In this proposal, we will develop a uniform framework, called a multimedia mediator, for integrating and querying multimedia data as well as heterogenous data located on a distributed network. The multimedia mediator will use distributed computing technology to scale up to real-world applications. We will develop graphical query languages and query engines whereby an end-user can query a system ...

AbTech Corporation proposes to apply its unique abductive information modeling (AIMTM) technology to develop a sensor fusion demonstration for command, control, communication, computer and information systems. Phase I is the necessary and sufficient precursor to an operational disparate sensor fusion for C4I applications. Phase I will show the feasibility of using AIM to model sensor data, threats ...

THIS PROJECT, IF SUCCESSFUL, SHOULD PROVIDE: A GENERAL MODEL AND PROCEDURE FOR USE IN DESIGNING PIEZOELECTRIC SENSORS -HYDROPHONES, ACCELEROMETERS, ETC.--WHICH WOULD ENABLE THE DESIGNER OF A SENSOR TO PREDICT ITS SENSITIVITIES TO THE STIMULUS FOR WHICH IT WAS DESIGNED, AND TO EXTRANEOUS STIMULI WHICH GENERATE INTERFERING SIGNALS; INFORMATION ON HOW THE CHOICE OF PIEZOELECTRIC MATERIAL AND MODE OF ...

Cured aircraft composite materials present a particularly difficult challenge for recycling technology. Those materials have mostly thermosetting epoxy matrices and occur in intimate association with metals, paints, and coatings. Current techniques for recycling thermoset composites, mostly for automotive sheet molding compounds (SMC), involve pulverizing the material for use as fillers. Th ...

A novel tertiary recycling process is proposed for investigation as an economical means for recycling shipboard plastic waste. Early development work has shown that this process can convert a wide variety of polymers and composites into low molecular weight hydrocarbons at temperatures below 200'C. The hydrocarbons produced can then be reused as chemicals, fuels, or monomers. Metal, glass, and fil ...

Currently, airbreathing propulsion systems which operate in the subsonic to high supersonic regime are expensive, complex and heavy. To overcome these limitations, a novel propulsion concept based on a liquid hydrocarbon-fueled Pulse Detonation Engine (PDE) is proposed. The innovation draws from recent successes in computational fluid dynamics and from several engineering studies and PDE develop ...

THE OBJECTIVE OF THE PROPOSED PROJECT IS TO ASSEMBLE AVAILABLE SOFTWARE PROGRAMS INTO AN INTELLIGENCT RDT&E MANAGEMENT INFORMATION SYSTEM (MIS) FOR PERSONAL COMPUTERS.

THE INTEGRATION OF VOICE AND DATA PRESENTS AN OPPORTUNITY TO USE HERETOFORE IDLE SECURE VOICE LINK CAPACITY, AND THE CHALLENGE OF IMPLEMENTING PROTOCOLS SUPPORTING BOTH VOICE AND DATA. THE NEW ARCHITECTURE DEMANDS A LAYERED FUNCTIONAL IMPLEMENTATION SIMILAR TO THE INTERNATIONAL STANDARDS ORGANIZATION (ISO) OPEN SYSTEMS INTERCONNECT (OSI) MODEL AND THE ABILITY TO GLOBALLY ADDRESS ANY MESSAGE, DATA ...

A MODEL FOR PREDICTING THE PERFORMANCE IMPACT OF ENGINE DETERIORATION IS PROPOSED FOR FEASIBILITY EVALUATION. THIS MODEL WOULD ACCOUNT FOR ROTATING COMPONENT DETERIORATION SUCH AS INCREASED TIP CLEARANCES, SURFACE ROUGHNESS, LEADING EDGE BLUNTNESS AND VAN BOW AND TWIST. THE PROPOSED APPROACH USES A STAGE STACKING METHOD TO ALLOCATE LOSSES THROUGHOUT THE ENGINE WHICH ARE DEPENDENT ON OPERATING TIME ...
