Kovacs effect in glass with material memory revealed in non-equilibrium particle interactions

Autor: Chun-Shing Lee, Matteo Lulli, Chi Hang Lam, Ling-Han Zhang, Hai-Yao Deng

The Kovacs effect is a remarkable feature of the ageing dynamics of glass forming liquids near the glass transition temperature. It consists in a non-monotonous evolution of the volume/enthalpy after a succession of two abrupt temperature changes: fi

Fragile Glasses Associated with a Dramatic Drop of Entropy under Supercooling

Autor: Ling Han Zhang, Chi Hang Lam, Matteo Lulli, Hai-Yao Deng, Chun Shing Lee

Publikováno v: Physical review letters. 125(26)

We perform kinetic Monte Carlo simulations of a distinguishable-particle lattice model of structural glasses with random particle interactions. By varying the interaction distribution and the average particle hopping energy barrier, we obtain an extr

Configuration-tree Theoretical Calculation of the Mean-Squared Displacement of Particles in Glass Formers

Autor: Matteo Lulli, Ling-Han Zhang, Chun-Shing Lee, Chi Hang Lam, Hai-Yao Deng

We report an analytical evaluation of the mean-squared displacement (MSD) of the particles in glasses based on their coarse grained trajectories. The calculation is conducted by means of a local random configuration-tree theory that was recently prop

Emergent facilitation behavior in a distinguishable-particle lattice model of glass

Autor: Chi Hang Lam, Ling-Han Zhang

Publikováno v: Physical Review B. 95

We propose an interacting lattice gas model of structural glass characterized by particle distinguishability and site-particle-dependent random nearest-neighboring particle interactions. This incorporates disorder quenched in the configuration space

Cigarette Filter Rod Parameter Measure Based on Otsu Image Processing

Autor: Shu Bin Yang, Shu Long Fu, Ling Han Zhang, Lu Jin

Publikováno v: Applied Mechanics and Materials. :635-639

Traditional contacting measure method can easily cause cigarette filter rod distortion and needs long measure time. Its measure precision is difficult to satisfy practice demand and it cannot implement online measure. In order to overcome these short

Predicting Seepage of Earth Dams Using Neural Network and Genetic Algorithm

Autor: Jing Qiao, Chu Jinkui, Ling Han Zhang, Xin Ying Miao

Publikováno v: Advanced Materials Research. :3081-3085

Measurements of seepage are fundamental for earth dam surveillance. However, it is difficult to establish an effective and practical dam seepage prediction model due to the nonlinearity between seepage and its influencing factors. Genetic Algorithm f
