Typical acoustic materials rely on embedded continuous mass layer to attenuate low frequency sound. Energy from low frequency sound is not effectively mitigated with these materials unless a substantial amount of mass is added. Thus, standard materials for low frequency noise control tend to be heavy, expensive and difficult to install. A new technology is being developed that utilizes optimized ...

Modern control theory offers mathematically rigorous and powerful solutions to many dynamic systems. Its limitations are that the classes of dynamic systems covered by the theory are limited to linear systems or certain well-structured nonlinear systems, and the adaptation of the controllers are often slow if the controller parameters are far away from their desired values. On the other hand, the ...

Friction Stir Processing (FSP) has been demonstrated to generate refined microstructures, resulting in improved material properties. This has several areas of application. First, FSP can enhance the formability of the particular alloy of interest. This is especially important for the superplastic forming process, where the use of FSP can be used to create superplastic behavior at high strain r ...

The Navy needs to design new ships capable of accomplishing complex missions at a reduced cost. In order to enable US military response to threats around the world new ships must be designed with improved operational abilities and with capabilities to integrate with other ships and platforms for maximum operational flexibility. New enabling technology is needed for performing systematic design f ...

Window materials are an essential component of some advanced propulsion concepts which require high pressures, high temperatures, low energy losses, and low weights. Window materials must possess a combination of properties such as high mechanical strength, high melting point, high transparency, low density, and good resistance to the operating environment. CeraNova proposes the development of f ...

Emerging drug resistance in infectious threats poses a health risk for deployed forces. The primary objective of the Phase I effort was to enable the development of a sustainable drug discovery effort to continually generate lead compounds for discovery and derivative synthesis. Successful completion of Phase I demonstrated the utilization of a novel source of lead compounds, validation of two hi ...

In this STTR project, Boston Applied Technologies, Inc. (BATi), teaming up with Prof. Di Bartolo’s group at Boston College, aims at developing a large size (300 mm x 300 mm) updatable 3D display with photorefractive polymers for battlefield and command and control applications. The proposed 3D display system features fast response (feasible to video-rate), high diffraction efficiency, and relati ...

Microfibrous Entrapped Catalysts (MFEC) are proposed for detailed analysis to determine their potential to meet future Navy fuel needs by means of highly selective Fischer Tropsch Synthesis (FTS). MFEC are comprised of small grains of supported catalysts (ca. 10-200 micron diameter) entrapped within sinter-locked networks of micron diameter metal fibers. Metal fibers comprise only 5-10 vol% of the ...

Warfighters are increasingly relying on technology equipment to ensure safety, mission effectiveness, and situational awareness. This equipment increases the capabilities of warfighters but also adds to their weight burden. This excess load could cause significant stress on the musculoskeletal system and lead to physiological deficits. The overall objective of the proposed project is to develop a ...

The overall objective of this STTR project is to develop a comprehensive CAD environment for design and optimization of antennas and arrays on complex platforms such as topsides of naval surface combatants. EMAG Technologies Inc. has teamed up with the University of Michigan to develop a novel solution for genetic algorithm based placement of antennas on such platforms. The proposed solution invol ...
