Flow in a Model Symmetric Bifurcation
Flow through bifurcations is of particular interst to the field of hemodynamics and respiration dynamics. In this paper flow through a model symmetric bifurcation is studied experimentally...
Measuring Vibration in an Advanced Composite Beam with Localized Internal Fiber-Optic Strain Sensors
Two optical fibers embedded with different configurations were used separately as strain sensors to measure the natural frequencies and modal amplitudes of a cantilevered graphite/bismaleimide...
A New Era in Space Operations
The United States has embarked on a bold new course in space. We are in the process of deploying global missile defenses which promises to help realize an extended era of international...
NASA's Future Plans for Space Astronomy and Astrophysics
This paper presents NASA's plans for future space astronomy and astrophysics through the first decade of the next century. Discussed will be specific missions and mission concepts, as...
The Proposed NASA Lunar-Based Astronomical Observatories
The goals of the Space Exploration Initiative are a manned return to the Moon, a permanent lunar outpost and then a manned expedition to Mars. This presents an opportunity to construct...
Some Considerations for Instrumentation for a Lunar-Based Solar Observatory
Outstanding problems in solar physics, observational trends and directions of instrumental development in solar astronomy are discussed briefly. These lead to the specification of observational...
SALSA: A Lunar Submillimeter-Wavelength Array
A conceptual design is described for a lunar submillimeter-wavelength interferometer called SALSA, a Synthesis Array for Lunar Submillimeter Astronomy. The intent is to describe SALSA...
Low Frequency Astronomy from Lunar Orbit
The Radio Astronomy Explorer satellite verified that the far-side of the Moon is well shielded from manmade and natural Earth-based interference at frequencies below 30 MHz. Above a few...
Plot-scale Field Experiment of Surface Hydrologic Processes with EOS Implications
Plot-scale hydrologic field studies were initiated at NASA Marshall Space Flight Center to a) investigate the spatial and temporal variability of surface and subsurface hydrologic processes,...
The Wide-Angle Optoelectronic Stereo Scanner WAOSS for the Soviet Mars 94/96 Missions
The Wide-Angle Optoelectronic Stereo Scanner WAOSS is anticipated for the Soviet Mars 94/96 missions. Starting from the tasks of WAOSS as a part of the TV complex ARGUS, the paper describes...
Lunar Farside, Mars Polar Cap, and Mercury Polar Cap Neutrino Experiments
Neutrino detection offers unusual Civil Engineering challenges for the inner Solar System, including: outposts and permanent bases on the Moon, a novel development within the polar caps...
In-Flight Calibration of Mass Spectrometer
A new device for in-flight calibration of mass spectrometer is presented. At a ground station command the calibrator introduces a constant and reproducible amount of deuterium into the...
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...
The Foundation for a Successful Traffic Impact Analysis
Both governmental agencies and private developers use the information developed in a traffic impact analysis (TIA).Traffic Impact Studies can be an important tool in efforts to maintain...
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...
Comparison of Delay and ICU Analyses?Case Study
Traffic Management Initiative was a petition-based referendum that sought to limit traffic impacts of proposed or planned development through the use of more stringent transportation planning...
ICU?A Method of Analyzing Signalized Intersections
There is a need for decision makers, developers and the public to understand the potential traffic impacts of site development. Signalized intersection operations are a primary indicator...
Trends in Published ITE Trip Generation Rates
Since 1976...
Trip Generation Rates, a Historical Look
This paper compares the 1990 weighted average trip generation rates of military bases, shopping malls, universities, airports, and hospitals for San Antonio-Bexar County and Amarillo,...
