N/A

IT IS PROPOSED TO DEVELOP A MANAGEMENT METHODOLOGY FOR PERFORMING TRADEOFF STUDIES OF NUCLEAR SURVIVABILITY OPTIONS FOR BATTLEFIELD SYSTEMS. THE PURPOSE FOR THE METHODOLOGY IS TO PROVIDE SYSTEMS MANAGERS (AND THEIR ADVISERS) A METHOD FOR ENSURING THE COST-EFFECTIVE SURVIVABILITY TECHNIQUES ARE INCLUDED IN THE SYSTEMS PLANNING IN EARLY STAGES. THE INTENT OF THE PROPOSAL IS TO SUPPORT IMPLEMENTATION ...

THE CONTRACTOR HAS PATENTED TECHNOLOGY FOR A UNIQUE PROCESS THAT DIRECTLY CONVERTS AN ACOUSTIC SIGNAL INTO A VISIBLE ONE IN REAL-TIME WITHOUT ELECTRONIC CIRCUITRY. THIS RELIES ON THE ACOUSTO-OPTICAL PROPERTIES OF A CONTINUOUS LAYER OF LIQUID CRYSTAL THIN FILM LAYER WHICH SERVES AS BOTH THE SENSOR AND THE DISPLAY. THE IMAGE CAN BE VIEWED DIRECTLY BY MEANS OF CCD CAMERA. HOLOGRAPHY PROVIDES FOR BOTH ...

A GOOD MODEL FOR PREDICTING THE CONDUCTION AND OPENING CHARACTERISTICS OF PLASMA OPENING SWITCHES IS REQUIRED IF SWITCH- ES CURRENTLY IN USE ARE TO BE SCALED UP TO THE CURRENT AND VOLTAGE RATINGS REQUIRED BY THE FAMILY OF THREAT SIMULATOR. EMPIRICAL VERIFICATION OF THE NUMEROUS MODELS WHICH HAVE EVOLVED AROUND DIFFERENT CONDUCTION PROCESSES HAVE MET WITH LIMITED SUCCESS BECAUSE SWITCH CHARACTERIST ...

N/A

Survival of present day microelectronic circuits depends on their protection from self generated and external electromagnetic interference. This proposal is oriented toward the class of interference generally referred to as overvoltage transients. Means for mitigating these transients include gas discharge tubes, and various solid state devices. Each of these has their own advantages in particu ...

N/A

THE DAMAGING EFFECTS OF NUCLEAR AIRBLAST, THERMAL AND PROMPT RADITION, AND EMP ON EXPOSED EQUIPMENT AND STRUCTURES ARE WELL KNOWN. AN ADDITIONAL, LESS WIDELY RECOGNIZED BUT POTENTIALLY SERIOUS NUCLEAR EFFECT IS THAT OF AIRBLAST-INDUCED SHOCK (ABIS). EQUIPMENT MOUNTED INSIDE AN ENCLOSED SPACE CAN BE EXPOSED TO LARGE INDUCED VELOCITIES AND ACCELERATIONS, PRIMARLY IN THE HORIZONTAL DIRECTION. THE INT ...

We propose to design a compact, multiple purpose electromagnetic sensor for monitoring the extremely low frequency (ELF), very low frequency (VLF), and low frequency (LF) spectrum. Our goal is to design a modular, low cost sensor capable of being configured for multiple applications and capable of being employed in remote, unattended sensor networks. We describe three applications or scenarios t ...

Using distributed interactive simulation (DIS) to conduct effective training, analyses, or mission support in a tactical nuclear weapons effects (NWE) environment requires realistic computer generated forces (CGF) that are sensitive to such effects. This level of sensitivity requires CGF to apply valid and reliable speed-accuracy measures of environmental effects on human performance within the D ...
