Impact Technologies, in cooperation with Dr. Mohammed Daqaq from Clemson University, propose to develop a magnetostrictive materials based device for harvesting energy from mechanical vibration. The energy harvesting device will harness power from ship-hull vibrations in order to power sensing devices. This technology will be a key enabler for improved structural and machinery health management. K ...

For Unmanned Aircraft Systems (UAS) to operate seamlessly in both the U.S. National Airspace System (NAS) and abroad, it will be crucial that they possess a sense-and-avoid (SAA) capability that can ensure safe operations among maneuvering, non-cooperative aircraft. Numerica Corporation, in partnership with Johns Hopkins University, proposes to develop a set of algorithms to model the uncertaintie ...

Software is rarely written entirely from scratch. Typically, third-party commercial off-the-shelf (COTS) components are integrated into larger software systems used both in the commercial sector and in critical infrastructure. Third-party components often come in binary form, e.g., as dynamically linked libraries, Active X controls, or plain executables. That is, the source code for those componen ...

Current software development and testing methodologies are inadequate for validating software in mission-critical applications. As Dijstra famously stated: "testing can be used to show the presence of bugs, but never to show their absence." When lives and national security is at stake, there is a need for mathematically rigorous techniques that can verify the absence of bugs. We propose to devel ...

Under this STTR, Imaging Systems Technology (IST) in cooperation with Georgia Institute Technology (GIT) will develop and mature models to predict mechanical properties of refractory alloys with an eye toward tailoring these alloys for specific applications. In particular, this research will focus on addressing core aspects of Integrated Computational Materials Engineering (ICME) as it applies to ...

The objective of the work described in this proposal is to aid in the advancement of Mo-Si-B alloys for use in high temperature applications such as hot gas stream components in turbine engines. Such alloys are being characterized for their monotonic tensile properties in tension and compression as well for their creep resistance. Likewise, multiphase Mo-Si-B alloys have been studied in terms of m ...

Trauma is a leading cause of both military and civilian mortality, accounting for roughly 10% of all deaths worldwide. Coagulopathy (disturbance of the physiologic balance between bleeding and clotting) is observed in 25% to 36% of trauma patients and significantly increases mortality. Trauma-related coagulopathy typically involves dysfunction or depletion of coagulation factors, platelets, fibrin ...

Integrally bladed rotors (IBR), also called blisks, are becoming increasingly common in the compressor and fan sections of modern turbine engines. The integration of the blades and disks into a single part has the advantages of reduced part count, reduced weight, increased reliability, and increased performance. However, a drawback of this technology is that individual blades cannot be easily repl ...

Images with associated text are now available in vast quantities, and provide a rich resource for mining for the relationship between visual information and semantics encoded in language. In particular, the quantity of such data means that sophisticated machine learning approaches can be applied to determine effective models for objects, backgrounds, and scenes. Such understanding can then be used ...

TDA and its University partner, Cornell University, first address the stress assisted corrosion crack growth from concurrent multi-scale modeling through atomistic simulations in order to formulate and calibrate mesoscale Peridynamics model. Initially, the multi-scale CADD simulations will utilize reactive force field potentials for the 7075-T6Al in water to simulate stress corrosion cracking and ...
