Dynamic scaling of QENS spectra of glassy water in aging cement paste

Physica A: Statistical Mechanics and its Applications, 2002
Abstract We propose a new method for the analysis of high-resolution incoherent quasi-elastic neutron scattering spectra of water in porous media and apply it, in particular, to a case of water in hydrated tricalcium silicate. We plot the normalized frequency-dependent susceptibility as a function of a scaling variable ω/ωp, where ωp is the peak ...

QENS-an enhanced version of the electric network simulator program

Conference Record of the 1988 IEEE Industry Applications Society Annual Meeting, 1991
A commercially available AC/DC load flow program geared specifically to transit systems has been enhanced to simulate the peculiarities of the Vancouver Advanced Light Rapid Transit system. The converter model has been revised to simulate accurately a 12-pulse parallel-connected converter station with inversion capability.

The use of Fourier transforms in the analysis of QENS data

Physica B: Condensed Matter, 1996
Abstract The traditional method of analysing QENS data has been to fit a model function to the S ( Q , ω ) taking into account the shape of the resolution function. The drawback of this method is the reliance on a model for S ( Q , ω ), for example, one (or more) Lorentzians.

Molecular Dynamics in Nematic Phases: QENS and NMR Spectroscopy

1992
Molecular dynamics in liquid crystals (particularly smectic and to a lesser extent nematic phases) has been extensively studied by quasi elastic neutron scattering (QENS)1-11 as well as by magnetic relaxation12–17. Nevertheless, these two different techniques have never been combined, probably due to the fact that, quite often, the results obtained did
