Adroit Systems, Inc. will develop a Pulse Detonation Synthesis (PDS) process to manufacture ceramic powders from gas-powder reactant mixtures more efficiently and inexpensively than current methods. A high combustion rate and simple design make the PDS system capable of mass producing these powders, which are used as raw materials for high-temperature, high-performance ceramics and ceramic composi ...

This Phase I project has two primary objectives. The first objective is to evaluate the feasibility of a fully ion implanted fabrication process based on the heterodimensional 2-D MESFET. The new device, the 2-D JFET, will have p+ ion implanted sidegates which laterally modulate a thin, highly doped n-type conducting channel. The 2-D JFET should have excellent high speed, low power characteristics ...

As an alternative to holographic laser radar, AMPS will develop a 3-D imaging concept that collects far-field intensity speckle patterns. This kind of measurement greatly relaxes the tolerances on vibration and coherence length. However, phase retrieval will be required to retrieve a 3-D image. Phase retrieval algorithms typically utilize some type of prior knowledge about the object. In industria ...

The nuclear weapons community has traditionally focused on the next generation or level of weapon capability complimented by gathering and analysis of actual test data. Now, with the cessation of actual weapons testing, there is an increased need to use the actual test data in modeling techniques to better understand the phenomenology and potential effects of nuclear weapons. The first phase of ...

DEVELOPMENT OF AN INNOVATIVE AND ECONOMICAL EXPERIMENTAL METHOD IS PROPOSED WHICH CAN PROVIDE THE BASIC BEHAVIOR DATA NECESSARY TO MEET THE DNA OBJECTIVE OF PROVIDING ADEQUATE ANALYSIS, DESIGN AND ASSESSMENT METHODS FOR MINIMALLY HARDENED TUNNELS. THIS DEVELOPMENT IS ACCOMPANIED BY ANALYSIS CAPABLE OF REPRESENTING THE COMPLEX INELASTIC MATERIAL BEHAVIOR OF THE ROCK MASS AND OF REPRESENTING SIMPLE ...

Turbulence of gas flows by its very nature is one of the most difficult things to model and measure. We propose to develop a new way of measuring the turbulence and to compare these measurements to predictions using the k-epsilon model. Typical measurements, in the past, use smoke, Schlierin or shadow graph techniques to visually infer turbulence characteristics. These features are either motio ...
