Excavator 3D pose estimation from point cloud with self‐supervised deep learning

Computer-Aided Civil and Infrastructure Engineering, EarlyView.
Abstract Pose estimation of excavators is a fundamental yet challenging task with significant implications for intelligent construction. Traditional methods based on cameras or sensors are often limited by their ability to perceive spatial structures. To address this, 3D light detection and ranging has emerged as a promising paradigm for excavator pose

Linking the Ultraviolet Index to the “shadow rule” for sun protection: A theoretical model applied with a southern hemisphere example

Photochemistry and Photobiology, EarlyView.
We demonstrate the potential utility of the shadow rule and how it may be understood in relation to the UV Index. The shadow rule indirectly determines the sun's altitude by observing the length of a person's shadow during the course of the day. When the shadow cast by the sun on a horizontal surface is shorter than the height of the person casting the

Image of mathematics: A case study of two women's early mathematics experiences

School Science and Mathematics, EarlyView.
Abstract People often view mathematics as abstract, cold, and irrelevant to real life, and their school experiences likely influence such views. In this case study, we investigated the mathematics experiences of two women who participated in an afterschool girls‐only STEM club 30 years ago when they were in fifth and sixth grades.

The Impacts of Problem‐Posing Intervention on the Mathematical Proficiency of Undergraduate Developmental Mathematics Students' Developmental Mathematics

School Science and Mathematics, EarlyView.
ABSTRACT This study investigates the impact of problem‐posing on the mathematical proficiency and engagement of 56 Developmental Mathematics (DM) students enrolled in a noncredit college mathematics course. Using a quasi‐experimental design, one of two existing classes was selected as the experimental group and received a 5‐week intervention focused on

Function Art: Linking Mathematics, Technology, and Visual Arts

School Science and Mathematics, EarlyView.
ABSTRACT This study investigated students' understanding of mathematical functions and strategies to create artwork using GeoGebra. It was framed by the principles of constructionism and examined how students use functions in creating artworks. We gathered data from students' artworks using the Algebra view and the Construction Protocol in the GeoGebra
