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 ...

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. ...

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 ...

BOVINE PANCREATIC RIBONUCLEASE A (RNASE A) IS A MODEL SYSTEMFOR ESTABLISHING RULES THAT GOVERN PROTEIN STABILITY AND FOLDING. BY LEARNING AND APPLYING THESE RULES, MORE ROBUST ENZYMES OF VARIOUS TYPES COULD BE DESIGNED FOR COMMERCIAL APPLICATIONS. SYNTHESIS, CLONING AND EXPRESSION IN BACILLUSSUBTILIS OF A GENE ENCODING RNASE A WILL ALLOW FOR THE ECONOMICAL PRODUCTION OF VARIANT PROTEINS WHICH ARE ...

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 ...
