Study Data from Sichuan University Update Knowledge of Mechanical Engineering

February 12, 2014

By a News Reporter-Staff News Editor at Journal of Engineering -- Investigators publish new report on Mechanical Engineering. According to news reporting from Chengdu, People's Republic of China, by VerticalNews journalists, research stated, "This article describes meta-synthesis information fusion as a novel mode in integrated avionic management systems. With deeper space explorations, avionic health management systems require more perfectly integrated data and information because of the increased spacecraft functionality and the complex software."

The news correspondents obtained a quote from the research from Sichuan University, "Meta-synthesis information fusion allows for a more accurate picture of the state of the avionics and therefore allows for better decision making. This study uses a meta-synthesis information fusion application for the hybrid diagnostics, which is a very important part of integrated health management systems. For the meta-synthesis information fusion, specific approaches such as probability theory, neural networks and the Dempster-Shafer evidence theory are used to construct the hybrid diagnostics model. Through this novel meta-synthesis information fusion mode, efficiency as a whole, from input to output is realized and dynamic, real-time diagnostics is achieved. A numerical example is given, which demonstrates the application of the hybrid diagnostics to a radar indicator."

According to the news reporters, the research concluded: "By analyzing the feasibility and the pragmatic utility of the hybrid diagnostics meta-synthesis information fusion, the advantages of this mode are shown."
