Modal identification of damaged frames
Structural Control and Health Monitoring, 2015 Summary The paper investigates the possibility of identifying localised damages for multi-span and multi-floor linear elastic frames using only natural frequencies measured in the undamaged and damaged configurations. Namely, frames of increasing complexity are studied by exploring one by one their significant substructures (i.e.

Learning Modal-Invariant and Temporal-Memory for Video-based Visible-Infrared Person Re-Identification [PDF]
Computer Vision and Pattern Recognition, 2022 Thanks for the cross-modal retrieval techniques, visible-infrared (RGB-IR) person re-identification (Re-ID) is achieved by projecting them into a common space, allowing person Re-ID in 24-hour surveillance systems.
