While the efficiency of x-ray sources is defined by the laws of physics, present day sources do not take full advantage of those laws. Other materials thant tungsten are not only more efficient in producing bremsstrahlung, but have "characteristic" x-rays that can make the beam harder instead of softer (as in the case for tungsten). Today's tubes also do not use optimum angles for the incident e ...

To advance scientific and medical understanding of blood chemistry, we propose to develop modern medical simulation software that will be of use in predicting outcomes of medical interventions. For example, the chemical reactions between hemoglobin, oxygen, carbon dioxide, and electrolytes that occur in blood are essential to understanding human physiology, but still confuse students at many leve ...

Mission Support proposes to develop a compact, self-contained neutron spectrometer for MeV neutrons that will be suitable for the detection of the nitrogen, oxygen and carbon components in explosive materials. Neutron-resonance-radiographic techniques will be employed to detect the presence of these materials through their distinctive total-neutron-cross-section resonances. The detector insures ...

Disability is the nation's largest public health issue; with over 35 million Americans experiencing disability and annual disability-related costs exceeding $170 billion. Planning for the efficient and equitable allocations of state and local rehabilitation services has generally been inadequate, however. Geographic information systems (GIS) approaches have the potential to dramatically improve ...

The Army has identified a need for process innovations that would support the production of components for light weight vehicles out of advanced materials. The use of advanced, lightweight structural materials in vehicular applications presents an opportunity to enhance the effectiveness of Army units. Through more effective energy utilization, fuel will be conserved, which will simplify the log ...

An effective removal of paint from many surfaces can result in increased safety and reduced maintenance cost for many systems. The ideal paint stripping system should; 1) easily strip paint from various structures, 2) allow safe operation and safe removal of paint hazardous by-products (e.g. lead paint dust), 3) not damage the surface, and 4) by simple and reliable for manual and automated operati ...

The efficiency, maintenance cost, and service life of off-highway vehicles can be drastically improved with the development of a heat exchanger precleaner. Development challenges include ease of integration with present and new vehicles, the device compact size, high contaminates removal efficiency, low initial and maintenance cost, and high reliability. The objective of Phase I of this project is ...

In this effort we propose to investigate various techniques for efficient and rapid CAD design of printed circuit antennas and associated circuit components. While the design of single microstrip patch antenna is relatively well developed, the same can not be said for arrays and antennas mounted on complex structures, especially at high frequencies where the quasi-static models are not accurate a ...

Open burning/open detonation (OB/OD) operations for the disposal of obsolete, defective, and waste military energetic materials, such as propellants, explosives, and pyrotechnics now require emissions data to support RCRA subpart X permit applications. Many of the current analytical methods used to obtain these data, such as gas chromatography/mass spectrometry and supercritical fluid chromatogra ...
