  • a telemedicine management model based on Message Trigger service
    Methods of Information in Medicine, 2000
    Co-Authors: Jing Bai
    Abstract:

    A telemedicine system model, based on a Message-Trigger service, is described. This model distributes system applications on multiple computers and establishes a communication platform to exchange Messages among all applications. By broadcasting event Messages, an application is able to Trigger a set of local and remote services. At the same time, a protocol for Message exchange is proposed to fulfill cooperation of applications. To validate the model, a teleconsultation system is designed. The results indicate that the model has good compatibility and that the characteristics are easy to implement.

  • performance and channel load evaluation for contextual pedestrian to vehicle transmissions
    Proceedings of the First ACM International Workshop on Smart Autonomous and Connected Vehicular Systems and Services, 2016
    Co-Authors: Ali Rostami, John Kenney, Bin Cheng, Marco Gruteser
    Abstract:

    Communication between pedestrians' mobile devices and vehicles can play a vital role in improving traffic safety. Enabling such communication is challenging in areas where pedestrian density is high, since transmissions from all pedestrians could lead to high channel load, co-channel interference, and degraded communication performance. To understand these challenges, we first introduce a high-density pedestrian simulation scenario modeled after the Times Square neighborhood in New York City. We then evaluate the channel load in terms of Channel Busy Percentage (CBP) under several contextual safety Message Trigger policies and different transmission rates. The study uses the Network Simulator 3 (ns-3) with mobility traces generated from a calibrated Simulation of Urban MObility (SUMO) model. The results show that higher transmission rates (5Hz) for all pedestrians lead to high packet error rates, which raises questions about whether application performance requirements can be met at such rates. The results also show that context-aware Trigger policies can significantly reduce channel load and lower latency (inter-packet gaps).

  • analyses of aircraft maintenance Message Trigger logic
    Journal of Civil Aviation University of China, 2007
    Co-Authors: Huang Zhiguang
    Abstract:

    Most Researches on aircraft fault diagnosis field are initialized from aircraft fault data.We stilled lacked necessary knowledge on how failures are generated and processed onboard the aircraft.As the result,the ground system designed to diagnose the aircraft fault is hard to match the aircraft system and fault Trigger logic.To fulfill this blank area,the article proposed a new method that the aircraft fault diagnosis ground module development should be fitted aircraft fault Trigger logic.The research on aircraft fault Trigger logic and process method will provide a fundamental base to the next step.

  • two distinct destabilizing elements in the c fos Message Trigger deadenylation as a first step in rapid mrna decay
    Genes & Development, 1991
    Co-Authors: Annbin Shyu, Joel G Belasco, Michael E Greenberg
    Abstract:

    The mechanisms by which c-fos mRNA is targeted for decay have been examined. Rapid removal of the poly(A) tail occurs before the transcribed portion of the c-fos Message is degraded. Identification of the determinants that mediate c-fos Message deadenylation reveals that they coincide directly with previously characterized determinants of c-fos mRNA instability, one in the protein-coding region and the other an AU-rich element (ARE) in the 3'-untranslated region. Insertion of either of these c-fos instability elements into the stable beta-globin Message confers the property of rapid deadenylation. Mutation of the ARE indicates that this sequence controls two steps in the process of c-fos mRNA degradation: removal of the poly(A) tail, which does not require intact AUUUA pentanucleotides within the ARE, and subsequent degradation of the transcribed portion of the Message, which appears to be dependent on the AUUUA pentanucleotides. These results indicate that structurally distinct instability determinants within the transcribed portion of labile Messages can function by promoting rapid removal of the poly(A) tail as a first step in the decay process.
