The X-ray intensity as measured by detectors depends on all aspects of the imaging system ranging from the source spectrum to various scatter events during the photon transport. The proposed simulator models the entire X-ray detection process from photon generation to various scatter events to the eventual detection of transmitted/scattered photons. In particular, the simulator models the two impo ...

The proposed goal of Nevada Nanotech Systems Inc for the Phase II program is to adapt a commercially available gas chromatograph-mass spectrometer instrument for the problem of detecting U.S. currency via unique vapor signature in confined spaces and then field test three prototype units, operated by government personnel, during a 6-month field test. After this test, we will provide detailed docu ...

For Phase II work, we propose to complete the development of the DICOS compliant ATR algorithm whose feasibility has been demonstrated by results of Phase I work. Important project milestones for the first base year of Phase II are as follows: (1) implementation of the DICOS standard including network protocol, (2) improvement of the proposed ATR algorithm in terms of explosive detection performan ...

The proposed goal of Nevada Nanotech Systems Inc for the Phase I program is to select a practical technological solution and develop a Con-Ops for the problem of detecting U.S. currency via unique vapor signature(s) in confined spaces for three related, though unique, application scenarios (bags, vehicles, and shipping containers). Nevada Nano will document a matrix of technical and operational re ...

This Phase I proposal describes the development of an Automatic Threat Recognition (ATR) algorithm for volumetric CT data. Our ATR algorithm consists of four stages: (1) preprocessing of CT data, (2) object segmentation of preprocessed CT data, (3) post-processing of segmentation results, and (4) explosive detection from the segmented objects. The ATR algorithm will be made computationally efficie ...

This Phase I proposal describes (1) an automated image quality assessment (IQA) software to objectively quantify image quality of airport security X-ray imaging systems for both checked and carry-on baggage and (2) a design for a novel test phantom specialized for security CT scanners. For fixed images, automated algorithms will measure the Modulation Transfer Function (MTF) and Contrast-to-Noise ...

The worldwide ocean going freight transportation infrastructure, known as the Marine Transportation System (¿MTS¿) is the cornerstone of the global economic well-being. Approximately ninety percent of all cargo moves via the MTS. However, one need only look to the open movement of containerized cargo to find simple, effective, and efficient means of large-scale economic damage. The result is a c ...

We propose to develop an integrated Cryptography Module (CM) and RTU (CMRTU) for SCADA applications. When used in CM mode, our CMRTU will be easily retrofitted into existing SCADA networks. When used in advanced RTU mode (where higher bandwidth connections are available), our CMRTU will provide both a secure gateway function and secure Internet protocols for interaction with either central monitor ...
