The adaptive single user receiver invented at AF LAB has been shown to suppress multiuser and certain forms of narrow-band interference in adecision directed mode during the entire transmission, without requiring knowledge of other users spreading codes, timing or phase information in direct-sequence proposal, we investigate the use of our single user receiver for secure communications as required ...

While the efficiency of x-ray sources is defined by the laws of physics, present day sources do not take full advantage of those laws. Other materials thant tungsten are not only more efficient in producing bremsstrahlung, but have "characteristic" x-rays that can make the beam harder instead of softer (as in the case for tungsten). Today's tubes also do not use optimum angles for the incident e ...

The final prototype of the Microcircuit Board Repair apparatus will be capable of laying down or lifting metal strips with micrometer dimensions. Under real time computer control, the translation stages will be fully automated or manually controlled. The end user will monitor the process in real time using a camera attached with the source. Laying down the metal lines will be done using Laser C ...

The Navy's reinforced concrete structures represent an invaluable asset to the nation's defense preparedness. However, some facilities are approaching a critical state of disrepair and represent a substantial facility management burden due to uncontrolled severe deterioration of reinforced concrete in marine environments. Naval Facilities Engineering Service Center's professionals estimate that ...

To advance scientific and medical understanding of blood chemistry, we propose to develop modern medical simulation software that will be of use in predicting outcomes of medical interventions. For example, the chemical reactions between hemoglobin, oxygen, carbon dioxide, and electrolytes that occur in blood are essential to understanding human physiology, but still confuse students at many leve ...

The xpatch code suite, today combines a highly regarded high-frequency RCS prediction code with several visualization tools and a host of CAD editing and conversion programs. Currently, ideal conditions are always assumed by xpatch. In reality, sensor characteristics and atmospheric effects play a part in the appearance of a collected signature. In this proposal, we outline a course fo ...
