Frontier Technology, Inc. and University of Rhode Island Physics department propose to develop innovative, scalable random number generators for use on multiple parallel computing architectures. Our Phase I effort will include a comprehensive assessment of currently available algorithms for parallel random number generation as well as the currently available tests designed to uncover statistical d ...

The occurrence of combustion instability has long been a matter of serious concern in the development of liquid-propellant rocket engines due to the high rate of energy release in a confined volume in which energy losses are relatively small. Positive feedback between the acoustic waves and unsteady combustion could lead to the destruction of an engine in a fraction of a second. The situation is ...

Complex software systems are typically developed by disparate engineering teams working concurrently. At the same time, software requirements are frequently dynamic, evolving even during active development cycles. Discrepancies between how software is defined and how it is implemented at the modular level can cascade into critical system errors when modules are integrated. More troubling is that i ...

Inlustra Technologies and the University of Notre Dame propose a Phase I STTR program that, combined with a subsequent Phase II effort, will result in methods for the scalable production of semi-insulating non-polar GaN substrates. These substrates will be utilized in the fabrication of high-power/high-frequency AlGaN-GaN electronic devices capable of reliable operation under high thermal load. ...

This is a proposal to develop a unique, robust, fieldable, gated, picosecond, digital holography system for characterizing dense particle fields under harsh conditions. Many powerful imaging methods have failed to fulfill this requirement because noise from multiple scattering buries the signal needed to acquire a useful image. Solutions to this limitation are very expensive, hard to implement, an ...

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 ...

Warfighters face overwhelmingly complex and uncertain situations in which they must make life-and- death decisions. Today"s information systems often overwhelm decision makers still further. Attention to results of cognitive science can contribute to the design of a new generation of systems that are far more helpful: based on knowledge of user roles, tasks, and context, systems can help proactive ...

Decision making is driven by context. Context can be hard to operationalize and harness to the design of decision support systems. Modern military task displays often omit important context which can lead to singificant errors. This problem is exemplified in undersea warfare and specifically contact management for safe littoral navigation. In littoral navigation, workload may be high and team memb ...

The goal of the Phase I project is to develop a COTS system into a modular unit for detection, tracking and classification of large marine organisms such as manatees and turtles. The Kongsberg Mesotech M3 Sonar is a 500 kHz multibeam that can resolve objects as far as 150 m. This compact system has been tested to detect Florida manatees by Dr. Kevin Boswell and will be used by well qualified marin ...

SciTec and Sandia National Laboratories (SNL) propose a multi-scale simulation architecture for generating optical signatures from missile intercept debris clouds based on output from hydrocode tools developed at SNL while furthering optical data exploitation from the library of Aegis Ballistic Missile Defense (ABMD) intercept test. This will require developing data-driven relationships for match ...
