Robust Inverse Parameter Fitting Of Thermal Properties From The Laser-Based Angstrom Method In The Presence Of Measurement Noise Using Physics-Informed Neural Networks (Pinns), Shanmukhi Sripada, Aalok U. Gaitonde, Justin A. Weibel, Amy M. Marconnet Jan 2024

Robust Inverse Parameter Fitting Of Thermal Properties From The Laser-Based Angstrom Method In The Presence Of Measurement Noise Using Physics-Informed Neural Networks (Pinns), Shanmukhi Sripada, Aalok U. Gaitonde, Justin A. Weibel, Amy M. Marconnet

CTRC Research Publications

The two-dimensional laser-based Ångstrom method measures the in-plane thermal properties for anisotropic film-like materials. It involves periodic laser heating at the center of a suspended film sample and records its transient thermal response by infrared imaging. These spatiotemporal temperature data must be analyzed to extract the unknown thermal conductivity values in the orthotropic directions, an inverse parameter fitting problem. Previous demonstration of the metrology technique used a least-squares fitting method that relies on numerical differentiation to evaluate the second-order partial derivatives in the differential equation describing transient conduction in the physical system. This fitting approach is susceptible to measurement noise, …

Popular Stem Related Career Choices For Middle School Students, Damilola B. Ayokanmi, Paul Asunda Jan 2024

Popular Stem Related Career Choices For Middle School Students, Damilola B. Ayokanmi, Paul Asunda

Indiana STEM Education Conference

In order to build and sustain student interest in STEM disciplines, it is important to first ascertain the existing trends in their career choices including factors influencing them. Middle school is a pivotal time for both boys and girls as they start forming identities and career choices and can begin to select both elective courses and extra-curricular activities, based on interests (Webb & Rosson, 2013), and yet, these early years are given low priority in integrated STEM education discussions. This study was guided by the following research question, “What are the popular career choices selected by middle school students …
