چکیده
Vafa Ghazi-Moghadam M. Kaveh Department of Electrical Engineering, University of Minnesota, Minneapolis, MN 55455, USA ABSTRACT This paper addresses some practical issues in active array signal processing, such as signal design, calibration and algorithmically e cient processing for range and angle determination. First, the operation of an experimental ultrasound-in-air active sensing system is described, and the range and angle detection capabilities of the array are investigated. Then, the applications of CDMA-like techniques in a multisensor range detection system is demonstrated, and the performances of two types of codes are compared.

Measurement and Modelling of the Rubber Resilience based on Ultrasonic Non-destructive Testing in Tires
In tire industry, it is very crucial to evaluate physical and mechanical properties of the rubber which is used for production of the tire, to ensure the quality of the final product. Resilience is an important property of a rubber, which cannot be evaluated through direct measurement in production cycle in this industry. Therefore, non-destructive ultrasonic testing, which has been used in man...
متن کاملDesign of Nondestructive System for Hardness of Carbonitrided Steel Parts Using Eddy Current Testing Method: Case study on the Tappet Parts
In this paper, a non-destructive eddy current test system was designed to evaluate the surface hardness of the carbonitrided steel parts. For this purpose, various samples of the tappet were used after the surface hardening and grinding operations as control samples and, if necessary, were subjected to destructive and non-destructive tests. Microstructural studies were performed with a microsco...
متن کاملA scalarization-based method for multiple part-type scheduling of two-machine robotic systems with non-destructive testing technologies
This paper analyzes the performance of a robotic system with two machines in which machines are configured in a circular layout and produce non-identical parts repetitively. The non-destructive testing (NDT) is performed by a stationary robotic arm located in the center of the circle, or a cluster tool. The robotic arm integrates multiple tasks, mainly the NDT of the part and its transition bet...
