Article Synopsis
- This text discusses a sonic anemometer designed to measure wind speed on Mars, where conditions include low CO2 pressure and extreme temperatures.
- The study evaluates four different transducers to identify their performance, revealing how temperature and pressure impact measurement accuracy.
- Findings suggest that while some transducers show higher measurement errors, others perform better, with potential applications also including stratospheric anemometry for Earth's high-altitude balloon missions.
Purpose: The purpose of this paper was to take the first steps toward applying noncontact ultrasound (NCU) to the tasks of monitoring osteoporosis and quantitative ultrasound imaging (QUS) of cortical bone. The authors also focused on the advantages of NCU, such as its lack of reliance on a technologist to apply transducers and a layer of acoustical coupling gel, the ability of the transducers to operate autonomously as specified by preprogrammed software, and the likely reduction in statistical and systematic errors associated with the variability in the pressure applied by the clinician to the transmitting transducer that NCU might provide. The authors also undertook this study in order to find additional applications of NCU beyond its past limited usage in assessing the severity of third degree burns.
