Lunar Base Construction Using the Reinforce Earth Method with Geotextile
This paper focuses on the construction of layered embankments using regolith and filmy materials (called geotextiles) with a robot machine before setting up of the cylindrical module on...
Taking Trash Out of Hiding
Out of sight, out of mind has been the country's solid waste mind-set. But when the $18 million Phoenix Solid Waste Management Center becomes fully operational in April, visitors...
Case Study - Performance of Diaphragm Walls During Construction; Predictions vs. Field Measurements
Rigid diaphragm walls (slurry walls) are being used more than any other earth supporting system for underground construction projects in confined downtown sites throughout the United States...
The Use of Coda Waves for Characterizing the Site Effect on Strong Ground Motion
The well established separability of source, path and site effects on coda waves of local seismic events offers the most effective means for determining the site amplification factor empirically....
Explorations in Geodesic Forms
Geodesic forms constitute an important family of structural systems. The objective of the paper is to show how the concepts of a mathematical tool called formex algebra and its programming...
Hyper-Geodesic Structures: Excerpts from a Visual Catalog
A class of hyper-geodesic surface structures is presented. The surfaces of known polygons, polyhedra, plane and space tessellations, higher dimensional polytopes can be subdivided into...
Assessing Effects for Disposal Sites off San Francisco
A simple particle tracking model has been used to estimate the size of deposition footprints and transient turbidity effects in the water column resulting from disposal of dredged material...
ASCE Salary Survey 1993
The 22nd biennial ASCE salary survey of the engineering profession conducted by the ASCE Committee on Employment Conditions during the first half of 1993 is presented. It consists of an...
The Politics of Nuclear-Waste Disposal
Spurred by federal and state legislation recommending local disposal of low-level radioactive nuclear waste, the Illinois-Kentucky Compact announced plans in the mid 1980s to build a disposal...
The Future of the Past: Historic Preservation at the Metropolitan Washington Airports
The historic significance and unique architectural character of Washington National and Washington Dulles International Airports have presented the Metropolitan Washington Airports Authority...
Willingness and Ability to Pay for Rural Water
Estimates of willingness to pay for rural water systems were developed in South Dakota, Oklahoma, and Montana from responses to contingent valuation surveys. Ability to pay was also estimated...
Site Characterization by Artificial Neural Networks
Recently, an optimal groundwater management model has been developed to treat groundwater remediation problems at Lawrence Livermore National Laboratory (LLNL). The objective of the model...
Designing Under Uncertainty When We Can Reduce Uncertainty: When is Another Observation Worth the Cost?
A method is presented that optimizes the selection of sites for observation of an uncertain parameter when that parameter is used in the risk-based design of an engineered system. The...
A Survey of Stormwater Infiltration Basins in the Puget Sound Region
A survey of 23 infiltration basins in the Puget Sound area was conducted to gain information on the performance of these systems and the degree of compliance with state agency guidelines....
An Interactive Regional Regression Approach to Estimating Flood Quantiles
In Texas, a computer program has been developed which will estimate flood quantiles for an ungaged site based on data from gaging stations with similar watershed characteristics. The user...
Low-Flow Frequency Analysis with Censored Data
Log-linear regression models are often fit to low-flow quantile estimates from gauged sites to obtain a relationship for estimating low-flow quantiles at ungauged sites. In some regions...
Survey of Stormwater Detention State of Practice
A survey of stormwater professionals in the United States and Canada was conducted by the Urban Drainage and Flood Control District in 1991 regarding the current state of practice in the...
Robotics for Challenging Environments
This volume,
OSHA and the Design Professional
Since the creation of the Occupational Safety and Health Administration, the question of how the role of design professionals - engineers and architects - relate to the safety of a construction...
A New Angle on Ground-Water Remediation
When engineers from Black & Veatch Waste Science (BVWS) went to Tinker Air Force Base to examine the site of a hazardous waste cleanup job the service had hired them for, they...
