The primary objective of this STTR is to develop thick, high-temperature superconducting (HTS) multi-layer heterostructures for high-power handling microwave devices and with reduced nonlinearities. Building on the resources of Neocera’s materials research on HTS heterostructures and MIT Lincoln Laboratories vast knowledge on nonlinear behavior of HTS films at microwave frequencies, this STTR P ...

Next Century Corporation and the University of Washington’s Department of Atmospheric Sciences propose development of the Micro-Meteorological Modeling (M3) system with the goal of rapidly performing high-resolution atmospheric dispersion modeling, ideally down to the microscale level, with a high degree of accuracy and confidence. Our M3 graphical user interface will provide the user with a hi ...

Previous studies have shown that superhydrophobic surfaces have skin-friction drag reducing properties in the laminar flow region, but not in the turbulent flow region. The drag reducing properties of superhydrophobic surfaces are recognized to result from air voids trapped in the surface, and the apparent lack of effectiveness in the turbulent flow region could result from: (1) lack of robust air ...

In this Phase I project Pharad and UCLA propose to create new physically small, electrically large HF antennas for vehicle-mount and man-portable applications. We will utilize a combination of antenna size reduction techniques: volumetric engineering; fractal structures; and slow-wave structures to realize novel small, efficient 2 - 30 MHz radiators that meet the size requirements of 500 cubic ce ...

We propose to prove the feasibility of using time domain terahertz (THz) non destructive evaluation (NDE) to inspect turbine blade thermal barrier coatings (TBC). High speed, non contact THz inspection will be useful both during the manufacturing process, during maintaince, and during recoating. Low thermal conductivity ceramic coatings that are deposited on Ni-alloy turbine-engine blades to pr ...

A new approach is proposed for high fidelity analysis of aeroelastic characteristics of integrally bladed rotors. This new multiscale approach for nonequilibrium flow path analysis will yield high fidelity solutions including all turbulence scales at a fraction of the computational cost of RANS. Integration of this advanced capability within an existing multidisciplinary, multifidelity, transien ...

It has been shown that hydrophobic surfaces can reduce skin-friction drag in micro-fluidic devices. During Phase I research, we will fabricate and test a high performance durable hydrophobic surface coating created by a simple, cost-effective, and environmentally friendly method. This coating could have significant effects on skin-friction drag reduction and/or transition delay in boundary layers. ...

The proposed work will provide highly reliable electrical machinery systems by developing fault diagnostics, prognostics, and self-healing control capability. In most power systems, individual components have their own fault protection controls built in. The fault protection is not controlled by the larger system power management controls. These component level controls are designed to protect ...

The Cell processor architecture represents a significant shift in deeply coupled multi-core processor architecture. In the first implementation, the Cell Broadband Engine (CBE) has broken new ground in clock speed, density and power dissipation. By creating a design optimized for a specific class of algorithms, the CBE can deliver peak performance of over 250Gflops and has been measured with susta ...

Modern flight simulators utilize combinations of motion, visual stimulation, and occasionally tactile body stimulation. Despite advances in these fields, simulators remain limited in the amount and type of motion simulation they can impart to a pilot. Direct vestibular stimulation can generate continuous sensed motions, and therefore holds promise for improving flight simulators by incorporating ...
