Abandoned Hole Effect on Ultimate Strength of Mechanical Anchors in Tension
Publisher: American Society of Civil Engineers
Abstract: Postinstalled anchors are frequently installed with unpredictable abandoned drilled holes (ADHs) at the job site. While ADHs may have a reducing impact on the original ultimate tensile strength (Nu) of the anchor per the ...
Evaluating the Utility of Drought Indices as Soil Moisture Proxies for Drought Monitoring and Land–Atmosphere Interactions
Publisher: American Meteorological Society
Symbolic Deep Learning for Structural System Identification
Publisher: ASCE
Abstract: Closed-form model expression is commonly required for parametric data assimilation (e.g., model updating, damage quantification, and so on). However, epistemic bias due to fixing the model class is a challenging issue ...
Numerical Simulation of the Influence of Bored Pile Construction on Adjacent Existing Pile Foundation
Publisher: American Society of Civil Engineers
Abstract: The procedure of constructing the bored piles of a new bridge is simulated by using the three-dimensional finite element method. The variance of soil body stress, the deformation in each step of the construction, and the ...
Spectral Kurtosis–Based Method for Weak Target Detection in Sea Clutter by Microwave Coherent Radar
Publisher: American Meteorological Society
Abstract: new method is proposed to detect small targets embedded in sea clutter for land-based microwave coherent radar using spectral kurtosis as a signature from radar data. It is executed according to the following procedures. ...
Evaluating Radial Current Measurement of Multifrequency HF Radar with Multidepth ADCP Data during a Small Storm
Publisher: American Meteorological Society
Abstract: multifrequency high-frequency (MHF) radar system was designed and developed by Wuhan University in 2007. This system can simultaneously operate at four frequencies mainly in the 7.5?25-MHz band. This paper focuses on ...
A Practical Method of Extracting Wind Sea and Swell from Directional Wave Spectrum
Publisher: American Meteorological Society
Abstract: ind sea and swell representing different weather conditions generally coexist in both open waters and coastal areas, which results in bimodal or multipeaked features in directional wave spectrum. Because they make wave ...
Evaluating Two Array Autocalibration Methods with Multifrequency HF Radar Current Measurements
Publisher: American Meteorological Society
Abstract: ne pivotal factor affecting the accuracy of HF radar current measurements is the direction of arrival (DOA) estimation performance of the current signal. The beamforming technology or superresolution algorithm cannot always ...
Singularity Analysis and Dimensional Synthesis of a 2R1T 3-UPU Parallel Mechanism Based on Performance Atlas
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a symmetric 3-UPU (U and P represent universal and prismatic joints, individually) parallel mechanism and its variant mechanism under different geometric and assembly conditions are analyzed. Both have two ...
Triple Collocation Evaluation of In Situ Soil Moisture Observations from 1200+ Stations as part of the U.S. National Soil Moisture Network
Publisher: American Meteorological Society
