简介:基于伴随的优化方法是在turbomachinery的一个热点。首先,这份报纸更多样地从Lagrange论述伴随方法的原则观点。第二,把一条连续线路与薄层RANS方程相结合,我们提出伴随方程和反物理的边界条件。由于在turbomachinery的多级式的环境,混合方法的伴随interrow被介绍。解决流动方程和伴随方程的数字技术是几乎一样,并且一旦他们分别地被集成,一个目的坡度工作设计变量能高效地用复杂方法被计算。第三,集成形状不安parameterization和一个简单最陡峭的降下方法,为多级式的turbomachinery的基于伴随的空气动力学的形状优化的一个框架被构造。最后,环形的串联的一个反的图案被采用验证一台Aachen1.5阶段汽轮机的上述途径,和伴随地表明伴随的保存和areflexiainterrow混合方法。然后1+1的直接重新设计相反旋转的汽轮机试图增加效率并且把限制用于集体流动率和压力比率被拿。

简介:在连续语音识别的音调模型集成的一个歧视的框架被建议。放大隐藏的Markov模型的可能性基于的方法使用模型依赖者重量光谱特征和音调模型基于音调的features.The重量是有区别地由最小的电话错误标准的trahined。模型重量的更改方程基于扩大Baum-Welch算法被导出。模型重量联合的各种各样的计划被评估,一种变光滑的技术被介绍成为训练对柔韧在适合上。建议方法是音调的音节输出和字符输出语音识别任务上的ewluated。试验性的结果证明建议方法由于给定的模型的更好的插值在二项任务比全球重量获得了9.5%和4.7%相对错误减小。这为音调模型集成证明歧视的训练模型重量的有效性。
