Ziva Corporation in collaboration with UCSB will develop a directly modulated polarization switching laser based on the Vertical Cavity Surface Emitting Laser (VCSEL) geometry with a 3dB frequency of at least 10 GHz. This will be a major breakthrough in the ability to cost effectively fabricate directly modulated lasers (even in 2-D arrays) with polarization diversity which has hitherto been only ...

Hi-Z Technology, Inc. (Hi-Z) and the University of California San Diego propose to adapt Hi-Z"s innovative Quantum Well (QW) thermoelectric (TE) technology to develop a TE cooler for the Army"s base camp tents. The cooler is to be embedded in the flexible

The proposed effort will further refine the adaptive model-based estimation and control guidance law developed during the Phase 1 effort to work in a two-tier algorithm with an agile, game-theoretic guidance law that is immune to the acceleration of the target. The two-tier approach is used to bring the intercept vehicle close to the target while conserving fuel but still obtains good minimal mis ...

Synthetic scenario-based training of Navy personnel in the use of Navy SIGINT/IO systems has helped to reduce training costs, and it has enabled the personnel to be trained in an environment that sufficiently approximates real-world situations that could not otherwise be accomplished within the classroom. However, scenario development is highly complex and involves a great deal of human effort and ...

ABSTRACT: The real-time implementation of controls in nonlinear systems remains one of the great challenges in applying advanced control technology. Often, linearization around a set point is the only practical approach, and many controllers implemented in hardware systems are simple PID feedback mechanisms. To apply Pontryagin"s principle or Bellman"s equation using conventional hardware and a ...

ABSTRACT: Based on our success in developing the world first commercial high power femtosecond fiber laser system and our leading technology development in ultrashort pulsed fiber laser and nonlinear fiber optics, PolarOnyx proposes, for the first time, a compact all fiber based high power (>kW) mid-IR supercontinuum source (1-5 micron) to meet with the requirement of the AF solicitation AF09-BT0 ...

ABSTRACT: This effort focuses on development of efficient algorithms for the simulation of propagation and scattering of electromagnetic fields within and around structures that (i) Consist of complex combinations of penetrable materials as well as perfect and imperfect conductors, and, (ii) Possess complex geometrical characteristics, including open surfaces and metallic coatings, as well ...

The program will develop a prototype Autonomous Helicopter Rugged Operations Controller (AHROC) supporting autonomous approach, landing, takeoff, departure and navigation in sloped, rugged terrain in a GPS denied environment. The AHROC system utilizes dual color camera inputs. Passive image processing functions provide: 1) Aircraft localization using a reference digital elevation map, 2) The gener ...

In Phase II, Solute Consulting will produce a prototype robust collaboration capability for Navy Command and Control,"Navy Wave"with the following technical objectives: 1 - Implement and demonstrate a federated, multi-server, Navy Wave prototype, 2 - Simulate Disconnected, Intermittent, and Limited (DIL) network connectivity issues, and demonstrate the ability to adapt to these conditions, without ...

This work will develop and validate a high-fidelity LES combustion model based on Flamelet Progress Variable approach for accurate prediction of high-speed turbulent combustion. The flamelet-modeling paradigm facilitates consideration of detailed reaction chemistry and complex turbulence-chemistry interaction, which is critical for high-speed hydrocarbon combustion. A work plan is proposed that in ...
