A novel approach for controlling weld bead penetration is proposed. The methodology is distinguished from past techniques by use of: 1) a new and more accurate model of the weld pool dynamic behavior, 2) an improved method of sensing the weld pool oscillations, 3) a more efficient method of weld pool excitation, and 4) a model-based relation of pool dynamics, weld pool geometry, and equipment para ...

The Virtual Environment Training for Battlefield Medical Personnel (VETBMP) project is the development of a simulation architecture designed to integrate procedural simulations, intelligent tutoring, and various sensory input devices to create a realistic training scenario for 'forward' military personnel. Phase I of VETBMP will be a simulation of a standard medic task (intravenous infusion), emb ...

The primary objective of the proposed investigation is to develop numerical tools capable of producing scalable algorithms for efficient solution of a general class of large geophysical inverse problem in a massively parallel processing (MPP) computing environment. An example problem is the rigorous solution of the Earth's gravity field using massive satellite data. Currently, such a solution can ...

THE CONCEPTUAL DESIGN OF A LOW COST MOBILE ROBOT WILL BE PREPARED UTILIZING PROVEN AND EXISTING TECHNOLOGY AND COMPONENT. REQUIREMENTS WILL BE ESTABLISHED BY SURVEYING POTENTIAL EDUCATIONAL AND LABORATORY USERS. ALTERNATE MODES OF MOBILITY WILL BE EVALUATED. MODULARITY AND INTERFACES WILL BE DEFINED FOR A VARIETY OF ADD-ON SENSORS INCLUDING VISION, SOUND, SONAR, HEAT AND MANIPULATIONS. ON-BOARD LO ...

This SBIR will explore and develop new automated methods for dynamic fault tolerance in defense electronic systems. The research will investigate using the software of digital signal processor operating systems to pro-actively map defective operations to remaining processors. In the past, fault tolerance has relied on passive redundancy to extend operating life. With software, a simple re-start ...

CONVENTIONAL MOLECULAR BEAM EPITAXY (MBE) GROWTH CONTROL SYSTEMS ARE EITHER OPERATED MANUALLY OR WITH SIMPLE LINEAR CONTROLLERS USING PREDEFINED RECIPES. WE WILL SUPPLEMENT A STANDARD CONTROL SYSTEM WITH A NEURAL NETWORK BASED CONTROLLER. THE NEURAL NETWORK WILL BE TAUGHT BY GROWING GAAS/ALGAAS SUPERLATTICES USING THE CONVENTIONAL TECHNIQUES. SUBSEQUENTLY, THE NEURAL NETWORK WILL BE ALLOWED TO TAK ...

RELIABLE OBJECT-BASED CONTROL SOFTWARE (ROCS) ISA PROGRAMMING TECHNOLOGY THAT CAN BE COMBINED WITH BOTH INDUSTRIAL PROGRAMMABLE CONTROLLERS AND POWERFUL RISC BASED PROCESSORS TO CONSTRUCTFLEXIBLE CONTROL COMPONENTS OF GENERAL PURPOSE MACHINE TOOLS. ROCS ALSO SUPPORTS THE COMBINATION OF THOSE COMPONENTS INTO INNOVATIVE STATION, CELL, CENTER OR FACTORY AUTOMATION CONCEPTS. THE PROPOSED TECHNOLOGY WO ...

RAMAN SPECTROSCOPY IS AN EXCELLENT MEANS FOR NON-CONTACT PROBING OF QUALITY AND TEMPERATURE OF MANY MATERIALS (III-V SEMICONDUCTORS, DIAMONDS, ETC.) WHICH ARE GROWN IN CHEMICAL VAPOR DEPOSITION (CVD) REACTORS. IT CAN MEASURE COMPOSITION, TEMPERATURE, STRAIN, DEGREE OF CRYSTALLINITY, AND PRESENCE OF CONTAMINATION EX-SITU. AS AN OPTICAL PROBE IT CAN READILY PENETRATE THE HIGH PRESSURE GASES WHILE A ...
