The SBIR.gov award data files now contain the required fields to calculate award timeliness for individual awards or for an agency or branch. Additional information on calculating award timeliness is available on the Data Resource Page.
SBC: Metacomp Technologies, Inc. Topic: AF12BT15
ABSTRACT: The proposed work aims to build a physics-based rapid turnaround simulation capability for resolving combustion dynamics in liquid rocket engines operating at trans-critical and supercritical flow regimes. The methodology will explore both Reduced-Order Methods and Reduced-Basis Methods as potential candidates for efficient unsteady flow simulation, data storage and retrieval, and data ...STTR Phase I 2013 Department of DefenseAir Force
SBC: HYPERCOMP INC Topic: AF12BT15
ABSTRACT: Stability phenomena that are of vital interest in liquid rocket motor development involve a confluence of diverse physics and interactions across many system components. Any comprehensive, self-consistent numerical model is burdened by a very large computational mesh, stiff unsteady processes which limit permissible time step, and the need to perform tedious, repeated calculations for a ...STTR Phase I 2013 Department of DefenseAir Force
SBC: APPLIED MATHEMATICS, INC. Topic: A13AT009
Mathematical models of physical and biological systems contain parameters that need to be estimated from measured data. Models with parameters distributed probabilistically require the estimates of a probability measure over the set of admissible parameters. We propose to use frequentist-based approaches for non-parametrically estimating probability measures that describe the distribution of par ...STTR Phase I 2013 Department of DefenseArmy

SBC: DESERT STAR SYSTEMS, LLC Topic: N10AT034
Small combat dive teams require a situational awareness capability that combines robust, low probability of detection (LPD) communication with navigation/tracking functions. The project will result in a compact terminal for underwater acoustics based communication, navigation and tracking. The Diver Messaging and Navigation Terminal (DMNT) will be rugged and easy to use, warranting a description ...STTR Phase I 2010 Department of DefenseNavy
SBC: YOTTA NAVIGATION CORP Topic: N10AT034
Yotta Navigation and The Ohio State University propose to develop a complete diver text messaging and locator system. The system will securely transmit preformatted and free-text messages, and will be able to accurately determine range and bearing, at distances of up to 1000 meters. This system consists of two major components. An ultrasonic cylindrical array, mounted on a swimmer delivery vehicl ...STTR Phase I 2010 Department of DefenseNavy
SBC: MZA ASSOCIATES CORP Topic: N13AT001
MZA partnered with the University of Notre Dame proposes to conduct high-fidelity computational fluid dynamics (CFD) simulations providing volumetric time-resolved aero-optical disturbance modeling for rotary-wing aircraft flow dominated by wing-tip vortices. We will develop detailed wave-optics models of a baseline Navy helicopter beam director including engineering-level simulations of the beam ...STTR Phase I 2013 Department of DefenseNavy
SBC: Vista Partners LLC Topic: A12aT029
The neurocognitive health of U.S. service members plays a vital role in the defense of the United States. It is critical to a service member"s effectiveness, to force readiness, and it is a key component of a service member"s successful reintegration into family life and society following deployment. Increased rates of mild traumatic brain injury (mTBI) and psychological health problems experien ...STTR Phase I 2013 Department of DefenseArmy
SBC: ITN ENERGY SYSTEMS, INC. Topic: A10AT023
This Small Business Technology Transfer Research program will develop narrow band plasmonic resonant cavity filters with integrated microbolometer sensors operating in the long wave infrared (LWIR) atmospheric transmission band for IR absorption measurements of low concentration chemicals. IR spectroscopy can identify a wide range of contaminants, including chemical/biological warfare agents, exp ...STTR Phase I 2010 Department of DefenseArmy
SBC: NEXGENSEMI CORPORATION Topic: AF09BT35
Graphene has become one of the most promising new materials to form semiconductor devices and microelectronic interconnects. NexGenSemi Corporation in collaboration with Sandia National Labs will develop a “Patterned Graphene Interconnect (PGI) and material modification for nanofabrication of transistor devices. This process resolution will dip deep down into the state-of-the-art technology no ...STTR Phase I 2010 Department of DefenseAir Force
