RISFull-Scale Experimental Study on the Degradation of Pile-Supported Embankment due to Water Infiltration
Publisher: American Society of Civil Engineers
Abstract: AbstractStress transfer within pile-supported embankments is influenced by soil arching, and
this phenomenon is assumed to be water uptake-dependent. In this study, a full-scale
model of high-speed railway pile-supported ...
Identifying Doppler Velocity Contamination Caused by Migrating Birds. Part II: Bayes Identification and Probability Tests
Publisher: American Meteorological Society
Abstract: Based on the Bayesian statistical decision theory, a probabilistic quality control (QC) technique is developed to identify and flag migrating-bird-contaminated sweeps of level II velocity scans at the lowest elevation angle ...
Identifying Doppler Velocity Contamination Caused by Migrating Birds. Part I: Feature Extraction and Quantification
Publisher: American Meteorological Society
Abstract: Radar echoes from migrating birds can severely contaminate Doppler velocity measurements. For meteorological applications, especially quantitative applications in radar data assimilation, it is necessary to remove ...
Variational Analysis of Oversampled Dual-Doppler Radial Velocity Data and Application to the Analysis of Tornado Circulations
Publisher: American Meteorological Society
Abstract: For the detection of severe weather phenomena such as tornados, mesocyclones, and strong wind shear, the azimuthal resolution of radial velocity measurements is more important. The typical azimuthal resolutions of 1° for ...
Using Wavelet Analysis to Detect Tornadoes from Doppler Radar Radial-Velocity Observations
Publisher: American Meteorological Society
Abstract: A wavelet-based algorithm is developed to detect tornadoes from Doppler weather radar radial-velocity observations. Within this algorithm, a relative region-to-region velocity difference (RRVD) is defined based on the ...
Rankine Active Earth Pressure of Unsaturated Soil Based on the Envelope Shell Model
Publisher: American Society of Civil Engineers
Abstract: Abstract In this study, a novel approach for the active earth pressure on retaining wall with
unsaturated backfill is proposed based on the nonlinear shear strength envelope shell
model and classical Rankine theory. This ...
An Improved Time Interpolation for Three-Dimensional Doppler Wind Analysis
Publisher: American Meteorological Society
Abstract: A temporal interpolation is required for three-dimensional Doppler wind analysis when the precise measurement time is counted for each radar beam position. The time interpolation is traditionally done by a linear scheme ...
A VAD-Based Dealiasing Method for Radar Velocity Data Quality Control
Publisher: American Meteorological Society
Abstract: This paper describes a new velocity?azimuth display (VAD)-based dealiasing method developed for automated radar radial velocity data quality control to satisfy the high-quality standard and efficiency required by operational ...
A Coupled Model for the Prediction of Surface Variation in Face Milling Large-Scale Workpiece With Complex Geometry
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Face milling commonly generates surface quality of variation, is especially severe for milling of large-scale components with complex surface geometry such as cylinder block, engine head, and valve body. Thus surface ...
A Simplified and Efficient Method for Water Flooding Production Index Calculations in Low Permeable Fractured Reservoir
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Presently, predicting the production performance of fractured reservoirs is often challenging because of the following two factors: one factor such as complicatedly connected and random distribution nature of the fractures ...
