3D Printing technologies have been around for the better part of 30 years now, and researchers today have a reasonably good understanding of how the different processes work. A focus for the next era of 3D printing will likely be to gain a deeper... READ MORE
Traditional photoplethysmography (PPG) - the extraction of cardiovascular information through its modulation of light intensity- requires a device to be attached to the patient. Video PPG (vPPG) seeks to remove this requirement by observing the variations in the skin tone measurements by a webcam. While... READ MORE
This work provides a detailed theoretical and numerical study of the inverse problem of identifying flexural rigidity in Kirchhoff plate models. From a mathematical standpoint, this inverse problem requires estimating a variable coefficient in a fourth-order boundary value problem.This inverse problem and related estimation problems...

We have undertaken an ambitious program to visually classify all galaxies in the five CANDELS fields down to H 70% across the full magnitude range) and depends on both the galaxy magnitude and the galaxy type, with disks showing the highest level of agreement (>50%)... READ MORE
Impact of Upgrading Equipment for Strength of Materials Labs on Student Perceptions, Motivation, and LearningAbstractAn important component of teaching introductory Strength of Materials (Mechanics ofMaterials) concepts to undergraduate engineering and technology students is the inclusion oflaboratory experiments, which give the students the opportunity to...

The objective of this short note is to employ an equation error approach to identify a variable parameter in fourth-order partial differential equations. Existence and convergence results are given for the optimization problem emerging from the equation error formulation. Finite element based numerical experiments show... READ MORE
