Existing balloting codes do not consider all of the forces and interactions that contribute to balloting of hypervelocity projectiles. This effort will result in the definition of a complete mathematical model and the design of an appropriate, user friendly, computational model to predict hypervelocity projectile balloting. Arrow Tech, whose engineers are well known for the development and applica ...

The work involves the design and testing of new enzyme-based amperometric glucose sensors. Electrical communication between the flavin redox centers of glucose oxidase and an electrode is achieved via a network of donor-acceptor relays chemically bound to a highly flexible, insoluble, high molecular weight polymer. Improvements in stability and selectivity will be pursued through the use of protec ...

The overall objective is to develop highly stable electrochemical probes for the monitoring of the reduced cofactor nicotinamide adenine dinucleotide (NADH), which is produced in many enzyme-based immunoassays. These sensors can measure NADH concentrations at low applied potentials, where electrochemical interferences and deactivating chemical reactions are avoided. The Phase I research will attem ...

This project will design and evaluate software prototypes to examine three issues in hypermedia design. 1. What is the proper balance between user and system control? 2. What strategic knowledge is needed to take advantage of the new dimensions of information available and how can the system's design aid in the acquisition of the knowledge? 3. What is the most effective way to integrate informatio ...

The development of improved implantable devices and biomaterials requires knowledge of their in vivo behavior. However, little is known about the actual loads borne by implanted devices in vivo. Direct measurement of these loads would provide extremely valuable information for the improvement of device designs and rapid rehabilitation of individuals with implanted devices. Multi-channel telemetry ...

Inside Out vs Outside In! It seems reasonable to hypothesize that the pilot of an air vehicle will feel more in harmony with the actions of his vehicle when he is at the relative "origin" of the coordinate frame of reference of that vehicle ... and will respond more quickly and with greater accuracy, precision, and efficiency. Experience teaches that this occurs for a piot when utilizing an "insid ...

Improving our current ability to measure the shape of x-ray focusing mirrors is necessary to advance our knowledge of the atomic structure of many types of materials, especially for the latest diffraction-limited light sources within the DOE. X-ray studies at DOE national laboratories of the atomic structure of new materials, biological molecules, etc. are limited by the quality of the x-ray spot ...
