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 ...

CNC machine tools continue to be a critical part of manufacturing; yet, a majority of the users still do not have a comprehension of how the systems function internal to the control system. With the current capability and cost benefits of personal computers and multimedia tools, the opportunity to create an educational tool to display the inner workings of the CNC system is feasible. This proposal ...

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 ...

Dia-Tool proposes herein a new manufacturing machine that will combine the processing steps of shaping the indenter and the measurement of the resulting cone into a single automated Diamond Indenter Finishing Machine. The images of the edges of the indenter cone are digitized through an imaging array and directly stored in computer memory. The indenter cone images are then transformed by image ana ...

The program objective is to investigate the feasibility of using a very high frequency (VHF) [70 MHz] plasma technique to produce high efficiency a-SiGe:H solar cells at relatively high deposition rates. Using the VHF technique, high quality a-SiGe:H material is expected due to enhanced low energy ion bombardment of the growing film surface which has been found to be beneficial to the growth of th ...

The near-field scanning optical microscope can supply information on the shape and electrical properties of surfaces with nanometer resolution. The quantitative interpretation of images is difficult because of the difficulty of electromagnetic field solutions in the near-field limit. We propose to supply software to aid in this analysis. The finite-element programs generate two and three-dimension ...
