Impedance-Based Pre-Stress Monitoring of Rock Bolts Using a Piezoceramic-Based Smart Washer—A Feasibility Study
Pre-stress degradation or looseness of rock bolts in mining or tunnel engineering threatens the stability and reliability of the structures. In this paper, an innovative piezoelectric device named a "smart washer" with the impedance method is proposed with the aim of developing a real-time device to monitor the pre-stress level of rock bolts. The proposed method was verified through tests on a ...
متن کاملImage-based Bolt-loosening Detection Technique of Bolt Joint in Steel Bridges
This paper presents a novel bolt-loosening detection technique using image information of bolted joints in steel bridges. Firstly, existing bolt-loosening detection techniques are reviewed and their benefits and limitations are analyzed. Secondly, a bolt-loosening detection algorithm using image processing techniques is newly proposed for bolted joints in steel bridges. It consists of 3 steps: ...

متن کاملSpeaker Change Detection based on Mean Shift
To settle out the problem that search of speaker change point (SCP) is blind and exhaustive, mean shift is proposed to seek SCP by estimating the kernel density of speech stream in this paper. It contains three steps: seeking peak points using mean shift firstly, using maximum likelihood ratio (MLR) to compute the MLR value of the peak points secondly, and seeking SCPs from MLR value using the ...
متن کاملPerimeter Security Detection System Based on Piezoelectric Strain Measurement
A system is described that uses force-plate-mounted piezoelectric strain measurement to detect and quantify pedestrian traffic. The system uses distributed piezoelectric sensors in a stiff structural platform and is combined with a sensing and counting circuit. The paper describes the application of this technology for monitoring pedestrian traffic on a municipal trail. The application of the s...
