The Levitation of Lunar Dust Via Electrostatic Forces
Apollo and Surveyor photographs revealed an unexpected lunar phenomenon that has come to be known as the 'horizon glow'. During lunar sunrise and sunset, a line of light was visible above...
Lunar ISRU: An Evolutionary Approach
The goal of this paper is to provide the reader with a vision of the individual steps required to bring ISRU from the current technological readiness level of lab experimentation, to large...
Lunar Oxygen Production - A Maturing Technology
Research on oxygen production from lunar rock and soil has made significant progress in the past two years. An extensive series of experiments on natural and synthetic analogs has concentrated...
Oxygen Generation from Synthetic Moon Soil Using a Plasma Reactor
A series of experiments were performed to evaluate the potential for generating oxygen from silica powder, alumina powder and a synthetic moon soil powder. A non-transferred arc plasma...
Oxygen from Lunar Soil via Fluorination
This paper considers oxygen extraction from lunar soil via fluorination, for reasons of its high effectivity of oxygen release from most silicates. In addition to theoretical investigations,...
Estimation of Structural Damping of Buildings
The full-scale data on damping ratio are collected from 77 buildings within Japan. Almost all data are obtained from vibrations with a very small amplitude such as microtremor, man-power...
Optimization of the Design and Operation of Soil Vapor Extraction Systems
Volatile organic compounds (VOC's) immobilized within the soil unsaturated zone constitute a significant source of groundwater contamination. Soil vapor extraction systems (SVES's), which...
Procedures for Evaluating the Effects of Sedimentation on Flood Hazards in Urbanized Areas in the Southwestern U.S.
Urbanization of watersheds in the arid Southwestern U.S. creates problems for resource agencies and design engineers. Traditional analytical techniques that are generally applicable to...
Public Involvement and Participation: Planning Imperatives for the Coming Century
The literature has identified three types of responses to natural resources planning and management efforts in the United States. The first focused upon the more effective use of existing...
San Diego County Water Authority's Emergency Storage Project Supplying Water During Natural Disasters
The San Diego County Water Authority (Authority) is developing the Emergency Storage Project (ESP) to improve the dependability of the County's water supplies during a natural disaster...
Development of an Expert System to Identify Hazardous Highway Spots
The paper describes the development of an expert system within a geographic information system to identify high-hazard spots in a highway network. The philosophy guiding expert system...
Using Pen Computers in Post-Disaster Insurance Claim Settlements
The advanced use of pen computers for insurance claim damage assessment and settlement are explored. The advantages of implementing such a paperless approach to insurance claim settlements...
Uncertainty and Time Preference in Shore Protection
From a review of economic, psychologic, and geographic literature, three points of criticism of the economic model of choice are 1) when faced with losses, individuals tend not to be averse...
Risk Management Strategies for Natural, Manmade, and Technological Hazards
The paper summarizes the fourth session of the conference which discussed risk assessment approaches in bio/chemical hazards; specific studies on people's behavior and views of natural...
The Performance of Unconfined Hollow Fiber Membranes as Pipe Flow and Mixed Flow Aerators
