Sequential Monte Carlo Methods for Discharge Time Prognosis in Lithium-ion Batteries
International Journal of Prognostics and Health Management, 2012 This paper presents the implementation of a particle-filtering-based prognostic framework that allows estimating the state-of-charge (SOC) and predicting the discharge time of energy storage devices (more specifically lithium-ion batteries). The proposed

Spatially inhomogeneous states of charge carriers in graphene
JETP Letters, 2007 We study an interaction of 2D quasiparticles with linear dispersion (graphene) with impurity potentials. It is shown that in 1D potential well (quantum wire) there are discrete levels, corresponding to localized states, whereas in 2D well (quantum dot) there are no such states.
