The paper has analyzed the problems discovered in the application validation of a certain NOR FLASH for aerospace use, and clarified that the failure of this FLASH belongs to bit interference caused by over-erase. At the same time, the failure mechanism has also been analyzed, which is found to be discreteness of chip manufacturing process and incomplete coverage of the test; additionally, evasion...
A readiness comprehensive evaluation method is presented for the aerospace components in view of their whole life cycles in the paper, which is applicable for the production, design and usage of components in China and the complex aerospace environment. In this evaluation method, the corresponding index is introduced and quantified with the component performance classification taken into consideration...
Background We aimed to examine the effect of Roux-en-Y gastric bypass surgery (RYGB) on erectile dysfunction (ED), cavernosal morphological vasculopathy, and carotid wall alterations in severely obese Chinese men. Methods We performed a retrospective cohort study of 39 obese men with ED who underwent RYGB between 2011 and 2012. Erectile function was assessed by the International Index...
An embedded auto-calibration approach used in Vector Network Analyzer (VNA) is presented in this paper. To avoid the mismatch between calibration plane and measurement plane, the electronic standards are characterized by a novel method. The good performance of the approach is shown by measurement results.
With the demand of the engineering application, a method of the multi-model reference fault tolerant control is proposed. Fault models are classified detailedly, and the faults taking place in the system are identified, located, and diagnosed via neural network. A feasible multi-model reference active fault tolerant control method is proposed. Finally, a simulation example is used to demonstrate the...
Action potential duration (APD) alternans is believed to be a loss of stability and contributes much to the reentry arrhythmias. The purpose of this study is to analyze the stability conditions for one-dimension model and higher dimension model. These criterions are concluded by linear stability analysis in nonlinear dynamics. They should be useful for finding of cardiac control algorithms in low...
