ABSTRACT: Multidimensional simulation of plasmas will be critical to the design of high voltage and high energy density devices over coming decades. Individual fluid simulation codes are presently limited to one or perhaps two of three plasma models: the higher densities and longer time scales of magnetohydrodynamics (MHD), the lower densities and shorter time scales of extended MHD (XMHD), and ...

ABSTRACT: We propose to develop and validate a strongly-coupled non-equilibrium plasma simulation model. Strongly coupled plasmas occur in a wide range of physical situations impacting a wide range of research and development areas connected to Air Force technology. The simulation model proposed here is based on the particle-in-cell (PIC) methodology, which has recently been validated by the pro ...

ABSTRACT: TechFlow Scientific, a division of TechFlow Inc., along with its teaming partner, the University of New Mexico, is pleased to propose a three-phased research and development effort for the design, development, fabrication, and testing of miniaturized functional cellular elements that can be incorporated into an ensemble based mesoscopic framework. The TechFlow team comprises leading sci ...

We propose a self-organized chaotic attractor based CMOS/Memristor circuit framework called Self-Evolvable-Logic-Fabric (SELF) for autonomous motor control. We propose to demonstrate SELF's ability to spontaneously evolve algorithmic pathways to control a robotic arm to catch a ball utilizing visual and proprioceptive feedback while varying parameters that increase the complexity and difficul ...

High power microwave (HPM) sources have been developed over the past few decades for many important DoD missions ranging from electronic warfare to intentional EMI to impulse radar. One important area of development for HPM devices is ballistic missile defense (BMD). HPM systems and techniques may be able to disrupt, damage, or destroy critical elements of adversary ballistic missile systems, re ...

ABSTRACT: Military applications for the use of directed electromagnetic energy seek to disrupt electronic systems by exploiting non-linearity in semiconductors. While current mode second breakdown is a thermal non-linearity often exploited, it has been demonstrated that for a broad class of semiconductors RF/HPM signals at the interface will couple to protective diodes and other diode structures ...

ABSTRACT: MO-SCI Corporation and Missouri University of Science and Technology have developed and evaluated fusion welding technology applicable to ultra-high temperature ceramic (UHTC) composite joining during a Phase I ceramic joining program. This Phase II program will improve arc and reactive plasma arc welding techniques and consumables to improve joint quality. Work in the Phase I resulted ...

ABSTRACT: High energy density capacitors are required for practical implementation of GW-class pulse power systems on mobile platforms. In response to this need, TPL has established unique dielectric and capacitor capabilities. Revolutionary materials, designs and manufacturing processes have been developed for power sources that have potential for an order of magnitude reduction in mass and vo ...

ABSTRACT: The objective of the Phase II effort is to extend the mathematical model investigated in the Phase I to include wind speed as well as temperature modeling, continue its development for a University of Notre Dame Wind Tunnel Facility, and demonstrate utility by adopting the model to a government facility specified by AFOSR. Specifically, the Phase II will include developmental work in ma ...

ABSTRACT: The proposal outlines work and time tables associated with finalizing the development of wear model concepts developed in Phase I work to predict the wear of two materials sliding with respect to each other while being subjected to high velocities and/or high pressures. In parallel with this, a severe wear bench test fixture design will be finalized, built, and utilized to validate the ...
