A proposed acoustic pattern recognition system will be based around an array of acoustic sensors to allow localization of sound events and cancellation of background noise. The number of sensors could be adjusted to vary the coverage area depending on the site. The measured signals will provide the input to a sophisticated signal processing algorithm that will separate the acoustic signals into ...

The proposed effort is to evaluate the feasibility of a W-band sheet-beam vacuum electronic device that can provide up to 1 kW of peak RF power at a minimum efficiency of 20%. Key elements of this effort are on the generation and transport of the sheet beam and its interaction with the RF circuit. The potential of employing a depressed collector to improve overall efficiency will also be investiga ...

Modern military operations increasingly require decision-makers to reason predicatively about adversary actions and the battlespace environment – a task made more challenging due to meta-information (i.e., qualities of information such as uncertainty or staleness). Understanding the role of meta-information in reasoning about intelligence and developing methods for effectively portraying it ha ...

GES proposes to develop the electrochemical alkaline hydrogen peroxide (HP) generator and integrate it with neutralization and evaporation subsystems to form a prototype HP vapor generator for decontamination of enclosed areas. The focus of GES’s involvement shall be the advancement of our electrolyzer technology and the evaluation of various evaporation schemes. USC will focus on modeling the c ...

Durability is the effect of time dependant processes, including fatigue, creep, moisture absorption, thermal-oxidation, abrasion, chemical reactions and physical ageing on mechanical properties. The ability to predict accurately the durability of composite materials and structures is critical to successfully designing for longevity. The existence of models alone is not sufficient; practical soft ...

The purpose of this project is to demonstrate the effectiveness of using an innovative deposition process for making Sm2Fe17Nx/á-Fe16N2 magnetic materials in bulk quantities. In addition, exchange-coupled nanostructured composites of these materials will be produced. The advantage of this process is that it allows precise control over the deposition ions so that the morphology of the materials ca ...

The Army has an obvious and immediate need for greater exploration of small molecules in the search for novel anti-malarial drugs. The innovative techniques offered in this proposal utilize methods of iterated automated fragment assembly coupled with an intelligent compound screening tool to facilitate scientific advancement. The resulting computational methods can increase the rate and exploratio ...

Lattice Block Structures are innovative, periodic cellular materials whose combination of affordability, low relative density, and substantial strength represents a significant advance in the state-of-the-art of engineered structural materials. Lattice Block Structures in particular have superior kinetic energy absorbing ability that stems from the collapsibility of the internal cells. As a result ...

At present, turbine NDE is typically a time consuming collection of inspections that includes manual testing of holes and channels for blockages, multiple flow tests and various inspection technologies such as ultrasound, eddy current and radiography. Thermography has also become a widely method used to perform various inspections. However, many of thermographic inspections require different equ ...

The main goal of the proposed research is to develop a material with a high modulus ratio (Ez / Ex = 105 ) by the end of Phase II. This material is ideally suited for use in morphing aircraft that require large shear strains of the skin, while limiting out-of-plane pillowing at the same time. The major effort during the beginning of the program will be to characterize Shape Memory and Electroactiv ...
