The C-scan presentations provides a plan-type view of the location and size of test specimen features. The plane of the image is parallel to the scan pattern of the transducer. C-scan presentations are produced with an automated data acquisition system, such as a computer controlled immersion scanning system. Typically, a data collection gate is established on the A-scan and the amplitude or the time -of-flight of the signal is recorded at regular intervals as the transducer is scanned over the test piece. The relative signal amplitude or the time -of-flight is displayed as a shade of Gray or a color for each of the positions where data was connected. The C-scan presentations provides an image of the features that reflect and scatter the sound within and on the surfaces of the test piece. High resolution scans can produce very detailed images. Both images were produced using a pulse-echo technique with the transducer scanned over the head side in an immersion scanning system. For t...

A computer is an electronic device that can process, store, retrieve, and transmit data. It can perform various tasks and instructions based on the software installed in it. The computer consists of hardware components like the central processing unit (CPU), memory, hard drive, monitor, keyboard, and mouse and software components like operating system, applications, and programs. The computer has revolutionized the way we work, learn, communicate, and entertain ourselves, making our lives more convenient and productive. The basic parts without which a computer cannot work are. 1)   Central Processing Unit (CPU): It is the brain of the computer that performs all the calculations and instructions 2)   Random Access Memory (RAM): It is a temporary memory that stores the data and instructions for the CPU to access quickly. 3)  Storage: It is a device that stores data permanently, such as a hard drive or solid-state drive. 4)  Motherboard: It is the main ...
