The growing adoption of automated data collection systems in the transit industry, such as automated fare-collection (AFC) and automated vehicle location (AVL), is providing operators with extensive data about the state of the system and its usage by passengers. The paper proposes a framework for using automated data to support the various functions, both planning and real time, and demonstrates its...
A general metric function of carrier lock detection, based on Mth-power for MPSK signal is proposed. The expectation of this metric function's output is independent of noise, only related to the signal power. It is easy to judge the carrier loop whether in a lock state or not, with low complexity cost. By median filtering the output of metric function, the reliability of carrier lock detection could...
Service composition is a key issue in the pervasive computing systems of service orientation. Automatically converting web services composition plans into BPEL4WS is an essential step in SASO (Semantic and Automatic Service Orchestration system). In this paper, we employ DAG to represent web services composition plans, and propose an automatic conversion algorithm BPELGEN which automatically converts...
