Multi-Scale Model of Failure in a Composite Material

An adaptive concurrent multilevel computational model of failure in a heterogeneous-material structure has been developed. As used here, "concurrent" is a term of art characterizing a class of structural/material models that (1) incorporate submodels representing material substructures at...

Two-Processor Autopilot System for a UAV

Atwo-processor autopilot control system for an unmanned aerial vehicle (UAV) has been proposed and partly developed. Relative to prior such systems, this would be a lightweight, inexpensive autopilot...

A research effort now underway addresses fundamental mathematical issues involved in a methodology of creating flexible machine vision systems that would be able to modify their...

Intelligence Fusion System Tracks Mobile Targets

Current intelligence fusion systems are not accurately and quickly performing the intelligence, surveillance, and reconnaissance (ISR) fusion necessary for tracking moving targets that use...

Recent advances in the development of microsensors, microprocessors, information fusion algorithms, and ad hoc networking have led to increasingly capable wireless...

Military Worth Analysis of New Concept Weapons

Weapon systems analysts traditionally conduct military worth analysis (MWA) to evaluate the warfighter payoff resulting either from the development and implementation of new assets or from the...

Developing Condition-Based Maintenance

Like any manufacturing equipment, semiconductor fabrication systems have a finite lifetime. Technicians normally perform maintenance on these hardware systems according to preset schedules and...

When weaponeering a target, military planners pinpoint a detonation location that will result in the desired damage to the entire target, or even a particular area within the target. The...

Coordination of Autonomous Unmanned Air Vehicles

Future autonomous unmanned air vehicles (UAV) will need to work in teams to share information and coordinate activities in much the same way as current manned air systems. Funded by AFRL,...
