One-Way Thermo-Mechanical Coupled System Identification Using Displacement and Temperature Measurements

本文提出了一种基于优化和伴随方法的单向热 - 力耦合系统识别框架,通过单块或分区策略同时反演结构刚度损伤与温度场分布,显著提升了在传感器稀疏或局部热特征未被充分采样情况下的损伤定位与温度重构精度。

Refined Estimates on the Dimensions of Maximal Faces of Completely Positive Cones

本文通过证明奇数维完全正矩阵锥的最大面维数下界精确为nn,并给出偶数维n8n \geq 8时该下界位于nnn+3n+3之间的新估计,显著细化了现有理论中关于完全正矩阵锥最大面维数的界限。
