Description of original award (Fiscal Year 2013, $278,014)
| This 2014 modification provides additional funding to expand the work of developing a research database of bullet and cartridge case toolmark data, consisting of traditional reflectance microscopy images and three-dimensional surface topography. NIST will build on this initial effort and work to improve the relevancy and utility of the database. Under this modification, NIST will perform the following additional work: (1) Collection of at least 500 additional test fire specimens, including specimens from studies involving persistence firings and consecutively manufactured gun components; (2) Measurement and pairwise correlation of the surface topography of the additional specimens (breech face, firing pin, and land impressions); (3) Design, development, testing, and deployment of a searchable web database that provides public access to bullet and cartridge case measurement data acquired by NIST and enables users to share their own data; (4) Population of the web database with the topography measurement data acquired by NIST during the project; and (5) Dissemination of results. NIST will further expand the original project by providing the following additional deliverable items: (1) A minimum of 500 additional test fire specimens; (2a) Optical intensity images and three-dimensional topography data of the additional test fire specimens; (2b) Pairwise similarity values for the topography of the additional test fire specimens; (3) Searchable web database hosted by NIST that provides public access to bullet and cartridge case measurement data acquired by NIST during the project and enables users to share their own data sets; and (4) Conference presentation and journal paper describing the project and results obtained. |
