Jet engine disk components are increasingly subjected to higher operating temperatures. To meet the demands of increasing thrust and higher operating temperatures, a newer generation of nickel based superalloys such as LSHR, Alloy 10, Rene104 and RR1000 are being processed with dual microstructure distributions. Fine grain, high strength, fatigue resistant bore properties are contrasted with co ...

ABSTRACT: In this STTR Tech-X corporation in partnership with the University of Washington will improve a commercial plasma modeling tool, Nautilus, for simulating high-temperature multi-fluid plasmas for problems such as the field reversed configuration, dense plasma focus and the plasma opening switch. Semi-implicit algorithms will be implemented in Nautilus so that the speed of light and elec ...

The overall objective of this STTR project is to develop a comprehensive CAD environment for design and optimization of antennas and arrays on complex platforms such as topsides of naval surface combatants. EMAG Technologies Inc. has teamed up with the University of Michigan to develop a novel solution for placement of antennas on such platforms using a number of new physics-based genetic algorith ...

ABSTRACT: Microscopy is a critical enabling technology for advancing our understanding of nature. Imaging nano-scale objects with light in the extreme ultraviolet (EUV) and soft x-ray regions of the spectrum has advantages over visible light for several reasons including: resolution, elemental specificity, and the ability to image internal structures. Coherent diffractive imaging (CDI) has been ...

Owing to a unique set of intellectual property and core expertise, this Phase II team, led by Traycer Diagnostic Systems, will build and characterize a packaged, 16x16 terahertz focal plane array (FPA) for broadband video-rate imaging at frequencies up to 1.3 THz. Traycer’s competitive advantage is based on its record-performing detectors, novel antennas, and array architectures that permit a d ...

Through the execution of our Phase 1 effort, Nutronics, Inc. and Montana State University developed an improved means to optimize the Pellizzarri cost functional for coherent imaging using digital holography. Our algorithm developed during the Phase 1 effort accelerates convergence times by a factor of 20-40 for the majority of scenarios evaluated. Our proposed Phase 2 effort has a two-fold focus: ...

The main objective of the proposed Phase II project is to leverage the technology of THz generation in resonantly-pumped quasi-phase-matched (QPM) GaAs structures, jointly developed by Stanford University and Microtech Instruments, Inc., and create a compact and power-efficient commercial THz source with a mW-level average power. This source will be continuously or step-tunable in the 0.5-3 THz ra ...

ABSTRACT: This proposal is concerned with the development of a novel failure initiation and progressive failure analysis modeling method for advanced composite structures, including the analysis of selected structural joints utilizing a statistically based micromechanics model embedded in a 3D non-linear finite element code. The method accounts for the interaction between out-of-plane failure and ...

The goal of BLUE is to identify the function or purpose of buildings using persistant surveillance video such as Constant Hawk or Angel Fire. In Phase 1, we developed preliminary algorithms demonstrating that functional recognition of buildings and other scene elements such as parking spots and doorways is possible, using both supervised and unsupervised techniques to define functional models of b ...

In Phase II, based on the Phase I success, we propose to research further enabling optimizations for a wider range of sensor applications than in Phase I. We will also implement the key optimizations to SAR found in Phase I within the SANE high-productivity array language and automatic parallelization tool chain. These optimizations have a wide application domain within sensor applications and bey ...
