Molecular nanotechnology has matured in the last thirty-nine years from the germ of an idea by a Nobel Laureate physicist to a rapidly growing international research site with more than $1 billion dollars in annual investment. ...

Interferometric optical fiber sensors have proved many orders of magnitude more sensitive than their electrical counterparts, but they suffer from limitations in signal demodulation caused by phase ...

A probabilistic risk assessment (PRA) for the discharge of excessive nitrogen from nonpoint sources (NPSs) to a stream was performed for a small agricultural watershed in northern Virginia. Risk, by definition, is the ...

The conveyance of payloads by construction cranes generates pendulations of the payload. This research provides a critical design parameter for the development of a device that aids in reduction of these pendulations. Previous ...

This thesis concerns itself with a finite element model of nonproportional viscoelastic damping and its subsequent reduction. The Golla-Hughes-McTavish viscoelastic finite element has been shown to be an effective tool ...

THE LEACHED LAYER FORMED ON WOLLASTONITE IN AN ACID ENVIRONMENT Erich J. Weissbart (ABSTRACT) Experiments were carried out in a fixed-bed external recycle mixed flow reactor to measure the rate of dissolution ...

The purpose of the present study was to tease apart the paralinguistic from the linguistic aspects of infants' perception of infant-directed (ID) speech. Several studies have shown that infants beginning at a few days ...

ABSTRACT The low temperature phase behavior of the system H2O-NaCl-FeCl2 was examined using synthetic fluid inclusions. Experiments were conducted along the 5 wt% NaCl (relative to the total solution) pseudobinary, with ...

<p>The maximum von Mises stress is calculated for solid finite element models of splined shafts with straight-sided teeth. One spline shaft is stepped with larger diameter section containing spline teeth and the smaller ...

A key purpose of federal job training policy is to ensure that the workforce has the skills necessary to obtain and retain gainful employment. The purpose of this study was to describe and compare key elements of ...
