Defense Electronics Corporation (DEC) proposes an innovative radiation hardened by design (RHBD) and reliability improvement solution for silicon, III-V compounds (e.g. SiGe, SiC, GaN, InP, GaAs,), carbon nanotubes (CNT), and graphene. The method is based on analyzing chip-partitioned quiescent current signatures associated with failure modes common to these process technologies. Furthermore, the ...

This proposal concerns the detection of Special Nuclear Materials (SNM) by using large networks of small, inexpensive, and robust gamma detectors. These detectors will be deployed where consistent surveillance would be difficult by any other means, like remote mountain trails. The proposal describes a novel gamma detector that is extremely robust and inexpensive. The new scintillation material is ...

The Ktech Team proposes a feasibility study of a fuel/air driven flux compression power unit (FCPU) for electric guns. Through variations of inductance gradients and through changes in scale, the proposed technology will be applicable to both electrothermal/chemical and electromagnetic guns. In the Phase 1 effort, we develop simulation models to predict the performance of the flux compression po ...

The Defense Nuclear Agency hase undertaken several related programs to develop new technologies for countering the proliferation of weapons of mass destruction, including weapons which disperse dry spore biological agents. These initiatives require an increased understanding of the response o fthese agents and their surrogates to the environments generated by various weapons, including penetratin ...

DEVELOPMENT OF AN INNOVATIVE AND ECONOMICAL EXPERIMENTAL METHOD IS PROPOSED WHICH CAN PROVIDE THE BASIC BEHAVIOR DATA NECESSARY TO MEET THE DNA OBJECTIVE OF PROVIDING ADEQUATE ANALYSIS, DESIGN AND ASSESSMENT METHODS FOR MINIMALLY HARDENED TUNNELS. THIS DEVELOPMENT IS ACCOMPANIED BY ANALYSIS CAPABLE OF REPRESENTING THE COMPLEX INELASTIC MATERIAL BEHAVIOR OF THE ROCK MASS AND OF REPRESENTING SIMPLE ...

THE INTENT OF DOD INSTRUCTION 4245.4, "ACQUISITION OF NUCLEAR SURVIVAL SYSTEMS" IS TO PROVIDE FOR NUCLEAR SURVIVABILITY THROUGHOUT THE LIFE CYCLE OF WEAPON SYSTEMS WHICH ARE REQUIRED TO SURVIVE THE EFFECTS OF NUCLEAR WEAPONS. ONE KEY TO IMPLEMENTING THIS INTENT IS TO INSURE THAT ALL THE PEOPLE INVOLVED ARE FAMILIAR WITH THEIR RESPONSIBILITIES TO IMPLEMENT AND PRESERVE THIS SURVIVABILITY. THIS STUD ...

IMPULSIVE SOURCES (LANDSLIDES, EXPLOSIONS, AND SO FORTH) ARE CAPABLE PRODUCING EXTREMELY LARGE WAVES IN SUFFICIENTLY DEEP WATER. IF CONTAINED IN A STEEP-WALLED FORD-LIKE CHANNEL, SUCH WAVES CAN BE PROPAGATED WITH LITTLE LOSS OF ENERGY OVER SIGNIFICANT DISTANCES. THE MAJOR ENERGY DISSIPATOR IN THIS CASE MIGHT BE THE OCCURRENCE OF BREAKING IN THE NARROW SHALLOW ZONES ALONG EACH BANK; THIS LOSS MECHA ...

THE OBJECTIVE OF THIS PROJECT IS TO DEVELOP AN IMPROVED DIFFERENTIAL PRESSURE GAGE FOR DETERMINING DYNAMIC PRESSURE WITHIN BLAST AND SHOCK WAVE FLOWS WHERE THE FLOWS ARE SUBSONIC. DERIVATION OF DYNAMIC PRESSURE FROM A MEASUREMENT OF THE DIFFERENCE BETWEEN STAGNATION PRESSURE AND SIDE-ON OR STATIC PRESSURE REQUIRES USE OF THE SIDE-ON PRESSURE RECORD TO CORRECT FOR COMPRESSIBILITY EFFECTS. CURRENTLY ...
