Of more than 100 HF Radars operating within the Integrated Ocean Observing System (IOOS), more than half run either without recommended receive antenna pattern calibrations or with out-of-date calibrations, despite potential compromises to data quality. Cost is the primary inhibitor of frequent calibration, which generally requires a technician to drive a small vessel with mounted transponder in a ...

A need exists for advances in non toxic treatments for cover and barrier fabrics. Since polybrominated materials have been banned in many European countries and the production of a number of brominated additives terminated in the U.S. as well, future technologies must focus on non-halogenated treatments. In general, non-halogenated treatments (phosphates and borates) are not durable to aqueous sol ...

Concepts for in-situ measurement of moisture in the upper troposphere and lower stratosphere using Tunable Diode Laser Absorption Spectroscopy (TDLAS), a technology known to have potential in this application, will be developed. Known water vapor absorption bands in the wavelength range of available IR lasers (

The proposed effort is to design a space-qualified dual-frequency GPS/GLONASS receiver with enhanced capabilities for atmospheric remote sounding. While such soundings have been performed using GPS-only receivers, a space-based GPS/GLONASS receiver would be superior in terms of coverage and integrity cross- checking, as well as the ability to process the unencrypted GLONASS L2 signal. This design ...

Two-dimensional measurement machines, such as microlithography and computed tomography systems, are subject to distortions in the measurement field due to imperfections in their hardware and software. Certified methods to characterize and quantify such distortions are urgently needed. An innovative self- calibrating scheme is tendered which eliminates the disadvantages of previous self-calibration ...

Arca proposes research leading to development of a suite of methodology support products to help meet the need for innovative assurance techniques appropriate for emerging information technologies. The product will consist of a licensable methodology and supporting materials for specifying, building, and evaluating assurance arguments for products and systems based on the capability of security en ...

American health care is in the midst of momentous change. Quality improvement principles are being used increasingly to enhance productivity and efficiency of health care delivery and to help contain costs. In producing patient outcomes and resource utilization measures, it is vital to control appropriately for case mix (i.e., differences in patients due, e.g., to illness severity) in the predicti ...

We will develop technology, termed a Ruggedized Wind Measurement System (RWMS), to measure directly extreme winds with high space and time resolution, focusing on the winds that occur beneath hurricanes at land fall. This development effort will include design, fabrication of two prototype RWMS units, and a series of proof-of-concept demonstrations in strong mountain-induced downslope and severe t ...

Precision underwater mapping is an important requirement of projects ranging from wreck surveys and environmental impact studies to mine clearing operations and marine science projects. Small Autonomous Underwater Vehicles (AUV) are capable platforms for mapping operations as they are easily deployed and can operate in hazardous environments. We propose the development of an Automated Imaging and ...

This project will complete the design and fabrication of a novel high-resolution termal microprobe, and evaluate its potential for measuring the temperature of operating microelectronic components with a temperature resolution of 0.01 C and a spatial resolution of 10 nm. Fabrication is in two major steps: formation of a prototype AFM microprobe, and the addition of a thermocouple junction to the ...
