Abstract: This paper studies how the GeoGebra 3D Calculator with augmented reality (AR) serves as a tool for visualizing 3D graphs from functions of two variables in a mid-sized multivariable calculus ...

Imagine that you want to know the most efficient way to make a torus—a doughnut-shaped mathematical object—from origami paper. But this torus, which is a surface, looks drastically different than the ...

Inspired by the shape-shifting skin of octopuses, Penn State researchers developed a smart hydrogel that can change appearance, texture, and shape on command. The material is programmed using a ...

Abstract: The accurate segmentation of brain tumor is significant in clinical practice. Convolutional Neural Network (CNN)-based methods have made great progress in brain tumor segmentation due to ...
