In Phase I, we will investigate a case-based reasoning (CBR) approach to intelligent tutoring systems (ITSs) and explore the feasibility of semi-automated/automated course authoring techniques to speed collection and structuring of domain knowledge. We will develop a prototype example-based ITS, enhanced with multimedia, within a specific Navy instructional domain and a generic ITS architec ...

In Phase I, we will investigate a case-based reasoning (CBR) approach to Operator Assessment and Operator Machine Interface Enhancement and explore the feasibility of semi-automated/automated domain knowledge entry techniques to speed collection and structuring of domain knowledge. We will develop a prototype case-based Operator Assessment and Operator Machine Interface Enhancement System (O ...

The ultimate aim of this research is to develop a computer system to aid in producing accurate parts obsolescence predictions. This can be accomplished through the automated use of previous experience, which consists of information on existing parts. The feasibility of an automated system which uses existing components as cases to aid the obsolescence prediction for a current part will be demonstr ...

We propose to design and fabricate a high performance anamorphic adapter for commercial off-the-shelf (COTS) infrared array cameras. With this anamorphic system, the viewing angle along the preferred axis can be maximized and the viewing angle along the orthogonal axis can be diminished while an equal projected area per pixel can be maintained. The viewing angles for the proposed system with an is ...

THIS PROPOSAL DESCRIBES A PROGRAM TO DEVELOP A COMPACT, RUGGED, AND AUTONOMOUS PROGRAMMABLE LASER DOPPLER VELOCIMETER (LDV) FOR MARINE APPLICATIONS. THE SYSTEM WILL INCLUDE TWO MAJOR INNOVATIONS IN LDV TECHNOLOGY: A PROGRAMMABLE DIGITAL SIGNAL PROCESSOR (DSP), AND A PULSED LASER DIODE. THE DSP PROVIDES THE HIGHEST COMPUTATIONAL POWER AND PROGRAMMABILITY IN A COMPACT SIZE ALLOWING THE IMPLEMENTATIO ...

THIS PROPOSAL PRESENTS AN INNOVATIVE APPROACH TO DETERMINING THE PROPAGATION PATH OF ACOUSTIC DATA RECEIVED BY A THIN LINE TOWED ARRAY. WE MAKE USE OF THE LATEST DEVELOPMENTS IN SEAFLOOR ACOUSTIC MODELING CAPABILITY AS WELL AS EMPLOYING THE EMERGING AND POWERFUL TECHNIQUES ASSOCIATED WITH ARTIFICAL NEURAL NETWORKS. THE PROPOSED NEURAL NETWORKS WILL BE DESIGNED TO IDENTIFY THE PATH OF PROPAGATION F ...

The purpose of Phase I of this project is to determine the feasibility of developing an acoustic instrument for measuring temperature and other scalar profiles remotely through the absorption signature on the backscattered echo strength. The primary Phase I objectives are to develop short-term and long-term error models for both phase-slope and two-frequency implementation methods, determine optim ...

DDL OMNI Engineering proposes to design a secure system for the continuous, real time acoustic measurement of towed array position relative to the host submarine. By using focused transmit and receive assemblies, pseudo- random spread broadband signals, and relatively high carrier frequency, the transmission level will be minimized so as to be virtually undetectable by a non-dedicated system ...
