Portable consumer devices are increasing more and more their capabilities and can now implement new multimedia algorithms that were resewed only for powerful workstations few years ago. Unfortunately, the original design characteristics of such algorithms ...
We propose a novel approach to the composition of group communication protocols. In this approach, components are modelled as finite state machines communicating via signals. We introduce two building blocks, called adaptor and adaplexor, that ease the dev ...
A key challenge for neural modeling is to explain how a continuous stream of multimodal input from a rapidly changing environment can be processed by stereotypical recurrent circuits of integrate-and-fire neurons in real time. We propose a new computationa ...
This paper addresses the fundamental tradeoffs in event systems between scalability (of event filtering, routing, and delivery mechanisms), expressiveness (when describing interests in events), and event safety (ensuring encapsulation and type-safe interac ...
We design and study newObj, a calculus and dependent type system forobjects and classes which can have types as members. Type members canbe aliases, abstract types, or new types. The type system can modelthe essential concepts of Java's inner classes as we ...
We present an example of a construction of an embedded software system-a controller-from the formal specification to executable code. The CO-OPN (Concurrent Object Oriented Petri Net) formal specification language is used for modelling the controller and t ...
In support of flexible composition, components need to be adaptable and they need to have first-class plugs. Abstract state machines and object-oriented programming each satisfy one of these requirements very well but satisfy the other only incompletely. T ...
This report presents a response to the call for candidates issued by the National Institute for Standards and Technologies (the Advanced Encryption Standard project). The proposed candidate - called DFC as for "Decorrelated Fast Cipher" - is based on the r ...
