A Commonality Assessment of Lunar Surface Habitation
This paper presents a commonality assessment of lunar surface habitation. Thus far, NASA has baselined the space station common module for initial lunar base habitation; however, nothing...
Active Control of Flexural Vibrations in Beams
The feasibility of using piezoelectric actuators to control the flexural oscillations of large structures in space is investigated. Flexural oscillations are excited by implusive loads...
Robotic Influence in the Conceptual Design of Mechanical Systems in Space and Vice Versa: A Survey
A survey is presented of the methods of constructing structural elements in space by the application of robotic devices. Two fundamentally different approaches to the solution of robotic...
The Planar Truss - An Active Control Test Bed
The authors have developed a laboratory planar truss and structural dynamic models which correlate well. The inherent fraction critical damping (? = .004 for the first mode) is very low...
Comparisons Between Space Facilities and Earth-Based Analogs
This presentation will focus on the design of planetary bases and space stations as based on comparative designs for facilities in analogous harsh and isolated environments here on Earth....
Advanced Technology for a Lunar Astronomical Observatory
Significant new technologies are required for three proposed telescopes to be operated on the Moon. These technologies are in the areas of contamination/interference control, test and...
Highway Safety - Is the Job Finished?
A review of past measures undertaken to improve highway safety is given. The Highway Safety Acts have helped reduce the number of injuries and fatalities in spite of the increased number...
Historical Changes in Highway Safety: 1966 - 1987
During the past several decades, substantial changes have occurred in the national economy and culture. Corresponding changes have taken place in the highway transportation system. While...
Benefits of Highway Safety Improvement Programs
Even at the most conservative estimate of 2% annual growth in travel, the U.S. would experience almost 58,000 deaths in the year 2000 at a death rate of 2.5 per 100 million miles traveled....
Guide for Design of Steel Transmission Towers
ASCE Manual 52,
New Found Youth for an Old Foundry
The Grey Iron plant, central foundry division of General Motors Corp., in Saginaw, Mich. conducted a study to evaluate the capacity and tooling of future casting operations of the more...
Aeration
A Wastewater Treatment Process
This manual summarizes current aeration practices in wastewater treatment, and includes both theoretical and practical guideline for the design and operation of such unit processes. The...
Technological, Hydrological and BMP Basis for Water Quality Criteria and Goals
Water quality criteria and goals may be addressed through at least four means: institution of 1) technology-based controls, 2) best management practice (BMP) based controls, 3) water quality...
Federal Requirements for Storm Water Management Programs
The Water Quality Act has provided the Environmental Protection Agency with the framework for developing a comprehensive storm water management program. The initial phases of the program...
A View from the Middle ? Water Quality Act of 1987: Problems and Possibilites for the Design Professional
Stormwater management has traditionally been viewed as a water quantity concern. The Clean Water Act requirement for future permitting of stormwater discharges will dramatically alter...
A View from the Bottom: Challenges and Prospects
This presentation addresses the Water Quality Act of 1987 (WQA) as it pertains to National Pollutant Discharge Elimination System (NPDES) permits for municipal separate storm sewers. Regulations...
Institutional Aspects of Stormwater Quality Planning
Planning and implementation of programs to control the quality of stormwater runoff in urban areas are carried out within institutional frameworks that directly influence the effectiveness...
Source Control of Oil and Grease in an Urban Area
We explored a variety of techniques to remove oil and grease from urban stormwater runoff. Previous work has shown that relatively high concentrations and substantial mass loadings of...
Advanced Heavy Vehicle Management Systems
This paper describes a program designed to bring to bear emerging technologies in an integrated system to facilitate heavy vehicle management (HVM). One major initiative is the Heavy Vehicle...
Advanced Vehicle Command and Control System
The Advanced Vehicle Command and Control System (AVCCS) is being developed to solve capacity problems on major urban highways using automation and current technology. The objective of...
