Because of importance to safety and product quality, the online monitoring of the welding process performance has become a key issue for safety improvement. In order to guarantee the laser welding quality, acoustic monitoring based on microphone array was employed to the laser welding for sampling the acoustic signals during the whole welding process. However, in the hostile industry environments,...
In this paper, a Spot Welding Quality Monitor System based on sensors array technique is applied in the course of the quality detecting. In order to use the monitor system more efficiently, the experiment in this study is designed into two parts. One part is the scheme selecting of the linear magnetic sensors array. The other is choosing a perfectible case to detect the process of the aluminum alloy...
Symbolic execution plays an important role in the area of software testing and program verification. However, there are several difficulties facing symbolic execution, one of which is how to abstract various data types in source codes. This paper addresses this problem by proposing a memory model that is based on the abstract symbol table. The abstract symbol table records names, abstract addresses...
