A Wax-Coupled Borehole Seismic Detector for High-Resolution Measurements
A triaxial borehole seismic detector was developed for high-resolution measurements at frequencies up to 2,000 Hz. Applications for this detector include three-component shallow reverse...

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...

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...

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...

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...
