Timed event is an essential part of concurrent actor interaction. This paper presents predictable time-centric semantic framework for designing actor-oriented embedded control software on the distributed platform, which reduces complexity by separating actor's data-centric computational parts from timed interaction among actors. Actors are concurrent components. Signal, timed metric distance and causality...
The Urban Public Transportation Information Service System, for the bus arrival time showed on the intelligent electronic station board, is designed to provide accurate and timely information which can help travelers choose transit lines and the shortest paths, can improve the travel efficiency and attract more potential travelers. However, the current bus arrival time prediction model under application...
For the performance of networked control system is limited to the network resources and compute resources, the scheduling strategy is the key factor. This paper proposed two level schedule strategy: First, the controller and sensor nodes can be configured as event-time hybrid driven mode to improve the utilization rate. Then, considering the error and error difference response, a BP neural network...
