Absolute exponential stability of a class of continuous-time recurrent neural networks

This paper presents a new result on absolute exponential stability (AEST) of a class of continuous-time recurrent neural networks with locally Lipschitz continuous and monotone nondecreasing activation functions. The additively diagonally stable connection weight matrices are proven to be able to guarantee AEST of the neural networks. The AEST result extends and improves the existing absolute stability and AEST ones in the literature.     

A linear matrix inequality (LMI) approach to robust H/sub 2/ sampled-data control for linear uncertain systems

In this paper, we consider the H/sub 2/ sampled-data control for uncertain linear systems by the impulse response interpretation of the H/sub 2/ norm. Two H/sub 2/ measures for sampled-data systems are considered. The robust optimal control procedures subject to these two H/sub 2/ criteria are proposed. The development is primarily concerned with a multirate treatment in which a periodic time-varying robust optimal control for uncertain linear systems is presented. To facilitate multirate control design, a new result of stability of hybrid system is established. Moreover, the single-rate case is also obtained as a special case. The sampling period is explicitly involved in the result which is superior to traditional methods. The solution procedures proposed in this paper are formulated as an optimization problem subject to linear matrix inequalities. Finally, we present a numerical example to demonstrate the proposed techniques.     

Trusted Agent-Mediated E-Commerce Transaction Services via Digital Certificate Management

Agent-mediated e-commerce (AMEC) transaction services will be a paradigm shift from the existing client–server e-commerce model. In order to fulfill the leverage of AMEC intermediary services with secure and trusted service capabilities, we propose an agent-oriented public key infrastructure (PKI) operating with a variety of digital certificates. Under this agent-oriented PKI, several trusted AMEC transaction service models will be demonstrated using human and agent certificates showing, delegation, and verification protocols. We establish human/agent authentication, authorization, delegation, access control, and trusted relationships before these trusted AMEC intermediary services can be realized. This paper shows that a trusted AMEC system can be implemented in the FIPA compliant multi-agent system.
