A phase-change memory (PCM) model for robust and efficient simulations of circuits including neuromorphic ones is reported in this work. The features a hysteretic dynamic resistance the voltage domain, incubation crystallization, are covered model. Landau-Khalatnikov (LK)-type equation ferroelectric used to develop PCM hysteresis module. voltage-controlled relaxation oscillation successfully si...

This paper presents a thermo-mechanical model with phase transition considering changes in the mechanical properties of medium. The proposed is described by system partial differential equations for temperature and displacements. In model, soil deformations occur due to porosity growth caused ice water density differences. A finite-element approximation this on fine grid presented. linearizatio...

Phase-change memory technology relies on the electrical and optical properties of certain materials changing substantially when the atomic structure of the material is altered by heating or some other excitation process. For example, switching the composite Ge(2)Sb(2)Te(5) (GST) alloy from its covalently bonded amorphous phase to its resonantly bonded metastable cubic crystalline phase decrease...

the modified nrtl (m-nrtl) model is used to represent the excess gibbs free energy of aqueous (alcohol + electrolyte) solutions. in this work, the m-nrtl model previously developed for representation of vapor-liquid equilibria for (polymer + salt + water) systems has been extended to represent liquid-liquid equilibria of (alcohol + salt + water) systems. the proposed extension is a modified of ...
