An ultrasonic system for measuring the quality of bananas

This thesis is about using ultrasonic technique to measure the quality of bananas by distinguishing the maturity stages of bananas. Ultrasonic waves which are propagated through banana specimens will be attenuated. The attenuation can be calculated and used to determine the maturity level of the ban...
