Cavity Ring-Down (CRD) spectroscopy is developing into a precise tool for measuring gaseous contaminants in ultrahigh vacuum and other environments. Optimum sensitivity is obtained by driving the CRD spectrometer in the mid-IR part of the spectrum with about 100 mWatts of average power at 5 kHz and with pulse lengths of 10-50 nsec. Bandwidths of 100 MHz are required. There are no commercial lasers ...

Reuse in software engineering is an exciting concept that has yet to be reliably implemented. The number of program subroutines that are truly generic (and therefore applicable across all applications) is limited. However, there are specific applications that are required by many organizations, albeit with a set of constraints specific to each organization. This project proposes to design a too ...

THE IMPACT OF INDUSTRIALIZATION IN COASTAL REGIONS AND THE DEGRADATION OF ENVIRONMENTAL CONDITIONS IN THE VICINITY OF SEAFOOD PRODUCING REGIONS HAS BECOME EVIDENT FROM THE QUALITY OF FOODS PRODUCED IN THESE REGIONS. AFFINITY PURIFIED POLYCLONAL ANTIBODIES ARE BEING DEVELOPED TO PROVIDE A RAPID METHOD FOR THE EVALUATION OF LISTERIA MONO- CYTOGENES AND TOXINS FROM VIBRIO CHOLERAE IMPLICATED IN FOODP ...

The overall quality and the comprehensive strength, in particular, of concrete are critically dependent on the water content in the concrete mixture. It is also essential to know if the concrete has reached a stage of moisture equilibrium before surface finishes such as paint or carpet can be applied. At present, no reliable method or easy-to-use instrument exists for determining the moisture co ...

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 ...

There is a need for accurate and cost effective airborne techniques to estimate fish biomass in the open ocean. Arete proposes to develop in Phase I optimal detection algorithms using existing imaging LIDAR data collected with the Fisheye(R) sensor. These algorithms will be developed to allow real-time detection of fish and fish schools, discrimination between fish and ambient clutter, and discr ...

In response to the increasing demand for better understanding of the manufacturing processes and the machining systems, a new testing standard--ASME B5.54 and a family of new testing instruments have been developed for evaluating the performances of a variety of CNC machining centers. Because of the advancement and versatility of the new instruments, test data are being collected at a much higher ...

This proposal addresses development of CAD software for simulating non-linear optical materials. The software will provide a virtual lab in which experimental setups are simulated. The proposed software is based on the use of a Maxwell differential equation solver, the Finite Difference Time Domain (FDTD) method. This numerical method has been developed by numerous researchers since 1968 and no ...

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 ...
