Detection of Broken Strands of Transmission Line Conductors Using Fiber Bragg Grating Sensors
Sensors, 2018 Transmission lines are affected by Aeolian vibration, which causes strands to break and eventually causes an entire line to break. In this paper, a method for monitoring strand breaking based on modal identification is proposed.

Model Updating Using Measurements from Sensors Installed in Arbitrary Positions and Directions
Applied Sciences, 2019 The present study proposes a method for model updating using measurements from sensors installed in arbitrary positions and directions. Modal identification provides mode shapes for physical quantities (acceleration strain, etc.) measured in specific ...

Bayesian FFT modal identification for multi-setup experimental modal analysis
Mechanical Systems and Signal ProcessingIn full-scale forced vibration tests, the demand often arises to capture high-spatial-resolution mode shapes with limited number of sensors and shakers. Multi-setup experimental modal analysis (EMA) addresses this challenge by roving sensors and shakers across multiple setups.

Infrared-Visible Cross-Modal Person Re-Identification with an X Modality
Proceedings of the AAAI Conference on Artificial Intelligence, 2020 This paper focuses on the emerging Infrared-Visible cross-modal person re-identification task (IV-ReID), which takes infrared images as input and matches with visible color images. IV-ReID is important yet challenging, as there is a significant gap between the visible and infrared images. To reduce this ‘gap’, we introduce an auxiliary X modality as an

Structural Responses of a Supertall Building Subjected to a Severe Typhoon at Landfall
Applied Sciences, 2020 Typhoon Mangkhut (1822) was one of the strongest tropical cyclones that ever impacted the south coast of China in past decades. During the passage of this typhoon, the structural health monitoring (SHM) system installed on a 303 m high building in this ...

Modal identification of a wind turbine.
Procedia Engineering, 2017 Abstract This work presents the numerical and experimental analysis to obtain dynamic parameters of a twisted type blade, that composes the wind turbine VERNE555 of Brazilian company ENERSUD, based in Rio de Janeiro. The experimental analysis performed the characterization of the modal parameters (frequencies and modal shape) of a wind turbine of 2 ...

Modal identification for hysteretic structure [PDF]
The Journal of the Acoustical Society of America, 1989 This work describes a method of analyzing the vibration response of a viscoelastic beam. The equation of motion of the transverse vibration of a beam with viscous damping and temporal hysteresis is given. Several methods for measuring the constants of a given hysteresis kernel are presented.
