While collaboration is a natural choice in many situations, there is a lack of specialized tools for collaboratively seeking information. We present design specifications and impl...
This paper describes design criteria for creating highly embedded, interactive spaces that we call Intelligent Environments. The motivation for building these systems is to bring ...
This paper gives a semantics for discrete-event (DE) models that generalizes that of synchronous/reactive (SR) languages, and a continuous-time (CT) semantics that generalizes the...
The design of collusion-free codes for data hiding systems is investigated, and two new collusion-free codes are proposed in this work. They are called the Orthogonal Spreading (O...
This paper presents an approach to the design of a learning environment in a mathematical domain (elementary combinatorics) where problem solving is based more on modelling than o...
