A Shortfall in marine fisheries production is driving the development of aquaculture technologies on many fronts. Recirculating systems are regarded as critical components of many development schemes. However, interest and use of recirculating systems for production of marine organisms have lagged behind freshwater applications. A floating bead filter which is corrosion resistant (no metal parts), ...

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 ...

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 ...

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 ...

In the conduction of benchmark combustion experiments, a fuel spray nozzle that produces a steady-well-defined spray is needed. This fuel spray, of known properties, is a boundary condition for the atomization, mixing, and combustion which results throughout the combustor volume. Present spray nozzles use fluid turbulence, which is chaotic, to drive the spray formation. Because the turbulence ampl ...

Fire fighter burn injuries continue to be a frequent problem despite significant advances in protective clothing. A reason for this is the buildup of moisture in fire fighting garments as a result of sweating or fire fighting activities. This buildup of moisture increases the heat transfer through the garment and can result in scald burn injuries as the water is quickly heated. Currently, there is ...

Finish machining of structural ceramics can produce residual stresses, and subsurface defects (SSD) acting as stress concentrators, in the near-surface material. Residual stresses and SSD produced by machining affect the mechanical properties of ceramic components. In this context, it is essential that the residual stresses be properly quantified in ceramics, in order to establish suitable machini ...

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 ...

The storage photostimulable phosphor (SPP) technique has been demonstrated to be sensitive to ionization radiation. It is especially suited for detecting alpha particles since the efficiency is practically 100%. In addition to being able to quantify total ionization deposited in a SPP sensor, it also captures the radiation source distribution information in a digital image which can be readily ana ...
