This research demonstrates very promising results of using compressed sensing for ultrasonic signal reconstruction
Introduction
Ultrasonic inspection is an effective tool for flaw detection/evaluation, material characteristic measurement, and environmental monitoring.
The typical principle is to transmit ultrasonic signal through the material and receive the transmitted wave at a distance for evaluation.
We first assume aluminal material is used.
The key to success of using compressed sensing for ultrasonic signal reconstruction is the choice of basis Y.

Abstract.
For the sake of attract the attention of the visitors, the modern zoo invented the environmental movement for animals and made the behavior of them rich and colorful, such as provide artificial termite nest (Putting yoghourt, honey or peanut butter inside a thin tube son.) for gorillas. ④Make use of new technique, new material to imitate a true animal living environment.
Artificial material can imitate a tropical animal exhibition area, and can also imitate a desert animal or a polar animal exhibition area [2].
The gorilla building adopts energy-saving porous brick, hollow bricks as main building materials.
