Schofield, Jonathon S., Dawson, Michael R., Melenka, Garrett W., Carey, Jason P.
Purpose: This paper evaluates the material properties and dimensional accuracy of a MakerBot Replicator II desktop 3D printer. Design Methodology: A design of experiments (DOE) test protocol was applied to determine the effect of the following variables on the material properties of 3D printed...

Automated Microscopy and Particle Size Analysis of Dynamic Fragmentation of Natural Ceramics
Download2013
Castillo, Josemar, Rogers, Robert J., Rawle, Alan, Spray, John, Hogan, James
The dynamic fragmentation of gabbro and granitoid tiles, and coarser and finer grained granitoid blocks have been examined for impact energies of 21–6180 J. Intra-grain fragmentation and inter-granular frictional melting were observed to be common features of the fragmentation process....

A tubular braided composite bone cast for improving the efficiency and quality of bone fracture treatment is investigated. Finite element analysis was used to evaluate stress concentrations in fracture sites supported with plate and tubular casts. The stress in a plated bone is 768 % of that in a...

Multi-Objective Optimization Framework for Landmark Measurement Error Correction in Three Dimensional Cephalometric Tomography
Download2013
Lagravère, Manuel O., Carey, Jason P., DeCesare, Alessandro, Secanell, Marc
The purpose of this study is to minimize errors that occur when using a four vs six landmark superimpositioning method in the cranial base to define the co-ordinate system. Cone beam CT volumetric data from ten patients were used for this study. Co-ordinate system transformations were performed....

Dynamic Fragmentation of Planetary Materials: Sub-Hypervelocity Ejecta Measurements and Velocity Scaling during Impact Testing
Download2013-01-01
Hogan, James, Vincent, Gregory, Spray, John, Rogers, Robert, Schneider, Markus
Ejecta velocity measurements were made during impacts into solid planetary materials. Ejecta velocity fields overlie each other when normalized by vmax, v50%mass, and v50%KE; these correspond to the maximum velocity and median values of mass and kinetic energy among ejecta velocities....

Braces are used by orthodontists to correct the misalignment of teeth in the mouth. Archwire rotation is a particular procedure used to correct tooth inclination. Wire rotation can result in deformation to the orthodontic brackets, and an orthodontic torque simulator has been designed to examine...

Constructing set-valued fundamental diagrams from jamiton solutions in second order traffic models.
Download2013-01-01
Flynn, M.R., Rosales, R.R., Kasimov, A. R., Seibold, B.
Fundamental diagrams of vehicular traffic flow are generally multi-valued in the congested flow regime. We show that such set-valued fundamental diagrams can be constructed systematically from simple second order macroscopic traffic models, such as the classical Payne-Whitham model or the...

The Effect on Elastic Modulus of Rigid-Matrix Tubular Composite Braid Radius and Braid Angle Change Under Tensile Loading
Download2013
Melenka, Garrett W., Leung, Cheequn K., Nobes, David S., Carey, Jason P.
The objective of this paper is to assess changes in braid radius and braid angle of braided composite tubes under tensile loading using stereomicroscope digital image correlation (DIC) based optical measurement techniques. Using this approach, displacement fields were calculated and three...

Adeeb, Samer, El-Rich, Marwan, Lewicke, Justin, Carey, Jason P., Schofield, Jonathon, Parent, Eric
Sit-to-stand transfer (STS) is a common yet critical prerequisite for many daily tasks. Literature conducted on healthy STS often assume the body to behave symmetrically across the left and right side; yet only a few studies have been conducted to investigate this supposition. These studies have...
