Electromagnetic relay has a high failure rate, which is the severely afflicted area where components and parts easily lose efficacy in the electronic system. Monitoring and evaluation of relay status in key positions are a crucial method to improve operational reliability. Degradation is the significant cause for failure of electromagnetic relay. However, owing to few researches concerning degradation...
Electronic product works in various complicated conditions during the whole life cycle. Predicting environmental worthiness, judging the ability to resist environmental stress and identify failure states are very important to life prediction and health management of the electronic product. In China, the environmental engineering work for electronic product still focuses on environment test, and few...
This paper introduces an improved statistical analysis method to avoid the calculation error in duty cycle distortion jitter analyzing. Statistical analysis method is a very effective algorithm for channel eye diagram calculation and it can include all jitter impaction through the probability distribution function of total jitter, but the result has error when it involves duty cycle distortion jitter,...
In order to overcome the drawback of the standard PSO, such as being subject to falling into local optimization, an improved PSO algorithm based on three sub-swarms exchange is proposed. Firstly the method divides the whole swarm into three sub-swarms which evolve jointly according to three different models, that is, one evolves with the standard PSO model, and the second with social only model and...
