梯度增强 Stochastic Co-Kriging 模型建模 CFD非嵌入式 不确定性量化
2019/10/16
作为一项极其复杂的系统工程，飞行器的研制总会受到制造误差、飞行状态等诸多不确定性因素的影响，如果这些不确定性因素在设计过程中被忽视，很可能会导致飞行器整体性能急剧变差，甚至造成致命性的灾难。因此，近年来飞行器的不确定性研究方法和手段在航空航天领域得到了广泛应用，NASA早在2002年就开始着手规划考虑不确定性因素影响的研究工作，AIAA和ASME每年都举办关于不确定性研究的专题研讨会。当前我国各型...

Sonority variation in Stochastic Optimality Theory: Implications for markedness hierarchies
Sonority variation Stochastic Optimality Theory
2014/4/25
Constraints based on the sonority scale and other markedness hierarchies have been formalized
in two different ways: as scale-partition constraint families, with a universally fixed ranking, and
as...
