Development of an instrumentation system embedded on FPGA for real time measurement of mechanical vibrations in rotating machinery
(2012-11-23)
The real-time monitoring of events in an industrial plant is vital, to monitor the actual conditions of operation of the machinery responsible for the manufacturing process. A predictive maintenance program includes condition ...
Double optical monitoring of time-dependent film formation
(2005-12-23)
A brief overview of optical monitoring for vacuum and wet bench film deposition processes is presented. Interferometric and polarimetric measurements are combined with regard to simultaneous real-time monitoring of refractive ...
Wireless sensor networks Zigbee applied on sewage treatment station
(2012-09-10)
The good efficiency in a sewage treatment plant (WWTP) is a great importance to the environment. The management of electromechanical equipment installed in these stations is a major challenge due to the fact that they are ...
Time-Domain Electromechanical Impedance for Structural Health Monitoring
(European Assoc Structural Dynamics, 2011-01-01)
Electromechanical impedance (EMI) technique is a very simple method that can be usefulness in most of Non-Destructive Evaluation (NDE) and Structural Health Monitoring (SHM) systems. A common application of EMI methods is ...
