Sintering Bricks on the Moon
Sintering of full-scale 'bricks' from lunar soil simulant materials can be accomplished by radiant heating to 1100?C for approximately 2 hours, followed by slow cooling. Small-scale precompaction...
Low Frequency Radio Astronomy from Earth or Lunar Orbit
Acquiring data at low frequencies is complicated by the fact that the ionosphere strongly disturbs the data, especially for high-resolution ground-based telescopes. The most viable observational...
Development of a High Resolution Spectrometer for Measuring the Near-Earth RFI Environment: The First Auto-Correlator in Space
A detailed description of the near-Earth RFI (radio frequency interference environment in the 0.5 - 16.5 MHz range is required before low frequency arrays can be designed and implemented...
An Ultra-Lightweight Advanced Technology Telescope for Space Applications
We propose a new type of telescope designed specifically for space and lunar applications. The optical reflecting surfaces of the telescope are made by replication onto thin ultra-lightweight...
Gravitational Wave Astronomy and the Lunar Ligo Concept
The preliminary proposal (LaFave and Wilson, 1993, 1992) for emplacing a modest LIGO [ Laser interferometer Gravitational Wave Observatory ] system on the Moon using unmanned robotic landers...
Averaging Time and Maximum Speeds in Hurricanes
This paper discuses wind speed data obtained during Hurricane Andrew around Miami International Airport, at six anemometer locations which make up the wind shear warning network. Data...
Practical Application of Tuned Liquid Damper for Tall Buildings
Performance of TLD, based on the full-scale measurement of an actual tall building, is discussed in this paper. Wind induced vibration of the SYP Tower was measured during a gusty day,...
Control of Random Crack Formation in Portland Cement Concrete Pavements
Random crack formation in concrete pavements, which is mainly due to the development of tensile stress caused by temperature-induced volumetric change and shrinkage deformation at early...
Assessing the Impact of Channel Deepening in Delaware Bay Through Numerical Modeling
A three-dimensional numerical hydrodynamic model of Delaware Bay is being developed to assess the impact of deepening the navigation channel from near the mouth of Delaware Bay to the...
Simulated Circulation and Transport in Adjacent Wind-Driven Estuaries in North Carolina
The Pamlico and Neuse River estuaries, in North Carolina, display similar physical characteristics because of their proximity and physiographic setting. Yet, because of channel configuration...
Sensitivity of Great Lakes Forecasting System Nowcasts to Meteorological Fields and Model Parameters
The Great Lakes Forecasting System is being developed by the NOAA Great Lakes Environmental Research Laboratory and Ohio State University. It uses meteorological fields as input to a numerical...
Demonstration of the Wes New York Bight Hydrodynamic Model in Long Island Sound
Recently, a three-dimensional numerical hydrodynamic model of the New York Bight developed by the Waterways Experiment Station was applied to the Long Island Sound subregion, using NOAA's...
Modeling the Seasonal Circulation in Massachusetts Bay
An 18 month simulation of circulation was conducted in Massachusetts Bay, a roughly 35 m deep, 100?50 km embayment on the northeastern shelf of the United States. Using a variant of the...
Instrumented Buoy Network Response to Ocean Swell
The National Data Buoy Center has an extensive network of more than 20 moored buoys along the west coast of North America And in the Eastern North Pacific Ocean. The network ranges from...
Directional Wave Data ? Measurements and Modeling Coast of Florida Erosion and Storm Effects Study
The U.S. Army of Corps of Engineers, Jacksonville District, and the Florida Department of Enviromental Protection are co-sponsors of a study to evaluate the coastal processes along the...
Measured Total Wave Climate of a Small Craft Harbor
Measurements of waves in a small craft harbor were analyzed for the purpose of determining the existing wave climate energy levels causing the excessive agitation of moored small craft...
New Technology in Coastal Wave Monitoring
The Coastal Data Informational Program (CDIP) is an extensive network for monitoring waves along the Pacific coastlines of the US. The system has evolved substantially since its inception...
Nonlinear Decomposition of a 2-D Wave Field
Based on an understanding of nonlinear wave interaction in dual component wave, a new numerical scheme allowing for hybrid wave-mode modeling has been developed. in the hybrid wave-mode...
NDBC Wave Data?Current and Planned
The National Data Buoy Center (NDBC) of the National Weather Service (NWS), operates a large number of buoy and fixed-platform environmental data reporting stations in geographical areas...
Design of an In-Situ Directional Wave Gage for One Year Deployments
This paper describes the design and implementation of a new in-situ, directional wave gage that records hourly directional spectra continuously during a 13-month deployment period. If...
