Austral Engineering and Software, Inc. proposes to develop a computer platform for simulation-and-optimization-based design of multiple-stage manufacturing processes. Phase I will use metal forming processes to demonstrate feasibility of embedding analytical models of basic transport phenomena into design models that include geometric, microstructure, and processing features. Each stage of a me ...

Controlling millimeter radio frequency waves with optical signals is a requirement for military communications and radar systems. The advances in the past decade have led to photonic sensors and switches that utilize light beams interacting with RF devices. New capabilities extending to higher frequencies and working over multiple frequency bands are possible using a combination of nonlinear op ...

In spite of the fact that powerful desktop computers are readily available, the mechanics of antenna design has changed very little as a result. Computers are being used, but only as high speed calculators to solve models that were developed 30 years ago. Two new developments in electromagnetics have been recently published. The first is a general antenna pattern synthesis algorithm developed by ...

Simulation-based optimization techniques that enlist reinforcement learning controllers are ideally suited for complex and multi-objective optimization problems that cannot be solved easily using traditional techniques, especially when the stochastic natures or the environment, resources, and external interactive entities are taken into account. Reinforcement learning based on incremental value i ...

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 ...

The proposed experimental program demonstrates the technical feasibility of creating near-net shape single crystal components of technologically important ceramics. We propose to fabricate a near-net shape single crystal multilayer electrostrictive displacement actuator using a combination of the solid state method and advanced ceramics processing. The near net shape single crystal multilayer el ...

Human motion capture devices are in demand in a number of fields. Currently available systems are greatly limited in flexibility and quality. Furthermore, since they depend upon adorning the subject with suits of sensors or targets, the present art is totally unsuited to surveillance or reconnaissance. Without sensors or targets to place on the subject , detection, tracking, and measurement may ...

CTI and its subcontractors, BDM's Defense Enterprise Integration Team and Sonalysts, Inc., propose to apply a hybrid task analysis methodology to model critical functions in the CIC and derive measures of performance by individuals and teams. The approach is a hybrid in that it joins cognitive analysis techniques with methods typically used to in business re-engineering studies. In addition, it in ...

Recent cognitive research indicates that military teams operate effectively in high-stress, information-rich environments when they 1) share mental models of the battlefield situation and the team; 2) critique their situation model to develop clear goals for information retrieval; 3) effectively communicate information needs to others; and 4) anticipate and counteract information overload. We pro ...
