Seismic Stability Analysis of Landfill
The failure mechanism of a waste containment system is not well understood due to the complexity and the heterogeneity of the system. The recent slope failure of the Kettleman Hills waste...

Directions for Lunar Construction: A Derivation of Requirements from a Construction Scenario Analysis
This paper provides an initial trade-off study among several lunar construction options available to the Space Exploration Initiative. The relative time effectiveness of Extra-Vehicular...

Environmental Aspects of Lunar Helium-3 Mining
Three potential detrimental effects of lunar ³He mining have been identified; visual changes, atmospheric contamination, and solid waste disposal....

Steady State Composition with Low Fe?⁺ Concentrations for Efficient O₂ Production by Magma Electrolysis of Lunar Soils
Parameters are estimated for a hypothetical, well stirred, continuous-feed electrolytic cell that converts 20% of a lunar soil feedstock to O₂ gas,...

The Initial Exploration of Mars: Rationale for a Return Mission to Chryse Planitia and the Viking 1 Lander
The concepts behind planning a landing site on Mars are discussed. Based on the engineering constraints and the scientific objectives which will likely be imposed on the first few missions...

Regenerative Life Support Technology Challenges for the Space Exploration Initiative
Regenerative life support systems have been identified as one of the critical enabling technologies for future human exploration of space. This discipline encompasses processes and subsystems...

System Concepts for a Series of Lunar Optical Telescopes
The Lunar Telescope Working Group of the Marshall Space Flight Center (MSFC), NASA, has conducted conceptual studies of an evolutionary family of UV/optical/IR telescopes to be based on...

The New Munich Airport?Planning, Construction and Opening of a New International Turnstile Airport in Europe
The new Munich airport that began operations just recently dates back to the mid-1950. The paper discusses the general expansion plan which includes site selection; runway system planning;...

City and County of Denver Approach to Management Requirements
Construction of large infrastructure projects has become increasingly rare since the 1960's. In fact, America has not built a new airport since 1974. While sparse funding is certainly...

Management of Design
Denver's new airport uses the services of over 80 separate design firms. The existing airport, Stapleton, could not be expanded to meet the forecasted demand of 1,200,000 operations with...

Traffic Data Collection: What Really Needs to be Done?
The collection of 'existing' traffic data such as the 24-hour counts, turning movement counts, driveway volumes, and vehicle classification counts near the proposed project site becomes...

A Guideline for Determining Minimum Threshold Requiring Traffic Impact Studies
Over the years, a number of localities have developed and adopted some form of traffic impact assessment (TIA) guidelines. As part of this study, an informal survey conducted showed that...

Analyzing Fast-Food Drive-Up Window Site Impacts
Peak-period queueing at a fast-food restaurant drive-up window was observed. The study found that queueing behavior equations based on random arrivals and service times overestimated the...

Access Control to Projects Via Raised Islands
When addressing driveway maneuvers at a new development, alleged ailments Must be quantified before drafting a cure. If a problem is anticipated, alternative solutions should be investigated,...

Site Impact Analysis Using the Tranplan Computer Model
As the cost of infrastructure improvements continue to spiral upward local and state governments are finding it more difficult to provide for increases in traffic volumes due to growth...

Using Computer Models in Site Impact Assessment
Use of comprehensive large area traffic models (citywide or regional) in site traffic impact assessment can greatly aid certain elements of the analysis, but may be inappropriate for other...

Computerized Transportation Planning Models for Site Impact Analysis: Precision or Complexity?
Computer based travel forecasting models are now being widely used in the analysis of the traffic impacts of proposed developments. They are commonly used to identify improvements needed...

Traffic Impact Studies for Marriott Corporation International Headquarters
This paper describes the steps taken in developing innovative traffic-related solutions to obtain approval for the Marriott Corporation International Headquarters site, which is planned...

Traffic Impact Assessment for Snow Disposal Facilities?Extended Abstract
Snow disposal facilities perform an integral role in the maintenance programs of many municipalities in canada and other northern countries. The most popular type of snow disposal facility...

Solid Waste Travel Demand Model Using GIS and Simulation for Evaluating Site Impacts
This study accomplishes two objectives: (1) develops a model to forecast future household travel demands for a given solid waste site in Fairbanks, Alaska and (2) develops precursory techniques...
