The work proposed will provide a demonstration of feasibility and specific design recommendations for building an elevated-temperature resonating crystal balance with nanogram sensitivity. The approach will build upon existing technology commercialized by Masscal for operating a QCM in a temperature-controlled calorimeter. Precise temperature control and new types of crystal sensors will be used t ...

A novel chemical vapor deposition (CVD) based step-flow epitaxy process is proposed for controllable growth of SiC nanowires with high polytype integrity. SiC nanowires will be grown in a modified commercial high-temperature CVD reactor, used by industry for growing high-quality SiC epitaxial thin films. Different polytypes of SiC nanowires will be grown by choosing appropriate substrate materials ...

This proposal introduces the Detecting Intrusion from Network Anomalies (DINA) system, which uses data mining tools to automatically detect anomalous behaviors that can be related to undesired intrusion and/or attacks upon computer networks, as well as other use patterns which may indicate behaviors which are non-hostile but still problematic. The application will make use of Ensembles of Decision ...

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 ...

Most commercial filters have significant loss even in the passband of the filter. This problem is further exacerbated when the filter must be integrated or inserted within an optical fiber. Translume has developed over the last few years means and expertise to micromachine single-mode fiber using a combination of femtosecond laser pulses and highly anisotropic hydrofluoric acid etching. We propose ...

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.
