Improvement of Fourier Polarimetry for applications in tomographic photoelasticity [PDF]

open access: yes, 2006
The use of the Fourier Polarimetry method has been demonstrated to extract the three characteristic parameters in integrated photoelasticity. In contrast to the phase-stepping method, it has been shown that the Fourier method is more accurate.

Moments of inertia for solids of revolution and variational methods [PDF]

open access: yesEuropean Journal of Physics, 2006
We present some formulae for the moments of inertia of homogeneous solids of revolution in terms of the functions that generate the solids. The development of these expressions exploits the cylindrical symmetry of these objects, and avoids the explicit use of multiple integration, providing an easy and pedagogical approach.
