RISControllability Criteria for Soils Saturated by a Compressible Fluid
Publisher: American Society of Civil Engineers
Abstract: The liquefaction of sediments with gas bubbles occluded in the pore fluid can be studied neither through classical methods for saturated soils nor through concepts valid for unsaturated soils with continuous fluid phases. ...
Is Wetting Collapse an Unstable Compaction Process?
Publisher: American Society of Civil Engineers
Abstract: This paper provides an interpretation of the phenomenon of wetting collapse in fine-grained soils based on principles of material stability. For this purpose, classic experiments displaying the accumulation of irreversible ...
Solar Thermal Power for Lunar Materials Processing
Publisher: American Society of Civil Engineers
Abstract: Lunar in situ resource utilization (ISRU) processes require thermal energy at various temperatures. Chemical recovery processes (pyrolysis, gas-solid reactions, gas-liquid or three-phase reactions and desorption) require ...
Failure Surface for Concrete under Multiaxial Load—a Unified Approach
Publisher: American Society of Civil Engineers
Abstract: A new unified five-parameter failure surface has been proposed for use with normal strength (NC), high strength (HSC), and steel fiber-reinforced (SFRC) concrete under biaxial, triaxial, or axisymmetric loads. The study ...
Ingestion of Simulated SMAP L3 Soil Moisture Data into Military Maneuver Planning
Publisher: American Meteorological Society
Abstract: his paper uses simulated SMAP level-3 (L3) soil moisture data to calculate soil strength directly and compares the results against the current Noah Land Information System?based climatology approach. Based on the availability ...

Engineer Roles in Public Participation Process
Publisher: American Society of Civil Engineers
Abstract: Engineers often are key participants in required public participation processes. A case in point is the preparation of an Environmental Impact Statement which usually involves engineers as representatives of governmental ...
Comparison of Tropical Cyclone Motion and Environmental Steering
Publisher: American Meteorological Society
Abstract: Ten years of tropical cyclone motion data for the western North Pacific have been compared with coincident filtered 500 mb operational analyses of the Fleet Numerical Oceanography Center. The results indicate tropical ...
Using Digital Cloud Photogrammetry to Characterize the Onset and Transition from Shallow to Deep Convection over Orography
Publisher: American Meteorological Society
Abstract: An automated method for segmenting digital images of orographic cumulus and a simple metric for characterizing the transition from shallow to deep convection are presented. The analysis is motivated by the hypothesis that ...
Influence of Cement Type on Fiber–Matrix Interface Bond Strength
Publisher: ASCE
Abstract: This paper presents the results of an experimental investigation on the interface bond strength between reinforcing fibers embedded in a calcium sulfoaluminate (CSA) cement matrix, utilizing the single-fiber pullout test. ...
