Three-dimensional (3-D) digital image correlation (DIC) has been gradually adopted by industry these years. This method utilizes a pair of cameras to accumulate and correlate images through tracking the movement of features on the specimen surface in real time. It is capable of generating both in-plane and out-of-plane deformation during one test. To some extent, it is perfect to be utilized in the...
According to the characteristics of power distribution system and the commonly used communication mode, the evaluation index system of the communication system for power distribution system, which includes 4 kinds of indexes, including economy, reliability, technology and security is established. Based on the set pair analysis, a comprehensive evaluation model of the communication system for power...
As one of the key options for distribution network modernization, distribution feeder-based MicroGrid (MG) is gaining increasing interest worldwide. However, there has been few work done on feeder-based MG and related issues in the literature. It is therefore necessary to devote some effort to identify the current state-of-the-art of feeder-based MG systems especially regarding potential issues that...
With the growth of people's living standard and economic income, the effect of prices is weakened while customers are shopping, but brand effect is increasingly obvious. This paper uses the customers' brand cognitive level as independent variable, and uses simulation scenario experiment method and use the eye tracker to record and analyze the eye movement data of the participants of different cognitive...
Here we demonstrate the copper/dielectric TDDB improvement of 8 metal layers in 28nm technology node with 90 nm pitch. After the process optimization, the Weibull slope of MOM TDDB increase from 0.85 to 1.28 that improves the estimated MOM TDDB about 200 times.
In view of objective shortage of the present technology readiness assessment (TRA) method, TRA method based on close degree is proposed. Such key techniques is introduced with examples, such as the determination of number of layers in reference condition, build-up of reference condition, selection of characteristic parameter in reference condition and the processing mode of the characteristic parameter.
Micro-expressions are facial expressions which are fleeting and reveal genuine emotions that people try to conceal. These are important clues for detecting lies and dangerous behaviors and therefore have potential applications in various fields such as the clinical field and national security. However, recognition through the naked eye is very difficult. Therefore, researchers in the field of computer...
The phenomenon of invalid entity relation tuples generating more invalid tuples in the next cycle is called as “circular dependencies” in relation extraction. In order to prevent the existence of the phenomenon of “circular dependencies”, we present a entity relation tuples filtration method that filters the invalid entity relation tuples for Weakly Supervised Relation Extraction. In our article,...
Reliability is one of the most important target in airplane designing, the redundancy technology is universally used in servo-actuator system of civil aircraft's Fly-by-Wire System (FBWS). In order to attain a high reliability, firstly the system structure is designed and redundancy allocation is given, accordingly the redundant management strategy and realization are described in detail. Based on...
The development of a SOPC for matching fingerprint images is presented in this paper. The major motivation for this work is to develop a fingerprint image matching handheld module, which can overcome the limitation of original phase correlation based algorithm and has more reliability performance to rotated and noisy images. By aid of Fourier-Mellin transform (FMT), frequency domain features are extracted...
Vacuum circuit breaker has advantages of low maintenance cost and high reliability. It reaches the priority in aviation field. This paper focuses on the arc modes of intermediate-frequency (400Hz-800Hz) vacuum arc in commercial-type vacuum interrupters with axial magnetic field (AMF) contacts. With high speed photography in conjunction with voltage-current characteristics, three different arc modes...
In order to reduce the congestion of Ad Hoc network and increase the speed of routing searching, the link-disjoint paths algorithm based on ant colony optimization is proposed in this paper. The new algorithm introduces the intelligence and positive feedback of ant algorithm to link-disjoint paths algorithm to improve the probability of path optimization, sets the age domain of ant to reduce immersion,...
The concept of median value based on confidence level for fuzzy numbers is proposed, and itpsilas discussed with triangular fuzzy numbers. Compared with the concept defined before, the median value based on confidence level could improve the membership level manifestly, and enhance the credibility of median to replacing fuzzy number visibly. The effectiveness and usefulness of median value based on...
