A simulation tool is proposed to model and simulate the wind fields, turbulence fields, and the unsteady dispersion of NCBR substances in urban areas on the building to city blocks scale. This Computational Fluid Dynamics (CFD)-based approach has beenshown to accurately simulate the urban wind and turbulence fields with minimal approximations, and has been demonstrated by modeling the flow fields ...

THE PROGRAM PROPOSED BY DESE RESEARCH AND ITS PROPOSED SUBCONTRACTOR, BROOKHAVEN NATIONAL LABS., IS DESIGNED TO DEMONSTRATE THE TECHNICAL FEASIBILITY OF REMOTE TECHNICAL MONITORING OF CHEMICAL AGENTS. TECHNICAL OBJEECTIVES DURING PHASE I OF THE PROGRAM ARE TO: DEMONSTRATE THE CONCEPTUAL FEASIBILITY OF REMOTE SENSING OF CHEMICAL AGENTS THROUGH APROGRAM THAT: DEFENSES TREATY DRIVEN SYSTEM REQUIREMEN ...

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 GREAT DEAL OF EFFORT HAS BEEN SPENT IN RECENT YEARS TO DEVELOP STANDARDIZED METHODOLOGIES FOR ACCEPTING AND VERIFYING EMP HARDENED MILITARY FACILITIES. THE FIRST OF THESE STANDARDIZATION EFFORTS TO BE PUT INTO EFFECT APPLIES TO FIXED SITE, CRITICAL, TIME URGENT C4I FACILITIES. THE REQUIREMENTS EXISTS FOR AN ADVANCED INSTRUMENTATION APPROACH THAT CAN OVERCOME THE DIFFICULT ACQUISITION ENVIRONMENT ...

ONE COMMON NUCLEAR WEAPONS EFFECTS CIMULATION TECHNIQUE SIMULATES THE EMP RESPONSE OF LONG CABLES USING DIRECT CURRENT INJECTION. DIRECT CURRENT INJECTION TYPICALLY INVOLVES THE CONNECTION OF HIGH VOLTAGE PULSE SOURCES TO THE CABLES THAT ARE ATTACHED TO A MILITARY SYSTEM. A RECENTLY DEVELOPED MILITARY STANDARD SPECIFIES THAT DIRECT CURRENT INJECTION TESTING WILL BE USED IN CONJUNCTION WITH SEVERAL ...

Large X-ray generators using gas fill loads are a key element in the DTRA simulator program. Consistent relative timing between the injection of the gas shell and the generator current pulse is crucial to producing consistent, high-yield x-ray pulses.To that end HY-Tech proposes replacing existing high voltage trigger pin technology, with a sensitive, all fiber-optic heterodyne interferometer ba ...

OBJECTIVE: Develop a Forensic DNA Analysis Kit for Genetic Intelligence that can be used on unknown human DNA samples collected from the battlefield to provide information about the individual who deposited the sample, such as potential ethnicity, height, eye color, hair color, age, sex, and/or facial features. The kit should leverage Short Tandem Repeats (STR), Single Nucleotide Polymorphisms (S ...
