Logistics Support of Space Facilities
The logistic support of space facilities is described, with especial attention given to the problem of sizing the inventory of ready spares kept at the space facility. Where possible,...
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....
Indirect Solar Loading of Waste Heat Radiators
Waste heat from space based power systems must ultimately be radiated away into space. The local topology around the radiators must be considered from two standpoints: the scattering of...
21st Century Astronomical Observatories on the Moon
The advantages and disadvantages of building astronomical observatories on the Moon are described. In many ways, the Moon is a superior environment for astronomy to that of the Earth's...
Fuzzy Set Evaluation of Lunar Structures
The design, construction, and performance assessment of lunar structures are unprecedented in nature. Experts in these areas tend to use qualitative measures when expressing their judgment....

Unconventional Rubble-Mound Breakwaters
This book presents a state-of-the-art review of the design, analysis, hydraulic model testing, and prototype experience of a new class of coastal structures that produce economical designs...
Earthquake Engineering and Soil Dynamics II?Recent Advances in Ground-Motion Evaluation
Ground-motion determination for analysis and design of engineering structures is a shared, interdisciplinary task involving geologists, seismologists, geophysicists, geotechnical engineers,...
Lessons from Dam Incidents. US-II
The purpose of this report is to present available data to the profession regarding failures, accidents, and major repairs at dams in the United States. Data is analyzed with respect to...
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...
Changing Requirements
There are three sections to the presentation. First, a discussion of the changing environment of highway transportation - what are the factors and variables that are changing in the world...
How Uncle Sam Values Mortality Risk Reductions
This paper reviews the policies, methods and 'value-of-statistical-life' (VSL) estimates used by several federal agencies to assess the economic efficiency of...
Highway Safety in 2010: Compromising Among Values
A prediction is made of the highway safety development, based on analysis of current crash data and expected improvements in highway safety. The paper includes discussions of travel mileage...
Seismic Reliability of Hierarchical Lifeline Systems
The problem to be considered here is the vulnerability and reliability of a functionally as well as physically hierarchical lifeline system. Most major lifeline systems have this feature;...
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....
Zapping Hazwastes
Electromagnetic energy, applied in situ, successfully removes contaminants entrapped in soil by vaporizing them. Recent test using radio frequency have successfully removed up to 99% of...
What really happened at L'Ambiance Plaza
Even though the National Bureau of Standards has issued its report on the probable cause of failure in the collapse of the L'Ambiance Plaza. there is room for doubt as to...
Real World Analysis
The structural concepts, seismic analysis and design of five recent highrise structures is presented in this paper. The paper deals with the problem of multistory buildings having Structural...
Computer Assisted Mistakes
The proliferation of computer usage by design engineers will continue to generate change in practice. It will affect the process and production of design. It will affect the relationships...
Concrete Pavement Rehabilitation Research Findings
