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, ...

The research objective is to develop Modeling and Simulation (M&S) tools to accurately predict the performance of new state-of-the-art material systems as protection for high value missiles deployed in their launchers or canisters. The focus is on adapting multi-layered novel and non-traditional material technologies to improve protection against penetration and fragment impacts, focused detonatio ...

The research objective is to develop a fully functional computational method for prediction of the after-burning effect of different fuels in a wide range of temperature, pressure, and turbulence regimes. Achievement of the objective requires understanding and modeling of key phenomena including (a) post-detonation response of the fuels, (b) near-field coupling of detonation products with particul ...

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. ...

TSC and Purdue University will demonstrate a lab prototype of software and hardware capable of doing high speed monitoring of a Lithium-Ion cell. This monitoring needs to be specifically designed to predict failures. When a predictive failure is indicated a defensive countermeasure needs to be implemented. Our specific project goals are to: 1) Select a Lithium-Ion battery that consists of multiple ...
