The Effect of Water Layer Covering Substrate Surface on the Deformation of the Impacting Particle Deposited by Liquid Cold Spray
Download2022-06-01
Khamsepour, Peyman, Akbarnozari, Ali, Garmeh, Saeed, Moreau, Christian, Dolatabadi, Ali
Cold spray is a deposition method developed for manufacturing metallic coatings by impacting high-velocity metallic powders on a substrate surface at around room temperature. Because of the low temperature of impacted particles, no oxidation or phase transformations occur during spraying....

Eye-In-Hand/Eye-To-Hand Cooperated Peg-In-Hole Microassembly Operations Using Coordinate-Based Augmented Reality
Download2022-06-01
A new eye-in-hand/eye-to-hand cooperated visual system in peg-in-hole microassembly work is assisted by coordinate-based augmented reality (AR) through three dimensional (3D)-hybrid visual calibration and servo. The 3D hybrid visual calibration is to combine real camera’s intrinsic parameters...

Developing a Dynamic Model of the Standard Neonatal Patient Transport System using Lagrange’s Equation in the Pitch Plane
Download2022-06-01
Gibb, K., Kehoe, P., Hurley, J., Aubertin, C., Greenwood, K., Ibey, A., Redpath, S., Chan, A.D.C., Green, J.R., Langlois, R.G.
During transport to critical care centres, neonatal patients can be exposed to elevated levels of vibration which may pose a risk to the patients’ health. In Ontario, a standardized Neonatal Patient Transport System (NPTS) has been implemented in ground and air ambulances, and studies to...

Investigating mechanisms of laser pulse-induced reflectivity modulations in photoacoustic remote sensing with a 10 million frames-per-second camera
Download2023-03-07
Haven, Nathaniel J. M., Martell, Matthew T., Li, Haoyang, Hogan, James D., Zemp, Roger J.
Photoacoustic remote sensing has been recently developed as an all-optical imaging modality capable of imaging a variety of endogenous contrast agents label-free. Initially predicted laser pulse-induced refractive index perturbation-based interrogation beam reflectivity modulations have been...

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...
