Predicting the high Reynolds number viscous turbulent flow around realistic aircraft, rotorcraft and ship geometries with CFD is time consuming and computationally expensive, with the number of cells required to resolve the flow driving the computational cost. Even with modern CFD methods, the cost of adequately resolved solutions is prohibitive for most engineering tasks. The team of Continuum Dy ...

Advances in the fields of real-time computer graphics, behavioral animation and artificial intelligence are enabling creation of realistic 3D Virtual Environments (VE) in which participants can acquire skills that are normally too costly, dangerous orotherwise impossible to achieve using traditional training methods. The effectiveness of such training applications is currently limited when requiri ...

Our goal in this Phase II effort is to construct and test a compact, robust testbed for generating laser-cooled strontium atoms on a mobile platform. The focus of the Phase I effort was designing and fabricating an ovenized strontium source that also serves as a 2D+ MOT cell. In Phase II, we will integrate the strontium source into an all-glass-and-silicon vacuum system maintained by a miniature i ...

DeveloSoft proposes to use its considerable carrier automation experience to investigate three main approaches for gesture recognition. First, we will evaluate either Measurand ShapeTape or micro-accelerometers for direct measurement of arm and handpositions. Second, we will investigate an imaging approach using LEDs or reflective tape... both with specially tuned optics and frequencies which wo ...

The Navy is interested in developing hybrid superconducting power transmission cables that would carry at least 5 kA of current and have a current density of at least 35 MA/m2. The cable should be able to carry 30 % of the rated current even when the superconducting cable fails. We propose to develop a hybrid superconducting cable, based on CORC cables, which potentially have a current density of ...

The proposed work seeks to establish electric field sensor performance goals and study state of the art electro-optic and nitrogen vacancy diamond electric field sensors.

A multi-scale/multi-physics integrated tool will be developed to virtually and qualitatively predict the manufacturing defects in structural thermoset polymer composites through a first-principles based approach. The chemo- and thermo- mechanical properties of the thermoset resin during the autoclave process will be characterized with a reactive force field full atomistic and coarse-grained molecu ...

The emerging HR environment in the Navy presents a variety of challenging problems that can be addressed with the aid of operations research methodologies. Optimization modeling and solution techniques along with simulation hold particular promise asmodern approaches in this area. In this project we represent these challenges by presenting a significant human resource problem associated with DDX, ...

In order to provide performance capabilities well above those of individual independent sensors, future naval sensors will be networked throughout a battle group based on the real time knowledge of the precise relative distances and relative velocities between ships. One possible means to obtain and monitor such position and velocity in real time is laser range finding, which must be eye safe espe ...

A large majority of aircraft shot down over the past three decades have been lost to infrared (IR)-guided anti-aircraft missiles. One of the major factors affecting final development and deployment of an IR CounterMeasure (IRCM) system on Naval aircraftis the high cost of the system. This proposal seeks to reduce the cost of the detector portion of the IRCM system. Silicon technology offers a p ...
