Scalable manufacturing of micro-engineered MRI contrast agents has the potential to increase the specificity and resolution of imaging techniques, while reducing morbidity. Currently, techniques used for making such particles are expensive and labor intensive. In Phase I, Weinberg Medical Physics will validate techniques for rapid, massively parallel fabrication of microscale contrast agents (incl ...

The objective of this project is to demonstrate a resonant scan lens (RSL) that increases the uniformity of beam scans projected from resonant optomechanical systems. While resonant optomechanical systems generate high-speed beam scans, large mechanical displacements, and robust operation from miniature form factors, scans projected from such systems lack uniformity across the field-of-view (FOV). ...

methyst Research Inc. will design, fabricate and test a high uniformity, large area, low noise infrared trap-detector detector for the 1- 4.5 μm wavelength range. This state of the art detector will have a large area (e.g., 1-1.8 cm diameter active area) with a spatial variability of internal quantum efficiency of less than 0.1 % between 1 μm and 4.5 μm. In addition, the internal quantum effici ...

This Phase II project will continue the prototype development of a pharmaceutical spray quality audit system. The spray quality audit system will estimate the planar mass distribution, mass flux, and drop size of pharmaceutical sprays that are used in functional coating applications and inhalers. A prototype tomography system will be designed and fabricated and evaluated using various fluorophore.

Thermal Stir Welding (TSW) advances the more conventional Friction Stir Welding (C-FSW) process by separating the primary process variables of metal stirring and forging from the control of the workpiece temperature. The independent heating is obtained by placing an induction coil in front of a specially modified tool to bring the workpiece to the appropriate joining temperature. However, studie ...

A fast-paced continual increase on the ratio of CPU to memory speed feeds an exponentially growing limitation for extracting performance from HPC systems. Ongoing developments and trends make it clear that this ratio will keep increasing over the next decade. Breaking this memory wall is one of the most important challenges that the HPC community faces today. In this project we introduce novel and ...

NASA researchers have been studying ground-based conflict detection and resolution for at least ten years. Under the tool proposed herein, these researchers will be able to evaluate both the performance impact and the environmental impact. The environmental impact is important for obtaining approval to move the ground-based conflict detection and resolutions algorithms to higher Technology Readi ...

Cognitive radio technology provides spectrum agility to increase the level of cognition and automation. However, spectrum agility alone is not enough to achieve reliable communications for space networks. Mission success often requires network agility across the protocol layers for environmental awareness and autonomous reconfiguration. This is still an unsolved problem. Specifically, multi-hop wi ...

Today's mission designers rely on state of the art tools with modern GUI elements and real-time 3D interactive graphics to visualize their trajectories and orbit control strategies. One such tool, NASA GSFC's General Mission Analysis Tool (GMAT), offers advanced mission design and optimization capabilities with a flexible GUI. However, its current 3D graphics are lacking in both the quantity and q ...

Conventional SAR operates in the Stripmap mode. Wide unambiguous swath coverage and high azimuth resolution pose contradictory requirements on the design of SAR systems. A promising technique to overcome this limitation is Digital Beam-Forming (DBF) on receive where the receiving antenna is split into multiple sub-apertures. This provides the capability of forming multiple beams via post-processin ...
