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: SYMPLECTIC ENGINEERING CORP Topic: N10AT028
Turbine efficiency improves with increased operating temperature. Consequently, the rim zone of disks operates at high temperatures where creep is the main concern. The bore and web zones operate at lower temperatures, where strength is the driving design criterion. Procedures to produce disks that can meet both demands include dual heat-treatment and hybrid disks. A thin transition zone forms in ...STTR Phase I 2010 Department of DefenseNavy
SBC: SYMPLECTIC ENGINEERING CORP Topic: AF08T013
The objective of this project is to develop a practical finite element-based simulation of spin-pit tests of disks. The performance of disks in spin-pit tests critically depends on localized effects, such as residual stresses, dislocations, and microstructure gradients. Therefore, a two-scale modeling approach is adopted. At the global-scale, the disk is represented by means of finite elements wit ...STTR Phase II 2010 Department of DefenseAir Force
SBC: TRANSITION45 TECHNOLOGIES INC Topic: A10AT001
This STTR program proposes to exploit the tremendous benefits that could be offered by the development of ultra fine grain steel alloys for application to the production of high performance components for military rotorcraft applications. A severe plastic deformation technology based on isothermal forging technologies will be explored here. The goal is to demonstrate a practical, production leve ...STTR Phase I 2010 Department of DefenseArmy
SBC: JMSI, INC Topic: AF09BT18
The need for faster highly resolved solutions coupled with the advent of General Purpose Graphics Processing Unit (GPGPU) architectures and the development of GPGPU algorithms at the University of California, Davis present an opportunity that JMSI Inc. proposes to leverage by developing algorithmic and software solutions for GPGPUs in “Innovative CFD Algorithms, Libraries & Python Frameworks for ...STTR Phase I 2010 Department of DefenseAir Force

SBC: NUMERICA CORPORATION Topic: AF09BT02
Accurate and timely surveillance of objects in the near-Earth space environment is becoming increasingly critical to US national security. One of the main difficulties in this domain is efficiently and accurately modeling trajectories of the vast number of objects in orbit around the Earth. The orbital trajectory of a single object is typically modeled as a second-order system of equations which ...STTR Phase I 2010 Department of DefenseAir Force
Realistic State and Measurement Error Uncertainty Computation and Propagation for Space Surveillance and ReconnaissanceSBC: NUMERICA CORPORATION Topic: AF09BT11
Space surveillance is the component of space situational awareness focused on the detection of resident space objects (RSOs) and the use of multisource data to track and identify space objects. While the propagation of the states of RSOs has been investigated extensively over the last fifty years, the correct propagation of their covariance or the more general (non-Gaussian) probability distribut ...STTR Phase I 2010 Department of DefenseAir Force
SBC: NUMERICA CORPORATION Topic: AF09BT09
A mathematical framework for detection and classification of weak, distributed patterns on computer networks is proposed. The framework will provide rigorous methods for understanding performance bounds and optimality of intrusion detection methods, while also providing concrete and implementable algorithms. The algorithms will find immediate application in cyber-security efforts, as well as mor ...STTR Phase I 2010 Department of DefenseAir Force
SBC: NEXTGEN AERONAUTICS, INC. Topic: N10AT021
A team led by NextGen Aeronautics Inc., and working with San Diego State University proposes the development of redundant wideband antennas that are embedded in composite armor structures The planned work builds upon the team’s extensive prior experience in conformal load-bearing antenna structures (CLAS), antenna design, and metamaterials. The proposed antenna is a combination of concepts that ...STTR Phase I 2010 Department of DefenseNavy
