75004B If hydrogen is to be used as an environmentally-friendly fuel, hydrogen production costs must be lowered and carbon dioxide, a by-product of hydrogen production, must be separated for sequestration. This project will develop a membrane process to recover hydrogen and separate carbon dioxide from steam-methane-reformer pressure-swing-absorption plants. The process should increase hydrogen ...

Successful training in complex environments is normally accomplished through the interaction of a trainee and a skilled expert, but due to resource constraints, experts’ use in training can be problematic. Using an optimal model of task performance subject to human constraints may be a more efficient way to develop models of skilled human performance for use in training, especially since optima ...

MicroAssembly Technologies and Lawrence Livermore National Labs aim to develop low-cost MEMS spatial light modulators for adaptive optics correction and vibration/jitter control. MEMS SLMs can provide significant Strehl ratio improvements. However, available devices are severely limited by fabrication technology, resulting in low yields and high costs, which is prohibitive for most military appli ...

An OmniGuide fiber is a hollow-core fiber which employs a dielectric omnidirectional mirror to keep light confined to its core. These novel fibers are ideally suited for ultra-low loss optical transmission and for flexible delivery of high power lasers. Prior to and during our Phase I effort, we have developed a wide range of tools to simulate the performance of OmniGuide fibers and related stru ...

During a Phase I STTR Contract #F49620-03-C-0064 provided by AFOSR, Nukove Scientific Consulting addressed “Adaptive Laser Beam Control Using Return Photon Statistics” with considerable success. The Nukove/NMSU Team demonstrated the feasibility of combining Nukove’s statistical approaches to pointing estimation and target identification with a laboratory testbed at NMSU. This proposed Phase ...

An innovative system for geolocation of emitters in the field is proposed. The system integrates short baseline calibration methods with recent emitter location advances by Signatron Technology Corporation that combines TDOA, DF, and signal strength in directly optimized location estimate. The system requires significantly less data to be transmitted than conventional TDOA systems by using signa ...

To be effective, modern military command and control requires an enormous amount of communication, coordination, and collaboration among the various forces, services, and coalition partners involved. Many tools have been developed or adopted from industry to meet this need; however, these same tools have significant limitations, the most important being that none of the technologies are Òaware of ...

The Model-based Optimal System for Training (MOST) is an optimal Intelligent Team Tutoring System (ITTS) for training team and individual resource allocation skills. MOST will contain five models; (1) an optimal task performance model (expert model), (2) an optimal context model, (3) an optimal feedback model, (4) an optimal procedural training model, and (5) a student model. The optimal context, ...

Nova Engineering and UCSD propose a constant envelope orthogonal frequency division multiplexing (CE-OFDM) waveform as a software improvement to the current OFDM software defined radio (SDR) implementations. The proposed waveform allows the current WNW OFDM Signal-in-Space (SiS) to be inexpensively upgraded with a constant envelope operating mode. Constant envelope operation eliminates the probl ...

This STTR Phase II project continues the development of a new glass (designated MM-i) for ion-exchange glass waveguides and amplifiers used in l.55 um optical communication systems. There is excellent commercial potential for these glass materials and the waveguide lasers (lossless splitters) and optical amplifiers that may be fabricated from them. To date, development efforts in the communication ...
