Cyber-physical systems (CPS) are becoming ubiquitous. Almost every device today has a controller that reads inputs through sensors, does some processing and then performs actions t...
We present a novel approach to non-monotonic ILP and its implementation called tal (Top-directed Abductive Learning). tal overcomes some of the completeness problems of ILP systems...
Checkpointing and replaying is an attractive technique that has been used widely at the operating/runtime system level to provide fault tolerance. Applying such a technique at the...
We propose a sensornet programming model based on declarative spatio-temporal constraints on events only, not sensors. Where previous approaches conflate events and sensors becaus...
Abstract. In this paper the methodology followed to build a questionanswering system for the Portuguese language is described. The system modules are built using computational ling...
