Currently, advanced tools for modeling injection modeling of thermoplastics and predicting formed part dimensional stability and residual stress content use the static bulk modulus of the polymer at the temperatures and pressures associated with the molding process. The short cycle times associated with injection molding, however, could be more accurately modeled if dynamic bulk modulus data were ...

NIST's seeks a high resolution DIC technology for qualification of complex AM parts. To meet this critical need, X-wave Innovations Inc. proposes to develop a 3-Dimentional Digital Image Correlation (3-D DIC) based NDT system. The proposed effort builds upon the success of XII in developing a variety of NDT technologies (including DIC system) for advanced materials evaluation. The success of the p ...

NOAA AVHRR DATA HAS PROVIDED USEFUL QUALITATIVE INFORMATION IN AGRICULTURE AND FORESTRY APPLICATIONS. QUANTITATIVE APPLICATIONS OF AVHRR ARE HOWEVER IN THEIR INFANCY. STUDIES BY EARTHSAT PERSONNEL HAVE SHOWN THAT FOR ONE YEAR IN ONE LOCATION CORN YIELD CAN BE QUANTITATIVELY RELATED TO AVHRR VEGETATION INDEX COUNT VALUES. THE PROPOSED STUDIES WILL EXAMINE FURTHER QUANTITATIVE APPLICATIONS OF AVHRR ...

The goal of this project is to develop an demonstrate the feasibility of computer-based, multimedia instruction to facilitate the acquisition of difficult to learn mathematics principles. The goal will be accomplished through the design and development of a multimedia interface that uses audio prompts, interaction graphics, and text displays to guide learners through problem solving activities. ...

The ISABEL program will create symbolic execution signatures to classify bugs in the NIST Bugs Framework. Using the symbolic execution signature ISABEL will find a program input to trigger the bug using fuzz testing. ISABEL will integrate its bug categorization and bug triggering capability with a software development environment using a flexible framework that will allow both open source and comm ...

Advanced manufacture requires low-latency and high-reliability wireless communications between the sensors/actuators and the central controller. However, the current wireless protocols cannot meet such stringent latency and reliability requirements. In this project, InfoBeyond advocates L2Wireless (Low-Latency High-reliability Wireless Protocol Using Cooperative Relaying and Network Coding) to add ...

SPECIAL MILITARY NARROW BEAM ACOUSTIC PROJECTORS AND TRANSMISSION TECHNIQUES CAN BE EASILY ADAPTED FOR COMMERCIAL USE TO ENABLE FISHERMEN OR RESEARCHERS TO DETECT,LOCATE, AND QUANTIFY BIOLOGICAL TARGETS WITH VERY HIGH ACCURACY IN SHALLOW WATER. THE PROPOSED EFFORT WILL PROVIDE A METHOD FOR PRODUCING VERY NARROW ACOUSTIC BEAMS WITH VIRTUALLY NO SIDELOBES FROM A SMALL APERTURE PROJECTOR ARRAY. ALSO ...
