RISRobust Skewness-Kurtosis Descriptor for Damping Calibration from Frequency Response
Publisher: American Society of Civil Engineers
Abstract: This paper attempts to define simple, consistent, and robust statistical descriptors for the calibration of damping in linear and nonlinear systems through the frequency response in the presence of variability and uncertainties ...
Comparison of Response Amplitude Operator Curve Generation Methods for Scaled Floating Renewable Energy Platforms in Ocean Wave Basin
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Response amplitude operator (RAO) curves are commonly employed to assess the dynamic behavior of floating offshore structures in the frequency domain. There are multiple methods used to obtain RAOs for numerical models, ...
Ocean Wave Directional Distribution from GPS Buoy Observations off the West Coast of Ireland: Assessment of a Wavelet-Based Method
Publisher: American Meteorological Society
Impact of Sources of Damping on the Fragility Estimates of Wind Turbine Towers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fragility estimates in wind turbine towers have been investigated but the effect of damping on fragility has not been studied. While damping can often be small, it can come from different sources for a wind turbine. This ...
A Statistical Measure for Wavelet Based Singularity Detection
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a statistical measure for the identification of the presence, the location, and the calibration of the strength of singularity in a signal or in any of its derivatives in ...
Nondetection, False Alarm, and Calibration Insensitivity in Kurtosis- and Pseudofractal-Based Singularity Detection
Publisher: American Society of Civil Engineers
Abstract: This work isolates cases of nondetection, false alarm, and insensitivity for a general class of problems dealing with the detection and characterization of existence, location, and extent of singularities embedded in signals ...
Experimental Validation of Piezoelectric Energy-Harvesting Device for Built Infrastructure Applications
Publisher: American Society of Civil Engineers
Abstract: Vibration energy-harvesting devices are increasingly becoming more efficient and useful. The performance of such devices for energy harvesting from vibrations of civil infrastructure can be theoretically quantified, and ...
Special Section on Risk and Uncertainties in Offshore Wind and Wave Energy Systems
Publisher: The American Society of Mechanical Engineers (ASME)

Influence of Embedment on Seismic Pile Group Response: Experimental and Numerical Investigations
Publisher: American Society of Civil Engineers
Abstract: During seismic ground shaking, the motion of a soil–pile system is different from that of the free field due to seismic soil–structure interaction (SSI). Kinematic soil–pile interaction is known to cause significant filtering ...
