MODELING OF THE AMBIENT AND PROMPT IONOSPHERIC REGIONS IN A THIN LAYER APPROXIMATION ALLOWS AN EFFICIENT METHOD OF DETERMINING THE TIME EVOLUTION, PROPAGATION, AND SIGNAL STRENGTH OF THE 0-10 SECOND MHD EMP ASSOCIATED WITH HIGH ALTITUDE NUCLEAR DETONATIONS.

SUBSTANTIAL PROGRESS HAS BEEN MADE IN RECENT YEARS TO DEVELOP AND VALIDATE MODELS WHICH CAN PREDICT THE PHYSICAL EFFECTS OF NUCLEAR WEAPONS ON STRATEGIC STRUCTURES. SIGNIFICANT UNCERTAINTIES REMAIN, HOWEVER, IN THE CONFIDENCE LEVELS ATTRIBUTABLE TO THESE PREDICTIVE CAPABILITIES. THIS APPROACH WOULD IDENTIFY AND PRIORITIZE THOSE ACTIVITIES, ALONG WITH THEIR ASSOCIATED BUDGETARY AND SCHEDULING CONSI ...

THE SPATIALLY RESOLVED PLASMA DISTRIBUTION BETWEEN THE ELECTRODES OF A PLASMA EROSION OPENING SWITCH (PEOS) DURING THE CLOSED AND OPENING PHASES OF THE SWITCH IS NEEDED TO UNDERSTAND SWITCH OPERATION. CONVENTIONAL HOLOGRAPHIC TECHNIQUES ARE NOT SUFFICIENTLY SENSITIVE TO STUDY THE 10 TO THE 13TH POWER/3CM PLASMA ENCOUNTERED HERE, AND ARRAYS OF LANGMUIR PROBES ARE REQUIRED TO OBTAIN SPATIALLY RESOLV ...

THE DISTRIBUTION OF THE MAGNETIC FIELD IN A HIGH CURRENT PLASMA DEVICE PROVIDES IMPORTANT INFORMATION ABOUT THE DEVICES OPERATION. TRADITIONAL FARADAY ROTATION, ZEEMAN EMISSION SPECTROSCOPY, AND MAGNETIC PROBE TECHNIQUES SUFFER FROM POOR SPATIAL RESOLUTION BECAUSE THE MAGNETIC FIELD EFFECT IS INTEGRATED ALONG THE LINE OF SIGHT FOR THE OPTICAL TECHNIQUE AND THE PROBES PERTURB THE PLASMAS. A LASER I ...

A CONCEPT FEASIBILITY STUDY FOR A SATELLITE-BASED OPTICAL-INFRARED DISTURBED ATMOSPHERE SIGNATURE PROGRAM IS PROPOSED. THE INITIAL CONCEPT IS FOR A POLAR-ORBITING OPTICAL-INFRARED ANALOG TO THE HILAT SATELLITE WHERE-IN A HIGH PROBABILITY OF AURORAL ACQUISITION IS ANTICIPATED. INITIAL TECHNICAL DIFFICULTIES OF CRYOGENIC OPERATION AND EXPECTED LIFETIME ARE DISCUSSED IN TERMS OF THE IRAS SUCCESS. THE ...

A PHYSICAL PROPERTY OF EARTH FORMATIONS THAT STRONGLY INFLUENCES THE RATE OF ATTENUATION OF A SHOCK WAVE IS THE BULK VOLUME OF AIR OR GAS ENTRAINED IN THE POROSITY. AS A RESULT, THE ACCURATE DETERMINATION OF THIS GAS VOLUME IS IMPORTANT FOR PREDICTING THE EFFECT OF A SHOCK WAVE ON SUBSURFACE STRUCTURES. THE OIL AND GAS INDUSTRY HAS USED GEOPHYSICAL WELL LOGS FOR YEARS TO IDENTIFY AND EVALUATE THE ...

THE OBJECTIVES OF THE PROPOSED EFFORT ARE TO DEVELOP A GEOTECHNICAL INVESTIGATION SCHEME AND A DESIGN METHODOLOGY FOR HARDENED UNDERGROUND STRUCTURES. THESE ARE TO BE ACHIEVED BY ENTENDING EXISTING NEW AUSTRIAN TUNNELING METHOD(NATM) TECHNIQUES THROUGH THEORETICAL MODELING COMBINED WITH EXPERIMENTATION TO ENABLE THEM TO BE USED FOR TWO PURPOSES: (1) TO DETERMINE, FROM NATM TECHNQUES THE GROSS PROP ...

The CONOPS for the Expeditionary Medical Support System (EMEDS) is based on practical effectiveness, speed, and efficiency. Key among the tools required by the Air Mobility Command and the Air Combat Command, which are two of the major commands that are part of the United Air Force is a multi-channel intravenous infusion pump capable of delivering fluids that meets the safe-to-fly criteria for all ...

Thegoal is to develop asoftwaretool that implementsa novelapproach applicableto fitgeneral pharmacologic, toxicology, or other biomedical data, that mayexhibita non-monotonic dose-responserelationship for which thecurrent parametricmodels fail. Thesoftwareexplores dose-responserelationships using both monotonicand non-monotonicmodels,and estimates theassociated doseresponsecurves,which can further ...
