cannot be localized to the integrity. In this paper, a new information measurement architecture is proposed, in which not only the integrity information of the platform, but also the identity of user and platform, and the information of system availability are considered. The related techniques (information collection and verification etc.) are illustrated, and the trust chain transfer is analyzed at the end.

AXML (active XML) is a framework for peer-to-peer data integration from XML sources. In AXML documents data can be presented extensionally or intentionally by including calls to local or remote Web services. In complex AXML-based systems data retrieval can be inefficient. In the paper we propose a caching mechanism for systems based on active XML. We show how it can influence network communication and data integration processes.

In our work, we mainly use a lattice Boltzmann method (LBM) to simulate the underlying dynamics of miscible mixtures in binary fluid simulation called TFLBM. However, it suffers from the limitation of only resolving mixture flows with low Reynolds number, and it would blow up when the Reynolds number gets higher. In order to resolve such mixture flows with higher Reynolds number, by further investigation, we proposed to use a subgrid method to stabilize the computation of two fluid mixtures. The idea of the subgrid method is to split the actual velocity field into large-scale (resolved) and small-scale (unresolved) components. The effect of the unresolved motion on the resolved one is included by introducing a so-called eddy viscosity, and the method is also referred to as large eddy simulation (LES).
