Carey, Jason P., Melenka, Garrett W., Nobes, David S., Major, Paul W.
Archwire rotation is used in orthodontic treatment to alter the labiolingual orientation of a tooth. Measurement of the 3-dimensional (3D) motion of the orthodontic brackets requires a new configuration of the orthodontic torque simulator. The orthodontic torque simulator was coupled with a...

Vision-based Impedance Control of a 7-DOF Robotic Manipulator for Pick-and-Place Tasks in Grasping Fruits
Download2022-06-01
Chen, Qiguang, Wan, Lucas, Ravichadran, Prabahar, Pan, Ya-Jun, Chang, Young Ki
A vision-based impedance control method is applied to a 7-degree-of-freedom (7-DOF) Franka Emika (FE) Panda robotic manipulator to complete pick-and-place tasks with human-like grasping of fruits. The interfaces between different hardware and the controller are developed using robotic operating...

Dynamic Fragmentation of Planetary Materials: Length Scale Quantification and Semi-Analytical Modelling
Download2013
Rogers, Robert, Spray, John, Hogan, James
The dynamic fragmentation of planetary materials during impact into finite targets has been examined. A particle tracking algorithm was implemented to estimate the size and velocity of fragments ejected from the rear of the target. A total of 76 experiments were performed for four material,...

Impact Deposition Behavior of Al/B4C Cold-Sprayed Composite Coatings: Understanding the Role of Porosity on Particle Retention
Download2023-03-22
Farid, Hannaneh Manafi, McDonald, André, Hogan, James David
This study explores the role of porosity in the impact deposition of a ceramic-reinforced metal-matrix (i.e., Al/B4 C) composite coating fabricated via cold spraying. The Johnson–Holmquist–Beissel constitutive law and the modified Gurson–Tvergaard–Needleman model were used to describe the high...

Integration Of Artificial Neural Network And Finite Element Method For Prediction Of Elastic-Plastic Deformation Behaviour Near Crack Tips
Download2022-06-01
It has been widely accepted that stress and strain fields near the crack tip govern crack propagation behavior. In most cases, an elasto-plastic analysis is required to determine local stress and strain fields around the crack tip due to the high stress concentration. However, complexities of...

Sanford, Paul W., Carretero, Juan A.
The forward and inverse displacement problems (FDP, IDP) are solved for a 4-DOF hybrid cable-driven parallel manipulator. This manipulator uses three cables and one extensible rod to manipulate the mobile platform, and shares some kinematic similarities to the well-studied Stewart-Gough...

Orthodontic bracket manufacturing tolerances and dimensional differences between select self-ligating brackets
Download2010
Nobes, David S., Carey, Jason P., Major, Paul W., Major, Thomas W.
In all manufacturing processes there are tolerances; however, orthodontic bracket manufacturers seldom state the slot dimensional tolerances. This experiment develops a novel method of analyzing slot profile dimensions using photographs of the slot. Five points are selected along each wall, and...

Investigation into the effects of stainless steel ligature ties on the mechanical characteristics of conventional and self-ligated brackets subjected to torque
Download2014
Heo, Giseon, Nobes, David S., Al Fakir, Hussam, Major, Paul W., Melenka, Garrett W., Carey, Jason P.
Objective: Torque is applied to orthodontic brackets in order to alter the buccal-lingual angulation of a tooth. One factor that can affect torque is the ligation mode used to retain the archwire in the bracket slot. The objective of this study was to investigate the effects of stainless steel...
