Physical Modeling of the Piano [PDF]
EURASIP Journal on Advances in Signal Processing, 2003 Over the past several years, this project has been aimed at constructing a physical model of the piano. The goal is to use Newton’s laws to describe the motion of the hammers, strings, soundboard, and surrounding air, and thereby calculate the sound produced by the instrument entirely from first principles.

A physical model for dementia [PDF]
Physica A: Statistical Mechanics and its Applications, 2017 Aging associated brain decline often result in some kind of dementia. Even when this is a complex brain disorder a physical model can be used in order to describe its general behavior. This model is based in first principles. A probabilistic model for the development of dementia is obtained and fitted to some experimental data obtained from the ...
