Lattice Boltzmann Modeling From the Macro- to the Microscale - An Approximation to the Porous Media in Fuel Cells -

Fuel cell (FC) is a device that gives us electrical and thermal energy from the chemical energy present in the fuels involved during the conversion process. The chemical conversion process occurs thanks to the different constitutive layers in the FC, i.e., active layer, anode/cathode support layer, catalyst layer, gas diffusion later and electrolyte. Most of them have the characteristic to allow t

Tone restricts F0 range and variation in Kammu

The aim of this study is to investigate whether the occurrence of lexical tones in a language imposes restrictions on its pitch range. We use data from Kammu, a Mon-Khmer language spoken in Northern Laos, which has one dialect with, and one without, lexical tones. The main finding is that speakers of the tonal dialect have a narrower pitch range, and also a smaller variation in pitch range.
