With the current state of world events, the threat of explosives used against high-value targets is more pronounced than ever before. As a result, simulation of blast events and their effects on structures has become an increasingly vital capability. Current blast simulations on Central Processing Units (CPU) resources require a significant amount of computational time, limiting their overall valu ...

Electronic equipment, especially communication equipment, is extremely vulnerable to various forms of electromagnetic radiation whether natural or man-made due to minimal shielding and high sensitivity to radio waves. An ideal transient hardening device would limit the harmful energy as it enters the circuitry by minimizing the over-voltage. It would have to respond very fast and be able to handl ...

The objective of the proposed program is to develop a portable, low-cost, label-free (reagentless), microarray system capable of near real-time simultaneous detection and identification of multiple analytes (bacteria, viruses, spores, toxins) with highsensitivity and low false alarm rate. Notably, the system will be capable of detection/identification of agents on the basis of protein and/or nucl ...

THIS DOCUMENT PROPOSES RESEARCH ON THE FABRICATION OF A FAMILY OF EMP HARDENED CONNECTORS AND CABLE HARDWARE FOR AIRCRAFT AND SHIPBOARD APPLICATIONS. THESE CONNECTORS AND CABLE HARDWARE WOULD SUPPRESS EMP TRANSIENTS THROUGH THE INTEGRAL INCORPORATION OF A THIN FILM, HIGH SPEED, HIGH CURRENT OVONIC THRESHOLD SWITCH (OTS). CABLES AND HARDWARE OF THIS TYPE WOULD SIGNIFICANTLY INCREASE THE SURVIVABILI ...

ACCURATE CHEMICAL ANALYSIS AT POTENTIAL SITES OF CHEMICAL WARFARE (CW) AGENT MANUFACTURE, STORAGE OR USE IS OF GREAT VALUE FOR DETERMINATION OF CW TREATY VIOLATIONS AND FOR VERIFICATION OF DESTRUCTION OR REMOVAL OF CW AGENT SYSTEMS. RECENT DEVELOPMENTS IN HAND- HELD GAS CHROMATOGRAPHY/ION MOBILITY SPECTROMETRY (GC/IMS) FOR DIRECT AIR MONITORING HAVE ILLUSTRATED THE POTENTIAL OF THIS TECHNIQUE FOR ...

PROTECTION OF EXOATMOSPHERIC SYSTEMS AND STRUCTURES FROM NUCLEAR EFFECTS IS REQUIRED. THE MATERIAL CANDIDATE FOR THIS TYPE OF PROTECTION IS A CARBON-CARBON COMPOSITE FOR STRUCTURAL INTEGRITY AND TUNGSTEN CARBIDE COMPONENT FOR NUCLEAR HARDENING. THE CARBON-CARBON COMBINES A HIGH STRENGTH-TO-WEIGHT RATIO IN AN INTEGRAL STRUCTURAL COMPOSITE CAPABLE OF NUCLEAR HARDENING BY THE ADDITION OF TUNGSTEN CAR ...

UTILIZING TECHNIQUES DEVELOPED EXTENSIVELY IN THE NATIONAL LASER FUSION PROGRAM, WE PROPOSE TO MEASURE THE TIME DEPENDENT CHANGE IN CRYSTAL X-RAY REFLECTIVITY BROUGHT ABOUT WHEN A CRYSTAL IS HEATED TO THE MELTING POINT ON A PICOSECOND TIME SCALE. THIS EXPERIMENT WILL OBTAIN DATA ON RADIATION-LATTICE DYNAMICS ON A TIME SCALE 2-3 ORDERS OF MAGNITUDE FASTER THAN PREVIOUSLY OBTAINED WITH X-RAY TECHNIQ ...

One of the critical gaps in homeland security is the inability to efficiently detect and identify kilogram-size samples of Special Nuclear Materials (SNM, uranium and transuranic elements). Unlike other forms of radiation produced by SNM (e.g. gamma rays), penetrating neutron emission is unique to fissionable material and difficult to obscure with passive shielding. The current state-of-the-art ...
