Analysis of Non-Gaussian Parameter on Metallic Glass-Forming Cu-Ti-Zr Melts
To explore the mechanism behind slow dynamics of the glass transition is an interesting topic from a statistical physical point of view [1, 2]. One of characteristic dynamical properties in glass-forming systems is described by a non-Gaussian parameter α2(t) [3], which is related to the mean-square and –fourth displacements, M2(t) and M4(t), through the relation α2(t)=3M4(t)/5M2(t)-1. It has a ...
متن کاملAnalysis of Non-Gaussian Nature of Network Traffic
To study mechanisms that cause the nonGaussian nature of network traffic, we analyzed IP flow statistics. For greedy flows in particular, we investigated the hop counts between source and destination nodes, and classified applications by the port number. We found that the main flows contributing to the non-Gaussian nature of network traffic were HTTP flows with relatively small hop counts compa...

15 صفحه اولViscosity of glass-forming liquids.
The low-temperature dynamics of ultraviscous liquids hold the key to understanding the nature of glass transition and relaxation phenomena, including the potential existence of an ideal thermodynamic glass transition. Unfortunately, existing viscosity models, such as the Vogel-Fulcher-Tammann (VFT) and Avramov-Milchev (AM) equations, exhibit systematic error when extrapolating to low temperatur...
متن کاملThermoviscoelasticity of glass-forming liquids
In supercooled liquids structural relaxation shows up as a frequency dependence of mechanical and thermal properties such as the adiabatic bulk modulus, Ks, shear modulus, G, expansion coecient, ap, and isobaric speci®c heat, cp. Whereas Ks and G can be measured directly, we claim this is dicult for cp. Near the glass transition where cp diers signi®cantly from the isochoric speci®c heat, cv...
