医者的信仰是什么——秉承仁爱之初心,恪守希波克拉底誓言及南丁格尔誓言,救死扶伤,发扬革命的人道主义。心脏科、心脏血管外科作为“守护心脏”最直接的两个科室,也是离死亡更近的科室,我们争分夺秒,救治生命,诠释医者的誓言。
为了确保电气设备的安全可靠运行，提出基于主成分分析法与宽度学习系统的逆变器故障诊断方法。利用主成分分析法对逆变器输出的电流信号进行处理，提取信号特征；构建宽度学习系统，并编写不同故障模式下的故障编码；利用不同故障模式下的信号特征对宽度学习系统进行训练，利用网络输出编码实现故障分类。仿真结果表明，该研究方法在诊断准确率及训练时间方面优于传统的神经网络故障诊断方法。
Efficient hash maps to G2 on BLS curves
pairing-based cryptography pairing-friendly elliptic curves fast hashing
2017/5/23
When a pairing e:G1×G2→GTe:G1×G2→GT, on an elliptic curve EE defined over FqFq, is exploited for an identity-based protocol, there is often the need to hash binary strings into G1G1 and G2G2. Traditio...
基于ＴＤＬＡＳ ｂＬＳ方法的夏玉米农田氨挥发研究
可调谐二极管激光光谱技术 反向拉格朗日随机扩散模型 夏玉米 氨挥发 通气法
2012/12/6
采用开放光程可调谐二极管激光吸收光谱技术和反向拉格朗日随机扩散模型，通过田间试验，开、展基于高时间分辨率数据的农田氨挥发研究，旨在为揭示农田氨挥发的动态变化规律提供新技术新方法。结果表明，ＴＤＬＡＳｂＬＳ法能有效监测农田氨挥发动态，尤其是日内变化规律。豫北平原潮土农田夏玉米追肥后日内氨挥发有两个挥发峰值，分别在９：００和１４：００左右，第一个高峰是由于夜晚溶解在露水中的氨气随露水蒸发而再次挥发，...
