THE OBJECTIVE OF THIS PHASE I RESEARCH IS TO DETERMINE THE FEASIBILITY OF UTILIZING ACOUSTIC RADIATION FROM VEHICLE TIRES TO PROVIDE A LOW COST, EASY TO DEPLOY, UNOBTRUSIVE, RELAIBLE REPLACEMENT FOR THE CURRENT METHOD OF COLLECTING VEHICLE AXLE PASSAGE DATA. THE PROPOSED METHOD WILL CROSS-CORRELATE THE TIRE NOISE RECEIVED AT SPATIALLY SEPARATED MICROPHONES TO LOCATE AXLE CROSSINGS. THE PROCESSING ...

Existing physics-based device simulation tools are prohibitively expensive computationally, and therefore ill-suited for parametric analysis and design optimization of photonic integrated circuits (PIC). The proposed effort aims to develop and demonstrate an innovative, easy-to-use simulation tool for accurate, fast circuit/system analysis of PICs. The salient aspects of the proposed solution are: ...

This effort proposes to develop a toolset to evaluate the effectiveness of a safety-controller that monitors a learning-based autonomous control system. The traditional use of deterministic verification techniques for real-time monitoring is not feasible in the presence of uncertainty. This effort would advance the recommended verification techniques to include non-deterministic approaches. The ...

A new liquid crystal based detector (acousto-optic sensor) will be developed for operation at frequencies below 500kHkz. The superior acoustic detection sensitivity of the sensor will be demonstrated and its feasibility for providing efficient and cost-effective means of acousto-optic image conversion in underwater acoustic imaging systems will be established.

Barron Associates has assembled a team of researchers that include Dr. Sayan Mitra of the University of Illinois and Dr. Ufuk Topcu of the University of Pennsylvania. They will spearhead three complimentary investigations into the development of verification and validation (V & V) approaches for adaptive systems protected by run time assurance (RTA) mechanisms. Two of these approaches involve us ...

Federal, state, local, and military missions for Disaster Relief, Emergency Action, and Humanitarian Assistance (DREAHA) require all of the traditional command, control, communications, computer and intelligence (C4I) functions used by military units for traditional warfare. New civilian systems that leverage and reuse military C4I systems to plan, prepare, identify, vector, monitor, and recover ...

The Defense Modeling & Simulation Office (DMSO) is in the process of defining a common technical framework for modeling and simulation to promote interoperability and reuse, and has established the High-Level Architecture (HLA) to which all DoD simulation must conform. This decree has led to the need for a modular data management system capable of passively collecting data from an HLA federation ...
