Mathematical Exploration: Tennis Balls, Lines, and Geometric Transformations

Mathematics Teaching in the Middle School, 2010
Activities that use linear data as a model will help students understand linear functions. In this activity, students collect data and make connections to concepts used in geometry and measurement. Rather than teaching introductory algebra and geometry, this activity is intended to serve as a culminating task to reinforce material already learned.

Mathematical modeling of closed cycles of ball grinding

Soviet Mining Science, 1986
Principles of the mathematical description of the grinding process have been developed which make use of linear models of population balance and substitute for the real distribution of the time of grain processing inside the mill a combination of ideal extrusion and ideal mixing.

Mathematical modeling of predictive grinding for ball mill

2016 IEEE Region 10 Conference (TENCON), 2016
The aim of this work is to design a mathematical model for deriving acoustic signatures by analyzing the sound of a ball mill in its load varying conditions. The paper establishes an appropriate mathematical background that helps to predict dynamic breakage characteristics with respect to particle size distribution of different types of material ...
