In an effort to development more robust optical system coatings DTRA, in collaboration with Sandia National Labs, is working to characterize the degradation of optical materials for space systems when exposed to high intensely EUV/ cold x-rays. The experiments utilizes the Double Eagle z-pinch facility which generates high current, high voltage arc pinch plasma to produce an intense EUV and cold x ...

This project team will fully develop and test AlphaBear 2, a vocabulary learning game for grade 4 to 7 students. Vocabulary is a prerequisite for academic success, as it is linked to stronger performance across academic subjects and improved reading comprehension. It is more difficult for students to participate in educational activities without understanding the key vocabulary associated with tha ...

TIME-TEMPERATURE MODELING OF ORGANIC MATTER MATURATION HAS BECOME AN IMPORTANT TOOL IN PETROLEUM AND GAS EXPLORATION INRECENT YEARS. THE MOST SERIOUS DIFFICULTIES IN APPLYING THESE MODELS ARE: 1) OBTAINING ACCURATE DOWNHOLE GEOLOGICAL INFORMATION, AND 2) ESTIMATION OF KINETIC PARAMETERS. SINGLE COLLECTIVE KINETIC RATES ARE TYPICALLY MEASURED IN THE LABORATORY. THESE MUST THEN BE APPLIED ON MUCH LO ...

OUR OUTLINED PLANS TO BUILD A VECTOR PROCESSING VERSION OF PCGPAKTM, THE PRECONDITIONED CONJUGATE GRADIENT PACKAGE OF SUBROUTINES FOR INTERATIVE SOLUTION OF LARGE, SPARSE, NONSYMMETRIC SYSTEMS OF LINEAR EQUATIONS. PCGPAK, WHICH IS CURRENTLY BEING MARKETED BY SCIENTIFIC COMPUTING ASSOCIATES, REPRESENTS A STATE-OF-THE-ART SOFTWARE TOOL FOR SEQUENTIAL PROCESSING ARCHITECTURES, AND ITS MODIFICATION FO ...

THE SUBSTITUTION OF POLYMERS FOR METALS AND OTHER MATERIALS IS OCCURRING AT AN INCREASING RATE IN SEVERAL U.S. INDUSTRIES (E.G., AUTOMOTIVE, AEROSPACE, COMPUTER). THE MOTIVATION IS THAT POLYMERS OFTEN HAVE SIGNIFICANT ADVANTAGES IN TERMS OF WEIGHT AND/OR COST. HOWEVER, THE DEGRADATION OF POLYMERS IS A LIMITING FACTOR IN MANY APPLICATIONS. THE THERMAL DEGRADATION OF POLYMERS IS AN IMPORTANT ISSUE I ...

IN DEVELOPMENT OF COAL-BASED ENERGY SYSTEMS, THERE IS AN ACUTE NEED FOR INSTRUMENTATION CAPABLE OF MEASURING FLOW RATES OF SOLIDS AND GAS IN GAS-SOLID SUSPENSIONS UNDER HIGH TEMPERATURE (UP TO 1700 DEGREE FAHRENHEIT) AND HIGH PRESSURE (UP TO 100 ATM) CONDITIONS. SEVERAL INSTRUMENTATION CONCEPTS HAVE BEEN OR ARE CURRENTLY UNDER STUDY (I.E., SONIC DOPPLER METERS, CORRELATION METERS, CAPACITIVE TRANS ...

WE PROPOSE TO INTEGRATE A POWERFUL INTERACTIVE SOFTWARE ENVIRONMENT FOR SCIENTIFIC COMPUTING AND VISUALIZATION WITH SUITES OF HIGH-QUALITY NUMERICAL SUBROUTINE LIBRARIES, INCLUDING PARALLEL AND VECTOR ROUTINES. THE ADVANTAGES OF THE PROPOSED SYSTEM INCLUDE RAPID AND EFFICIENT PROTOTYPING OF SCIENTIFIC CALCULATIONS, INTERACTIVE ACCESS TO NUMEROUS STATE-OF-THE-ART SUBROUTINE LIBRARIES, AND THE CREAT ...

Traditional weapon systems often fail to meet the requirements of close combat typical of the previously discussed engagement, where insurgents often blend in or store weapon amongst friendly or non-combatant forces, to shield them from precision strike munitions of a technologically superior force. This type of warfare has led to an increased focus on the use of less-lethal weapons, to reduce let ...

Nalas Engineering and Johns Hopkins University collaborated in a Phase I STTR program to study reactive mixtures of HI3O8 and nanocomposite fuels previously developed by the Weihs Group. These fuel/oxidizer mixtures are uniquely able to simultaneously produce heat and biocidal iodine gas, a combination designed to destroy biological weapons. The team at Nalas focused on evaluating conditions for p ...

LOG-POLAR COORDINATES HAVE RECENTLY BEEN SHOWN TO POSSESS SIGNIFICANT COMPUTATIONAL ADVANTAGES OVER TRADITIONAL CARTESIAN COORDINATES IN EXPRESSING TRANSFORMATIONS ASSOCIATED WITH DYNAMIC 3-D PERSPECTIVE IMAGERY. REDUCED PIXEL COUNT AND REDUCTION IN CALCULATIONS PER PIXEL SUGGEST THE FEASIBILITY OF COMPACT, HIGH-PERFORMANCE SYSTEMS NOT POSSIBLE WITH CARTESIAN SYSTEMS. RECENT THEORETICAL DEVELOPMEN ...
