Here, we study scaling patterns of urban energy, water, and waste flows as well as other relevant measures in Chinese cities. We divide cities into different groups using an algorithm that ...

We propose a micro-ultrasonic diagnosis using an all-optical ultrasound-based spectral sensing ... serving as a screening modality to diagnose early stage clot formation (e.g., as an indicator for ...

As part of my TIPE (Travaux d'Initiative Personnelle Encadrés), I have developed an autonomous guidance system to assist visually impaired pedestrians. The device uses an ultrasonic sensor to detect ...

Wi-Fi controlled four-wheeled scout vehicle using ... ultrasonic sensor, turret rotation, and LCD display for real-time obstacle detection. As part of my TIPE (Travaux d'Initiative Personnelle ...

Traditional time-difference methods were found to be less effective for calculating water flow velocities using the proposed mobile ultrasonic transducers. By employing the AdaBoost algorithm with ...

Water level in Mullaperiyar dam stood at 114.40 feet (the maximum permissible level is 142 ft.) with an inflow of 294 cusecs and a discharge of 100 cusecs. In Vaigai dam, the level was 53.31 ft.

are built for use in harsh environments, offering resistance against extreme temperatures and providing protection against dust, steam, and fumes. According to the company, the ultrasonic sensors ...

Abstract: This paper presents a multi-ultrasonic ... Our multi-sensor structure can be applied to a multi-agent system, composed of 3 identical robots. Our results from preliminary experiments show ...

Abstract: An ultrasonic distance measurement system for use in air is presented. The measurement is based upon the two-frequency continuous-wave (TFCW) phase-shift method. In the system, two vernier ...
