Prediction of noise and vibrations induced by construction activities in nearby buildings. Experimental measures.
Design of vibration energy reuse systems for remote sensing systems.
Predictive maintenance procedure based on acoustic emission (very high frequency vibration). The detection of structural faults by acoustic emission has the advantage that it detects changes in the microscopic phase and allows maintenance tasks to be anticipated well in advance. This technique can be applied for the detection of multitude of phenomena, such as leak detection, structural integrity, corrosion detection.
