چکیده
In the early deployment of electric toll collecting (ETC) system, multipath interference has caused the malfunction of the system. Therefore, radio absorbers are installed in the toll gate to suppress the scattering. This paper presents a novel radio propagation measurement system to identify the individual scattering object and the power intensity of the ETC gate in real time.

Real-Time Propagation Measurement System and Scattering Object Identification by 3D Visualization by Using VRML for ETC System
In the early deployment of electric toll collecting (ETC) system, multipath interference has caused the malfunction of the system. Therefore, radio absorbers are installed in the toll gate to suppress the scattering effects. This paper presents a novel radio propagation measurement system using the beamforming with 8-elmenet antenna array to examine the power intensity distribution of the ETC g...

متن کاملFeasibility Study of Real-time and Automated Monitoring of Iranian Rivers using 50-kHz Fluvial Acoustic Tomography System
Acoustic Tomography (AT) technique is an innovative method for real-time river monitoring. In this study, not only the accuracy of flow velocity measurement using 50 kHz AT system which is appropriate for narrow rivers (most Iranian rivers) is evaluated, but also its performance is compared with 30 kHz one which is used in wide rivers. The comparison results showed that the velocity resolutions...
متن کاملRelevance of a Toll-Free Call Service Using an Interactive Voice Server to Strengthen Health System Governance and Responsiveness in Burkina Faso
Background In Africa, health systems are poorly accessible, inequitable, and unresponsive. People rarely have either the confidence or the opportunity to express their opinions. In Burkina Faso, there is a political will to improve governance and responsiveness to create a more relevant and equitable health system. Given their development in Africa, information and communication technolog...
