The integrated photogrammetric mapping system flown on the last three Apollo lunar missions (15, 16, and 17) in the early 1970s incorporated a Metric (mapping) Camera, a high-resolution Panoramic Camera, and a star camera and laser altimeter to provi

Carbonaceous asteroids, such as (101955) Bennu, preserve material from the early Solar System, including volatile compounds and organic molecules. We report spacecraft imaging and spectral data collected during and after retrieval of a sample from Be

A technique by which to achieve noise control in a dynamic system, referred to herein as a master dynamic system, is to couple it to another, an adjunct dynamic system. The resulting induced noise control is defined in terms of the ratio of the energ

In two recent papers, the induced loss factor is determined via the modification to the loss factor in the linear impedance of a master oscillator caused by its coupling to a set of satellite oscillators. A loss factor is basically an energetic quant

This paper addresses the problem of scheduling randomly arriving tasks of different types at a diversified service system. Servers at such a system differ in that each may specialize in one task type, but can also perform others perhaps less rapidly

The design of a wide frequency band neutralizer, vibration absorber and/or structural fuzzy, in the form of multiple-sprung masses, is extensively reported in the open literature. The action of the device is reported in terms of the joint point imped

The overall gain is defined as the ratio of the stored energy in the isolated master harmonic oscillator to that in the coupled one. This gain is composed of two distinct factors: The first factor, the external input power gain, relates to the ratio

When, in a given frequency band, the magnitude of the line impedance of the ribs approaches and exceeds the line impedance of a moderately damped shell, to which the ribs are attached, a stop band emerges. This stop band need not coincide with any of
