Army defense technologies for high speed threat intercept increasingly rely on vehicle maneuverability through both aerodynamic and thrust augmentation. Similarly, threats have relied on equally maneuvering defenses to avoid intercept. Thus, it is in the interest of any defense system to target the threat at any point in the battlespace where it is most vulnerable, potentially resulting in interce ...

The Global Positioning System (GPS) has revolutionized military operations by providing global access to high-quality position, navigation, and time (PNT) data. Along with the rise in GPS usage has been a parallel increase in threats to GPS data availability. GPS signals are easily jammed due to their low signal power and fixed frequency of operation. Spoofing attacks threaten military systems bei ...

A CENTRAL ELEMENT IN MILITARY EXPERT-SYSTEM (ES) APPLICATION IS THE DYNAMIC HANDLING AND ADAPTIVE CONTROL OF EVIDENCE AND UNCERTAINTY. THERE ARE CURRENTLY FIVE DISTINCT APPROACHES TO THE PROBLEM OF EVIDENTIAL REASONING (ER). THESE ARE THE BAYESIAN, NEYMAN-PEARSON, DEMPSTER-SHAFTER, KYBURG, AND POSSIBILITY/FUZZY APPROACHES. IN ADDITION TO THE ER TASK OF REVISING DEGREES OF BELIEF OR SUPPORT, WE MUS ...

WE HAVE DESIGNED A NOVEL WOUND DRESSING MATERIAL WHICH IS NONADHESIVE,BACTERICIDAL, BIOLOGICALLY COMPATIBLE (NONIMMUNOGENIC, NONINFLAMMATORY, NONTHROMBOGENIC) AND IMPERMEABLE TO BACTERIA. WOUND DRESSING MATERIALS IN USE TODAY (EXAMPLE: GAUZE) CAN BE TREATED WITH AN INSOLUBLE, ANTIBIOTIC-CONTAINING, HYALURONIC ACID (HA) COATING TO PROVIDE A PERMEABLE, NONADHESIVE (CLOTTED BLOOD-WET OR DRYWILL NOT B ...

Today’s warfighter is often called upon to operate in extremely cold environments, both in operational and training settings. These environments can range from operating or training in geographical or seasonally cold areas to performing a high altitude, high opening (HAHO) or high altitude, low opening (HALO) parachute jump in extremely cold ambient temperatures. To operate in these environments ...

CERAMICS HAVE BEEN DEMONSTRATED TO BE VIABLE ALTERNATIVES IN CONVENTIONAL AND ADIABATIC DIESEL ENGINES WITH THE POTENTIAL OF 30% FUEL SAVINGS. THERE IS AN INTERNATIONAL COMPETITION TO DEVELOP CERAMICS IN GENERAL AND SPECIFICALLY FOR DIESEL ENGINES. IN AMBITIOUS DOMESTIC AND FOREIGN PROGRAMS TO UTILIZE CERAMICS IN DIESELS, THE LIMITATION OF CURRENTLY AVAILABLE CERAMICS HAVE BEEN IDENTIFIED. IN META ...

Emerging missile threats to Army assets often fly through and maneuver at higher altitudes. In addition, Army interceptors launch from the ground and will likewise need to fly through / maneuver at higher altitudes to engage such threats. The associated changes in flight conditions cause threat and interceptor signatures to change substantially from those usually observed by Army sensors and seeke ...

THE PROPOSED RESEARCH IS TO ADVANCE THE STATE-OF-THE-ART OF DETERMINISTIC RISK ANALYSIS AND FIRE PROTECTION METHODOLOGY OF NUCLEAR POWER PLANTS. A COMPUTER CODE, BASED ON THE USE OF A FIELD (DISCRETIZATION) MODELING TECHNIQUE, WILL BE DEVELOPED THAT HAS SUFFICIENT FLEXIBILITY FOR ACCURATE/REALISTIC REPRESENTATIONS OF GEOMETRY, VENTILATION AND OTHER CONDITIONS PRESENT IN CABLE ROOMS AND CONTROL ROO ...

A CONTROLLED RELEASE ANTIBIOTIC WOUND DRESSING IS TO BE DEVELOPED FOR ADMINISTRATION OF BACITRACIN AND POLYMIX B. THE DRESSING IS TO BE EASILY APPLIED AND CONFORMABLE TO WOUND SURFACES. BOTH ANTIBIOTICS ARE TO BE MAINTAINED AT EFFECTIVE LEVELS WITHIN WOULDS FOR THREE DAYS, PREVENTING INFECTION FOR THIS PERIOD OF TIME. THE DRESSING IS TO BE INCORPORATED INTO POROPLASTIC CELLULOSE TRIACETATE MEMBRAN ...
