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 numerous management tools currently employed for disaster response presents a barrier when attempting to share information across boundaries. This impediment is due to the different reporting formats, data storages, or incompatibility of software being deployed. Geocent proposes implementing multiple GIS open standards serves as the backbone for exchanging critical information to facilitate in ...

Special Operations forces (SOF) operate in all weather conditions. It has identified a need for a micro-cooling system that can be vehicle mounted and man-portable, as well as provide a capability to cool vehicle mounted communications and electronics equipment. To meet the needs of SOF the system must be small, lightweight, quiet, low power, and gasless. We propose a compact micro-cooling system ...

This Phase I SBIR research effort involves a feasibility study and an in-depth investigation into technologies that would be applied in ship compartment inspection to ensure full space accountability. A trade study will identify the most promising technology to develop and design a handheld, man-portable See-Thru-Eye capable of penetrating a host of barriers of different thicknesses and constructi ...

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 ...
