ABSTRACT: Feature extraction and target recognition suffer from a lack of a reliable model for both exploitable target features and the electromagnetic signature they possess. Signature data are often hard to interpret and invert to recover the target robustly. Bayesian learning approaches to statistical pattern recognition are based on the use of training sets of inputs and outputs, a data mode ...

This proposal is for the use of state-of-the-art computer wargames to be used in the research on the impact and optimal use of unmanned aerial vehicles (UAVs) in realistic combat scenarios. High fidelity, historically calibrated wargames ranging from sub-tactical ground-centric game engines through operational, strategic, air campaign, and naval-centric game engines will be used to address the fu ...

Ultrasound is a therapeutic modality which has been used clinically for 60 years, but has been limited in practice by the complexity of the technology. Recent research has allowed for the development of a portable, wearable, long duration, low intensity therapeutic ultrasound system. The system is powered by battery, and can be applied by a user to deliver up

ABSTRACT: Current and projected limitations on the maximum power from a high power single mode fiber laser amplifier impose architectural limitations on a high power phased array laser weapon system. Prior studies strongly indicate that when faced with this limitation the optimal approach is (to borrow the term for Paul McManamon) a Phased Array of Phased Arrays (PAPA) geometry wherein large(r) ...

The overall goal of the proposed research program is to design a ruggedized imaging system capable of visualization and analysis of the particle field and product gases in a multiphase blast. This will be accomplished by combining kHz-MHz-rate burst-mode laser technology with tomographic particle image velocimetry (PIV) and new nonlinear particle tracking methods to resolve dense particle fields. ...

The objective of this Phase I project is to evaluate the use of novel Laser Induced Surface Improvement (LISI) techniques to provide surface modification to substrate materials which will provide superior wear resistance in extreme conditions. The specific application of interest is the hypersonic metal-to-metal contact that occurs at high speed test track facilities that can and has lead to catas ...

Training can now delivered on a large scale through platforms, but must be engaging to be effectively utilized. Key to providing training that makes a difference in the field is an understanding of how to induce high levels or engagement during learning, and the ability to objectively assess engagement in real-time so that interventions can be tailored during training to optimize engagement and m ...

Improved temperature measurements of thermal barrier coating (TBC) components are needed for gas turbine research and development.Imaging pyrometry systems are preferred because they are non-contact and can measure the complex spatial temperature distribution on components.Measurement in the long-wave infrared (LWIR) band is required for accurate temperature measurements of modern TBCs.Fiber coupl ...

We are proposing to develop a highly parallel, rapid prototyping system for the manufacture of microfluidic devices. In this phase II proposal we will build a complete system for making such devices for continued research on fieldable microfluidic systems for use in the military, and in hospitals. The project will also allow manufacturing in widely different materials, and structures, without an ...

Designing an efficient and effective film cooling system to protect critical components of modern rocket engines requires a significant number of problems and challenges to be addressed. Complicating the already difficult hydrodynamic challenges, thermal and/or catalytic cracking of hydrocarbon fuels is always accompanied with coke formation. Coke deposits on combustor and nozzle walls reduce heat ...
