“…Derived from this study, dificulties were found in accurately measuring and with low cost the wind speed inside a greenhouse, which leads to a calibration of a low cost anemometer. The calibration focuses on a hot-wire anemometer, which attempts to solve its main drawback, namely its loss of accuracy when air temperature or ambient temperature changes. …”

“…The experimental evaluation of the nebulizer, that is an inhalation catheter, has been made by means of a high speed camera, a pneumotach, an aerodynamic particle sizer, a precision balance and a hot-wire anemometer. Moreover, two physical models of the neonatal upper airways have been manufactured by rapid prototyping; one of them represents the neonatal trachea whereas the other one represents the respiratory system from the trachea to the third generation. …”
