White River Technologies, Inc. (WRT) presents this proposal, "Acoustically/Vibrationally Enhanced High Frequency Electromagnetic Detector for Buried Landmines".The primary goal of the proposed effort is to develop a prototype vibrationally-enhanced detection system capable of landmine and IED detection and discrimination with performance greater than conventional GPR sensors.The main sensing compo ...

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 ...

This Small Business Technology Transfer (STTR) Phase I effort will demonstrate the feasibility of a novel passively adaptive shock and vibration isolating buffer system for the US Navys combatant craft. The proposed approach does not rely on conventional passive, semi-active or active spring-damper systems. The buffer system will provide energy damping via a liquid spring buffer and eddy current d ...

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 ...

The purpose of this proposal is to additively manufacture (AM) smart structures with embedded electronics such as sensors, accelerometers, antennas, etc. The goal of these smart structures will be to enhance the effectiveness and survivability of the Armys ground systems. The use of additive manufacturing smart structures provides flexibility in the materials used and the functionality of the elec ...

Nickel super alloys, such as Inconel®, are leading candidates for fossil energy-based power production components due to their resilience in extreme environments. A significant technical roadblock to the implementation of nickel-based power plant systems is the inability to produce large-scale components in a cost competitive manner. We will address the problem of manufacturing large, low-cost su ...

Karagozian & Case, Inc. (K&C) and the Georgia Institute of Technology (Georgia Tech) will develop a re-usable, cost-effective, and accurate dynamic characterization methodology capable of measuring the dynamic material properties of various materials of interest under very high strain rates. Materials property data for various ductile materials (e.g., steel and aluminum) are required as input to 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 ...

Gray cast iron piping is the most common pipe material in North America. Based on the high carbon content, graphitic needles or flakes are a common feature in these alloys. As a result, these areas of super-saturated carbon will consistently establish galvanic attack of the adjacent iron matrix, especially when in the presence of most ionic liquids. The localized galvanic potentials create microsc ...

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 ...
