1. NIST SURFACE ROUGHNESS AND STEP HEIGHT CALIBRATIONS, Measurement Conditions and Sources of Uncertainty
Published: 3/18/2014
Authors: Theodore Vincent Vorburger, Thomas B Renegar, Xiaoyu A Zheng, Jun-Feng Song, Johannes A Soons, Richard M Silver
Abstract: NIST methods for calibration of surface roughness parameters and step height are described. The surface roughness parameters currently being measured include roughness average (Ra), root mean square (rms) roughness (Rq), average maximum height of the ...

2. Applications of Surface Metrology in Firearm Identification
Published: 1/8/2014
Authors: Xiaoyu A Zheng, Johannes A Soons, Theodore Vincent Vorburger, Jun-Feng Song, Thomas B Renegar, Robert Meryln Thompson
Abstract: Surface metrology is commonly used to characterize functional engineering surfaces. The technologies developed offer opportunities to improve forensic toolmark identification. Toolmarks are created when a tool comes into contact with a surface an ...

3. Applications of Surface Metrology in Toolmark Identification
Published: 1/8/2014
Authors: Xiaoyu A Zheng, Johannes A Soons, Theodore Vincent Vorburger, Jun-Feng Song, Thomas B Renegar, Robert Meryln Thompson
Abstract: Surface metrology is commonly used to characterize functional engineering surfaces. The technologies developed offer opportunities to improve forensic toolmark identification. In 2009, a report by the National Academies called into question, amon ...

4. Validation Tests for the Congruent Matching Cells (CMC) Method Using Cartridge Cases Fired With Consecutively Manufactured Pistol Slides
Published: 10/17/2013
Authors: Wei Chu, Mingsi Tong, Jun-Feng Song
Abstract: The National Institute of Standards and Technology (NIST) has developed the NIST Ballistics Identification System (NBIS) based on three-dimensional (3D) topography measurements on correlation cells [1]. The Congruent Matching Cells (CMC) method is u ...

5. Automatic Identification of Bullet Signatures Based on Consecutive Matching Striae (CMS) Criteria
Published: 9/10/2013
Authors: Wei Chu, Robert Meryln Thompson, Jun-Feng Song, Theodore Vincent Vorburger
Abstract: The consecutive matching striae (CMS) numeric criteria for firearm and toolmark identifications have been widely accepted by forensic examiners, although there have been questions concerning its observer subjectivity and limited statistical support. ...

6. The Effect of Tip Size in Calibration of Surface Roughness Specimens with Rectangular Profiles
Published: 9/2/2013
Authors: Jun-Feng Song, Thomas B Renegar, Johannes A Soons, Balasubramanian Muralikrishnan, John S Villarrubia, Xiaoyu A Zheng, Theodore Vincent Vorburger
Abstract: For the calibration of rectangular and trapezoidal profile roughness specimens, stylus tip will increase profile peak width and decrease valley width, which may cause the Ra changes (either increase or decrease, depends on the profile shape). Someti ...

7. Proposed ,NIST Ballistics Identification System (NBIS)Š Based on 3D Topography Measurements on Correlation Cells
Published: 5/17/2013
Author: Jun-Feng Song
Abstract: The invented ,NIST Ballistics Identification System (NBIS)Š using three-dimensional (3D) topography measurements on correlation cells can promote high accuracy and fast ballistics identifications [1]. The use of paired correlation cells can identify ...

8. Topography Measurements and Performance Comparisons between NIST SRM 2460 Standard Bullet Masters and BKA Bullet Replicas
Published: 7/31/2012
Authors: Jun-Feng Song, Theodore Vincent Vorburger, Robert Meryln Thompson, Susan M Ballou, Xiaoyu A Zheng, Thomas B Renegar, Richard M Silver
Abstract: Two Standard Reference Material (SRM) 2460 Bullets produced by the National Institute of Standards and Technology (NIST) were used as masters for the fabrication of replica bullets at the Bundeskriminalamt (BKA). The surface topography of the SRM ma ...

9. Development of Ballistics Identification ‹ From Image Comparison to Topography Measurement in Surface Metrology-
Published: 3/22/2012
Authors: Jun-Feng Song, Theodore Vincent Vorburger, Robert Meryln Thompson, Thomas B Renegar, Xiaoyu A Zheng, James H Yen, Richard M Silver, Wei Chu
Abstract: Fired bullets and ejected cartridge cases have unique ballistics signatures left by the firearm. By analyzing the ballistics signatures, forensic examiners can trace these bullets and cartridge cases to the firearm used in a crime scene. Current au ...

10. Stylus Tip-Size Effect on the Calibration of Periodic Roughness Specimens with Rectangular Profiles
Published: 3/21/2012
Authors: Thomas B Renegar, Johannes A Soons, Balasubramanian Muralikrishnan, John S Villarrubia, Xiaoyu A Zheng, Theodore Vincent Vorburger, Jun-Feng Song
Abstract: Stylus instruments are widely used for surface characterization. It is well known that the size and shape of the stylus tip affects the measured surface geometry and parameters. In most cases, increasing the tip size decreases the measured Ra value b ...
