Gallium Nitride (GaN) substrates are ideal materials for fabrication of high-power and high-frequency devices based on III-V materials. The current state-of-the-art Chemical Mechanical Polishing (CMP) methods are plagued by several challenges, including, surface charge affects due to surface contamination, and sub-surface damages, which can limit the quality of III-V devices. Furthermore, there is ...

Structured Materials Industries, Inc. (SMI), working with others have demonstrated functioning fundamental memristor material technology. In this program, working with our University partner and end use collaborators, we propose to provide an infrastructure for making memristor materials at production scales, expand/refine the known memristor materials, provide samples of the produced memristor ma ...

Frequency Agile Laser sensor has shown great promise in standoff detection of chemical and biological agents in the long wave infrared (LWIR) portion of the spectrum through several field trials in recent years. The fact that it is now possible to perform

The real-time implementation of controls in nonlinear systems remains one of the great challenges in applying advanced control technology. Often, linearization around a set point is the only practical approach, and many controllers implemented in hardware systems are simple PID feedback mechanisms. To apply Pontryagin’s principle or Bellman’s equation using conventional hardware and algorith ...

We propose to construct a deception detection system which will exploit scaffolding provided by a collection of largely domain-independent deception detection heuristics. These heuristics, integrated through a novel evidential reasoning system, will provide the proposed system, called Skeptic, with a significant advantage over purely inductive methods by allowing it to exploit the adversarial natu ...

A military without good leadership is a mob. Identification, preparation, guidance and mentoring of potential leaders are critical functions across all services. Leadership training and support can be substantially improved by refinement of theories and models on what constitutes good leadership, and what enables individual to be effective leaders. DoD needs better models of how leaders learn, ...

Free electron lasers (FEL) made from Nb cavities offer high performance, but they are complex, bulky, and expensive. For Navy FEL applications, where footprint, power consumption, and cost are severely constrained and reliability is of great importance there is a critical need for an alternative to Nb. MgB2 is a recently discovered superconductor with a high critical temperature and critical field ...

A rapid prototyping simulation for the Autonomous Rotorcraft Land & Take-Off (ARLTO) system will be developed to analyze and evolve requirements for the landing and take-off of a Rotary-wing Autonomous Air Vehicle (RAAV) from unprepared terrain. The simulation is based upon the Task-Pilot-Vehicle modeling system and features a UH-60 configured with a Sliding Mode Control (SCM) inner loop closure. ...

The Air Force has a strategic need for a fuel source that is renewable (and which does not rely on foreign petroleum sources). Several approaches to a renewable fuel source have been investigated; with “artificial photosynthesis” being one example. At its core, the photosynthesis reaction is a photoinduced charge separation reaction with light being concentrated by antenna complexes onto a c ...

ABSTRACT: A system that operates at room temperature and that could scan for concealed weapons from standoff distances of >10 m would be a tremendous asset for US military homeland security personnel worldwide. THz imaging can, potentially, be used for this application, but it requires the development of a new class of THz detectors whereby the signal to noise ratios are improved significantly. ...
