Operational modal analysis (OMA) is important for continuous structural health monitoring (SHM) of in-service offshore jacket platforms. In practice, long monitoring records increase the computational cost of SSI, while environmental and measurement interference can affect the recorded response. This study applies a hybrid procedure combining Kalman filtering (KF), the Random Decrement Technique (RDT), and Stochastic Subspace...

Primates, 69% of which are threatened with extinction, are the third most specious order of mammals. We used primates as model taxa to examine the umbrella effects of primates on ecosystem services and the protection of other vertebrates and seed plants in Yunnan Province, China. We identified areas of conservation priority for 16 primate species and determined which other threatened and endemic terrestrial vertebrates and see...
