Distributed detection without fusion center (FC) allows each sensor node to exchange measurements with its neighbors and to reach agreement on the existence of the target using the consensus algorithm. Comparing with the centralized system, the decentralized system has better performance, in terms of robustness, scalability and invulnerability. Due to the decentralized and open properties, the security...
The Avionics Full Duplex switched Ethernet (AFDX) is widely used in the new generation of civil aircraft, such as A380 and Boeing787. Some research works have been conducted to optimize virtual links (VLs) design. However, a method that optimizes the VLs design scheme from the perspective of network performability is still missing. Furthermore, the configuration parameters interact with each other,...
The traditional static fault tree cannot capture the dynamic behavior of system fault mechanisms, so the dynamic fault tree has become one research hot spot now. Many scholars focus on the research of using the dynamic fault tree model and analyze for dynamic behavior of system fault mechanisms. However, in their studies they generally separate the software and hardware and analyze independently....
It is very hard and expensive to do reliability test for wireless mobile networks with its true form. OPNet is a simulation tool for network performance and reliability analysis, which is widely applied in industry. But a reliability simulation test design is usually absent when doing reliability evaluation on this platform. According to the traditional reliability test methods, this paper proposes...
Avionics systems play a significant role in civil aircraft, and its reliability is directly related to the flight safe. In this paper, integrated modular avionics (IMA), as the most advanced avionics systems, is analyzed. Via exploration of the interaction mechanism of IMA and real physical system, its property of cyber-physical systems (CPS) is determined. Hence, according to different functional...
According to observe diagnostics theory of Traditional Chinese Medicine (TCM), the lip color of one person is considered as symptoms and signs to diagnose whether his spleen or stomach is healthy or not. In traditional diagnostics method, the lip color is recognized by TCM master or veteran practitioner. The diagnostic result is affected not only by the doctor's knowledge and experience, but also...
The “black box” problem in neural network is being much concerned, which contributes to more and more researches on the structures of the neural network. Hierarchical neural network (HNN) is one kind of the neural networks that pays attention to the inner structure of network with the presentation of modular parts. In order to reducing the dependence of expert system in HNN, in the paper, a data attributes...
This paper describes a RF transceiver design for single chip Bluetooth SOC, which include RF, base band, MCU, and audio codec. The transceiver integrates all necessary functions for RX and TX mode. The RF matching network is also integrated on chip with one 50 ?? antenna pin without external switch and filters. Some key circuit blocks such as RF front-end, VCO, and fractional synthesizer are discussed.
