The objective of Phase II is to continue our efforts from the Phase I project and perform in-depth testing of technologies critical to achieving the required level of measurement performance. The Phase II project will involve the design of the NOAA water vapor profiling lidar and testing of component parts, seeking external sources of funding for the systems (for Phase III) and further creating a ...

The recent emergence of the Silicon Drift detector (SDD), for use in energy dispersive x-ray spectrometry (EDS), has made possible x-ray event streams with count rates as high as 1-10 Mcps. A problem with existing digital signal processing, as applied to SDDs, is the significant presence of coincidence peaks above the x-ray background. These coincidence peaks occur with amplitudes comparable to lo ...

The vertical water vapor profile into the atmosphere is measured around the world using balloon-borne radiosondes that take measurements twice a day when the balloons are launched. The objective of this proposal is to establish the feasibility of measuring the amount of water vapor vertically, in the atmosphere as a function of altitude using a Light Detection and Ranging (lidar) operating in the ...

The recent emergence of the Silicon Drift detector (SDD), for use in Energy Dispersive x-ray Spectroscopy (EDS), has made possible x-ray event streams with input count rates in the range of 1-10 Mcps. Modern digital pulse processors are therefore required to run at fast time constants to achieve reasonable throughput; however, this causes significant coincidence artifacts to appear in the spectrum ...

Under this proposal, Virtual Global, Inc. proposes to work with NIST to develop RBAC-BASED WORKFLOW, a workflow system that will use RBAC in a web services model as a form of middleware that can be "packaged" accessed, configured, and reused by integrating with existing trusted RBAC implementations.

There is a need for a simple, affordable method for measuring domoic acid in the field. This project will develop a rapid, onsite kit for domoic acid featuring a filter membrane that produces a readable color response without need for instrumentation. The filter membrane contains three or more zones with different assay characteristics in close proximity. These zones will indicate different co ...

The Phase 2 objective is to provide NIST with a modular gauge head unit equipped with InsituTec's standing wave probe technology. The complete gauge head unit will be retrofitted to the NIST M48 which is one of the most precise measuring machines in the world. This unit will enable NIST to achieve the agency's program goal in dimensional metrology which is to provide microscale measurement capacit ...

We propose Ranger ES, a low cost, autonomous underwater vehicle (AUV) for three-dimensional profiling and water samplings of chemical, physical, and biological parameters of oceanic and fresh waters. The AUV will be programmable by point and click to analyze a volume of water continuously for the selected parameters. After returning for pickup after a day¿s run, it will download its data into a ...

The pressing need exists within industry to accurately measure high aspect ratio microscale structures. For example, diesel injector nozzles are manufactured with microscale holes ranging from 50-200 micrometers in diameter and 3-5 mm depths. One fundamental challenge is to nondestrucvely measure these features in order to validate models, enhance manufacturing processes, and reduce fuel emissions ...

A smart machine tool must be able to monitor its condition and report problems. Every CNC machine should provide an alarm for tool condition problems, including tool wear, much as every automobile has a low oil indicator. Tool wear is particularly important for unattended machining as a worn tool can ruin a part. All current tool condition systems operate "blind" without direct information on curr ...
