In order to solve the problem that the accuracy of flaws identification in ultrasonic testing is not high enough due to the error in sensor information acquisition and the noise interference in the detection environment, a method of flaws identification in ultrasonic testing based on evidential reasoning rule (ER rule) is studied. Firstly, ER rule is proposed to consider the reliability and weights...
In order to solve the problem of low accuracy of flaws detection in non-destructive testing, a data-fusion method based on RBF neural network and evidential reasoning (ER) rule is studied. Firstly, a data-fusion model is proposed which contains two parts. Secondly, the first part RBF neural network is used to fuse the feature layer, and its output is normalized as the basic probability assignment...
In this paper, an improved LDPMOS_SCR without a LDPMOS structure (NonLDPMOS_SCR) is discussed, which is realized in 0.5-μm 5V/18V/24V CDMOS process. The theoretical analysis and transmission line pulse (TLP) testing system are used to predict and characterize the proposed ESD protection devices. According to the measurement results, compared with the normal LDPMOS_SCR, NonLDPMOS_SCR elevates the second...
Multi-class learning is an important task in Data Science. One of the ways to achieve good performance on this task is to use Error Correcting Output Codes (ECOC), which is a powerful ensemble learning method that transforms a multi-class problem into a series of binary classifiers which it uses indirectly to learn the original multi-class problem. A crucial component of ECOC is the design of the...
In this paper, two kinds of planar monopole excited by UWB pulse are analysed using MOD method. In UWB antenna structure, the thin cylindrical probe is modelled as a thin strip which can be meshed easily by RWG basis functions. Then transient responses of surface current for UWB antennas are obtained.
Abnormal sintering state is often caused by the changes of improper operation in the sintering process of rotary kiln. If not addressed immediately, control system performance will be deteriorating, and even the crash will be caused. Current approaches of pattern recognition cannot be applied immediately to recognizing such abnormal sintering state of rotary kiln. Therefore, integrating both image...
This paper proposes a numerical method for solving time domain electric field integral equation (TD-EFIE) so as to capture the wideband transient surface current of irregular conductive objects. The methodology is based on curved triangle RWG (CRWG) basis function combined with Laguerre polynomials as temporal variation, instead of customary planar triangle RWG expansion with matching-on in time (MOT)...
