Equation of state of liquid mercury to 520 K and 7 GPa from acoustic velocity measurements

Livia Eleonora Bove Kado

Ultrafast acoustics measurements on liquid mercury have been performed at high pressure and temperature in a diamond anvil cell using picosecond acoustic interferometry. We extract the density of mercury from adiabatic sound velocities using a numerical it ...

A Box Spline Calculus for the Discretization of Computed Tomography Reconstruction Problems

Michaël Unser, Masih Nilchian

B-splines are attractive basis functions for the continuous-domain representation of biomedical images and volumes. In this paper, we prove that the extended family of box splines are closed under the Radon transform and derive explicit formulae for their ...

Gas Sensing using Material and Structural Slow Light Systems

Luc Thévenaz, Sang Hoon Chin, Isabelle Dicaire

Slowing light is expected to enhance light-matter interaction, leading to more compact sensing devices. By simple tests we show that the reality is more complex and the only relevant quantity is the wave electric field. ...
