Wild type (wt) dengue 1 viral RNA will be used as substrate to generate a complementary DNA (cDNA) library of clones that contain identified and sequenced DNA segments spanning the entire dengue 1 genome. Point mutations designed to generate amino acid alterations will be introduced at the nucleotide level in the cloned dengue 1 DNA sequences by polymerase chain reaction amplification. These mutat ...

A high response internal fault detection (IFD) and classification system is designed for large permanent magnet synchronous machines using multiple electromagnetic detection methods and thyristor controlled stator winding isolation techniques. Four broad categories of stator faults including dielectric failures, short circuit faults, core failures and open circuits are covered by the IFD. T ...

The proposed effort incolves the development of surgical simulation technologies that will both enable the Navy to provide improved training for trauma management and be broadly applicable to the improvement of civilian medical education. This project leverages High Techsplanations, Inc (HT) ongoing DOD (ARPA) and civilian work in virtual reality medical training system development. Phase I of t ...

An understanding of the shipbuilding construction and production issues, and the ability to implement this in ship designs, is key to the successful development of affordable Naval and commercial ships. Modern shipbuilding techniques involve assembling "blocks" that are pre-outfitted prior to actual ship installation. This results in complex design and 3D fabrication scheduling issues requiring ef ...

An operational requirement is projected for an inexpensive, mobile, submarine acoustic countermeasure capability. A significant tactical advantage is gained by putting as much distance as possible between the submarine (launch platform) and the mobile countermeasure. An additional advantage is gained if the submarine has the ability to place the ADC between itself and the torpedo threat. Adding ...

A first-principle mathematical model, designed to analyze parametrically the whole- ship impact of advances in ship technology, is to be developed to a level necessary to demonstrate feasibility as a result of the proposed Phase-I program of work. The model designated PASS for "Parametric Analysis of Naval Ship Systems" will be unique in as much as it will use algorithms derived from first-princip ...

An automated electrical load management system to provide load shedding during periods of high demand is required for adaptation to the V-22 Tilt-Rotor aircraft. A low cost and flexible system is required in order to extend current mission capabilities without significant overhaul of the electrical power system. Three steps toward solving this problem are: 1) determination of electrical load shedd ...

Changes in the world political situation from a U.S.-Soviet bipolarity to a new multipolar world have resulted in a change to the U.S. national military strategy. In this post-Soviet world, U.S. forces will be presented with not only expanded regional conflicts among Third World countries but also an increased nuclear, chemical, and biological (NBC) weapons threat in terms of diversity and frequen ...

Imaging bundles of infrared fibers will be developoed for use in an IR scene generation system. The fibers will be made from zirconium fluoride glass for the 3-5 micron region, and chalcogenide glass for the 8-12 micron region. Low loss chalcogenide glass fibers will be developed by improving the perform and fiber processing techniques, and using high purity starting materials and glasses. In part ...

The rapidly changing military signal environment has reduced the probability of detecting and correctly identifying signal emitters with conventional signal analysis techniques. Increasingly complex waveforms covering large spectral band-widths are now being used. In addition, the number of active emitters has increased dramatically. Coupled with this rapidly rising processing load is the use of t ...
