1. Examples and properties of Complex Adaptive Systems The most complex systems known to us, e.g., living systems, brains, ecologies and human societies, seem to share certain common properties. All these systems are highly nonequilibrium systems, exchanging energy/materials/information with their environment. Within a certain range of environments they are quite robust, and exhibit complex sta...

This paper addresses the problem of automatically recognizing linguistically significant nonmanual expressions in American Sign Language from video. We develop a fully automatic system that is able to track facial expressions and head movements, and detect and recognize facial events continuously from video. The main contributions of the proposed framework are the following: (1) We have built a...

This paper presents a institutional framework for the currency basket peg system. After the Asian currency crisis, the needs of seeking adaptive currency system has risen up but the best currency system has not still appeared. In this paper, we propose the model of “the currency basket peg system”. This model realize the currency basket peg system on the computer. With using it, we investigate ...

The Minority Game is a generic model of competing adaptive agents, which is often believed to be a model of financial markets. We discuss to which extend this is a reasonable statement, and present minimal modifications that make this model reproduce stylized facts. The resulting model shows that without speculators, prices follow random walks, and that they disappear if enough speculators take...

Adaptive autoreclosing is a fast emerging technology for improving power system marginal stability during faults. It avoids reclosing unto permanent faults and recloses unto transient faults only after the secondary arc has extinguished. This paper presents a comprehensive review of various adaptive autoreclosure techniques. It aims at providing a broad perspective on adaptive autoreclosing tec...

This paper is the ...rst attempt of applying the Easley Rustichini (Econometrica, 1999, 5) Replicator dynamics framework to simple one-period security markets, with a ...nite set of actions for traders. In two and three action environments, the examples developed here show that even with very simple (objective) state spaces and straightforward Replicator Dynamics, prices may not necessarily con...

This tutorial deals with the cognitive skills based adaptive educational environments an approach to designing tutoring systems that has been very effective, especially within applied domains where the learning is predominantly concerned with acquiring operational knowledge. Since such environments can accommodate both the 'instruction' and 'construction' of knowledge and actively engage the le...
