ABSTRACT: IllinoisRocstar LLC and Purdue University propose a framework that enables field assessment of particle size and shape for use in ultra-high performance concrete. We will implement portable scanning approaches for particle size measurement and combine this with high performance computer modeling to optimize altering particle size proportions. Critically, the framework will be implemente ...

ABSTRACT: A high-fidelity computational electromagnetic solution will be developed that directly solves Maxwell"s equations in order to calculate radar returns from complex, electrically large objects in motion, such as wind turbines with rotating blades. The solution will include propagation effects from terrain and atmosphere, multipath between object parts, and the details of interior and ext ...

ABSTRACT: Confronted by a vast quantity of data, presented piecemeal, sporadically and at varying levels of detail, the human analyst is often overwhelmed when trying to effectively monitor even medium-sized areas of interest. Offline, there is a wealth of data, resolution, and time to pick through and find activities of interest. Given a large amount of high resolution data, we can simulate situ ...

A parallel random number generation suite that generates, dynamically, millions of parallel pseduorandom number streams suitable for consumption by high performance computing (HPC) applications on various platforms will be implemented, tested, and provided to Government, academic and private HPC users for their evaluation and use. The software will be tuned for scalability, repeatability and effic ...

Detecting light at the single photon level is a fundamental measurement function that is useful in a wide variety of applications, including such diverse fields as quantum communications, laser ranging, and biological spectroscopy. Avalanche photodiode based single-photon detectors are convenient solid-state devices that do not require cryogenic cooling. We will build avalanche photodiode based si ...

Recently, the availability of the high performance rare earth based magnets (Nd-Fe-B and Sm-Co) was jeopardized due to the Chinese monopoly of rare earth production, which undermines our national security and competitiveness in the defense and clean energy sectors and creates a strategic vulnerability for the United States. This STTR proposal aims at developing the next generation of rare earth f ...

This Phase I program is focused on enhancement of the performance of MgZnO based solar blind detectors. MgZnO alloys have superior optoelectronic properties with bandgaps suitable for solar blind detection. Issues related to doping and miscibility will be addressed. This will involve the use of advanced MOCVD and MBE growth techniques and consideration of both Schottky and p-n junction devices. No ...

ABSTRACT: In order to achieve precise guidance, navigation and control in reentry vehicles, aerodynamic shape must be accurately known throughout the flight trajectory. In the Phase I program, real-time, temperature compensated ultrasonic measurements of surface recession of TPS materials was demonstrated. Using sensors mounted on the non-heated surface, recession was measured with unprecedented ...

ABSTRACT: Mycotoxins are toxic secondary metabolites of molds and fungi, many of which are pathogenic to humans. In general, mycotoxins enter the body through the skin, digestive tract, or through respiration. Exposure to a few milligrams can be lethal. Mycotoxins have a high likelihood of being weaponized, due to their ease of large scale production. One possible way to counteract the effec ...

ABSTRACT: The chalcogenide based ion-conducting memristor has been shown to be an effective element as the core of a simple neuromorphic computing circuit. The response of the computing circuit is the result of weighted external stimuli, the current state of the device, and the history of exposure by the device to the stimuli. A highly specialized version of the device, as developed by the Advanc ...
