RSS Based Bridge Scour Measurement Using Underwater Acoustic Sensor Networks
Bridge Scour is one of the major causes of bridge failures all around the world and there have been significant efforts for its detection and measurement using different acoustic approaches. In this paper, we propose and investigate an effective method to utilize Received Signal Strength (RSS) for measuring scour depth where acoustic sensors are deployed. We also extend a statistical testing to...
متن کاملBridge Monitoring Using Wireless Sensors and Acoustic Emission Techniques
The inspection of bridges is currently made by visual inspection or by wired sensor techniques, which are relatively expensive, vulnerable to damage, and time consuming to install. In contrast, wireless sensor networks are easy to deploy and flexible in application so that the network can adjust to the individual structure. Different sensing techniques can be used with such a network, but acous...
متن کاملFluctuating dilatation rate as an acoustic source
1 Ribner's (1962) dilatational acoustic theory is revisited. A rigorous connection between the uctuating dilatation rate and the acoustic source eld is established; this vindicates Ribner's heuristic contention while indicating additional acoustic source terms in his dilatational acoustic theory. It is also shown that Ribner's acoustic source term is quadrupole. Interesting consequences of the ...
متن کاملDevelopment of Mems-based Ecf Micro Rate Gyro
We are proposing a liquid rate gyro named “ECF micro rate gyro”. Although the sensing principle is based on that of a conventional gas rate sensor, the liquid micro rate gyro works by an electro-conjugate fluid (ECF) instead of a gas. The electro-conjugate fluid is a dielectric fluid that works as a functional fluid, generating a powerful jet flow (ECF jet) when subjected to a high DC voltage. ...
متن کاملCharacterization of the Bell-Shaped Vibratory Angular Rate Gyro
The bell-shaped vibratory angular rate gyro (abbreviated as BVG) is a novel shell vibratory gyroscope, which is inspired by the Chinese traditional bell. It sensitizes angular velocity through the standing wave precession effect. The bell-shaped resonator is a core component of the BVG and looks like the millimeter-grade Chinese traditional bell, such as QianLong Bell and Yongle Bell. It is mad...
