This article describes a new approach in the Intelligent Training of Operators in Power Systems Control Centres, considering the new reality of Renewable Sources, Distributed Generation, and Electricity Markets, under the emerging paradigms of Cyber-Physical Systems and Ambient Intelligence. We propose Intelligent Tutoring Systems as the approach to deal with the intelligent training of operato...

We survey ways to extract information from users interacting in ambient intelligence entertainment environments. We speculate on the use of this information, including information obtained from physiological processes and brain-computer interfacing, in future game environments.

Broadcast mechanism is prevalent in many forms of electronic networks. Modeling broadcast protocols succinctly and reasoning about how secure these protocols are is gaining importance as society increasingly comes to depend on a wide variety of electronic communications. In this work we present a modified ambient calculus where the nature of communication is broadcast within domains. We allow r...

We give simple conditions on an ambient manifold that are necessary and sufficient for isoperimetric inequalities to hold.

A previous study by the first two authors suggests there is visual information for tone perception: under certain conditions Cantonese speakers are able to identify spoken words as one of six Cantonese words differing only in tone on the basis of lip and face movements at a rate better than chance [1]. Here, non-native (tonal, Thai, and non-tonal, English) language speakers were tested on a dis...

The success of Ambient Intelligence (AmI) will depend on how secure it can be made, how privacy and other rights of individuals can be protected and how individuals can come to trust the intelligent world that surrounds them and through which they move. This article addresses these issues by analysing scenarios for ambient intelligence applications that have been developed over the last few yea...

This work introduces a framework for modelling the main actors (human, artefacts and services) in a symbiotic Ambient Intelligence environment. It, also, proposes an architectural scheme that associates the social behaviour, which is not an inherent characteristic of the participants, during interaction with the functional behaviour of the participants of a Ubiquitous Computing application. The...

An important but often neglected aspect in Computer Supported Collaborative Learning is the intelligent formation of learning groups. Until recently, support for group formation was mostly based on learner profile information. However, the perspective of ubiquitous computing and ambient intelligence allows for taking a broader view on group formation, extending the range of features to include ...

We analyze the effect of collective action by green/environmentally aware consumers on ambient environmental quality and market equilibrium. We consider a model with two types of consumers who differ in their willingness-to-pay for a good available in two different environmental qualities, and two competing firms: one selling the good of high environmental quality and the other of low environme...
