Lead in household paint and dust is a serious health hazard, as low-level lead exposure can result in a number of adverse health effects, especially in children. Onsite and real-time detection and quantification of lead in paint/dust are very important to homeowners and certified lead-based paint removal professionals. Toward this end, both field-portable equipment (such as X-ray fluorescenc ...

identified needs for the thermal control and ESD functions of the Prometheus Program's hardware for the heat rejection system for the planned nuclear system. These efforts can also serve uniquely the (CEV) radiator systems needs. The TCMS for the radiators of the both CEV and Prometheus missions need to operate at higher temperatures and provide the space environment stable low ratio of (αs/εT) ...

In Topic X1.03 NASA (JPL) is seeking to extend and implement long distance exploratory surface rover missions to gain knowledge of surface topology and roughness. The benefit is to identify suitable sites for future landings of human or robotic missions and to aid in pinpoint landings. High resolution millimeter wave radar sensors provide a low cost, reliable way for a Moon or Mars Rover to dete ...

In this SBIR Phase I project, Vega Wave Systems, Inc. will develop and demonstrate a novel InGaP-GaAs heterojunction bipolar transistor power amplifier for long-range X-band communications. The Phase I objective is to design and fabricate a new type of heterojunction bipolar transistor in order to achieve high device performance for power amplifiers (PAs). In addition, monolithic power combiners ...

NASA's vision of Space Exploration will require advancements in communication systems to maintain flexibility and adaptability to changing needs and requirements. The research outlined in this project will develop a hardware/software design environment that will allow NASA engineers to automatically develop flexible, reconfigurable communications systems. We will develop automated compiler algor ...

This Phase I research proposal is aimed at demonstrating the feasibility of an innovative architecture comprising control augmentation and on-line health monitoring system. This architecture integrats Flush Air Data System (FADS) with Reconfigurable Generalized Predictive Control (RGPC) technologies. The Phase 1 effort includes identification and description of all supporting modules, their funct ...

SUBSTANTIALLY SHORTENED TIME TO GERMINATE SEEDS, IMPROVED RATE OF GROWTH OF YOUNG PLANTS, MORE MASSIVE AND RAPID ROOT GROWTH WITH RESULTANT GREATER DRY WEIGHT IS ACHIEVED BY SUBJECTING SEEDS AND PLANT SPECIMENS TO FREQUENT CHANGES IN ATMOSPHERIC PRESSURE. THESE PRESSURE CHANGES ARE WITHIN THERANGE OF ATMOSPHERIC BAROMETRIC VARIATIONS. ENVIRONMENTAL CHAMBERS OF RELATIVELY SIMPLE CONSTRUCTION WITH A ...

WE PROPOSE TO BUILD A SOFTWARE PACKAGE FOR SOLVING GENERAL LARGE SYSTEMS OF NONLINEAR EQUATIONS SUCH AS THOSE ARISING FROM NONLINEAR PARTIAL DIFFERENTIAL EQUATIONS. PHASE I WILL FOCUS ON TESTING A RANGE OF METHODS BASED ON EFFICIENT VARIANTS OF NEWTON'S METHOD AND PRECONDITIONED CONJUGATE GRADIENT TYPE TECHNIQUES AS WELL AS ON A CLASS OF JACOBIAN-FREE ITERATIVE METHODS. THESE METHODS HAVE ATTRACTE ...
