Abstract: Ultrasonic guided waves have been used extensively for long-range pipe inspections. The technique is based on detecting the guided wave echoes reflected from pipe defects located at a remote ...

Abstract: A dense deployment of sensors is often beneficial for obtaining a more complete understanding of the dynamic behavior of complex structures, such as long-span bridges. Wireless smart sensor networks are advantageous in ...

Abstract: Civil infrastructure condition monitoring generates large volumes of sensor data. Huge data size impedes fast and reliable distribution of sensor data, especially for wireless sensor networks. Vibration sensor data plays ...

Abstract: This paper presents a novel systems approach to compressing sensor network data. Unlike previous data compression methods, the proposed lossless linear predictor-based sensor data compression method utilizes structural ...

Abstract: To realize atmospheric monitoring missions for carbon neutrality, this paper proposes an low earth orbit (LEO)-LEO occultation orbit design and optimization method for the user-specified point target revisit problem. First, ...

Abstract: This paper presents T-stress solutions for an internal edge crack in thick-walled cylinders. Elastic fracture mechanics analysis using the boundary element method (BEM) is performed to determine ...

Abstract: The Gezhouba Reservoir (GR) and Three Gorges Reservoir (TGR) are the two largest water-storage projects in the middle reach of the Yangtze River. The impoundments of the reservoirs have changed natural flow-regimes in the ...

Abstract: Structural strain responses, generally induced by traffic, wind, temperature, and so forth, can be used to evaluate the safety and serviceability of in-service bridges. According to one-year continuous monitoring of strain ...
