For many programs, it would be desirable to fail fast in the face of attack in order to preserve confidentiality and integrity. We propose a tool to statically rewrite binaries to increase their fragility, adding this fail-fast property. We will operate on binaries to maximize the number of programs we can protect. Binary rewriting can be applied to any program without cooperation from the compile ...

CU Aerospace (CUA), teamed with the University of Illinois at Urbana-Champaign (UIUC), proposes to research, develop, and demonstrate thermal management simulation tools for next-generation two-phase cooling systems designed for transient high heat-flux naval applications. The software developed in this program can be used to evaluate advanced thermal management designs for critical emerging naval ...

Electron Beam Additive Manufacturing (EBAM) is a layer additive manufacturing technology capable of producing refractory metal (C103, Ta-10W) components from a computer generated 3D CAD model. These near net shaped preforms utilize significantly less material and require substantially less machining than the current process being used.

Research the use of laser powder bed fusion to provide a lower cost method to manufacture complex geometries in C103 and other refractory metals.

The objective of the proposed project is to develop a lightweight, robust, and modular system, capable of harvesting solar energy in areas with dense foliage cover in an effective manner. The system proposed will be able to reach a height of 100 feet above an average tropical forest canopy to deploy a solar array capable of generating 250 W under AM1.5G 1-sun illumination. In this proposal, MicroL ...

Existing ultraviolet laser diodes with wavelengths much shorter than 355 nm suffer from poor performance. This is partially due to limited research in this area, but a large part is also due to material and processing issues unique to deep UV lasers. New approaches to achieving III-Nitride UV lasers at wavelengths shorter than 355nm are needed to meet the Navys ambitious goals of having 1 W of CW ...

Additive manufacturing (AM) promises to be an innovative technology that can enable rapid manufacturing of complicated parts and greatly reduced cycle time. However, the AM process is complex and involves a large number of processing steps, each with its own set of uncertainties. These uncertainties compound through the AM build process, resulting in parts with widely varying properties across dif ...

MicroLink Devices proposes to integrate its novel, high-efficiency, lightweight, and flexible solar sheet technology to a small unmanned aircraft system (UAS) that will provide a significant source of power, enabling long endurance flights spanning one full day to several days of continuous operation. This will be a breakthrough technology that will enhance the performance and utility of the Navys ...

Additive Manufacturing (AM) promises to be an innovative technology that can enable rapid manufacturing of complex parts at greatly reduced cycle time. With the maturation of selective laser melting (SLM) AM technologies there is increasing interest in applying this manufacturing method to the production of aircraft structural components, many of which are made of high-strength stainless steels. H ...

The main focus of this research will be to develop effective modeling toolboxes to analyze CM current/voltage behaviors and fault conditions at any part of the power system in a cost and time effective way. The toolbox will assist with grounding strategies and enhance the baseline design. A CM equivalent circuit model [3] has been developed to analyze the CM current/voltage behaviors. In this work ...
