General Dynamical Sharp-interface Conditions for Phase Transformations in Viscous Heat-Conducting Fluids, Journal of Fluid Mechanics, to be published The purpose of this paper is to develop, from basic considerations, a complete set of equations governing the evolution of a sharp interface separating two fluid phases undergoing transformation. For situations in which a phase transformation does not occur, so that the phase interface is a material surface, the governing bulk and interfacial equations are well-developed and agreed upon. Focusing on the interface, the relevant equations are the conventional balances for mass, linear momentum, and energy, augmented by suitable constitutive equations. But when a phase transformation does occur, the interfacial expressions for balance of mass, momentum, and energy fail to provide a closed description and must be supplemented by an equation that accounts for the microphysics underlying the exchange of material between phases. For this purpose we employ the formalism of configurational forces to derive the appropriate generalization of the Gibbs-Thomson equation for a fluid-fluid interface under non-equilibrium conditions. In this paper, an error analysis based on boundary error popularity including semantic boundary categorization is applied in the context of the news story segmentation task from TRECVID, Clusters of systems were defined based on the input resources they used including video, audio and automatic speech recognition. A cross-popularity specific index was used to measure boundary error popularity across cluster, which allowed goal-driven selection of boundaries to be categorized. A wide set of boundaries was viewed and a summary of the error types is presented. This framework allowed drawing conclusions about the behavior of resource-based clusters in the context of news story segmentation. In many experimental settings, different types of factors affect the measured response. The factors that can be set independently of each other are called crossed factors. Nested factors cannot be set independently because the level of one factor takes on a different meaning when other factors are changed. Random nested factors arise from quantity designations and from sampling and measurement procedures. The variances of the random effects associated with nested factors are called variance components. Factor effects on the average are called location effects. Dispersion effects are the effects of the crossed factors on the variance of a response. For situations where crossed …
