Modern processor design is trending increasingly toward multicore architectures. This is problematic for programmers because writing a correct parallel program is known to be difficult compared to writing the equivalent sequential program. Additionally, a wide body of sequential code has already been developed that cannot exploit the power offered by these new cores because it was written in a s ...

Many military applications require efficient optical sources producing several to hundred watts in continuous-wave (CW) or quasi-continuous-wave (QCW) operation at room temperature (RT) in the MWIR (3-5 micron) and LWIR (8-12 micron) regions. While QCLs have become the sources of choice in these spectral regions, the only realistic option to attain hundred-watt power level with good beam quality i ...

In the Phase I portion of this STTR, Securboration and renowned multicore expert Dr. Frank Mueller from North Carolina State University designed, developed, and benchmarked the proof-of-concept Pico-kernel Adaptive and Scalable Operating-system (PICASO) for many-core architectures. The Securboration Team took a scientific, experimentation-based approach to identifying and resolving shortcomings wi ...

ABSTRACT: It is proposed to demonstrate a surface fabricated using thin film metamaterial designs that can exhibit rapidly varying angular as well as spectral emissivity profiles. The technology enables specification of desired angular pattern at design time, and can be fabricated in large area formats. BENEFIT: The proposed technology will allow directional control of thermal radiation in app ...

ABSTRACT: Under the first phase of the program, Plasmonics Inc. and Sandia National Laboratories investigated a range of surfaces that yield non-Lambertian emission profiles in the thermal infrared. The second phase of this program will further maturate the designs developed in the first phase of the program. With the vast majority of the analytical work complete, focus in the second phase will b ...

Quallion LLC proposes to continue development of its reference electrode technology into a commercial scale prototype and partner with the University of South Carolina to develop a life prediction model for cells cycled at high depths of discharge. In Phase II, Quallion will refine its reference electrode design based on lessons learned in Phase I, incorporate a reference electrode into commerc ...

We propose to continue the development of software designed to model the propagation of light pulses through atomic media by including the capability to model propagation in optical cavities with active laser media, among other improvements. The software will be used to design and analyze a gyroscope based on the Sagnac effect that achieves enhanced sensitivity by employing a highly dispersive ato ...

ABSTRACT: The proposed research will demonstrate feasibility of a high temperature insulating, load bearing thermal protection system (TPS) using a hybrid composite technology. This program will incorporate a hierarchically porous ceramic core material in a sandwich structure with a conventional polymer matrix composite (PMC) and ceramic matrix composite (CMC) to fabricate an enhanced TPS. This m ...

ABSTRACT: The goal of this phase II proposal is to develop a commercial platform for printing high performance, single-walled carbon nanotube transistor circuits on large-area plastic substrate. Automated processes will be developed for the room temperature printing of metal, semiconductor, and dielectric materials with micron-scale alignment accuracy. The transistor performance will be enha ...

ABSTRACT: In Phase II, we will fabricate a SQUID array antenna. We will develop cryopackaging and control electronics for these devices. We integrate the device onto a cryocooler and build a laboratory prototype. We will then have all of the building blocks to build a fieldable prototype in Phase III. BENEFIT: Military Application: Microwave Communication Systems for ISR. Commercial Application ...
