In this paper a method is presented for measuring awareness of external events while interacting with a virtual world. This study examines the relation (if there exists any) between the user awareness and the presence felt in a virtual world during use of immersive displays. An experiment

This paper presents risk and sensitivity analysis of external events impacts on the safe operation in general and in particular the Ignalina Nuclear Power Plant safety systems. Analysis is based on the deterministic and probabilistic assumptions and assessment of the external hazards. The real

This paper presents SIENA, an event notification service that we have designed and implemented to exhibit both expressiveness and scalability. We describe the service's interface to applications, the algorithms used by networks of servers to select and deliver event notifications

Advanced nuclear plant design options to cope with external events

In the reference letter, the NRC issued a Request for Additional Information (RAI) related to the Individual Plant Examination of External Events (IPEEE) assessments for fire events for the Braidwood Station and the Byron Station. As requested, we have focused our attention and responses

I describe a planning methodology for domains with uncertainty in the form of external events that are not completely predictable. Under certain conditions, these events can be modelled as continuous-time Markov chains whose states are characterised by the planner's domain predicates

to drive an intelligent agent, however, do not incorporate concepts to handle such world dynamics. An action usually has a definite effect — without a possibility of further indirect consequences. Some planning systems allow for the occurrence of external events, but do not enable relations to an agent’s

We propose a new design for highly concurrent Internet services, whichwe call the staged event-driven architecture (SEDA). SEDA is intended

, clear separation between mechanism and policy, and extensibility. To achieve these ends, Bro is divided into an “event engine” that reduces a kernel-filtered network traffic stream into a series of higher-level events, and a “policy script interpreter” that interprets event handlers written in a
