RISThe Process of High-Frequency Intraseasonal Oscillation Associated with a Persistent Rainfall Event over South China
Publisher: American Meteorological Society
Anomaly Identification of Structural Health Monitoring Data Using Dynamic Independent Component Analysis
Publisher: ASCE
Abstract: Independent component analysis (ICA) has the potential to identify anomalies in structural health monitoring (SHM) data due to its non-Gaussian data-processing ability. In order to additionally take into account the dynamic ...
Numerical Simulation of the Transient Flow in a Centrifugal Pump During Starting Period
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Computational fluid dynamics were used to study the three-dimensional unsteady incompressible viscous flows in a centrifugal pump during rapid starting period (≈0.12 s). The rotational speed ...
Fabricating Lensed Fiber Using a Novel Polishing Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In optical communication systems, 980 nm high-power laser modules are applied for long-distance communication amplifiers. Since the mode field of the 980 nm laser diodes is different from ...
Analysis on Limit Equilibrium Zone of Coal Pillar in Mining Roadway Based on Mechanical Model of Elastic Foundation Beam
Publisher: American Society of Civil Engineers
Abstract: To reasonably determine the limit equilibrium zone width, a coal pillar was simplified as a half-infinite load-bearing beam while its weak floor rock mass was assumed to be a continuous elastic foundation according to the ...
Bayesian Combination of Weighted Principal-Component Analysis for Diagnosing Sensor Faults in Structural Monitoring Systems
Publisher: American Society of Civil Engineers
Abstract: It is essential to diagnose, i.e., detect and isolate, potential sensor faults for structural health monitoring to guarantee reliable condition evaluations. This paper proposes an innovative method called weighted ...
Sensor Fault Diagnosis for Structural Health Monitoring Based on Statistical Hypothesis Test and Missing Variable Approach
Publisher: American Society of Civil Engineers
Abstract: Using structural monitoring data collected from a sensor network to assess the health condition of a monitored structure relies on the accurate operation of the sensors and therefore could be affected by various sensor ...
