Two-electron reduced-density-matrix (2-RDM) methods represent all of the electrons in any molecule or material with only two electrons by replacing the wave function by the 2-RDM as the basic variable for quantum many-electron theory. The 2-RDM methods, developed by David Mazziotti at The University of Chicago with support from the Army Research Office, have polynomial scaling with system size, al ...

The objective of this proposal is to design a detailed curricula framework for an ITS and Connected Vehicle industry-recognized credential program. Titled Transportation Tech, the framework will serve as a basis for developing 3 levels of online credential training in each industry. The education and professional development of technicians in the ITS field is pivotal to the future of our nation’ ...

The objective of this proposal is to demonstrate the feasibility of developing a “Customer Based Mobility” application, named Liberty, for enhancing transportation options for vulnerable populations and senior citizens in rural and small urban communities. Utilization of technology for route optimization and customer trip booking in rural and small urban transportation agencies is currently ve ...

This project seeks to define the performance requirements for a wireless Digital Train Line (WiDTL) through definition of functionality and performance expected, and translating these into network equipment specifications and architecture that wireless network equipment manufacturers can build towards. The effort will include an in-depth review of wireless technology as it applies to sensitive and ...

Autorack cars transport one of the most valuable commodities – fully assembled Automobiles. Due to the longer and higher profile of an Autorack and the fact that heavy automobiles are loaded on to high deck levels, freight trucks with improved track-to-vehicle dynamics as well as higher speed capabilities are desired in anticipation of higher speed passenger service and shared corridors. Unique ...

ABSTRACT:Using lasers as signal carriers, FSO laser communications (Laser-Com) can provide a line-of-sight, wireless, high-bandwidth, communication link between remote sites. Because of the reduced scattering, long-wavelength infrared (LWIR) 8 13 um radiation possesses significantly better all-weather transmission than the shorter wavelengths in use today. The superior transmission through common ...

ABSTRACT: In Air-Force landing gear systems, high strength CuBe alloys are used in bushing applications where high wear resistance and strength is critical. Beryllium can be toxic and presents health concerns; removal from DoD weapons systems is likely, and the need for Be-free replacement materials is critical. QuesTek Innovations, a leader in the field of Integrated Computational Materials Engin ...

Absorber layers based on strained layer superlattice (SLS) composed of III-V compound semiconductors (e.g. GaSb and InAs/Sb) are a promising sensor technology for infrared imaging; however, dark currents and short carrier lifetimes in SLS are still significant problems. It is presently suspected that the short carrier lifetimes and some dark current arise due to a native point defect, possibly the ...

High performance HgCdTe infrared detector arrays operating at 77 K can be tailored for response across the infrared spectrum (1 to 14 micron and beyond), and are utilized in a variety of military and civilian systems for infrared imaging. Reducing cooling requirements allows integration in lighter and more compact systems. Good performance at higher operating temperatures can be provided by a syst ...

ABSTRACT:CU Aerospace (CUA) proposes the development of the Monopropellant Propulsion Unit for CubeSats (MPUC) thruster, a breakthrough complete propulsion system technology for CubeSats and other small satellites, because of its high performance, nontoxic chemical monopropellant and benign storage characteristics. MPUC pushes the envelope of existing propulsion technologies by significantly incre ...
