Statistical Energy Analysis (SEA)is currently used to predict high-frequency airborne and structureborne noise and vibration for ships, aircraft, aerospace systems, and automobiles, while finite element analysis (FEA) is used for low-frequencies. A mid-frequency region exists where neither technique gives accurate predictions. The study being proposed will develop modeling procedures that a ...

This Phase I proposal is to develop methods to couple a numerical three-dimensional groundwater contaminant fate and transport model with Monte Carlo probabilistic risk assessment methods in order to allow selection of remedial criteria based on reasonable estimates of risk to humans and the environment. The market will be searched for the most effective and available three-dimensional numerical ...

Assessing mechanical properties of the snow pack is essential to provide ground truth for remote sensing and to predict the propensity of snow to slide and its ability to support platforms. Currently, the most common method to do this assessment is to dig a number of large holes in the field. CAPACITEC thus proposes to develop a field penetration probe for measuring profiles of snow density, wet ...

A new family of surface-active organic compounds is proposed for formulating multi-purpose vapor phase corrosion inhibitors (VCI's). The proposed research explores the feasibility of applying state-of-the-art surface science with the concepts of molecular simulation and molecular self assembly to produce a new class of corrosion inhibitors. The ultimate objective is to develop a family of VCI's ...

Improved magnetic and electromagnetic sensors covering a wide range of frequencies, 0 to 10kHz, and with extremely high sensitivity are proposed for broad area detection and characterization of underground targets. The sensors can be used for a variety of applications and for different e.m. sources. They can be configured as gradiometers, as vector or scaler sensors and can be used as internette ...

The objective of this project is to design a new large caliber naval gun to fit in a relatively small volume within a ship and yet be capable of firing ranges considerably greater than are presently available from equal caliber guns and ammunition. This gun will have a very short recoil whose greater recoil forces will be passed directly to major load bearing structure near the ship's ke ...

We propose to design a model of visual target acquisition that can predict human performance in detecting low-contrast targets in complex scenes. This model will build on current state-of-the-art computational models of early human vision and visual search, and use proven cognitive modeling methods (belief networks for situation assessment and expert systems for knowledge-based reasoning) to mode ...

The management and dissemination of Inboard and offboard information and the associated situation assessment of the tactical picture and determination of the associated response is a major task for Air Force personnel. Significant effort has been made in countering this challenge with advances in sensor capabilities. enhancements in onboard avionics, and combined intra and inter service command, c ...

This Phase I effort proposes to prototype and demonstrate a Case-Based Reasoning Tool for Command and Control Warfare (C2W) Strategy Development. Our effort is motivated by the need to thoroughly understand and graphically depict vulnerabilities in the information battle space since Intelligence Preparation of the Battle Space (IPIBS) is the fundamental basis for successful execution of C2-attack ...

The digitization of the tactical military environment with its concomitant increase in accessible information provides an opportunity to enhance decision-aiding capabilities of advanced Navy targeting systems. An approach employing intelligent software agents can facilitate enhanced decision-aiding by automating: the management and dissemination of relevant targeting information and intelligence ...
