Award Data

Existing riverine drifters are passive devices designed to capture, store and transmit river flow and bathymetry information. Problems inherent with passively drifting devices include the inability to maintain uniform cross-stream spatial coverage and lost drifters due to unintentional grounding and entanglement with various hazards present in a typical river environment. This proposal outlines a ...

We propose to design, develop, implement, simulate, and demonstrate an autonomous control and sensing system for the safe vertical landing of autonomous aerial cargo delivery system (ACDS). The landing site is expected to be unprepared mountain sides with slopes up to 15 degrees and rough terrain containing rocks and brush. We also plan to reduce the amount of ground equipment required to operate ...

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 ...

Advances in electronically controlled injection technologies for diesel engines have provided a method to improve medium- to heavy-duty engine performance through increased injection pressures, multiple injections, and injection rate shaping. Although these injection systems have been primarily limited to larger engines, the ability to rapidly and precisely meter fuel for smaller engines is partic ...

In miniature gas turbines for UAV applications, traditional bearings exhibit a typical lifetime of only 25 hours due to excessive axial loading. Mainstream proposes to use a passive, permanent magnet thrust bearing to alleviate this problem and increase service life to over 1000 hours. Since this type of bearing is non-contacting, it can operate at very high rotational speeds with minimal heat gen ...

Intelligent Fiber Optic Systems Corporation (IFOS) and Georgia Tech propose a fiber Bragg grating (FBG) integrated sensor system capable of measuring the pipe wall "breathing mode" in order to infer the fluid-borne sound pressure level (SPL) in a pipe. The proposed new measurement technique makes it possible to externally measure the fluid-borne sound level in a noisy piping system. The state-of-a ...

IFOS will demonstrate the feasibility of a minimalistic, yet powerful, distributed network of piezoelectric actuators and ultrasonic wave detecting fiber optic Bragg grating (FBG) sensors interrogated by a high frequency parallel processing FBG interrogator together with innovative mathematical and computational algorithms to process, store and visualize (via damage index maps) massive amounts of ...

Together with our research institution partner, the University of Central Florida (UCF) Institute for Simulation and Training (IST), Sonalysts is pleased to submit this proposal to investigate the feasibility of creating a Service Oriented Architecture (SOA) framework for correlation and fusion algorithms that drive scenario generation across many information domains (communication, imagery, track ...

Iris Technology, in collaboration with Georgia Tech and Raytheon, proposes to perform advanced 3D CFD modeling to guide the architecture selection for a tactical 4K Cryocooler. Iris will lead the System Design and Program Management efforts. Georgia Tech is the lead organization on the Analysis. Raytheon is providing the underlying mechanical cryocooler technology. The preliminary technical base ...

Acellent Technologies Inc. and Prof. F. G. Yuan at North Carolina State University (NCSU) are proposing to develop a Hybrid Distributed Sensor Network Integrated with Self-learning Symbiotic Diagnostic Algorithms and Models to determine materials state awareness and its evolution, including identification of precursors, detection of microdamages and flaws near high stress area or in a distributed ...
