Zeotrope refrigerant mixtures have been proposed and used for energy saving. Matching the temperature glide of the refrigerant to the temperature change of the heat sink and source, while simultaneously reducing the pressure difference seen by the compressor will result in significantly improved efficiency. A new cycle based on a mixture cascade combined with a rectifier column has recently been i ...

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 ...

New work is in progress on a CORBA interface standard for online interactive communication with DMIS-based Coordinate Measurement Machines (CMMs). This work is being pursued for submission to CAM-I via a recently organized object technology working committee of the North American DMIS Users Group. We will explore how to build upon this work for integration with existing manufacturing frameworks, e ...

THE UNCERTAINTY IN MEASURING NEUTRON DOSE EQUIVALENT RATES RESULTS IN UNCERTAINTY IN ASSIGNMENT OF THE PROPER DOSE TO OCCUPATIONAL RECORDS AND CAN RESULT IN IMPROPER IMPLEMENTATION OF CONTROLS TO LIMIT THE EXPOSURE. A NOVEL PORTABLE NEUTRON SPECTROMETER IS PROPOSED WHICH WILL REDUCE THE UNCERTAINTY OF SUCH MEASUREMENTS TO LESS THAN 20%. MANYCOMPONENTS OF THIS DEVICE ARE COMMERCIALLY AVAILABLE. SYS ...

TWO APPROACHES WILL BE EXAMINED TO SIGNIFICANTLY IMPROVE THESENSITIVITY OF LAUNDRY MONITORS TO DETECT AND SPECIFY LOCATION OF HOT PARTICLES ON LAUNDERED GARMENTS. THESE PROPOSED TECNIQUES HAVE HIGH POTENTIAL FOR DETECTING BOTH LOW ENERGY BETA AND ALPHA PARTICLE RADIATION AS WELL AS IMPROVING SENSITIVITY BY REDUCING BACKGROUND COUNT RATE.

This proposal describes a new research program to be established at the small business Still Sciences, LLC, in collaboration with Department of Physics of Oklahoma State University. The overall goal is to develop and commercialize an all-optical dosimetry system for industrial radiation processing based on a novel Pulsed Optically Stimulated Luminescence readout technique and a new Al2O3 material ...

We propose to characterize the early stage of consolidation of non-spherical powders to further the development of process models to enable simulation of powder metallurgy manufacturing for the consumer market, especially the automotive industry. Typically, spherical powders with a narrow size distribution are used for aerospace applications, while low-cost powders with irregular shapes and a wide ...

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 ...

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 ...
